Description

  The present invention relates to a construction method for a high-rigidity surface body in which a plurality of plate materials are arranged with their side surfaces facing each other to form a high-rigidity surface body, and a connection member used for the construction of the high-rigidity surface body.

  In recent wooden constructions, floors and walls are constructed using structural plywood members such as pillars and beams, and wallpaper or flooring is applied on the structural plywood. The mainstream is that the walls and floors are finished. Such structural plywood has very excellent characteristics in structural strength, and although modern architecture using this is robust, structural plywood, wallpaper, flooring such as flooring, etc. are artificial. Such wooden construction lacks the texture of natural materials.

  By the way, as an ancient Japanese construction method, there is a construction method called a construction method that exposes as it is without covering pillars and beams, etc., and arranges cedar boards and other boards in a plane to form the floor and ceiling and expose them as they are. Exists. This construction method is rich in the unique texture of natural materials, and is excellent both in terms of indoor environment and design.

  For this reason, in recent years, with the emergence of problems for the entire building and the increasing demand for high-value-added buildings, the popularity of architectures (especially houses) that actively incorporate these types of construction methods has increased. Yes.

  Here, a typical structure of the represented construction method will be described. For example, the floor of the represented construction method is configured by laying the plate material 20 directly on the beam 40 as shown in FIG. The floor of such a construction method allows the plate material 20 laid on the beam 40 to function as a floor surface as it is (see FIG. 13A), and also functions as a ceiling when viewed from below. (See FIG. 13B).

  Further, the construction method of the construction method is to arrange a plurality of plate members 20, 20... Facing each other. Specifically, the plate member 20 is placed on the beam 40, and the side surfaces of the plate member 20. A fixing member such as a screw is driven obliquely from the top to the beam 40, and the fixing member is driven from the upper surface of the plate member 20 toward the beam to fix the plate member 20 to the beam 40.

  However, in the floor according to the above-described construction method, the plate members 20, 20,... And the beam 40 are firmly fixed by the fixing members, but the plate members 20, 20 are not connected to each other. Here, the floor is preferably structurally preferable (see FIG. 14A) in which the entire floor is integrally displaced without being deformed when a force is applied from the lateral direction. When a force is applied from the lateral direction, the plate members 20 and 20 are displaced separately, and the floor 20 is deformed while the plate members 20 and 20 slide relative to each other (see FIG. 14B). The yield strength in the direction is low, and for example, the in-plane rigidity tends to be inferior to a floor constructed using a structural plywood.

  Therefore, the present invention forms a high-rigidity surface body that can increase the in-plane rigidity by improving the proof stress in the sliding direction of the plate material, and thus the construction of the high-rigidity surface body that can contribute to increase the rigidity of the structure. It is an object to provide a method and a connecting member used to form such a highly rigid face.

  A construction method for a highly rigid face according to the present invention is a construction method for a highly rigid face that forms a highly rigid face by arranging a plurality of plate materials with their side surfaces facing each other, and one of the two facing plate materials. A one-side entry portion that enters the side surface of the first plate, a second-side entry portion that is provided in a direction opposite to the one-side entry portion and enters the side surface of the other plate member, and the one-side entry portion and the other-side entry portion. And a connecting member provided with a crossing portion provided along a direction intersecting them, and the one side intrusion portion is plunged into the side surface of one plate member along the opposing direction of the side surfaces, and the other side plunging into place. And projecting a portion into the side surface of the other plate member along the facing direction, and connecting the facing plate members together to construct a highly rigid face body with the intersecting portion sandwiched between both plate members. Features.

  According to the construction method of the highly rigid face body having the above configuration, the opposing plate members are firmly connected by the connecting member. And when force acts in the sliding direction of a board | plate material, it will be in the state which receives a force from a mutually different direction in a one side intrusion part and the other side intrusion part. At this time, since the intersecting portion is sandwiched between both plate members, even if the connecting member tries to rotate around a portion (that is, the intersecting portion) located between the opposing plate members. The intersecting portion interferes with the plate material and rotation is restricted.

  Further, the one plate material driven into the side surface to the intersection and the other plate material are brought close to each other so that the side surfaces are in contact with each other, and the other side entry portion of the connection member is made the other plate material. A configuration for rushing into is preferable.

  According to the said structure, the said connection member is driven into a side surface to the said cross | intersection part to the said one board | plate material, and the said other side protrusion part is the state protruded from one board | plate material. When a force is applied to the two plate members so that the side surfaces approach each other, the other-side entry portion enters the other plate member. At this time, the connecting member is restricted from further immersing in the one plate material side because the intersecting portion contacts the one plate material. Therefore, when the side surfaces of the opposing plate materials are brought into contact with each other, a state in which the intersecting portion is sandwiched between the two plate materials is realized.

  Further, a convex portion is provided on the side surface of one of the opposing plate materials along the longitudinal direction of the side surface, and a concave portion joined to the convex portion is provided on the side surface of the other plate material in the longitudinal direction of the side surface. It is preferable that the first side protrusion of the connecting member is inserted into the convex portion of the one plate member, and the other side protrusion portion is inserted into the concave portion of the other plate member.

  According to the above configuration, the protruding plate portions are provided on the side surfaces of one of the facing plate materials, and the recessed portions that are fitted to the protruding portions are provided on the side surfaces of the other plate material. In addition, the plate members can be joined together at the seam, so that the opposing plate members can be joined together without any gaps. In addition, since the one-side protruding portion of the connecting member is allowed to enter the convex portion of the plate material, positioning can be easily performed. Furthermore, since the convex part of the said board | plate material protrudes outward from the main-body part, the workability | operativity when driving a connection member to the said cross | intersection part is good.

  Further, the connecting member is provided in a straight line with a pair of the one side entry part and the other side entry part, and at least two pairs of the one side entry part and the other side entry part are provided, It is preferable that the driving force is applied to a portion between the two other side protruding portions at the crossing portion of the connecting member to cause the one side protruding portion to enter the side surface of the one plate member.

  According to the above configuration, when the one side entry portion enters the plate material, the connecting member hits the plate material at at least two places, so that the stability does not increase and the workability is good. In addition, by applying a driving force to the portion between the two other side entry parts, the force acts on the two one side entry parts in a well-balanced manner, and the workability can be further improved.

  By the way, when a force in the sliding direction is applied, the connecting member tries to rotate around the continuous portion of the intruding portion and the intersecting portion, but the portion farther from the position that can be the center of rotation among the portions that interfere with the plate material. It greatly contributes to the difficulty of rotation (that is, the rotational moment), and the closer it is, the less it contributes. In this regard, according to the above configuration, since there are a plurality of positions that can be the center of rotation due to a plurality of plunging portions that enter each plate member, one specific position on the intersection may be a center of rotation. Even if they are close to each other, the specific location is separated from the position that can be another rotation center by a predetermined distance. As a result, many locations on the intersection greatly contribute to the rotational moment.

  Alternatively, the connecting member according to the present invention has a convex portion provided on the side surface of one of the two opposing plate materials along the longitudinal direction of the side surface and the side surface of the other plate material along the longitudinal direction of the side surface. When connecting a plurality of plate materials to form a highly rigid face body by joining the recessed portions provided in the above, the connection member is used to connect the opposed plate materials to each other along the facing direction of the opposed plate materials. The one side intrusion portion that enters the convex portion of the one plate material, the other side intrusion portion that is provided facing the opposite direction to the one side intrusion portion, and that enters the concave portion of the other plate material, and the one side intrusion portion And an intersection portion that is provided along a direction that is continuous with and intersects with the other side intrusion portion and is sandwiched between the convex portion and the concave portion.

  According to the connection member which consists of the said structure, the board | plate materials which oppose can be connected firmly. And when force acts in the sliding direction of a board | plate material, it will be in the state which receives a force from a mutually different direction in a one side intrusion part and the other side intrusion part. At this time, since the intersecting portion is sandwiched between both plate members, even if the connecting member tries to rotate around a portion (that is, the intersecting portion) located between the opposing plate members. The intersecting portion interferes with the plate material and rotation is restricted. In addition, since the one-side protruding portion of the connecting member is allowed to enter the convex portion of the plate material, positioning can be easily performed.

  In addition, when driven into the convex portion provided on the side surface of the one plate material up to the intersecting portion, the dimension is such that the tip of the one side entry portion enters the one plate material to a position exceeding the base end portion of the convex portion. The configuration to be set is preferable.

  According to the said structure, if the said connection member is made to immerse into the convex part of one board | plate material to the cross | intersection part, the front-end | tip of one side penetration part will penetrate into a main-body part exceeding the convex part of the said board | plate material. Here, the tip of the one side entry portion extends to the main body portion of the plate material, and since the main body portion is thicker than the convex portion, it is possible to increase the resistance to the force in the sliding direction of the high-rigid face. . Furthermore, since the convex part of the said board | plate material protrudes outward from the main-body part, the workability | operativity when driving a connection member to the said cross | intersection part is good.

  In addition, when driven into the convex portion provided on the side surface of the one plate material up to the intersecting portion, the dimension is such that the tip of the one side entry portion enters the one plate material to a position exceeding the base end portion of the convex portion. The configuration to be set is preferable.

  According to the above configuration, when the one side entry portion enters the plate material, the connecting member hits the plate material at at least two places, so that the stability does not increase and the workability is good. In addition, by applying a driving force to the portion between the two other side entry parts, the force acts on the two one side entry parts in a well-balanced manner, and the workability can be further improved.

  Moreover, the said 1 side intrusion part, the other side intrusion part, and the cross | intersection part have the structure where the cross section orthogonal to the length direction of these each part curves is formed.

  According to the above configuration, each part of the one-side entry part, the other-side entry part, and the intersecting part is formed to be curved, so that rigidity can be increased and each part can effectively function as a pressure receiving part. Can do. Accordingly, when the one-side entry portion and the other-side entry portion are inserted into the plate material or when the force in the sliding direction is applied, deformation of each portion is suppressed, so that the plate materials can be reliably connected to each other. Further, it is possible to increase the proof strength of the high-rigidity surface body against the force in the sliding direction.

  As described above, according to the present invention, it is possible to improve the in-plane rigidity by improving the proof stress in the sliding direction of the plate material, thereby forming a high-rigid surface body that can contribute to increasing the rigidity of the structure. be able to.

  As shown in FIG. 1, the connecting member 1 according to the first embodiment forms a highly rigid face body 10 as shown in FIG. 2 by arranging a plurality of plate members 20, 20. The plate members 20 and 20 are connected to each other, one of the two plate members 20 and 20 facing each other, the one side protrusion portion 2 that protrudes into the side surface 21 of the plate member 20, and the one side protrusion portion 2 Is provided in the opposite direction, and is continuous with the other side entry part 3 that enters the side surface 22 of the other plate member 20, and the one side entry part 2 and the other side entry part 3 along a direction that intersects them. And a crossing portion 4 sandwiched between both plate members 20 and 20.

  First, the plate material 20 used for constructing the high-rigid face 10 will be described. The plate member 20 is a long body having a predetermined thickness. As the material, it is preferable to use natural wood such as cedar board, for example, from the viewpoint of design, the influence on the human body, and the strength. Each plate member 20 protrudes outward from the main body 23 along the longitudinal direction of the side surface 21 on one side surface 21 (generally called “side”) of the two side surfaces 21 and 22 along the longitudinal direction. A convex portion 24 is formed, and a concave portion 25 is formed on the other side surface 22 along the longitudinal direction of the side surface 22, and the plurality of plate members 20, 20 are fitted with the convex portion 24 and the concave portion 25. It joins together without providing a gap. In general, the convex portion 24 is called “real”, the concave portion 25 is called “small hole”, and such a joining method is called “real rowing”.

  Further, the convex portion 24 is provided at an intermediate position in the thickness direction of the plate member 20 on the side surface 21. The recess 25 is formed corresponding to this, and is similarly provided at an intermediate position in the thickness direction of the plate member 20 on the side surface 22. The plate member 20 is a so-called thick plate. Specific dimensions include a thickness of the main body portion 23 of 40 mm, a width of 160 mm, a thickness (width) of the convex portion 24 and a width of the concave portion 25 of 10 mm, and a convex portion. The height (projection amount) of 24 and the depth of the concave portion 25 are 10 mm, and the centers in the width direction of the convex portions 24 and the concave portions 25 are provided to coincide with the centers in the thickness direction of the plate member 20.

  Next, the connecting member 1 has a shape as shown in FIG. 3, and the protruding portion 24 of the one plate member 20 is formed so that the one-side entry portion 2 extends in the facing direction of the opposed plate members 20, 20. The other side entry portion 3 enters the concave portion 25 of the other plate material 20 along the opposing direction of the plate materials 20, 20, and the intersecting portion 4 is between the convex portion 24 and the concave portion 25. Sandwiched. Specifically, the intersecting portion 4 is provided so as to extend along a direction orthogonal to the projecting direction of the one-side intrusion portion 2 and the other-side intrusion portion 3, that is, the intersecting portion 4 is provided in the one-side intrusion. It is orthogonal to the part 2 and the other side entry part 3.

  The one side intrusion portion 2, the other side intrusion portion 3, and the intersecting portion 4 have high rigidity so as not to be deformed when driven in or into the plate member 20. Each of the parts 2, 3, and 4 is integrally formed, and when the battery is driven or plunged into the plate member 20, the one side intrusion part 2 and the intersecting part 4 and the other side intrusion part 3 and the intersecting part 4 are formed. The continuous portions are also set to have high rigidity so that they can be maintained orthogonal to each other.

  Further, when the connecting member 1 is driven into the convex portion 24 provided on the side surface 21 of the one plate member 20 up to the intersecting portion 4, the distal end of the one-side entry portion 2 exceeds the proximal end portion of the convex portion 24. The dimensions are set so as to enter the one plate member 20 up to the position (that is, up to the main body portion 23) (see FIG. 5).

  And as shown in FIG. 3, the said one side penetration part 2 and the other side penetration part 3 are sharply formed in the front end side. Further, each of the rush portions 2 and 3 is formed solid. Specifically, the one-side entry portion 2 includes a shaft portion 2a formed to have the same width in side view and a tip portion 2b having a sharp shape. The shaft portion 2 a has a length that reaches the main body portion 23 of the plate member 20 in a state where the shaft portion 2 a is driven into the convex portion 24 up to the intersecting portion 4. That is, the length in the height direction from the portion facing the other end side of the intersecting portion 4 to the boundary portion between the shaft portion 2a and the tip portion 2b is set larger than the height (projection amount) of the convex portion 24. The Further, the one-side entry part 2 is formed longer than the other-side entry part 3.

  Moreover, the said one side intrusion part 2 and the other side intrusion part 3 make a pair, and are provided on a straight line. Further, at least two pairs of the one side intrusion portion 2 and the other side intrusion portion 3 are provided.

  The one side intrusion portion 2 and the other side intrusion portion 3 are provided on a straight line, thereby forming one protrusion 5. That is, the connecting member 1 can be specified as including a linearly formed protrusion 5 and an intersecting portion 4 extending from a middle position of the protrusion 5 along the direction intersecting the protrusion 5. A portion protruding to one side from a position where the protrusion 5 and the intersecting portion 4 are connected (the intermediate position) corresponds to the one side intrusion portion 2, and a portion protruding to the other side corresponds to the other side intrusion portion 3. To do. Moreover, it can also specify as providing the protrusion 5 which protrudes along the direction which cross | intersects this intersection part 4 from the both ends of the said intersection part 4. FIG.

  The intersecting portion 4 directly receives a driving force applied when the connecting member 1 is driven, and functions to prevent the sinking by contacting the plate member 20 when the connecting member 1 is driven. Specifically, the portion facing the other side of the intersecting portion 4 is a portion that directly receives driving force, and the portion facing the one side is a portion that functions to prevent sinking.

  In addition, the connection member 1 prepares the metal plate of the thickness considered that preferable rigidity can be implement | achieved, and cut | disconnects this metal plate to the shape of a connection member by press, laser cutting, etc., and is manufactured.

  Moreover, the connection member 1 is set smaller than the thickness of the convex part 24 of the said board | plate material 20, and as a specific dimension, width is set to 40 mm, height is set to 30 mm, and thickness is set to 4 mm. Further, the tip end portions 2b and 3b of the one side entry portion 2 and the other side entry portion 3 are provided in a region 6 mm from each tip, and the shaft portions 2a and 3a of the one side entry portion 2 and the other side entry portion 3 are provided. The width is set to 4 mm. The width of the intersecting portion 4 is set to 4 mm, and the center line of the intersecting portion 4 is provided at a position of 18 mm from the tip of the one-side entry portion 2 (12 mm from the tip of the other-side entry portion 3).

  Next, a method for constructing a highly rigid face using the connecting member 1 as described above will be described. As shown in FIG. 1 and FIG. 4, the high-rigid surface body is constructed by arranging a plurality of plate members 20, 20... It is a method, The one side protrusion part 2 of the said connection member 1 is protruded in the side surface 21 of one board | plate material 20 along the opposing direction of side surfaces, and the other side protrusion part 3 is made into the other board | plate material along the said opposing direction. The high rigidity face 10 (see FIG. 2) is connected by connecting the opposing plate members 20 and 20 with the crossing portion 4 being sandwiched between the two plate members 20 and 20. It is to be constructed.

  In the construction, as shown in FIG. 4, the one side plate 20 and the other side plate 20 in which the connecting member 1 is driven into the side surface to the intersecting portion 4 are brought into contact with each other. It is made to approach so that the other side penetration part 3 of the said connection member 1 may rush into the said other board | plate material 20.

  By the way, in the construction method of the high-rigidity face piece, first, after manufacturing the plate material 20 in which the connecting member 1 is driven to the intersecting portion 4, the construction of the high-rigidity face piece 10 is finally completed.

  Specifically, first, a plate member 20 having the convex portions 24 formed on the side surface 21 along the longitudinal direction is prepared. Next, the connecting member 1 is driven into the intersecting portion 4 by causing the one-side protruding portion 2 of the connecting member 1 to enter the side surface 21 (convex portion 24) of the plate member 20. The connecting member 1 is driven until the flat portion 4b of the intersecting portion 4 is flush with the end surface of the convex portion 24 (see FIG. 5).

  When the connecting member 1 is driven, a driving force is applied to the portion between the two other side entry portions 3 and 3 at the intersection 4 of the connecting member 1 by using a hammer or a driving machine. The one-side entry part 2 is made to enter the side surface 21 of the one plate member 20. The connecting member 1 is driven into the side surface 21 of the plate member 20 at an interval of 910 mm. In addition, as such a driving machine, for example, the other-side entry part 3 is held in a state having play by a holding part having a shape corresponding to the other-side entry part 3, and the other-side entry part is provided at the time of driving. 3 is preferable, and the connecting member 1 is preferably positioned so as to be orthogonal to the side surface 21 of the plate member 20 and driven straight.

  Next, the plurality of plate members 20, 20... Are arranged with the directions of the convex portions 24 and the concave portions 25 aligned. For example, when constructing the floor 11 on the second floor of a building as shown in FIG. 2, the plate members 20 are arranged on the beam 40 (see FIG. 4) from the end of the region where the floor 11 is constructed. In that case, the board | plate materials 20 and 20 are joined by fitting the recessed part 25 of another board | plate material (other board | plate material) 20 to the convex part 24 of the board | plate material (one board | plate material) 20 arrange | positioned previously.

  Specifically, the other plate member 20 is placed in front of one plate member 20, and the side surface 21, 22 of the other plate member 20 is opposite to the one plate member 20 (that is, the recess 25 is formed). The plate members 20 and 20 are brought close to each other until the side surfaces 21 and 22 come into contact with each other, for example, by hitting the side surface 22). As a result, the other-side entry portion 3 of the connecting member 1 enters the recess 25 of the other plate member 20. FIG. 5 shows a state in which the plate members 20 are connected to each other by the connecting member 1.

  By the way, when constructing the high-rigidity surface body, each plate member 20 is fixed to the beam 40 by driving a fixing member 50 such as a screw or a nail vertically from the upper surface. The fixing of the plate member 20 is performed every time each plate member 20 is arranged on the beam, but is not limited to this, and is performed collectively after arranging the plurality of plate members 20 in a planar shape. It may be a thing. Further, after the fixing member 50 is driven, dowel filling is performed in order to conceal the head of the fixing member 50 and close a hole formed by driving the fixing member 50.

  As described above, according to the connection member 1 and the method for constructing the highly rigid face body according to the present embodiment, the in-plane rigidity can be increased by improving the proof stress in the sliding direction of the plate member 20, and consequently the rigidity of the structure body. It is possible to form the highly rigid face body 10 that can contribute to the enhancement.

  That is, according to the construction method of the connecting member 1 and the highly rigid face body, the opposing plate members 20 and 20 are firmly connected by the connecting member 1. When a force is applied in the sliding direction of the plate member 20, as shown schematically in FIG. 6, the one side entry portion 2 and the other side entry portion 3 receive a force F from different directions. . At this time, since the intersecting portion 4 is in a state of being sandwiched between the two plate members 20 and 20 while being immersed in one plate member 20, the portion located between the opposed plate members 20 and 20 Even if the connecting member 1 tries to rotate around (the intersecting portion 4), the intersecting portion 4 interferes with the plate member 20 and receives a drag force R, so that the rotation is restricted.

  Further, the connecting member 1 is driven into the side surface 21 up to the intersecting portion 4 in the one plate material 20, and the other side intrusion portion 3 protrudes from the one plate material 20. When a force is applied to the two plate members 20, 20 so that the side surfaces 21, 22 are close to each other, the other side entry portion 3 enters the other plate member 20. At this time, since the intersecting portion 4 abuts on the one plate member 20, the connecting member 1 is restricted from being further immersed in the one plate member 20 side. Therefore, when the side surfaces 21 and 22 of the opposing plate members 20 and 20 are brought into contact with each other, a state in which the intersecting portion 4 is sandwiched between the both plate members 20 and 20 is realized.

  And the convex part 24 is provided in the side surface 21 of one board | plate material 20 among the board | plate materials 20 and 20 which oppose, and the recessed part 25 fitted to the said convex part 24 is provided in the side surface 22 of the other board | plate material 20. Thus, the opposing plate members 20 and 20 can be closely bonded to each other, and the plate members 20 and 20 are overlapped with each other at the seam, so that the opposing plate members 20 and 20 can be bonded together without a gap. Further, since the one-side intrusion portion 2 of the connecting member 1 is caused to enter the convex portion 24 of the plate member 20, the positioning can be easily performed. Furthermore, since the convex part 24 of the said board | plate material 20 protrudes outward from the main-body part 23, the workability | operativity when driving the connection member 1 to the said cross | intersection part 4 is good.

  Further, since the connecting member 1 hits the plate member 20 at least at two places when the one-side entry portion 2 enters the plate member 20, stability is not increased and the workability is good. In addition, by applying a driving force to the portion between the two other side entry parts 3 and 3, the force acts on the two one side entry parts 2 and 2 in a well-balanced manner, further improving workability. Can be better.

  By the way, when the force in the sliding direction is applied, the connecting member 1 tries to rotate around the continuous portion of the piercing portions 2, 3 and the intersecting portion 4, but becomes the center of rotation among the portions that interfere with the plate member 20. The farther from the position to be obtained, the greater the contribution to the difficulty of rotation (that is, the rotational moment), and the smaller the contribution, the smaller the contribution. In this regard, according to the above configuration, since there are a plurality of the plunging portions 2 or 3 that plung into the respective plate members 20, 20, there are a plurality of positions that can be the rotation center, so that a certain specific place on the intersecting portion 4 is Even if it is close to one of the positions that can be the center of rotation, the specific part is separated from the position that can be another center of rotation by a predetermined distance, and as a result, many parts on the intersection 4 become rotational moments. It will greatly contribute.

  Further, when the connecting member 1 is immersed in the convex portion 24 of the one plate material 20 up to the intersecting portion 4, the tip of the one side entry portion 2 enters the main body portion 23 beyond the convex portion 24 of the plate material 20. Here, the front end of the one side entry portion 2 extends to the main body portion 23 of the plate member 20, and the main body portion 23 is thicker than the convex portion 24, so that the high-rigidity surface body 10 is resistant to the force in the sliding direction. Yield can be increased.

  And the said connection member 1 can raise rigidity by each part of the said one side intrusion part 2, the other side intrusion part 3, and the cross | intersection part 4 being curved, and each part 2, 3, 4 can effectively function as a pressure receiving portion. Therefore, when the one side entry part 2 and the other side entry part 3 enter the plate member 20 or when a force in the sliding direction is applied, the deformation of the portions 2, 3, 4 is suppressed, While being able to connect 20 reliably, the proof strength with respect to the force of the said sliding direction of the highly rigid face body 10 can be improved.

  By the way, when the highly rigid face body 10 is constructed using the connecting member 1 and the connecting member 1 as described above, the floor magnification, which is an index representing the rigidity of the floor, is a value generally called “rigid floor” of 3.0. It was confirmed by calculation that the above can be achieved theoretically. As described above, the connecting member 1 and the high-rigid face 10 constructed using the connecting member 1 can achieve a floor magnification that cannot be realized by the conventional construction method using only a fixing member such as a screw. It has also been theoretically confirmed that it will have a rigidity comparable to that of a floor constructed using conventional structural plywood.

<Second embodiment>
As shown in FIG. 7, the connecting member 60 according to the second embodiment basically has the same configuration as that of the connecting member 1 according to the first embodiment. The other side intrusion portion 63 has a shape in which a cross section perpendicular to the length direction of each of the portions 62 and 63 is bent. Further, the intersecting portion 64 also has a shape in which a cross section perpendicular to the length direction thereof (that is, the direction intersecting with each of the entry portions) is bent. Specifically, the one side intrusion portion 62, the other side intrusion portion 63, and the intersecting portion 64 are formed by bending a cross section perpendicular to the length direction of each of the portions 62, 63, 64. Such a connecting member 60 is formed using a metal plate. As the material, a hot rolled steel plate called SPHC is used.

  The intersecting portion 64 is formed to have a flat surface along a direction orthogonal to each of the entry portions 62 and 63. More specifically, the intersection 64 includes a connection part 64a that connects the pair of protrusions 65 and 65, and a flat part 64b that is provided continuously to the connection part 64a.

  In addition, a reinforcing portion (or rib portion) 66 is provided at a connection portion between the other side intrusion portion 63 and the intersecting portion 64. The reinforcing portion 66 connects the tip portion of the other-side entry portion 63 and the intersection portion 64 in such a manner as to fill a corner defined by the other-side entry portion 63 and the intersection portion 64. Specifically, the reinforcing portion 66 has edges that incline in the length directions of the other side intrusion portion 63 and the intersecting portion 64. And the reinforcement part 66 is provided so that the said flat site | part 64b may be provided in the length direction (namely, direction where the intersection part 64 is extended) of the said intersection part 64. As shown in FIG. In addition, the edge of the reinforcing portion 66 is formed in a curved shape at a continuous portion with the edge facing the one side of the connection portion 64a, and the edges are smoothly continuous.

  As a manufacturing method of the connecting member 60, first, the entire shape of the portions 72, 73, and 74 that become the one side intrusion portion 62, the other side intrusion portion 63, and the intersection portion 64 as shown in FIG. A flat raw material 70 having the following is cut from a metal plate. Next, the portions 72 and 73 to be the one side intrusion portion 62 and the other side intrusion portion 63 of the flat raw material 70 are bent along the length direction at the intermediate position in the width direction, and the connection portion 64a at the intersection portion 64 is obtained. The boundary between the portion 74a that becomes the portion 74b and the portion 74b that becomes the flat portion 64b is bent along its length direction. Further, the portions 72 and 73 that become the one-side intrusion portion 62 and the other-side intrusion portion 63 are bent at a position that protrudes most in the height direction of the connecting member 60.

  In addition, the flat raw material 70 in the previous stage where the bending process is performed has an overall shape. In this state, the portions 72 and 73 that become the respective rush portions 62 and 63 are located on both sides of the portion 74 that becomes the intersecting portion 64. In addition, the part 74b used as the flat part 64b of the said cross | intersection part 64 is protruded and provided in the other side of the part 74a used as the connection part 64a. In addition, the portion 74a that becomes the connection portion 64a is formed continuously with the portions 72 and 73 that become the respective entry portions 62 and 63, but the portion 74b that becomes the flat portion 64b can be bent. It is formed by being divided into portions 72 and 73 to be the respective intrusion portions 62 and 63. The reinforcing portion 66 is located on one side of the portion 74 that becomes the intersecting portion 64, and is provided continuously with the portions 72 and 73 that become the respective entry portions 62 and 63 and the portion 74 that becomes the intersecting portion 64.

  In addition, the connecting member 60 is set to be smaller than the thickness of the convex portion 24 of the plate member 20, and specific dimensions include a width of 44 mm, a height of 30 mm, and bending of each of the intrusion portions 62 and 63. The thickness (side view width) including the portion and the flat portion 64b is set to 5 mm.

  In addition, the construction method of the connection member and the highly rigid face body according to the present invention is not limited to the above embodiments, and various modifications can be made without departing from the gist of the present invention.

  For example, the connecting member may have various shapes. For example, as shown in FIG. 8 (A), the connecting member 80 is formed with the same width, but the tip end portions of the one side entry portion 82 and the other side entry portion 83 are not sharply formed. Also good. Moreover, the connection members 90 and 100 as shown to FIG. 8 (B) and (C) may be sufficient. Further, as shown in FIGS. 8D and 8E, the connecting members 110 and 120 may be different in the number of the one side intrusion portions 112 and 122 and the other side intrusion portions 113 and 123. As shown in FIG. 8 (F), the connecting member 130 that protrudes from a different position of the intersecting portion 134 may be used as the one-side protruding portion 132 and the other-side protruding portion 133.

  Further, as shown in FIGS. 9A and 9B, connection members 140 and 150 in which only one of the one side intrusion portions 142 and 152 and the other side intrusion portions 143 and 153 are provided may be used. Even in this case, when the intersecting portions 144 and 154 are sandwiched between the two plate members, the intersecting portions 144 and 154 interfere with the plate member and the rotation of the connecting members 140 and 150 is restricted. .

  Furthermore, as shown in FIG. 9C, if the intersecting portion 164 is provided along the direction intersecting the one side intrusion portion 162 and the other side intrusion portion 163, the intersection portion 164 is along the intersecting direction. The connection member 160 which does not have a linear shape may be sufficient. In addition, the connecting member 160 shown in FIG. 9C is formed continuously without the one side intrusion portion 162 and the other side intrusion portion 163 and the intersecting portion 164 having a clear boundary. Further, the one side intrusion portion 162 or the continuous portion of the other side intrusion portion 163 and the intersecting portion 164 can also function as the reinforcing portion 166.

  Moreover, even if the cross section perpendicular to the length direction of the one side intrusion portion, the other side intrusion portion, and the intersecting portion is formed in a curved shape, various shapes are conceivable. For example, as shown in FIG. 10A, a connecting member 170 in which the reinforcing portion 176 is formed large may be used. Also, as shown in FIG. 10B, the bending positions of the one-side entry part 182 and the other-side entry part 183 may not coincide with the position where the connection member 180 protrudes most in the height direction. As shown in FIG. 10C, a connecting member 190 that is not provided with a reinforcing portion may be used.

  In the connecting member 1 according to the first embodiment, the one side intrusion portion 2 and the other side intrusion portion 3 are solidly formed. It may be hollow and formed by opening both end faces in the driving direction. As an example thereof, as shown in FIG. 11A, a connecting member 200 having a cylindrical shape is conceivable, and an intersecting portion 204 of the cylindrical connecting member 200 is located at an intermediate position along the height direction of the tube. It is provided so as to divide the space. Preferably, it is configured to allow air inside the cylinder to escape when the connecting member 200 is driven, and for example, a slit may be formed along the height direction of the cylinder.

  By the way, when the cylindrical connecting member 200 is driven into a plate material, after the one side entry portion 202 is directed to the plate material 20, a rod body is inserted from the opening of the other side entry portion 203, and the rod body It is conceivable that a driving force is applied to the intersecting portion 204 via the. In addition, the cylindrical connecting member 200 can be specified as one in which each entry portion is hollow and open, but is specified as one in which solid entry portions are continuously formed in an annular shape. You can also

  In addition to the cylindrical connection member, the cylindrical connection member 210 may be a rectangular tube connection member 210 as shown in FIG. Furthermore, as shown in FIG. 11 (C), a connecting member 220 obtained by removing one of the outer peripheral surfaces of the square tube may be used.

  The connecting member has been described on the assumption that the intersecting portion is orthogonal to the one side intrusion portion and the other side intrusion portion. However, if the intersecting portion is sandwiched between both plate members, the angle formed with the intrusion portion is a right angle. Instead, the intersecting portion may be inclined with respect to the rush portion. Such a connecting member can also be used to connect plate materials whose side surfaces are along the longitudinal direction, but particularly for connecting tapered plate materials whose side surfaces are inclined with respect to the longitudinal direction. Is preferred. Such joining is also called “battering”.

  Furthermore, as shown in FIG. 12, the one-side entry portion 232 and the other-side entry portion 233 are corrugated when the cross-sections perpendicular to the length direction of the one-side entry portion and the other-side entry portion are bent. The connecting member 230 may have a cross-sectional shape. The connecting member 230 can also be specified as a plurality of protruding portions having a flat plate shape arranged so as to intersect each other and the edges of the plurality of protruding portions being continuous.

  In the construction method of the highly rigid face body according to the above-described embodiment, the plate material having the convex portion 24 and the concave portion 25 is connected to the side surfaces 21 and 22, but is not limited thereto, and the convex portion is provided on the side surface. And what is called the "butting rowing" which connects the board | plate materials which do not have a recessed part may be used.

  In the said embodiment, although demonstrated as what the convex part 24 and the recessed part 25 were provided in the thickness direction intermediate position in the side surfaces 21 and 22 of the board | plate material 20, it is not limited to this, A thickness direction intermediate position is pinched | interposed. It may be in a form called “mutual rowing (so-called phase jump)” in which a convex portion is formed on one side of the side surface and a concave portion is formed on the other side. Moreover, the thing called a "Yaito real rowing" may be sufficient.

  In the above-described embodiment, the one side intrusion portion 2 is actually intruded as the convex portion 24, and the other side intrusion portion 3 is intruded into the small hole as the concave portion 25, but is not limited thereto. The actual side portion may be a concave portion, and the side portion of the small hole may be a convex portion, and each of the intrusion portions may be inserted into the concave portion and the convex portion.

  In the above-described embodiment, the case where a horizontal construction surface such as the floor 11 is constructed as the high-rigidity face 10 has been described as an example. However, the construction method of the high-rigidity face is not limited to the floor 11, and FIG. As shown in FIG. 2, it can also be used to construct a vertical construction surface such as the wall 12 or a horizontal roof construction surface such as the roof (field plate) 13. When the wall 12 is constructed, the plate materials are arranged in the vertical direction. Moreover, it is preferable to fix each board | plate material to a pillar using a fixing member. The wall 12 thus constructed can function as a high strength wall. Further, when the roof (field board) 13 is constructed, the plate material is arranged so as to intersect with the main rafter which is the framework of the roof. Moreover, it is preferable to fix each board | plate material to a purlin using a fixing member.

  In the construction method of the highly rigid face body according to the above embodiment, the step of driving the one side intrusion portion 2 of the connecting member 1 into the plate member 20 has been described as being performed in the field, but the present invention is not limited thereto, and the connection is not limited thereto.
