Description

  TECHNICAL FIELD The present invention relates to a plate-wall bearing wall having a plurality of horizontally long plates stacked between two pillars as a wall, and a floor composed of plates.

  The load-bearing walls of wooden houses include bracing walls, which are modern methods, walls using various face materials such as plywood, earthen walls, surface lattice walls, dropped plate walls, etc., which are traditional methods. These load-bearing walls have a wall magnification set in the Building Standard Law, and a house can be built by designing according to the wall magnification.

  Among these bearing walls, the ones that use plate material as the main material include a wood-clad wall and a drop-in plate wall, but these wall magnifications are set as low as 0.5 and 0.6, respectively. It is very difficult to build a house with only a wooden wall and a dropped wall.

  The traditional dropped board wall has a drawback that it lacks workability because it takes a method of dropping a plurality of board materials into the groove formed on the side of the column sequentially from the upper side to make it a wall material, but in recent years, Ingenuity has been devised to improve workability on site and improve earthquake resistance. For example, as disclosed in Japanese Patent Application Laid-Open No. 08-246580 (Patent Document 1), a single plate material is bonded to form a panel material, and this panel material is dropped into a groove formed on a side surface of a column from the upper side to form a wall material. The idea of being disclosed.

  Japanese Patent Application Laid-Open No. 2007-063767 (Patent Document 2) discloses an idea that a plate material is sequentially dropped from above into a groove formed on a side surface of a column, and then an intermediate column member is nailed into the plate material.

  Further, in Japanese Patent No. 2690259 (Patent Document 3), an opening connected to a groove formed on a side surface of a pillar is cut off to open the groove, and a plate material is inserted from the opening and then sequentially pushed down. Ideas for wall materials etc. are disclosed.

  Japanese Patent No. 3194724 (Patent Document 4) discloses an idea of forming a through-hole penetrating in the vertical direction in a plate material that is sequentially dropped between columns and inserting a bar material into the through-hole. ing.

  Further, in Japanese Patent Application Laid-Open No. 2003-053709 (Patent Document 5), a groove is formed on a plate material, a pier is inserted into a groove formed in a state in which these plate materials are arranged, and a nail or the like from the plate material side toward the pier The idea of driving in a joint fitting is disclosed.

  Furthermore, in the magazine “Wood Industry” Vol. 64, No. 2, 2009, P91-93 (Non-patent Document 1), grooves are formed on the plate materials and the same dimensions as the grooves formed in the state in which these plate materials are arranged. An idea is disclosed in which a plywood is inserted and a joint fitting such as a nail is driven from a plywood side to a back column.

JP 08-246580 A JP 2007-063767 A Japanese Patent No. 2690259 Japanese Patent No. 3194724 JP 2003-053709 A Magazine "Wood Industry" Vol. 64, No. 2, 2009, P91-93

  However, in the technique described in Patent Document 1 described above, although a slight improvement in workability is seen in that only one panel material needs to be attached, a dropped plate wall in which a plurality of horizontally long plate materials are laminated. No taste remains, and there is a problem from the point of design.

  Moreover, since the technique of patent document 2 mentioned above has the process of dropping a board | plate material sequentially, workability | operativity is not improved from the conventional thing, and wall magnification is also 0.9 and is lacking in earthquake resistance.

  Moreover, in the technique of patent document 3 mentioned above, since the board | plate material is dropped sequentially from an opening part after connecting the upper end of a pillar with a horizontal member, the improvement of workability is not seen.

  Further, in the technique described in Patent Document 4 described above, a through hole connected to the plate material is formed. However, this through hole requires high processing accuracy and requires time and effort to insert a bar from above. In addition, earthquake resistance changes with the insertion conditions of a through-hole and a bar, and it cannot be said that earthquake resistance is improved.

  Furthermore, in the technique described in Patent Document 5, a groove is formed in a plate material, a pier is inserted into the groove formed in a state in which the plate materials are arranged, and a joint fitting such as a nail is driven in, so that the wall magnification is 4. 01 and high earthquake resistance. However, there is a problem in that the design is lacking because it is attached to the plate material in a state in which the crosspiece protrudes, and the joint fitting such as a nail is exposed on the opposite side. In addition, since the pier is attached to the plate material only with an adhesive, there is a problem that it lacks durability.

  Furthermore, although the technique described in Non-Patent Document 1 is excellent in earthquake resistance similarly to the technique described in Patent Document 5, the pillars are exposed on one side and nails and the like are exposed on the opposite side. There is a problem that it lacks design properties.

  The present invention was devised in view of the above circumstances, and provides a plate-wall bearing wall that is excellent in design like a dropped plate wall, has better workability than a conventional dropped plate wall, and has improved earthquake resistance. It is an object.

The plate wall bearing wall according to the present invention includes a column that is erected vertically with respect to the base, and a recess that forms a wall that is attached between the columns and that is continuous between the columns. A plurality of horizontally long plate members, a fitting reinforcing member that fits into a groove formed by a concave portion of the plate member, and a horizontal frame that connects the upper ends of the columns and is parallel to the base. And a reinforcing plate that covers the groove into which the fitting reinforcing member is fitted and is attached to the plate member.

Another plate wall bearing wall according to the present invention is a panel material formed by combining a column erected vertically with respect to the base, and a plurality of horizontally long plate members attached between the columns, and the panel material. A fitting reinforcing member that fits into the formed groove; and a reinforcing plate that covers the groove into which the fitting reinforcing member is fitted and is attached to the plate member. The groove is formed on a plurality of plate members. The formed recessed part is comprised continuously .

Still another plate wall bearing wall according to the present invention is a column that stands vertically with respect to the base, and a groove that is attached between the columns to form a wall and that is connected between the columns. A plurality of horizontally long plate members having recesses formed therein, a fitting reinforcement member fitted into a groove formed by the depressions of the plate material, and covering the groove in which the fitting reinforcement member is fitted; In the load-bearing wall having a reinforcing plate attached to a slanted reinforcing plate member, an oblique reinforcing plate member intersecting in an X shape is further attached .

  In the plate wall bearing wall according to the present invention, since the fitting reinforcing member is fitted into the groove formed of the concave portion of the plate material, it is possible to ensure higher earthquake resistance than the conventional dropped plate wall. In addition, since the nail or the like is not exposed unlike the conventional improved version, the design property of the dropped plate wall does not deteriorate at all.

  Further, it is not necessary to drop the plate materials one by one from the upper side as in the case of a conventional dropped plate wall, and the plate material is attached from the lateral direction, and is then held down and fixed by a frame member, so that the workability is greatly improved.

The plate-wall bearing wall according to the embodiment of the present invention is configured, for example, as shown in FIG. 1, with two columns 100 erected perpendicularly to the base 400 and attached between the columns 100. Then, a plurality of horizontally long plate members 200 formed with recesses 210 to be grooves 250 connected in a state of being attached between the pillars 100, and a groove 250 formed by the recesses 210 of the plate members 200. It has a joint reinforcing member 300 and a horizontal member 500 that connects the upper ends of the pillars 100 and is parallel to the base 400.
The fitting reinforcing member 300 is not visible because it is located on the back side of the reinforcing plate 600, but is shown by a dotted line in FIG.

  As shown in FIG. 1 and the like, the pillars 100 are erected on a base 400 in parallel with each other, that is, vertically with respect to the base 400. One side groove 110 is formed on the side face of the pillar 100 facing the adjacent pillar 100 as shown in FIG. The one-side groove 110 is formed by cutting out one corner of a quadrangular prism and making it substantially L-shaped in plan view. The cut width of the one-side groove 110 is 1 mm to 1/2 of the difference between the length dimension of the plate material 200 and the dimension between the columns 100 so that the plate material 200 can be attached between the columns 100. It is set by adding the gap. Further, the cutting depth of the one-side groove 110 is set larger than the sum of the thickness dimension of the plate member 200 and the thickness dimension of a reinforcing plate 600 described later.

The mounting of the plate member 200 between the pillars 100 is performed by positioning the lower side of the lowermost plate member 200 in the base groove 410 formed in the base 400 and both ends of the lowermost plate member 200 in the one-side groove 110 of the column 100, Furthermore, it is performed by stacking the plate material 200 on the upper side. When all the plate members 200 are stacked and the upper side of the uppermost plate member 200 is fitted into the upper groove 510 of the horizontal member 500, both ends of each plate member 200 positioned in the one-side groove 100 are connected to the side surface of the column 100. Fixing is completed by being sandwiched between the one-side groove 110 by the frame member 150 attached to the frame.
Note that the uppermost plate member 200 is narrower than the other plate members 200.

  The uppermost plate member 200 is fixed to the upper groove 510 by the frame member 150U.

  Further, convex portions are formed at the upper end and the lower end of the pillar 100. The convex portion at the lower end is a portion inserted into the hole of the base 400, and the convex portion at the upper end is a portion inserted into a hole in the horizontal member 500 described later. Such columns 100 are erected in parallel with the one-side grooves 110 facing each other.

  The horizontal member 500 connects the upper ends of the pillars 100, and a hole into which the convex part at the upper end of the pillars 100 is inserted. When the horizontal member 500 is attached to the upper end of the column 100, the column 100 is orthogonal to the column 100 and is parallel to the base 400.

  The plate member 200 is formed in a horizontally long rectangular shape, and a ridge 220 is formed on one of the long sides and a concave groove 230 is formed on the other of the long sides corresponding to the ridge 220. Accordingly, when the plate member 200 is laminated with the longitudinal sides thereof in the horizontal direction, the sap 220 and the concave groove 230 are fitted and sunk together.

  As shown in FIG. 5 and the like, three concave portions 210 are formed in the plate material 200 at equal intervals. The recesses 210 form three vertical grooves 250 parallel to the pillars 100 when the plate member 200 is fitted between the pillars 100. The concave portion 210 is formed at a center portion and an end portion in the longitudinal direction of the plate material 200 so as to be perpendicular to the longitudinal side of the plate material 200.

The fitting reinforcement member 300 is fitted into a vertical groove 250 formed by the recess 210. The length dimension of the fitting reinforcing member 300 is set equal to the height dimension of the wall, that is, the dimension between the base 400 and the horizontal member 500. However, the fitting reinforcing member 300 can be divided into several pieces. Further, since the fitting reinforcing member 300 is fitted into the longitudinal groove 250, the width dimension is set to be the same as the width dimension of the groove 250, and the thickness dimension is set to be the same as the depth dimension of the groove 250. Yes.
For this reason, the fitting reinforcing member 300 is fitted into the groove 250 exactly.

  The fitting reinforcing member 300 is fitted into the groove 250 in a state where the plurality of plate members 200 are attached between the columns 100. That is, after the plurality of plate members 200 are positioned between the pillars 100, the frame member 150 is attached to the pillars 100 and the plate members 200 are fixed between the pillars 100.

  In a state where the fitting reinforcing member 300 is fitted in the groove 250, the reinforcing plate 600 is attached to the plate member 200 so as to hide the fitting reinforcing member 300. The reinforcing plate 600 is attached to the plate member 200 by driving a joint fitting 610 such as a nail toward the plate member 200 from the reinforcing plate 600 side.

The test body A (see FIG. 1) having the above-described three fitting reinforcing members 300 and covering each of the fitting reinforcing members 300 with the reinforcing plate 600, and the test body A further intersected in an X shape. A test body B (see FIG. 2) in which two diagonal reinforcing plates 700 are arranged side by side and attached to the plate material 200, and only one oblique type reinforcing plate 700 that intersects the test body A in an X shape is attached to the plate material 200. The body C (FIG. 3) was comprised and the test about the seismic performance was done about each.
Note that in the test body C, at the intersection between the reinforcing plate 600 and the oblique reinforcing plate 700, the intersecting portion of the reinforcing plate 600 is cut out, and the oblique reinforcing plate 700 is notched.

  The two pillars 100 and the base 400 were made of 105 mm square cedar, and the horizontal member 500 was made of cedar having a width of 105 mm and a thickness of 180 mm. Moreover, the board | plate material 200 used the cedar book processing material of width 150mm and thickness 30mm. Further, a 21 mm square cedar reinforced LVL material (LVL means a material in which veneers are aligned and aligned (Laminated Veneer Lumber)) was used for the fitting reinforcing member 300.

  Furthermore, the column 100 and the base 400, and the column 100 and the horizontal member 500 were joined to each other by a long tenon using a 20 mm diameter insert plug of a cedar reinforced LVLL material. As for the dimensions of the plate bearing wall, the width dimension (interval between the columns 100) was 1820 mm, and the height dimension (interval between the base 400 and the horizontal member 500) was 2730 mm.

The horizontal loading test of the plate wall bearing wall was performed in accordance with a standard test method.
As shown in FIG. 10, each specimen A, B, and C is installed with a tie rod type to prevent the pillars 100 from being lifted by using tie rods at the pillars 100 on both sides, and two places on the base 400 are bolts. It was fixed to the test apparatus with a washer.
The method of applying force is positive and negative alternating force, and the positive and negative deformations with an apparent deformation angle of 1/600 rad, 1/450 rad, 1/300 rad, 1/200 rad, 1/150 rad, 1/100 rad, 1/75 rad, 1/50 rad Occasionally, each was repeatedly applied three times and then destroyed with a force in the compression direction.
The load speed was 30 mm / min.
The horizontal displacement of the horizontal member 400 was measured with a strain gauge type wire displacement meter S1 having an accuracy of 1/20 mm, and the horizontal displacement of the base was measured with a strain gauge type displacement meter S2 having a accuracy of 1/500 mm.
The vertical displacement was measured at two locations on the left and right pillars 100 and at both ends of the base 400 using a strain gauge displacement meter S3 with an accuracy of 1/200 mm.
The load was measured with a load cell S4 having an accuracy of 1/100 kN.
The above measurement was performed at a 1-second interval using a data logger.

7, 8 and 9 show the load-shear deformation angle curves of the test specimens A, B and C, respectively. Using these data, the short-term shear strength and wall magnification of the plate-wall bearing wall shown in Table 1 were determined. Here, short-term shear strength was calculated using the following equations.
Maximum load: Maximum load x 2/3
Yield strength: Yield strength Ultimate strength: Ultimate strength x 0.2 / Ds (where Ds: structural characteristic coefficient)
Specific proof stress: proof strength when the true deformation angle is 1/150 rad The wall magnification was obtained by dividing the minimum value of the short-term shear strength by the coefficient (= 1.96) and the wall length (= 1.82 m).

As shown in Table 1, in the specimen A having only the fitting reinforcing member 300, the wall magnification is 0.95, which is 1.6 times the wall magnification 0.6 of the dropped plate wall described in the Ministry of Construction Notification No. 1100. became. In the test body B in which two diagonal reinforcing plates 700 crossing in an X shape are arranged on the test body A and attached to the plate material 200, the wall magnification is 1.68, which is 2.8 times the plate wall of the notice. Further, in the test body C in which one diagonal reinforcing plate 700 crossing the test body A in an X-shape is attached to the plate material 200, the wall magnification is 4.26, which is 7.1 times that of the noticed plate wall. .
From these, it was confirmed that the plate wall bearing wall of the present invention has extremely excellent earthquake resistance.

In the test bodies A to C described above, cedar materials are used for the two pillars 100, the base 400, and the horizontal member 500, but wood such as cypress materials may be used. Further, although the reinforcing plate 600 and the oblique reinforcing plate 700 are made of cedar, they may be made of wood such as cypress or synthetic resin.
Moreover, although the cedar reinforcement | strengthening LVL material was used for the fitting reinforcement member 300 or a bayonet, wood with high density, such as a scarf material, may be sufficient.
Further, the plate material 200 used for the above-described test bodies A to C was sane-processed so as to be sunk, but has an upward triangular mountain-shaped convex portion and a downward triangular valley. It may be combined with the mold recess, or may be flat.

  Furthermore, in the above-described embodiment, the fitting reinforcing member 300 and the reinforcing plate 600 that covers the fitting reinforcing member 300 are separated from each other. However, as shown in FIG. 11, the reinforcing convex portion 810 that fits into the groove 250, It is also possible to use an integrated fitting reinforcing member 800 in which a reinforcing portion 820 that is larger than the reinforcing convex portion 810 and attached to the plate member 200 is integrated.

  When this integrated fitting reinforcing member 800 is used, the two steps of attaching the reinforcing plate 600 after attaching the fitting reinforcing member 300 become one step of attaching the integrated fitting reinforcing member 800. There is a merit that the performance is improved.

Further, in the above-described embodiment, a plurality of plate members 200 constituting the wall are described as being attached between the pillars 100 in the field. However, in a factory or the like, the plurality of plate members 200 are used as a single or divided panel material. It is also possible.
In this case, one panel material is obtained by attaching the fitting reinforcing member 300 to the groove 250 formed of the concave portion 210 formed in the plate material 200.
Thus, if the board | plate material 200 is previously made into a panel material before the field, an improvement of workability | operativity can be aimed at.

Furthermore, although only the wall has been described in the above-described embodiment, it is also possible to configure a plate bearing floor by positioning the plate member 200 on a plane.
In this case, the plate load-bearing floor is configured between a horizontal member provided in parallel and horizontally and a horizontal member provided orthogonally and horizontally to form a floor. It has a plurality of horizontally long plate members in which concave portions that become continuous grooves in the attached state are formed, and a fitting reinforcing member that fits into a groove constituted by the concave portions of the plate material.
