Description

  The present invention relates to a method for connecting panels used on a wall of a house.

  2. Description of the Related Art Conventionally, a panel construction method has been adopted in which components such as walls of a house are panelized in a factory in advance, and these panels are assembled at a construction site to construct a house. This panel method has the advantage that the construction is simple and the construction period is short.

  In the panel construction method, a panel having excellent heat insulating properties, which is configured by sandwiching a heat insulating material between two face materials, is used. For example, a panel used as a wall panel of a house is configured by filling a wooden frame body formed in a rectangular frame shape with a heat insulating material, and attaching face materials such as plywood on both front and back surfaces of the frame body ( For example, see Patent Document 1).

  When connecting the wall panel at a construction site, the side end surfaces of the frame members of adjacent wall panels are brought into contact with each other, the corresponding contact portion is adhered with an adhesive, and the other side is passed through the frame material from one wall panel. This is done by driving nails into the frame of the wall panel.

Japanese Patent Laid-Open No. 9-4126

  However, in the case of a panel configured by attaching face materials to both the front and back sides of the frame body, there is no heat insulating material at the connection portion because there is a frame body at the connection portion of the panel, and the width direction of the connected panel In this case, there is a problem that the heat insulating material is completely interrupted at the connection portion position, and the heat insulation performance of the connection portion is remarkably deteriorated.

  Also, when connecting panels, it is necessary to drive a nail at a fine nail pitch using a large number of nails, and to nail the panel diagonally from one wall panel to the other. There is a problem that it takes time to drive the nail because it is necessary to drive the nail carefully. Therefore, it takes time to connect the panels.

  Then, the subject of this invention is providing the connection method of the panel which can perform the connection of panels easily, without reducing heat insulation performance.

  In order to solve the above-described problems, the panel connection method of the present invention is a rectangular panel connection method including only a core material made of a heat insulating material and a face material attached to both surfaces of the core material. A semicircular hole is provided at the center of the width direction end of the panel, the side end surfaces of adjacent panels are brought into contact with each other, and the semicircular holes of the adjacent panels are combined to form a circular hole. Then, while inserting a cylindrical pin member into the circular hole, and arranging a connecting bracket so as to straddle between adjacent panels at the corner of the panel, connecting both panels via the connecting bracket, Fixing metal fittings are arranged at the four corners of the connected panels, and the panels are fixed to members adjacent to the upper and lower sides of the panel via the fixing metal fittings.

  In addition, the panel connection method of the present invention provides a half-divided hole at the center position of the widthwise end of the panel, and abuts the side end surfaces of adjacent panels so that the half-divided angle of the adjacent panels. A square hole is formed by combining the holes, and a prismatic pin member is inserted into the square hole, and a connecting metal fitting is disposed so as to straddle between adjacent panels at the corner of the panel, Both panels are connected via the connecting metal fittings, fixing metal fittings are arranged at the four corners of the connected panels, and the panels are fixed to adjacent members above and below the panel via the fixing metal fittings.

  The connection fitting is formed of a U-shaped member, and the U-shaped member is fitted so as to straddle between adjacent panels at the upper and lower end surface positions of the panel corners. It is characterized in that a bolt is inserted through and connected to a bolt hole provided in a letter-shaped member.

  According to said structure, it is not the method of connecting panels through a frame body, but directly connects the panels comprised only of the face material stuck to both surfaces of the core material which consists of heat insulating materials, and a core material. Therefore, the heat insulating material is not interrupted at the connecting portion position in the width direction of the connected panel, and the heat insulating performance of the connecting portion is not deteriorated.

  In addition, since the panel can be connected with a connecting member that is arranged so as to straddle between adjacent panels and the pin member, it is not necessary to drive a large number of nails obliquely from the outside of each panel, and the labor is dramatically increased. Can be reduced. As a result, the panels can be easily connected to each other.

  The fixing bracket is formed of an L-shaped member having two flat plate portions connected so as to form a right angle. One flat plate portion has a long hole and the other flat plate portion has a circular hole. In the four corners of the connected panel, the flat plate portion on which the circular hole is provided is brought into contact with the face material surface of the panel to be bolted to the face material, and the other elongated hole is provided. L-shaped members are arranged from both sides of the panel so that the flat plate portion is located on the upper and lower surfaces of the panel, and the long holes of the flat plate portions of the two L-shaped members are overlapped on the upper and lower surfaces of the panel The bolts are inserted into the long holes in the combined state and fixed to members adjacent to the upper and lower sides of the panel through the bolts inserted through the long holes.

  According to the above-described fixing bracket, the cross-sectional L-shaped member is disposed from both sides of the panel, and the long holes of the flat plate portions of the two cross-sectional L-shaped members are overlapped on the upper and lower surface sides of the panel. Since it is set as the structure which penetrates a volt | bolt and fixes to the member adjacent to a panel upper and lower sides, it can apply a fixing bracket to the panel of various thickness.

  As described above, according to the panel connection method according to the present invention, it is possible to directly connect panels composed of only a core material made of a heat insulating material and a face material attached to both surfaces of the core material. And the heat insulation performance of a connection part is not reduced, and the connection of panels can also be performed easily.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view showing a panel provided with a semicircular hole used in the present invention, and FIG. 2 is a front view showing a connection state of the panel provided with a semicircular hole used in the present invention. . As shown in FIG. 1, the panel 1 used in the present invention is configured by attaching face materials 3 and 3 to both surfaces of a core material 2 made of a rectangular heat insulating material. FIG. 2 shows a front view when two panels 1a and 1b are connected.

  The heat insulating material used for the core material 2 is made of a foamed resin such as polyurethane foam or polystyrene foam. In the present invention, any resin foam may be used, but a heat insulating material made of expanded polystyrene having excellent processability is particularly preferable.

  The face materials 3 and 3 adhered to both surfaces of the core material 2 are made of wood panels such as plywood, particle board, or oriented strand board. The panel 1 is configured by adhering face materials 3 and 3 to both surfaces of a core material 2 made of a heat insulating material, and a method of adhering using an adhesive is generally used as the adhering method.

  As shown in FIG. 2, when two panels 1a and 1b are connected, semicircular holes 4a and 4b are provided at the center position of one end in the width direction of each panel 1a and 1b. When the side end surfaces of the adjacent panels 1a and 1b where the semicircular holes 4a and 4b are provided are brought into contact with each other, the semicircular hole 4a of one panel 1a and the other panel A circular hole 5 is formed by combining the semicircular holes 4b of 1b.

  A cylindrical pin member 6 shown in FIG. 3 is inserted into the circular hole 5. The diameter and material of the cylindrical pin member 6 are selected according to the load acting on the pin member 6. The pin member 6 is made of a wooden or steel member such as hardwood. Therefore, the diameter of the circular hole 5 is determined according to the diameter of the cylindrical pin member 6 to be inserted. Further, the length of the cylindrical pin member 6 is the same as the thickness of the panel 1.

  In addition, the hole 4 provided in the center position of the one edge part of the width direction of the said panel 1 is a half quadrangle or a half hexagon half split angle as shown to (a) to (c) of FIG. The holes 7, 8, 9 may be used. For example, when connecting the two panels 1a and 1b provided with the half-square holes 7a and 7b shown in FIG. 4A, as shown in FIG. 5, the half-square shape of the adjacent panels 1a and 1b is used. When the side end surfaces on which the holes 7a and 7b are provided are brought into contact with each other, the half square hole 7a of one panel 1a and the half square hole 7b of the other panel 1b are aligned. Thus, a square hole 10 is formed.

  A square columnar pin member 11 a shown in FIG. 6A is inserted into the square hole 10. The square pillar-shaped pin member 11a has a cross-sectional size and material selected according to the load acting on the pin member 11a. As the pin member 11a, a wooden or steel member such as a hardwood is used. Therefore, the size of the square hole 10 is determined according to the shape of the quadrangular columnar pin member 11a to be inserted. Further, the length of the quadrangular columnar pin member 11 a is the same as the thickness of the panel 1.

  In addition, when connecting the two panels 1 which provided the half square hole 8 shown in FIG.4 (b), the square-column-shaped pin member 11b shown in FIG.6 (b) is inserted. Moreover, when connecting the two panels 1 which provided the half-hexagonal hole 9 shown in FIG.4 (c), the hexagonal column-shaped pin member 11c shown in FIG.6 (c) is inserted. Similarly to the square columnar pin member 11a shown in FIG. 6 (a), the square columnar pin member 11b shown in FIG. 6 (b) and the hexagonal column shaped pin member 11c shown in FIG. 6 (c) are also pin members. The cross-sectional size and material are selected according to the load acting on 11b and 11c. As the prismatic pin members 11b and 11c as shown in FIGS. 6B and 6C, wooden or steel members such as hardwood are used. Therefore, the size of the square hole into which the prismatic pin members 11b and 11c are inserted is determined according to the shape of the prismatic pin members 11b and 11c to be inserted. The prismatic pin members 11b and 11c are formed to have the same length as the panel 1 in length.

  When three or more panels 1a, 1b, and 1c are connected, as shown in FIG. 7, a panel 1b (hereinafter referred to as an intermediate panel) to which adjacent panels 1a and 1c are connected to both side end faces Semicircular holes 4b and 4c are provided at the center positions at both ends of the panel 1b in the width direction. Then, when the side end surfaces of the adjacent panels 1a and 1c where the semicircular holes 4a and 4d are provided are brought into contact with both end surfaces of the intermediate panel 1b, the semicircular holes of one panel 1a 4a and one semicircular hole 4b of the intermediate panel 1b are combined to form a circular hole 5a, and the semicircular hole 4d of the other panel 1c and the other semicircular shape of the intermediate panel 1b. These holes 4c are combined to form a circular hole 5b. A cylindrical pin member 6 shown in FIG. 3 is inserted into each of the circular holes 5a and 5b.

  In FIG. 7, the case where the semicircular holes 4b and 4c are provided at the center positions at both ends in the width direction of the intermediate panel 1b has been described. However, the shape of the hole is changed from a semicircular shape to (a) in FIG. As shown in c), it may be a half-square hole or a half-hexagonal hole 7, 8, 9 as shown in c). For example, as shown in FIG. 8, when the half-square holes 7b and 7c shown in FIG. 4 (a) are provided at the center positions at both ends in the width direction of the intermediate panel 1b, it is adjacent to both end faces of the intermediate panel 1b. When the side end surfaces of the matching panels 1a and 1c where the half-square holes 7a and 7d are provided are brought into contact, the half-square holes 7a of one panel 1a and one half of the intermediate panel 1b The square hole 5c is formed by combining the split square hole 7b, and the half square hole 7d of the other panel 1c and the other half square hole 7c of the intermediate panel 1b are combined. A square hole 5d is formed. A square columnar pin member 11a shown in FIG. 6A is inserted into each of the square holes 5c and 5d.

  When the half square holes 8 shown in FIG. 4B are provided at the center positions at both ends in the width direction of the intermediate panel 1b to connect the panels 1a, 1b, and 1c, they are shown in FIG. 6B. A square columnar pin member 11b is inserted. When the half hexagonal holes 9 shown in FIG. 4 (c) are provided at the center positions at both ends in the width direction of the intermediate panel 1b to connect the panels 1a, 1b, and 1c, they are shown in FIG. 6 (c). A hexagonal columnar pin member 11c is inserted.

  As shown in FIGS. 2, 5, 7, and 8, a connecting metal fitting 12 is disposed so as to straddle between adjacent panels at the panel upper and lower end surface positions at the corners of the panel. Adjacent panels 1a, 1b, 1c are connected.

  As shown in FIG. 9, the connecting fitting 12 is formed of a steel member having a U-shaped cross section, and is provided with a bolt hole 13. As shown in FIG. 10, the connecting metal 12 fits the panels 1 a and 1 b into the concave portions having a U-shaped cross section so as to straddle between the adjacent panels 1 a and 1 b at the panel upper and lower end surface positions at the corners of the panel 1. Adjacent panels 1a and 1b are connected by inserting bolts into the bolt holes 13 provided in the connecting metal fitting 12 so as to penetrate the panels 1a and 1b.

  As shown in FIGS. 2, 5, 7, and 8, fixing brackets 14 are arranged at the four corners of the connected panels, and the panel 1 is attached to a member 15 adjacent to the upper and lower sides of the panel via the fixing brackets 14. Is fixed.

  As shown in FIG. 11, the fixing bracket 14 is formed of an L-shaped member having two flat plate portions 16a and 16b connected so as to form a right angle. One flat plate portion 16b is provided with a circular hole 18.

  As shown in FIG. 12, the fixing brackets 14a, 14b, 14c, and 14d are connected to the flat plate portion 16b provided with the circular holes 18 at the four corners of the connected panels 1a, 1b, and 1c. A cross section L from both sides of the panel 1 so that the flat plate portion 16a, which is in contact with the material surface and is bolted to the face materials 3 and 3 and the other long hole 17 is provided, is located on the upper and lower surfaces of the panel. A character-shaped member is arranged.

  As shown in FIGS. 12 to 14, after arranging the L-shaped members from both sides of the panel 1, the long holes 17 a of the flat plate portions 16 a and 16 a of the two L-shaped members on the upper and lower surface sides of the panel 1. In a state where 17b is overlapped, a bolt 19 is inserted into the long holes 17a and 17b, and is fixed to a member 15 adjacent to the top and bottom of the panel via the bolt 19 inserted into the long holes 17a and 17b. Thereby, the connected panels 1a, 1b, and 1c are fixed to the members 15 adjacent to the upper and lower sides of the panel.

  According to the fixing bracket 14 described above, L-shaped members are arranged from both sides of the panel 1, and the long holes 17a, 17b of the flat plate portions 16a, 16a of the two L-shaped members are arranged on the upper and lower surfaces of the panel. Since the bolts 19 are inserted into the elongated holes 17a and 17b in a superposed state, the elongated holes 17a and 17b of the two flat plate portions 16a and 16a are formed according to the thickness of the panel 1 to be used. By adjusting the overlap amount, a hole having a size that allows the bolt 19 to be inserted can be formed. Therefore, the fixture 14 can be arranged on the panel 1 having various thicknesses.

  The bolt joint between the flat plate portion 16b provided with the circular hole 18 and the face material 3 is performed by inserting the bolt 21 from the outer surface side of the flat plate portion 16b into the circular hole 18 using a one-side bolt or the like. The material 3 is fixed so as to penetrate. In consideration of the strength of the face material 3, a plate-like reinforcing plate 20 may be provided between the face material 3 and the core material 2. In this case, a notch is formed in the core material 2 to such an extent that the reinforcing plate 20 can be inserted, and the reinforcing plate 20 is inserted into the notch.

  Although not shown, the fixing bracket 14 can be used not only to connect the connected panels 1 but also to fix only one panel 1 to the members 15 adjacent to the upper and lower panels.

  Next, the state of the load generated between the panel connections when a horizontal load due to wind, earthquake, or the like acts on the connected panels will be described. FIG. 15 shows the state of the load generated between the panel connections when the pin member is not used, and FIG. 16 shows the state of the load generated between the panel connections when the pin member is inserted. In FIG. 16, as an example, semicircular holes 4a and 4b are provided at the center position of one end in the width direction of each panel 1a and 1b to be connected, and a cylindrical pin member 6 is inserted. explain.

  First, in the case of the panels 1a and 1b connected without using the pin member 6, as shown in FIG. 15, when a horizontal load P (from left to right in FIG. 15) is applied due to wind, earthquake, or the like. The bolt position 22 and the bolt position 23 serve as pin fulcrums, and the panels 1a and 1b tend to tilt to the right in FIG. At this time, loads Q1 and Q2 in the direction of the arrow in FIG. 15 are generated between the panels 1a and 1b. The loads Q1 and Q2 act so as to generate a shift between the connected panels 1a and 1b.

  On the other hand, in the case of the panels 1a and 1b connected by inserting the pin member 6, the load Q1, when the inserted pin member 6 resists the loads Q1 and Q2 generated between the panel connections. Misalignment between the connected panels 1a and 1b due to Q2 can be prevented. That is, when the pin member 6 prevents the one panel 1a and the other panel 1b from moving separately, the connected panels 1a and 1b move together and are connected. The yield strength of the panels 1a and 1b can be improved.

  According to the above-described panel connection method, the panels are not connected to each other through the frame body, but only by the face materials 3 and 3 adhered to both surfaces of the core material 2 and the core material 2 made of a heat insulating material. Since the constructed panels can be directly connected to each other, the heat insulating material is not interrupted at the connecting portion position in the width direction of the connected panels 1, and the heat insulating performance of the connecting portion is not deteriorated.

  Further, since the panel 1 can be connected with the pin members 6 and 11 and the connecting fitting 12 arranged so as to straddle between adjacent panels, it is not necessary to drive a large number of nails obliquely from the outside of each panel 1. The time and effort can be drastically reduced. Thereby, connection of panels can be performed easily.

  Moreover, although not shown in figure, an airtight sheet | seat may be affixed on the outer side of the face materials 3 and 3 of a panel connection part as needed.
