BACKGROUND OF THE INVENTION
The present invention relates to a beam receiving structure that is constructed by a panel method and is applied to a building in which beams are attached to a wall panel substantially orthogonally.
[0002]
[Prior art]
In recent years, the industrialization of housing has also progressed, and some so-called panel construction methods, such as building a building by assembling these panels at the construction site, for example, building structures such as floors, walls, and roofs in advance at the factory. Adopted and implemented.
[0003]
As a structure obtained by such a panel method, for example, a structure as shown in FIGS. 3 and 4 is known for the receiving part of the wall and the beam for laying the beam substantially orthogonal to the wall surface. Yes. In this structure, a pair of wall panels 41 composed of a core material 41a assembled in a rectangular frame shape and a surface material 41b attached to both surfaces thereof are in a state where the core materials 41a at the respective side end portions are abutted with each other. The wall body 40 is formed by joining.
[0004]
A reinforcing plywood 50 is attached to the wall surface 40 a of the wall body 40 so as to cross the joint portion 42 of the pair of wall panels 41. The reinforcing plywood 50 is formed in a long rectangular parallelepiped shape, and is disposed on the upper surface of the wall surface 40a so that the length direction thereof is substantially parallel to the upper end of the wall body 40, and is attached by a number of nails and adhesives. Yes. The beam receiver 60 is attached to the reinforcing plywood 50, and the end of the beam 30 is supported by the beam receiver 60.
[0005]
Here, the beam receiver 60 includes a rectangular contact piece 61 that contacts the front surface of the reinforcing plywood 50, a side piece 62 that extends from both side edges of the contact piece 61 to the opposite side of the reinforcing plywood 50, and The mounting piece 63 extends from the lower edge of the contact piece 61 to the opposite side of the reinforcing plywood 50 at a substantially right angle, and the mounting piece 64 extends from the upper end of the contact piece 61 toward the reinforcing plywood 50. The mounting piece 64 is fixed to the reinforcing plywood 50 by nailing or the like while being placed on the upper surface of the reinforcing plywood 50.
[0006]
Further, the end of the beam 30 is notched in, for example, a substantially inverted L shape when viewed from the side, and the upper side protrudes from the lower side, and the upper side is mounted on the mounting piece 63 of the beam receiver 60. The upper end surface of the wall body 40 and the upper surface of the beam 30 are bridged so as to be substantially orthogonal to the wall surface 40a.
[0007]
[Problems to be solved by the invention]
As described above, in the conventional beam receiving structure, since the beam is received only by the beam receiving metal, the reinforcing plywood for attaching the beam receiving metal is formed long so that it can be attached with high strength, and the wall surface is formed by a number of nails while using an adhesive. Is attached. However, since the width of the core material is not so thick in a normal wall panel, only a few nails are struck against the core material among the many nails used for attaching the reinforcing plywood. Therefore, the actual situation is that the reinforcing plywood is attached to the wall of the wall body composed of the wall panel by surface bonding, and as a result, the beam receiving structure has a problem that the durable strength is unstable.
[0008]
Moreover, since the reinforcing plywood is substantially attached to the wall surface by surface bonding, the attachment strength varies depending on the type of adhesive, and the attachment strength varies depending on the number of nails struck against the core material. There is also a problem that a beam receiving structure having a constant strength cannot be obtained. Further, since a reinforcing plywood, a nail for attaching the reinforcing plywood, and an adhesive are necessary for mounting the beam receiving metal, there is a problem that a large number of parts are required.
[0009]
[Means for Solving the Problems]
Therefore, in the beam receiving structure according to the present invention for solving the above-described problem, a pair of wall panels each having a face material provided on both sides of a core material assembled in a rectangular frame shape are core materials at the respective side end portions. A wall body joined in a state of being faced to each other, a beam receiver attached to a joint portion of a pair of wall panels of the wall body, and substantially orthogonal to the wall surface via the beam receiver The wall body is substantially L-shaped in a side view having a lower end surface at a position opposite to the core material of the side end portion of each of the pair of wall panels . it the result is hardware receiving slits formed having a bottom made of extraordinary seen the lower end face to the outside from the wall surface of the beam side to the joint portion cutout portion is provided, the beam receiving hardware is beamed wall Placed in contact with the side wall and across the joint. A hardware main body for supporting the ends of the beam is a pair of fixing pieces fixed to the core material of the side edge portions of each pair of wall panels provided on both sides of the hardware main body, the wall side of the hardware main body The surface is formed of an insertion piece that extends toward the hardware receiving slit and is inserted into the hardware receiving slit.
[0010]
In the present invention, the metal receiving slit is formed in the joint portion of the pair of wall panels by providing the notch portions at the opposing positions of the core members of the side end portions in each of the pair of wall panels. The insertion piece of the beam receiving metal object inserted into the metal object receiving slit is placed and supported on the bottom portion made of the core material at the side end portions of both of the pair of wall panels in the metal object receiving slit. Further, since the pair of fixing pieces provided on both sides of the hardware main body are fixed to the cores at the side ends of the pair of wall panels, the beam receiving hardware is composed of the insertion piece and the pair of fixing pieces. It is in the state supported by the core material of the side edge part of a wall panel. Therefore, since the beam receiver is always firmly attached to the wall body with a constant strength, a beam receiver structure with a stable durable strength is realized. In addition, the number of parts can be reduced because the beam receiving hardware is firmly attached to the wall body without using the conventional auxiliary plywood and the adhesive and nails necessary for attaching the auxiliary plywood.

It is prepared for.
[0013]
The pair of wall panels 11 and 11 constituting the wall body 10 are each formed by providing a face material 11b such as a plywood on both surfaces of a core material 11a assembled in a rectangular frame shape, and a core material 11a at a side end. It is joined in a state where they are abutted. The core member 11a at the side end is formed to have a width that allows a fixing piece (described later) of the beam receiver 20 to be fixed by nailing. Further, the wall body 10 is formed with a hardware receiving slit 13 facing the outside from the wall surface 10a on the beam 30 side in the joint portion 12 of the pair of wall panels 11 and 11. At this time, the hardware receiving slit 13 is formed by providing a notch portion 13a at a position where the core material 11a of each side end portion of the joint portion 12 of the pair of wall panels 11 and 11 is opposed to each other. .
[0014]
That is, at the side end surface of the side end portion where the pair of wall panels 11 and 11 are joined and at the position where the beam 30 is attached when the wall body 10 is configured, the lower part joined in a state of being in contact with each other. A cutout portion 13a is formed in a state in which a core material 11a having a predetermined thickness is cut out in the width direction of the wall panel 11 from the surface. For this reason, the cutout portion 13a is formed in a substantially L shape in a side view from a side surface made of the core material 11a and a lower end surface made of the core material 11a and having a predetermined thickness. Therefore, in the state in which the pair of wall panels 11 and 11 are joined, the joint portion 12 has the bottom portion 13a ₁ composed of the lower end surfaces of the two cutout portions 13a and 13a, and from the wall surface 10a on the beam 30 side. A hardware receiving slit 13 facing the outside is formed.
[0015]
In the present embodiment, the hardware receiving slit 13 is formed to have a width slightly larger than the thickness of an insertion piece to be described later of the beam receiving hardware 20 and a height dimension substantially equal to the height dimension of the insertion piece. Further, the wall 10 is provided from the upper end.
[0016]
The beam receiving hardware 20 includes a hardware main body 21, a pair of fixed pieces 22, 22 and an insertion piece 23. The metal body 21 supports the end of the beam 30, and has a substantially rectangular contact piece 21 a disposed in contact with the wall surface 10 a of the wall 10 on the beam 30 side and across the joint portion 12. The mounting piece 21b extends substantially perpendicularly from the lower end of the contact piece 21a to the opposite side of the wall body 10, and the side edge 21c is formed to extend from both side edges of the contact piece 21a to the opposite side of the wall surface 10a. ing. In the present embodiment, the contact piece 21a is formed to have a height that is substantially equal to the height of the upper side of the end portion of the beam 30, which will be described later, and is slightly larger than the width of the beam. Moreover, the back surface of the contact piece 21 is bonded to the wall surface 10a with an adhesive.
[0017]
The pair of fixed pieces 22 and 22 are respectively provided on both side edges of the contact piece 21a of the hardware main body 21, and here, extend from the contact piece 21a of the hardware main body 21 along the wall surface 10a of the wall body 10. In this state, it is formed integrally with the contact piece 21a. And each fixed piece 22 and 22 is being fixed to the core material 11a of each side edge part of a pair of wall panels 11 and 11 with a nail drive, an adhesive agent, etc.
[0018]
The insertion piece 23 is formed on the back surface of the contact piece 21 a of the hardware main body 21 and extending from the substantially center position in the width direction of the contact piece 21 a toward the hardware reception slit 13, and is inserted into the hardware reception slit 13. It is provided in the state that was done. At this time, the insertion piece 23 is placed and supported by the bottom portion 13a ₁ made of the core 11a of the hardware receiving slit 13. In the present embodiment, the insertion piece 23 has a substantially rectangular shape with a thickness slightly smaller than the width of the hardware receiving slit 13 and substantially the same height as the hardware receiving slit 13, and is integrated with the contact piece 21 a of the hardware main body 21. Is formed.
[0019]
In the present embodiment, the beam 30 is formed such that an end portion thereof is cut into, for example, a substantially inverted L shape in a side view and the upper side protrudes from the lower side, and the upper side is placed on the beam receiving hardware 20. It is supported in a state of being placed on the piece 21b. As a result, the beam 30 is stretched across the wall surface 10 a so that the upper surface thereof is substantially flush with the upper end surface of the wall body 10.
[0020]
Thus, in the beam receiving structure of the present embodiment, the insertion piece 23 of the beam receiving hardware 20 inserted into the hardware receiving slit 13 is the core of the side end portions of both the pair of wall panels 11 and 11 in the hardware receiving slit 13. It is supported in a state of being placed on the bottom 13a ₁ made of the material 11a. A pair of fixing pieces 22, 22 provided on both sides of the contact piece 21 a of the metal body 21 are fixed to the core material 11 a at the side end of each of the pair of wall panels 11, 11.
[0021]
Therefore, the beam receiver 20 is supported by the core member 11a at the side ends of the pair of wall panels 11, 11 by the insertion piece 23 and the pair of fixed pieces 22, 22, whereby the beam receiver 20 is mounted on the wall. Since it is always firmly attached to the body 10 with a constant strength and the beam 30 is supported by the beam receiving hardware 20, a beam receiving structure with a stable durable strength can be realized.
[0022]
In the panel method, since the wall panel 11 is formed in advance at the factory, the hardware receiving slit 13 is also processed in the factory, so that the hardware receiving slit 13 can be precisely formed. It is also possible to form the wall panel 11 with a larger width than the conventional one so that the pair of fixing pieces 22 and 22 of the beam receiver 20 can be fixed by nailing as the core member 11a. . Therefore, even in any of the construction site, it is supported by being securely mounted on the core member 11a of the bottom portion 13a ₁ of the insert piece 23 is hardware receiving slit 13 of the beam receiving hardware 20, and a pair of fixed to the core member 11a A beam receiving structure in which the pieces 22 and 22 are fixed can be realized.
[0023]
In addition, since the beam support 20 is firmly attached to the wall body 10 without using the conventional auxiliary plywood and the adhesive and nails necessary for attaching the auxiliary plywood, the number of parts corresponding to that is intended to be reduced. Can be simple structure. In addition, the construction process can be simplified because the auxiliary plywood is not required to be attached.
[0024]
Furthermore, in the beam receiving structure of the present embodiment, the beam receiving metal 20 is supported on the core 11a at the side end portions of the pair of wall panels 11 and 11 by the insertion piece 23 and the pair of fixing pieces 22 and 22. Therefore, the expected mounting strength can be obtained reliably. That is, an effect that the mounting strength can be specified at the time of designing is obtained.
[0025]
In the present embodiment, an example in which the insertion piece of the beam receiving metal piece is placed and supported on the core member at the bottom of the hardware receiving slit has been described. However, for example, a hole is previously formed in the insertion piece by an adhesive or the like. If the nail is struck to the core on the side of the hardware receiving slit through this hole, the beam receiving metal supported more firmly by the core is obtained.
[0026]
Further, in this embodiment, the beam receiver that supports only the upper side of the end portion of the beam is used. However, the beam receiver may support the entire end portion of the beam, and the upper side of the end portion may be the wall body. Of course, it may be a beam receiver that supports the lower side of the end portion of the beam placed on the upper end surface.
[0027]
【The invention's effect】
As described above, in the beam receiving structure according to the present invention, the insertion piece of the beam receiving hardware is inserted into the hardware receiving slit formed at the joint portion of the pair of wall panels, and the side ends of the pair of wall panels in the hardware receiving slit. Since the insertion piece is supported by the bottom part made of the core material of the part, and the pair of fixed pieces on both sides of the hardware body are supported by the core material of the side ends of the pair of wall panels, The mounting strength of the hardware to the wall is always constant and high. Therefore, according to the beam receiving structure of the present invention in which the beam is supported by such a beam receiving metal, durable strength can be stabilized. In addition, since the beam bracket is firmly attached to the wall body without using the conventional auxiliary plywood and the adhesive and nails that were necessary to attach it, the number of parts can be reduced, and during construction, The auxiliary plywood attachment work process can be eliminated, and the construction can be simplified.
