Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention mainly relates to a load-bearing panel that is installed within the frame of a wooden-structured house and bears horizontal force, and a building frame structure using the load-bearing panel. It is.

[Conventional technology and issues]

In wooden structures, horizontal forces such as those caused by earthquakes are conventionally often dealt with by placing braces and walls.

However, with conventional wooden structures, in addition to problems with the strength of the wood, the freedom of designing openings and spaces is limited by the use of braces and walls as horizontal load-bearing members, and it is difficult to create units. There were problems such as the large amount of time required and the need for craftsmen with special skills, making mass production difficult.

The present invention provides a new horizontal load-bearing member that can be prefabricated, and by incorporating it into a structural framework, it enables mass production, increases the degree of freedom in design, and streamlines construction and improves quality. It was planned.

[Means to solve the problem]

The architectural load-bearing panel of the present invention is made by joining lattice members in which steel pipes, reinforcing bars, and other rod-shaped members are arranged in a wave pattern on both sides of a central vertical member, and framing the vertical members and lattice members with vertical and horizontal frame members to form a unit. was formed. For the joint between the vertical member and the lattice member, for example, the contact portion of the lattice member to the vertical member may be processed to be flat, and that portion may be fixed with bolts or the like.

Further, in the building framework structure of the present invention, the load-bearing panel units are arranged within a framework formed by upper and lower horizontal members and left and right vertical members that constitute the building framework. Load-bearing panels provide great strength as horizontal load-bearing members, and by distributing multiple load-bearing panels with large wall magnifications within a framework, openings such as doorways and windows can be made wider, allowing greater freedom in design. The degree increases.

〔Example〕

FIG. 1 shows a load-bearing panel 1 as a unit, consisting of vertical members 2 (usually made of wood), lattice members 3, and vertical and horizontal frames 12, 13 surrounding them. The lattice member 3 of this embodiment is made by bending a single steel pipe into a wave shape and making the contact part to the vertical member 2 flat, and is connected to both sides of the vertical member 2 arranged in the center with bolts 4 or the like. , together with the frame members 12 and 13, constitute a planar horizontal load-bearing member. The lattice member 3 and the vertical frame member 12 are joined by, for example, joining the bent portion of the lattice member 3 that contacts the vertical bar member 12 with bolts 4''.

Such a load-bearing panel l is in a unitized state, and the second
As shown in the figure, it is used by being built into a framework surrounded by upper and lower horizontal members 5 such as beams, girders, and foundations, and vertical members 6 such as columns. For installation within a framework, vertical and horizontal frame members 12.
13 can also be directly nailed to the upper and lower horizontal members 5 and vertical members 6. Furthermore, when the vertical member 2 at the center of the load-bearing panel 1 is assembled into the framework, it can be treated similarly to a stud.

FIGS. 3(a) and 3(b) show an example of the joint between the vertical member 2 and the lattice member 3 that constitute the load-bearing panel 1. A plate 8 with bolt holes 7 provided on both sides of the vertical member 2 is shown in FIGS. are fixed with wood screws 9, and a bolt 4 passing through the vertical member 2 is inserted through the washer 10 into the abutting portion of the flat lattice member 3 to join them.

Figures 4(a) and 4(b) show details of the joint between the vertical frame member 12 and the lattice member 3 of the load-bearing panel 1. Since the joint is only on one side, this example is shown in Figure 3(b). In place of the bolt hole 7 in b), a plate 8° having a screw hole 7° is used, and the bolt 4' is screwed into this screw hole 7'.

5 to 8 show an example of how to attach the vertical member 2 of the load-bearing panel 1 and the upper and lower horizontal frame members 13.
and the lattice member 3 are assembled, and on the other hand, with the vertical and horizontal frame members 12 and 13 assembled, the joint hardware 16 is fixed to the lower surface of the upper horizontal frame member 12 and the upper surface of the lower horizontal bar member 12, respectively. It is possible to join with bolts 4 using joining hardware 16.

The joining hardware 16 has a rising portion 17 that sandwiches the end of the vertical member 2 from both sides in the in-plane direction (when the joining hardware 16 is installed downward as in the case of the upper end of the IT member 2, this rising portion 17
7 will hang down), and a guide groove 18 that opens outward from the surface of the load-bearing panel 1 is formed in the upright portion 817.

Figures 6(a) and (b) show the connection to the upper horizontal bar 12 of the vertical member 2, and Figures 7(a) to (C) show the joint to the lower horizontal bar 12 of the vertical member 2. This shows the details of the joint, joining hardware 1
6 has its flat base abutted against the horizontal bar 12 and fixed with wood screws 9. The rising edge B17 of the joining hardware 16 is in contact with the upper and lower end side surfaces of the vertical member 2, and the lower end flat portion of the lattice member 3 is in contact with the outside thereof, and is fixed by a bolt 4 passing through these. In the figure, 4a is a nut.

By forming the guide groove 18 in the joining hardware 16, when joining the vertical member 2 and the lattice member 3 to the framed frame member 12.13, as shown in FIG. The rising part 17 of the joining hardware 16 can be slid between the vertical member 2 and the lattice member 3 in a state temporarily secured with the bolt 4, and by tightening the bolt 4, the joining can be easily performed.

As mentioned above, FIGS. 3 to 8 each show an example of the joining method, and the method is not limited to these.

FIG. 9 is a reference 1 for explaining an example of the arrangement of load-bearing panels l in the framework structure of the present invention! (In the case where there is no vertical frame member 12 and horizontal frame member 13 in the present invention), load-bearing panels can be installed between upper and lower horizontal members 5 such as beams, girders, and foundations, in addition to general columns. Vertical members 6 (of course, including those arranged as regular columns and studs) are provided that constitute the framework, and load-bearing panels 1 are distributed within the framework.Specifically, the columns, opening positions, and shafts are Taking into account the required strength of the assembly, the design determines the efficient arrangement of the horizontal load-bearing members.

〔Effect of the invention〕

The load-bearing panel of the present invention is made into a unit by attaching a lattice member in which rod-like members are arranged in a wave pattern on both sides of a vertical member such as wood, and then pasting a panel on one side, and it is lightweight and has a high horizontal load-bearing capacity. It can be used as a member.

The joining of the lattice member and the frame material can be installed at the factory, and the precision can be achieved, making it possible to create a light but strong joint. In addition, when attaching panel frame materials to the framework, if you provide a clearance in consideration of the on-site construction accuracy of the framework, errors can be absorbed, and force transmission can be achieved by using the packing materials in between and using the nails. You can either join them together, or you can attach a larger piece of face material and nail it to the frame at the protruding part (in this case, packing material is also not required).

Note that when the lattice member is axisymmetric with respect to the central vertical member, a large force is not generated in the central vertical member when a horizontal force is applied, so that the vertical member can be made to have a small cross section. Further, if the lattice member is arranged in a closed shape with respect to the horizontal member as in No. IM, there will be fewer attachment parts for the lattice member, and force transmission will be streamlined.

The framework structure of the present invention uses load-bearing panels that have the above-mentioned effects, which improves workability, and allows for wider openings compared to braces or general wall structures, making it easier to arrange them. It also has a large degree of freedom, allowing for free space design.
