Abstract

PURPOSE:To enable mass production while improving quality by joining lattice members, to which cylindrical members are arranged to a corrugated shape, on both sides of a central longitudinal member. CONSTITUTION:Lattice members 3 in which steel pipes are bent to a corrugated shape, and abutting sections against a central longitudinal member 2 are formed flatly are joined on both sides of the longitudinal member 2 by bolts 4, etc., thus shaping a load bearing panel 1. The load bearing panel 1 is incorporated into a framework surrounded by upper and lower lateral members 5 such as beams, girders, sills, etc., and longitudinal members 6 such as poles.

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 load-bearing panel for construction of the present invention is a unit formed by joining lattice members in which steel pipes, reinforcing bars, and other rod-like members are arranged in a wavy manner on both sides of a central vertical member. 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 frame structure of the present invention, the above-mentioned roof panel-resistant unit is arranged within a framework formed by upper and lower horizontal members and left and right vertical members that constitute the building frame. 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〕

Figure 2 shows a load-bearing panel 1 as a unit, which consists of vertical members 2 (usually made of wood) and lattice members 3. 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. , constitutes a planar horizontal load-bearing member. Figure 2 shows the lattice member 3.
This is an example in which the direction of the lattice member 3 is reversed to that of the embodiment shown in FIG. In the example shown in FIG. 2, the upper and lower ends of the lattice member 3 are open.

Such a load-bearing panel 1 is in a unitized state, and the third
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. Typically, the vertical members 6 are columns or studs;
, the bent portion of the lattice member 3 that contacts the vertical member 6 is joined with a bolt 4 or the like. Further, 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.

4 and 5 show the vertical members 2 constituting the load-bearing panel 1.
This figure shows an example of a joint between a vertical member 2 and a lattice member 3, in which a fixing plate 8 made of steel plate with screw holes 7 provided on both sides of the vertical member 2 is fixed with wood screws 9, and a flat lattice member 3 is attached. A bolt 4 passing through the vertical member 1 is inserted into the abutting portion to join the members.

Figure 6 shows details of the joints between the vertical members 6 such as columns that make up the framework of the building and the lattice members 3 that make up the load-bearing panel 1. This can be done in the same way as the joining of the lattice members 3. In this case, only one side of the vertical member 6 is joined.

FIGS. 7 and 8 show vertical members 2 constituting the load-bearing panel 1.
The installation method to the upper and lower horizontal members 5 is an example of the method.
A bracket 11 protruding from the substrate 10 at right angles is attached to the vertical member 2.
At the same time, the board 11 is attached to the horizontal member 5 using wood screws or the like.

The above FIGS. 4 to 8 each show an example of the joining method, and the present invention is not limited to these.

Fig. 9 shows an example of the arrangement of load-bearing panels 1 in the framework structure of the present invention, in which the load-bearing panels are installed between upper and lower horizontal members 5 such as beams, girders, and foundations, in addition to ordinary columns. Vertical members 6 (of course including those arranged as ordinary columns and studs) constituting a framework are provided, and load-bearing panels 1 are distributed within the framework. Specifically, pillars, opening positions,
Taking into account the required strength of the framework, the design determines the efficient arrangement of the horizontal load-bearing members. Figure 10 shows the relationship with other structural members in a wooden building structure using the frame shown in Figure 9. In principle, it can be constructed using conventional construction methods, and by using additional fittings etc.
Mass production and rationalization of construction can be achieved. In addition, in the figure, 12 shows the RC foundation, 13 shows the main drawer, 14 shows the cantilevered veranda part, 15 shows the balcony handrail, 16 shows the rafters, 17 shows the field board, 18 shows the asphalt roofing, and 19 shows the roof finishing material.

〔Effect of the invention〕

The load-bearing panel of the present invention is made into a unit by attaching a lattice member in which bar-shaped members are arranged in a wave pattern on both sides of a vertical member such as wood, and can be made into a lightweight and strong horizontal load-bearing member.

In addition, if the lattice member is line symmetrical with respect to the central vertical member,
Since no large force is generated in the central vertical member when horizontal force is applied, the vertical member can have a small cross section. Further, if the lattice member is arranged in a closed shape with respect to the horizontal member as shown in FIG. 1, 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.
