Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a horizontal load-bearing member for a building, which is mainly mounted in a wooden frame of a house and bears a horizontal force.

[Conventional technology and issues]

Conventionally, in wooden structures, horizontal forces such as earthquakes are often dealt with by struts and wall arrangements.

However, conventional wood-structured buildings are not only limited by the strength of the timber, but also by the struts and walls as horizontal load-bearing members, which limit the degree of freedom in the design of openings and spaces. However, it takes a lot of time, and it requires a craftsman with special skills, which makes mass production difficult.

The present invention provides a new horizontal bearing member that can be prefabricated, and by incorporating this into a structural frame, enables mass production, increases the degree of freedom in design, and improves the rationalization and quality of construction. It is intended.

[Means for solving the problem]

The horizontal load-bearing member for construction of the present invention is a horizontal load-bearing member arranged in a framework of a wooden frame structure formed by upper and lower horizontal members 5 and left and right vertical members 6, and is a central wooden vertical member. 2 and a pair of wooden vertical frame members 12 on both sides thereof are connected between upper and lower wooden horizontal frame members 13, and lattice members 3 are respectively joined between the central vertical member 2 and both vertical frame members 12, Each of the lattice members 3 is formed by bending a steel pipe in a wavy shape to flatten the abutting portion thereof, and the abutting portion of each of the lattice members 3 is commonly bolted to the central longitudinal member 2 via a steel plate fixing plate 8. It is characterized in that the abutting portions of the lattice members 3 are individually bolted to the vertical frame members 12 on both sides via steel plate fixing plates 8.

The horizontal load-bearing member of the present invention provides a large strength as a reinforcing material for a wooden building frame structure, and a plurality of such horizontal load-bearing members having a large wall ratio are dispersed and arranged in the frame, so that entrances, entrances, windows, and the like are opened. The part can be widened, and the degree of freedom of design increases.

〔Example〕

FIG. 1 shows a horizontal bearing member 1 as a unit, which comprises a wooden vertical member 2, a lattice member 3, and vertical and horizontal frame members 12 and 13 surrounding these members. The lattice member 3 is formed by bending a single steel pipe in a wavy shape and flattening the contact portion with the vertical member 2. The lattice member 3 is joined to both sides of the vertical member 2 arranged in the center by bolts 4, and the frame member 12, Together with 13, a planar horizontal bearing member is formed.

FIGS. 4 (a) and 4 (b) show details of a joint between the vertical frame member 12 of the horizontal bearing member 1 and the lattice member 3, and since only one side is joined, FIG. Instead of the bolt hole 7 of (b), a fixing plate 8 'made of a steel plate having a screw hole 7' is used, and a bolt 4 'is screwed into the screw hole 7'.

FIG. 5 to FIG. 8 show a vertical member 2 with respect to a horizontal bearing member 1.
And an example of a method of attaching the upper and lower horizontal frame members 13 to each other. The vertical member 2 and the lattice member 3 are assembled,
In a state in which the joints 12 and 13 are assembled, a metal joint 16 is fixed to the lower surface of the upper horizontal frame member 12 and the upper surface of the lower horizontal frame member 12, and the bolts 4 can be joined using the joint metal member 16. I have to. The metal joint 16 has a rising portion 17 which sandwiches the end of the vertical member 2 from both sides in the in-plane direction (when the metal fitting 16 is attached downward as in the case of the upper end of the vertical member 2, the rising portion 17
The rising portion 17 is formed with a guide groove 18 that opens in both outward directions of the horizontal load-bearing member 1.

The details of the joining portion are shown, and the joining hardware 16 is fixed with a wood screw 9 with its flat base contacting the horizontal frame member 12. Joining hardware on the upper and lower ends of the vertical member 2
The rising portion 17 of 16 abuts, and the lower end flat portion of the lattice member 3 abuts on the outside thereof, and is fixed by the bolt 4 penetrating therethrough. In the drawing, 4a is a nut.

By forming the guide groove 18 in the metal joint 16, when joining the vertical member 2 and the lattice member 3 to the frame members 12, 13, as shown in FIG. With the bolts 4 temporarily fixed, the rising portions 17 of the joining hardware 16 can be slid between the vertical member 2 and the lattice member 3, and the bolts 4 can be tightened as they are to easily join.

As described above, FIGS. 3 to 8 each show an example of the joining method, and the present invention is not limited thereto.

In the drawing, reference numeral 22 denotes an RC foundation, 23 denotes a pull-out, 24 denotes a cantilevered veranda, 25 denotes a veranda handrail, 26 denotes a rafter, 27 denotes a base plate, 28 denotes asphalt roofing, and 29 denotes a roof finishing material.

〔The invention's effect〕

The horizontal load-bearing member of the present invention comprises a central wooden vertical member, a pair of wooden vertical frame members on both sides thereof, upper and lower wooden horizontal frame members, and a joint between the central vertical member and both vertical frame members. And a lattice member formed as a unit, and can be a lightweight and strong horizontal strength member.

The lattice member bends the steel pipe in a wavy shape to flatten the abutment portion, and the abutment portion of the lattice member is joined to the central longitudinal member by a common bolt via a steel plate fixing plate. The abutment part of the lattice member on the frame material is bolted individually via a steel plate fixing plate, and the bent part receiving the pressing force due to the presence of the steel plate fixing plate is a wooden vertical member To prevent the strength from being reduced by cutting into
By converting from point support to multi-point support, rotation of the joining bolt due to shear force acting from the lattice member can be prevented,
A stable joining structure can be obtained.

The joint between the lattice member and the frame material can be factory-installed, and the accuracy can be improved, so that a light and strong joint can be achieved. In addition, when attaching the frame material to the frame, if a clearance is provided in consideration of the accuracy of the construction of the frame at the site construction accuracy, errors can be absorbed, and force transmission will be nailed with packing material sandwiched Alternatively, the face material may be larger and pasted and nailed to the frame at the protruding portion (in this case, the packing material is also unnecessary).

In the case where the lattice member is line-symmetric 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 have a small cross section. In addition, if the lattice member is arranged in a closed shape with respect to the horizontal frame member as shown in FIG. 1, the number of attachment portions of the lattice member is small, and the transmission of force is rational.

By using the horizontal load-bearing member of the present invention having the above-described effects in the frame structure, the workability can be improved, and the opening can be widened as compared with a bracing or a general wall structure. The degree of freedom in arrangement is great, and free space design is possible.
