Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building realizing an excellent earthquake-resistant structure.

[0002]

2. Description of the Related Art A framed wall construction method, commonly known as a two-by-four construction method, allows a wall to be constructed efficiently by arranging and fixing it on a platform, which is a panel floor with a frame, without using a pillar. In contrast, in the conventional framing method, a column is fixed vertically to a base, a beam is fixed to the upper end of the column, and then a wall is constructed at a portion surrounded by the base, the column, and the beam. In the conventional framing method, a wall can be constructed by fixing a framed panel between a base, a column, and a beam.

[0003] In a building of the frame construction method in which the base and the beam are connected by columns, the joint between the base, the column and the beam is reinforced to improve the earthquake resistance. The present inventor has shown in FIG.
As shown in (1), a building was developed in which the base 1A, the pillar 2 and the beam 1B were connected with the reinforcing metal fitting 3 (Japanese Patent Application No. Hei 7-29769).
2). In the building of this figure, as shown in FIG. 2, the pillar 2 is inserted into the cylindrical portion 3A of the reinforcing metal fitting 3, the base 1A and the beam are inserted into the groove 3B of the reinforcing metal fitting 3 and connected, and the structural material is extremely reduced. There is a feature that can be strongly connected. Furthermore, this connection structure does not require a timber processing called a “cut”, in which holes and protrusions for inserting columns are provided in the base and beams as in a conventional wooden building, so that the timber connection portion is not required. There is also a feature that can easily process.

[0004]

However, as shown in FIGS. 1 and 2, in a building in which a base, a column and a beam are connected by a reinforcing metal, a connecting portion between the base, the column and the beam is reinforced by a reinforcing metal. So it is not used for pillar-free two-by-four buildings. In the two-by-four building, the structural plywood is fixed to the framed panel, so that the framed panel itself can have a considerably tough structure. However, in a two-by-four building, it is extremely difficult to provide an excellent earthquake-resistant structure because the framed panel is fixed to a horizontal structural member such as a platform or a beam with a nail penetrating the horizontal mounting frame. This is because, in the event of an earthquake, when a force acts in the direction indicated by the arrow A in FIG. 3, the nail 10 for fixing the horizontal mounting frame 5A to the horizontal structural member 1 comes off.
Further, even more troublesome, when the nail 10 penetrating the horizontal mounting frame 5A comes off, even if a force acts in the direction shown by the arrow B, the nail 10 that has come out is inserted again into the original position. No, the seismic resistance of the walls is significantly reduced. For this reason, even if the framed panel 4 itself has excellent strength, it is difficult to nail and firmly fix it. For this reason,
The two-by-four building has an excellent seismic structure, but has the drawback of being extremely difficult.

The inventor of the present invention has aimed at solving this drawback by using a connecting metal plate 6 having a simple structure as shown in FIG. 4 without using a reinforcing metal fitting having a complicated shape. Developed a two-by-four building that improves the earthquake resistance of the walls.

In the two-by-four building shown in FIG. 1, a structural plywood 4A of a framed panel 4 is vertically projected from a mounting frame 5 to provide a projecting portion 4a. The protrusion 4a is fixed to the horizontal structural member 1 by nailing or bonding. Further, a connecting metal plate 6 is nailed to the surface of the structural body plywood 4A. The connecting metal plate 6 is located at the boundary of the framed panel 4 that is fixed adjacent to the framed panel 4 and the horizontal structural member 1.
It is fixed by nailing to the connection part with the.

[0007] The two-by-four building shown in this figure can improve the earthquake resistance as compared with the conventional building. However, since the building with this structure improves the earthquake resistance with the connecting metal plate,
When the connecting metal plate comes off the framed panel, the seismic strength decreases. A large number of nails are used to secure the connecting metal plate. However, even if a large number of nails are used, it is difficult to firmly fix the connecting metal plate. It's a nail,
This is because the connection metal plate and the framed panel are locally connected. The nail and the adhesive can be used together for fixing. However, as the adhesive degrades over time, the strength will decrease over decades. Furthermore, when an extremely strong force acts locally due to an earthquake or the like, there is a drawback that the nail is pulled out or the adhesive part is peeled off and the strength is reduced.

Furthermore, even if the connecting metal plate does not come off, the connecting metal plate locally reinforces the connecting portion of the framed panel, so it is difficult in principle to significantly improve the earthquake resistance of the whole building. .

The present invention has been developed for the purpose of further improving the seismic resistance. An important object of the present invention is to provide a two-by-four building which can have a simpler structure and can realize more excellent seismic resistance. Is to do.

The two-by-four building according to the first aspect of the present invention has a feature that it can realize excellent earthquake resistance with a simple structure. That is, the two-by-four building of the present invention connects a frame constructed by connecting a plurality of framed panels on a foundation, connecting the ends of a metal band bound to at least one of the foundation, the base and the platform, This is because the building is fixed so as to bind it. In this way, in a building in which both ends of the binding metal band are fixed to the foundation, base, platform, or the like, the entire building can be bound as if the luggage were bound. This structure is different from the conventional structure in which the connecting portions of the framed panels are locally connected, and the entire building can be connected and reinforced. For this reason, even if an extremely strong force acts locally due to an earthquake or the like, there is a feature that the entire building can be reinforced in an ideal state for a long time without reducing the strength of the building. Therefore, the two-by-four building of the present invention significantly improves the seismic resistance of the whole building,
Excellent earthquake resistance can be realized.

Further, the two-by-four building according to the second aspect of the present invention is characterized in that the binding metal band can be more firmly connected to the frame. This is because this building connects one end of the binding metal band to at least one of the foundation, the base, and the platform, and connects the other end of the binding metal band to the beam via the connection tool. Furthermore, the building which connects the binding metal band to the beam via the connecting tool is not connected in a state where the whole building is bound, and in other words,
The feature is that the binding metal band can be shortened and easily connected. The binding metal band having a short overall length has features that it can minimize the expansion and contraction due to heat and tension, can connect more firmly, and can reduce the cost.

Further, in the two-by-four building according to the third aspect of the present invention, one end of the binding metal band is connected with a connecting member.
Because it is connected to the foundation, or foundation, of the binding metal band
