Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall structure capable of smoothly transmitting an axial force and enhancing an outer wall strength.

[0002]

2. Description of the Related Art Buildings of a dry construction method in which walls, floors, roofs, etc. are formed by using panel bodies are often used. Further, in such a building, the dimensions of each part are determined with a module pitch, which is usually set between 80 and 100 cm, as a reference pitch.

However, conventionally, such a panel body, for example, an outer wall panel forming an outer wall of a house, has a relatively small width, for example, one reference pitch width or two reference pitch width is often used.

On the other hand, in order to form an outer wall of a house by using such a narrow outer wall panel, conventionally, the outer wall panel has been built directly by a joint fitting.

In the case of using such a joint metal fitting, conventionally, as shown in FIG. 20 as an example of the joint metal fitting SA for connecting the upper and lower outer wall panels PA and PB, a U-shaped base body S is shown.
The wing pieces SC and SD supporting the outer wall panels PA and PB were laterally arranged on the upper and lower sides of the B side. As a result, the base body SB is open between the winglets SC and SD, and the upper and lower outer wall panels PA and PB are not connected between them.

On the other hand, in order to improve the construction efficiency and the quality with the maintenance of production facilities, roads for transportation, etc.
Large-sized outer wall panels whose width is more than three times the standard pitch are being used.

[0007]

However, although the above-described joining metal fitting SA can be used for the outer wall panels PA and PB having a small width, in the case of a large and large outer wall panel, the joining metal fitting SA is used. Such a large panel cannot be sometimes used because the acting force becomes excessive and a large bending stress acts on the outer wall panels PA and PB due to an axial force from the roof or the like.

In the case of using a larger outer wall panel, when the height between the outer wall panels is increased so that the dimension between the ceiling and the floor panel above it is large for noise prevention and ventilation above the ceiling. However, at times like this,
The above-mentioned problem is increased, and it is difficult to use the conventional one.

The present invention is based on the fact that the upper and lower floors of the outer wall panel are connected to each other by using a beam member, and the axial force acting on the outer wall panel can be smoothly transmitted downward and the strength of the outer wall can be enhanced. The purpose is to provide a wall structure.

Bolt to. Therefore, the axial force from the roof or the like acting on the outer wall panel on the upper floor can be borne by the beam material to the foundation from the outer wall panel on the lower floor, and the force can be smoothly transmitted to improve the outer wall strength of the house. ..

Further, since the outer wall panels on the upper and lower floors and the beam members which are adjacent to each other with a gap therebetween are joined by using the fittings arranged on the upper and lower ends thereof, a large outer wall can be efficiently formed, and Since both ends of the upper and lower floors of the outer wall panel and the beam member are aligned, the beam member can efficiently disperse and support the load and enhance the rigidity of the house.

Further, by increasing the height of the beam member, for example, the distance between the floor panel forming the upper floor and the ceiling below the floor can be increased, thereby improving the vibration damping property and the ventilation property. Is also useful.

A curtain plate 91 with a gap G2 interposed therebetween is attached. The gap G2 is the gap G1 of the outer wall panel P.
By communicating with, it is possible to form an air flow path from the downstairs to the ceiling. In addition, since the heat insulating material 94 having air permeability is provided on the inner surface of the lattice beam R, ventilation of the attic is performed and dew condensation is prevented by the air flow. A ceiling plate SP is provided on the upper end of the outer wall panel P below the floor, and the floor panel FP supported by the floor support 69 is provided above the lattice beam R.

Further, as shown in FIG. 17, at the connecting portion of the joining metal fitting S1, the gap between the outer wall panels P, P is filled with the heat insulating material 95, while the outer surface thereof is covered with a suitable base material. A cover plate 96 that is flush with the face material 42 of the outer wall panel P is attached. A similar cover plate 97 is also provided on the inner surface.

Further, also in the portion of the joining metal fitting S2, the space between the side surfaces of the outer wall panels P, P is filled with the heat insulating material 95, and a cover flush with the face material 42 outside the outer wall panel is provided through the base material. The plate 96 is arranged at a right angle, and the corner portion C of the outer wall
1 and C2 are formed.

When the lattice beam R is used as the beam H in this way, the height of the beam can be freely determined, so that the degree of freedom of the height of the second floor and the ceiling is increased and the space between the second floor and the ceiling is increased. When the distance is set to a large value, it is possible to enhance vibration isolation, soundproofing, and ventilation of the ceiling.

Further, the weight is reduced and the cost of the house is reduced as compared with the case where a conventional shaped steel material having the same cross section and continuous shape is used.

Further, as in the above-mentioned embodiment, the braces can be bridged by using the mounting pieces 65 for mounting the braces shown in FIG. 11 to further contribute to the load of horizontal force.

Moreover, each member 12, 13, 1 of the lattice beam R is
4, 15, 16 are members 2, 3, 4, 5, of the outer wall panel P.
Shaped steel material with the same cross section as 6, 7, 9 is used, therefore
Since the outer wall panel P and the lattice beam R can form a continuous wall body having the same thickness and can reduce unevenness, the mounting height of the ceiling or the like can be freely set.

Further, since the vertical material 15 includes the two vertical pieces 51, 51 for separating the bolt insertion gap, the outer wall panel P is used.
It becomes easy to connect with etc.

[0072]

As described above, in the wall structure of the present invention, the beam member is bolted to the upper frame member of the outer wall panel below, and the lower frame member of the outer wall panel above the floor is bolted to this beam member. Therefore, the axial force acting on the outer wall panel from the roof, etc. can be smoothly transmitted to the beam through the outer wall panel, and can also be transmitted to the foundation from the downstairs outer wall panel, generating unnecessary stress. Can form a house outdoor wall with excellent strength.
