Description

Description: TECHNICAL FIELD The present invention relates to an outer wall panel that can be suspended integrally with a beam to improve workability and reduce deformation due to a load from the beam.

[Background technology]

The building of the dry construction method that uses walls, floors, roofs, etc., to form panels is often used. In such a dry construction building, in addition to the panel joining method of sequentially assembling the panels using connecting fittings, the so-called ramen construction method, in which the panels are attached to the frame formed by columns, beams, etc. Has been adopted.

However, in such a conventional ramen construction method, as shown in FIG. 10, after forming a skeleton in which beams B and the like are bridged in advance between columns A ... Standing on a foundation, a panel P is attached to the skeleton. It is retrofitted. Therefore, the panel P has to be mounted after waiting for the formation of the skeleton, and the number of construction days is extended as a whole.

Further, in the conventional ramen construction method, as shown in FIG. 11, the upper end of the panel P is inserted into the crown portion provided on the lower surface of the beam B, or, as shown in FIG.
The hanging piece of the beam B is clamped and supported by using the fixing metal fitting D having D1. The lower end is attached by fitting the base metal fitting E, which is fixed in advance on the basis of the groove provided on the lower surface.

As described above, in the structure in which the beam B is installed in advance to form the skeleton, the panel P needs to be inserted obliquely at the time of mounting, and great care must be taken in assembling.
In particular, in the case where the upper end is inserted into the crown portion of the beam B shown in FIG. 11, the lower end must be dropped and inserted, which makes mounting more difficult. Since it is attached to one piece, it is necessary to increase the rigidity of the hanging piece, which tends to increase the member cost.

Therefore, as shown in FIG. 9, the outer wall panel P and the beam B are integrated in advance and are arranged between the pillars A by using a crane or the like, thereby significantly improving the construction work of the house. It was devised. However, with the conventional fixing metal fittings D and the like, the fixing of the outer wall panel P and the beam B is incomplete, so that it is difficult to suspend them integrally.

On the other hand, for this reason, when the beam B and the outer wall panel P are connected directly or by using a metal fitting whose height cannot be adjusted, the load applied to the beam B after the deformation or construction at the time of mounting the beam B is directly applied to the outer wall. It is transmitted to the panel P, and as a result, the outer wall panel P tends to be deformed, such as distorted or displaced.

[Object of the Invention]

It is an object of the present invention to provide an outer wall panel that can significantly improve assembly efficiency and reduce deformation by using a beam mounting bracket that can be suspended integrally with a beam and whose height can be adjusted.

And a strong house can be provided. Beam mounting bracket 11 is the main unit 10
Lower metal fitting 2 to be attached to the upper metal fitting 3 fixed to the lower surface of the beam B
Move relatively up and down through the slide groove 4,
It is possible to prevent an error in mounting the beam B, a load acting on the beam B after the mounting, or the like from being transmitted to the outer wall panel P, and prevent a displacement deformation or the like.

〔The invention's effect〕

As described above, the outer wall panel of the present invention can be fixed to the main body by the beam attachment fittings, and therefore the beam can be bolted in advance. As a result, the outer wall panel and the beam can be integrally mounted between columns. Moreover, by fixing the beams to the columns respectively, the outer wall panel can be attached at the same time as the frame structure of the house is formed, and the efficiency of on-site construction can be improved. In addition, such an outer wall panel can be easily lifted and mounted by a crane or the like, which enables mechanization in building a house and can improve safety and quality of work. In addition, the beam mounting bracket can be freely adjusted in its vertical position through the slide groove while the lower bracket that is mounted on the main body and the upper bracket that is mounted on the beam are prevented from coming off by the locking piece. Therefore, it is possible to prevent twisting due to mounting error of the beam, transmission of load acting on the beam after mounting the beam to the outer wall panel, distortion, movement of the outer wall panel,
In addition to preventing deformation and the like, the upper fitting includes a beam fixing piece fixed to the lower surface of the beam, so that the beam can be arranged directly above the outer wall panel.
