DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a wall panel of a building.

[0002]

2. Description of the Related Art A conventional lower support structure of a wall panel is shown in FIG.
As shown in the figure, the wall panel supporting hardware 53 divided into a plurality of parts corresponding to the positions avoiding the columns 52 erected on the beams 51, the bolt mounting nuts 53a of the respective wall panel supporting hardware 53 with bolts and nuts.
The lower surface and the bottom surface of the wall panel 54 are supported by the upright portion 53b and the flat surface portion 53c of the wall panel support metal 53 by being individually mounted on the beams 51 by the 55.

[0003]

However, according to the above-mentioned prior art, when the number of pillars 52 erected on the beam 51 increases, the wall panel supporting hardware 53 increases in number corresponding to the number of pillars 52. If the part is divided and the number of parts increases, furthermore, if there is a place where the pillar 52 is not erected, the number of parts will increase due to the use of multiple types of wall panel support hardware 53 with different dimensions etc. At the site, the number of steps for classifying and distributing a large number of the divided wall panel support members 53 to predetermined positions of the beams 51 and the number of steps for individually attaching the large number of wall panel support members 53 to the beams 51 increase.

When the wall panels 54 are attached to the wall panel support hardware 53, a large number of individually independent wall panels 54 are attached to the wall panel support hardware 53 so that there is no step between the wall panels. Man-hours for finely adjusting the position and direction of the wall panel support hardware 53 are needed.Especially, the man-hours related to this adjustment are closely related to the accuracy of the wall finishing surface. Occupy it.

[0005] In addition, the number of parts of different types of wall panel support hardware 53 is increased in accordance with the difference in the standing positions of the pillars 52, so that the man-hours for managing the number of parts and the like are also increased, and the various man-hours mentioned above are reduced. When it increases, there is a problem that the workability of the wall panel is reduced and the construction period is long.

[0006] The present invention is to solve the above-mentioned problems,
It is an object of the present invention to provide a lower support structure for a wall panel and a method for constructing the same, which can reduce the number of on-site man-hours, shorten the construction period, and stabilize the quality accuracy of a finished wall surface.

[0007]

According to the present invention, there is provided a lower support structure for a wall panel, wherein a plurality of columns are erected on an upper surface of a beam at an interval of an integral multiple of a minimum module.
In the column and the lower support structure of a wall panel in which wall panels are juxtaposed in parallel, a beam mounting portion having a notch for avoiding the column at the minimum module interval, and a continuous wall receiving a back surface and a bottom surface of the wall panel A wall panel support having a panel receiving portion is fixed to a beam upper surface between the columns at the beam mounting portion,
The lower part of the wall panel is supported by the wall panel receiving portion.

In the method of constructing a lower support structure for a wall panel according to the present invention, a plurality of columns are erected on an upper surface of a beam at intervals of an integral multiple of a minimum module, and the column and the wall panels are arranged in parallel. A method of constructing a lower support structure for a wall panel, comprising: a beam mounting portion having a notch for avoiding a column at the minimum module interval; and a continuous wall panel receiving portion receiving a back surface and a bottom surface of the wall panel. The panel supporting hardware is fixed to the upper surface of the beam between the columns at the beam mounting portion, and then the lower portion of the wall panel is supported by the wall panel receiving portion.

According to the present invention, as described above, the long wall panel supporting hardware is disposed integrally on the beam, avoiding the pillars, and the wall panel supporting metal wall panel receiving portion of the wall panel supporting metal supports the long wall panel supporting hardware. The lower part is supported.

Accordingly, the plurality of wall panels are supported by the single wall panel support, so that the wall finishing surfaces of the plurality of wall panels are regulated by the wall panel receiving portions of the wall panel support and are easily aligned. Unlike the conventional example described above, it is not necessary to individually adjust the positions and directions of a large number of wall panel support hardware, so that the number of adjustment steps is reduced, and the quality accuracy of the wall finished surface can be stabilized.

In addition, since the number of wall panel support hardware to be used is reduced and the same wall panel support hardware can be used in common regardless of the installation position of the pillar, the various man-hours in the above-described conventional example can be reduced. The construction period of the wall panel can be shortened.

The flat plate B constitutes an upright portion 21c for receiving the lower rear surface of the wall panel 2, and the flat plate A and the flat plate B are integrally formed by welding. One wall panel support fitting 21 is formed with two minimum modules.

As shown in FIG. 5, similarly to the first embodiment, the wall panel supporting hardware 21 is provided between the hole formed at a predetermined position of the beam mounting portion 21b and the beam 1 between the columns 3. It is fastened by bolts and nuts 5 inserted through holes formed at predetermined positions on the upper surface of the flange 1a and is fixed on the upper flange 1a of the beam 1, and is provided by the upright portion 21c constituting a wall panel receiving portion. The lower back surface of the wall panel 2 is supported, and a flat portion
The bottom surface of the wall panel 2 is supported by 21d.

In the same manner as in the first embodiment, in the thickness direction of the lower part of the wall panel 2, an inner plate is fastened by bolts and insert nuts via an upright portion 21c constituting a wall panel receiving portion. Thus, the lower portion of the wall panel 2 is fixed and supported by the upright portion 21c and the flat portion 21d of the wall panel receiving portion. Other configurations are substantially the same as those of the first embodiment, and similar effects can be obtained.

[0033]

Since the present invention has the above-described configuration and operation, the long wall panel support metal is continuously and integrally connected to the wall panel by the notch, avoiding the pillar. Since the wall panel receiving portion that receives the back and bottom of the wall panel is configured continuously, there is no step between the multiple wall panels attached to one wall panel support, and the quality accuracy of the wall finished surface is stabilized. I can do it.

Further, as compared with the above-mentioned conventional example, the number and the number of parts of the wall panel supporting hardware are small, so that the position and the direction of the wall panel supporting hardware so that no step is formed between the wall panels attached to each wall panel supporting hardware. The number of man-hours to adjust is reduced, and the quality accuracy of the wall finishing surface can be stabilized,
Since the wall panel support hardware can be used in common regardless of the installation position of the pillar, the number of man-hours at various sites as in the conventional example described above can be reduced and the construction period can be shortened.
