Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a first-floor exterior wall panel used for a two-story building.

[Background Art] Conventionally, this type of panel has a C type as shown in Fig. 1.
The C-shaped channel frame material 4' is placed opposite the upper and lower parts of the panel main body 1', and the exterior material 3' is attached to one piece 4b' of the left and right side pieces 4b', and the lower piece 2 of the C-shaped channel beam 2' is attached.
a' is connected and fixed to the upper piece 4c' of the upper frame member 4'. That is, the C-shaped channel beam 2' and the outer wall panel main body 1' are assembled on-site, which is not preferable from the viewpoint of on-site work efficiency. Additionally, a particular problem is that the C-shaped channel beam 2' protrudes from the upper end of the exterior wall panel main body 1', so when actually used for a two-story building, the beam 2' is exposed between the upper and lower exterior wall panels. do. Therefore, it is necessary to cover this beam 2' with a curtain board or the like that is different from the exterior material 3', and waterproofing is also required for the upper piece 2a' of the C-shaped channel beam 2' and the upper exterior wall panel body. A total of two locations are required: between the lower piece 2a' of the beam 2' and the lower outer wall panel body.

[Purpose of the invention] This invention was devised in view of the above points, and its purpose is to improve strength by integrating beams into the exterior wall panel, and to simplify construction on site. Moreover, since the beams are not exposed, you can choose whether to attach a curtain board or not.
To provide a first floor exterior wall panel for a two-story building, which can be waterproofed in one place and is used for a two-story building.

[Disclosure of the invention] The present invention has such a structure that a C-shaped channel beam 2 is attached to the upper part of the outer wall panel main body 1 integrally with the outer wall panel main body 1 so as not to protrude from the upper part. Thus, the above-mentioned purpose of the present invention has been achieved.

The present invention will be explained in detail below with reference to Examples. In the figure, 1 is the exterior wall panel body, 2 is a C-shaped channel beam, which includes upper and lower pieces 2a, 2a and a vertical piece 2b that connects them.
It further includes a lateral groove 2c. Then,
This C-shaped channel beam 2 is located at the upper part of the exterior wall panel body 1, and the vertical piece 2b of the C-shaped channel beam 2 runs along and is attached to the inside of the exterior material 3. That is, the upper piece 2a of the C-shaped channel beam 2 and the exterior material 3
The height is approximately the same as the upper end surface of the main body 1, and the C-shaped channel beam 2 does not protrude. 4 is a C-shaped channel frame material, which includes a lower piece 4a fixed to the foundation 5;
It is composed of left and right side pieces 4b, 4b and a groove 4c. Thus, one piece 4b of the left and right side pieces 4b, 4b is attached along the inside of the exterior material 3.
FIG. 3 shows a state in which the present invention is actually used as a first floor exterior wall panel for a two-story building, and the conventional example shown in FIG. 1 is used for the second floor exterior wall panel. Of course, the device according to the present invention may be used on the second floor. Further, in addition to the C-shaped channel beam 2, a similar material to the C-shaped channel frame 4 may be attached to the beam facing each other, or it may be a wooden crosspiece.

[Effect of the invention] As described above, the invention is based on C fixed to the foundation.
Since the C-shaped channel frame material is attached to the lower part of the exterior wall panel body, and the C-shaped channel beam is attached to the upper part so that it does not protrude beyond the upper part, there is no need to assemble the exterior wall panel and beam on site, improving work efficiency on site. will improve. Further, since the C-shaped channel beam itself, which has a much higher mechanical strength than the C-shaped channel frame material, can be used as the frame material of the external wall panel, the strength of the panel is increased. Furthermore, when connected to the second floor exterior wall panel as shown in FIG. 3, the C-shaped channel beam portion is not exposed between the upper and lower floor panels, and can be treated with caulking. Therefore, there is no need to cover with a curtain plate, and the type of curtain plate to be attached or removed can be arbitrarily selected and handled. Furthermore, since the C-shaped channel beam is not exposed, only one location (between the upper and lower exterior wall panels) is waterproofed.
