Description

[Detailed explanation of the idea] This idea concerns the outer wall structure.

As shown in Fig. 1, the conventional exterior wall structure has a U-shaped bracket 3 cut from channel steel on the upper surface of a horizontal piece 2a of an upper frame 2 made of channel steel attached to the upper part of the first floor outer wall 1. Place and fix the piece 3a, attach the end face 4a of the second floor panel 4 to the vertical piece 3b of this U-shaped bracket 3, and attach the two
The horizontal piece 6a of the cross-sectional lower frame 6 attached to the lower part of the floor outer wall 5 is placed and fixed, and the upper end of the curtain plate 7 is fixed to the lower extending piece 6b of the lower frame 6 with screws 8. The curtain plate 7 is attached by fixing the lower end of the plate T to the vertical piece 2b of the upper frame 2 with screws 9, and the curtain plate 7 and the exterior material 10 of the second floor outer wall 5 and the exterior material 11 of the first floor outer wall 1 are connected. The joints formed between the two are filled with caulking material 12.

In this case, the connection and fixation between the treasure-shaped metal fittings 3 and the first floor outer wall 1 is as follows:
A bolt hole (not shown) is provided in the horizontal piece 2a of the upper frame 2 in advance, and a nut 1 is inserted corresponding to the bolt hole.
3 is welded to the lower surface of the horizontal piece 2a, and a bolt hole (not shown) is provided in the horizontal piece 3a of the U-shaped metal fitting 3 in correspondence with the bolt hole provided in the horizontal piece 2a of the upper frame 2, Insert the bolt 14 through the spring washer 15 into the bolt hole of the horizontal piece 3a of the U-shaped metal fitting 3 and the bolt hole of the horizontal piece 2a of the upper frame 2, and then tighten the nut 13.
This is done by screwing it on.

The connection and fixation of the U-shaped metal fitting 3 to the second floor panel 4i and the second floor outer wall 5 are also performed using nuts 13'.

13" and bolts 14', 14" in a similar manner.

16 is a flooring material attached to the second floor panel 4, and 17 is a baseboard.

However, in such a structure, the curtain plate 7 must be attached and the caulking material 12 must be filled in two places, which requires time and effort, and furthermore, the appearance is not good because the caulking material 12 is filled in two places. It had the disadvantage of impairing the

Therefore, the purpose of this invention is to provide an exterior wall structure that is easy to construct and has an improved aesthetic appearance.

An embodiment of this invention will be described with reference to FIG.

In this embodiment, instead of the conventional channel steel, the upper frame 19 of the first floor exterior wall panel 18 is made of H-beam steel, in which one bent part of the channel steel is extended in the vertical direction, and the exterior material 20 is also It extends upward compared to the conventional case and is attached to the outdoor surface of the long piece 19a of the H-shaped upper frame 19, leaving the outdoor surface upper part 19b.

That is, the upper end surface 20a of the exterior material 20 is positioned slightly below the upper end of the long piece 19a.

In addition, the inverted lower frame 22 and exterior material 23 of the second floor exterior wall panel 21 are also connected to the h-shaped upper frame 19 of the first floor exterior wall panel 18.
It is formed symmetrically with the exterior material 20.

That is, the length ff22a of the inverted lower frame 22 is located on the outdoor side, and the end surface 23a of the exterior material 230 is located slightly above the lower end of the long piece 22a.

In this case, the heights of the long pieces 19a of the H-shaped upper frame 19 and the long pieces 22a of the inverted lower frame 22 are as follows when the first floor exterior wall panel 18 and the second floor exterior wall panel 21 are attached to the U-shaped bracket 3.
Upper end surface 20a of exterior material 20 and lower end surface 23a of exterior material 23
The height shall be such that they are very close to each other and face each other.

A notch hole 25 is formed in the lower part of the interior material 24 of the second floor outer wall panel 21 of the casing.

The construction procedure is as follows:
The lower horizontal piece 3a of the U-shaped bracket 3 is mounted and fixed on the upper surface of the horizontal piece 19c of the upper frame 19, and the end surface 4a of the second floor panel 4 is attached to the vertical piece 3b of the U-shaped bracket 3. Upper horizontal piece 3
The horizontal piece 22b of the inverted lower frame 22 attached to the lower part of the second floor exterior wall panel 210 is placed and fixed on the upper surface of c, and the outdoor upper part 19b of the long piece 19a of the h-shaped upper frame 19 and the inverted lower frame 22 Adhesive tape 26 is pasted on the outdoor lower part 22c of the long piece 22a, and a joint is created between the upper end surface 20a of the exterior material 20 of the first floor exterior wall panel 18 and the lower end surface 23a of the exterior material 23 of the second floor exterior wall panel 21. Fill the space with caulking material 27.

In this case, the connection and fixation between the second floor exterior wall panel 21 and the U-shaped bracket 3 is different from the conventional method, and the welding position of the nut 13'' is not on the horizontal piece 22b of the inverted lower frame 22, but on the upper horizontal piece of the U-shaped bracket 3. 3c, and the notch hole 25 of the second floor outer wall panel 21
Tighten the bolt 14" and attach the spring washer 15.
through the bolt hole (not shown) in the horizontal piece 22b of the inverted lower frame 22 and the bolt hole (not shown) in the upper horizontal piece 3C of the U-shaped metal fitting 3, and screwed onto the nut 13''. Let's do it.

Note that the notch hole 25 of the second floor outer wall panel 21 is covered by the baseboard 1γ, so that the exterior appearance is not affected.

The fixing of the U-shaped metal fitting 3 to the first floor outer wall panel 18 and the second floor floor panel 4 is the same as in the past.

In this way, this embodiment does not require a curtain plate (7 in FIG. 1) unlike the conventional structure, and only requires caulking at one location, so construction is simple and the aesthetic appearance is improved.

In addition, the first floor exterior wall panel 18 and the second floor exterior wall panel 21 are connected via the U-shaped bracket 3, and this connection is achieved by connecting the bolts 14 between the lower horizontal piece 3a of the U-shaped bracket 3 and the side of the H-shaped upper frame 19. At the same time, the bolt 14'' is inserted between the horizontal piece 22b of the inverted lower frame 22 and the upper horizontal piece 3 of the U-shaped bracket 3.
Since the bolts 14 and 14' are hidden within the outer wall and do not appear outside at all, the upper end surface 20a of the outer covering material 20 and the lower end surface 23a of the outer covering material 23 are arranged close to each other, i.e. Since the width of the caulking material 2T can be made narrower to make the caulking material 2γ less noticeable, the external appearance of the building can be improved in this respect as well.

As described above, the exterior wall structure of this invention has the advantage of being easy to construct and improving aesthetics.
