Description

[Detailed description of the invention] [Technical field] This invention prevents condensation from condensing on the indoor side of the fixed plate made of steel plate etc. when attaching an external wall panel such as ALC to a fixed plate fixed to the top surface of the foundation. This invention relates to a mounting structure for exterior wall panels that prevents this from occurring.

[Background technology] Conventionally, when fixing an external wall panel such as an ALC to a foundation, as shown in Fig. 2, a horizontal piece 2 and a vertical piece 3 are attached to the top surface of a concrete foundation 1 to form an inverted T-shaped cross section. At the same time, the outdoor end of the horizontal piece 2 is made to protrude outdoors, while the lower end of the outer wall panel 6, called a lightning plate, is bent indoors. The bent mounting plate 7 is attached with bolts and nuts 14, 9, etc., and the vertical piece 3 of the fixing plate 4 is inserted between the mounting plate 7 and the back side of the outer wall panel 6, so that the outer wall panel 6 is fixed. Place the lower end on the horizontal piece 2 of the fixing plate 4, then tighten the nut 9 to sandwich the vertical piece 3 between the mounting plate 7 and the outer wall panel 6, and in this way the lower end of the outer wall panel 6 The part was fixed to the fixed plate 4 of the foundation 1. However, the fixing plate 4 is made of a steel plate or the like, and when the mounting portion 5 exposed outdoors is cooled, the fixing plate 4 becomes a cold-thermal bridge, causing dew condensation on the indoor side of the fixing plate 4. The interior floor, etc., was damaged. Note that 10 in the figure is a surface layer formed of mortar or the like.

[Purpose of the invention] The present invention has been made in view of the above points, and consists of exposing the outdoor end of the fixed plate to the outdoors and placing the outer wall panel on the top surface of this mounting part. It is an object of the present invention to provide a mounting structure for an external wall panel that does not cause dew condensation inside even when the panel is mounted.

[Disclosure of the invention] In other words, the mounting structure of the exterior wall panel of the invention is as follows:
Horizontal piece 2 and vertical piece 3 form an inverted T cross section on the top surface of foundation 1.
A fixed plate 4 formed in a letter shape is placed and fixed, the outdoor end of the horizontal piece 2 is extended from the outdoor surface of the foundation 1 to the outdoor side to form a mounting part 5, and the lower end of the outer wall panel 6 is A mounting plate 7 placed on the upper surface of the mounting portion 5 and fixed to the inside of the lower chamber of the outer wall panel 6 is attached to the vertical piece 3 of the fixing plate 4, and a heat insulating material 8 is arranged on the lower side of the horizontal piece 2. The heat insulating material 8 disposed on the lower surface of the horizontal piece 2 prevents the outdoor end of the horizontal piece 2 from being cooled and prevents dew condensation from forming on the indoor end of the horizontal piece 2. However, the above objectives have been achieved.

The present invention will be described in detail based on the illustrated embodiments. As shown in Fig. 1, the fixing plate 4 made of a steel plate or the like is formed of a horizontal piece 2 and a vertical piece 3, and is a long member with an inverted T-shaped cross section.This fixing plate 4 is made of concrete or the like. Anchor bolts 15 placed on the top surface of the foundation 1 and fixed to the top surface of the foundation 1
The horizontal piece 2 of the fixing plate 4 is fixed to. The outdoor end of the horizontal piece 2 of the fixing plate 4 extends from the outdoor surface of the foundation 1 to the outdoor side, forming a mounting portion 5. The outer wall panel 6 is made of ALC, concrete, etc., and a recess 11 for a joint is formed on the outdoor side of the lower end. A bolt 14 is embedded and fixed in the indoor side surface of the lower part of the outer wall panel 6. A through hole 12 drilled in the upper end of the mounting plate 7 is inserted into the bolt 14, and a nut 9 screwed into the bolt 14 is inserted into the bolt 14. The mounting plate 7 is fixed to the bolts 14.
The heat insulating material 8 is disposed on the lower face side of the horizontal piece 2 of the fixing plate 4 while being covered from the lower face side by the heat insulating cover 13, and is fixed by bending upward to the outdoor side of the heat insulating cover 13. Piece 13 is recess 1 of outer wall panel 6
A lower piece 17 formed by bending downward at the indoor end of the heat insulating cover 13 is fixed to the outdoor surface of the foundation 1 with a fixing tool 18, such as a nail. The heat insulating cover 13 is attached to the lower part of the outer wall panel 6. A water cutter 19 is suspended downward from the lower part of the outdoor side of the heat insulating cover 13. Further, a sealing material 20 is filled into the recess 11 from the upper surface of the heat insulating cover 13 .

Therefore, the heat insulating material 8 is disposed from the lower surface of the horizontal piece 2 of the fixed plate 4 to the lower surface of the outer wall panel 6, so that the outdoor end of the horizontal piece 2 is not exposed to the outside. Therefore, the horizontal piece 2 is not cooled by outdoor cold air, and no dew condensation occurs on the indoor end of the horizontal piece 2. Moreover, even when the outer wall panel 6 is made of ALC or the like, the cut end of the lower end surface does not get wet with water and has a draining function.

[Effects of the invention] As described above, in the present invention, a fixed plate is mounted and fixed on the upper surface of the foundation, and the outdoor end of the horizontal piece is extended from the outdoor surface of the foundation to the outdoor side to form a mounting part. The lower end of the exterior wall panel was placed on the top surface of the mounting part, and the mounting plate fixed to the inside of the lower room of the exterior wall panel was attached to the vertical piece of the fixed plate, so the exterior wall panel protruded from the foundation to the outdoors. It can be placed on the mounting part of the fixed plate and fixed firmly, and since the insulation material is placed on the bottom side of the horizontal piece, the insulation material placed on the bottom side of the horizontal piece can This prevents the outdoor end of the horizontal piece from being cooled, prevents the fixed plate from becoming a cold-heat bridge, and prevents internal floors from getting wet. .
