Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to the structure of the outer wall of a prefabricated house.

[Background technology]

The outer wall of the prefabricated house is formed by assembling an outer wall panel 1 formed by applying an outer wall board 3 and an interior wall board 11 to the outdoor side and the indoor side of a panel frame 10, respectively. Then, a curtain board 2 is attached to the gap between the outer wall panel 1 on the lower floor such as the first floor and the outer wall panel 1 on the upper floor such as the second floor to decorate the space. In other words, as a conventional example, Utility Model Publication No. 57-12122
There is a Japanese Patent Publication No. 1, which provides an engaging bending piece 12 at the upper end of a curtain plate 2 formed of a decorative metal plate and a fixing piece 13 at the lower end of the curtain plate 2, as shown in FIG. , engagement protrusion 1 of external wall panel 1 on the floor
The curtain plate 2 is attached by fixing the fixing piece 13 to the outer wall panel 1 on the lower floor while the engaging bent piece 12 is engaged with the fixing piece 13. And curtain plate 2
A sealant 4 such as caulking is filled between the upper end and the lower end of the outer wall board 3 of the outer wall panel 1 on the upper floor, and between the lower end of the curtain board 2 and the upper end of the outer wall board 3 of the outer wall panel 1 on the lower floor. Curtain board 2 and exterior wall panel 1
It is designed to provide waterproofness between the However, in this case, waterproofing is only performed in one layer, and the waterproofness is particularly insufficient at the upper end of the curtain plate 2, and the outdoor surface of the curtain plate 2 and the outdoor surface of the outer wall panel 1 are not flush with each other. All in all, the changes were slow and there were problems with the appearance.

[Purpose of invention]

The present invention was developed in view of the above points, and is an exterior wall structure that can ensure waterproofness at the upper end of the curtain board and also allows for decoration between the curtain board and the exterior wall panel. The purpose is to provide the following.

[Disclosure of invention]

However, in the structure of the exterior wall according to the present invention, there is a curtain plate 2 between the exterior wall panel 1 on the upper floor and the exterior wall panel 1 on the lower floor.
is arranged to engage the upper end of the curtain plate 2 with the lower end of the exterior wall panel 1 on the floor, and also between the upper end of the curtain plate 2 and the lower end of the exterior wall panel 3 attached to the outdoor surface of the exterior wall panel 1 on the floor. is filled with a sealant 4, and a base plate 5 is attached so as to span the outer surface of the lower end of the outer wall board 3 and the outer surface of the upper end of the curtain board 2, and a border cover 6 is placed on the outer surface of the base plate 5, covering the base plate 5. It is characterized in that a sealing material 4 is filled between the upper edge of the border cover 6 and the outer surface of the outer wall board 3 of the outer wall panel 1 on the floor. The above object has been achieved by filling the space between the upper edge of the border cover 6 and the outer wall board 3 of the outer wall panel 1 with the sealing material 4.The present invention will be described in detail below with reference to examples. .

The outer wall panel 1 and the curtain plate 3 are formed in the same manner as shown in Fig. 1, and the curtain plate 2 is installed in the same manner, but as shown in Figs. 2 and 3, they are formed of wooden boards. The base plate 5 is arranged from the lower end outer surface of the outer wall board 3 of the upper floor outer wall panel 1 to the upper outer surface of the curtain board 2 so as to cover the sealant 4 such as caulking, and the outer wall board 3 and the panel frame The underlayment 5 is fixed to the exterior wall panel 1 on the upper floor by tapping screws 19 passing through the base 10. Reference numeral 16 in the figure is a border base, and a locking protrusion 18 is provided on a presser piece 17 that is folded back and bent downward from the upper end of the border base 16. This border base 16 is attached to the outer surface of the base base 5 with wood screws 28. At this time, the curved piece 20 at the lower end of the border base 16 is brought into elastic contact with the base base 5, and at the same time, the border base 16 is attached to the upper end surface of the base base 5. A watertight material 21 such as a neoprene sponge is attached to the locking protrusion 18 on the back side of the holding piece 17 whose lower end is brought into contact with the outer surface of the outer wall board 3 of the wall panel 1. This border base 16 is used by connecting a plurality of sheets by butting their ends together, and the butt-connected portions are filled with a sealing material 4 such as silicone sealant, as shown in FIG. 4a. On the other hand, the border cover 6 is formed by bending a decorative metal plate, and has a locking piece 23 extending downward from the tip of the upper end flange piece 22, and the upper end flange piece 23 extends downward from the locking piece 23 on the outdoor side. A presser protruding piece 24 is provided protruding from the lower surface of the border cover 22, and abutting pieces 25, 26 are provided protruding from the back surface of the middle section of the border cover 6. When attaching the border cover 6, the locking piece 23 at the upper end is locked to the back surface of the upper end of the holding piece 17 of the border base 16, and the front face of the upper end of the border base 16 is held down by the holding protrusion 24. Border base 1
6 with the border cover 6, and the contact pieces 25 and 26
are brought into contact with the border base 16 and the base base 5, respectively, and the lower end flange piece 27 of the border cover 6 is brought into contact with the outer surface of the curtain plate 2, and in this state, the wood screws 28 passed through the border cover 6 are inserted into the base base 5. The border cover 6 is fixed by screwing into the border cover 6. This border cover 6 is composed of a straight main body border cover 6a and an L-shaped corner cover 6a, but a gap of about 5 mm is formed between the end surfaces of the main body border cover 6a and the corner border cover 6b. The end members fitted into each end are brought into contact with each other. After installing the border cover 6 in this way, apply a silicone sealant or the like between the locking piece 23 at the upper end of the border cover 6 and the outer wall board 3 of the outer wall panel 1 on the floor as shown in FIG. 4b. It is finished by filling with a sealing material 4. In the figure, 29 is a pillar cover. In the above, border base 16 is base base 5
The border cover 6 is positioned because the lower end of the holding piece 17 is in contact with the border cover 6, and the border cover 6 is positioned because its upper end is in contact with the upper end of the border base 16. Since the border cover 6 is fixed directly to the base plate 5 by screwing the wood screws 28 into the base plate 5, the border cover 6 can be fixed firmly and stably. It will be done.

[Effect of idea]

As mentioned above, in the present invention, the border cover hides the boundary between the top end of the curtain board and the bottom end of the exterior wall panel on the floor, and the border cover protrudes from the surface of the curtain board and the outside wall panel. Since it will be installed, it is possible to make changes to the exterior wall, and since sealant is filled between the upper edge of the border cover and the outer surface of the exterior wall panel of the exterior wall panel on the floor, The sealing material filled between the upper end of the curtain board and the lower end of the outer wall board can provide double waterproofing, and can improve the prevention performance at the upper end of the curtain board.
