Description

[Detailed description of the invention] (Field of industrial application) This invention fixes a heat insulating board having ventilation grooves between the inner and outer walls of a building, and connects the attic space and the underfloor space through the ventilation grooves of the insulation material. In the winter, the heat stored in the attic space is kept inside the walls through the ventilation grooves of the insulation board, and warm air is guided to the underfloor space to keep the underfloor warm, while in the summer, the cold air in the underfloor space is kept warm. This relates to a finishing material for the lower end of an exterior wall used in so-called air-circulating houses, which cools the inside of the wall through ventilation grooves while rising into the attic space and releasing only the hot air.

(Prior art) In recent years, as an energy-saving house, an air circulation type house has been developed in order to save on heating and cooling costs.The air circulation type house consists of a heat insulating board with ventilation grooves formed on the outer periphery of the inner wall. A waterproof sheet is attached to the surface of the insulation board, and a siding board is attached as an outer wall, and the ventilation groove must communicate with the ventilation gap formed by inserting a spacer between the fabric foundation and the foundation. Must be. By the way, when a siding board is used as an external wall, rainwater runs down the outer surface of the siding board and reaches the lower end.
A situation occurs where rainwater gets caught and infiltrates the back side. The outer surface of the siding board has a surface finish that prevents rainwater from entering, but there is no such surface finish on the bottom edge and back surface, which allows rainwater to enter the interior from the bottom edge and back surface, causing rot and mold growth. This causes a reduction in the lifespan of the siding board.

(Problem to be solved by the present invention) In this way, in an air circulation type house, the ventilation grooves in the heat insulating board fixed between the inner and outer walls and the ventilation between the fabric foundation and the foundation are formed by sandwiching spacers between the two. This requires communication between gaps and requires an outer wall to be provided on the outer surface of the heat insulating board, which poses problems such as the workability of the outer wall, water intrusion from the lower end of the outer wall, and insulation properties. The present invention was developed with the aim of solving the above-mentioned problems, and provides a finishing material for the lower end of an exterior wall that has good workability, prevents water from entering from the lower end, and takes heat insulation into consideration.

(Means for Solving the Problems) Therefore, the outer wall lower end finishing material according to the present invention has a cross section in which two horizontal sides that are parallel to each other are protruded from the vertical sides, and from the lower end of the vertical sides. It has a shape with a draining side that slopes diagonally downward, and is attached to the horizontal crosspiece of a heat insulating board fixed to the outside of the foundation via the vertical side, and the heat insulating board is inserted between the horizontal sides of the two pieces. There is no gap between the cloth foundations, and rainwater that travels along the outer wall of the siding boards is allowed to fall through the draining edges.

Hereinafter, one embodiment of the outer wall lower end finishing material of the present invention will be described in detail based on the drawings.

(Example) Fig. 1 shows a specific form of the finishing material according to the present invention, and the material is not particularly limited, but is generally made of a light alloy such as aluminum, stainless steel, or hard synthetic resin. It is a long material, and its cross section is composed of a first horizontal side 1, a second horizontal side 2, a vertical side 3, and a draining side 4 having an L-shaped tip. The first horizontal side 1 and the second horizontal side 2 form mutually parallel planes spaced apart from each other, and these form a right angle to the vertical side 3, and the second horizontal side 2
is formed at the lower end of the vertical side 3, and the tip 5 of the vertical side 3 is formed in the inward direction (the extending direction of the first horizontal side 1) so as to be in close contact with the heat insulating plate 13 when the tip 5 of the vertical side 3 is fixed to the horizontal crosspiece 12. direction). Furthermore, the draining side 4 is not perpendicular to the vertical side 3 but hangs downward, and the tip 6 is bent into an L-shape. Of course, it can be used and function as a finishing material for the lower end of siding even without the L-shaped tip 6, but the draining edge 4 is located at the lower end of the siding board and is always exposed to the outside. By forming the L-shaped tip 6, the bending strength and torsional strength are increased, and moreover, it can function as a seam. Therefore, the shape shown in FIG. 2 may be used.

FIG. 3 shows a usage condition in which the finishing material is attached to the lower end of the siding board 7.
4 is an enlarged view of part A of the air circulation type house shown in FIG. Flat spacer 1 made of resin
0 form ventilation gaps 11 at a constant pitch to allow air circulation between the underfloor and the inner and outer walls. By the way, the above finishing material has its first horizontal side 1
is fixed so that it almost coincides with the top surface of the cloth foundation 8, and is fixed with nails, screws, etc. to the horizontal crosspiece 12 attached to the outer periphery of the foundation 9, and the horizontal crosspiece 12
is fixed to the base 9 via a heat insulating plate 13.
The heat insulating board 13 is made of polystyrene foam or the like, and has a ventilation groove 14 formed in its cross section. It's communicating. By the way, as mentioned above, the finishing material is fixed to the horizontal bar 12 through the corner where the first horizontal side 1 and the vertical side 3 intersect. Since the ends of the first and second horizontal sides 2 do not reach the outer surface of the cloth foundation 8, a heat insulating plate 15 made of foamed polystyrene or the like is inserted between the first horizontal side 1 and the second horizontal side 2. Therefore, since the cushioning heat insulating board 15 is in contact with the uneven outer surface of the cloth foundation 8, there is no gap between the insulation board 15 and the outer surface of the cloth foundation 8, and moreover, the insulation board 15 is in contact with the foundation 9 and the horizontal beam 12. Can be fixed in parallel. A waterproof sheet 16 is attached to the outer surface of the heat insulating board 13, and siding boards 7 are attached and arranged to form a predetermined outer wall.

As described above, the outer wall lower end finishing material according to the present invention has a first horizontal side 1 and a second horizontal side 2 that sandwich the heat insulating plate 15 that is in contact with the outer surface of the cloth foundation 8, and the first horizontal side It is a long material of a certain length that is fixed to the horizontal crosspiece 12 through the corner of the second horizontal side 2 and the vertical side 3, and has a draining side 4 formed from the base of the second horizontal side 2, and has the following effects. be able to.

(Effects) (1) By fixing the finishing material to the lower end of the siding board 7, rainwater will fall down along the draining side 4 of the finishing material, thereby preventing water from entering the interior from the lower end of the siding board. This can prevent corrosion and mold growth of the siding board 7 and greatly improve its lifespan.

(2) Although the outer surface of the cloth foundation 8 is a somewhat uneven surface, when the first and second horizontal sides 1 and 2 of the finishing material are brought into direct contact with the uneven surface, the finishing material is applied to the cloth foundation 8. Furthermore, not only can it not be installed parallel to the foundation 9, but it also creates a gap, making it unsuitable for use as an air circulation type external wall. Moreover, they can be installed parallel to each other.
