Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an extremely novel insertion corner that improves ventilation on the back side of the outer wall of a building.

Buildings, especially wooden buildings, can be made to last for a long time only by using high-quality wood and by providing good air circulation. However, in conventional methods of constructing the exterior walls of buildings, which are often found in ordinary homes, whether it is the wet mortar method or the siding method, the biggest problem is air permeability. , several improvements have already been proposed. However, conventional passive countermeasures such as creating ventilation holes in walls or under floors to remove internal moisture do not provide fundamental solutions such as improving ventilation to the inside of external walls. I didn't get it.

Therefore, in this researched and developed invention, aluminum,
It has the advantage of being able to be constructed using materials such as steel plates and plastic acid at an extremely low cost and using a simple construction method.It is mainly used in the corner areas of wooden buildings where the outer walls are coated with mortar. The outer part of the pillar used for this purpose is hollow inside, and the longitudinal side surfaces are formed into a wing-like shape.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

Regarding construction methods for wooden foundations, for example, there are methods such as "vertical siding with joints," but examples of mortar-coated wall construction used in general wooden buildings are shown in Figures 1 and 3. Normally, first, a base plate 2 was placed on the outside near the pillar 1, then asphalt felt 3 and metal lath 4 were installed, and then a mortar coating 5 was applied.

If the entire perimeter of the building's outer wall is constructed using this method,
Despite originally requiring sufficient air permeability, this causes great damage to mortar-coated walls and also considerably affects the lifespan of the mortar.

In order to solve these problems, in the present invention, as shown in the plan view of FIG.
Apply siding 7 etc. to the outside of this, and apply this first
In the figure, a hollow insertion corner 8 made of a material such as aluminum, steel plate, or plastic is provided at the outer corner of the column 1 in close contact with one side of the crossbar 6 and siding 7. . Furthermore, on one longitudinal side (arrow a) of the outer circumferential surface of this insertion protruding corner, as shown in FIG. 9 is installed, and since the wind enters according to the b arrow, it prevents direct sunlight and rain from blowing in, and also has the effect of improving ventilation.

In this way, the air from the blades 9 flows to the insertion corner 8, and the air coming out of the ventilation holes provided at arbitrary points in the insertion corner 8 is further directed to the back surface of the mortar-coated wall or the back surface of the siding. Since it flows between the interior materials and the exterior wall substrate, it can achieve sufficient ventilation and make the mortar-coated walls last longer. It has the advantage of being able to maintain its overall lifespan for a long time.
