Description

[Detailed explanation of the invention] (Industrial application field) This invention is attached to the outside corner of an air circulation type house, and is used only for air circulation type houses for the purpose of ventilation and insulation of the corner part. The present invention relates to a heat insulator for a protruding corner.

(Technical background) In recent years, along with the promotion of energy conservation, insulation has become common sense in houses.

Among these, the external insulation method is considered to have a high energy-saving effect.

However, if the outer wall, which is made up of surfaces such as a two-by-four, is covered with heat insulating boards, the wood is likely to corrode due to moisture and dew condensation.

In particular, there is no place for moisture to escape from the walls and the protruding corners of the corner pillars, and corrosion is even more pronounced, so a solution to this problem was desired.

(Problem that the invention aims to solve) This invention provides ventilation to the protruding corners of an air-circulating house, prevents moisture and moisture from accumulating, eliminates wood corrosion, and improves the durability of the house. It is something that we are trying to improve.

(Means for Solving the Problem) Therefore, in order to solve the above-mentioned problems, in this invention, the heat insulator for the protruding corner is manufactured from a foamed synthetic resin, and its shape is changed from the left side and the right side. It is formed into a rod shape with an L-shaped cross section, and has an engaging protrusion for connection at its upper end, an engagement recess for connection at its lower end,
A concave groove is formed on the lower outer side of each.

Furthermore, a vertical ventilation passage is formed at the inner corner portions of the left and right pieces, and the left and right inner sides of the ventilation passage are used as receiving portions.

(Function) As a result of the above-described configuration, if this projecting corner insulation body is fixed to the entire upper and lower length of the outer projecting corner of an air circulation type house, the ventilation passage will be connected to the entire upper and lower length, and air will flow into the ventilation passage. When it flows, it carries away moisture and moisture, thereby preventing dew condensation from forming inside the walls.

(Embodiment) Next, an embodiment of this invention will be described with reference to the drawings. FIGS. 1 and 2 show a heat insulator 1 for a protruding corner made of foamed synthetic resin. By joining the left side piece 2 and the right side piece 3 over the entire length of one end surface, it is formed into a rod shape with an L-shaped cross section,
An engaging protrusion 4 for connection at the upper end, an engagement recess 5 for connection at the lower end, and grooves 6, 6 into which the outer and lower edges fit.
are formed respectively.

Further, a vertical ventilation passage 7 is formed at the inner corner of the left side piece 2 and the right side piece 3, and the left and right inner sides of the ventilation passage 7 are used as receiving portions 8.

In the figure, reference numeral 11 indicates a heat insulating board attached to a column body 10 such as a corner post or stud, 12 indicates a base material such as lath attached to the surface of the heat insulating board 11, and 13 indicates a base material attached to the surface of the base plate 12. 14 indicates the foundation of the finished wall.

This invention is as described above, and its usage will be explained based on FIG. The engagement protrusion 4 of the corner heat insulator 1 is fitted into the engagement recess 5 of another protruding corner heat insulator 1. This procedure is repeated, the pieces are stacked one after another in a connected state, and temporarily fixed to the column 10 with nails.

Further, a heat insulating plate 11 is installed adjacent to the heat insulating body 1 for the protruding corner.
... are each temporarily fixed with nails to the column bodies 10 such as corner posts and studs.

After this temporary fixing, the concave grooves 6, 6 of the heat insulator 1 for the protruding corner
Then, the horizontal furring edges 9 are sequentially fitted into the grooves of the heat insulating plate 11 (the heat insulating plate 11 is provided with grooves corresponding to the grooves 6, 6 of the heat insulating body 1 for the protruding corners), and this body It is nailed to the pillar body 10 from above the edge 9, and then the heat insulating board 1 is
1... and base material 1 such as lath on the surface of the heat insulator 1 for the protruding corners
A finishing wall body 13 made of external wall boards or mortar is constructed through the walls 2 and 2.

(Effects of the invention) As described above, according to the heat insulator 1 for the protruding corner of this invention, the ventilation passage 7 is formed along the entire length of the corner of the column 10, and the ventilation passage 7 is used to protect against indoor temperature differences and sunlight. Air circulates appropriately depending on the strength of the beam, and this air circulation keeps the exposed corners of pillars such as corner posts and studs dry at all times, preventing moisture and condensation from forming in the corners. Corrosion of column bodies 10 such as columns and studs can be eliminated, and a building with excellent durability can be obtained.

In addition, by making the projecting corner heat insulator 1 L-shaped in cross section between the left side 2 and right side 3, it is easy to attach it to the column 10, and the thickness of the heat insulating board 11 attached to the wall can be reduced. If it is made uniform, the finished corner portion will be flush, which has the effect of making it easier to construct the finished wall body 13.

Furthermore, the engaging protrusions 4 and engaging recesses 5 provided at the upper and lower ends of the protruding corner heat insulator 1 allow for easy and reliable connection, a good fit, and the outer lower part of the left and right sides 2 and 3. The recessed grooves 6, 6 provided in the grooves 6, 6 have the effect of making it easy to attach using the furring 9.

The ventilation passages 7 provided on the inner surfaces of the left and right pieces 2 and 3 facilitate the flow of air in the vertical direction, and the support portions 8 and 8 formed on the left and right sides of the ventilation passages 7 reduce the thickness of the protruding corner insulation 1. In addition to reinforcing the material, it has the effect of conveniently fixing it to the column 10.

In addition, since the heat insulator 1 for the protruding corner is molded using foamed synthetic resin, it is not only easy to manufacture, but also lightweight and easy to transport.It also has excellent heat retention and heat insulation properties, and is easy to cut, making it convenient for construction. effective.
