Description

[Detailed Description of the Invention] This invention relates to an air circulation type residential wall insulation board (hereinafter referred to as insulation board) that is used by being interposed between the interior and exterior walls of a building.

In recent years, construction methods in which various types of heat insulating materials are interposed between the inner and outer walls have become mainstream in the name of energy saving in houses.

However, simply interposing insulation materials not only promotes the formation of dew condensation and increases the corrosion of wall boards and pillars, reducing the durability of the building, but also blocks solar heat in the winter even when the sun is shining outside. Therefore, there were drawbacks such as the inability to effectively incorporate solar heat into the building.

This idea not only prevents dew condensation by using a specially structured heat insulating board made of foamed synthetic resin, but also absorbs solar heat through air circulation during the winter when the sun's rays are outside. It is installed inside a building to help heat the room and to average the room temperature in each room, and conversely, when there is no sunlight, it effectively maintains the room temperature as an insulator.
During the summer, hot air inside the building is exhausted to the outside, and cool air is circulated under the floor instead, making the room temperature more comfortable.

In addition, an appropriate number of vertical bars are arranged in parallel on the surface of the heat insulating board, a bottom plate is provided at the bottom end of the vertical bars, and an air inflow recess is formed between the vertical bars and the bottom plate, so that the outer wall receives sunlight and is heated. When this occurs, air convection occurs between the air inflow recess and both the inner and outer walls, and the air circulates around the outer periphery of the building, making the building cool in the summer and warm in the winter.

Furthermore, the insulation plates are formed with an upwardly inclined side and a downwardly inclined side, so that each insulation plate can be sequentially connected with a vent formed above, and a concave groove is formed at the lower end of the insulation plate into which the furring fits. This makes it easier to fix the heat insulating board.

Next, an embodiment of this invention will be described with reference to the drawings. A heat insulating board 1 made of foamed synthetic resin and having a substantially rectangular shape has an appropriate number of vertical bars 2 arranged in parallel on its surface higher than the lower end of the upper inclined side. , a bottom plate 3 is formed below the vertical bar 2, an air inflow recess 4 is formed between the vertical bar 2 and the bottom plate 3, and an upwardly sloping side 6 and a downwardly sloping side are formed at both the upper and lower ends parallel to the surface side. forming side 7;
Further, a ventilation hole 8 is formed at the end of the upper inclined side 6, an appropriate number of ventilation recesses 11 are formed at the lower inclined side 7 of the back surface, and a concave groove 5 into which the body rim fits is formed in the lower and lateral direction of the front surface. are doing.

In the figure, 11 is a ventilation recess that forms a gap between the lower back of the heat insulating board 1 and the base 19, 13 is an inner wall plate, and 14
is a cavity for air circulation, 15 is a column, 16 is a column 15,1
5... Studs erected between them, 17 are nails that fix the frame 12, 18 are various external wall boards that are stretched on the surface side of the insulation board 1..., 19 is the foundation, and 20 is the foundation, respectively. .

This device has the above-mentioned configuration, and the construction method is as follows: A large number of heat insulating plates 1 with air inflow recesses 4 facing outdoors and vents 8 facing upward are placed on a wall that receives sunlight. The entire structure is brought into close contact with a wall surface that does not receive solar radiation, and the pillars 15 and studs 16 are stacked and stretched sequentially upward from below the surface. At that time, each of the furring edges 12 is fitted into the concave grooves 5 of the heat insulating plates 1, and the furring edges 1
2 to the pillar 15 or stud 16 with nails 17.
Thereafter, an outer wall plate 18 is attached to the surface of the heat insulating plates 1, and an inner wall plate 13 is attached to the opposite side.

In addition, in addition to providing an underfloor ventilation hole in the foundation 20,
A foundation support is interposed between the foundation 20 and the foundation 19 to provide an underfloor space, a gap between the foundation 20 and the foundation 19, a ventilation recess 11 between the foundation 19 and the insulation board 1, and the insulation board 1.
The air inlet recess 4 and the vent 8, the air circulation cavity, the attic space, and the attic ventilation opening are communicated with each other, so that air can circulate or freely enter and exit each part.

Next, the action and effect will be explained.

First, in the winter, sunlight hits the exterior wall board 18, and the exterior wall board 18 that absorbs the solar heat gradually accumulates heat, warming the air between the air inflow recesses 4 of the heat insulating boards 1 and the back surface of the exterior wall board 18. The warmed air becomes lighter and rises from the vent 8 through the air circulation cavity 14 into the attic, and the air from under the floor is sucked in instead, creating a flow of air, and this cycle repeats. Therefore, solar heat is gradually introduced into the room through the inner wall plate 13.

Furthermore, as the outside air gets colder, the air between the air inflow recesses 4 and the outer wall board 18 gradually cools down and becomes heavier, and remains stationary between the air inflow recesses 4 and the outer wall board 18 to act as a heat insulator. .

Furthermore, in the summer, both the underfloor ventilation hole and the attic ventilation hole are opened, and the air heated by the sun's rays between the air inflow recess 4 and the back surface of the outer wall board 18 becomes hot air and flows outside through the attic ventilation hole. It releases cold air from under the floor and introduces it to create a cool atmosphere.

As described above, the heat insulating board of this invention significantly improves the heat insulating performance and ventilation performance, has the effect of preventing the occurrence of dew condensation, and has the effect of absorbing solar heat due to solar radiation and temperature changes in the outside world. At times, solar heat is absorbed through air circulation, and when insulation is required, it has an unprecedented effect of preventing heat from escaping from the building. In addition, the opposing upper and lower sloped sides provided at the upper and lower ends of the heat insulating board facilitate vertical stacking and connection, and a ventilation hole can also be reliably formed. Furthermore, the air inflow recess can be easily formed by the vertical crosspiece provided on one side of the heat insulating board and the bottom plate.
In addition, the vertical bars have the effect of making the heat insulating board tougher. Furthermore, by forming grooves into which the edges of the insulation board fit, the insulation board can not only be installed easily, but can also be fixed accurately. The provided ventilation recess 11 has the effect of reliably forming a ventilation gap with the base.

In addition, since the heat insulating board is made of foamed synthetic resin, it not only has excellent heat insulating properties, but is also easy to manufacture.
It is lightweight and convenient to transport and handle.
