Description

[Detailed explanation of the idea] The present invention relates to wall structures in houses.

(Prior art and purpose and structure of the present invention) A heat insulating material such as glass wool mat is filled between the base structural members of the wall such as columns and studs, and the external wall material is constructed on the outside of the base structural material, and the internal wall material is constructed on the internal side. is,
It was considered a wall structure.

In addition, in the case of an external mortar wall, after constructing a base material such as lath on the pillars and studs, staple a waterproof sheet over the base material and lath netting, and then apply mortar to the surface. was.

As a result, condensation tends to form inside the walls due to the temperature difference between the outside and inside, and the condensed water can also seep into the insulation material, causing the insulation material itself to slide downward, or the outside or inside wall materials to absorb moisture and expand. Warping occurs due to

Furthermore, there are other problems such as corroding base structural materials, base materials, staples, etc., reducing the durability of the house, and causing cracks and peeling of mortar walls, reducing the heat insulation effect of the heat insulating material.

However, in order to solve these problems, a system has already been proposed in which a support net with protrusions is inserted into the air cycle space, as in Japanese Patent Publication No. 57-49692. However, this proposal has problems such as the insulation layer slipping off due to the sufficient bonding between the insulation material and the support net, and the dimensional design of the support net being extremely difficult considering the expansion and contraction of the structural materials. leaving a mark.

The present invention aims to solve the problems of conventional wall structures as described above.

(Description of Embodiments) In the drawings, reference numeral 1 denotes a base structure material such as a pillar or a stud, and an outer wall 2 is formed on the outer surface of the base structure material 1. The outer wall 2 is made of a waterproof sheet 2a such as a synthetic resin film or sheet, asphalt felt, or a laminated film with a synthetic resin film as a core layer and kraft paper laminated on one or both sides of the core layer, as required, on the outer surface of the base structure material 1. Exterior wall materials,
It is formed by the exterior wall base material.

Exterior wall materials here refer to those made of inorganic, organic, inorganic-organic mixed, or composite plate-like materials whose surface is optionally coated in advance, or those made by applying a coating after the plate-like material is constructed. say.

In addition, external wall base material is one that is immediately coated with a wall coating material such as mortar, or a plate-like material is constructed and then a base sheet such as lath mesh is pasted through a waterproof sheet, and then mortar or other coating material is applied. One example is a wall that is coated with a wall coating material.

The exterior wall material and the exterior wall base material are fixed onto the base structure material 1 directly or through a waterproof sheet by gluing, nailing, or the like.

A plurality of linear objects 3 provided with locking protrusions 6 at arbitrary locations are stretched and fixed between the base structural members 1 and 1 using a stapler or the like at an appropriate distance from the outer wall 2.

The linear object 3 is made of synthetic resin thread, glass fiber thread, metal wire, etc., and barb-like locking protrusions 6 are provided at arbitrary locations around it as shown in FIG.

The linear object 3 prevents the heat insulating layer 4 installed between the walls from coming into contact with the back side of the outer wall, and also sticks and holds the heat insulating material such as glass wool forming the heat insulating layer 4 with barb-like locking protrusions 6. Even if water is absorbed by the heat insulating material due to penetration of rainwater, the heat insulating material itself will not slide downward. In addition, since the locking protrusions 6 are provided at arbitrary locations around the linear object 3, even if the linear object 3 is twisted when the linear object 3 is stretched, the barb-shaped locking projections 6 will be securely attached. It sticks to the insulation layer 4.

A glass wool mat with a moisture-proof layer 4a formed on at least one side as necessary between the base structural members 1;
A heat insulating material such as a synthetic resin foam is inserted and fixed with its moisture-proof layer side facing the indoor side, and a heat insulating layer 4 is provided.

The heat insulating layer 4 is spaced apart from the outer wall 2, and the linear material 3 is
An air cycle space is provided between the heat insulating layer 4 and the outer wall 2, which communicates the underfloor space and the attic space without being in direct contact with the outer wall 2.

On the other hand, if necessary, a waterproof sheet 7a such as a synthetic resin film or sheet, asphalt felt, or a laminated film with a synthetic resin film layered as a core layer and kraft paper laminated on one or both sides of the core layer is applied to the inner surface of the base structure material 1. The inner wall 7 is formed, such as an inner wall material and an inner wall base material. The interior wall material referred to here refers to a material made of inorganic, organic, inorganic-organic mixed, or composite plate material whose surface is optionally coated in advance, or a material made by coating the plate material after construction. .

An example of an inner wall base material is one on which a paint material such as sand wall, fiber wall, etc. is applied directly or after plastering.

The inner wall material or the inner wall base material is fixed onto the base structure material 1 directly or via a waterproof sheet 7a.

In this way, a wall structure is obtained in which an air cycle space 5 is formed between the heat insulating layer 4 and the outer wall 2, and between the base structural material 1, which communicates the underfloor space and the attic space.

In a narrow space such as the air cycle space 5, a laminar flow is generated in which air having different temperatures forms layers and flows as an upward or downward air current. Then, on the wall surface where the sun is shining, the air in the air cycle space 5 is warmed through the outer wall 2, rises, and flows into the attic space. At the same time, the cold air in the underfloor space is sucked into the air cycle space 5 and is heated sequentially in the attic space. Flow into space.

On the other hand, on the surface of the outer wall 2 on the side that is not exposed to the sun, the air in the air cycle space 5 cools down and flows into the underfloor air, and along with this downdraft, the warm air in the attic space flows into the air cycle space. The air is sucked into the air cycle space 5 and flows into the underfloor space while warming the inside of the air cycle space 5.

Furthermore, when a vent is provided in the attic, warm air in the attic space is released to the outside, and cold air in the underfloor space is naturally circulated into the attic space through the air cycle space.

(Function and effect of the present invention) The outer wall 2 side of the outer wall 2 and the heat insulating layer 4 is covered with the base structure material 1.
Since it is suppressed by the linear object 3 stretched between them, it does not protrude and block the gap in the air cycle space 5.

In addition, the linear object 3 has locking protrusions 6 at arbitrary locations around the periphery.
Since the heat insulating material is stuck and held by the projections, the heat insulating material itself will not fall off. In addition, since the locking protrusions 6 are provided at arbitrary locations around the linear object 3, even if the linear object 3 is twisted when stretching the linear object 3, any of the locking projections 6 will be securely attached to the heat insulating layer 4. It sticks.

Therefore, the flow of air rising and falling within the air cycle space 5 is ensured, and the heat insulation effect is sufficiently exhibited.
