JPH0531838A - Architectural material provided with heat-insulating and waterproof function - Google Patents

Abstract

PURPOSE:To obtain the architectural material provided with a heat-insulating and waterproof function by causing the waterproof and heat-insulating member in which a number of air-enclosed parts are projected to intervene between motar-layers on both sides of the base made of plastic. CONSTITUTION:While building material is provided with the base 3 made of flexible plastic, another plastic sheet 4 is stuck onto the surface of said base 3. The positions except the bonded parts 4a stuck to the base 3 in the plastic sheet 4 are separated from the base 3, and air-enclosed parts 4b are formed between said separated parts and the base 3. Further, a plastic sheet 6 is stuck also onto another flexible base 5, and air-enclosed parts 6b are formed at the positions except its bonded parts 6a. Then, the base 3 is closely stuck onto the base 5 mutually, and a waterproof and heat-insulating member (a) is constructed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building material having both a heat insulating function and a waterproof function.

[0002]

2. Description of the Related Art There has been no building material having both heat insulating and waterproof functions up to now, but the reason is as follows. Since the conventional heat insulating material is made of, for example, glass wool or organic foam, once it contains water, its heat insulating function is almost lost. Therefore, such insulation is
Originally, it does not have a waterproof function, and if you dare to use it as a waterproof material, you will quickly lose the heat insulating effect.

Further, since the conventional waterproof material is designed so as to prevent only the permeation of water, there is no one having a heat insulating effect by itself. If anything, most of them are made thinner so that they can be easily installed. For the above reasons, up to now, there is no one that has both a heat insulating function and a waterproof function.

[0004]

As described above, there has been no heat insulating and waterproof function so far. Therefore, heat insulating and waterproof must be installed separately. There was the problem of not becoming. An object of the present invention is to provide a building material that has both a heat insulating function and a waterproof function.

[0005]

The present invention is characterized in that waterproof heat insulating members formed by projecting a large number of air-filled portions are provided on both sides of a plastic base between the mortar layers.

[0006]

In the present invention, the waterproof heat insulating member made of plastic exerts the waterproof function. Moreover, this waterproof insulation member has
Since a large number of air-filled portions are projected, this air-filled portion exhibits a heat insulating function.

[0007]

By using the building material of the present invention, both the heat insulating function and the waterproof function can be exhibited at the same time, so that it is not necessary to separately install both the heat insulating function and the waterproof function as in the conventional case. Further, since the air-filled portions are projected on both sides of the waterproof heat insulating member, the surface area thereof is increased. Moreover, since the mortar enters between the air-filled portions, the adhesive strength between the mortar and the waterproof / heat insulating material is increased in combination with the large surface area.

[0008]

EXAMPLE In the illustrated embodiment, a waterproof heat insulating member a is interposed between the mortar layers 1 and 2.
The specific configuration of is as follows. A flexible plastic base 3 is provided, and another plastic sheet 4 is attached to the surface of the base 3. However, the plastic sheet 4 is separated from the base 3 at portions other than the close contact portion 4a that is in close contact with the base 3 to form an air filled portion 4b between the base 3 and the base 3. Further, the plastic sheet 6 is also attached to the flexible base 5 different from the above, and the close contact portion 6a is formed.
The air-filled portion 6b is formed at a location other than the above. Then, the bases 3 and 5 are closely attached to each other to form the waterproof heat insulating member a.

As described above, since the air enclosures 4b and 6b are projected on the surface of the waterproof heat insulating member a, the surface area thereof is increased. Moreover, since the mortar enters between the air-filled portions 4b and 6b, the adhesive force between the mortar layers 1 and 2 and the waterproof heat insulating member a also becomes strong in combination with the large surface area.

In the building material as described above, the waterproof heat insulating member a made of plastic functions to exert a waterproof function.
Moreover, this member a has a large number of air enclosures 4b and 6b.
Since it is projected, the air in it exerts a heat insulating effect.

If this building material is used, for example, for an outer wall, it can exhibit both the functions of waterproofing and heat insulating at the same time. Therefore, it is not necessary to separate waterproof construction and heat insulation construction as in the conventional case. If this building material is used around the basement, the temperature of the basement can be kept more constant.
