Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to external heat insulation for energy-saving houses and the like, mainly in wooden construction.

[0002]

2. Description of the Related Art Conventionally, the exterior wall coating method has been used in which sand is the main aggregate, and a material containing cement and an admixture is kneaded with water to form a mortar. The outer wall is completed by coating the surface of the outer wall with a coating base, and the outer wall is less heat insulating. Therefore, a heat insulating material is attached to the inner surface of the outer wall.

[0003]

The conventional coated mortar is a heavy material and has a small heat insulating effect, and is not suitable for thick coating. The outer wall mortar coating wall alone, including the lath felt and lath base sheet, has a sufficient heat insulating effect. Insulation material is attached to the inner surface of the outer wall of the building with many irregularities, resulting in poor construction accuracy and construction efficiency.

[0004]

[Means for Solving the Problems] Development of a lightweight, non-combustible and excellent heat insulating material for the outer wall coating, making a heat insulating and waterproofing sheet as a base sheet, having heat insulating and waterproof performance, outer wall coating Effective wall insulation is achieved only by wall construction, eliminating the problem of installing insulation material inside the outer wall.

The compounding perlite of the wall material to be developed is made of natural stone as a main aggregate, and the main aggregate is perlite.
It is a material that does not use sand as the main aggregate and is made by mixing cement and powdered resin.

A hardened, dry, light, non-combustible and heat-insulating compounded perlite is used as a lightweight, non-combustible, heat-insulating and anti-condensation material according to the compounding design for outer wall, inner wall and roof applications. create.

The heat-insulating waterproof sheet is produced by laminating an aluminum vapor-deposited film on the back of a foamed polyethylene sheet and a non-woven fabric having a water-absorbing property.
Make a sheet with good workability and heat insulation and waterproof effect.

DETAILED DESCRIPTION OF THE INVENTION Embodiments of the invention will be described. In order to obtain the external heat insulation effect, mainly by applying the coating to the outer wall of the wooden construction,
Prior to lathing, the heat insulation, waterproof sheet, width, and length developed in place of the conventional lath felt and lath foundation sheet on the outer wall foundation plate are made into a scroll of a size suitable for on-site construction, and After stopping, lath tension is applied to form a painted wall base with heat insulation and waterproof effect.

[0009] Next, on the finished coating wall base, add a prescribed amount of water and a special admixture for adjusting the construction softness to the compounded perlite for the outer wall, and knead with a mixer to make a coating wall material. The surface is adjusted with a wooden trowel when drawing water to improve the adhesion of the next topcoat, wait for the dry state of the undercoat that can be overcoated, and then finish the topcoat with a metal trowel pressing finish, becoming a light wall coating material. A thick, non-combustible outer wall and painted wall that can be applied thickly and are effective for external heat insulation.

The completed outer wall is a wall having a small shrinkage rate and a small number of cracks, and can be sufficiently applied as a spray finish base.
Although it has a high heat insulation effect, it has high water absorption, so for the spray finish, use elastic spray with excellent waterproofness.

The compounded perlite for the inner wall is thinly coated on a lath board to give a gold trowel-pressing finish, and a wall excellent in heat retention and dew condensation prevention can be formed as a paste-based finish wall material or a cloth bonding base.

The compounded perlite for roof is a light-weight, non-combustible, heat-insulating material that is applied on a perforated base plate in a wooden construction to form an insulating layer on the roof surface, which floats on water after drying. It is also effective in preventing dew condensation on the back of the roof, and if the roof has an airway and has a double structure to enhance the heat insulation effect, the airway tree is firmly attached by sandwiching the heat insulating layer on the tree as the lower roof, and floating on it. Can be used as a conventional roofing with a main plate.

[0013]

Since the present invention is constructed as described above, it has the following effects.

With the development of compounded perlite and heat-insulating and waterproof sheet, the heat insulation of wooden construction is achieved by the outer wall coating method, which is energy saving by the outer heat insulation effect and fire prevention of the outer wall by the noncombustible heat insulating material.

It can be used as an inner wall lath board surface, a paste-based clay wall and a cloth-applied base to finish the wall effective in dew condensation and heat insulation.

[0016] It can be applied to the roof base plate to form a heat insulating layer on the outside of the roof surface, so that the roof surface can be insulated and the attic condensation can be prevented.

In the field construction, the construction is performed outside the building, and it is possible to eliminate the installation of the heat insulating material from the inside, which has better construction accuracy and workability than the construction on the outer wall and the inner wall surface.

By using the compounded pearlite on the inner wall of the RC structure, it is possible to enhance the heat insulating effect and prevent dew condensation.
