Abstract

PROBLEM TO BE SOLVED: To provide a heat insulation material mortar direct coating system capable of realizing reduction in a material and labor-saving of labor by completing an outer wall by directly coating mortar in a wooden fibrous heat insulation material without constructing a furring strip in an external part, and capable of also realizing even safety by providing both fireproof performance on the wooden fibrous heat insulation material.SOLUTION: A heat insulation material mortar direct coating system is constituted by constructing an external finishing material (direct coating exclusive mortar) 2 on a wooden fibrous heat insulation material (1), by constructing the wooden fibrous heat insulation material (1) on its outdoor side (the outside), by arranging a structural face bar on the outdoor side.SELECTED DRAWING: Figure 1

Description

The present invention relates to exterior construction of a wooden building.

The exterior construction of the conventional heat insulation method in conventional wooden construction is a method of driving the outer edge of the body edge into the thermal insulation that is externally installed to insulate the house, and then constructing the exterior material such as siding board or mortar on the outer edge of the body. Limited.

Many of the heat insulation materials used as external heat insulation are petroleum-based heat insulation materials. Petroleum-based heat insulating materials are disadvantageous in that the raw materials are easily burned due to oil and generate harmful gases when burned. Therefore, heat insulating materials that are resistant to fire and do not emit toxic gases even in the event of a fire are used.

The trunk edge may be used for exterior construction or for the purpose of providing a ventilation layer. However, there is a drawback that corrosion will be a concern in the future. Use the right materials.

An object of the present invention is to provide a heat-insulating mortar direct coating system in consideration of the conventional drawbacks described above, in consideration of building a safe and long-lasting house, reducing materials, and saving labor.

In the present invention, a wooden fiber heat insulating material is applied as an outer heat insulating material that does not hinder the movement of water vapor.

A special mortar that can permeate water vapor is applied directly to the wooden fiber insulation.

As is clear from the above description, the following effects can be obtained from the present invention.
(1) The wood fiber heat insulating material constructed as an external heat insulating material can be directly applied with a special mortar, so it is possible to complete the exterior without the need for a torso, and there are concerns about future corrosion. Construction can be done without using any material.

(2) Furthermore, since the wooden fiber heat insulating material and the exclusive mortar are materials that allow only water vapor to pass therethrough, they can be constructed without providing a ventilation layer by the trunk edge.

(4) From the above, material reduction and construction processes are reduced, realizing cost reduction.

(5) In addition, the thermal insulation mortar direct coating system, in which dedicated mortar is directly applied to the wooden fiber insulation, succeeded in a fire prevention experiment based on the Building Standards Act in 2004. For the first time in Japan, mortar is directly applied to a wooden fiber insulation to allow its use as an outer wall.

(6) From the above, it is more resistant to fire than petroleum-based heat insulating materials and difficult to burn even in the event of a fire, so the progress of the fire is delayed, and toxic gas is not emitted, realizing safety to people and the environment.

It is wall sectional drawing of the outer peripheral part by the shaft assembly method of this invention.

Hereinafter, embodiments of the present invention will be described based on the drawings.
FIG. 1 is an example showing a cross-sectional view of the structure of a wall serving as a partition on the outdoor side in a building that employs the frame construction method of the present invention.

The structure of the outer wall is basically the conventional shaft assembling method, and the intermediary pillars 5 are appropriately incorporated between the pillars 4 and the solid wood 3 is nailed in place of the wall boards and the structural plywood.

All the wood fiber insulation 1 made of natural material is nailed so as to cover the outside of the solid wood 3.

Then, an external finishing material (direct coating mortar) 2 is applied to the wooden fiber heat insulating material 1.

The wooden construction is generally a frame construction method and a frame construction method, but the present invention can be applied to any wall structure.
