Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated construction sheath insulation structure,

The present invention relates to a construction method of a building external wall heat insulation material on the outer wall of a building, which is beautiful by embodying the wall of various buildings in a prefabricated manner, and prevents permanent penetration from the outside and provides semi-permanent construction for protecting the building from external impact such as earthquake The present invention relates to a construction method of an outer wall of a building.

A number of walls are formed between the ceiling slab and the floor slab on the inside and outside of the building to divide and separate the rooms and other spaces. In the case of the outer wall buildings, not only can the interior and exterior of the building be distinguished, It can be said that it is generally installed.

After the wall of such a building has been constructed, it is provided with a beauty in the appearance of the building. In order to protect the wall layer, a stone panel made of natural stone or artificial stone such as marble or granite, And aluminum panels, ALC, and den.

In this case, the angle of mounting the finishing material along the reference line set on the wall may be firstly set at a predetermined interval, the heat insulating material may be attached, and the outer finishing material may be fixed to the outer end of each angle. In case of applying the wet method, it is necessary to apply the silicone to the joint portion between the external finishing material and the heat insulating material, the joint portion between the external finishing materials and the joint portion between the external finishing materials, Can be wet-bonded using a glass fiberglass mesh made of a blend of water and water.

In the conventional method of installing the exterior finishing material, silicon is mainly used in the joint portion of the member in the case of the dry method, and in the summer, silicon oil is melted due to high temperature and penetrates into the pores of the stone panel, And discoloration. In winter, condensation occurs due to the hermeticity between the wall and the finishing material due to silicone, which seriously affects the appearance of the building. In addition, it is necessary to repair the silicon in a period of about 3 to 4 years And the maintenance cost of the building is greatly increased.

In addition, in the case of the wet method, since water and mortar are mixed and filled in the joint part filling between the finishing materials at the construction site of the building, there is a difficulty in working in the winter, and it is difficult to uniformly apply the entire outer wall by applying the glass fiber mesh There is a problem in that defects due to peeling and cracks are caused in the area where the construction is insufficient, and the post-processing cost for processing the defect is increased.

In addition, the method and the method for installing the exterior finishing material do not have a structure capable of absorbing and dispersing an external force generated from a strong external impact applied to a building due to natural disasters such as an earthquake or a typhoon, The damage of the building itself is seriously damaged.

On the other hand, in Korean Patent No. 10-0867273, the exterior of a wall is finished with a lightweight, high-strength cement panel, and a foamed heat insulating material is injected between the wall and the finishing material to integrate the finishing of the inside and outside walls of the building, A construction method of a building wall having excellent insulation performance, as well as excellent earthquake resistance, fire resistance and sound insulation performance is disclosed.

In the case of the above-mentioned patent, the hollow extrusion-molded cement panel is fixed to the panel support on the wall of the building, and the joint portion is sealed. Then, the injection port for injecting the water soft foam is punched And an aqueous soft foam is injected through the injection port between the wall and the cement panel so as to be foamed therein to secure a heat insulation layer between the wall and the panel.

However, the technique disclosed in the patent document is a series of very complicated processes for inserting a cement panel to a wall of a building and then injecting an aqueous soft foam between the wall and the cement panel to insulate the building, It is pointed out that the construction panel joined to the frame of the wall is detached by the fixing clip when the foam volume of the waterproof flexible foam injected into the wall between the wall and the cement panel is increased.

In addition, since the fixing clip is fixed to the panel support fixed to the wall by using a fastening means such as a screw, a bolt, or the like, it is necessary to use an attachment tool.

Korean Patent Laid-Open No. 10-2014-0137273 (published on December 04, 2014) Korea Patent Registration No. 10-0867273 (registered on October 30, 2008)
