Description

TECHNICAL FIELD The present invention relates to a structure of a joint portion of a heat insulating wall type structure.

[Conventional technology]

Overseas, many buildings are already constructed in which walls and floors are constructed by spraying mortar or concrete onto a three-dimensional wire mesh panel having a heat insulating material as a core material.

The applicant has also filed several applications regarding inventions relating to this type of building.

[Problems to be Solved by the Invention]

However, the conventional building of this type has extremely good heat insulation, but is different from the so-called ramen structure in terms of strength.

Therefore, although there is no problem in countries with relatively few earthquakes, it cannot be said that buildings are safe in earthquake-prone countries such as Japan.

In particular, it has been pointed out that the joints between the walls on the upper and lower floors and the joints between the walls on each floor and the floor are weak points in terms of strength.

The present invention has been proposed in order to solve the above-mentioned conventional problems, and in particular, an adiabatic wall type structure that can be sufficiently applied even in an earthquake country such as Japan by making an integral joint of joints. The purpose of the present invention is to provide a structure of a joint in the above.

[Means for Solving the Problems]

The present invention relates to a structure of a joint portion of a heat insulation wall type structure, in which a heat insulation panel is arranged between two parallel metal mesh panels, and a three-dimensional metal mesh panel with a heat insulating material is formed by connecting the metal mesh panels with a lattice material. The outer and inner walls of the outer wall of each floor are constructed by spraying concrete or mortar on both sides of the three-dimensional wire mesh panel with heat insulating material, and the PC panel is integrated with the heat insulating panel on one side of the three-dimensional wire mesh panel with heat insulating material. Insulated wall type structure in which the floor of each floor is constructed by laying a half-PC floor panel that is formed in a concrete manner with the PC panel surface facing down and placing concrete or mortar on the half-PC panel. In the above, by connecting a plurality of connecting rebars to the joints of the outer wall and the inner wall of the upper and lower floors, and installing a connecting wire mesh at the joints of the outer wall and the inner wall of each floor and the floor, It is intended to achieve.
