Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall which is an exterior wall of a general building such as a house, an office building and a factory, and a method for manufacturing the curtain wall.

[0002]

2. Description of the Related Art Curtain walls are made of metal or PC, for example.
It is a board with a finishing material attached to the surface of the wall body made of concrete, and is attached to the exterior as the exterior of the building with fasteners such as anchor bolts.

This fastener is attached to a board-shaped wall body in advance, but since the tip projects from the wall body,
In a curtain wall using C concrete, fasteners are arranged so as to project from the upper surface when concrete is poured. For this reason, the flat punching method for each sheet is adopted as the manufacturing method.

[0004]

The method of producing each sheet by the flat punching method is not good in productivity, and when it is used as an exterior covering wall of a building, it is desired to have heat insulation property. Since a structure with built-in material is costly as a connecting material to integrate it with the plate bodies on both sides, there is no established curtain wall with a built-in heat insulating material in the past, and it has good heat insulation. There wasn't.

Further, since the entire wall body is made of PC concrete, the weight becomes large and it is not easy to handle during storage, transportation, construction, etc.

An object of the present invention is to eliminate the disadvantages of the above-mentioned conventional examples and to provide a curtain wall using PC concrete,
It has heat insulating properties, the fasteners do not project, and many sheets can be manufactured at the same time without relying on the flat hammering method, improving productivity, reducing weight, and easy to handle during storage, transportation, and construction, and cost reduction It is an object of the present invention to provide a curtain wall that can be manufactured and a manufacturing method thereof.

[0007]

In order to achieve the above object, the present invention provides a manufacturing method in which the interior of a molding tank is partitioned by a plurality of vertical partition plates to form a flat space in parallel, and the flat space is provided in the space. A three-dimensional welded wire net with fasteners and a built-in heat insulation board is arranged vertically, and a material such as concrete or mortar is cast in the remaining space formed on both sides of the three-dimensional welded metal net to form an outer surface material and an inner surface material. The gist is that it is formed integrally with a three-dimensional welded wire mesh.

In the vertical partition plate, an elastic mat for patterning and a surface heating element for high temperature curing are arranged inside the partition plate, and the fastener is composed of anchor bolts, concrete or mortar. A melting member is placed around the tip of a bolt part that is embedded with the inner surface material formed by casting the material, and after the inner surface material is solidified, the melting member is melted to form a space for mounting the nut here. The main point is to do.

As a structure, the interior of the molding tank is partitioned by a plurality of vertical partition plates, flat spaces are arranged in parallel, and a three-dimensional welding wire net containing a fastener and a heat insulating board is vertically arranged in the space, and A material such as concrete or mortar is placed in the remaining space formed on both sides of the three-dimensional welded wire mesh to form the outer surface material and the inner surface material integrally with the three-dimensional welded wire mesh, and a zipper is provided and a heat insulation board is built in. The gist is that an outer surface material and an inner surface material made of a material such as concrete or mortar are integrally arranged on both sides of a three-dimensional welded wire mesh.

According to the first aspect of the present invention, the interior of the molding tank is divided by a plurality of vertical partition plates to form a flat space in parallel, and a three-dimensional welded wire net containing a heat insulating board is arranged therein. In addition, concrete is cast to form the curtain wall, so that a plurality of curtain walls can be manufactured at the same time.

Further, since the fastener is also arranged in the space for placing concrete, it does not project from the inner surface material.

According to the second aspect of the present invention, in addition to the above-mentioned action, the surface of the curtain wall can be easily patterned by arranging an elastic mat for patterning inside the partition plate. In addition, the surface heating element allows high temperature curing,
Quick demolding is possible and the rotation rate of the molding tank is improved.

According to the third aspect of the present invention, in addition to the above-mentioned action, even if the fastener is embedded in the inner surface material by driving a material such as concrete, the melting member is arranged so that the nut can be attached. A space can be secured and it can be attached to a building.

According to the fourth aspect of the present invention, since the heat insulating board is built in, the heat insulating property is excellent and the weight can be reduced by the thickness of the heat insulating board. In this case, for the disposition of the heat insulating material, it is possible to suppress the production cost by using a three-dimensional welded wire net with a built-in heat insulating board that can be produced in a factory.
