Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing device for mounting an outer wall material which enables work without an external scaffold, and a method for stacking middle and high-rise buildings using the fixing device.

[0002]

2. Description of the Related Art The main structure of buildings such as buildings is
Generally, it is roughly classified into SRC structure (steel frame reinforced concrete structure), S structure (steel frame structure), RC structure (reinforced concrete structure) and the like.

Further, as one form of a building construction method,
2. Description of the Related Art Conventionally, there is a stacking method for building while stacking each floor from the lower floor to the upper floor, and the floor surface of each floor is formed by placing concrete in order from below and stacking.

On the other hand, in recent years, the outer wall of a building has been previously
There is a half-PC construction method that uses a half-PC board manufactured in factories, etc., and the time required for on-site work that is affected by weather etc. is reduced as much as possible to shorten the construction period and realize overall cost reduction. There is.

Such a half-PC board is manufactured in a factory or the like on the substantially outer half of the wall, and is preliminarily subjected to external finishing such as tile and stone driving, spraying, etc. to ensure stable quality and production capacity. You can

However, when a half-PC board is used in a laminated construction method, particularly in the case of a building having a discontinuity on the outer wall surface of the building due to a handrail part of a veranda or a continuous window, the half-PC board is used for the building. Metal fittings and the like to be supported on the side are required, and usually, metal fittings for holding a half-PC board are preliminarily attached to the steel frame of a building.

Therefore, the half-PC boards for the balcony and waist wall that are attached to the beam portion have not been adopted for RC constructions that do not use steel frames.

For example, as a lamination method using the above-mentioned half-PC board, FIGS. 17 (a), (b) to FIG. 19 (a),
There is one as shown in (b).

This is a half PC board 10 on the outer wall of the continuous window type.
Although the case where 0 is attached is shown, the half-PC board 100 has a down wall portion 100a and a waist wall portion 100b formed on the upper and lower portions, respectively, and upper and lower wall portions 100a, 100b are connected by a connecting portion 101. A half PC board 100 is formed by connecting them in series.

The half-PC board 100 is mounted on the floor 10 of the standard floor n.
2 and the steel frames 103 and 104 of the floors of the floor immediately above the standard floor n + 1, which are to be the floors, are attached via the metal fittings 105 and 106, and then the floor surface 107 of the floor immediately above the floor n + 1 is formed by concrete casting.

After the half PC board 100 is attached, the connecting portion 101 of the half PC board 100, which is to be the window portion, is disassembled and removed (FIG. 18) to form the window portion.

[0012]

However, the above-mentioned lamination method using a half-PC board still has the following problems.

That is, as described above, in order to form the continuous window portion, the connecting portion 101 is attached after the half PC board 100 is attached.
However, heavy equipment and external scaffolding were required for such dismantling work.

This is unsuitable for construction in urban areas where there is not enough space between adjacent land, and moreover, disassembled concrete pieces and the like may fall, which is dangerous even if it is a low-rise building. It was difficult to use for medium-rise buildings.

Further, waste materials such as dismantled concrete pieces are generated, and it takes a lot of time to dispose of the waste materials, which is not an efficient work.

The present invention is a fixing device for mounting a half-PC board capable of solving the above-mentioned problems, and
It is intended to provide a method of stacking high-rise buildings.
