Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a steel frame (hereinafter referred to as S
The present invention relates to a folding structure of an S-structure frame, a method and an apparatus for folding a frame having a steel frame structure, which can be easily installed using the foldable frame.

[0002]

2. Description of the Related Art Hitherto, various configurations in which a frame of a temporary structure is made freely foldable have been proposed. For example, in the opening and closing building block for temporary building disclosed in Japanese Patent No. 2872995, a structure in which a roof shingle is mounted on front and rear wall slabs is shown. In this structure, the roof panel and the front and rear wall panels are connected to each other so as to be freely opened and closed. As a method of installing this structure, a method using two wires is adopted, and a second wire for lifting the roof shingle together with the wall slab and a first wire for lifting only the roof shingle are operated. The procedure of these wire operations is as follows: first, the roofing board and the front and rear wall boards are held in a suspended state by the second wire, then the roofing board alone is lifted by the first wire, and the front and rear wall boards are vertically moved by their own weight. After opening to the position, it is the work of fixing it with a sword and installing it in a predetermined position.

[0003]

Various constructions in which a frame is freely foldable, such as a conventional opening / closing building block for a temporary building, have been proposed for a temporary building. However, such a structure has been proposed for a building structure using a steel frame structure. It was not usable. For example, in the above-mentioned temporary building opening / closing building block, it is possible to place a roof shingle on the front and rear wall boards as a temporary building, but a building with a steel frame structure that meets the building standard of S structure is used. It is impossible to configure. That is, in order to form a rigid frame structure in S-structure, it is necessary to make the joint (joint) between the column and the beam a rigid joint. For this reason, in the S structure, a diaphragm is formed at the connection to strengthen the structure. However, in the conventional frame structure which is freely foldable, since the opening is freely opened and closed, it is difficult to provide a diaphragm to strengthen the opening. Therefore, the conventional foldable frame structure has a structure that cannot be used to construct a steel frame structure, even though it can be used for temporary construction.

[0004] In addition, since the steel frame structure using the connection provided with the diaphragm is much heavier than the temporary building, a method of operating two wires to lift each part separately is not used. , Can be a very dangerous task. In other words, at least two cranes are required to operate the first wire and gradually lift the roof shingle while fixing the second wire that suspends the whole via the wall panel. These two operations are extremely difficult operations compared to one operation. In addition, when one object is hung by two cranes, the load applied to each of the cranes changes gradually, so that care must be taken in the operation of maintaining the balance of each crane. Performing such an operation with a crane used for general construction would be extremely difficult and dangerous.

Accordingly, the present invention has been made to solve the above-mentioned problem, and it is possible to construct a building having a steel frame structure, and it is possible to easily and safely install the building with one crane. It is an object of the present invention to provide a folding structure and an installation method of a frame for S structure which can be provided.

The wall frame P is disposed at a position such that when the deployment wire 1 is lifted by the crane C, an S-shaped frame composed of the roof frame Q and the pair of wall frames P is formed.

[0008] With such a structure for folding the S-frame, the frame used for the S-frame can be compactly folded to save space for storage and transportation, and to increase work efficiency.

The third means is to arrange a pair of wall frames P at both ends of the roof frame Q so as to be swingable,
In the method of unfolding the wall frame P folded on the lower surface of the vehicle with the crane C and installing the folding frame,
The development wire 1 is connected from the roof frame Q to each wall frame P, and each development wire 1 is lifted by the crane C via the pulley 2 to open each wall frame P vertically, and installed with each wall frame P open. It is to move to the position and install it.

A fourth means is to provide a method of installing a folding frame, in which wheels 4 which are removably mounted on the lower end of the wall frame P are lifted by a crane C via pulleys 2 on each deployment wire 1. When each wall frame P is opened vertically, there is a method in which the wheels 4 are deployed while being in contact with the iron sheet 5.

According to the installation method of the present invention, not only can the S-construction be easily assembled, but also the used S-construction can be easily dismantled and relocated, so that the folding frame can be recycled and the material can be recycled. Costs can be streamlined.
