Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for assembling an all-weather temporary roof in which the construction of a building to be constructed is covered with a roof frame capable of ascending so that construction can be performed without being affected by the weather.

[0002]

2. Description of the Related Art In recent years, an all-weather temporary frame has been proposed as a temporary scaffold for the construction of RC high-rise buildings.
This temporary frame is constructed by erecting a plurality of temporary columns around the building to be constructed and supporting a roof frame on the upper part between the temporary columns. By lifting the roof frame while supporting the pillars upward, the construction can be performed without being affected by the weather. An overhead crane is arranged on the lower surface of the roof frame, and materials lifted by an elevator or the like are transported to each part through the overhead crane and assembled.

[0003]

However, in such a conventional all-weather temporary roof, when the roof frame is constructed, first, the temporary pillars are set up in advance and the scaffold is assembled. The roof frame is to be assembled on the roof.

Therefore, in order to construct the roof frame, scaffolding must be built up to a high place, and the assembling and removing work after completion of the constructing are required, and extra work and labor are required. Further, since the roof frame is assembled at a high place using scaffolds, workability may be deteriorated and accuracy may be deteriorated, and it is necessary to secure safety in high place work. Therefore, there are problems that the construction cost is increased and the construction period is prolonged.

In view of the conventional problems, the present invention provides a method for assembling an all-weather temporary roof in which the work of a high place is abolished by constructing the roof frame near the ground surface. To aim.

[0006]

In order to achieve the above object, the present invention has a structure in which a building to be constructed is connected to or adjacent to a planned construction position and successively connected upward in accordance with an increase in the construction height. Along with erection of a temporary pillar that can be added, a climbing mechanism is attached to this temporary pillar, and a roof frame that covers the entire top surface of the building is supported by this climbing mechanism. In an all-weather temporary roof that climbs up the climbing mechanism while continuing to rise upwards, thereby raising the roof frame,
After the climbing mechanism is attached to the temporary support column in a state where the ground around the temporary support column is excavated, the roof frame is constructed at a low position on the ground surface or close to the ground surface and supported by the climbing mechanism. Characterize.

In the method for assembling an all-weather temporary roof according to the present invention by the above method, when the roof frame is constructed, the ground around the temporary columns is excavated so that the roof frame is placed on the ground surface or the ground. It is possible to build in a low position close to the surface. Therefore, since it is not necessary to provide a scaffold for constructing the roof frame, the construction work can be performed safely and quickly, and the workability can be greatly improved.
