Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting system for performing all-weather construction of building structures such as buildings and condominiums.

[0002]

2. Description of the Related Art Conventionally, as a construction method of an all-weather building structure, Japanese Patent Application Laid-Open No.
As disclosed in JP-A-107038, the core portion 1 is constructed by an automatic ascending formwork including a temporary support, a formwork portion, a jack and a bracket, and at the same time, the column 1 of a building is constructed.
The jack 12 is also set up at the place where 3 is erected. Next, after preliminarily constructing the core portion 1 for two layers, the beams 14 and columns 13 for three layers are simultaneously constructed from the top of the building, and the bottom formwork for columns,
A column formwork is provided, and concrete for the columns 13 and the slabs 24 is cast. At the stage where the pillars 13 have hardened to a state where they can become independent, the jacks 12 and the like are extended to push up the frame by one layer, and the construction work on the lower floor is sequentially continued. I have. As another method, as shown in JP-A-5-25864, after constructing a pillar 10 of a building, an operation of raising a floor slab S along the pillar 10 is sequentially and repeatedly performed. The floor slabs S are respectively arranged on the floor of each floor. In such a construction method of the building frame, the step of raising the floor slab S is performed by changing the floor slab 5S on the top floor to the floor slab 1 on the next floor side.
Step S is performed in order. There are known construction means for raising the floor slab S while supporting the floor slab S by the lifting device 2 arranged on the lower surface of the floor slab. As another means, as shown in Japanese Patent Publication No. 7-33689, a skeleton of one floor is intensively constructed at the ground level, and after completion of the skeleton construction of one floor, the pillars of the skeleton are raised upward by the floor height. The building is constructed by repeating the push-up process, in which case a flange having a push-up pin hole and a fixing pin hole is attached to the pillar, and a pin engageable with the push-up pin hole is provided. There is known a construction means for disposing a center hole jack and a skeleton holding device having a pin that can be engaged with the fixing pin hole around the column, and pushing up the column of the skeleton with this.

[0003]

The following characteristics are recognized in the above-described building means of the conventional building structure. (A) Work can be performed in all weather and is not affected by weather. (B) Since there is little work at high altitudes, safe construction can be performed, and there is no fear of falling or scattering of materials in the vicinity. (C) No temporary equipment such as a tower crane is provided above the building, so that there is no effect on the radio band. However, two of the conventional examples of this type are the all-weather construction methods for building structures, in which an unfinished frame structure is sequentially pushed up from the top floor, and the following problems still remain. ing. (A) The unfinished high-level building work at each level is left as it is, and there is concern about falling or scattering of materials. (B) A facility for transporting materials for building a frame is required for the hierarchical level, and the leveling of the building work cannot be expected. Another conventional example is a method in which a skeleton of one floor is constructed at the ground level and sequentially pushed up. Therefore, the following problems remain, though there is no such problem. (C) Special temporary attachment to the frame is required, such as attaching a dedicated temporary flange for push-up to the pillar. (D) When the frame is pushed up, the frame surrounds the column, so that the beam of the frame cannot be attached to the column before the push-up. Therefore, the beam must be attached at the hollow position.

[0004] It is an object of the present invention to substantially complete the building structure on the top floor near the ground, sequentially lift the completed building structure from the top floor, and build the required number of middle- and high-rise building structures. An object of the present invention is to provide a lifting device capable of performing safe construction without any work and effectively obtaining a building of stable quality.
