BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of an all-weather construction method and a lifting device for building structures such as buildings and condominiums.

[0002]

2. Description of the Related Art Conventionally, as a foundation construction method for an all-weather building structure, as disclosed in JP-A-3-103737 or JP-A-3-107038, a core 1 is provided with a temporary support. , And a jack 12 is installed at the place where the pillar 13 of the building 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 a bottom formwork for columns and a formwork for columns are provided. The concrete of the pillar 13 and the slab 24 is cast. At the stage when the pillar 13 is lowered to a state where the pillar 13 can be self-supported, the jack 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. or,
As another construction method, as shown in Japanese Patent Application Laid-Open No. Hei 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. S is placed on the floor of each floor.
In such a construction method of the building frame, the step of raising the floor slab S is sequentially performed from the floor slab S on the top floor to the floor slab 1S on the next floor. A construction method of raising the floor slab S while supporting the floor slab S by a lifting device 2 arranged on the lower surface of the floor slab S is known. Also,
As another construction method, as shown in Japanese Patent Publication No. 7-33689, one frame of the skeleton is intensively constructed at the ground level, and after completing the framing of the first floor, the pillar of the skeleton is pushed upward by the height of the floor. A building having a push-up pin hole and a flange having a fixing pin hole attached to a pillar, and a center having a pin engageable with the push-up pin hole. There is a known construction method in which a hole jack and a skeleton holding device having a pin that can be engaged with the fixing pin hole are arranged around the pillar, and the pillar of the skeleton is pushed up with this.

The following characteristics are recognized in the above-mentioned conventional construction method for building structures. (A) Work can be performed in all weather conditions and is not affected by weather conditions. (B) Since there is little work at high altitudes, safe construction can be performed, and there is no fear of falling or scattering materials nearby. (C) No temporary equipment such as a tower crane is installed above the building, so there is no effect on radio waves.

[0004] However, two of the conventional examples of this kind are 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. Is left. (A) Unfinished high-level building work at each level is left as it is, and there is concern about falling or scattering of materials. (B) Equipment for transporting building construction materials is required for each stratum, making it impossible to equalize the amount of construction work. Another example of the conventional example is a method in which a frame of one floor is constructed at the ground level and sequentially pushed up, so the following problems are left though the above problems are not present. . (C) It is necessary to provide a special temporary mounting to the frame, such as mounting a dedicated temporary flange for push-up on the pillar. (D) At the time of pushing up the pillar of the skeleton, the frame surrounds the pillar, so that the beam of the skeleton cannot be attached to the pillar before the push-up. Therefore, the beam must be attached in the hollow position.

In order to solve the above technical problems, the present inventors have proposed a construction method for a building structure and a lifting device for a lifting structure of a building structure as disclosed in Japanese Patent Application Laid-Open No. 9-88185. is suggesting. This published prior art is to complete the building structure on the top floor near the ground, lift the completed building structure from the top floor in order, and build the required number of mezzanine and high-rise building structures. It is an object of the present invention to provide a construction method and a lifting device capable of performing safe construction without any trouble and efficiently obtaining a building of stable quality.

An object of the present invention is to solve the above-mentioned problem described in Japanese Patent Laid-Open No. 9-8818.

In this state, the elevating beam 44 is further lowered, and when the upper surface of the beam receiver 47 provided on the lower beam is lowered slightly below the lower surface of the beam connection 32a, the beam receiver 47 is lowered. The beam receiver 47 is moved laterally (rightward on the paper) along the elevating beam 44 to set the beam receiver 47 below the beam connection 32a. (See Fig. 1c)

Next, the screw shaft 37 is driven to make the intermediate main column 32 larger, specifically, slightly higher than the first floor, so that the lower surface of the intermediate main column 32 and the upper surface of the buried column 52 are opened. The lifting beam 44 is stopped when the vehicle is lifted slightly higher than the height of the intermediate main column 32 at the height of the first floor, and a new intermediate main column 32 is inserted into the lower space of the intermediate main column 32 on the upper floor. I do. (See Fig. 1d)

In this state, the elevating beam 44 is lowered, and the lower end of the intermediate main column 32 of the upper floor is supported on the upper end of the newly introduced intermediate main column 32 during the descent, and the load is deposited. Further, the floating end of the lifting beam 44 released from the beam connection 32a by the lowering lifting beam 44 and the knock pin 45 connecting the lifting block 41 are removed, and the free lifting beam 44 is moved outward. Turn about 90 degrees. Since the swiveled elevating beam 44 is located outside the region of the beam connection 32a of the newly-loaded intermediate main column 32, the elevating beam 44 descends to the lowest elevating movement start preparation position. (See Fig. 1e)

Then, the elevating beam 44 is turned back by about 90 degrees in the reverse direction, and its free end is connected to the elevating block 41 by the knock pin 45. (See Fig. 1a)

By repeating the operations shown in FIGS. 1A to 1E using the lifting device D and the lifting device A synchronized with the behavior of the lifting device D, a building of a desired floor can be constructed. Then, after all the lifting devices A and D are disassembled outward and removed, the construction work on the first floor is completed to complete the building structure B on the required level.

[0046]

According to the configuration of the present invention as described above,
The following effects are obtained.

Work can be performed under all weather conditions, the construction period can be shortened without being affected by the weather, and work can be performed safely because there is no work at high altitudes. Since this is a construction method that sequentially completes the corner framing from the top floor to the required floor, all work is done on the ground floor and a stable quality building is obtained.Furthermore, the almost completed building framing is lifted. Since the point of heavy action is provided by the support on both sides of the beam near the outer periphery and the middle main column, it is possible to withstand the load that increases as the story progresses, and to support the beam every time the building frame of each story is completed. Adjustment and zero point adjustment control of all lifting devices are performed.
Of course, it is possible to efficiently build a mid- to high-rise building without damage due to the lifting of the completed building frame.

By lifting the lifting device A and the lifting device D in synchronization with each other, the lifting load shared by each lifting device can be reduced, and the lifting device can be downsized. Since D can be refilled, the height of the lifting device D can be configured to be lower than one level of the building.
