DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column reinforcement structure for streamlining assembling and disassembling work of a plurality of connecting beams and brace members arranged between columns of a temporary beam assembly apparatus for building construction.

[0002]

2. Description of the Related Art A temporary beam assembly device has been proposed as a temporary scaffold for building a high-rise building. This temporary beam assembling device includes at least four temporary struts arranged around a building to be constructed, and a temporary beam assembling structure disposed above each temporary strut via an elevating device.

[0003] The temporary beam structure is provided with a construction facility for building a building such as a crane, and a temporary roof is hanged over the building. The beam is provided via a lifting device according to the progress of the building. By raising the assembled structure and repeating the work of adding the unitized columns at the ascending position in a scale-like insect-like manner, it is sequentially raised.

Further, after the completion of the construction, by removing the columns while lowering the beam structure, the columns can be finally removed together with the temporary columns, so that the construction of the temporary structures for the building can be automated, and a similar size can be obtained. Since it can be diverted to building construction many times, and because of the roof, construction can be performed without being affected by the weather, there are advantages such as a stable construction period.

[0005]

However, in order to prevent the temporary support from swinging and secure the self-sustaining stability, it is necessary to provide a reinforcing stay. For this reason, in the past, since the copy was taken from the building under construction, the connection work was troublesome and required complicated manual work by workers, and when dismantling, it was called so-called useless construction after removing the copy. Repair work was required, and there were problems with the finished appearance.

On the other hand, by arranging a connecting beam and a brace material as a reinforcing structure between the columns, the self-standing stability of the columns can be increased, and the rigidity of the entire structure can be improved. However, in this case, the construction and removal work becomes more complicated than taking a copy in the building, and in particular, the work of carrying in and out the material every time of assembly and removal is troublesome.

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to always carry out construction and dismantling work of a connecting beam and a brace material at a fixed position every time the column is extended or lowered, and to carry out the material. An object of the present invention is to provide a reinforcing structure for a pillar in a temporary beam assembly device for a building, which does not require an entry work.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a plurality of pillars arranged around a building to be constructed, and a pillar provided at the top of each pillar to sequentially add the pillars upward. In a temporary beam assembly device having an elevating device that holds a beam assembly structure at the upper part, in a stacked state via a holding device at a lower portion of the beam assembly structure, and sequentially from a lower portion at a predetermined interval every time a column is extended. A plurality of tethers erected between the columns, at least one pair of brace members connected to the tethers so as to be foldable and expandable, and having their deployed ends connected to the tether immediately above in a triangular shape; A lifting device disposed at a lower portion of the set and detachably connected to a deployed end of the brace material.

[0009]

When the column is extended, the plurality of connecting beams stocked in a stacked state simultaneously rise. If both ends of the lower connecting beam are fixed to the column, and the brace material is raised using the pulling device in a state where the brace material is cut off from the holding device, the brace material is developed in a triangular shape with the extension of the column. When the developed ends are connected in this state, the assembly of the brace material having the developed end as the top is completed. Further, when the column is extended and the connecting beam directly above coincides with the top of the brace material, if this top is connected to the connecting beam directly above, the brace material is erected between the upper and lower connecting beams. Next, by performing the same operation on both ends of the connecting beam directly above, the connecting beam and the brace material are sequentially installed at a predetermined interval every time the column is extended.

[0010] At the time of dismantling, by repeating the operation opposite to the above, each connecting beam descends to the ground together with the pillar while being stocked in the holding device sequentially from the top.

[0011]
