Description

[Detailed explanation of the invention] Industrial field of application This invention is designed to provide
For example, the present invention relates to a bundling used for constructing a safety passage as shown in FIG. 2 or a stage for work or material storage as shown in FIG. More specifically, support is provided by raising and supporting the Bata square timbers, etc. on which the H-beams (large pullers), etc. of the passageway or stage are placed, to a height that does not interfere with the assembly of the beam reinforcing bars or disturb the beam reinforcing bars. This invention relates to a universal bundling system that has a wide range of uses and is flexible for the size of steel frames.

Conventional technology Conventionally, after the steel frame of a building has been erected, safety walkways and work stages have been constructed on the steel beams of each floor in order to safely and efficiently carry out the final tightening of the steel frame, welding, assembling reinforcing bars, and other operations. It is commonly done.

These safety passages and stages are constructed using bundles so as not to hinder the assembly of beam reinforcing bars attached to the steel beams or to disturb the carefully assembled beam reinforcing bars. In other words, single pipes and H-beams (large hiki) for safety passages, etc., are placed on top of square timbers, etc., which are held up to a certain height and supported by bundling.

Conventionally, for bundling, concrete blocks of appropriate size and height are used, which are placed on the flanges of reinforcing beams and tied with numbered wires, etc., and fixed, and square baton materials, etc., are placed on top of the concrete blocks. They were placing it on the ground and assembling a safe road and stage.

Alternatively, small pieces of angles or H-beams such as C-beams and H-beams are welded onto steel beams and used as bundles.

Problems that the present invention aims to solve: When concrete blocks are used as bundles as in the past, it is time-consuming to tie and secure the concrete blocks onto the reinforcing beams, and the work requires skill. It takes. In addition, there was a problem in that the square wood placed on the concrete blocks lacked positioning and security, and was visually dangerous.

In addition, safety passageways, stages, etc. are dismantled and removed after the slab formwork is assembled and before concrete is poured, but when dismantling it, it takes time to untie the ties that have been tied together, and if the ties are cut, they become consumable materials. There was a problem that wire waste was generated.

Next, angles and C-beams welded onto steel beams,
When using small pieces such as H-beams as bundles, welding heat, etc. will be applied to the steel beams on site, which is strictly avoided in terms of design management. However, welding small pieces in advance at a factory poses various problems and is not practical. Moreover, when dismantling after use, the bundle of small pieces must be cut and removed.
Therefore, there were problems in that it was time-consuming and could not be used for other purposes.

Means for Solving the Problems As a means for solving the problems of the above-mentioned prior art, the universal bundling according to this invention is
As shown in the embodiment in Figures 1 to 3, a core bolt 3 of a predetermined height is stood upright on a pedestal 2 whose width is narrower than the flange width of the steel frame 10, and a handle 4 is attached to the core bolt 3 for attachment and detachment operation. nut 5 is screwed in. A slip ring 14 that is prevented from moving downward is rotatably provided on the outer periphery of the nut 5 for attachment and detachment, and a flange holder 6 that is attached to the flange 10a of the reinforcing bar 10 is attached to the slip ring 14.
