Description

[Detailed description of the invention] This invention relates to the provision of a column reinforcement reinforcement for pressure welding.

Normally, long column reinforcement welding is done by placing concrete on a floor that has developed strength, then using bidays as a stable base and setting up scaffolding, on which workers can add column reinforcements for the upper floors. This will be carried out in support of the

In addition to pressure welding workers, workers are needed to hold the column reinforcements, and it is essential to install scaffolding for these workers, but this must be installed on a stable foundation. Therefore, slab formwork, etc. that has not yet been poured with concrete is unsuitable as a foundation.

Therefore, even if you want to press the column reinforcements on the upper floor before pouring concrete on the lower floor in a work place where the construction period is short, or you want to press two floors together at one place, the scaffold installation itself will not be as stable as mentioned above. This is not possible due to circumstances such as the absence of a foundation or the presence of slab formwork, which makes it impossible to install through.

This proposal was created in view of the above circumstances, and eliminates the need for scaffolding and workers to hold the column reinforcements, and
To provide an additive for press-welding column reinforcements that enables pressure-welding of column reinforcements on the upper floor before pouring concrete on the lower floor and also enables pressure-welding of two floors at one location.

Details of this will be explained below based on embodiment figures.

Figure 1 shows the whole of the proposed product as it is used. In the figure, 1, ... are the rising parts of the column reinforcements on the lower floor, 2 are the column reinforcements 3 attached to the column reinforcements 1 on the other side, and the column reinforcements 3 on the upper floor. 4 and 5 indicate the column and floor sections for concrete pouring, respectively.

Reference numeral 6 refers to the column reinforcing metal fittings for pressure welding of the present invention, in which the following metal fittings are attached to each of the upper end a, the lower end b, and the intermediate predetermined part c of a long rod-shaped body such as a conduit, for example. It is something that has been done.

That is, first, to the upper end a, as shown in FIG. 2, a metal fitting 8, which is formed by expanding both arms of a U-shaped rod-like body into a wider shape from the middle, is welded, and to the lower end b, as shown in FIG. As shown in the figure, a metal fitting 9 formed by bending downward from the middle of both arms of a U-shaped rod-shaped body is welded.
Further, in the intermediate predetermined portion c, as shown in FIG.
A metal fitting 14 having 2 and 13 attached thereto is clamped.

Of these, the hardware 14 plays the main role in supporting the column reinforcement 1 on the lower floor, and is clamped to the rod-shaped body 7 by the tightening bolts and nuts 10, while the other The attachment bolt/nut 11 serves as a stopper for inserting the column reinforcement 1, and the upper and lower bolts 12 and 13 serve to secure the column reinforcement 1 and prevent it from being disengaged.

Note that the reason why nuts are not attached to the upper and lower bolts 12 and 13 is to simplify and speed up the work of unfitting them from the columnar reinforcing bars. Even if there is no screw, the tightening will not loosen.

Moreover, the reason why the rod-shaped body 7 is integrated with the removable tightening bolt 10 without welding is because the metal fitting 14 is different from the other metal fittings 8 and 9 in that it is a column bar 1 with a different height. This corresponds to the circumstances in which it must be assembled.

The hardware 9 is tightly fitted with the column reinforcement 1, and is set by placing its lower end on the floor 5 of concrete pouring or on the hoop reinforcement before pouring, and can be attached and detached with one touch.

The rod-shaped body 7 is assembled to the column reinforcement 1 at two points, the metal fittings 14 and 9.

The wide arm part of the hardware 8 is used to guide the fitting of the column reinforcement 3 on the upper floor, and this allows the worker to hold the lower part of the column reinforcement 3 above the floor 5 with respect to the hardware 8 located above. The column reinforcement 3 can be easily fitted.

As a result, the upper part of the column reinforcement 3 is supported by the hardware 8, so the lower part is already supported by the column reinforcement 1.
If it is assembled into the pressure welding device 2 attached to the upper end, it will be supported and stabilized at the upper and lower parts, and the same operator can immediately carry out the pressure welding.

As described above, according to the present proposal, there is no need for scaffolding or workers to support column reinforcements, and it can also be carried out on formwork without requiring the existence of a stable foundation for concrete pouring. This also makes it possible to press the column reinforcements on the upper floor before pouring concrete on the lower floor in a workshop with a short construction period, or to press two floors together at one location.
