Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reinforcing assembly method for underground beams in steel reinforced concrete (SRC) buildings.

Conventionally, for this type of underground beam reinforcement assembly, special reinforcing steel scaffolding was constructed and reinforcement work was carried out, which required a lot of man-hours and materials, and the construction period was long. It was hot. Another method used was to place and support underground beams on underground beam brackets, but this also required a lot of man-hours and also had problems with construction accuracy, such as eliminating the fogging of the bottom reinforcing bars. There was a problem.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a novel underground beam that can significantly reduce the number of man-hours and construction materials, shorten the construction period, and improve construction accuracy. To provide a reinforcement assembly method.

First, embodiments of the method of the present invention will be explained based on the drawings.

In the figure, 1 is a pre-built SRC structure 2
This beam material 1, which is a floor beam material, is composed of a beam steel frame 2, upper end main reinforcements 3..., lower end main reinforcements 4..., and stirrups 5. 6 is a hanging metal fitting made of round steel, and a turnbuckle 7 is provided in the middle of the hanging metal fitting.
It is constructed such that its length can be adjusted, and hooks 8 and 9 are integrally formed at both ends thereof, respectively. 10 is an underground beam, and the upper main reinforcement 11
. . . , lower end main reinforcing bars 12 . . . , and stirrups 13 .

Next, the procedure for assembling reinforcement for the underground beam 10 will be explained. First, one hook 8 of the hanging fitting 6 will be
to an appropriate location on the second floor beam 1 and attach it to the hanging bracket 6.
hang down. In the illustrated embodiment, an example is shown where it is hooked to the lower end main reinforcements 4 of the second floor beam material 1, but it can also be hooked to the upper end main reinforcements 3... or the beam steel frame 2. Then, the main reinforcing metal fitting 14 is hooked onto the other hook 9 of the hanging metal fitting 6, and fixed with a wire or the like as necessary. In this case, as shown in the figure, a pair of left and right hanging fittings 6 may be hung, and the main reinforcement bracket 14 may be hung between the left and right pair of hooks 9, or only one hanging fitting 6 may be hung, and the hooks The main reinforcement bracket 14 may be hooked onto the 9. In this way, the upper end main reinforcements 11 for configuring the tension direction underground beam 10 are placed and supported on the main reinforcement support fittings 14 positioned almost horizontally, and the stirrups 13 are further mounted on the upper end main reinforcements 11. Hang ... on the inside of the bottom of stirrup 13... and lower end main reinforcement 1.
2... is placed. And these upper and lower end main reinforcements 1
1..., 12... and the stirrup 13 are bound and fixed to each other, and the reinforcement assembly of the underground beam 10 is completed. At that time, by adjusting the length of the hanging fitting 6 using the turnbuckle 7, the level is adjusted so that the reinforcement of the underground beam 10 is horizontal. after that,
Prior to pouring concrete, the hanging fittings 6 and main reinforcing fittings 14 are removed and reused in another construction project.

As is clear from the above explanation, the method for assembling reinforcement for underground beams according to the present invention involves hooking one hook of a hanging fitting having hooks at both ends to an appropriate location on a pre-constructed second floor beam. The upper end main reinforcement of the underground beam is placed and supported on the main reinforcement holder which is suspended from the other hook so as to be almost horizontal. Since it also supports the underground beams, it makes effective use of the existing beam materials on the second floor and makes it easy to assemble the reinforcing beams for underground beams without the need for special reinforcing scaffolding. can be done. Moreover, the hanging metal fittings are equipped with turnbuckles,
Since the length is adjustable, the construction accuracy of reinforcement can be improved.
In the end, we were able to reduce costs by significantly reducing the number of man-hours and materials used, shorten the construction period, and improve construction accuracy.
