Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a beam suspension device.

(Conventional technology) Conventionally, in the process of constructing a so-called SRC building, for example, there is a reinforcing beam on the floor directly above the underground beam, but when assembling the beam of the underground beam without a steel frame, steel scaffolding or The upper end reinforcement of the beam was supported using a stand or the like, for example, on a receiving metal fitting passed between reinforcing steel scaffolds, or the upper end reinforcement was held on stands installed on both sides, and then the beam reinforcement was assembled.

(Problem to be solved by the invention) However, according to this method, the upper end reinforcement is simply placed on the bracket or the top of the stand, so the range of level adjustment of the beam reinforcement is narrow, and the height of the scaffolding board or stand is also limited. It was difficult to accurately produce the beams, so there was a limit to increasing the accuracy of beam construction.

An object of the present invention is to provide a beam suspension device that can widen the range of beam level adjustment and improve beam construction accuracy.

(Means for Solving the Problems) The present invention is characterized in that at least one of both ends of the suspension support is provided with a threaded portion, and the threaded portion of the one end is provided with a hook or One of the reinforcing bar receivers located in a direction orthogonal to the suspension support is screwed together, and the other is rotatably supported at the other end of the suspension support.

Then, the suspension support is hung vertically by hooks to the beam steel frame that has already been erected directly above the beam, and the beam reinforcement is supported by the reinforcing bar receiver at the bottom. The length is adjusted by expanding and contracting with the expansion and contraction adjustment section, and the height of the reinforcing bar receiving section is finely adjusted by rotating the suspension support, thereby adjusting the level of the beam reinforcement.

(Example) An example of the present invention will be described below based on the drawings.

A hanging rod 1 serving as a hanging support is formed by fitting and connecting two upper and lower pipes 2 and 3 of different diameters, and is vertically expandable and retractable. In the connecting part of both pipes 2 and 3, height adjustment pin holes 4, ... are provided at regular intervals in the axial direction, and a fixing pin 5 can be inserted into these pin holes, and with this pin, both pipes are connected. The connection is fixed. The height adjustment pin hole 4 and the fixing pin 5 are
It constitutes an expansion/contraction adjustment section for the hanging rod 1. Threaded portions (only the upper threaded portion 2a is shown) are provided at both upper and lower ends of the hanging rod 1, that is, at the upper end of the upper pipe 2 and the lower end of the lower pipe 3. A support cylinder 6a that supports the hook 6 is screwed to the upper threaded portion 2a. This hook is attached to the support cylinder 6a with the shaft 7 as the center of rotation,
A coil spring 8 is hung between the hooks at the lower part thereof to apply a spring force in the direction of closing the hooks. The upper end of the hook 6 can be hooked to the lower flange of the beam steel frame 9 on the upper floor.

Further, the lower threaded portion is composed of a female thread formed in the lower end opening of the lower pipe 3, and the threaded base portion 10a of the T-shaped reinforcing bar receiving portion 10 is threadedly connected to this threaded portion, and the thread direction is the same as that of the threaded portion 2a. is the opposite. Two hanging bars 11, 11 hang down from this reinforcing bar receiving portion, and the hairpin bars 12 are supported in the horizontal direction at the lower ends of these hanging bars.

Next, how to use it will be explained.

First, adjust the length by vertically expanding and contracting the hanging rod 1 according to the height from the underground beam to be constructed to the beam steel frame 9 directly above, and then insert the fixing pin 5 into the specified adjustment hole 4.
to fix the connecting parts of both the upper and lower pipes 2 and 3. Then, the hanging rod body 1 is positioned below the beam steel frame 9, the hook 6 is opened and hooked to the lower flange of the beam steel frame 9, and the hanging rod body is suspended from the beam steel frame. Thereafter, the hairpins 12 are supported on the reinforcing bar receiving portion 10 via the suspension bars 11. And kanzashi muscle 1
2 supports both ends of the upper end reinforcements 13, ... of the beam, the stirrup 14 is held by the upper end reinforcements, a lower end reinforcement (not shown) is passed under the stirrup, and a connector is placed on the reinforcing bar receiver 10. Receptacle bar 15,
15, and the shear connector reinforcement 16 is wrapped around this connector support reinforcement, completing the assembly of the underground beam reinforcement. If you need to adjust the level of the beam, for example to lower the level a little, hold the fixing pin 5 and turn it counterclockwise around the hanging rod 1, and the hanging rod will rotate in the direction of the arrow. Therefore, the reinforcing bar receiver 10 gradually descends from the lower pipe 3, and stops rotating when it reaches a desired level.

After that, concrete will be poured and 17 underground beams will be removed. Note that after concrete is poured, the suspension rod 1 is removed from the beam steel frame 9;
1 and hairpins 12 are filled in.

The upper end reinforcement 13 of the beam may be supported by the reinforcement receiving part 10. Further, the threaded portion may be provided on at least one end of the hanging rod 1, and in this case, the other end may be provided with a hook 6.
Alternatively, it is necessary to connect the reinforcing bar receiver 10 rotatably. Further, the hanging support may be formed of a long plate. Beam reinforcements are not limited to those related to underground beams.

(Effects of the invention) As explained above, according to the invention, the suspension support can be expanded and contracted by the expansion/contraction adjustment section, so the level adjustment range of the beam reinforcement can be widened, and the screw section is provided. Because of this, fine adjustments can be made freely, and since the beam steel frame is used as the suspension rod, the level of the reinforcing bar receiving portions is accurate, which improves the accuracy of beam construction.
