Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an assembling and supporting apparatus for upper-story beam reinforcing bars, and more particularly to an assembling and supporting apparatus for upper-story beam reinforcing bars provided with a lifting means.

[0002]

[Prior art]

 Normally, the beam rebars are assembled while being supported by the assembly columns, and they are embedded in the prescribed grooves after the assembly is completed. In the case of the beam reinforcement on the first floor, it can be buried in the underground trench without removing the assembly support from the beam reinforcement after assembly, so an assembly support with a relatively simple structure such as T type or cross type can be used. Can be used. However, in the case of the beam reinforcement on the upper floor, after the beam reinforcement is assembled, the beam reinforcement should be lowered into the groove of the concrete structure while being supported by the assembly support, and then the assembly support should be removed and only the beam reinforcement should be embedded. I have to.

[0003] Conventionally, as an assembly support device for this upper-story beam reinforcing bar, a horizontal bar for supporting the reinforcing bar is fitted on a pair of columns so as to be able to move up and down through a fixture, and stop holes are provided at regular intervals on both columns. I pierced it and attached a pin to the stop hole to fix the fixture for the horizontal rod. The height of the horizontal rod was adjusted according to the spacing of the stop holes by inserting and removing this pin. Therefore, when lowering the beam reinforcement after assembly into the groove, the horizontal rod was lowered while pulling out or inserting the pin at each stage of the stop holes of the pair of columns. Since large beam rebars are supported at dozens of places depending on the assembly support device, it took a lot of labor to carry out the stepwise beam rebar removal work by inserting and removing pins. Also, since the horizontal rod is integrally fitted to the column via the fixture, the horizontal rod can be removed together with the fixture to remove the horizontal rod from the beam rod after lowering the beam rebar to the specified position. There was no choice but to pull the rod out from the upper or lower ends of the stanchions, making this work extremely difficult while supporting heavy beam rebar.

[0004]

[Problems to be solved by the device]

 The present invention solves the above-mentioned problems, and the horizontal rod supporting the beam reinforcing bar can be continuously and smoothly lowered by the handle operation, and the upper-story beam reinforcing bar that can be easily removed from the beam reinforcing bar is provided. It is an object to provide an assembly support device.

[0005]

[Means for Solving the Problems]

 In the assembly support device for the upper beam reinforcement according to the present invention, which achieves the above-mentioned object, a sprocket is provided at the upper part of each of a pair of mounts, a guide roller with a stopper is provided at the lower part, and a chain is stretched between the sprocket and the guide rollers. , Fix the holding tool that is vertically movable on the guide rail at any position between the chain sprocket and the guide roller, engage the worm gear with the handle with the worm wheel gear that is coaxial with the sprocket, and then hold the holder. The feature is that a horizontal rod for supporting the reinforcing bars is detachably placed and passed between them, and the reinforcing rod is supported by the horizontal rod.

[0006]

[Action]

 In the device for supporting and assembling rebars of the upper floor of the present invention, a holder is fixed to a chain stretched up and down by a gear in a frame, and a horizontal rod supporting the beam rebars is detachably mounted on the holder. By placing them, it is possible to unload the beam rebar continuously and smoothly by operating the handle. It is also extremely easy to remove the assembly support device from the beam reinforcement after it is unloaded, simply by pulling out the horizontal rod from the holder.

[0007]

【Example】

 In FIGS. 1 and 2, a sprocket 2 is provided on the upper part of the frame 1, and a guide roll 3 with a stopper is provided on the lower part. A chain 4 is stretched between the sprocket 2 and the guide roll 3. A holder 6 fitted on a guide rail 5 is fixed to the chain 4. On the other hand, the sprocket 2 is supported coaxially with the worm wheel gear 7, and the worm wheel gear 7 is supported by a rhombic bearing (not shown). The worm gear 8 with the handle 10 is supported by a pair of pillow bearings 9 so as to mesh with the worm wheel gear 7. In the present invention, the horizontal bridging rod 11 is passed between the holders 6 of the pair of pedestals 1 configured as described above, and the reinforcing bar 12 is supported by the horizontal bridging rod 11.

The beam reinforcing bar assembling support device according to the present invention constructed as described above is used as follows. First, a pair of pedestals 1 are installed on both sides of the reinforcing bar 12, and a horizontal bridging rod 11 is passed between the holders 6 to support the reinforcing bar 12. Next, the handle 10 is operated to drive the chain 4 via the worm gear 8, the worm wheel gear 7, and the sprocket 2, and the holder 6 fixed to the chain 4 is lifted to a desired height along the guide rail 5. . At the raised position, fix the chain 4 with the stopper of the guide roll 3 and assemble the beam reinforcement. After the beam rebar is assembled, the stopper is released and the handle 10 is reversely operated to gradually lower the horizontal rod 11 into the predetermined groove 13 of concrete. When the beam rebar is lowered to a predetermined position, the horizontal bridge rod 11 is pulled out from the holder 6, and the assembly supporting device is removed from the beam rebar.

[0009]

【effect】

 In summary, the assembly support device for the upper beam reinforcement according to the present invention has the following advantages. (1). The height of the beam reinforcement can be adjusted continuously and smoothly by operating the handle via the chain. (2). Since only the horizontal rod is placed, it is easy to remove the used assembly support device from the beam rebar.
