In the drawings of the present invention, the reference numeral 5a is a fastening hole for connection installation using the upper end and the bolt of the copper bar.

On the other hand, the present invention may be variously modified and may take various forms in applying the above configuration.

And it is to be understood that the invention is not limited to the specific forms referred to in the above description, but rather includes all modifications, equivalents and substitutions within the spirit and scope of the invention as defined by the appended claims. It should be understood that.

Referring to the operation and effect of the drop-down support device for preventing the fall of the flow path to the bottom surface of the present invention configured as described above are as follows.

First, the drop-down support device 1 applied to the present invention prevents the Eurofoam from falling directly to the floor when disassembling the Eurofoam (form) 8, and the Eurofoam does not fall to the floor so that a large impact sound is not generated. In addition, since the impact sound is not generated as described above, it is intended to improve workability and work efficiency.

Referring to the effects of the present invention in more detail as follows.

That is, as shown in Figure 4 to sequentially assemble the disassembled parts as shown in Figure 5, wherein the movable pipe 3 is fitted to the outer peripheral surface of the fixed pipe 2, the pedestal 4 is fixed pipe (2) It is fitted to the top and fixed.

The drop-down support device 1 assembled as shown in FIG. 5 is installed on the upper end of the support bar not shown in the drawing, in which bolts are fastened to a plurality of fastening holes 5a formed in the connection plate 5. The drop down support device 1 is fixedly installed together on the upper end of the base.

Then, the present invention is to raise the movable pipe (3) in the intermediate position by raising the engaging piece operating means (7) as shown in Figure 8 in a lowered state as shown in Figure 8, wherein the operator opens the movable pipe (3) In the state of being positioned higher than the position of (2a), the lever operating step 6 is operated so that the locking jaw (7-8) (7-8a) is caught by the lower end of the movable pipe (3) as a result. The movable pipe 3 is caught in the intermediate position of (2).

In more detail, when the lever 6a is rotated in the clockwise direction, the rotating shaft 6d provided between the connecting piece 6b connected thereto and the rotating catch pieces 6c and the rotating catch piece 6c connected to each other rotates. In addition, the operation cam 6e built on the rotation shaft 6d rotates together.

In addition, when the operation cam (6e) is rotated as shown in Figure 8 to Figure 7 in the operation (7-1) is raised to the upper, at this time the operation cam (6e) is rotated in the clockwise direction The inner surface of (7-4) is pushed and moved to eventually raise the operating period 7-1 as shown in FIG. Of course, when the actuating cam 6e rotates counterclockwise, a space is formed between the actuating cam 6e and the actuating hole 7-4, and the actuating portion 7-1 is formed by its own weight as much as this space. As a result, the operation 7-1 is automatically moved up and down.

When the operation section 7-1 is raised, a pair of locking pieces 7-6 and 7-6a, which are narrowed to each other, are opened, which is an inclined surface formed at the top of the operation section 7-1 ( 7-3) ascending the support (7-7) (7-7a) to raise the mutually narrowed locking pieces (7-6) (7-6a) and at the same time the operation (7-1) Ascending to the uppermost end of the support (7-7) (7-7a) is caught on both ends of the operation period (7-1), the locking pieces (7-6) (7-6a) is no longer narrowed.

And between the operation (7-1) is to move up and down around the hinge shaft (7-5) by the long hole (7-2) formed on the top, the pair of engaging pieces (7-6) (7-6a) is rotated about the hinge axis (7-5).

On the other hand, when the locking pieces 7-6 and 7-6a are opened, the lower locking jaws 7-8 and 7-8a protrude outward of the opening 2a and hold in such a state. When the movable pipe 3 is released, the movable pipe is lowered by its own weight and then caught by the locking jaws 7-8 and 7-8a.

In the present invention, the movable pipe (3) is not lowered by the catching jaw (7-8) (7-8a), but in any case is provided with a safety device to prevent the movable pipe (3) from descending for any reason. will be.

That is, in the state where the lever 6a is rotated in the clockwise direction as described above, the safety pin 2d is inserted into the hole 2c of the support jaw 2b. Then, even if any cause (eg, severe vibration or damage to the component) occurs, the lever 6a is prevented from rotating because the safety pin 2d blocks the connecting piece 6b as shown in FIG. 9.

In the state described above, the operator puts the Euroform (form) 8 on the reinforcing table 8 and the upper end of the support piece 3a, and then casts the slab on the upper part of the pedestal 4 to cure.

After the curing process of the slab is finished, the reinforcing rod (8) and the euroform (form) should be removed again. In this case, the lowering of the reinforcing rod (8) and the euroform by using the locking piece operating means (7) is lowered by about 10-20 cm. Because of the separation, it is released without impact noise.

That is, after removing the safety pin 2d from the hole 2c again, the lever 6a is rotated counterclockwise. Then, the lever operating means 6 and the engaging piece operating means 7 are operated in the reverse order of the above-described operation. At this time, when the operation 7-1 is lowered, both sides of the operation 7-1 are supported. There was no place for the support (7-7) (7-7a) that was there. In this state, the locking pieces 7-6 and 7-6a are narrowed and the locking pieces 7-8 and 7-8a are moved to the inside of the opening 2a by the weight of the movable pipe 3 itself. As a result, the movable pipe 3 is lowered so that there is no supporting device and falls to the upper end of the support jaw 2b.

The movable pipe 3 is lowered like the reinforcing rod 8 and the euro foam, and lowered by about 10 to 20 cm so that the impact noise is not much, and there is no complaint from the surrounding area. The efficiency can be improved.

As described above, in the state in which the reinforcing bar 8 and the flow path are lowered by about 10 to 20 cm, the operator can detach the flow path from the reinforcing bar 8 first.

On the other hand, the present invention can be implemented by differently configuring the movable pipe (3-1) provided in the drop-down support device as shown in Figure 10, 11, 12.

That is, the support piece 3a-1 protruding from the outside of the movable pipe 3-1 is formed to be inclined rather than the above-described step, which is when the reinforcing bar 8 is installed. The gap does not occur between the reinforcing bar 8 can be installed without shaking.

In addition, since the support piece 3a-1 is formed to be inclined by about 45 degrees even in the process of attaching and detaching the reinforcement stand 8 to the support piece 3a-1, the support piece 8 is more conveniently installed on the support piece 3a-1. It becomes possible.

As described in detail above, the present invention is to provide a drop down support device provided with a lever operating means and a locking piece operating means.

In another aspect, the present invention is to prevent the euro foam falling directly to the bottom surface when disassembling the euro foam.

In addition, the present invention is to prevent the euro-foam from falling to the floor so that a large impact sound does not occur.

In addition, the present invention is intended to improve the workability and work efficiency because the impact sound is not generated as described above.

The present invention is also the effect of reducing the impact noise can be eliminated complaints in the surrounding area.

In addition, the present invention allows the drop-down support device to firmly support the slab, the euroform and the reinforcing bar, and at the same time, the drop-down support device can be easily detached from the club during disassembly.

The present invention is a very useful invention that can significantly improve the quality and reliability of the product due to the above-described effect so that consumers can plant a good image.
