Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a column reinforcement anti-pollution protection device. Background Art

[0002] During the construction of reinforced concrete structures, protecting the column reinforcement from concrete pollution can effectively ensure the quality of concrete construction and the safety of personnel. During the construction process, workers often step on the reinforcement directly for the convenience of work. This behavior not only applies forces in different directions to the column reinforcement, causing the anchor position of the column reinforcement to loosen, resulting in damage to the load-bearing structure, but also easily brings danger to the workers. Therefore, it is extremely important to do a good job of protecting the column reinforcement during the construction process.

[0003] At present, in the process of pouring concrete, in order to prevent the column steel bars from being contaminated by concrete, most of the methods are to wrap the column steel bars with plastic film or wrap colored cloth strips around the column steel bars for protection. This protection method is not strong enough and is easy to cause environmental pollution after removal. With the advancement of science and technology, some people have proposed to use PVC sleeves to protect the column steel bars from pollution and have developed new column steel bar anti-pollution protection devices. However, during the construction process, this protection device is inefficient and the sealing protection is insufficient. Concrete will still flow through the gap between the PVC pipe and the steel bar, causing the column steel bar to be contaminated and the column steel bar to stick to the sleeve, which is not conducive to removal and recycling.

[0004] The present application now proposes a column reinforcement anti-pollution protection device to solve the above-mentioned problem. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a column steel bar anti-pollution protection device. The device is easy to operate, has strong sealing performance, can effectively prevent cement slurry from entering the casing to contaminate the steel bars, and greatly improves work efficiency. It is also easy to disassemble and can be reused, which is more economical and practical.

[0006] The technical solution to achieve the purpose of the utility model is: a column steel bar anti-pollution protection device, including a PVC sleeve, one side of the PVC sleeve is open, a closing plate is arranged on the outside of the PVC sleeve, two sockets are penetrated through the top opening of the PVC sleeve, two plug plates matched with the sockets are arranged on the closing plate, a closing piece is arranged on the closing plate, and the closing piece is connected to the plug plate.

[0007] In some embodiments, the tightening member includes two groups of fixed blocks fixedly connected to the outer surface of the tightening plate, wherein the inner wall of one group of the fixed blocks is fixedly connected to a light rod, wherein the inner wall of the other group of the fixed blocks is rotatably connected to a bidirectional threaded screw, and wherein the outer side of the other group of the fixed blocks is provided with a rotating knob, and the rotating knob is coaxially fixed with the bidirectional threaded screw.

[0008] In some embodiments, the outer sides of the two plug plates are fixedly connected with connecting plates, the connecting plates are slidably connected to the surface of the polished rod, and the connecting plates are threadedly connected to the bidirectional threaded lead screw.

[0009] In some embodiments, the PVC sleeve and the inner side of the plug board are both provided with flexible filling materials.

[0010] Compared with the prior art, the utility model has the following significant advantages:

[0011] First, the utility model reduces the weight of the material by providing the socket on the PVC sleeve and the matching plug plate, making it easy to carry and operate. When in use, the steel bar can be protected by only inserting the plug plate, which greatly improves the operating efficiency.

[0012] Second: The utility model, through the setting of the tightening member, can further reduce the distance between the connecting plates, i.e. the plugging plates, by turning the rotating knob when in use, and can further reduce the gap between the PVC sleeve and the steel bar, and further improve the sealing performance of the device by filling with flexible materials, and further improve the protection effect on the steel bar;

[0013] The invention solves the problems of the existing steel bar protection technology, that is, the protection sealing is not strong, the protection effect is not good and it is not convenient to disassemble and reuse. BRIEF DESCRIPTION OF THE DRAWINGS
