Description

Technical Field

[0001] The utility model relates to the technical field of concrete reinforcement, in particular to a screw plug with a rubber sleeve for a clear water concrete reinforcement system. Background Art

[0002] As the development of plain concrete in my country is getting better and better, the quality requirements for plain concrete are also getting higher and higher. Plain concrete also represents high-standard and high-precision construction quality in China's cast-in-place concrete industry. The basic screw holes for plain concrete are mainly through-thread screw holes, three-joint screw holes, and five-joint screw holes.

[0003] Based on the existing technology, it is found that:

[0004] The existing five-stage tie screws for exposed concrete only have a single conical plastic plug as the screw hole. During repeated use, the plug mold is deformed due to the force generated by concrete pouring and screw tightening, and cannot fit tightly with the exposed formwork surface, resulting in panda eyes, sand eyes, and blind eyes after the exposed concrete formwork is removed. During the formwork installation process, the screw tightening torque is too large, causing the conical screw hole mold to sink into the exposed formwork surface, resulting in a prominent eye phenomenon with a circle of edges in the screw hole that clearly protrudes from the wall after the exposed concrete wall is formed. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a screw plug with a rubber sleeve for a plain concrete reinforcement system. On the basis of the existing screw hole plug mold, a hard rubber sleeve ring is added, which can fit closely to the template, thereby increasing the contact area between the screw plug and the template, reducing the pressure increased after the screw is tightened, and will not damage the template.

[0006] The technical solution to achieve the purpose of the utility model is: a screw plug with a rubber sleeve for a clear water concrete reinforcement system, including a plastic plug, the inner wall of the plastic plug is fixedly connected with a bolt, one end of the bolt is provided with a threaded groove, a screw is threaded in the threaded groove, the other end of the plastic plug is sleeved with a rubber sleeve, the side of the rubber sleeve away from the plastic plug is fitted with a clear water formwork, one side of the clear water formwork is provided with a mounting hole, one end of the bolt passes through the mounting hole and extends to one side of the clear water formwork.

[0007] In some embodiments, the plastic plug is shaped like a frustum.

[0008] In some embodiments, the rubber sleeve is in the shape of a "ring".

[0009] Compared with the prior art, the present invention has the following significant advantages:

[0010] The utility model adds a hard rubber sleeve ring to the existing screw hole plugging mold, which increases the contact area between the screw plug and the template, and can closely fit the template, while reducing the pressure added after the screw is tightened, and will not damage the template. In addition, the hard rubber has good durability and waterproof properties, and the strength is increased when it is put on the plastic plug. It does not deform after multiple turnovers, so that the screw hole forming effect is good after the concrete is poured.

[0011] The invention solves the existing problem that the plug mold is deformed due to the force generated by concrete pouring and screw tightening, and cannot be closely fitted with the surface of the exposed concrete template, resulting in panda eyes, trachoma and blindness after the exposed concrete template is removed. BRIEF DESCRIPTION OF THE DRAWINGS
