Sealing device for abutted seams of formworks

Abstract

The invention relates to a sealing device, in particular to a sealing device for abutted seams of building formworks. The sealing device comprises a grooved main body. The cross section of the grooved main body is H-shaped, the grooved main body is made of plastics, the groove width of the grooved main body is equal to the thickness of each formwork, the groove depth of the grooved main body ranges from 8mm to 12mm, strip-shaped grooves are formed in the groove side walls and the bottom wall of the grooved main body, rubber sealing strips are arranged in the strip-shaped grooves, rounded corners are arranged at the edges of the outer walls of joints of the grooved main body and the inner sides of the formworks, the radius of each rounded corner is equal to the wall thickness of the corresponding joint, wedge grooves are formed in the middles of the outer walls of joints of the grooved main body and the outer sides of the formworks, and the depth of each wedge groove is larger than a half of the thickness of each formwork. According to the technical scheme, the sealing device for the abutted seams of the formworks has the advantages that the abutted seams of the formworks can be quickly closed by the aid of the sealing device, and accordingly leakage can be prevented.

Description

technical field [0001] The invention relates to a sealing device, in particular to a sealing device for building formwork joints. Background technique [0002] The vast majority of existing high-rise building structures use reinforced concrete frame structures, so a large number of formwork must be used in the building construction process. Due to the limited length of the formwork, it is very common to splice and use multiple formworks. For a long time, the formwork has faced the common problem of grout leakage in the joints during pouring concrete construction, which has always affected the quality of engineering construction and the environment and civilization of the job site. . [0003] For reducing and avoiding the grout leakage of the joints of building formwork in pouring concrete construction, what take in the prior art is all at the construction site, and the gap between each formwork is pasted with sealing tape. But there are following problems in adopting seali...

AI Technical Summary

Problems solved by technology

[0004] 1. Manually pasting the sealing tape is labor-intensive and time-consuming;

[0005] 2. After removing the formwork, the adhesive tape is still stuck on the formwork and it is difficult to remove. Even after the tape is removed, the adhesive layer left on the formwork is not easy to remove, and it will be full of sand and dust, which will affect the effect of the tape when the formwork is used next time;

[0006] 3. Can not completely solve the unevenness of the joints of the formwork, which affects the appearance of the concrete surface
