Integrated slurry-leaking-preventing filling material

Abstract

The invention relates to an integrated slurry-leaking-preventing filling material comprising a base and further comprising a baffle. The base is made of a flexible material and is adaptable to the size of the interior of a pre-buried channel, the width of the baffle is adaptable to that of the pre-buried channel, and the baffle is connected with the base through a connecting neck. The width of theconnecting neck is adaptable to an opening of the pre-buried channel, and a gridding cloth is arranged at the end, away from the baffle, of the base. The integrated slurry-leaking-preventing fillingmaterial has the beneficial effects that through improvement forthe structure, the filling material can be filled at a time, so that permeation of concrete can be effectively prevented in the formingprocess of the pre-buried channel, the filling material can be removed at a time as well, thus the filling material can be reused, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of filling materials, in particular to an integrated leak-proof slurry filling material. Background technique [0002] Pre-embedded channel is a kind of building connecting component that is widely used in high-speed rail, subway and building curtain wall projects to replace traditional anchor bolts. In the existing pre-embedded channels, in order to prevent the slurry leakage of the pre-embedded channels during the installation of concrete, the pre-embedded channels usually need to be filled with foam, and equipped with plastic plugs at the end of the channel and the opening surface of the channel. tape to ensure internal tightness. [0003] The early embedded channel filling foam was made of polystyrene foam, and sharp iron parts were used when removing it. On the one hand, it was easy to scratch the surface coating of the embedded channel. Complete removal is laborious and labor-intensive, and the work efficiency...

AI Technical Summary

Problems solved by technology

[0003] Early embedded channels were filled with polystyrene foam, and sharp iron parts were used to remove them. On the one hand, it is easy to scratch the surface coating of the embedded channel, and on the other hand, polystyrene foam is brittle, and it is difficult to complete the foam. Complete removal, laborious and laborious, low work efficiency

[0004] The material of the pre-buried channel filling foam has been improved in the later stage, and it has stronger tensile properties than polystyrene foam, which can basically solve the situation that the filling foam is difficult to remove, but in the final packaging process of the product, it still needs to be filled The installation of all filling materials is completed in three steps of foam, plug, and tape. When the product is installed and used, it also needs to go through two steps of tearing off the tape and removing the foam. The operation process is cumbersome and the work efficiency is low.

At the same time, during the installation of the pre-embedded channel, due to changes in the temperature and alkaline environment of the curing environment, the viscosity of the tape will be directly affected, and the coating of the pre-embedded channel may be adversely affected when the tape is removed.
