Abstract

The invention relates to the field of sealing of general structures of buildings, in particular to a concrete structure post-positioned instant sealing sleeve assembly and a using method thereof. The concrete structure post-positioned instant sealing sleeve assembly comprises a sleeve (1) and is characterized by further comprising a front pressing ring (2), an outer rubber sealing piece (3), a rear pressing ring (4) and a pressing cover (5), the front pressing ring (2), the outer rubber sealing piece (3) and the rear pressing ring (4) are all annular and sequentially sleeve outer side face of the sleeve (1), and the pressing cover (5) sleeves the rear end of the sleeve (1) through the open end and is screwed on the outer side face of the rear pressing ring (4) through internal threads. The using method of the concrete structure post-positioned instant sealing sleeve assembly is characterized by the following steps in sequence that (1) assembling is carried out; (2), holes are plugged; and (3), the cover is screwed. The construction is fast, and the sealing performance is good.

Description

technical field [0001] The invention relates to the field of sealing used in general structures of buildings, in particular to a concrete structure post-mounted instant sealing bushing assembly and its application method. Background technique [0002] In the construction process of the structure at this stage, when there are missing casings in the construction of floors, shear walls, etc., or when openings are required to be added later due to design changes and processes, the traditional method is to use water drills to open holes, and then put the casings in after the holes are completed. , after the pipeline installation is completed, the method of plugging with mold mortar is carried out. The specific steps are as follows: [0003] 1. Chisel the cave wall, clean up the garbage and dust, rinse it with clean water, moisten it for more than 24 hours, then support the roof formwork or hang the formwork, rinse it again with clean water after the formwork is supported, and the...
