Leaking stoppage method for abutted seam of fabricated building precast beam and precast composite floor

Abstract

The invention relates to a fabricated building. A leaking stoppage method for an abutted seam of a fabricated building precast beam and a precast composite floor comprises the steps that the precast beam and the precast composite floor are mounted, bolt holes are formed in the positions close to the precast beam, and bolts are pre-buried; a leaking stoppage component is mounted and is a rigid L-shaped component, the two outer side faces of the leaking stoppage component are flexible waterproof material faces, through holes corresponding to the bolt holes are formed in the attaching positions of the flexible waterproof material faces and the precast composite floor, the flexible waterproof material faces on the outer side of the component are matched with the bottom of the composite floor with certain extrusion force through manual adjusting to complete vertical compaction, and then through transverse horizontal adjusting, the flexible waterproof material faces of a blocked seam of thecomponent are matched with the precast beam to achieve transverse compaction; and the component is screwed at the bolt holes in the precast composite floor through the bolts to be fixed, and then mounting is completed. On-site construction is facilitated, the hidden danger that rubber strips are impacted and then fall off is avoided, and the safety and stability of the blocked seam are greatly improved. The time of solidification shaping needed by sealing the rubber strips is avoided.

Description

technical field [0001] The invention relates to a prefabricated building, in particular to a joint between prefabricated beams and prefabricated laminated floor slabs of the prefabricated building. Background technique [0002] For the caulking measures for the joints of the existing prefabricated building components, the joints of the two components are generally bonded with building-specific sealants so that the gaps between the structures can be blocked. This measure is to a certain extent It effectively solves the leakage problem when the concrete is poured twice between the component joints, but when it is applied to specific large-scale construction projects, there are the following problems: [0003] In terms of specific construction, manual application of sealant is greatly affected by human factors, and it is easy to apply unevenly and even cause certain leakage, which will lead to uneven contact edges between the two components during the second pouring and affect ...

AI Technical Summary

Problems solved by technology

[0006] In terms of mechanical properties, the sealant is greatly affected by its own material properties. During the second grouting, due to the self-weight of the concrete itself and the vibration, the colloid will have a horizontal impact force, which may cause the sealant strip to fall off due to the impact and fail to achieve sealing.
