Problems solved by technology

The integrity of the wet connection is good, but the construction is inconvenient. If the steel sleeve grouting connection is used, there is still no effective inspection method for the quality inspection of the sleeve grouting connection.
Compared with the wet connection, the existing dry connection has the characteristics of convenient construction, but the connection method is still relatively complicated, requiring corresponding tightening, tensioning, welding and other work
Since the prefabricated toilet or prefabricated kitchen is connected between the main body of the upper and lower buildings, and the overall rigidity of the prefabricated toilet or prefabricated kitchen is high, if effective measures are not taken to avoid the influence of the prefabricated toilet or prefabricated kitchen on the rigidity of the main building, the vertical Increase the design stiffness of the original building in the horizontal and lateral areas, which will have a negative impact on the earthquake resistance of the building

Embodiment 1

[0035] Such as figure 1 As shown, the construction method of the flexible connection structure between the prefabricated component and the main body of the building in this embodiment, wherein the flexible connection structure between the prefabricated component and the main body of the building includes a multi-layer cast-in-place building main body 2 arranged at intervals from top to bottom, two adjacent existing Prefabricated components 1 are connected between poured building main bodies 2 . In this embodiment, the main body 2 of the cast-in-place building is a floor slab, and the prefabricated component 1 is a prefabricated toilet. The lower parts of the four side walls of the prefabricated component 1 shrink inward to form a tenon 11 , and the upper part of the prefabricated component 1 forms the main body of the prefabricated component. A suspension hook 4 is pre-embedded in the upper part of the prefabricated component body.

Embodiment 2

[0045] Such as figure 2As shown, the construction method of the flexible connection structure between the prefabricated component and the main body of the building in this embodiment, wherein the flexible connection structure between the prefabricated component and the main body of the building includes a multi-layer cast-in-place building main body 2 arranged at intervals from top to bottom, two adjacent existing Prefabricated components 1 are connected between poured building main bodies 2 . In this embodiment, the main body 2 of the cast-in-place building is a floor slab, and the prefabricated component 1 is a prefabricated toilet. The lower parts of the three side walls of the prefabricated component 1 shrink inward to form a tenon 11 , and the upper part of the prefabricated component 1 forms the main body of the prefabricated component. The upper part of the main body of the prefabricated component is pre-embedded with a hook 4 . The outer wall of the unshrunk side wa...

Abstract

The invention discloses a construction method of a flexible connecting structure between prefabricated components and building bodies. The construction method comprises the following steps that S1, the lowermost building body is poured; a mortise groove is formed in the top surface of the building body; S2, the prefabricated components are inserted into the cast-in-place building body in a supporting mode; a tenon matched with the mortise groove is arranged at the lower end of the prefabricated components; S3, a first flexible layer for lowering the connecting rigidity between the prefabricated components and the upper cast-in-place building body is laid on the top surfaces of the inserted prefabricated components; S4, the upper building body is poured on the first flexible layer; and S5,the steps S2-S5 are repeated to complete the flexible connection between the prefabricated components and the building bodies. According to the construction method of the flexible connecting structurebetween the prefabricated components and the building bodies, the flexible connection between the prefabricated components and the building bodies is realized, and the influence of the prefabricatedcomponents on the rigidity of the building bodies is avoided.

Description

technical field [0001] The invention belongs to the field of prefabricated building industrialization, and in particular relates to a construction method for a flexible connection structure between a prefabricated component and a building main body. Background technique [0002] Prefabricated parts and components have the characteristics of standardized design, factory production, prefabricated construction, energy saving, environmental protection, shortened construction period, and improved quality. At the same time, they can promote the deep integration of informatization and industrialization. development and application. Prefabricated toilets or prefabricated kitchens can achieve standardized design, factory production, and assembled construction, and have the advantages of integrity and good quality. As an integral prefabricated unit, prefabricated toilets or prefabricated kitchens are used in prefabricated buildings. [0003] At present, there are two methods of prefa...
