A kind of inner wall connecting structure and construction method thereof

Abstract

The invention discloses an interior wall connection structure, comprising at least a prefabricated wall composed of a first wall, a second wall and a support arranged between the first wall and the second wall; a distance is provided between the bottom of the support and the bottom of the first and second wall to configure a concrete casting-in-place space filling between the first wall and the second wall, and at least part of the casting-in-place space is configured to the edge of the prefabricated wall; a keyway structure is configured between the support and the casting-in-place space and comprises keyways arranged at even intervals, and a plane terrace is formed between the adjacent keyways; a concrete casting passage communicated with the casting-in-place space is also configured in the prefabricated wall; the interior wall connection structure comprises a concrete casting space between two adjacent prefabricated walls and a casting-in-place space with the two prefabricated walls configured to its edge; the connection structure of the invention provides greatly improved mounting integrity and connection strength for a wall.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an inner wall connection structure and a construction method thereof. Background technique [0002] The wall structure of the existing building comprises two wall bodies arranged at intervals, and a plurality of criss-crossing steel bars are arranged between the two wall bodies, and then poured with concrete to form a complete prefabricated wall body structure. When the two wall structures are combined to form a node, the transverse steel bars of the two need to be bound and then poured. However, since the concrete of the node is poured later, the integrity of the wall connection node is poor, resulting in low strength. Moreover, if the bottom of the wall is not on the same plane, it needs to be filled with mortar to smooth it out. The isolation layer produced by the mortar has poor bonding with the concrete, resulting in a decrease in strength. In addition, for the prefa...

AI Technical Summary

Problems solved by technology

[0003] 1. The strength of the wall structure is poor;

[0004] 2. The space between the two walls needs to be filled during on-site pouring. The process is time-consuming, and the on-site construction time is tight, the process is simple, and the quality of the poured wall is difficult to guarantee;

[0005] 3. Due to the problems of the pouring material itself or the construction process, the concrete is prone to air bubbles during the pouring process and is not easy to be discharged. After the pouring is completed, many pits will be formed, which will affect the quality of the finished prefabricated inner wall.

[0006] 4. The material and process of the grouting structure are unstable, time-consuming and labor-intensive, and the strength, integrity, and safety are poor
