Assembled type shear wall upper-layer and lower-layer combined connection structure

Abstract

The invention discloses an assembled type shear wall upper-layer and lower-layer combined connection structure which comprises an upper-layer prefabricated wall and a lower-layer prefabricated wall which are connected in a butted mode. When the upper-layer prefabricated wall and the lower-layer prefabricated wall are connected in the butted mode, a downward-protruding supporting structure of the upper-layer prefabricated wall is supported on the lower-layer prefabricated wall, structural longitudinal ribs of an embedded column of the upper-layer prefabricated wall and structural longitudinal ribs of an embedded column of the lower-layer prefabricated wall are opposite in a one-to-one mode and are connected mechanically, the structural longitudinal ribs I of the upper-layer prefabricated wall and the structural longitudinal ribs II of the lower-layer prefabricated wall are connected in an overlapped mode, and the upper-layer prefabricated wall and the lower-layer prefabricated wall are connected at the joint through a cast-in-place concrete structure. The combined connection way combined with the cast-in-place concrete structure is formed through mechanical connection, steel bar splicing and concrete spraying, the wall prefabrication technology is simpler, on-site construction is more convenient and rapider, and the workpiece manufacturing cost and the construction cost can be reduced.

Description

technical field [0001] The invention relates to the field of building structures, in particular to an assembled connection structure of upper and lower layers of a prefabricated shear wall. Background technique [0002] At present, the traditional cast-in-place shear wall structure has problems such as heavy on-site workload, waste of building materials, waste of building water, and serious environmental pollution. The vertical connection structure of prefabricated shear walls mostly adopts sleeve grouting connection, steel bar welding connection and indirect lap joint grouting anchor connection. Sleeve grouting connection has problems such as high sleeve cost and not suitable for the use of steel bars with thinner cross-sections; steel bar welding connection has problems such as large welding workload on site and difficult to guarantee welding quality; indirect lap joint grout anchor connection has problems on site Difficult construction, hard to guarantee the forming qual...

AI Technical Summary

Problems solved by technology

Sleeve grouting connection has problems such as high sleeve cost and not suitable for the use of steel bars with thinner cross-sections; steel bar welding connection has problems such as large welding workload on site and difficult to guarantee welding quality; indirect lap joint grout anchor connection has problems on site Difficult construction, hard to guarantee the forming quality of reserved holes, etc., and sleeve grouting connection and indirect lap joint grout-anchor connection are dry connections. If not handled properly, stress concentration is prone to occur at horizontal joints, forming a weak section , affecting the overall performance of the structure
