Connecting node for superposed sandwich wall side wall and prefabricated base plate

Abstract

Provided is a connecting node for a superposed sandwich wall side wall and a prefabricated base plate. The end of the prefabricated base plate is made to be L-shaped, the vertical side of the end of the L-shaped prefabricated base plate is higher than the bottom of the superposed sandwich wall side wall for a certain height, the outer side of the vertical side of the end of the L-shaped prefabricated base plate is a soil retaining face, the bottom and a bottom stirrup of the superposed sandwich wall side wall are installed on the inner side of the vertical side of the end of the L-shaped prefabricated base plate, a steel wire cage, framework steel bars and horse stool ribs are installed between the inner side of the vertical side of the end of the L-shaped prefabricated base plate and the bottom of the superposed sandwich wall side wall, and the inner side of the vertical side of the end of the L-shaped prefabricated base plate and the bottom of the superposed sandwich wall side wall are connected and fixed to form a formed whole through cast-in-place concrete. A building shear force and an external earthwork extrusion force are effectively resisted by heightening and thickening the connecting structure for the superposed sandwich wall side wall and the prefabricated base plate, and the structural strength and waterproof properties of the connecting node are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a connection node between a side wall of a laminated sandwich wall and a prefabricated bottom plate. Background technique [0002] The existing waterproof connection structure between the side wall of the laminated sandwich wall and the prefabricated floor is realized by installing a waterproof steel plate in the cast-in-place layer at the bottom of the laminated sandwich wall and the upper part of the prefabricated floor. , easy to break, poor structural strength, affecting the waterproof performance and construction quality of the building. Contents of the invention [0003] The technical problem to be solved by the present invention is: to solve the above-mentioned existing problems in the prior art, and to provide a connection node between the side wall of the laminated sandwich wall and the prefabricated floor, and a connection structure betwee...
