Dry type connecting device used for fabricating type composite wall vertical seam

Abstract

The invention provides a dry type connecting device used for a fabricating type composite wall vertical seam. The device comprises a connecting sleeve, the connecting sleeve is horizontally embedded on the end of a first wall body, the end of the connecting sleeve is flush with the end of the first wall body, a connecting box body is horizontally buried on the end of the second wall body, the endof the connecting box body is flush with the end of the second wall body, a connecting bolt is horizontally mounted between the connecting sleeve and the connecting box body, one end of the connectingbolt is fixedly connected with the connecting sleeve, the other end of the connecting bolt is fixedly connected with the connecting box body, the connecting box body is pre-buried on the end of the vertical seam of the wall, the connecting box body has the good bearing capacity, reliable connection of the vertical seam of the adjacent walls can be achieved, the wall vertical seam connection is achieved only through connection of a single-side wall body through a connecting bolt, the damage to the wall can be reduced, the connecting device is concentrated in damage under the strong earthquake,assembling mounting and later-period repair are easy, and the advantages of being high in precision, shortening the construction period, and capable of easily repairing the joint after the earthquakeare achieved.

Description

technical field [0001] The invention belongs to the technical field of border connection of assembled composite walls, and in particular relates to a dry connection device for vertical joints of assembled composite walls. Background technique [0002] Prefabricated buildings have the characteristics of standardization of design, industrialization of component production, and mechanization of construction. Through prefabricated construction, on-site wet work and the use of labor can be greatly reduced, which is the main development direction of future buildings. The key to prefabricated composite wall structures lies in the prefabricated components. Space and boundary connection technology between prefabricated components and cast-in-place and post-cast concrete, including the selection of connection joints and the structural design of connection nodes. [0003] At present, the existing prefabricated wall panel connection technology can be divided into wet connection and dry ...
