Abstract

The invention relates to a sub-frame post-cast joint with an external permanent aluminum plate outer mold. The sub-frame post-cast joint mainly comprises a sub-frame column, steel bar connection sleeves, aluminum plate connectors, an external aluminum plate, a prefabricated grouting material opening, a steel screen and connecting bolts. The post-cast joint is arranged on the sub-frame column to separate the sub-frame column into two parts. The aluminum plate connectors are welded to the upper reinforcing steel bars and the lower reinforcing steel bars of the sub-frame column, and the upper reinforcing steel bars and the lower reinforcing steel bars are connected through the steel bar connection sleeves. The prefabricated grouting material opening is welded in one upper reinforcing steel bar of the sub-frame column. The external aluminum plate is fixedly connected with the aluminum plate connectors through the connecting bolts and self-fixed in an enclosed manner through anchoring screws. Grouting material fills the space formed by the external aluminum plate and the steel screen in an enclosed manner. A leveling concrete layer is arranged outside the external aluminum plate. The sub-frame post-cast joint has the advantages that a main structure and a sub-structure are completely disconnected first to allow the main frame to subside sufficiently and allow a sub-frame to be unstressed, and structure safety is guaranteed. The invention further provides a construction method of the sub-frame post-cast joint.

Description

technical field [0001] The invention relates to a post-cast node and a construction method of a secondary frame with a permanent aluminum plate external formwork. It belongs to the field of main structure engineering, and is suitable for super-high structural systems with high requirements on bearing capacity and strict requirements on the shape and size of buildings. Background technique [0002] With the development of the construction industry, there are more and more beautiful and individual super high-rise buildings, but the premise is that the safety of the structure must be guaranteed. Different parts of the structure carry out different force divisions according to their own bearing capacity, which can greatly improve the bearing capacity of the structure. Setting post-cast nodes in the structural system is just the way to solve the division of labor of different components. [0003] For example, the lattice frame of the peripheral structure in a super high buildin...
