Formwork structure of shear wall corner joint, shear wall cast-in-situ system and construction method

Abstract

A formwork structure of a shear wall corner joint, a shear wall cast-in-situ system and a construction method are disclosed. The formwork structure of the shear wall corner joint comprises a corner external formwork, a corner internal formwork and corner dorsal bars, wherein the corner external formwork is mounted on the outer portion of a shear wall corner, the corner internal formwork is mounted on the inner side of the shear wall corner, and the corner dorsal bars are parallelly mounted on the inner side of the corner internal formwork at intervals in the vertical direction; the horizontal section of the corner external formwork is in an L shape; the corner external formwork is a PCF slab, and comprises an insulation board, an external leaf wall board and external face bricks which are sequentially arranged from inside to outside; horizontally-through grooves are parallelly formed in the outer side surface of the insulation board at intervals in the vertical direction; horizontally-penetrating concrete ribs are arranged on the positions, corresponding to the grooves, on the inner side surface of the external leaf wall board; and the external leaf wall board is tightly attached to the outer side surface of the insulation board, and the concrete ribs on the external leaf wallboard are embedded in the grooves correspondingly. According to the formwork structure of the shear wall corner joint and the shear wall cast-in-situ system and the construction method, the technical problems that when a traditional formwork structure construction is conducted, an external veneer is prone to being damaged, the integrality of external face bricks is poor, and structure attractiveness is poor are solved.

Description

technical field [0001] The present invention relates to a formwork structure of a shear wall corner node, a cast-in-place system of a shear wall and a construction method, in particular to a construction method of a formwork structure of a prefabricated shear wall system for installing exterior facing bricks Pack. Background technique [0002] The prefabricated shear wall structure has developed vigorously in recent years. At present, the commonly used construction method is to use prefabricated components for production and processing in the component factory, and then carry out hoisting construction operations at the construction site. Some projects use exterior facing bricks as the exterior decoration layer of the building, while the exterior facing bricks can be prefabricated on the wall surface together with the prefabricated exterior wall to ensure the integrity of the facing bricks and the outer leaf wall panels. Facing bricks, when there are windows and wall holes o...
