Prefabricated formwork for concrete interfaces of different strength grades and its construction method

Abstract

The invention discloses a prefabricated formwork for concrete interfaces of different strength grades and a construction method thereof, comprising a prefabricated formwork for connecting beam members and vertical members, the prefabricated formwork consists of a plurality of steel mesh sheets vertically stacked one after another The mesh assembly, the prefabricated concrete connection section located in the lower half of the mesh assembly, the short section steel vertically pierced at the centroid position of the upper half of the mesh assembly, and the longitudinal reinforcement vertically pierced on the mesh assembly and connected to the beam member The corresponding horizontal longitudinal reinforcement and the side bracing reinforcement obliquely arranged on one side of the upper half of the mesh assembly are used to connect the beam members. The invention solves the problem that the concrete strength grades of the vertical member and the horizontal member are different and the construction is difficult when the beam height is high, and the prefabricated formwork greatly facilitates the construction and improves the construction quality.

Description

technical field [0001] The invention relates to a prefabricated formwork, in particular to a prefabricated formwork used for concrete interfaces of different strength levels. Background technique [0002] In high-rise or some super high-rise buildings, the concrete strength grade of vertical members (such as walls or columns) tends to be higher, while the concrete strength grade of horizontal members (such as beam members) is lower and does not need to be raised to the same strength grade. The height of the beams connecting two concrete shear wall piers is often high. In order to ensure the integrity of the structure, the walls or columns are often poured together with the beams. [0003] When the height of the beam is high, and the concrete strength grades of the beam member and the vertical member are inconsistent, in order to ensure that the concrete of different strength grades of the two members does not mix with each other, the traditional construction technology is t...

Problems solved by technology

However, when the beam height is high, the steel wire mesh will not bear the huge lateral pressure of the concrete, resulting in grout leakage, and in severe cases, the entire steel mesh will be torn
