A kind of reinforcement support structure of shear wall external formwork

Abstract

The invention discloses a reinforced support structure for an outer formwork of a shear wall, which comprises an inner formwork (1) and an outer formwork (2) located on both sides of a shear wall steel bar that has been bound and accepted by a supervisor, and has been implanted in advance. The upper row of support bars (3) and the lower row of support bars (4) in the shear wall, the inner formwork (1) and the outer formwork (2) are connected and fixed into one body through screw rods (5), so A first positioning plate (6) which doubles as an operating platform is fixed on the outer side of the upper row of support bars (3). The present invention is simple in structure, easy to use, and greatly improves the stability of the outer formwork due to the support of the outer formwork by a certain diagonal bracing. The verticality of the outer wall of the force wall is better, especially the outer formwork is not easy to run and expand, which greatly improves the safety during the construction process.

Description

technical field [0001] The invention relates to the technical field related to building construction formwork reinforcement, in particular to a reinforcement support structure for an external formwork of a shear wall. Background technique [0002] The shear wall is a wall that bears the horizontal load and vertical load gravity caused by wind load or earthquake to prevent the structure from being sheared and damaged. In daily construction, due to the high height of the shear wall, in order to avoid the occurrence of multiple pouring Therefore, most of the shear walls are formed by one-time pouring, so the pressure on the formwork is relatively high, and the reinforcement requirements are also higher, especially the outer wall shear wall structure, due to the smooth outer wall The body has no fulcrum that can provide diagonal bracing (according to the requirements of "JGJ130--2011 Safety Technical Specifications for Fastener Type Steel Pipe Scaffolding in Building Constructio...

[0002] The shear wall is a wall that bears the horizontal load and vertical load gravity caused by wind load or earthquake to prevent the structure from being sheared and damaged. In daily construction, due to the high height of the shear wall, in order to avoid the occurrence of multiple pouring Therefore, most of the shear walls are formed by one-time pouring, so the pressure on the formwork is relatively high, and the reinforcement requirements are also higher, especially the outer wall shear wall structure, due to the smooth outer wall The body has no fulcrum that can provide diagonal bracing (according to the requirements of "JGJ130--2011 Safety Technical Specifications for Fastener Type Steel Pipe Scaffolding in Building Construction", the external scaffold is strictly prohibited as the fulcrum of the formwork, and it is forbidden to connect with any formwork), so it can only It is not only difficult to construct, but also difficult to adjust the formwork by planting bars and screw rods. In addition, only the inclined pipe is supported internally. Once it is overturned, it is often impossible to handle, and there is a big safety hazard.
