Problems solved by technology

[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.

Embodiment 1

[0015] see Figure 1-2 , which includes the inner formwork 1 and outer formwork 2 located on both sides of the shear wall reinforcement that has been bound and accepted by the supervisor, and the upper row of support reinforcement 3 and the lower row of support reinforcement 4 that have been pre-implanted in the shear wall, The inner formwork 1 and the outer formwork 2 are connected and fixed into one body through screw rods 5, and 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, and the lower row of support A second positioning plate 7 is fixed on the outer surface of the steel bar 4, and several grooves 8 for placing jacks 9 are provided on the upper top surface of the first positioning plate 6, and the piston shaft ends of the jacks 9 are pushed against the outer formwork. At the lower bottom surface of 2, a pin shaft 10 is arranged on the upper top surface of the first positioning plate 6, and...

Embodiment 2

[0021] First, the first positioning plate 6 and the second positioning plate 7 are respectively docked with the upper row of supporting steel bars 3 and the lower row of supporting steel bars 4, and then the first bolts 63 and the second bolts 73 are tightened and locked respectively. In this state, the first Positioning plate 6 can also be used as operating platform;

[0022] Then insert the bottom of the hydraulic jack 9 into each corresponding groove 8, then adjust the piston shaft end of the jack 9 to a uniform level;

[0023] Then the inner formwork 1 and the outer formwork 2 are hoisted to designated positions respectively, wherein the outer formwork 2 is directly placed on the piston shaft end of the jack 9, and then the inner formwork 1 and the outer formwork 2 are initially fixed by means of the screw pull rod 5 In this process, the alignment of the screw holes of the outer formwork 2 and the inner formwork 1 can be adjusted through the jack 9 to adjust the height of ...

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...
