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

[0017] see Figure 1-3 , which includes an inner formwork 1 and an outer formwork 2 located on both sides of the shear wall reinforcement that has been bound and accepted by the supervisor, and several supporting reinforcement bars 3 that have been pre-implanted in the shear wall. The inner formwork 1 and The outer templates 2 are connected and fixed into one body through screw rods 4; the outer side of the supporting steel bar 3 is provided with a positioning plate 5 which doubles as the first operating platform, and several supplying holes are provided on the side of the positioning plate 5 inwardly. The locating hole 51 that supports steel bar 3 gaps to insert, the lower bottom surface place of described locating plate 5 is provided with the screw hole 52 that communicates with locating hole 51, is provided with in this screw hole 52 and can be screwed with and cooperates with bolt 53; When bolt 53 is completely After being screwed into the screw hole 52, the end of the bol...

Embodiment 2

[0024] First, each positioning hole 51 on the positioning plate 5 is inserted into each corresponding supporting steel bar 3 and locked by bolts 53. In this state, the positioning plate 5 can also be used as an operating platform;

[0025] Then insert the bottom of the hydraulic jack 6 into each corresponding positioning groove 7, then adjust the piston shaft end of the jack 6 to a uniform level;

[0026] Then the inner formwork 1 and the outer formwork 2 are hoisted to the designated positions respectively, wherein the outer formwork 2 is directly placed on the piston shaft end of the jack 6, and then the inner formwork 1 and the outer formwork 2 are initially fixed by means of the screw pull rod 4 In this process, the alignment of the screw holes of the outer formwork 2 and the inner formwork 1 can be adjusted by the jack 6 to adjust the height of the outer formwork 2;

[0027] Then the proofreading and reinforcement work can be carried out. When the diagonal brace proofread...

Abstract

The invention discloses a reinforcing structure for shear wall formworks. The reinforcing structure comprises an inner formwork (1) and an outer formwork (2) on the two sides of shear wall steer barswhich are well bound and are accepted by supervision, and a number of supporting steel bars (3) pre-implanted into a shear wall body. The inner formwork (1) and the outer formwork (2) are connected and fixed together by screw pull rods (4). A positioning plate (5) serving as a first operating platform is arranged on the outer side of the supporting steel bars (3). A number of positioning holes (51) for the supporting steel bars (3) to be inserted into at intervals are arranged inward in a side of the positioning plate (5). The reinforcing structure has a simple structure, and is convenient touse. As certain bracing support is provided for the outer formwork, the stability of the outer formwork is greatly improved. The correction method in the invention is different from the correction method of verticality adjustment through the screw pull rods, so that the verticality of the external wall of a formed shear wall is better, and the safety in the construction process is greatly improved.
