[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0016] like Figure 1 As shown, a shear wall formwork reinforcement device includes two adjacent side formworks 1, with a strip connecting plate 2 between the two side formworks 1. The strip connecting plate 2 is composed of several short connecting rods 6 that are inserted end to end. The thickness of the short connecting rods 6 is the same as that of the side formworks 1, and they are made of stainless steel to ensure their service life. The combined short connecting rods 6 have better adaptability to side formworks 1 of different lengths. A longitudinal support rod 3 that fits against the side formwork 1 is provided at the outer end of the connection between adjacent short connecting rods 6. A transverse support rod 4 is provided at the outer end of the longitudinal support rod 3. The transverse support rod 4 is fixedly connected by tie rod bolts 5 passing through the pin hole 9 in the center of the short connecting rod 6.

[0017] like Figure 1 As shown, the connecting short rod 6 includes a plug 7 and a connecting hole 8 that are matched at the beginning and end. When they are connected, they adopt a transition fit to ensure that the adjacent connecting short rods 6 are connected end to end and to prevent them from becoming loose. The pin hole 9 is located in the center of the connecting short rod 6.

[0018] The plug 7 and the connecting socket 8 are triangular in shape. The triangle shape makes it easy for the plug 7 to be inserted into the connecting socket 8 and facilitates disassembly and assembly.

[0019] like Figure 3As shown, the longitudinal support rod 3 includes a longitudinal sleeve 301. Several strip holes 303 are opened on the inner and outer sides of the longitudinal sleeve 301. A wooden inner rod 302 is inserted into the longitudinal sleeve 301, which makes the longitudinal support rod stronger. The multiple strip holes 303 can be embedded and cooperate with the limiting protrusion 10 at the outer end of the connecting short rod 6 to achieve uniform arrangement of the longitudinal support rods 3 and ensure the uniformity of the force on the multiple longitudinal support rods 3.

[0020] The outer end of the connecting hole 8 of the connecting short rod 6 is provided with a limiting protrusion 10 that matches the strip hole 303 of the longitudinal support rod 3.

[0021] The implementation principle of a shear wall formwork reinforcement device according to an embodiment of this application is as follows:

[0022] A strip connecting plate 2 with several pin holes 9 is set between adjacent upper and lower side templates 1. The strip connecting plate 2 can be used to pass through tie rod bolts 5 to tighten the transverse support rods 4, thereby supporting and fixing multiple longitudinal support rods 3 on the inner side. In this way, only tie rod bolts 5 need to be installed on the strip connecting plate 2 for tightening and fixing, without drilling holes in the side template, ensuring the integrity of the side template 1 and ensuring that the side template 1 can be used normally after subsequent demolding.

[0023] Meanwhile, the strip connecting plate 2 is connected by several short connecting rods 6 that are plugged in end to end. It can be assembled according to the length of the side template 1. The longitudinal support rod 3 is supported at the joint of the adjacent connecting rod 6. The strip hole 303 on the inner side of the longitudinal support rod 3 matches the limiting protrusion 10 on the outer side of the connecting rod 6. In this way, the longitudinal support rod 3 presses the joint of the connecting rod 6, and can also achieve the uniform distribution and fixation of the longitudinal support rod 3. It is only necessary to pass the tie rod bolt 5 through the pin hole 9 in the center of the connecting rod 6 to ensure that the tie rod bolt 5 and the longitudinal support rod 3 are installed alternately and evenly, ensuring the neatness of the installation.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
