The same is true for the second connecting tube 13, which will not be elaborated here. Compared with traditional support devices on the market, the present device eliminates the need for embedded parts in use, thereby avoiding the tilt of the lower end of the subsequent support device and the embedded parts.

[0043] Specifically, Figures 1 to 10As shown, the right end of the connecting rod 3 is rotatably installed with an adjusting rod 2, and two rotating rings 21 are rotatably installed on the circumferential surface of the adjusting rod 2, and an O-ring 22 is rotatably installed on the circumferential surface of the rotating ring 21. Three sleeves 7 are arranged inside the shear wall formwork 1, and the three sleeves 7 are in a horizontal state. The position where the connecting rod 3 and the threaded connecting rod 6 are rotatably connected is installed inside the lowermost sleeve 7, and a threaded rod 11 is slidably installed inside the two sleeves 7 in the middle and upper parts of the shear wall formwork 1, and the two ends of the threaded rod 11 extend outside the sleeve 7; the two ends of the threaded rod 11 are located on the outside of the shear wall formwork 1 and are installed with mounting seats 10, and nuts 12 are rotatably installed on the circumferential surface of the threaded rod 11 located outside the mounting seat 10; the shear wall A first connecting tube 8 is arranged between the mounting seat 10 close to the connecting rod 3 and the O-ring 22 close to the left end of the adjusting rod 2 on the right side surface of the template 1, and a second connecting tube 13 is arranged between the mounting seat 10 away from the connecting rod 3 and the O-ring 22 close to the right end of the adjusting rod 2 on the right side surface of the shear wall template 1, and screws 81 are rotatably installed at both ends of the first connecting tube 8 and the second connecting tube 13, and connectors 9 are rotatably installed at the ends away from the screws 81; the connectors 9 at both ends of the first connecting tube 8 are combined with the mounting seat 10 close to the connecting rod 3 and the O-ring 22 close to the left end of the adjusting rod 2, and the connectors 9 at both ends of the second connecting tube 13 are combined with the mounting seat 10 away from the connecting rod 3 and the O-ring 22 close to the right end of the adjusting rod 2.

[0044] By adopting the above technical scheme, the traditional support device on the market, during use, is embedded in the U-shaped iron ring on the floor slab surface, so that it can be combined with the subsequent support device. Because it is an embedded part, after the first layer of columns or shear wall formwork 1 is cast, the support device needs to be disassembled, and after disassembly, its embedded parts need to be cut by a cutting device to make its top and the concrete slab surface at the same height, which wastes materials and takes a long time to cut; secondly, during the use of the traditional support device on the market, most of them are to install a support rod, make multiple adjustments, and then install another support rod, which is a relatively time-consuming process; during the use of the device, the connecting rod 3, the screw The action of the grooved connecting rod 6 can save the tedious subsequent cutting operation and avoid the subsequent leakage of the board surface. Secondly, during use, you only need to rotate the adjusting rod 2 to allow the rotating ring 21 to push the connecting head 9 to be synchronously close to the shear wall formwork 1, and then the connecting head 9 pushes the screw 81, and then pushes the first connecting tube 8 and the second connecting tube 9 to push the upper end of the screw 81 to be synchronously close to the shear wall formwork 1, so as to support the shear wall formwork 1. The cooperation of the device in the above structure can enable the supporting device to synchronously support the upper end and the middle part of the shear wall formwork 1 under the action of the rotating adjusting rod 2, thereby avoiding the subsequent situation that the upper end of the shear wall formwork 1 is not in the same straight line as the middle part.

[0045] Working principle: First, the left end of the connecting rod 3 is installed inside the sleeve 7, and then the lower end of the vertical plate 4 is installed inside the installation groove 35, and the lower end of the diagonal support plate 5 is installed inside the limiting groove 34, so that the left side of the vertical plate 4 fits with the right side of the shear wall formwork 1.

[0047] Secondly, the threaded rod 11 is installed inside the remaining two sleeves 7 , and then the mounting seats 10 are installed at both ends of the threaded rod 11 , and the mounting seats 10 are fixed by nuts 12 .

[0048] Finally, the screw rods 81 are rotated and installed at both ends of the first connecting tube 8, so that the screw rod 81 at the upper end is combined with the connecting head 9 and the mounting seat 10, and the connecting head 9 at the lower end is combined with the O-ring 22.

[0049] Finally, the adjusting rod 2 is rotated so that the rotating ring 21 can push the upper ends of the first connecting pipe 8 and the second connecting pipe 13 gradually approach the shear wall formwork 1, thereby eliminating the need for construction workers to adjust the devices one by one.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
