When assembling two adjacent devices, the plug-in block 104 is inserted into the slot 105, and then the two are fixed synchronously to the work location by bolts, so that multiple devices can be spliced ​​end to end into one.

[0020] A plurality of first telescopic rods 2 are vertically fixed to the top of the base 1 along its length direction, and the front end surface of the first telescopic rod 2 is flush with the front end surface of the base 1, thereby increasing the contact area with the disassembly-free template. Specifically, the first telescopic rod 2 includes a first outer tube 201 vertically fixed to the top of the base 1, a first inner rod 202 and a fixing bolt 203 slidably arranged inside the first outer tube 201, and the front end surface of the first outer tube 201 is flush with the front end surface of the first inner rod 202. In this embodiment, the front end surface of the first outer tube 201 is provided with a first inner rod 202 that is flush with the front end surface of the first inner rod 202. 202 are openings of equal width, and both can be tightly attached to the disassembly-free template to provide support for it. A strip through hole 2011 is provided on one side of the first outer tube 201 along its length direction. One end of the fixing bolt 203 passes through the strip through hole 2011 and is threadedly connected to the first inner rod 202, which plays a role of limiting and is convenient for fixing the first inner rod 202. Unscrewing the fixing bolt 203 also facilitates disassembly and assembly. In this embodiment, the fixing bolt 203 and the strip through hole 2011 are both arranged on the inside to avoid affecting the assembly of multiple devices.

[0021] The top ends of the plurality of first telescopic rods 2 are connected by a horizontally arranged connecting cross bar 3, and a plurality of second telescopic rods 4 are obliquely arranged between the back of the connecting cross bar 3 and the base 1, and the top ends of the second telescopic rods 4 are rotatably connected to the connecting cross bar 3, and the bottom ends of the second telescopic rods 4 are rotatably connected to the base 1. Specifically, the second telescopic rod 4 includes a second outer tube 401 and a second inner rod 402 movably inserted into the second outer tube 401, the bottom end of the second outer tube 401 is rotatably connected to the base 1, the top end of the second inner rod 402 extends to the outside of the second outer tube 401 and is rotatably connected to the connecting cross bar 3, and when the connecting cross bar 3 moves up and down, it drives the second inner rod 402 to slide back and forth inside the second outer tube 401. Furthermore, in order to improve the stability of the device, a fixing bolt can be provided at the top end of the outer side of the second outer tube 401 to tighten the second inner rod 402 inside.

[0022] A support rod 5 is arranged between the first telescopic rod 2 and the second telescopic rod 4, and the support rod 5 includes a fixing rod 501 fixed horizontally to the side of the first telescopic rod 2 close to the second telescopic rod 4, a threaded rod 502 fixed to one end of the fixing rod 501 and two nuts 503 threadedly connected to the threaded rod 502. The second telescopic rod 4 is penetrated by a sliding hole 403 along its length direction for accommodating the threaded rod 502 to slide up and down. The two nuts 503 are respectively located at the front and rear ends of the second telescopic rod 4. When the connecting cross bar 3 moves up and down, the second telescopic rod 4 is driven to rotate, and the threaded rod 502 moves relatively inside the sliding hole 403. The positions of the two nuts 503 are adjusted, and the second telescopic rod 4 is clamped in the middle, which can provide support for the middle section of the non-disassembly template and have higher stability.

[0023] Working principle: When in use, the front end face of the first telescopic rod 2 is pressed against the surface of the non-disassembly formwork, and the bolt passes through the mounting hole 103 to fix the base 1 at the work site. The second telescopic rod 4 is installed obliquely between the base 1 and the connecting cross bar 3 to improve the stability of the device, provide support for the non-disassembly formwork, and prevent the non-disassembly formwork from being deformed by the pressure of concrete. When it is necessary to support the non-disassembly formwork of different heights, drive the first inner rod 202 to slide up and down inside the first outer tube 201 until the connecting cross bar 3 abuts against the top of the non-disassembly formwork. At this time, the second inner rod 402 slides up and down inside the second outer tube 401, and the threaded rod 502 slides inside the give-way sliding hole 403. After adjusting the position, tighten the fixing bolt 203 to fix the first inner rod 202, rotate the nut 503, and clamp the second telescopic rod 4 between the two nuts 503 to support the non-disassembly formwork in the middle section.
