[0004] However, as for the current traditional formwork tensioning and fastening device, the formwork is usually fixed by screwing the nut of the tensioning screw. However, in the process of disassembling the formwork tensioning and fastening device, the staff needs to use tools to screw the nut to release the fixation of the formwork, and then pull out the tensioning screw. The operation is relatively cumbersome. At the same time, due to the moisture in the concrete, the tensioning screw is prone to rust after being separated from the moisture for a long time, which makes the nut difficult to unscrew and inconvenient to use. Utility Model Content

[0005] In view of this, the utility model provides a formwork tensioning and fastening device, which has a first locking seat and a second locking seat that can facilitate the staff to quickly release the formwork fixation. After the concrete is formed, the staff can toggle the limit slide to make the limit slide slide in the rotating seat and squeeze the reset spring. As the limit slide slides, it will slowly disengage from the limit slot. At this time, the staff can twist the rotating seat to stand up the rotating seat, release the limit between the first connecting seat and the second connecting seat, and separate the first connecting seat and the second connecting seat.

[0006] The utility model provides a template tensioning and fastening device, which specifically includes: a fixing rod; a water-stop steel plate is fixedly connected to the center of the outside of the fixing rod; two tensioning screws are symmetrically arranged on the outside of the fixing rod; the right parts of the two tensioning screws are threadedly connected to a first locking seat; the left parts of the two tensioning screws are threadedly connected to a second locking seat; the two second locking seats are respectively aligned with the positions of the two first locking seats; the outsides of the two first locking seats on the left are fixedly connected to a group of first connecting seats; the outsides of the two second locking seats on the right are fixedly connected to a group of second connecting seats; the two groups of second connecting seats are respectively aligned with the positions of the two groups of first connecting seats.

[0012] Beneficial effects

[0013] The utility model discloses that when disassembling the template tensioning and fastening device, it is only necessary to pull the limiting slide to disengage the limiting slide from the limiting slot, and then twist the rotating seat to stand up the rotating seat, thereby releasing the limit between the first connecting seat and the second connecting seat. At this time, the staff can disassemble the first connecting seat and the second connecting seat into two halves and quickly remove them from the tensioning screw rod. The operation is simple and fast, which effectively improves the convenience of the template tensioning and fastening device, reduces the labor intensity of the staff, and is more convenient to use.
