Description

Technical Field

[0001] The utility model relates to the technical field of concrete formwork, and particularly relates to a limit clamping and fixing device for cast-in-place concrete formwork in building construction. Background Technique

[0002] The cast-in-place concrete formwork is the formwork used during the concrete pouring, also known as the cast-in-place slab, formwork board, etc. Its main function is to provide support and positioning for the concrete pouring process to ensure that the concrete can solidify according to the predetermined shape and size. At the same time, the cast-in-place concrete formwork can also affect the quality of the concrete to a certain extent.

[0003] The existing technical solution proposed the publication number: CN215948904U, a limit clamping and fixing device for cast-in-place concrete formwork in building construction. By setting two clamping members, the top of the formwork is clamped by using the first clamping plate and the movable second clamping plate. Then, by screwing the threaded rod of the connecting rod, the slider moves to drive the second clamping member to move towards the first clamping member to achieve the fixation of the distance and the initial positioning position of the top of the formwork.

[0004] In order to solve the problem that during the concrete pouring process, the formwork is prone to offset due to the lateral pressure of the concrete, and thus fails to meet the specified size requirements and cannot be used. The existing technology is to adopt a method of using the cooperation of a connecting rod, a first clamping member, a second clamping member, a limiting plate, a first clamping plate, a second clamping plate and a screw. However, there will still be a situation where after the limit clamping of the concrete formwork during the pouring process, it is not easy to disassemble, resulting in the clamping mechanism being unable to be used again, thus reducing the practicality of the clamping mechanism.

On the other side of the W-shaped clamping block 51, a nut 52 is threadedly connected. Through the pin connection between the concrete formwork main body 1 and the assembly side plates 2, the convenient assembly of the formwork is facilitated. Then, the clamping plate 3 and the side clamping plates 4 are installed in sequence. Using the side clamping plates 4 as a carrier to install the fixed baffle 5, and using the sleeve 6 for through connection, the threaded sleeve of the threaded rod 53 inside it increases the internal support of the mold. Then, with the drive of the W-shaped clamping block 51, the clamping bottom block 511 is clamped inside the fixing groove 50. Due to the resilience of the reset spring post 501, the pushing block 502 is pushed to clamp the clamping bottom block 511, achieving the function of clamping installation.

Then, it is threadedly connected with the nut 52 to facilitate the limit fixation of the threaded rod 53 and achieve the function of fixed clamping, improving the stability of the mold. The fixed baffle 5 is sleeved inside the socket 42 with the insertion column and the push column 44 is rotated threadedly. The push column 44 is used to push the clamp 43 for pressing tightly to achieve the function of fixing and clamping the insertion column, so as to facilitate the convenient installation and disassembly of the side clamping plate 4 and the fixed baffle 5, which is beneficial to the recycling of the fixing mechanism.
