Technical Field

[0001] This utility model relates to the field of construction, and in particular to a formwork fixing device for construction projects. Background Technology

[0002] An existing patent (publication number: CN217400359U) discloses a fixing device for formwork in construction engineering, including a base plate and fixing piles. The base plate is provided with a fixing mechanism, which includes a support plate slidably connected to the base plate. One end of the support plate has a slot, and the other end of the support plate is provided with a first telescopic component rotatably connected to the support plate. The support plate is also provided with a second telescopic component rotatably connected to the support plate. The end of the second telescopic component is connected to the first telescopic component. However, this device can only support the formwork and cannot strengthen the positioning of the connection between adjacent formworks, which makes it easy for misalignment gaps to appear between adjacent formworks, resulting in unstable fixing and affecting the concrete pouring and forming effect, thus having drawbacks. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a formwork fixing device for construction projects. This device increases the strength of the formwork joints, ensuring the stability and safety of the formwork during concrete pouring, preventing tilting and deformation, and guaranteeing the concrete pouring and forming effect. Furthermore, it is easy to assemble and disassemble, improving the efficiency of formwork fixing operations in construction projects, and is reusable, thus saving construction costs.

[0004] The objective of this utility model is achieved through the following technical solution:
