Description

Technical Field

[0001] This utility model relates to the field of formwork reinforcement technology in building engineering, and more specifically to a device for reinforcing formwork in building engineering. Background Technology

[0002] In the construction process, formwork reinforcement is a crucial step in ensuring the quality of concrete pouring. Existing formwork reinforcement methods mostly employ traditional steel pipe and coupler combinations, or tie bolts combined with materials such as timber and channel steel. However, these traditional methods have many shortcomings. For example, steel pipe and coupler combinations are cumbersome to install and dismantle, requiring significant manpower and time, and the couplers are prone to loss. While tie bolts provide some reinforcement, they leave holes in the concrete surface after removal, affecting the aesthetics and requiring subsequent repairs, increasing construction costs and time. Furthermore, traditional reinforcement methods are ineffective for complex-shaped formwork, such as curved or irregularly shaped formwork, leading to deformation and bulging during concrete pouring, affecting the dimensional accuracy and appearance of the concrete components. Therefore, developing a simple-to-operate, highly effective, and widely applicable formwork reinforcement device for construction projects is of significant practical importance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] First Embodiment

[0026] Please see the appendix Figure 1-3 This utility model discloses a device for reinforcing formwork in building engineering, comprising: a support plate 1, a steel cable 2, and a locking device 3;

[0027] The support plate 1 has a square structure, and it is preferable to use four pieces;

[0028] Both ends of the steel cable 2 are connected to the steel cable fixing block 200 by threads;

[0029] When in use, the fixing block 200 can be rotated and removed. At this time, the steel cable 2 can pass through multiple locking devices 3 to achieve the purpose of fixing the engineering template.

[0030] The locking device 3 includes a cover 300, a central column 301, a tightening shaft 303, and a base 304;

[0031] The cover 300 has a through hole in the center, through which the steel cable 2 can pass to achieve the purpose of connection.

[0032] The bottom is provided with a connecting plate 308, which has internal threads and can be threaded to the tightening shaft 303.

[0033] One end of the central column 301 passes through a through hole in the cover 300, and the other end is fixedly connected to the bottom of the tightening shaft 303.

[0034] The tightening shaft 303 has a thread on its top outer circumference, and notches at opposite ends. The bottom is fixedly connected to a tightening shaft fixing block 305; there are several tightening shaft fixing blocks 305.

[0035] The base 304 has several movable buckles 306 along its inner circumference, and the movable buckles 306 are connected to the release blocks 307 on the outer circumference via connecting shafts.

[0036] When in use, the central column 301 rotates, causing the steel cable 2 to wind onto the tightening shaft 303. After tightening, the tightening shaft fixing block 305 is locked in the movable buckle 306. When it is necessary to release the steel cable 2, simply press down the release block 307.

[0037] To further optimize the above technical solution, the connection surface between the steel cable fixing block 200 and the steel cable 2 is a curved surface, and the curvature of the curved surface is consistent with the inner curvature of the tightening shaft 303.

[0040] To further optimize the above technical solution, the movable buckle 306 on the base 304 is provided with a spring device inside, and the bottom of the base 304 is provided with a rubber pad layer.

[0041] The movable latch 306 and the release latch 307 form a linkage structure. When the tightening shaft 303 rotates, the movable latch 306 springs back through the spring device. When the tightening shaft 303 is stationary, the movable latch 306 is in the protruding state, which can stop the tightening shaft 303 from rotating.

[0042] The rubber pad increases the friction between the base 304 and the support plate 1, making the base 304 fit the support plate 1 more firmly.

[0043] To further optimize the above technical solution, the locking device 3 has an overall "I" shaped outline structure.

[0044] The cover 300 and the base 304 together form a retaining edge, which allows the steel cable 2 to be better wound around the tightening shaft 303.

[0045] To further optimize the above technical solution, the central column 301 is provided with a through hole 302, and the top of the central column 301 is provided with an internal hexagonal recess.

[0046] In use, cover the support plate 1 with the area that needs reinforcement, place the locking device 3 in the center of the support plate 1, remove the steel cable fixing block 200, and let the steel cable 2 pass through the through holes in several central columns 301 (preferably four sets for square structures). Finally, thread the steel cable fixing block 200 back on, rotate to open the cover 300 on the locking device 3, and insert the steel cable fixing blocks 200 at both ends of the steel cable 2 into the notches on the tightening shaft 303. Rotate to close the cover 300 on the locking device 3, and use an electric drill to rotate the tightening shaft 303 through the hexagonal recess at the top of the central column 301. The steel cable 2 will tighten accordingly, and the excess part will be wrapped around the tightening shaft 303. After the steel cable 2 is tightened, the tightening shaft fixing block 305 will be locked in the movable buckle 306. When it is necessary to release the steel cable 2, press down the release block 307.
