Description

Technical Field

[0001] This utility model relates to the field of civil engineering, and in particular to a novel formwork fastening device for civil engineering construction. Background Technology

[0002] An existing patent (publication number: CN217106166U) proposes a formwork fastening device for building construction, including a vertical formwork, a first reinforcing plate, an L-shaped fixing plate, a second reinforcing plate, a first reinforcing plate baffle, a second reinforcing plate baffle, an upper positioning column, an upper U-shaped pull plate, and a rectangular forming base plate. The lower surface of the vertical formwork is in contact with the rectangular forming base plate, and adjacent vertical formworks are in contact with each other. The first reinforcing plate baffle connects to the vertical formwork, the right side of the first reinforcing plate is in contact with the vertical formwork, and the upper side of the first reinforcing plate is in contact with the first reinforcing plate baffle. The first reinforcing plates are symmetrically arranged on the sides of the vertical formwork, and the symmetrical first reinforcing plates are in contact with each other. However, the structure of the "L-shaped fixing plate" in this device is relatively fixed, and it is impossible to flexibly change its fastening size according to the actual size of the construction formwork. Its adaptability is not ideal, and it has drawbacks. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a novel formwork fastening device for civil engineering construction. This device ensures stable fastening, prevents formwork displacement during concrete pouring, guarantees the effectiveness of civil engineering construction, and allows for rapid scaling and adjustment of the fastening dimensions between fastening frames according to the actual size of the formwork and fastening requirements. This ensures the strength of the fastening force while improving the efficiency of formwork fastening operations in civil engineering construction.

[0004] The objective of this utility model is achieved through the following technical solution: A novel formwork fastening device for civil engineering construction includes a formwork, a fastening frame, a positioning support rod, a fixing plate, a spring strip, a locking sleeve, and a lever. The formwork is externally connected to the fastening frame. One side of the fastening frame has a positioning support sleeve connected to the formwork, and the other side of the fastening frame has a fastening support sleeve connected to the formwork. The fastening support sleeve has an internal slide rail that adapts to the positioning support sleeve, and the positioning support sleeve slides within the slide rail. The positioning support sleeve has slots on both sides, and the fastening support sleeve has insert plates on both sides that adapt to the slots and connect to the slots. The fastening support sleeve is externally connected to the fixing plate, and the outer end of the fixing plate has a connecting plate. A screw passes through the connecting plate, and both ends of the screw are connected to nuts via threads. The inner end of the fixing plate has a limiting block, and both sides of the fastening support sleeve have blocking through holes. Both sides of the positioning support sleeve have limiting grooves, and the limiting grooves and blocking through holes adapt to the limiting blocks. The limiting blocks pass through the blocking through holes and connect to the limiting grooves.

[0005] The fastening frame of this utility model has an external mounting block, an internal sliding groove that is compatible with a locking sleeve, and the locking sleeve is connected to the sliding groove. The outer end of the locking sleeve has a pressure plate, and the inner end of the locking sleeve is connected to a spring strip. The spring strip is connected to the mounting block. The mounting block has a sliding hole, and the locking sleeve has a lever groove. The lever groove and the sliding hole are compatible with a lever. The lever passes through the sliding hole and is connected to the lever groove. Beneficial effects

[0006] This utility model has four sets of fastening frames that interlock and surround the outside of the template to form a fastening frame, preventing the template from shifting or moving and ensuring the construction effect of civil engineering. At the same time, the fastening size can be quickly adjusted by turning the crank handle to meet the fastening needs of templates of different specifications. It has strong adaptability and flexible structure.

[0007] The positioning support rod of this utility model is positioned and connected to the positioning support sleeve through a thread, and cooperates with the limiting guide of the slide and the fixed buckle plate, so that the support distance between the fastening frames can be quickly adjusted by rotating the crank handle, thereby meeting the fastening requirements of templates of different sizes, ensuring the strength of the fastening force, and being easy to operate, thus improving the efficiency of template fastening operations in civil engineering construction.

[0008] The locking block of this utility model engages with the locking groove of the positioning support rod, and the continuous pressure of the locking sleeve by the spring strip can stably lock the adjusted position of the fastening frame, preventing the formwork from shifting during concrete pouring and improving the stability of the formwork fastening. When the locking sleeve is moved by pressing the pressure plate until the locking block and the locking groove are completely disengaged, the braking fulcrum of the locking sleeve on the positioning support rod disappears. At this time, the fastening size between the fastening frames can be quickly adjusted by turning the crank handle according to the actual size of the formwork and the fastening requirements. The structure is flexible and the operation is convenient.

[0009] This utility model provides a stable and secure fastening mechanism to prevent formwork displacement during concrete pouring, ensuring the effectiveness of civil engineering construction. It also allows for rapid scaling and adjustment of the fastening dimensions between the fastening frames according to the actual size of the formwork and fastening requirements. This ensures strong fastening force while maintaining a flexible and adaptable structure, making it easy to operate and improving the efficiency of formwork fastening operations in civil engineering construction.
