Description

Technical Field

[0001] The utility model relates to the technical field of building formwork locking, and more specifically, to a formwork locking clip. Background Art

[0002] Traditional building formwork installation uses bolt connection or step-by-step tightening or various other special fixtures for connection. Bolt connection has low installation efficiency and requires two wrenches for operation, which is inconvenient. Therefore, there is an urgent need for a tool that is convenient and fast to disassemble and assemble in the formwork market.

[0003] A prior patent discloses a formwork locking device. The formwork locking device includes a fixed part and a locking rod. The fixed part is a straight rod with an elbow at one end. The locking rod is provided with a locking hole, and the locking rod is sleeved on the straight rod through the locking hole. Moreover, the height of the locking hole is slightly greater than the height of the straight rod. The formwork can be fixed by using the self-locking principle through the elbow and the locking rod. When disassembling, only the upper end of the locking rod needs to be knocked. It is convenient to use and can be recycled. Moreover, the bolts used for fixation are omitted, which not only reduces the process of machining the locking device and saves raw materials, but also improves the service life of the formwork locking device. However, this formwork locking device does not have an anti-loosening structure and is prone to loosening after the formwork is locked, with poor reliability. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiency of poor reliability of the existing formwork locking, and provide a formwork locking clip with high reliability.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] Provide a formwork locking clip, including a fixed seat, a movable buckle plate, and a locking strip. The movable buckle plate is inserted into the fixed seat, and the locking strip is located below the fixed seat and is inserted into the end of the movable buckle plate passing through the fixed seat. A first buckling part is provided at the end of the fixed seat away from the locking strip, and a second buckling part is provided at the end of the movable buckle plate away from the locking strip. A formwork accommodating space is formed between the first buckling part and the second buckling part. The size of the accommodating space can be adjusted by adjusting the insertion position of the movable buckle plate and the fixed seat.

[0007] The template locking clip of the present utility model, as a dedicated template fixture, makes the clamping of the template more convenient to operate and simpler. The template locking clip of the present utility model uses the template locking for wind prevention and the docking between templates. The fixed seat serves as a fixed bracket, the movable buckle plate serves as a movable upper hook clamping plate, and the lock bar serves as a movable locking strip-shaped component. The three components are connected in series by sequential insertion to form an integral body. By placing the template in the accommodation space formed between the first buckling portion and the second buckling portion of the movable buckle plate and the fixed seat, and then knocking the lock bar to make the connection between the lock bar and the movable buckle plate firm, at the same time, the movable buckle plate and the fixed seat lock the template, and multiple components pull each other to realize the locking function of the template locking clip. The template locking clip of the present utility model aims to provide a functional connection function, with functions such as quick disassembly and assembly, convenient combination, stable structure, safety and reliability, etc., and can realize the quick docking and clamping during the assembly of the floor construction template, and can meet the requirements of various construction engineering occasions.

[0008] Further, the lock bar is of a wedge-shaped structure. The wedge-shaped structure is a structure with a small end and a large end. When using the lock bar to lock the movable buckle plate, knocking from the small side of the lock bar to the large side of the lock bar can lock the movable buckle plate, and can also realize the contraction of the template accommodation space of the first buckling portion and the second buckling portion between the movable buckle plate and the fixed seat, thereby realizing the locking of the template.

[0009] Further, it further includes an anti-disengagement nail, and the anti-disengagement nail is inserted into the small end of the wedge-shaped structure of the lock bar. Preferably, the anti-disengagement nail can be a rivet, and the anchor nail is a conventional semi-circular head rivet, and the cylindrical structure of the anchor nail is inserted into the lock bar. The anti-disengagement nail, as a limiting member of the lock bar, can prevent the lock bar from disengaging from the movable buckle plate, thereby ensuring the locking function of the target.

[0010] Further, the first buckling portion and the second buckling portion are hook-shaped structures arranged oppositely. The hook-shaped first buckling portion and second buckling portion are helpful for clamping or abutting and locking the template placed between the first buckling portion and the second buckling portion.

[0011] Further, the fixed seat includes a support main body and a buckling main body. The support main body is of a U-shaped structure. The buckling main body is located in the U-shaped hollow of the support main body, and one side of the buckling main body is connected to the side part of the support main body, and the other side is a free side. The first buckling portion is located at the top of the buckling main body. The support main body provides an insertion space for the movable buckle plate, making it convenient for the movable buckle plate to be inserted into the fixed seat, while the buckling main body can facilitate the fixed seat and the movable buckle plate to apply force to the template together to lock the template.

[0012] Further, the support body includes a first side, a bottom plate, and a second side that are sequentially connected. The first side is connected to the buckling body, and the second side forms an inclined angle of 45° ± 5° with the bottom plate. The bottom plate is provided with a first through hole, and the movable buckle plate is inserted into the first through hole. The first side, the bottom plate, and the second side are connected to each other to form a U-shaped structure. Preferably, the support body and the buckling body are integrally formed, and the buckling body and the first side form an L shape through bending.

[0013] Further, a limiting step is provided at the top of the first side. The limiting step can limit the template.

[0014] Further, the movable buckle plate includes a straight plate and an inclined plate that are connected to each other. The second buckling portion is installed at the end of the inclined plate away from the straight plate. The straight plate is inserted into the fixed seat, and the locking bar is inserted into the straight plate. A chamfer is provided at the bottom of the straight plate to avoid accidentally injuring construction workers. At the same time, it can also be used to reduce stress concentration and prevent the movable buckle plate from cracking during collision.

[0015] Further, the straight plate is provided with a second through hole, and the locking bar is inserted into the second through hole. Preferably, both the first through hole and the second through hole are square holes.

[0016] Further, a boss is provided at the end of the locking bar away from the anti-disengagement nail. The locking bar can be formed by sheet metal blanking. One side of the locking bar is a straight surface, and the other side is an inclined surface. The boss has a limiting function on the one hand, and provides multiple guarantees for the locking bar on the basis of the wedge-shaped structure to prevent the locking bar from disengaging from the large end of the movable buckle plate; on the other hand, the boss provides a knocking part for easy knocking, so that the locking bar can be locked with the movable buckle plate.

[0017] Further, a third through hole is provided at the end of the locking bar away from the boss. The anti-disengagement nail is inserted into the third through hole. An arc is provided at the small end of the wedge-shaped structure of the locking bar. The center of the third through hole coincides with the center of the arc. The anti-disengagement nail is installed on the locking bar, which can prevent the inclined locking bar from disengaging from the movable buckle plate, thereby ensuring the locking function of the template.

[0018] The working principle of the present invention: The first buckling portion of the fixed seat and the second buckling portion of the movable buckle plate are used to tighten the two sides of the template inward. After one end of the movable buckle plate passes through the first through hole of the bottom plate of the fixed seat, the locking bar is passed through the second through hole on the straight plate of the movable buckle plate from the small end, and then the locking bar is knocked from the boss. When the locking bar moves from the large end to the small end, the inclined surface of the locking bar presses on the second through hole of the movable buckle plate to be tensioned. The straight surface opposite to the inclined surface of the locking bar is attached to the bottom surface of the fixed seat. The use function of the template locking clamp is achieved by tightening and loosening through the movement of the locking bar.

[0019] The template locking clip of the present utility model can be made by welding high-carbon steel, with stable structure, convenient disassembly and assembly, not easy to deform, and can be reused.
