Description

Technical Field

[0001] The invention relates to the technical field of building template construction, in particular to a building template fastening device. Background Art

[0002] A building formwork is a temporary support structure, manufactured according to design requirements, that helps concrete structures and components form to the specified positions and dimensions, maintain their correct position, and withstand the formwork's own weight and external loads. The purpose of formwork engineering is to ensure the quality and safety of concrete projects, accelerate construction progress, and reduce costs.

[0003] The building formwork used in cast-in-place concrete construction primarily consists of a panel and a supporting structure. The panel is the load-bearing slab that directly contacts the newly poured concrete. The supporting structure is a temporary structure that supports the panel, concrete, and construction loads, ensuring the building formwork is securely assembled and protected from deformation and damage. Fasteners connect the panel and supporting structure to form a single unit.

[0004] Since fasteners are generally fixed to the outside of the panel in a combined manner and have multiple parts, the efficiency is low and the stability is insufficient during installation and disassembly. Therefore, we propose a fastening device for construction templates. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a construction template fastening device that is easy to install and disassemble and has good stability, which can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a construction template fastening device, comprising a long fastening rod, a wide fastening rod, a length limiting member, and a width limiting member;

[0007] Long fastening rods: There are two long fastening rods that are relatively parallel and have a socket in the middle section and a sliding groove on the side of the long fastening rods;

[0008] Wide fastening rods: There are two wide fastening rods that are arranged in parallel with each other, and the wide fastening rods pass through the sliding grooves of the two long fastening rods in a direction perpendicular to the long fastening rods;

[0009] Length limiting member: comprising two telescopic rods hinged at adjacent ends, the other ends of the two telescopic rods being hinged to the ends of the wide fastening rods respectively, and the hinged portions of the two telescopic rods corresponding to the sockets;

[0010] Width limiting pieces: set at both ends of each wide fastening rod and supported on the side faces of the long fastening rod facing outwards.

[0011] Furthermore, the included angle between the two telescopic rods is less than 180°, and an anti-slip hook is fixed to one end of the hinged connection between the two telescopic rods. During the deployment of adjacent fastening devices, the hinged ends of the two telescopic rods of the upper fastening device are inserted into the sockets of the lower fastening device. The anti-slip hook prevents them from sliding out, and the upper and lower ends are restrained, thereby improving the stability of the panel support.

[0012] Furthermore, the telescopic rod comprises a sleeve rod, an inner rod, and a locking bolt. The inner rod is slidably mounted within the sleeve rod's inner cavity. The locking bolt is threadedly connected to a threaded hole in the sleeve rod's side, with the inner end of the locking bolt pressing against the surface of the inner rod. The length limiter is connected by two telescopic rods, and the angle between them can be controlled to adjust the spacing between adjacent fastening devices to meet different usage requirements.

[0013] Furthermore, both ends of the wide tightening rod are equidistantly provided with vertically penetrating auxiliary grooves, wherein wedges are provided in the auxiliary grooves to limit the position of the long tightening rod at the end of the wide tightening rod through the wedges.

[0014] Furthermore, the wedge is triangular in shape and abuts against the side of the long fastening rod when inserted into the auxiliary slot. Before using the width limiter, the wedge can be used to squeeze the long fastening rod to move it to the appropriate width of the panel, and then the width limiter can be locked, which saves effort during operation.

[0015] Furthermore, the width limiting member includes a clamping block, a nut seat, and a support bolt. The clamping block is clamped onto the end of the wide fastening rod, the nut seat is fixed to the clamping block, and the support bolt is threadedly connected to the threaded hole of the nut seat. The end of the support bolt is supported on the outward side of the long fastening rod. The width limiting member is squeezed on the outside of the two long fastening rods to control the spacing between the long fastening rods.

[0016] Furthermore, the clamping block is generally U-shaped, with its opening parallel to the length of the long fastening rod. One end of the clamping block passes through a slot in the long fastening rod and latches onto the end of the long fastening rod. After the support bolt is rotated a certain distance, the entire width limiter can be removed in a direction perpendicular to the support bolt, making installation and removal efficient.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the building construction template fastening device has the following advantages:

[0018] 1. This construction formwork fastening device defines an adjustable rectangular space through two long fastening rods and two wide fastening rods, fastens and locks the construction formwork panel from the outside, is easy to install and disassemble, and has good stability.

[0019] 2. During the installation of adjacent fastening devices, the hinged ends of the two telescopic rods of the upper fastening device are inserted into the sockets of the lower fastening device to prevent them from unhooking and sliding out. The upper and lower rods are mutually limited, which can improve the stability of the panel support.

[0020] 3. The length limiter is connected by two telescopic rods, and the size of the included angle can be controlled to adjust the distance between adjacent fastening devices to meet different usage requirements;

[0021] 4. Before using the width limiter, you can first use a wedge to squeeze the long fastening rod so that the long fastening rod fits the panel and moves to a position of appropriate width, and then lock the width limiter, which will save effort during operation.
