Description

Technical Field

[0001] This utility model relates to the field of construction scaffold reinforcement technology, specifically a construction scaffold reinforcement device. Background Technology

[0002] Construction scaffolding is an important temporary facility used for high-altitude operations during construction, primarily providing workers with a safe operating platform and access. It is typically constructed from steel pipes, fasteners, and scaffold boards, and is flexible and adjustable to adapt to the needs of buildings of varying heights and shapes. Construction scaffolding not only supports the working surface but also handles material transportation and formwork installation, effectively improving construction efficiency. Its design must strictly adhere to safety regulations to ensure load-bearing capacity and stability, preventing collapse accidents.

[0003] Nodes typically rely on right-angle couplers or swivel couplers for locking. As the scaffold structure needs to frequently change its height and planar shape as construction progresses, the reinforcement components must be able to be quickly assembled and disassembled, reused, and maintain geometric stability under bidirectional loads to ensure the safety of personnel and materials. Traditional couplers can only provide point contact locking and their height is not adjustable. When encountering members of different diameters or staggered heights, couplers need to be stacked or sleeves need to be welded on. Assembly and disassembly are time-consuming and can easily produce eccentric gaps, leading to problems such as node slippage and scaffold lateral displacement. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a building construction scaffold reinforcement device, including a semi-circular sleeve one, a bolt one fixedly connected to the left end of the semi-circular sleeve one, a semi-circular sleeve two sleeved on the surface of the bolt one, a nut one threadedly connected to the surface of the bolt one, a connecting rod fixedly connected to the top of the semi-circular sleeve one, a limit block fixedly connected to the top of the connecting rod, a threaded rod fixedly connected to the top of the limit block, an extension sleeve one sleeved on the surface of the threaded rod, a nut two threadedly connected to the surface of the threaded rod, a nut three threadedly connected to the surface of the threaded rod, and an extension rod fixedly connected to the top of the extension sleeve one.

[0005] Using the above technical solution, the first positioning is achieved by using bolt one and nut one to hold the two semi-circular sleeves at any height of the upright; then, the extension sleeve one is slid along the threaded rod to the corresponding position of the horizontal or diagonal bar, and the second locking can be achieved by simply tightening nut two and nut three.

[0006] As a further improvement to the above scheme, the number of bolts is set to four, and the four bolts are evenly distributed symmetrically on the left end surface of the semicircular sleeve in pairs. The semicircular sleeve is located between the nut and the semicircular sleeve.

[0007] With the above technical solution, the four bolts are arranged symmetrically in the center, so that the clamping force of the semi-circular ferrule one and the semi-circular ferrule two is evenly distributed on the circumference of the pole, avoiding stress concentration at a single point and ensuring that there will be no skewing or slippage after the node is tightened.

[0008] As a further improvement to the above solution, the connecting rod passes through the first extension sleeve, which is located between the second nut and the third nut.

[0009] Through the above technical solution, the connecting rod passes through the extension sleeve and is clamped by the second and third nuts, forming a rigid cantilever beam load-bearing structure, which enables the extension sleeve to have self-bending ability when subjected to lateral load and reduces swaying.

[0010] As a further improvement to the above solution, the extension sleeve one is fitted with a bolt two inside, and the right end of the bolt two is fixedly connected to the extension sleeve two.

[0011] By using the above technical solution, by attaching bolt 2 inside the extension sleeve 1 and connecting extension sleeve 2 outside, a double-layer clamp can be formed at the same node, which further increases the clamping depth of the horizontal or diagonal bar and enhances the node's resistance to pull-out.

[0012] As a further improvement to the above scheme, the first extension sleeve and the second extension sleeve are concentric, and the number of the second bolts is set to four, with the four second bolts arranged in pairs and symmetrically distributed on the left end surface of the second extension sleeve.

[0013] Through the above technical solution, the first extension sleeve and the second extension sleeve are concentric, and the four bolts are also arranged symmetrically in the center, ensuring that the clamping force of the double-layer clamp is evenly superimposed along the circumference, and avoiding the additional bending moment from causing local deformation of the rod.

[0014] As a further improvement to the above solution, the bottom of the semi-circular sleeve is fixedly connected to a base, and the top of the base is provided with an installation hole.

[0015] Through the above technical solution, a base with mounting holes is added to the bottom of the semi-circular clamp, which can be connected to the floor or foundation through fasteners while holding the upright, thus expanding the node reinforcement into an integrated anchoring of the upright and foundation and improving the bottom stability.

[0016] As a further improvement to the above solution, two bases are provided, and the two bases are respectively fixedly connected to the bottom of the semi-circular sleeve one and the semi-circular sleeve two.

[0017] Through the above technical solution, the two bases are fixed to the bottom of the semi-circular sleeve one and the semi-circular sleeve two respectively, forming a double-support ground structure, so that the weight of the reinforcement device itself and the construction load are evenly transferred to the foundation through the two points, avoiding the failure of one side of the base due to overload.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model achieves the first layer of locking by setting up a semi-circular retaining sleeve 1, a bolt 1, a nut 1, and a semi-circular retaining sleeve 2. After the two semi-circular retaining sleeves are tightly held against the outer wall of the construction frame upright, the nut 1 is tightened to achieve the first layer of locking. Then, using the adjustable height pair composed of the connecting rod, threaded rod, extension retaining sleeve 1, and nut 2 / nut 3, the extension retaining sleeve 1 is quickly slid to the corresponding height of the construction frame horizontal or diagonal bar and locked again to complete the second layer of locking, thus fixing the surface of the construction frame.

[0020] This utility model sets up an extension sleeve one, a bolt two, an extension sleeve two and an extension rod. After the node is locked, the extension sleeve two is spliced ​​with the extension sleeve one by the bolt two to form an extended clamp that passes through the node; the extension rod continues to extend upward or downward along the axial direction of the rod and is superimposed and locked with the adjacent segment.

Then, the extension sleeve 1 8 is fitted onto the surface of the threaded rod 7 and fitted onto the connection position of the construction frame. Then, nut 3 10 is rotated so that the top of nut 3 10 contacts the bottom of extension sleeve 1 8. Then, nut 2 9 is rotated again to lock extension sleeve 1 8 in the position between nut 2 9 and nut 3 10, thus fixing the entire construction frame. Through extension rod 13, it can be extended according to the overall height of the construction frame to carry out surface reinforcement work on the entire construction frame.

[0029] There are four bolts 1-2. The four bolts 1-2 are arranged in pairs, and the semicircular ferrule 1 is symmetrically and evenly distributed on the left end surface. The semicircular ferrule 2-3 is located between the nut 1-4 and the semicircular ferrule 1.

The bolt 11 is fitted inside the extension sleeve 8 and fixed to the extension sleeve 12 with a nut, which increases the strength of the construction frame at the pipe connection position.
