Description

Technical Field

[0001] This utility model relates to the field of scaffolding component technology, and in particular to a special fastener for scaffolding steel mesh protective panels. Background Technology

[0002] During construction, scaffolding must be equipped with steel plate safety netting to ensure construction safety. The safety netting needs to be fixed to the main body of the scaffolding using special connectors. Traditional methods often use welding or bolts for fastening, which have problems such as low assembly and disassembly efficiency and poor adaptability.

[0003] In the prior art, Chinese utility model patent application number 202420164572.2 discloses a novel buckle for connecting components of protective netting on external scaffolding steel plates. This novel buckle for connecting components of protective netting on external scaffolding steel plates includes a connecting pipe and a clamping plate welded to one end of the connecting pipe. The clamping plate has an integrally formed bent portion at the end away from the connecting pipe. There are two bent portions, which are arranged symmetrically and crosswise. The clamping plate has a T-shaped groove, and an abutment plate is inserted into the T-shaped groove. The applicant of this utility model believes that the buckle has a simple structure, is easy to manufacture, convenient to install, and has high safety.

[0004] However, the optimization of this technical solution focuses on the connection end of the protective netting; the scaffolding connection end still relies entirely on external fasteners, failing to achieve rapid overall installation. The connecting pipes are vertically installed on the scaffolding fittings and fixed with clamps. The key issue is that the main scaffolding structure is usually also a transverse tubular component; when the two are arranged perpendicularly, conventional clamp structures are difficult to effectively lock and restrain them. This structure exhibits significant stress concentration points and a lack of lateral stability, making it highly susceptible to displacement or even loosening under load, posing a clear construction safety hazard. Utility Model Content

[0005] The technical problem to be solved by this utility model is that existing scaffolding protective plate fasteners are prone to displacement or loosening under load.

[0006] To achieve the above objectives, according to one aspect of the utility model, a special fastener for scaffolding steel mesh protective panels is provided, comprising: a protective panel connecting part for connecting to a protective panel, wherein two bent parts are integrally formed on one side of the protective panel connecting part, and the two bent parts are respectively connected to two protective panels; a scaffold connecting part disposed on the side of the protective panel connecting part away from the bent parts; and an abutment plate movably disposed on the protective panel connecting part for abutting against the inner side of the protective panel; wherein the scaffold connecting part includes a clamping unit and a locking unit, the clamping unit clamping the circumference of the scaffolding steel pipe, and the locking unit adjusting the clamping gap of the clamping unit to form a lock.

[0007] As a preferred embodiment of the above technical solution, the contact plate engages with the connecting portion of the protective plate through a limiting slot formed on the connecting portion of the protective plate; the cross-sectional length of the contact plate gradually decreases from top to bottom, and the length of the limiting slot is greater than the minimum cross-sectional length of the lower end of the contact plate, while the length of the limiting slot is less than the maximum cross-sectional length of the upper end of the contact plate.

[0008] As a preferred embodiment of the above technical solution, the thickness of the contact plate is less than or equal to the width of the limiting slot; at least one side of the lower end of the contact plate is provided with a limiting protrusion to prevent the contact plate from being pulled upward from the limiting slot.

[0009] As a preferred embodiment of the above technical solution, the side of the contact plate facing the bend and the side away from the bend are respectively a vertical surface and an inclined surface, and an inwardly opening is provided on the inclined surface.

[0010] As a preferred embodiment of the above technical solution, the clearance opening allows the contact plate to form a rotating part at that position; a pivot hole is provided on the limiting slot, and the rotating part can be adapted to be accommodated in the pivot hole, so that when the rotating part is in the pivot hole, the contact plate can rotate around the pivot hole, thereby switching the orientation of the vertical surface and the inclined surface.

[0011] As a preferred embodiment of the above technical solution, the clamping unit includes a lower clamping plate and an upper clamping plate; the lower clamping plate is integrally formed with the connecting part of the protective plate, and a limiting insertion hole is provided on the side of the lower clamping plate away from the bending part; one end of the upper clamping plate is inserted into the limiting insertion hole and is movably connected to the lower clamping plate; a lower locking hole and an upper locking hole are respectively provided on the lower clamping plate and the upper clamping plate, and the locking unit passes through the lower locking hole and the upper locking hole to achieve locking.

[0012] As a preferred embodiment of the above technical solution, the limiting socket includes a connected limiting area and an unlocking area, wherein the width of the limiting area is greater than the width of the unlocking area; one end of the upper clamping plate inserted into the limiting socket is provided with a limiting boss, and the cooperation between the limiting boss and the limiting area forms a limiting effect on the upper clamping plate; rotating the upper clamping plate causes the limiting boss to rotate and partially enter the unlocking area, thereby making the upper clamping plate unlockable.

[0013] As a preferred embodiment of the above technical solution, the upper clamping plate is provided with an upwardly curved upper arc-shaped portion, and the lower clamping plate is provided with a downwardly curved lower arc-shaped portion.

[0014] As a preferred embodiment of the above technical solution, the lower locking hole is an oblong hole, and the upper locking hole is a notched hole.

[0015] In summary, this utility model has the following advantages:

[0016] 1. This utility model connects the protective plate through an integrated bending part of the protective plate connection part, and the clamping unit of the scaffold connection part covers the circumference of the steel pipe and is locked by adjusting the clamping gap through the locking unit. At the same time, the abutment plate can be moved to rest against the inner side of the protective plate. This structure realizes the quick installation and disassembly of the fasteners, improves the construction efficiency, and enhances the stability through the clamping and locking mechanism, effectively preventing the steel pipe from shifting or loosening, and ensuring construction safety.

[0017] 2. The trapezoidal structure and limiting slot design of the contact plate ensure that the contact plate is locked in place during descent, providing stable support and preventing the protective plate from loosening. At the same time, the rotating part and the pivot hole cooperate to allow the contact plate to rotate and switch between vertical and inclined planes, improving the adaptability of the fastener to different installation scenarios and the efficiency of on-site adjustment.

[0018] 3. The limiting insertion hole and limiting boss of the clamping unit cooperate to achieve the pre-fixation of the upper clamping plate. After the operator inserts the upper clamping plate, he can lock it by rotating it to form a stable state, which facilitates the subsequent insertion of steel pipe and reduces the risk of loosening during the installation process. At the same time, the arc-shaped clamping surfaces of the upper and lower clamping plates match the curvature of the steel pipe, increasing the contact area and improving the anti-slip performance and overall reliability.

[0019] Further or other beneficial effects will be discussed in the embodiments. Attached Figure Description

[0026] The present invention will be further explained below with reference to the embodiments: Example

[0027] A special fastener for scaffolding steel mesh protective panels, as shown in the reference. Figure 1 and Figure 2 It includes a protective plate connecting part 1, a scaffold connecting part 2, and an abutment plate 3. The protective plate connecting part 1 has two bending parts 11 on one side. One bending part 11 bends upward to connect to the steel mesh protective plate located above in the space, and the other bending part 11 bends downward to connect to the steel mesh protective plate located below in the space. The two bending parts 11 and the protective plate connecting part 1 are manufactured using an integral molding process.

[0028] A scaffolding connection part 2 is provided on the side of the protective plate connection part 1 away from the bending part 11. The scaffolding connection part 2 includes a clamping unit 4 and a locking unit 5. The clamping unit 4 is used to cover the outer circumferential surface of the scaffolding steel pipe, and the locking unit 5 achieves locking by changing the gap of the clamping unit 4. An abutment plate 3 is movably installed on the surface of the protective plate connection part 1, and its function is to provide support against the inner side of the protective plate.

[0029] The clamping unit 4 consists of a lower clamping plate 42 and an upper clamping plate 41. The lower clamping plate 42 is integrally cast with the protective plate connecting part 1, and a limiting insertion hole 421 is provided on the side away from the bending part 11. One end of the upper clamping plate 41 is inserted into the limiting insertion hole 421 to form a movable connection with the lower clamping plate 42. At the same time, the other end of the upper clamping plate 41 is provided with an upper locking hole, which is an inwardly opened notch hole 401. The lower clamping plate 42 is provided with a lower locking hole at the end away from the limiting insertion hole 421, which is an oblong hole 402; this facilitates flexible adjustment of the locking components. The locking unit 5 includes a locking bolt 51 and a locking nut 52. The locking bolt 51 passes through the lower locking hole and the upper locking hole from bottom to top and is threadedly engaged with the locking nut 52 located above the upper clamping plate 41. With continuous tightening, the upper clamping plate 41 and the lower clamping plate 42 continuously clamp the steel pipe on the scaffold, thereby fixing the entire fastener relative to the scaffold. In addition, in this embodiment, the upper clamping plate 41 and the lower clamping plate 42 are respectively provided with upwardly curved and downwardly curved arc-shaped clamping surfaces. This contour design matches the curvature of the scaffold steel pipe, enhancing the surface fit with the curved surface of the steel pipe, thereby increasing the contact area and improving the anti-slip performance. An integrated lever 521 is provided at the top of the bolt, allowing the operator to complete the tightening operation without additional tools.

[0030] Reference Figure 3 Previous Figure 1 and Figure 2 The upper clamping plate 41, which is inserted into the fiber optic insertion hole, includes a limiting area 4211 and an unlocking area 4212 that are connected to each other. The width of the limiting area 4211 is greater than the width of the unlocking area 4212. The upper clamping plate 41 is provided with a limiting boss 411 at one end. The cooperation between the limiting boss 411 and the limiting area 4211 forms a limiting on the upper clamping plate 41. The cross-sectional profile of the limiting boss 411 is greater than the cross-sectional profile of the limiting area 4211. The thickness of the limiting boss 411 is less than the width of the unlocking area 4212. Therefore, rotating the upper clamping plate 41 causes the limiting boss 411 to rotate so that part of it enters the unlocking area 4212. The total length of the limiting area 4211 and the unlocking area 4212 is greater than or equal to the width of the limiting boss 411. In this state, the limiting boss 411 can be axially pulled out from the limiting insertion hole 421, which facilitates storage.

[0031] During installation, the operator first holds the upper clamping plate 41 and vertically inserts the end with the limiting boss 411 into the limiting socket 421. Next, the operator grasps the main body of the upper clamping plate 41 and precisely rotates it. This action moves the limiting boss 411 from the unlocking area 4212 into the limiting area 4211, which has a smaller cross-sectional area than the limiting boss 411. The limiting boss 411 is mechanically blocked by the wall of the limiting area 4211, restricting its axial movement and forming a stable "pre-fixed" state. At this point, the upper clamping plate 41 is reliably pre-fixed to the lower clamping plate 42 and will not loosen on its own without human intervention. Then, the scaffolding steel pipe to be installed is inserted into the clamping space formed by the upper clamping plate 41 and the corresponding lower clamping plate 42. At this moment, under the action of the pre-fixing structure, the steel pipe is initially clamped in the predetermined position. Finally, the fasteners are tightened to complete the positional limitation of the scaffolding steel pipe.

[0032] The contact plate 3 engages with the protective plate connecting part 1 via a limiting slot 21 formed on the protective plate connecting part 1. Specifically, the cross-sectional length of the contact plate gradually decreases from bottom to top, and the length of the limiting slot 21 is greater than the minimum cross-sectional length of the lower end of the contact plate 3 but less than the maximum cross-sectional length of the upper end of the contact plate 3. In other words, the contact plate has an overall trapezoidal structure. When the contact plate 3 is lowered to a certain position, the narrow part of its length that is greater than the limiting slot 21 is held in place by the two walls of the slot, bearing the inward force transmitted from the protective plate and preventing the protective plate from loosening. At this time, it provides stable support. When it is necessary to disassemble or significantly adjust the protective plate, the contact plate 3 can be lifted. When it is lifted to a sufficient height, the width of the contact plate 3 is less than the length of the limiting slot 21, allowing it to be easily rotated or tilted out, completely clearing space for quick disassembly or replacement of the protective plate. This design greatly simplifies the disassembly and assembly process of the protective plate.

[0033] To ensure the absolute safety of the contact plate 3 when it is in the load-bearing position and to prevent it from accidentally jumping out of the slot under vibration or impact, a limiting protrusion 31 is designed on at least one side of the lower end of the contact plate 3. When the contact plate 3 descends to a certain position, the limiting protrusion 31 is precisely locked under the lower edge of the limiting slot 21. Its beneficial effect is very direct: it forms a reliable physical barrier, completely eliminating the risk that the contact plate 3 will be pushed upwards due to insufficient friction in the slot when subjected to the pressure of the protective plate, ensuring long-term reliability of operation. At the same time, the thickness of the contact plate 3 is less than or equal to the width of the limiting slot 21, ensuring smooth and unobstructed vertical movement.

[0034] The side of the contact plate 3 facing the bend 11 and the side away from the bend 11 are a vertical surface 32 and an inclined surface 33, respectively.

[0035] To further improve ease of operation, a clearance 34 is machined inward on the inclined surface 33. The presence of this clearance 34 creates a rotating portion for the contact plate 3 in this area. A pivot hole 211, with a matching shape, is precisely provided at the position corresponding to the limiting slot 21. (Refer to...) Figure 3 and Figure 4 When it is necessary to change the state of the contact plate 3, the installer can lift the contact plate 3, align its rotating part, and insert it into the pivot hole 211. At this time, the contact plate 3 can easily rotate around the axis of the pivot hole 211. The significant benefit is that the operator can interchange the positions of the originally outward-facing vertical surface 32 and the inward-facing inclined surface 33 with just a simple rotation. This means that the load-bearing direction of the contact plate 3 can be quickly switched according to the actual installation needs without completely removing the contact plate 3, improving the adaptability of the fastener to different installation scenarios and the efficiency of on-site adjustment.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
