Description

Technical Field

[0001] This utility model relates to the field of steel scaffolding platforms, specifically a quick-hook scaffolding platform erection structure for construction scaffolding. Background Technology

[0002] Steel scaffolding planks are a type of construction equipment widely used in fields such as construction, shipbuilding, and petrochemicals. They are primarily used to erect scaffolding working platforms. Made of hot-dip galvanized steel, they are fire-resistant, slip-resistant, and corrosion-resistant. The perforated surface effectively drains water and prevents sand accumulation. Compared to traditional bamboo or wooden planks, steel planks have a stronger load-bearing capacity, are lighter, and easier to transport.

[0003] Currently, steel scaffolding is installed by hooking the steel scaffolding's horizontal bars via hooks on both sides, enabling quick installation. However, a problem exists in practice: the hooks on both sides are mostly welded, which creates an issue with the compatibility of installing the steel scaffolding and disassembling the hooks. Therefore, the inventor urgently needs to design an installation and disassembly mechanism for the steel scaffolding and its hooks to improve the compatibility and convenience of installation. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a quick hook erection platform structure for construction scaffolding, so as to solve the technical problems of poor installation compatibility and inconvenient disassembly caused by welding and fixing steel platform and hook.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick hook erection platform structure for construction scaffolding, comprising a platform body, wherein connecting plates are bolted to both sides of the platform body, and hooks are welded to the outer side of the connecting plates.

[0006] By adopting the above technical solution, the split structure allows construction workers to quickly select and install hook connection components of the appropriate size according to the specific spacing or specifications of the scaffold crossbars on site, which greatly improves the adaptability of the treads to different scaffolding systems. At the same time, the bolt connection method allows the treads to be disassembled into flat parts during storage and transportation, which significantly saves space and reduces logistics costs.

[0007] Furthermore, the connecting plate includes a fixing plate, and side plates are bent on both sides of the fixing plate. The surfaces of the fixing plate and the side plates are respectively provided with a first through hole and a second through hole. The bolt passes through the first through hole, the second through hole, and the pedal body for assembling and fixing the connecting plate.

[0008] By adopting the above technical solution, this U-shaped or trough-shaped structure design with side plates can significantly enhance the structural rigidity and bending resistance of the connecting plate itself compared to a single flat plate, making it less prone to deformation when bearing the load transmitted by the pedal, thus ensuring the long-term stability of the connection.

[0009] Furthermore, the fixing plate and the side plate are bent perpendicularly, and a bending plate is bent perpendicularly on the other side of the fixing plate. The side plate and the bending plate are perpendicularly arranged and welded together.

[0010] By adopting the above technical solution, the connecting plate is finally formed into a three-dimensional frame structure with high torsional stiffness. This structure can effectively resist the torque and off-center load that may be generated in various directions during the use of the pedal, prevent the connecting parts from twisting or loosening, and provide an extremely stable mounting base for the hook.

[0011] Furthermore, the bent plate is welded and fixed to two sets of hooks, the hooks being in a "U" shape.

[0012] By adopting the above technical solution, the "U" hook has a larger contact area and better fit with the circular crossbar of the scaffold compared to the J hook or other forms. This surface contact method can significantly reduce the pressure at the contact point, reduce wear on the crossbar coating, and provide more stable suspension support, thereby reducing the risk of lateral slippage of the treads under lateral force.

[0013] Furthermore, both the connecting plate and the hook are made of Q235B carbon structural steel.

[0014] By adopting the above technical solution, Q235B steel, a widely used material in the construction industry, has a yield strength of 235MPa and a good combination of strength, plasticity and toughness. It can meet the mechanical performance requirements of scaffolding boards under construction live loads and dynamic loads, ensuring that the components will not yield or brittle fracture under normal use.

[0015] Furthermore, the surface of the pedal body is arrayed with several through holes.

[0016] By adopting the above technical solution, when workers are working in wet and slippery weather, the water or mud on the soles of their shoes and the surface of the pedals can easily cause them to slip. These holes can drain liquids and debris in time, increase the actual contact area and friction between the soles of their shoes and the pedals, and act like countless tiny drainage channels and anti-slip teeth, which greatly reduces the risk of workers slipping and falling, and fundamentally improves the safety of working at heights.

[0017] In summary, the present invention has the following main advantages: 1. This utility model adopts a split structure, in which the hook and the connecting plate are welded into an independent unit and then connected to the main body of the pedal by bolts. This structure allows the hook component to be separated from the main body of the pedal, which is convenient for transportation and storage. At the same time, when the hook is damaged, the connecting plate component can be replaced separately without scrapping the entire pedal, which reduces maintenance costs and improves the adaptability to different scaffolding specifications. 2. This utility model uses connecting plates, which are composed of a fixed plate, a side plate, and a bent plate to form a three-dimensional frame. The connecting plates are connected to the pedal body by bolts, which significantly enhances the node rigidity and load distribution capacity. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] In this embodiment: A quick-hook scaffolding platform erection structure for construction, such as... Figure 1-5As shown, the device includes a pedal body 4, with connecting plates 2 attached to both sides of the pedal body 4 via bolts 3. Hooks 1 are welded to the outer side of the connecting plates 2. This split structure allows construction workers to quickly select and install hook connection components of the appropriate size according to the specific spacing or specifications of the scaffold crossbars on site, greatly improving the adaptability of the pedal to different scaffolding systems. At the same time, the bolt connection method allows the pedal to be disassembled into flat parts during storage and transportation, significantly saving space and reducing logistics costs. During the use and maintenance phase, if the hooks are damaged due to collision or excessive wear, it is not necessary to replace the entire expensive pedal body; only the lower-cost connecting plate 2 component needs to be replaced, greatly extending the service life of the pedal body and reducing the overall cost of use, demonstrating good economic and environmental benefits.

[0022] See Figure 3 The connecting plate 2 includes a fixing plate 201, with side plates 203 bent on both sides. The surfaces of the fixing plate 201 and the side plates 203 are respectively provided with a first through hole 204 and a second through hole 205. Bolts 3 pass through the first through hole 204, the second through hole 205, and the pedal body 4 for assembling and fixing the connecting plate 2. This U-shaped or groove-shaped structural design with side plates 203 can significantly enhance the structural rigidity and bending resistance of the connecting plate 2 itself compared to a single flat plate, making it less prone to deformation when bearing the load transmitted by the pedal, thus ensuring the long-term stability of the connection. At the same time, by having bolts 3 pass through the first through hole 204 on the fixing plate 201, the second through hole 205 on the side plate 203, and the pedal body 4 in sequence, a robust clamping connection node is formed. This multi-point, double-shear connection method can more effectively distribute the load and reduce the shear stress of the bolts compared to a single-point connection, preventing the risk of loosening of the connection or tearing of the hole wall of the pedal body 4 due to stress concentration.

[0023] See Figure 3 The fixed plate 201 and the side plate 203 are bent perpendicularly. On the other side of the fixed plate 201, a bent plate 202 is bent perpendicularly. The side plate 203 and the bent plate 202 are perpendicularly connected and welded together, so that the connecting plate 2 ultimately forms a three-dimensional frame structure with high torsional stiffness. This structure can effectively resist the torque and off-center load that may be generated in various directions during the use of the pedal, prevent the connection parts from twisting or loosening, and provide an extremely stable mounting base for the hook 1. At the same time, welding the bent plate 202 to the side plate 203 not only further consolidates its structural integrity, but also optimizes the force transmission path: the load borne by the pedal can be transmitted more smoothly through the fixed plate 201 and the side plate 203 to the bent plate 202, and finally acted on the scaffold crossbar by the hook 1, ensuring efficient and direct load transmission and reducing potential structural fatigue points.

[0024] See Figure 1 , Figure 2 The bent plate 202 is welded and fixed to two sets of hooks 1. The hooks 1 have a "U" shape. Compared with J-shaped hooks or other forms, the "U"-shaped hooks have a larger contact area with the circular crossbar of the scaffold and a better fit. This surface contact method can significantly reduce the pressure at the contact point, reduce the wear on the coating of the crossbar, and provide more stable suspension support. It also reduces the risk of the pedal slipping laterally under the action of lateral force. At the same time, the setting of welding two sets of hooks 1 on the bent plate 202 constitutes a double hook suspension system, which realizes static determinate support and can effectively prevent the pedal from rotating around the vertical axis, ensuring the directional stability of the pedal after placement. The two hooks share the load and provide redundant safety backup.

[0025] See Figure 1 , Figure 2 , Figure 3 , Figure 4 Both the connecting plate 2 and the hook 1 are made of Q235B carbon structural steel. Q235B steel is a widely used material in the construction industry. Its yield strength is 235MPa, which has a good combination of strength, plasticity and toughness. It can meet the mechanical performance requirements of scaffolding boards under construction live loads and dynamic loads, ensuring that the components will not yield or brittle fracture under normal use. At the same time, Q235B steel also has good weldability and processability, and its cost is relatively low, making it very suitable for large-scale production. This material indicates that the product can undergo surface treatments such as hot-dip galvanizing before leaving the factory, thus possessing excellent corrosion resistance and being able to withstand harsh environments such as sun and rain on the construction site, significantly extending the service life of the product, reducing maintenance needs, and balancing durability and economy.

[0026] See Figure 1 The surface of the main body 4 of the tread plate has several through holes. When workers are working in wet and slippery weather, water or mud on the soles of their shoes can easily cause them to slip on the tread plate. These through holes can drain liquids and debris in time, increasing the actual contact area and friction between the soles of their shoes and the tread plate. Like countless tiny drainage channels and anti-slip teeth, these through holes greatly reduce the risk of workers slipping and falling, fundamentally improving the safety of working at heights. At the same time, the presence of these through holes can also effectively reduce the weight of the tread plate itself, making it easier to carry and install individual tread plates, and improving the efficiency of erection and dismantling. They also reduce the windward area of ​​the tread plate, reducing the wind load on the scaffolding system in windy weather and enhancing the overall stability.

[0027] The implementation principle of this embodiment is as follows: First, the hook 1 of the "U" structure is welded to the bent plate 202 of the connecting plate 2 to form an independent hanging unit. Second, the connecting plate 2 itself is composed of a fixed plate 201, a vertically bent side plate 203 and a bent plate 202. The fixed plate 201 and the side plate 203 are respectively provided with a first through hole 204 and a second through hole 205. Finally, during installation, the bolts 3 are passed through the first through hole 204 and the second through hole 205 on the connecting plate 2 and the corresponding holes on the pedal body 4 and tightened, so that the connecting plate 2 with the hook 1 is firmly assembled on both sides of the pedal body 4. This design makes the hook 1 and the pedal body 4 two separable parts, which improves the convenience of transportation and storage, and can be adapted to various scaffold crossbars by replacing the connecting plate 2 of different specifications, which enhances the versatility and maintenance convenience.
