Description

Technical Field

[0001] This utility model relates to a construction scaffold that can be fitted with protective netting, and belongs to the field of [specific field]. Background Technology

[0002] Construction scaffolding equipped with safety netting is an indispensable safety facility in modern construction projects. It primarily provides a safe and stable working platform for construction workers and prevents injuries from falling tools and materials. A construction platform with a ladder is a type of scaffolding. On the side of the platform facing away from the wall, a diagonal tube is installed via couplers. The lower end of the diagonal tube connects to the ladder, forming a triangular structure. When there are many items on the platform, the couplers connecting the diagonal tube and the platform, as well as the connection points between the diagonal tube and the platform, are subjected to significant forces, leading to relative slippage and decreased structural stability and safety. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a construction scaffold that can be equipped with a protective net to solve the problems mentioned in the background technology. This utility model prevents relative slippage of the fasteners between the inclined pipe and the construction platform and the connection parts of the inclined pipe under stress, thereby improving safety.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a construction scaffold capable of being fitted with protective netting, comprising two parallel horizontal tubes, with multiple footboards overlapping between the two horizontal tubes. A first vertical tube and a second vertical tube are respectively installed at both ends of the horizontal tubes via cross-shaped fasteners. An inclined ladder is installed at the end of the horizontal tube closest to the first vertical tube, and an arc-shaped overlap is installed at the end of the ladder closest to the horizontal tube. A reinforcing tube is provided directly above each of the two horizontal tubes, and both ends of the reinforcing tube are connected to the first vertical tube and the second vertical tube respectively via cross-shaped fasteners. Connecting tubes are installed at the upper ends of the two second vertical tubes via cross-shaped fasteners. Aluminum profile guide rails are installed on each of the two second vertical tubes, and a wire mesh is inserted between the two aluminum profile guide rails. An inclined tube is connected to the end of the horizontal tube furthest from the first vertical tube via a structure formed by a support lug and fasteners. The lower end of the inclined tube is connected to the ladder, and a positioning element for limiting the position of the wire mesh is installed between the inclined tube and the wire mesh.

[0005] Furthermore, the positioning component includes a rectangular tube, two rectangular tubes are installed on one side of the iron mesh, a rectangular rod is inserted inside the rectangular tube, a positioning screw is threaded to the side of the upper surface of the rectangular tube away from the iron mesh, a connecting plate is installed at the end of the rectangular rod outside the rectangular tube through an adjusting component, an L-shaped plate is rotatably connected to the lower end of the connecting plate, a ring is installed at the end of the L-shaped plate away from the connecting plate, the ring is sleeved on the inclined tube and the inclined tube is located below the fastener on the inclined tube.

[0006] Furthermore, the adjusting component includes a U-shaped plate, with the U-shaped plate installed at one end of the rectangular rod outside the rectangular tube, a screw installed inside the U-shaped plate, a through hole at the upper end of the connecting plate, the screw passing through the through hole, and a first nut provided on both sides of the through hole along the length of the screw.

[0007] Furthermore, small holes are provided on both parallel sides of the U-shaped plate, and the two ends of the screw pass through the two small holes respectively. A second nut is threaded to both ends of the screw, and the U-shaped plate is disposed between the two second nuts.

[0008] Furthermore, an end plate is installed at one end of the rectangular tube near the iron mesh, and the end plate is fixedly connected to the iron mesh.

[0009] Furthermore, a semi-circular groove is machined on one side of the aluminum profile guide rail, the second vertical tube is inserted into the semi-circular groove, and a slot is machined on the side of the aluminum profile guide rail away from the semi-circular groove, with one end of the iron mesh inserted into the slot.

[0010] Furthermore, a support lug is installed on the upper part of the arc-shaped section surface of the overlapping part, and a support wheel is rotatably mounted on the support lug via a rotating shaft.

[0011] The beneficial effects of this utility model are:

[0012] 1. Adjust the length of the rectangular rod inside the rectangular tube according to the inclination angle of the inclined tube. Then, use the positioning screws to limit the relative position of the rectangular rod and the rectangular tube. Adjust the relative position of the connecting plate and the L-shaped plate so that the ring contacts the lower surface of the fastener connecting the horizontal and inclined tubes. At this time, the force acting on the fastener connecting the horizontal and inclined tubes will be applied to the wire mesh through the ring, connecting plate, rectangular rod, and rectangular tube. The wire mesh will then apply the force to the horizontal tube, preventing the fastener connecting the horizontal and inclined tubes from sliding downwards. This prevents relative sliding of the fastener and the connection between the inclined tube and the construction platform due to force, thus improving safety.

[0013] 2. After installing a structure consisting of rings, L-shaped plates, connecting plates, rectangular rods, and rectangular tubes between the wire mesh and the fasteners connecting the horizontal and inclined tubes, multi-point support for the wire mesh is achieved, improving the stability of the wire mesh installation.

[0014] 3. Adjust the position of the connecting plate along the screw according to the distance between the two inclined tubes. At this time, the distance between the two rings will change. When the distance between the two rings meets the distance requirement of the two inclined tubes, the relative position of the screw and the U-shaped plate can be restricted by the two first nuts. This method is suitable for different distances between the two inclined tubes. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1 and Figure 3 This utility model provides a technical solution: a construction scaffold that can be fitted with protective netting, comprising two parallel horizontal pipes 1, with multiple footboards 7 overlapping between the two horizontal pipes 1, and vertically arranged first vertical pipes 5 and second vertical pipes 11 respectively installed at both ends of the horizontal pipes 1 by cross couplers, and reinforcing pipes 6 provided directly above the two horizontal pipes 1, with both ends of the reinforcing pipes 6 connected to the first vertical pipe 5 and the second vertical pipe 11 respectively by cross couplers, and connecting pipes 8 installed at the upper ends of the two second vertical pipes 11 by cross couplers, the connecting pipes 8, reinforcing pipes 6, first vertical pipes 5, second vertical pipes 11, footboards 7 and horizontal pipes 1 together forming a construction platform.

[0024] See Figure 1A ladder 2 is installed at an angled position on one end of the horizontal pipe 1 near the first vertical pipe 5. An arc-shaped overlapping part 3 is installed on the other end of the ladder 2 near the horizontal pipe 1. A support lug is installed on the upper part of the arc-shaped surface of the overlapping part 3. A support wheel 4 is installed on the support lug by rotating through a pivot. After the ladder 2 is separated from the horizontal pipe 1, the support wheel 4 contacts the ground, making it easy to move the position of the ladder 2 by pulling. This allows one person to move the position of the ladder 2.

[0025] See Figures 1-4 Aluminum profile guide rails 20 are installed on both second vertical pipes 11. A wire mesh 9 is inserted between the two aluminum profile guide rails 20. That is, a semi-circular groove is machined on one side of the aluminum profile guide rail 20, and the second vertical pipe 11 is inserted into the semi-circular groove. A slot is machined on the side of the aluminum profile guide rail 20 away from the semi-circular groove, and one end of the wire mesh 9 is inserted into the slot. The end of the horizontal pipe 1 away from the first vertical pipe 5 is connected to the inclined pipe 10 through the structure formed by the support lug and the fastener. The lower end of the inclined pipe 10 is connected to the ladder 2. The inclined pipe 10, the horizontal pipe 1 and the ladder 2 form a triangular structure to improve the stability of the structure.

[0026] See Figure 1 , Figure 2 and Figure 5 Two rectangular tubes 19 are installed on one side of the wire mesh 9. An end plate 21 is installed at the end of each rectangular tube 19 closest to the wire mesh 9, connecting and fixing the end plate 21 to the wire mesh 9, thus increasing the connection range between the rectangular tube 19 and the wire mesh 9. A rectangular rod 17 is inserted inside the rectangular tube 19. A positioning screw 18 is threaded onto the upper surface of the rectangular tube 19 away from the wire mesh 9. A U-shaped plate 16 is installed at the outer end of the rectangular rod 17 outside the rectangular tube 19. A screw 15 is installed inside the U-shaped plate 16. A through hole is opened at the upper end of the connecting plate 14, through which the screw 15 passes. First nuts 22 are provided on both sides of the through hole along the length of the screw 15. The screw 15 is positioned according to the distance between the two inclined tubes 10. The rod 15 adjusts the position of the connecting plate 14, at which point the distance between the two rings 12 changes. When the distance between the two rings 12 meets the distance requirement of the two inclined tubes 10, the relative position of the screw 15 and the U-shaped plate 16 can be restricted by the two first nuts 22. This is suitable for the different distances of the two inclined tubes 10. Small holes are opened on the two parallel sides of the U-shaped plate 16. The two ends of the screw 15 pass through the two small holes respectively. The two ends of the screw 15 are threaded with second nuts 23. The U-shaped plate 16 is placed between the two second nuts 23. The two second nuts 23 cooperate with the screw 15 to realize the assembly of the screw 15 and the U-shaped plate 16.

[0027] See Figures 1-5An L-shaped plate 13 is rotatably connected to the lower end of the connecting plate 14. A ring 12 is installed at the end of the L-shaped plate 13 away from the connecting plate 14. The ring 12 is sleeved on the inclined tube 10, and the inclined tube 10 is located below the fastener on the inclined tube 10. According to the inclination angle of the inclined tube 10, the length of the rectangular rod 17 inside the rectangular tube 19 is adjusted. Then, the relative position of the rectangular rod 17 and the rectangular tube 19 is limited by the positioning screw 18. The relative position of the connecting plate 14 and the L-shaped plate 13 is adjusted so that the ring 12 contacts the lower surface of the fastener connecting the horizontal tube 1 and the inclined tube 10. At this time, the force acting on the fastener connecting the horizontal tube 1 and the inclined tube 10 will... The components such as the circular ring 12, connecting plate 14, rectangular rod 17, and rectangular tube 19 act on the iron mesh 9, and the iron mesh 9 applies the force to the horizontal tube 1, so that the fasteners connecting the horizontal tube 1 and the inclined tube 10 will not slide downwards. This prevents relative sliding of the fasteners between the inclined tube 10 and the construction platform and the connection parts of the inclined tube 10 under stress, thus improving safety. After installing the structure formed by the circular ring 12, L-shaped plate 13, connecting plate 14, rectangular rod 17, and rectangular tube 19 between the iron mesh 9 and the fasteners connecting the horizontal tube 1 and the inclined tube 10, multi-point support is achieved for the iron mesh 9, improving the stability of the iron mesh 9 installation.
