Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a disc-lock scaffold. Background Technology

[0002] Scaffolding is a commonly used construction tool, a working platform erected to ensure the smooth progress of various construction processes. It can be categorized by location (external scaffolding, internal scaffolding); by material (wooden scaffolding, bamboo scaffolding, steel pipe scaffolding, etc.); and by structural form (pole-type scaffolding, bridge-type scaffolding, frame-type scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, climbing scaffolding, disc-lock scaffolding, etc.).

[0003] The connection technology of disc-lock scaffolding originated in Germany and is the mainstream product in Europe and America. Currently, the horizontal and diagonal braces of disc-lock scaffolding on the market are fixed to the connecting flanges using pins. However, common pins are usually made of metal rods that are larger at one end and smaller at the other. Because disc-lock scaffolding will sway during use, the pins may move upwards, which could cause them to fall off. This compromises the stability of the fixation and reduces safety. Summary of the Invention

[0004] The present invention aims to provide a disc-lock scaffolding to solve the problem that existing pins may move upward and fall during use, thus compromising safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a disc-lock scaffold, comprising uprights, horizontal bars, diagonal bars, and pins. The uprights are provided with several connecting discs, each with several mounting holes. Both ends of the horizontal bars are fixedly connected to horizontal bar connectors, and both ends of the diagonal bars are fixedly connected to diagonal bar connectors. The front ends of the horizontal bar connectors and diagonal bar connectors have mounting grooves that mate with the connecting discs. The top ends of the horizontal bar connectors and diagonal bar connectors have through-holes that mate with the mounting holes. The pins pass through the fixing holes and the mounting holes. The bottom end of the pin's sidewall has a fan-shaped movable groove. A stop block is provided within the movable groove, rotatably connected to the center of the fan-shaped movable groove. Fixing blocks are provided on both sides of the stop block. Moving grooves that mate with the fixing blocks are provided on both sides of the movable groove. A return spring is provided between the moving groove wall and the fixing block.

[0006] Preferably, a number of horizontal bars and diagonal bars can be installed on one of the connecting plates.

[0007] Preferably, the front end of the mounting groove has a chamfer.

[0008] The principle and beneficial effects of this technical solution:

[0009] Disc-lock scaffolding uses connecting discs on uprights with mounting holes. Both ends of horizontal and diagonal members are fixedly connected to disc connectors. The front end of each disc connector has a mounting groove that mates with the connecting disc, allowing for quick connection between the horizontal and diagonal members and the connecting disc on the upright, ensuring fast construction. The top of the disc connector has a through-hole that mates with the mounting hole on the connecting disc. A pin passes through both the through-hole and the mounting hole to secure the structure. The bottom of the pin's side wall has a fan-shaped movable groove with a stop block inside. The stop block rotatably connects to the center of the movable groove. Fixed blocks are located on both side walls, and movable grooves on both side walls mate with the fixed blocks. A return spring is located between the movable groove wall and the fixed block. This design effectively prevents the pin from moving upwards and falling off during use, improving safety. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0016] like Figure 1The illustrated disc-lock scaffold includes uprights 7, horizontal bars 4, diagonal bars 5, and pins 2. The uprights 7 are provided with several connecting discs 1, each with several mounting holes 9. Both ends of the horizontal bars 4 are fixedly connected to horizontal bar connectors 3, and both ends of the diagonal bars 5 are fixedly connected to diagonal bar connectors 6. The front ends of the horizontal bar connectors 3 and diagonal bar connectors 6 have mounting grooves 8 that mate with the connecting discs 1. The top ends of the horizontal bar connectors 3 and diagonal bar connectors 6 have through-holes 10 that mate with the mounting holes 9. The pins 2 pass through the 10 and 9. The bottom of the side wall of the pins 2 has a fan-shaped movable groove 11. A stop block 12 is provided within the movable groove and is rotatably connected to the center of the fan-shaped movable groove 11. Fixing blocks 13 are provided on both sides of the stop block 12. Moving grooves 14 that mate with the fixing blocks 13 are provided on both sides of the movable groove. A return spring is provided between the groove wall of the moving groove 14 and the fixing blocks 13.

[0017] Several horizontal bars 4 and diagonal bars 5 can be installed on a connecting plate 1.

[0018] The front end of mounting slot 8 has a chamfer.

[0019] The specific implementation process is as follows:

[0020] During use, install the required horizontal bar 4 and diagonal bar 5 on the connecting plate 1 according to the design. During installation, align the mounting hole 9 and fixing hole 10. After confirming the correct position, use a hammer to push the pin 2 through the two holes to complete the installation. During installation, the stop block 12 will retract into the fan-shaped movable groove 11 under the action of the hole walls of the mounting hole 9 and fixing hole 10. After passing through the two holes completely, it will extend under the action of the return spring to prevent the pin 2 from moving upward. When removing, hold the stop block 12 with your hand or clamps and let it enter the fan-shaped movable groove 11. Hammer the bottom of the pin 2 or pull the pin 2 upward directly to make the corresponding part of the fan-shaped movable groove 11 enter the area of ​​the two holes. Release your hand or clamps and continue to hammer the pin 2 or pull it upward to remove the pin 2.
