Description

Technical Field

[0001] This utility model relates to the field of building construction equipment, and in particular to a scaffolding external steel wire rope inclined tension assembly device. Background Technology

[0002] External scaffolding, an indispensable part of construction, is installed on the exterior of buildings and serves as a temporary structural frame for material handling, stacking, and construction operations, facilitating construction. It also ensures the safety of construction workers operating at heights, providing necessary footholds and external protective support. Furthermore, it offers advantages such as easy assembly and disassembly, flexible erection, simple fabrication, and relatively low initial investment costs.

[0003] When constructing external scaffolding, it is usually necessary to install diagonal guy lines to provide tension. Combined with the supporting columns of the scaffolding, this can improve the overall stability and safety of the scaffolding. After the diagonal guy lines are connected, it is necessary to ensure that they have sufficient tension to guarantee sufficient pulling force.

[0004] Currently, tensioning is mainly carried out in pairs. During the operation, one person manually pulls the end of the guy line to tighten it, and after tightening, the other person locks the end of the rope with a lock to lock the tension. This method provides limited tension to the guy line, and it is easy to loosen after workers step on it during construction. Utility Model Content

Detailed Implementation

[0022] Example 1, see appendix to the instruction manual. Figure 1 , 5 -6. A scaffolding external steel wire rope inclined tensioning assembly device includes an external scaffolding plate 12 installed on the outside of a building 15 via a column system 11. The column system supports the external scaffolding plate from below, keeping it horizontal. The device also includes several tension ropes 13 inclinedly connected between the building 15 and the outside of the external scaffolding plate 12. These tension ropes are spaced at the same interval to provide uniform tension to the external scaffolding plate 12. The outer edge of the external scaffolding plate is provided with a hook, and the outer ends of the tension ropes 13 are wrapped around the hook. The structure forms a double rope head 131, with at least two U-shaped clips 14 connected between the double rope heads. The U-shaped clips lock the connection between the pull rope 13 and the hook. The building body 15 is provided with a fixing hook 151, on which a puller is attached. The lower end of the puller is connected to the free end of the rope head 131 of the pull rope 13. The puller provides tension to the rope head 1 of the pull rope, wrapping and tightening the lower end of the pull rope 13 onto the hook, and then locking it in place with the U-shaped clips 14.

[0023] The building body 15 is provided with several hanging ear loops 152. The upper end of the pull rope 13 is wrapped around the hanging ear loop 152 and locked by the rope buckles 17 arranged side by side. The two hanging rings provide a hanging point for the pull rope 13 on the upper part of the building body 15.

[0024] Example 2, see appendix Figure 3-4 This embodiment is basically the same as Embodiment 1, except that: the hanging component is set as a square hanging frame 18, which is welded and fixed to the outer frame plate 12 as a whole. Several reinforcing vertical bars 182 are evenly arranged between the horizontal bars 181 of the square hanging frame 18. The tensile strength of the square hanging frame is improved by the reinforcing vertical bars. The pull rope 13 is connected to the horizontal bar 181 at the top of the square hanging frame 18. The reinforcing vertical bars 182 play the role of limiting and blocking the pull rope 13, avoiding the problem of serious positional deviation caused by large lateral movement of the lower end of the pull rope 13. The length of the square hanging frame 18 is set to be the same as the length of the outer frame plate 12. The square hanging frame extends upward to the upper surface of the outer frame plate. The extended part of the square hanging frame 18 can form a guardrail structure, and the building materials and building tools placed on the square hanging frame are not likely to fall off.

[0025] Example 3, see appendix Figure 1-3 This embodiment is basically the same as Embodiment 1, except that the puller is a manual hoist 16. A hook 161 is located in the middle of the upper part of the manual hoist. The hook is connected to the manual hoist 16 by a rotating connection. The hook 161 is attached to a fixed hook 151 or to a hanging loop 152. A clamp 163 is located at the lower end of the chain 162 of the manual hoist 16. The clamp is fastened to the rope end 131 at the lower end of the pull rope 13. The clamp 163 allows for convenient and quick... The connection between the chain 162 and the rope head 131 can be established, or the two can be connected by binding, as long as the connection is stable; the U-shaped clamp 14 includes a U-shaped bolt 141 and a clamping plate 142. The clamping plate has two through holes arranged side by side on its surface. The two through holes are matched and fitted onto the U-shaped bolt. The clamping plate 142 can slide along the U-shaped bolt 141. A nut 143 is installed on the part of the U-shaped bolt 141 that extends out of the clamping plate 142. Rotating the nut can push the clamping plate 142 inward.

[0026] The process of using this device for inclined construction is as follows: Connect the upper end of the pull rope 13 with the ear loop 152, and after the lower end of the pull rope passes around the hanger, it forms an overlap. Put the U-bolt 141 on the overlap, put the clamping plate 142 on the U-bolt 141, and screw the nut 143 on the end of the U-bolt. Keep the nut 143 connected, but do not press the clamping plate 142 tightly. Then pull out the chain 162 of the manual hoist 16 and clamp the lower end of the chain 163 onto the rope end 131 of the pull rope 13. Drive the manual hoist 16 to pull the chain 162. The chain gradually tightens the rope end 131 of the pull rope 13. The strong pulling force of the manual hoist 16 keeps the pull rope 13 taut. Then screw the nut 143 to lock the clamping plate 142 onto the pull rope 13. The connection of the pull rope is locked in the taut state, and it is not easy for loosening to occur in the later construction.
