Description

Technical Field

[0001] This utility model relates to the field of construction, and further to a splicing steel tie rod for a flower basket frame and an external wall scaffolding. Background Technology

[0002] In the construction industry, a basket frame refers to a cantilevered scaffolding support system, mainly used in the construction of the exterior walls of high-rise or super high-rise buildings to provide a support platform for the scaffolding.

[0003] Currently, the length of steel tie rods in existing cantilever scaffolding is usually fixed. However, different building structures have different requirements for the length of steel tie rods on the construction site. The existing fixed-length steel tie rods of cantilever scaffolding cannot meet the requirements and need to be processed on the construction site, which affects the construction efficiency and has a significant impact on the organization and arrangement of the construction site.

[0004] Longer steel tie rods occupy a large space on the construction site and are quite heavy, which will take up a lot of construction space, increase the difficulty of transportation, hinder on-site construction operations, and reduce the efficiency of construction operations.

The second fixed end 22 of the lower pull rod 20 has a locking protrusion 221 extending outward in a direction perpendicular to the axial direction of the lower pull rod 20. During the process of inserting the second fixed end 22 of the pull rod 20 into the mounting groove 121, the locking protrusion 221 is adapted to move within the insertion groove 122. When the second fixed end 22 is inserted into the preset position within the mounting groove 121, the first fixing hole 120 and the second fixing hole 220 are offset from each other. When the pull rod 10 and the pull rod 20 are rotated relative to each other, such that when the locking protrusion 221 moves from the insertion groove 122 into the locking groove 123, at least one of the first fixing holes 120 corresponds to at least one of the second fixing holes 220. In this modified embodiment, during assembly, the locking protrusion 221 of the pull rod 20 is first aligned with the insertion groove 122 of the pull rod 10. During the process of installing the second fixed end 22 into the mounting groove 121, the locking protrusion 221 moves within the insertion groove 122. After the second fixed end 22 is inserted into the mounting groove 121 at a preset depth, the pull rod 10 and the pull rod 20 are rotated relative to each other, so that the locking protrusion 221 moves into the locking groove 123. The engagement between the locking groove 123 and the locking protrusion 221 can limit the pull rod 10 and the pull rod 20 in the axial direction, facilitating the passage of the first fastener through the first fixing hole 120 and the second fixing hole 220.
