Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction equipment, in particular to a rotatable tensioning screw wall connecting device. Background Art
[0002] Steel pipe scaffolding is a temporary structure widely used in construction. It is used to provide a working platform for construction workers, material stacking and transportation channels. It is usually composed of steel pipes, fasteners, bases, adjustable supports and other components. It has the characteristics of large load-bearing capacity, flexible erection and easy use.
[0003] The scaffolding wall tie system is a crucial component for ensuring its overall stability. It effectively reduces the slenderness ratio of the scaffolding's load-bearing members and promptly transfers the horizontal wind loads acting on the scaffolding to the building structure. Currently, most scaffolding wall ties are constructed using methods such as embedded steel pipes, a combination of bracing and tensioning, post-anchoring, hoop columns, and embedded iron plates. External beams are typically supported by exterior walls, bay windows, and railings. Installing these wall ties significantly impacts secondary structure construction and railing installation. Later in the construction and plastering process, the wall ties must be removed and holes repaired, incurring additional costs and potentially introducing potential leakage risks from the exterior wall repair holes.
[0004] Therefore, those skilled in the art are committed to developing a revolving tensioning screw wall connection device, which is beneficial to the firm connection between the steel pipe scaffolding and the wall, and improves the bearing capacity and anti-collapse ability of the steel pipe scaffolding.

[0041] like Figure 1 、 Figure 2 and Figure 3 As shown, a revolvable tensioning screw wall connection device includes a connecting screw 1, which passes through a wall 2 and extends out of both ends of the wall 2;
[0042] A first locking assembly 3, which is connected to one end of the connecting screw 1 and abuts against the wall 2;
[0043] Connecting fastener 4, connecting fastener 4 is connected with connecting screw 1 and steel pipe scaffold 5;
[0044] The second locking assembly 6 is connected to the connecting screw 1 and abuts against the connecting fastener 4.
[0045] In the utility model, one end of the connecting screw 1 is connected to the wall 2 through the first locking assembly 3, and the other end is connected to the steel pipe scaffolding 5 through the connecting fastener 4, and then further connected and fixed through the second locking assembly 6, so that the steel pipe scaffolding 5 is firmly connected to the wall 2, thereby improving the bearing capacity and anti-collapse ability of the steel pipe scaffolding 5.
[0046] like Figure 1 、 Figure 2 As shown, in some embodiments, the first locking assembly 3 includes at least one first locking bolt 7. In this embodiment, two first locking bolts 7 are provided. The first locking bolts 7 are sleeved on the connecting screw 1. A first gasket 8 is provided between the first locking bolt 7 and the wall 2. The first gasket 8 can be a steel gasket.
[0047] In another embodiment, an intermediate sleeve 9 is provided between the connecting fastener 4 and the wall 2, and the connecting screw 1 is passed through the intermediate sleeve 9. A second gasket 10 is also installed at the end of the intermediate sleeve 9 and on the side abutting against the wall 2. The second gasket 10 can also be a steel gasket.
[0048] In the embodiment, the second locking assembly 6 includes at least one second locking bolt 11, two of which are provided in this embodiment. A clamping member 12 is further provided between the second locking bolt 11 and the intermediate sleeve 9. Specifically, the clamping member 12 is generally mountain-shaped and includes a clamping block 13. The clamping block 13 is provided with a through hole for the connecting screw 1 to pass through. Support fins 14 are further connected to both ends of the clamping block 13. During use, the clamping block 13 is engaged within the intermediate sleeve 9, and the two support fins 14 abut against the wall of the intermediate sleeve 9.
[0049] like Figure 1 、 Figure 2 and Figure 3 As shown, in one embodiment, the connecting fastener 4 is further mounted with a snap-fit assembly for engaging the intermediate sleeve 9. Specifically, the snap-fit assembly includes a connecting block 15 fixedly connected to the connecting fastener 4. The connecting block 15 is disposed opposite the intermediate sleeve 9. The connecting block 15 is provided with a dovetail groove 16. The dovetail groove 16 contains a first snap-fit member 17 and a second snap-fit member 18. The first snap-fit member 17 and the second snap-fit member 18 are both provided with snap-fit cavities for engaging the intermediate sleeve 9 at opposing positions.
