Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a reverse pulling device for installing and fixing a climbing frame. Background Art

[0002] With the continuous emergence of high-rise and super-high-rise buildings, the increase in height means higher construction technology requirements. The construction enclosure scheme of high-rise and super-high-rise buildings is often regarded as a technical difficulty in the construction projects. However, the owners' requirements for construction schedules are becoming more and more stringent. During the construction period, the form of external enclosure is comprehensively considered in terms of safety, construction schedule, cost and other factors. Most projects often choose attached climbing scaffolding as the best high-rise enclosure scheme.

[0003] However, since the wall-mounted supports of the attached climbing scaffolding are located on the cantilever, the bearing capacity of the main structure at the supports is insufficient, and the connections may bend and loosen due to excessive load, which poses a greater safety risk and shortens the service life of the scaffolding. Utility Model Content

[0004] The purpose of the utility model is to provide a back-pull device for installing and fixing a climbing frame. By arranging a back-pull sleeve, a nut, a positive thread screw, a reverse thread screw and a triangular iron piece, the utility model solves the problem that the attached climbing scaffolding has insufficient bearing capacity of the main structure at the support due to the wall support being arranged on the cantilever plate, and the connection is prone to bending and loosening due to excessive load, which poses a greater safety risk and leads to a shorter service life of the scaffolding.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a reverse pulling device for installing and fixing a climbing frame, comprising a reverse pulling sleeve, nuts are welded at both ends of the reverse pulling sleeve, the bottom end of the reverse pulling sleeve is threadedly connected to a positive threaded screw rod through a nut, and the top end of the reverse pulling sleeve is threadedly connected to a negative threaded screw rod through a nut, and one end of the positive threaded screw rod and the negative threaded screw rod are both welded with a perforated steel plate.

[0006] Preferably, an A pin is inserted into the interior of the perforated steel plate at the bottom, and the perforated steel plate at the bottom is rotatably connected to an A rotating seat through the A pin.

[0007] Preferably, a triangular iron piece is welded to the bottom of the A rotating seat, and a climbing frame support is fixedly installed on one side of the triangular iron piece by a tension screw.

[0008] Preferably, a socket is provided on the upper surface of the triangular iron piece, and a through-wall screw A for fixing the cantilever beam A is inserted into the socket.

[0009] Preferably, a B pin is inserted into the interior of the perforated steel plate at the top, and the perforated steel plate at the top is rotatably connected to a B rotating seat through the B pin.

[0010] Preferably, a hole is provided on one side of the B rotating seat, and a B through-wall screw for fixing the B cantilever beam is inserted into the hole.

[0011] Preferably, both ends of the tension screw, the A through-wall screw and the B through-wall screw are threadedly connected with hexagonal nuts, and a gasket is provided on one side of the hexagonal nut.

[0012] The utility model provides a reverse pulling device for installing and fixing a climbing frame, which has the following beneficial effects:

[0013] This patented technology is applicable to the structures in which the attached climbing scaffolding is used as the facade protection during the construction of high-rise and super high-rise buildings and the cantilever plates are designed around the main structure. By adopting the anti-pull device to transfer the load of the climbing frame to the constructed main structure, it can not only ensure the overall rigidity and stability of the climbing frame, but also avoid the quality problem of the conventional construction method of tying the climbing frame to the cantilever structure, which may cause the cantilever structure to be overloaded and the safety risk of instability of the climbing frame. It reduces the load of the climbing frame wall support on the structural cantilever plate to ensure the safety of the main structure and the installation and use of the climbing frame. The actual verification shows that the device has obvious effect, is easy to operate, can be recycled, and is green and environmentally friendly. Practice has proved that it has strong promotion and application value. BRIEF DESCRIPTION OF THE DRAWINGS
