Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a wall-attached support node structure of an attached lifting scaffold. Background Art

[0002] During construction, it is necessary to set up an automatically elevating work platform outside a building to facilitate pouring and finishing work. In the prior art, to facilitate the installation of an automatically elevating work platform, multiple wall-mounted supports are generally installed on the building's exterior from top to bottom to support the work platform, and the wall-mounted supports are used to perform the up and down operations.

[0003] The wall-mounted support primarily serves to guide, temporarily support, and prevent the lifting scaffold from falling. For example, the utility model patent CN216690301U includes a wall-mounted back plate, supporting side plates, a fixed panel, a load-reducing top brace, an internal mounting base, a guide plate, front and rear guide wheels, a fall prevention block, and a fall prevention block. The guide rails of the lifting scaffold are positioned between the front and rear guide wheels. As the lifting scaffold ascends, the guide wheels provide rolling contact and guidance for the lowering scaffold.

[0004] When climbing stops, the unloading brace is rotated to abut against the lifting scaffolding, thereby providing temporary support. However, in actual use, because the unloading brace is hinged to the wall-mounted support, the lifting scaffolding will move outward away from the wall-mounted support and cannot provide support on its own. Either a locking member such as a pin is used to limit the rotation of the unloading brace, or a guide wheel is used to limit the horizontal movement of the lifting scaffolding. However, both the locking member and the guide wheel need to bear a large load and are easily damaged and fail, posing a significant safety hazard.

[0005] Based on this, it is necessary to study a wall-attached support node structure for an attached lifting scaffold. Utility Model Content

When the lifting guide rail is lifted, the guide wheel and the limiting claw jointly limit the lifting guide rail; the lower end of the unloading support is hinged on the support. When the lifting guide rail stops, the unloading support can be rotated so that its top abuts against the lifting guide rail to form a support, and combined with the function of limiting the outward movement of the lifting guide rail, it can form a temporary support effect on the lifting guide rail. The load of this temporary support effect is mainly concentrated on the unloading support and the limiting claw, and will not affect or damage the guide wheel. There is no need to use locking parts such as pins. It can effectively solve the problem that when the unloading support produces a support effect, the locking part or the guide wheel needs to bear a large load and is easily damaged and fails, optimizes the force condition, and improves the reliability of the wall-mounted support.

[0038] (2) The compression spring rod can automatically adjust the position of the guide wheel to compensate for the slight deviation caused by the manufacturing and installation errors of the lifting frame, ensuring that the guide wheel always maintains close contact with the guide rail and provides a stable guiding effect.
