The invention has the beneficial effects that:
1) The invention constructs the walking platform and the protection net matched with the walking platform into a modular structure, namely the walking platform and the protection net rack form an integral modular structure which can be arranged along the wall of a building or a structure in a sectional way and can be spliced together in pairs. When construction is needed, a constructor can make a plurality of scaffold modules according to the technical scheme of the invention, the length of each scaffold module can be set to be a fixed size, and of course, the scaffold modules can also be set to be a combination of different sizes, so that the scaffold can be suitable for construction of building walls with different lengths and building corners or corners. In addition, the scaffold module manufactured according to the integral modular structure can be repeatedly used in other building construction, so that the waste of materials and labor is greatly avoided.
2) The scaffold is manufactured according to an integral modular structure, namely, when the scaffold is assembled and installed, a walking platform and a protective net rack can be manufactured on a flat ground respectively and independently, and then the walking platform and the protective net rack are combined and fixed together in pairs. Therefore, the scaffold is convenient to produce and manufacture, high in construction efficiency and low in production cost, and meanwhile, the transportation and storage cost is greatly reduced.
3) The scaffold is manufactured in a split mode and integrally installed on the support frame, and is simple in structure, high in safety and convenient to lift. Certainly, the walking platform and the protective net frame can be made into a whole with the supporting frame, so that the integrity of the scaffold is further improved.
4) The bottom of the walking platform is provided with a sliding groove, and due to the existence of the sliding groove, the position of the walking platform can slide relative to the support frame, so that when the walking platform needs to be adjusted due to combination splicing during installation, or the position of a fastening bolt needs to be adjusted due to changes of the vertical surfaces of the upper floor and the lower floor of a building, the nut in the first connecting device can be loosened, and then the walking platform can be slid. Therefore, the scaffold is convenient to install, the moving position of the scaffold is easy to adjust, and the mechanical strength of the support frame is not affected, so that the convenience of scaffold installation and construction is greatly improved.
5) The problem that the nuts in the scaffold fall and are lost is a common problem, the falling nuts not only influence the personal safety of constructors, but also bring great troubles to the installation of the scaffold. In the prior art, a steel wire rope and other connecting parts are welded on a support frame, and then the steel wire rope and a nut are welded together to prevent the nut from falling and losing. However, the welding point between the steel wire rope and the nut is easily corroded to cause the separation of the steel wire rope and the nut, and the welding point between the steel wire rope and the support frame is also easily corroded to cause the steel wire rope to easily fall off, so that the operation mode has the problem of low safety.
The anti-lost enclosure structure is creatively used, namely the anti-lost enclosure structure is fixedly arranged on the support frame in a welding or other mode, the nut welded with the anti-rotation part is placed in the anti-lost enclosure structure, the anti-rotation part cannot be separated from an area surrounded by the anti-lost enclosure structure due to the size of the anti-lost enclosure structure, and the anti-rotation part cannot rotate in the anti-lost enclosure structure due to the matching of the shape of the anti-lost enclosure structure and the shape of the anti-rotation part, so that the structure not only effectively avoids the falling and the loss of the nut, but also is very convenient for the connection and the fixation of the bolt and the nut.
6) Compared with the traditional externally-hung scaffold structure, the modularized externally-hung scaffold has the advantages of simple structure, convenience in construction, good safety, lower installation and construction cost, convenience in lifting, repeated use and suitability for wall facades of various buildings.
