Description

A construction scaffolding that is easy to assemble and disassemble

technical field

The utility model relates to the technical field of construction, in particular to a construction scaffold used on a construction site.

Background technique

During the construction process, in order to ensure the safe construction environment of the operators, construction scaffolding is usually erected. According to the requirements of the construction code, set up a connecting wall piece every two steps and three spans or two steps and two spans to achieve overall stability. Pre-embedded steel pipes in concrete are often used as connecting wall parts to connect the scaffolding frame with the main body of the building. After the completion of construction, such wall-connecting parts need to be cut off of the embedded steel pipes, which will cause waste of materials. In addition, due to the untimely removal, large scaffolding holes will be left during the secondary structure wall masonry in the later stage. Repairs, plastering and external wall insulation can only be carried out after the scaffolding is completely removed, which will bring large repairs. Work volume. Therefore, the industry is in urgent need of a construction scaffold that can avoid material waste and bring convenience to later construction.

Utility model content

The utility model is used to solve the defects of the prior art, and provides a construction scaffold which is convenient for assembly and disassembly. The design scheme can not only save cost, but also provide convenience for later construction.

The technical solution adopted to solve the above problems is as follows:

A construction scaffold that is easy to assemble and disassemble includes a scaffold body and a wall connecting piece connected with the main structure of a building. The scaffold frame body is composed of fasteners and steel pipes, etc.; the wall connecting parts include baffles, screws, nuts and cross bars. One end of the cross bar is welded with a nut corresponding to the diameter of the screw, the cross bar is connected with the screw through the nut, and the screw is welded at the center of the baffle. The casing of the corresponding wall thickness of the screw jacket is pre-embedded into the main body of the building before concrete pouring. Setting the casing can be convenient for assembly and disassembly, and it can be used repeatedly in turnover.

The utility model designs a construction scaffold which is easy to assemble and disassemble aiming at solving the defects of the prior art. The scaffold body is reliably connected to the main structure of the building through the wall connecting piece. The screw rod in the wall-connecting structure is provided with a sleeve. After the construction is completed, the screw rod is disassembled from the main body of the building and can be used repeatedly, avoiding the waste of materials caused by cutting off the embedded steel pipe. The threaded connection between the screw rod and the cross bar is convenient for assembly and disassembly, which brings convenience to the later construction and avoids the pre-embedded steel pipes hindering the masonry during the construction of the secondary structure masonry. The diameter of the screw is ￠20, and the inner diameter of the casing is ￠25. After the construction is completed, the casing is buried in the main body of the building. Compared with ordinary scaffolding, the building entity has smaller scaffolding eyes, and the amount of secondary maintenance work is greatly reduced. Materials are saved, the amount of work is reduced, and the cost of a single project can save more than 10,000 to 20,000 yuan. The utility model has the advantages of simple structure, low cost and easy realization, and is suitable for popularization and use in building construction sites.

detailed description

Referring to Fig. 1, the utility model provides a construction scaffold that is easy to assemble and disassemble, including a scaffold body and a wall connecting piece connected with the main structure of the building. The scaffold frame body is composed of fasteners and steel pipes, etc.; the wall connecting parts include baffles, screws, nuts and cross bars. The baffle is a square iron plate with a side length of 8cm-10cm, preferably an iron plate of 10cm*10cm*0.5cm; the screw and the baffle are welded together, and the length of the screw depends on the thickness of the wall, 20cm-40cm Among them, the first-class steel with a diameter of ￠20 and a length of 25cm is preferred, and the thread length is 5cm-10cm; the crossbar is a steel pipe with an outer diameter of 48mm and a wall thickness of 3.5mm, and the length depends on the distance between the scaffold and the main structure of the building and the inner and outer poles. Depending on the distance, the preferred size is 1.5m; one end of the crossbar is welded with a nut of the corresponding diameter to the screw. The inner diameter of the casing is ￠25, the screw is covered with the casing, and the thread of 5cm is exposed, and the casing is pre-buried in the main body of the building. The cross bar is connected with the screw rod through the nut, and the cross bar is connected with the inner and outer poles of the scaffold with fasteners.
