Briefly describe the safety rules for the erection and dismantling of scaffolding

First, for the use of scaffolding in construction, samples should be taken and sent to relevant units to undergo a series of relevant inspections before use. Construction can be started, but if any of the items are unqualified, construction cannot be carried out, and construction can be started only after returning to the construction unit for revision and approval. The second point is that the supervisors and management personnel should conduct safety inspections on the scaffolding of construction every day, and should be able to find hidden safety hazards in construction at any time and be able to point out adjustments and changes in a timely manner to ensure the safety of construction;

How did the scaffolding get its name?

Scaffold refers to various supports erected on the construction site for workers to operate and handle vertical and horizontal transportation, mainly for the construction workers to work up and down or for the enclosure of peripheral safety nets and high-altitude device components. To put it bluntly, it is to build a scaffold, which is convenient for construction workers to use all four limbs, and it is convenient to climb up and down, so it is called scaffolding. Compared with the general structure, the working conditions of scaffolding have the following characteristics: 1. The load is highly variable; 2. The joints connected by fasteners are classified as semi-rigid, and the rigidity of the joints is related to the quality of the fasteners and the quality of the device, and the function of the joints has great variation; 3. The scaffold structure and components have initial defects, such as the initial bending and corrosion of the rods, the erection size error, the load eccentricity, etc. are relatively large;

The overall effect of scaffolding is more stable

Scaffolding has a support system to ensure its stability in two directions perpendicular to each other. Before erecting, it must be laid out strictly according to the design requirements. During installation, it is required to add a horizontal tie rod of 48x3.5 steel pipe to fasten it every time a layer of gantry is installed. The support force of the scaffold mainly depends on the overall force of the support frame, and this overall effect should be exerted.

How to remedy the local deformation of the buckle scaffold

1. Local deformation of scaffolding caused by foundation settlement. During the construction process on the construction site, if the scaffold is deformed due to the settlement of the foundation, the foundation under the scaffold needs to be compacted first, and then the cross-section of the double-curved frame is erected on the cross-section of the double-curved frame. to the outer layer of the deformation zone. The constellation or scissor stand must be set on a solid and reliable foundation. 2. The deflection and deformation of the cantilever steel beam on which the scaffold is erected exceeds the specified value. The anchor points behind the cantilevered steel beams should be reinforced, and the steel beams should be fastened with steel supports and U-shaped brackets to bear the roof. There is a gap between the embedded steel ring and the steel beam, which must be fixed with horse wedges. Check the steel wire ropes at the outer ends of the hanging steel beams one by one, and tighten them all to ensure uniform stress.

How to make scaffolding safer?

1. Additional protective measures In the construction of high-rise buildings, the outer frame should be covered with bamboo slats or steel mesh at every step of the operation, and a 1m-high railing and bamboo slats should be set up on the outside. On the outside of the scaffold, set up a safety net. 2. Floor protection measures Concrete frame projects are now common, and they generally use steel tubes to support steel formwork construction. In order to do a good job in the protection of floor construction, floor guards can be used. The guard frame is equivalent to the height of two floors of the building, and the width of the guard frame is equivalent to the length of one bay of the building. 3. Protective measures for floor inclined racks In some concrete frame high-rise buildings, due to insufficient lifting equipment, it is inconvenient to install floor guards, so steel formwork is used to support them. It is best to set up an inclined cantilever around the building, the vertical height is the same as the height of the construction building, and a large crossbar is erected on the cantilever to pull the safety net diagonally.

How to understand the use of aluminum alloy scaffolding

Through understanding, it can be seen that the current aluminum alloy scaffolding, with the actual advantages of basic materials, can play a practical role in different construction fields. During the use and transportation of scaffolding, due to the relatively light aluminum alloy material, reducing It reduces the workload of personnel in the process of handling and installation, and can be quickly installed and used, thereby improving labor and construction efficiency. At present, aluminum alloy scaffolding is widely used, which involves many different applications such as construction, decoration, decoration, and industry. Application fields, and in practical applications, the product advantages of aluminum alloy scaffolding can be exerted. In the actual understanding process, due to the very reasonable design structure of aluminum alloy scaffolding, in the process of use, it has the advantages of high strength, good stability, anti-corrosion and easy installation, and in the process of handling and storage, not only improves the The transportation efficiency is improved, and the storage space can be effectively saved during the storage process, and the corrosion and rust problems of the scaffolding can be reduced under a certain storage environment.
