Talking about the installation specification of the cantilever materials platform

[Summary description] There are more and more high-rise buildings in China, and cantilevered materials platforms are becoming more and more common. In practice, there have been many falling accidents from heights, and how to avoid such hidden dangers has become a hot issue. Therefore, it is particularly important to carry out relevant inspections during manufacturing and installation. In this regard, a list of inspection points for each part of the cantilever materials platform has been compiled for your understanding and reference.

Now there are more and more high-rise buildings in China, and cantilevered materials platforms are becoming more and more common. In practice, there have been many falling accidents from heights, and how to avoid such hidden dangers has become a hot issue. Therefore, it is particularly important to carry out relevant inspections during manufacturing and installation. In this regard, a list of inspection points for each part of the cantilever materials platform has been compiled for your understanding and reference.

1. Inspection points for the production of the cantilever materials platform:

For the materials platform manufactured on site or transferred from other places to the site, on-site inspection and acceptance shall be carried out. Forming platforms that do not meet the quality requirements will not be used. The inspection points are as follows:

1. Specifications and models of the main beam and the secondary beam. The main beam is 20# channel steel, and the secondary beam is 120#/140# channel steel;

2. Check the welding quality between the primary and secondary beams, between the baffle and the main beam, as well as the welding quality of the lifting ring, the cable-stayed ring and the main beam. The inspection requirements are: full welding, no welding defects, and a weld height of 10mm;

3. The specifications of the wire rope and the screw of the hanging basket of the materials platform should be checked, and the size of the platform and the structural dimensions of each part should also be checked.

Second, the installation inspection points of the cantilever materials platform

After the platform is installed in place, before it is put into use, the relevant quality supervision department should be established to check the installation of the cantilever materials platform; any installation that does not meet the relevant technical requirements should be re-installed until it meets the technical requirements. The installation and inspection points of the materials platform mainly come from the following six aspects:

1. Cable-pulling inspection: There are 2 main beams on each side of the cable-stayed wire rope, which must be in a taut and stressed state; about 125px of movable wire should be reserved for the basket bolt to prevent the basket bolt from slipping;

2. Check the baffle, the baffle should be close to the structural beam plate;

3. The protection inspection and safety protection of the materials platform must be strictly implemented in accordance with the safety standardization manual;

4. After the anchorage inspection, the number of pressure ring bars anchored on each side of the main beam should be 2, and the gap between the pressure ring bars and the main beam should be wedged with wooden wedges to ensure that the main beam is firmly anchored;

5. Check the load limit sign. The load limit sign should be hung in a conspicuous position and hung firmly;

6. Inspection of scaffolding laying, the laying of scaffolding should be safe and secure.

The installation specifications and precautions of the cantilever materials platform are as follows:

1. The platform should be manufactured by professional welders;

2. There is no de-soldering or missing welding in the weld, and the weld should be full;

3. The height of the protective railing shall not be lower than 1.5m, and the inner side shall be provided with a dense mesh net hanging vertically;

4. The anchor buckle of the wire rope should meet the requirements of the relevant specifications;

5. The boards on the platform should be fully paved, and 8 lead wires are tied;

6. Before installation, designate a special person to check whether the connection between the reserved anchor ring and the structure is reliable and whether there is looseness, and the installation can only be done after confirmation;

7. When hoisting the platform, the length of the four steel wire ropes used for hoisting should be the same. It is strictly forbidden to make one wire rope short and one long wire rope to ensure the smooth installation of the platform. In addition, the signal workers should keep close cooperation with the installation personnel to ensure safety;

8. For safety reasons, the platform should also hang obvious load-limiting cards, such as KG. When in use, a static load test should be carried out to confirm that there is no deformation of the material table, no cracks in the welds, and no cracks in the concrete at the anchor ring.

With all that said, do you now have a better understanding of the inspection points for each part of the overhanging materials platform? Therefore, whether it is before installation or use, it is necessary to carry out relevant inspections, do a good job of safety, and prevent problems before they occur.
