Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and in particular provides a fireproof bucket with a folding function for use on a construction site. Background Art
[0002] The fireproof bucket with folding function used on the construction site is a device made of galvanized steel plates, steel pipes, round steel, flat steel, damping hinges 5, rivets 8 and other hardware. It can effectively prevent sparks from flying during high-altitude or edge welding operations. It has the advantages of easy portability and flexible application. It is often used in welding operations at various stages of construction sites, including the main construction stage, the mechanical and electrical installation stage, and the outdoor curtain wall construction stage.
[0003] During the traditional reinforced concrete main body construction stage, the walls of each floor need to be pre-buried with casing, the adjacent ring beams need to be welded with equalizing rings, and the steel bars on the columns need to be welded with down conductors and various types of jumper grounding. When welding on the wall columns, it is often carried out at the same time as the full-floor scaffolding on the same floor. If the full-floor scaffolding is erected too quickly, it will squeeze out the space for placing fire buckets during welding operations, leaving welders with no space to place fire buckets during electric welding operations, and they can only allow sparks generated by electric welding to fly.
[0004] During traditional steel structure construction, the structural steel beams are often too flat and smooth to hang fire buckets, resulting in workers often not using fire buckets during electric welding operations during steel structure construction, or because the hook position of the fire bucket cannot be firmly fixed, the fire bucket often falls to the ground during use.
[0005] During electric welding construction, if the construction is carried out in a relatively narrow location, it is often inconvenient to put in or take out the fire bucket. When constructing in such a location, workers often take chances and no longer use the fire bucket.
[0006] Traditional fire buckets are large in shape, occupy too much space when stored in the warehouse, and are inconvenient to transport and move to the fire point. As a result, workers often ignore the use of fire buckets during electric welding construction, leading to repeated fire accidents at the construction site.
[0007] Traditional fire buckets are too large and are often lifted into place by a tower crane, which has lower construction efficiency than manual carrying.
[0008] Therefore, it is necessary to improve the adaptability of traditional fire buckets to the construction environment at each construction stage. Utility Model Content
