Problems solved by technology
However, the existing prefabricated stairs are integral prefabricated parts, so the self-weight of the prefabricated stairs is relatively heavy. During the hoisting process, the weight of the prefabricated stairs is basically close to or even exceeds the maximum lifting weight allowed by the tower crane, which poses a great threat to the safe operation of the tower crane and has hidden dangers.
If you replace a larger tower crane, it will not only be very troublesome to replace, but also increase the construction cost

The invention discloses a splicable prefabricated stair and a using method thereof, and relates to the technical field of prefabricated stairs and using methods thereof. The splicable prefabricated stair comprises a stair frame, a step part, a fixing part, frame connecting parts, a first cross beam, a second cross beam, a handrail part, and a connecting part; a first hole is formed in the stair frame; the step part is arranged on the stair frame; a second hole is formed in the step part; the fixing part is arranged at one side of the stair frame; a fixing beam is arranged on the fixing part; afixing groove is formed in the upper surface of the fixing part; frame connecting parts are arranged at the two ends of the stair frame; a third hole and a fourth hole are formed in the frame connecting parts; the first cross beam is matched with the third hole, and the second cross beam is matched with the fourth hole; the frame connecting parts are connected with a wall surface through the first cross beam and the second cross beam; and the handrail part is arranged on the fixing part. According to the splicable prefabricated stair and the using method thereof, all components are disassembled, the mass of all the parts during installation is reduced, the safety of the installation process is guaranteed, and a plurality of sections of stairs on an upper layer and a lower layer can be spliced according to needs.
Description
technical field [0001] The present invention relates to the technical field of prefabricated stairs and its use method, in particular to a splicable prefabricated staircase and its use method. Background technique [0002] With the new trend of the construction industry developing towards prefabricated buildings, prefabricated stairs are the most mature components in prefabricated buildings. However, the existing prefabricated stairs are integral prefabricated parts, so the self-weight of the prefabricated stairs is relatively heavy. During the hoisting process, the weight of the prefabricated stairs is basically close to or even exceeds the maximum lifting weight allowed by the tower crane, which poses a great threat to the safe operation of the tower crane and has hidden dangers . If a larger tower crane is replaced, it will not only be very troublesome to replace, but also increase the construction cost. Contents of the invention [0003] In view of the above-mentione...
