Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a standardized rapid access device based on prefabricated stairs. Background Technology

[0002] In prefabricated building construction, the main prefabricated concrete components currently involved are prefabricated composite slabs and prefabricated stairs. Because these components disrupt traditional construction processes, many on-site construction techniques remain to be explored. In actual construction, the hoisting of prefabricated stairs still faces several challenges. Due to the complexity and uncertainty of the main structure construction on-site, prefabricated stairs sometimes cannot be installed in time, preventing access to the working floor. This not only affects the construction progress but also poses a safety hazard to on-site workers. In traditional construction methods, workers typically need to use makeshift stairs on-site. These temporary stairs often lack sufficient safety measures, especially with large openings in the stairwells, which can easily lead to accidents. Therefore, ensuring that workers can safely and conveniently access the working floor has become a pressing issue in the field of prefabricated building construction. Summary of the Invention

Three fourth horizontal bars are welded from top to bottom to the lower part of the rear column, and the uppermost fourth horizontal bar corresponds to the first horizontal bar. A fifth horizontal bar corresponding to the third horizontal bar is welded to the two adjacent long front columns.

[0011] Specifically, the connecting frame includes four first connecting rods horizontally connected between the first and fourth horizontal rods, and two second connecting rods connected to the ends of the third and fifth horizontal rods. The first connecting rods correspond one-to-one with the front and rear columns.

The connecting frame 13 includes four first connecting rods 1301 horizontally connected between the first horizontal rod 1102 and the fourth horizontal rod 1203, and two second connecting rods 1302 connected to the ends of the third horizontal rod 1202 and the fifth horizontal rod 1104. The first connecting rods 1301 correspond one-to-one with the front column 1101 and the rear column 1201. A first diagonal rod 1303 is connected between the first connecting rod 1301 located at the edge and the bottom of the corresponding rear column 1201. A second diagonal rod 1304 corresponding to the rear column 1201 is connected between the first horizontal rod 1102 and the fourth horizontal rod 1203 located at the bottom. A third diagonal rod 1305 is connected between the rear end of the second connecting rod 1302 and the bottom of the corresponding front column 1101.

[0025] The components of the frame device 1 are connected by welding to each other, which ensures the stability of the frame, and the frame device 1 is placed directly on the concrete structure.

[0026] The support device 2 includes a steel plate platform 21 installed at the bottom outer sides of the front frame 11 and the rear frame 12. The bottom sides of the front frame 11 and the rear frame 12 are provided with diagonal supports 22 connected to the top of the steel plate platform 21. Specifically, the front steel plate platform 21 is welded to the first horizontal bar 1102, and the bottom of the rear column 1201 is welded to the rear steel plate platform 21. The support device 2 is used to improve the stability of the support.

[0027] The passageway device 3 includes two steel stair sections 31 that are staggered between the front frame 11 and the rear frame 12. Specifically, the two steel stair sections 31 are welded to both sides of the third horizontal bar 1202, with the bottom of the lower steel stair section 31 welded to the first horizontal bar 1102 and the top of the upper steel stair section 31 welded to the second horizontal bar 1103.
