Specific implementation mode

[0033] To deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with implementation cases and drawings. The present utility model can be implemented in the following ways:

[0034] Refer to Figure 1-8 , an elevator shaft hollow building structure, including a number of telescopic cross - bars 1, pedal assemblies 2 and straight ladders 3 distributed in an array.

[0035] Among them, both ends of the telescopic cross - bar 1 extend to the building 4. The building 4 can be a load - bearing structure such as a wall or a structural column. Both ends of the telescopic cross - bar 1 can be fixedly connected to the building 4 by means of screws or the like. The telescopic cross - bar 1 includes an outer tube 11 and an inner tube 12 that can telescopically move within the outer tube 11. This design can adjust different lengths according to the site, and then lay the pedal assembly 2 on the telescopic cross - bar 1, eliminating the need to erect a scaffold, saving time and effort.

[0036] The described pedal assembly 2 is laid above the telescopic crossbar 1. The pedal assembly 2 includes at least one row of lid-lifting seamless pedals 21 and several rows of slotted pedals 22, and there is no gap between rows during splicing. Both ends of the lid-lifting seamless pedals 21 and the slotted pedals 22 are clamped on two adjacent telescopic crossbars 1. Two adjacent lid-lifting seamless pedals 21 and slotted pedals 22 in the same row are spliced without gaps through the horizontal head concave-convex design. Specifically, the lid-lifting seamless pedals 21 and the slotted pedals 22 include a support frame 23 and a pedal 24 arranged above the support frame 23. Anti-slip patterns 25 are provided on the surfaces of the lid-lifting seamless pedals 21 and the slotted pedals 22, which can play an anti-slip role. Hooks 26 for buckling on the telescopic crossbar 1 are provided at both ends of the support frame 23, and the hooks 26 at both ends of the support frame 23 are not in the same vertical plane. The number of hooks 26 at each end of the support frame 23 is two, which can make the entire pedal 24 more stable. One end of the pedal 24 extends outward with a connecting crosshead 241 for covering the hook 26. The free end of the connecting crosshead 241 protrudes outside the hook 26, and the installation direction is as Figure 4 shown by the arrow. The pedal 24 uses a design with one side fully enclosed and the other side open, so that two adjacent pedals 24 can be spliced without gaps, which can effectively prevent construction workers from falling, and greatly improves its safety performance.

[0037] A self-locking device 27 for locking the hook 26 on the telescopic crossbar 1 is provided on the side of the hook 26. The self-locking device 27 includes a limiting rod 271 and a movable arc-shaped lock piece 272 arranged on one side of the hook 26. A strip hole 273 for the limiting rod 271 to pass through is provided on the movable arc-shaped lock piece 272. The movable arc-shaped lock piece 272 can move on the limiting rod 271, and the length of the strip hole 273 is the moving range of the movable arc-shaped lock piece 272. After the hook 26 is buckled on the telescopic crossbar 1, sliding the movable arc-shaped lock piece 272 downward can prevent the hook 26 from detaching from the telescopic crossbar 1, and can prevent the safety hazard that the pedal 24 is lifted due to too strong high-altitude wind.

[0038] Referring to Figure 7 , the pedal 24 on the lid-lifting seamless pedal 21 includes two templates 242 hinged by a hinge 28. The straight ladder 3 is detachably arranged below the lid-lifting seamless pedal 21. The straight ladder 3 is an aluminum straight ladder, which is designed to be lightweight and convenient to pick up and place. When it is necessary to enter the elevator shaft, the template 242 of the lid-lifting seamless pedal 21 can be opened, and the straight ladder 3 can be placed in, and the upper end of the straight ladder 3 can be leaned against the template 242; when the construction workers do not need to enter the elevator shaft, the straight ladder 3 can be taken out and the lid-lifting seamless pedal 21 can be covered, and the operation is simple and fast, and the safety is high.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
