Detailed Description

The invention is further described with reference to the accompanying drawings.

As shown in fig. 1-5, a retractable working floor pedestrian passageway is composed of an end-to-end module 1, a middle module 2, an end module 3 and a plank platform 4. The end-to-end module 1 can be inserted into the middle module 2, the middle module 2 can be inserted into the end module 3, the insertion length can be adjusted, and the thick wood board platform 4 is laid above a frame of the telescopic pedestrian passageway formed by the three modules.

The end-to-end module 1 consists of a first square steel main keel 101, a first square steel bracket 102 and a first square steel secondary keel 103. The middle module 2 is composed of a second square steel main keel 201 and a second square steel secondary keel 202. The end module comprises third party steel main joist 301, third party steel support 302 and third party steel secondary joist 303. The first, second and third steel main keels are two pieces of horizontally arranged square steel; the first, second and third square steel secondary keels are used as supports and are respectively arranged among the first, second and third square steel main keels; the first square steel support and the second square steel support are used as supporting legs and are respectively vertically arranged at the tail part of the end tail module and the end of the end module.

In foretell first side steel main joist 101 inserted second side steel main joist 201, during second side steel main joist 201 inserted third side steel main joist 301, can adjust whole length according to the on-the-spot demand during the use.

When in use, the first step: after the binding of the reinforcing steel bars at the lower part of the floor slab is finished, the retractable working layer pedestrian passageway is transported to a working surface;

step two: stretching out a pedestrian passageway of an operation layer according to the actual required length on site, wherein supporting legs of the passageway are required to be placed on a template, so that direct contact with floor slab reinforcing steel bars is avoided;

step three: a scaffold board or a wood board is laid on the channel cross bar, so that the walking of personnel is facilitated;

step four: and after the concrete pouring of the floor slab is finished, the pedestrian passageway is retracted and moved to the next working surface.

The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
