Detailed Description
The utility model is described in further detail below with reference to fig. 1-3.
Examples
At present, the temporary manned stairs are used as a manned channel, so that potential safety hazards of workers climbing the frame body or the reinforcing steel bars are avoided.
The temporary stairway in the scheme can be repeatedly used in the construction process, and the temporary stairway can be hoisted to another place for continuous use after the prefabricated stairway is hoisted.
As shown in fig. 1, 2 and 3, a liftable temporary stairway in an assembled structure comprises a bottom plate 3, a side frame 2, a lifting fixing beam 1 and supporting legs 4.
As shown in fig. 3, the bottom plate 3 has a rectangular planar frame structure, and the top surface of the bottom plate is provided with a antiskid plate.
The antiskid plate is a wood plate fixedly paved on the top surface of the bottom plate, a plurality of antiskid strips are fixedly arranged on the top surface of the wood plate, the antiskid strips are fixedly connected with the wood plate, and the antiskid strips are arranged on the top surface and the bottom surface of the wood plate.
The antiskid plate is a wood plate or a waste wood template, and after being cut into the size of a bottom plate 3, a plurality of equidistant antiskid strips 31 are arranged on the top surface of the wood plate;
the distance between the anti-slip strips 31 is 390mm, and the distance range is suitable for shorter people during walking.
Therefore, the requirements of higher and shorter people on the step can be met through the anti-slip strips 31 with the intervals, the step distance of the shorter people is usually about 390mm, the approximate range of the higher people is about 780mm, namely the shorter people can step in a single lattice, and the higher people can step in a double lattice.
As shown in fig. 1, the side frame 2 has a rectangular frame structure formed by square steel pipes, wherein, in order to ensure stability, a hand guard bar is arranged in the middle of the short side of the side frame to form the side frame 2 into a structure similar to a Chinese character 'mu', and a guard bar for preventing excessive foot span is also arranged between the middle hand guard bar and the bottom cross bar.
As shown in fig. 1 or fig. 2, a guard plate 21 is further disposed at a position near the bottom plate 3 at the bottom of the side frame 2, and the guard plate 21 is fixedly connected with the side frame 2, wherein the whole of the guard plate 21 is further coated with red and white stripes, so as to ensure that the edge position is more obvious, and prevent the situation of stepping on the air by mistake.
In order to ensure that the lifting is more convenient, a lifting fixing beam 1 is further arranged between the two side frames 2 and positioned at the top of the side frames 2, and two ends of the lifting fixing beam 1 are respectively fixedly connected with different side frames 2, so that the lifting is more convenient, and the effect of secondarily reinforcing the whole temporary stair is realized.
As preferable: in order to be able to better hoist temporary stairways for scheduling and stabilisation of their supporting structures, there are at least two or more hoist fixing beams 1.
