Detailed Description
The present application is described in further detail below with reference to the attached drawings.
The embodiment of the application discloses prefabricated temporary stair of going up people.
Referring to fig. 1, a prefabricated temporary stair for climbing includes a steel ladder 1 and a support frame 2 for supporting the steel ladder 1. Wherein the height of the steel ladder 1 is 3 meters to match the story height of most buildings. Meanwhile, the two sides of the steel ladder 1 are provided with the protective railings 11 so as to carry out safety protection on the steel ladder 1.
Referring to fig. 1, pedals 12 are fixedly connected to both ends of a steel ladder 1, and a pair of pedals 12 are horizontally arranged. Wherein the pedal 12 arranged at the upper end of the steel ladder 1 is used for abutting against the upper floor slab, and the pedal arranged at the lower end of the steel ladder 1 is used for abutting against the lower floor slab, so that the constructors can climb up conveniently.
Referring to fig. 1 and 2, the support frame 2 includes a pair of cross members 21 and a pair of first vertical members 22. The cross beam 21 includes a main beam 211 and an auxiliary beam 212, and both the main beam 211 and the auxiliary beam 212 are horizontally arranged and are parallel to the wall. The one end that girder 211 and auxiliary beam 212 are close to each other all link up and is provided with a plurality of connecting holes 23, and connecting hole 23 evenly sets up along the length direction of girder 211 and auxiliary beam 212, wears to be equipped with high strength bolt 24 in the connecting hole 23 to realize the stable connection of girder 211 and auxiliary beam 212, realize the regulation of girder 211 and the whole length of auxiliary beam 212 simultaneously, make the floor board that its adaptation span is different.
Therefore, when the length of the cross beam 21 is adjusted, the length of the cross beam 21 can be adjusted by only communicating the connecting holes 23 arranged on the auxiliary beam 212 with different connecting holes 23 arranged on the main beam 211 and then inserting the high-strength bolt 24 into the connecting holes 23, and the main beam 211 and the auxiliary beam 212 are stably connected.
Referring to fig. 1, an auxiliary plate 13 is hinged to one end of the pedal 12 far away from the steel ladder 1 through a hinge. Therefore, when the length of the cross beam 21 is adjusted, the auxiliary plate 13 can be used for continuously abutting against the floor plate, the phenomenon that a worker steps on the floor plate due to the fact that the gap between the pedal 12 and the floor plate is too large is avoided, and safety of constructors is guaranteed.
Referring to fig. 1, a pair of first vertical rods 22 are respectively arranged at one end of the pair of main beams 211 and distributed at two sides of the steel ladder 1, and the upper ends of the pair of first vertical rods 22 are fixedly connected with two sides of the upper end of the steel ladder 1.
Referring to fig. 3, a connecting rod 221 is horizontally disposed between the pair of first vertical rods 22, the connecting rod 221 is perpendicular to the pair of first vertical rods 22, and the connecting rod 221 is configured to abut against the pedal 12 to support the pedal 12. Meanwhile, the connecting rod 221 is provided with a plurality of reinforcing rods 2211 in an inclined upward direction, the reinforcing rods 2211 are uniformly distributed along the length direction of the connecting rod 221, the lower ends of the reinforcing rods 2211 are fixedly connected with the connecting rod 221, and the upper ends of the reinforcing rods 2211 are fixedly connected with the pedal 12, so that the pedal 12 is further supported, and the structural strength of the pedal 12 is improved.
Referring to fig. 1, a plurality of foundation beams 25 are horizontally arranged between the pair of main beams 211, the foundation beams 25 are perpendicular to the pair of main beams 211 and are uniformly distributed along the length direction of the pair of main beams 211, and two ends of the foundation beams 25 are respectively and fixedly connected with the pair of cross beams 21, so as to support and connect the pair of cross beams 21, thereby enhancing the structural stability of the support frame 2. Meanwhile, the two ends of the foundation beam 25 are vertically provided with the supporting rods 251, and the upper end and the lower end of each supporting rod 251 are fixedly connected with the foundation beam 25 and the steel ladder 1 respectively so as to stably support the steel ladder 1 and enhance the overall structural strength of the temporary stair.
Referring to fig. 1 and 4, a second vertical rod 27 is disposed at one end of each of the pair of main beams 211, which is far away from the pair of first vertical rods 22, and the lower end of the second vertical rod 27 is fixedly connected to the main beam 211. The anti-throwing vertical net 3 is horizontally arranged between the first vertical rod 22 and the second vertical rod 27, and two ends of the lower side of the anti-throwing vertical net 3 are respectively rotatably connected with the first vertical rod 22 and the second vertical rod 27. Meanwhile, pull rings 31 are arranged at two ends of the upper side of the anti-throwing vertical net 3, and hooks 32 for hooking the pull rings 31 tightly are arranged on the first vertical rod 22 and the second vertical rod 27.
Therefore, when the temporary stair for climbing people is hoisted, the anti-throwing standing net 3 is turned upwards to be in a vertical state, the hook 32 arranged on the first vertical rod 22 and the second vertical rod 27 is used for hooking the pull ring 31 arranged on the anti-throwing standing net 3, the anti-throwing standing net 3 is folded and stored, and the influence of the anti-throwing standing net 3 on the hoisting of the temporary stair for climbing people is avoided.
After the temporary stair climbing is installed on a construction floor, the hooks 32 arranged on the first vertical rod 22 and the second vertical rod 27 and the pull rings 31 arranged on the anti-throwing vertical net 3 are separated from each other, then the anti-throwing vertical net 3 is turned downwards to enable the anti-throwing vertical net 3 to be abutted to the wall bodies on two sides of the steel ladder 1, a stable triangular structure is formed, and therefore gaps between the steel ladder 1 and the wall bodies are blocked, constructors are avoided, and meanwhile the generation of high-altitude throwing objects can be avoided.
Referring to fig. 1, an auxiliary rod 271 is horizontally disposed between the pair of second vertical rods 27, and the auxiliary rod 271 is disposed at the upper ends of the pair of second vertical rods 27 and is disposed perpendicular to the pair of second vertical rods 27 to connect and support the pair of second vertical rods 27, thereby enhancing the structural strength thereof.
Referring to fig. 1, the upper ends of a pair of first vertical rods 22 and a pair of second vertical rods 27 are fixedly connected with hanging rings 4 so as to hoist the temporary stair.
The implementation principle of the prefabricated temporary stair of going up people of the embodiment of this application is: when the temporary stair is installed, firstly, the length of the cross beam 21 is adjusted to be in a proper state according to the span of the floor plates, then the prefabricated stair is hoisted to a specified floor by utilizing hoisting equipment, the cross beam 21 spans the floor plates on the same floor, the pedals 12 or the auxiliary plates 13 respectively abut against the floor plates on the upper floor and the lower floor, and finally the anti-throwing vertical net 3 is opened to abut against the wall bodies on two sides of the steel ladder 1, so that the temporary stair can be installed.
When this floor construction accomplished the construction, will prevent throwing and found net 3 and fold and accomodate, utilize hoisting equipment to hoist it once more to the last floor and install can.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
