Description

Technical Field

[0001] This invention belongs to the field of building construction, specifically relating to a temporary staircase and its installation method. Background Technology

[0002] In building construction projects, if the staircase is located beneath the floor slab according to the construction sequence, there are situations where it is impossible to reach the slab surface for construction using the building's staircase. In such cases, a temporary staircase needs to be erected. Currently, most temporary staircases are relatively simple, have poor reliability, and cannot be adjusted or reused, posing numerous inconveniences and safety hazards. Summary of the Invention

[0003] The purpose of this invention is to provide a temporary staircase and its installation method. The temporary staircase has a simple structure, is easy to assemble and disassemble, can be reused, has a reliable connection, and can adjust the tread width and tread height according to the angle, making it widely applicable.

[0004] The technical solution adopted in this invention is:

[0005] A temporary staircase includes two parallel, inclined steel pipes. The two pipes are equipped with a pair of adapters, vertical bars, and horizontal bars along their length. The adapter is a ring-shaped component, detachably mounted on the steel pipe. A screw is fixed to one side of the ring, and a nut fits on the screw. One end of the vertical bar and the horizontal bar have a screw hole, and the other end has a slotted hole. A stair tread is positioned between two adjacent pairs of adapters. At each stair tread's installation position, the upper end of the vertical bar is hinged to the upper screw through the screw hole and secured by a nut; the slotted hole at the lower end is clamped to the slotted hole of the horizontal bar via a bolt assembly. The screw hole of the horizontal bar is hinged to the lower screw and secured by a nut. At least two square tubes span across and are connected to the horizontal bars on both sides by metal wire. The bottom surface of the stair tread is supported and connected to the square tubes by screws or pneumatic nails, and its rear side abuts against the vertical bars on both sides.

[0006] Preferably, the stair tread includes a tread and a kick plate.

[0007] Preferably, the stair treads are made of plywood.

[0008] Preferably, the maximum inclination angle of the steel pipe is 45°.

[0009] The installation method for the temporary staircase is as follows: First, determine the overall height and horizontal length of the temporary staircase based on the site environment, determine the number of stair treads, and then determine the number of adapters, vertical bars, horizontal bars, bolt assemblies, and square tubes; then, install adapters along the steel pipe line, and connect vertical bars and horizontal bars to the adapters along the line; then, adjust each adapter to a suitable spacing and position, and tighten the adapters; then, connect the vertical bars and horizontal bars through the bolt assemblies, adjust the horizontal bars to be horizontal, and tighten the bolt assemblies; then, support the square tubes across and connect them to the horizontal bars on both sides with metal wires; finally, support the bottom surface of the stair treads and connect them to the square tubes with screws or pneumatic nails, with the back side abutting against the vertical bars on both sides.

[0010] The beneficial effects of this invention are:

[0011] This temporary staircase has a simple structure, is easy to assemble and disassemble, can be reused, has reliable connections, and can adjust the tread width and height according to the angle, making it suitable for a wide range of applications. Attached Figure Description
