Description

Temporary stairway and installation method thereof Technical Field The invention belongs to the field of building construction, and particularly relates to a temporary stair and an installation method thereof. Background In the building construction project, according to the construction flow sequence, the stairs are under the floor, and then, there is a case that construction cannot be performed through the building stairs to the panel, and at this time, temporary stairs need to be erected. Most of the existing temporary stairways are simple and easy, have poor reliability, cannot be adjusted and circulated, and have various inconveniences and potential safety hazards. Disclosure of Invention The invention aims to provide a temporary stair and an installation method thereof, wherein the temporary stair is simple in structure, convenient to set up and disassemble, capable of being used in a turnover way, reliable in connection, capable of being adjusted tread and pedal height according to angles, and wide in application range. The technical scheme adopted by the invention is as follows: A temporary stair comprises two steel pipes which are arranged in parallel in an inclined mode, an adapter, a vertical rod and a cross rod are arranged along the two steel pipes in pairs, a main body of the adapter is a ring buckle, the ring buckle is detachably installed on the steel pipes, a screw rod is fixedly arranged on one side of the ring buckle, nuts are matched on the screw rod, screw rod holes are formed in one ends of the vertical rod and the cross rod, waist holes are formed in the other ends of the vertical rod and the cross rod, stair plates are arranged between two adjacent pairs of the adapter, at the installation position of each stair plate, the upper end of each stair plate is hinged with a screw rod on the upper layer through the screw rod holes and is clamped and connected with the waist holes of the cross rod through screw rods through screw rod assemblies, the screw rod holes of the cross rod are hinged with the screw rods on the lower layer and are prevented from falling through the nuts, at least two square tubes span and are connected to the cross rods on the two sides through metal wires, and the bottom surface of each stair plate is supported by screws or air nails and the back side faces are propped against the vertical rods on the two sides. Preferably, the stair tread comprises a tread and a riser. Preferably, the stair tread is plywood. Preferably, the maximum inclination angle of the steel pipe is 45 °. The method for installing the temporary stairway comprises the steps of firstly determining the overall height and the horizontal length of the temporary stairway according to the field environment, determining the number of stair plates, further determining the number of the transfer pieces, the vertical rods, the cross bars, the bolt assemblies and the square tubes, then installing the transfer pieces along the steel tubes, connecting the vertical rods and the cross bars on the transfer pieces along the steel tubes, then adjusting the transfer pieces to proper intervals and positions, fastening the transfer pieces, then connecting the vertical rods and the cross bars through the bolt assemblies, fastening the bolt assemblies after adjusting the cross bars to be horizontal, then transversely supporting the square tubes and connecting the square tubes to the cross bars on two sides through metal wires, and finally supporting the bottom surfaces of the stair plates and connecting the bottom surfaces of the square tubes to the vertical rods on two sides through screws or air nails. The beneficial effects of the invention are as follows: The temporary stair is simple in structure, convenient to set up and detach, capable of being used in a turnover mode, reliable in connection, capable of being adjusted tread and high in pedal according to angles, and wide in application range.
