Description

Technical Field

[0001] The utility model relates to the field of building stairs, in particular to an assembled building staircase. Background Art

[0002] Architectural stairs are components used for vertical transportation between floors in a building. They are used for transportation between floors and when there is a large height difference. Stairs should also be installed in multi-story and high-rise buildings that have elevators and escalators as the main means of vertical transportation.

[0003] Patent document publication number CN210857777U discloses an assembled building staircase, comprising a stair tread, a fixed base, a fixed plate, a first fixed column, a step fixing area, a second fixed column, a third fixed column, and a step. A fixed base in the horizontal direction is fixed to the right end of the stair tread, a fixed plate in the horizontal direction is fixed to the left end of the stair tread, three first fixed columns in the horizontal direction are equidistantly fixed to the left end of the fixed plate, a plurality of step fixing areas in the horizontal direction are opened at the upper end of the stair tread, and second fixed columns in the vertical direction are equidistantly fixed to the step fixing area, a plurality of third fixed columns in the horizontal direction are equidistantly fixed to the inner side of the left end of the stair tread, and the stair tread is fixed with steps in the vertical direction through the second fixed column and the third fixed column. The utility model has a simple construction method, a fast installation speed, and is extremely convenient to transport.

[0004] The above patent positions the stairs by means of fixed columns when in use. However, if the stair plates are supported only by fixed columns during use, the stair plates may slide due to long-term load bearing, and the stair plates may easily fall off. Therefore, we propose an assembled building staircase to solve the above problem. Utility Model Content

[0012] In a further embodiment, a foot pad is provided above the base, and the bottom surface of the foot pad is bonded to the upper surface of the base.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The device can connect floors by providing a stair connecting base plate, and the stair connecting base plate can be positioned in conjunction with the top seat and the base to prevent the stair connecting base plate from sliding. The positioning cylinder and the positioning rod can be used to preliminarily position the step plate to prevent the step plate from sliding, and the positioning strip can be used to position the step plate again to increase the stability of the step plate, thereby solving the problem that the step plate will slide due to long-term load-bearing when only relying on fixed columns to support the step plate, causing the step plate to fall off easily.
