TECHNICAL FIELD
[0001] The utility model belongs to building stair technical field, concretely relates to a kind of assembled stair. BACKGROUND
[0002] The existing stair is designed as double-compartment steel beam bearing structure and suspended step form according to construction requirement, and the step two ends are supported by triangular rib plate welded on the steel beam, the tread can use stone, and the bottom surface is dark stainless steel metal finish and hides induction light belt, which presents the ingenious design that the step seems to be suspended on the steel beam and passes through glass guardrail.
[0003] The traditional stone step process of steel stair exposes many defects when facing such special structure, the traditional process usually carries out accurate line laying on site first, then welds prefabricated compartment step on the load-bearing steel beam, then encloses the steel step with finish, fixes glass guardrail on the side of step, and finally needs to additionally install a small section of "fake" step outside the glass guardrail to obtain the effect that the step visually extends outward through the glass. This process has the problem of low construction efficiency, because the on-site line laying, welding and other processes are complex and time-consuming, which leads to slow overall construction progress and high cost. If the construction period is to be ensured, a large amount of manpower is needed, and the quality is difficult to guarantee due to the uneven level of construction personnel. In addition, the cost is difficult to control due to material loss and cost accumulation caused by complex process. The precision is difficult to guarantee, and the on-site construction is interfered by many factors, so it is difficult to meet the high-precision installation requirements. Moreover, the on-site welding operation not only has great fire hazard, but also threatens the safety of personnel and property and the stability of building structure, and a large amount of construction waste is generated after construction, which has adverse effects on the environment, and it is very difficult to replace and maintain in the later period, so it is difficult to guarantee the consistency with the original step.
[0004] In summary, the traditional stone step process of steel stair is relatively complex, the on-site construction takes a long time, the cost is high, and the precision is difficult to guarantee, so technical improvement is urgently needed. UTILITY MODEL CONTENTS
