An assembled staircase with adjustable inclination angle

Abstract

The invention provides an assembled type stairway with the inclination angle adjustable. The assembled type stairway comprises two stair beams, a support rod, multiple step plates, rotating shafts, supports, connecting rods, connecting pieces, a rotating handle, a brake disc, handrails and armrests; the supports are symmetrically fixed to the stair beams, every two rotating shafts are fixed to the two ends of the corresponding step plate and arranged on the corresponding support to form one step. Connection between the connecting rods and the steps and connection between the handrails and the armrests are both of a hinged structure, therefore, the stair steps, the handrails and the armrests all become an angle-variable structure, and the linkage effect can be achieved; inclination angle adjusting of the stairway can be achieved only by rotating the rotating handle connected to one rotating shaft, and the stairway can achieve the safe using function through fixing of a braking part. According to the assembled type stairway, standardized production can be achieved, the construction efficiency can be improved, and the materials and cost can be saved.

Description

technical field [0001] The invention belongs to the field of construction engineering and relates to an assembled staircase, in particular to an assembled staircase with flexible and convenient installation and adjustable inclination angle. Background technique [0002] During the construction of temporary simple houses or factory buildings on the construction site, it is usually necessary to build stairs. Existing simple housing stairs or stairs in factory buildings are usually cast-in-place and finished product assembly. Among them, the pouring-in-place method is used for construction, which has a long period, high cost, fixed structure, and is not easy to improve; the workflow of the finished assembled staircase is generally that the staircase manufacturer conducts a second deepening design according to the drawings provided by the design institute, processes the staircase components, and carries out The components are numbered, then transported to the site, and each com...

Problems solved by technology

Among them, the pouring-in-place method is used for construction, which has a long period, high cost, fixed structure, and is not easy to improve; the workflow of the finished assembled staircase is generally that the staircase manufacturer conducts a second deepening design according to the drawings provided by the design institute, processes the staircase components, and carries out The components are numbered, then transported to the site, and the components are welded or bolted to each other for assembly

However, during the installation process, there are often situations where the design drawings are different from the construction site. At this time, a certain step can only be raised, and the cost is exchanged for comfort; or the workers use wrenches and welding tools to cut or redesign the components. , not only delaying the construction period, but also causing a lot of waste; not only poor flexibility, but also inconvenient installation, resulting in low work efficiency
