Abstract

The invention relates to the technical field of building stairs, in particular to a combined prefabricated stairway. The combined prefabricated stairway includes a prefabricated bottom board and a plurality of stepping blocks arranged on the prefabricated bottom board; and the prefabricated bottom board includes a plurality of clamping grooves formed in the prefabricated bottom board at intervals,the stepping blocks include stepping block bodies and clamping keys fixedly arranged on the lower parts of the stepping block bodies, lightening holes are formed in the stepping block bodies, and theclamping keys and the clamping grooves are installed in a matched mode. According to the combined prefabricated stairway, the problem that stairway board production and transportation costs are increased due to an overweight whole prefabricated stairway can be avoided, the connection structure is simple, transportation and hoisting construction are convenient, and the project cost is saved.

Description

technical field [0001] The invention relates to the technical field of building stairs, in particular to a combined prefabricated staircase. Background technique [0002] In the construction of stairs in the construction field, the stairs in the building are mainly cast-in-place or steel structures. The construction of cast-in-place stairs consumes a lot of resources such as formwork, scaffolding, energy and manpower, and the quality is uneven, and the construction progress is slow. , the construction period is long; the steel structure staircase technology is mature, but the noise generated during use is relatively large. It is generally used in industrial buildings such as factories, and civil buildings are less involved. At the same time, the cost is higher than that of concrete stairs. High degree, low production difficulty, convenient construction and installation have been widely used in the field of prefabricated buildings. [0003] The scissors ladder can also be ca...
