Description

Technical Field

[0002] Prefabricated concrete buildings refer to concrete structures designed and constructed mainly with factory-produced prefabricated reinforced concrete components through on-site assembly. They are generally divided into two categories: fully assembled buildings and partially assembled buildings. Fully assembled buildings are generally low-rise or multi-story buildings with low seismic fortification requirements. The main components of partially assembled buildings are generally prefabricated components, which are connected on-site through cast-in-place concrete to form an assembled integral structure. The characteristics of this building are fast construction speed, convenient for winter construction, high production efficiency, good product quality, and reduced material loss.

[0003] Most of the stairs in the house are installed by splicing prefabricated parts, which saves a lot of time compared to the on-site manufacturing method. The installation method of prefabricated parts is to lift the prefabricated concrete parts of the stairs prefabricated in the factory to the installation site, and then align the installation line so that the embedded steel bars are inserted into the pin key holes. However, the weight of a section of concrete prefabricated parts for stairs is usually around two or three tons, which has high requirements on the model of the lifting device, and the transportation is also more troublesome, which needs to be improved.
