The invention discloses an unbounded precast stair and a construction method thereof. The unbounded precast stair comprises frame assemblies, the frame assemblies comprise framed girders, framed girder plates and frame columns, a stair horse assembly is arranged between every two adjacent layers of frame assemblies, each stair horse assembly comprises a platform structure and a stair horse plate,and construction work is completed through the steps of foundation construction, frame column mounting, framed girder and the framed girder plate mounting, upper-layer frame column mounting, multilayer splicing, top sealing, stair horse assembly mounting and the like. The whole system is of a fabricated structure, a designed core component can be industrially produced in batches, unbounded splicing is conducted on a construction site, the traditional local pouring or mechanical connecting process after lapping of traditional precast joints is not needed, the construction period is greatly shortened, and the prefabricating type is made in the true sense; and construction is easy and convenient, the working period is short, environmental friendliness is achieved, overall performance is good,reliable safety is achieved, the practicability is high, and disassembled components can be repeatedly recycled.
Description
technical field [0001] The invention relates to the field of design and construction of prefabricated buildings, in particular to an unbonded prefabricated staircase and a construction method thereof. Background technique [0002] With the development of industrialization of building structures, prefabricated buildings have been widely used at home and abroad because of their simple construction, short construction period, low environmental pollution, and labor saving, and they are also the development trend of building structures. Among them, stairs are used for up and down traffic, and fire protection and escape routes are indispensable components in buildings. The application of prefabricated stairs can greatly shorten the construction period, and the quality is better guaranteed than cast-in-place stairs. [0003] Prefabricated stairs need to have sufficient passage width and evacuation capacity, and should meet the requirements of firmness, durability, safety, fire prev...
