Super-high performance concrete frame structure fabricated building and construction method thereof

Abstract

The invention discloses a super-high performance concrete frame structure fabricated building and a construction method thereof. A splicing unit at least comprises beam, column and floor integrated pieces prefabricated by super-high performance concrete. The height of each column is the height of a building storey; the beams are perpendicular to the side walls of the columns; the floors are located on the upper surfaces of the beams; connecting parts are arranged on the side edges of the floors; and the two ends of the columns stretch out of the end faces of the floors and the beams. When fabricating is constructed, after the prefabricated integrated pieces adjacent to the building plane, the super-high performance concrete is poured into joints between the connecting parts of the side edges of the floors to enable the prefabricated integrated pieces to form a whole. The upper storey and the lower storey of the building are connected through the columns of the beam, column and floor integrated pieces. The prefabricated integrated pieces adopt the super-high performance concrete as structure materials, and the reasonable connecting arrangement is configured, so that the average thickness of the floor and the amount of connectors and the joints between prefabricated members both are decreased substantially. The self-weight of the building is reduced substantially under the premise of guaranteeing the rigidity and strength of the building, and construction difficulty is reduced.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a prefabricated building with an ultra-high performance concrete frame structure and a construction method thereof. Background technique [0002] Reinforced concrete prefabricated buildings have the advantages of saving formwork, fast construction progress, green environmental protection, etc., and are currently a building form that the country is vigorously developing. However, due to the low strength of ordinary concrete materials, the size of prefabricated components is limited, and there are a large number of joints between prefabricated components. The connections between joints have the disadvantages of complex reinforcement, difficult construction, and easy cracking. The limited size of prefabricated components also leads to poor integrity of the building, poor seismic performance, and a large number of joints and seams are not conducive to the waterproofing, heat p...

Problems solved by technology

However, due to the low strength of ordinary concrete materials, the size of prefabricated components is limited, and there are a large number of joints between prefabricated components. The connections between joints have the disadvantages of complex reinforcement, difficult construction, and easy cracking

The limited size of prefabricated components also leads to poor integrity of the building, poor seismic performance, and a large number of joints and seams are not conducive to the waterproofing, thermal insulation and heat insulation of the building

The low toughness of ordinary concrete also leads to low local strength of prefabricated components, which is easy to cause corner damage during demoulding, transportation and installation
