Prefabricated reinforced concrete unit body for construction and method for building construction

Abstract

The invention relates to a prefabricated reinforced concrete unit body for construction and a method for building construction. The prefabricated reinforced concrete unit body is a unit body which consists of a bottom slab, a wall / column and an upper floor slab, and the bottom slab, the wall / column and the upper floor of the unit body are respectively provided with a drawing component for positioning and reinforced bar drawing. The construction of an integrated building can be realized through four steps, site assembly and prefabrication of each reinforced concrete unit body and each floor formed by assembling the unit bodies, design and installation of water, gas and power supply as well as ventilation systems, indoor decoration and outdoor decoration. The technique of the prefabricated reinforced concrete unit body can be easily mastered, thereby effectively reducing the personal safety risk of operators, facilitating the control of the engineering quality, and realizing the prompt inspection and replacement of unqualified products and the dual protection of floors. Moreover, the prefabricated reinforced concrete unit body can be repeatedly used after being removed, thereby reducing the construction waste and producing great significance in environmental protection.

Description

technical field [0001] The invention relates to a prefabricated reinforced concrete unit body for building and a method for constructing the building. Background technique [0002] At present, cast-in-place reinforced concrete foundations, columns, walls, beams, and slabs are commonly used in the construction of buildings as the main load-bearing structure. Or the outer enclosure mostly adopts masonry structure. This construction method has the following disadvantages: [0003] (1) The construction period of the whole building is long. [0004] (2) On-site operations are greatly affected by weather and other natural conditions. [0005] (3) The application degree of mechanization is low, and most of the processes rely on human manual work to complete, and the labor intensity is high. [0006] (4) The connection between each process is urgent, and the speed of the previous process affects the progress of the next process. [0007] (5) The quality of workers is uneven, la...

Problems solved by technology

[0003] (1) The construction period of the whole building is long

[0004] (2) On-site operations are greatly affected by weather and other natural conditions

[0005] (3) The application degree of mechanization is low, and most of the processes rely on human manual work to complete, and the labor intensity is high

[0007] (5) The quality of workers is uneven, labor intensity, multiple types of work, and multiple processes are blended together, which inevitably affects the quality of the project, and it is difficult to ensure the quality of the project

[0008] (6) The risk of on-site manual production is high, which directly threatens the life safety of workers

[0009] (7) The structural construction of each floor is irreversible, and the engineering quality of the next floor affects the structural safety and stability of the previous floor

[0010] (8) The singleness of the structural force often makes it difficult to ensure the overall safety of the building

[0011] (9) From the perspective of utilization, it is a one-time investment and cannot be reused. A large amount of construction waste will be generated during demolition, which will cause great pollution to the environment

[0012] (10) From the perspective of commodities, there is an unreasonable state of buying and selling, and it is difficult for the buyer to distinguish the quality and safety of the purchased house
