Construction method and structure system of prefabricated large plate filled wall concrete structure

Abstract

The invention discloses a construction method and a structure system of a prefabricated large plate filled wall concrete structure. The prefabricated large plate filled wall concrete structure systemcomprises a cast-in-place concrete structure and a prefabricated large plate filled wall, the cast-in-place concrete structure comprises a cast-in-place concrete column, wall and beam, and the insideof the cast-in-place concrete structure is filled with the prefabricated large plate filled wall. The construction method includes the steps: firstly, mounting the prefabricated large plate filled wall serving as a peripheral protective wall and an inner wall on a certain layer of a building once, and reserving a gap between the top of the filled wall and the bottom of the cast-in-place concrete beam; secondly, setting templates such as a main structure concrete column, a shear wall, a beam and a floor slab and binding reinforcement, taking the side face of a wall plate as part of a wall column side template and pouring main structure concrete; finally, reliably connecting the top of the filled wall with the bottom of the concrete beam to reliably connect the filled wall with a cast-in-place concrete main structure. The technical problems of low construction speed, poor quality and integrity, difficulty in hoisting and the like of a prefabricated large plate filled wall in a traditional construction mode are solved.

Description

technical field [0001] The invention relates to a new concrete structure construction method, and specifically discloses a construction method and a structure system of a prefabricated large slab filled wall concrete structure. Background technique [0002] In reinforced concrete structures, especially in concrete frame structures, in order to meet building requirements such as space function separation and external enclosure, it is generally necessary to build infill walls in predetermined spans. For reinforced concrete structures, the conventional construction sequence is: first construct the main load-bearing structure, and after the structural concrete reaches the design strength, use aerated concrete blocks to build the filling wall. This traditional construction method has many disadvantages such as more wet work on site, slow construction speed, low efficiency, large amount of labor, great impact on the environment, and serious dust pollution, which is contrary to the...

Problems solved by technology

However, there are still two problems: 1) There are many joints on site, resulting in increased construction costs, and there is still room for improvement in construction efficiency; 2) The joints are easy to crack during use, and cracks in the outer wall will cause leakage problems. Affects the aesthetics and durability of the home

[0005] To sum up, the traditional masonry filling wall method is not in line with the development direction of green buildings due to the disadvantages of poor environmental performance, low construction efficiency, and poor integrity. At the same time, it is very prone to serious damage under the action of earthquakes

However, the strip-shaped prefabricated wall panels that are currently widely used also have problems such as high construction costs and poor performance.
