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

Embodiment 1

[0044] In a typical implementation of the present application, such as figure 1 As shown, on the basis of summarizing the application status of domestic prefabricated wall panels, the present invention proposes a prefabricated large slab filled wall concrete structure system and construction method:

[0045] 1. First, carry out the installation and construction of the prefabricated large slab filling wall 1;

[0046] 2. Temporarily fix and support the prefabricated large slab infill wall 1 after it is in place, and reserve a gap of 50-200mm between the top surface of the infill wall and the bottom surface of the cast-in-place concrete main structure 2 components according to the formwork requirements used in the project;

[0047] 3. Bind the steel bars of the main structure, and support the formwork and formwork support 10 of the main structure shear walls, columns, beams, floors and other components, and carry out the pouring construction of the concrete main structure 2;

Embodiment 2

[0053] The difference between this embodiment and embodiment 1 is that the connection between the side of the prefabricated filled large wall panel and the main structure of cast-in-place concrete is different, and the rest of the methods are exactly the same as the embodiment, specifically as figure 2 , Figure 4 and Figure 5 shown;

[0054] Reasonable and reliable connection between the prefabricated large slab wall and the main structure is the key to the successful application of the prefabricated and filled large wall slab concrete structure construction technology; The connection also proposes another connection method. This connection must not only ensure the effective connection between the wall and the main structure, and the wall will not collapse under the action of the earthquake, but also ensure that the concrete structure bears all the loads, and the wall does not participate in bearing the vertical load. loads and horizontal loads; for specific connection me...

Embodiment 3

[0058] The difference between this embodiment and embodiment 1 lies in the connection between the side of the prefabricated filled large wall panel and the main structure of cast-in-place concrete, and the rest of the methods are completely the same as embodiment 1.

[0059] Reasonable and reliable connection between the prefabricated large slab wall and the main structure is the key to the successful application of the prefabricated and filled large wall slab concrete structure construction technology; The connection also proposes another connection method. This connection must not only ensure the effective connection between the wall and the main structure, and the wall will not collapse under the action of the earthquake, but also ensure that the concrete structure bears all the loads, and the wall does not participate in bearing the vertical load. loads and horizontal loads; for specific connection methods, see image 3 , Figure 4 and Figure 5 ;

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...
