Description

Technical Field

[0001] This utility model relates to an assembled integral irregular steel cage composite shear wall, belonging to the field of modular integrated building production technology. Background Technology

[0002] Driven by the continuous upgrading of residents' quality of life, the functional requirements of buildings are evolving towards refinement and customization. In the process of modernization of the construction industry, the traditional extensive construction mode is undergoing a transformation towards an industrialized construction system. As an important technical path for new building industrialization, the composite slab concrete shear wall system, through the construction of standardized prefabricated component libraries and integrated installation processes, not only significantly reduces the amount of on-site formwork work, but also reduces the overall construction cycle by 25%-30% through process synergy optimization, fully aligning with the concept of green construction and the requirements of lean construction.

[0003] For example, utility model patent number 202021213141.9 discloses a T-shaped node structure for double-sided composite walls. It includes three double-sided composite walls connected in a T-shape; two first double-sided composite walls are joined in an I-shape, and a second double-sided composite wall is perpendicularly connected to the joined node; the first and second double-sided composite walls are used to pre-embed steel wire rope lock sleeves within the cast-in-place hollow cavity, with a total of three steel wire rope lock sleeves pre-embedded; the main body of each steel wire rope lock sleeve is a steel wire rope, with a loop component near the node.

[0004] While the aforementioned patents simplify reinforcement and joint details at connections to ensure structural safety, current technology is not comprehensive and has the following drawbacks: Traditional precast concrete shear wall components are too heavy, making hoisting difficult, resulting in slow installation speed, high installation difficulty, and inability to guarantee construction efficiency. Furthermore, smaller hoisting equipment cannot be selected to meet the requirements of better, faster, and more environmentally friendly construction.

[0005] To solve one of the above problems, there is an urgent need for a prefabricated monolithic irregular steel cage composite shear wall. Utility Model Content

[0006] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to facilitate on-site hoisting, and under the same conditions, to select smaller hoisting equipment, thereby meeting the requirements of better, faster, and more environmentally friendly construction. To this end, an assembled integral irregular steel cage composite shear wall is provided.

[0007] The assembled integral irregular steel cage composite shear wall of this utility model has an "L" or "T" shaped cross-section. Its features include: an irregular steel cage, with inner and outer leaf wall panels embedded in concrete on both sides; the inner and outer leaf wall panels are arranged opposite each other to form a cast-in-place cavity; the cast-in-place cavity is filled with poured concrete; steel tie bars are provided within the cast-in-place cavity; and lifting holes are provided through the two sets of wall panels.

[0008] The irregular steel cage described in this utility model is prefabricated in advance on an automated production line, and then the prefabricated outer leaf wall panel and the prefabricated inner leaf wall panel are produced by concrete pouring on a fixed mold. The prefabricated outer leaf wall panel and the prefabricated inner leaf wall panel form a cast-in-place cavity. The steel reinforcement tie bars tie the prefabricated leaf panels on both sides to form a whole, which improves the overall structural performance and shear resistance, and ensures safety and durability.

[0009] Furthermore, due to the presence of the cast-in-place cavity, the weight of the wall of the same width and height is about half that of ordinary shear walls. In addition, the optimized lifting holes make it easier to hoist on site. Under the same conditions, smaller hoisting equipment can be selected, which meets the requirements of better, faster and more environmentally friendly construction. It solves and optimizes the problem that the traditional precast concrete shear wall components are too heavy, resulting in slow installation speed, high installation difficulty and inability to guarantee construction efficiency.

[0010] This invention solves and optimizes the problem that traditional precast concrete shear wall components are too heavy, resulting in slow installation speed, high installation difficulty, and inability to guarantee construction efficiency.

[0012] Preferably, the outer leaf plate and the inner leaf plate have coaxially arranged lifting holes, and both the outer leaf plate and the inner leaf plate are provided with additional reinforcing bars to reinforce the lifting holes.

[0013] Preferably, the reinforcing mesh on one side of the long side of the L-shaped reinforcing cage is embedded in the concrete to form the outer leaf plate, the reinforcing mesh on the other side of the long side of the L-shaped reinforcing cage is embedded in the concrete to form the inner leaf plate, the reinforcing mesh on one side of the short side of the L-shaped reinforcing cage is embedded in the concrete to form the outer leaf short plate, the reinforcing mesh on the other side of the short side of the L-shaped reinforcing cage is embedded in the concrete to form the inner leaf segment plate, and the reinforcing tie bars are located in the cast-in-place cavity between the outer leaf plate and the inner leaf plate, and their two ends are respectively lapped on the reinforcing mesh on both sides of the long side of the L-shaped reinforcing cage.

[0014] During subsequent construction, reinforcing bars can be inserted into the cast-in-place cavity, followed by concrete pouring to connect the upper and lower walls into a single unit. This increases the interface surface for vertical connections in precast composite shear walls, resulting in a highly reliable connection method. Furthermore, because the dimensions within the cavity are significantly larger than the space required for inserting reinforcing bars, installation is easier. The larger cavity size facilitates observation, ensuring the grout fills the cavity completely and guaranteeing construction quality.
