Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a prefabricated assembly structure for structural columns. Background Technology

[0002] To enhance the overall integrity and stability of buildings, reinforced concrete structural columns should be installed in the walls of multi-story brick-concrete structures and connected to the ring beams of each floor to form a spatial frame capable of resisting bending and shear. Structural columns are an effective measure to prevent building collapse. Structural columns are typically placed at the four corners of exterior walls, at the intersection of transverse and longitudinal walls in staggered floor areas, on both sides of large openings, and at the intersection of interior and exterior walls in large rooms. Furthermore, the requirements for the placement of structural columns vary depending on the number of stories and the earthquake intensity.

[0003] Traditional construction of structural columns mostly employs on-site casting, which suffers from problems such as long construction cycles, significant material waste, high skill requirements for workers, and substantial on-site environmental pollution. In recent years, with the rapid development of prefabricated building technology, prefabricated structural columns have gradually gained attention. However, existing prefabricated structural columns still suffer from problems such as unreliable connections, inaccurate positioning, and low installation efficiency during the assembly process. Utility Model Content

[0004] To address or partially address the problems existing in related technologies, this application provides a prefabricated assembly structure for structural columns, which achieves rapid, accurate, and reliable installation of structural columns through standardized prefabricated components and innovative assembly technology.

[0005] The first aspect of this application provides a prefabricated assembly structure for a structural column, comprising: a prefabricated structural column, a first embedded plate embedded at the bottom of the prefabricated structural column, a connector disposed at the bottom of the first embedded plate, a prefabricated composite slab connected to the first embedded plate based on the connector, a second embedded plate connected to the first embedded plate and embedded in the floor structure, and a concrete layer poured on the upper part of the prefabricated composite slab.

[0006] Among them, the connector is an L-shaped component, and four L-shaped components are provided at the bottom of the first embedded plate, which are stably connected to the precast composite plate based on the L-shaped components.

[0007] When the precast structural columns are installed at the designed locations in the floor structure, the maximum error in the verticality and horizontal position of the precast structural columns shall not exceed 2mm.

[0008] Among them, the precast structural columns are made using high-precision molds in the prefabrication plant to ensure dimensional accuracy.

[0009] The technical solution provided in this application may include the following beneficial effects: This application provides a prefabricated assembly structure for structural columns, employing advanced prefabrication and assembly technology to achieve rapid installation and efficient construction. The required materials are widely available, effectively reducing the construction cost of the structural columns. The assembly process of the prefabricated structural columns is simple and quick, significantly shortening the construction cycle. Disassembly and material recycling are also very convenient, aligning with the principles of green building. Verified through multiple engineering practices, this technology is stable and reliable, effectively improving the overall performance of the building structure, ensuring construction safety and quality, and reducing the impact on the surrounding environment of the construction site.

[0018] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0019] like Figures 1-3 The prefabricated assembly structure of the structural column includes: a prefabricated structural column 1, a first embedded plate 2 embedded at the bottom of the prefabricated structural column 1, a connector disposed at the bottom of the first embedded plate 2, a prefabricated composite slab 5 connected to the first embedded plate 2 based on the connector, a second embedded plate 4 connected to the first embedded plate 2 and embedded at the floor structure 8, and a concrete layer 7 poured on the top of the prefabricated composite slab 5.

[0020] The installation process for this application: Precast structural column 1 is fabricated in the precast factory. During the fabrication process, high-precision molds are prepared strictly according to the dimensions of precast structural column 1. The molds undergo rigorous inspection to ensure they are free from deformation and cracks. The spacing and quantity of reinforcing bars strictly adhere to... Figures 1-3 Configure it.

[0021] Pre-embedded steel plates are installed at the bottom of the precast structural column 1 and at the location of the floor structure 8. The first pre-embedded plate 2 is connected to the precast composite slab 5. The first pre-embedded plate 2 is equipped with four "L"-shaped steel bars to enhance the connection stability with the precast composite slab 5. During connection, the first pre-embedded plate 2 is precisely positioned onto the precast composite slab 5. In the prefabrication plant, high-precision molds and concrete blocks of appropriate strength are used to fix the position of the first pre-embedded plate 2 on the precast composite slab 5, such as... Figure 1 As shown, ensure the positional accuracy of the embedded steel plate 3. After the concrete is poured and cured, the assembly of the first embedded plate 2 and the precast composite slab 5 is hoisted to the corresponding floor structure 8.

[0022] At the construction site, the precast structural column 1 is hoisted to the designed position of the floor structure 8 and precisely positioned using measuring instruments to ensure that the maximum error in the verticality and horizontal position of the precast structural column 1 does not exceed 2mm.

[0023] Finally, high-precision welding technology is used to weld the first embedded plate 2 at the bottom of the precast structural column 1 and the second embedded plate 4 at the floor structure 8 to form a strong weld. The weld is tight and full. After the precast assembly and connection of the structural column is completed, concrete is poured to form a concrete layer 7 between the building surface layer 6 and the precast composite slab 5.
