Abstract
Description
Technical Field
[0001] This application relates to the field of prefabricated component installation technology for buildings, and more particularly to a prefabricated component cavity column structure. Background Technology
[0002] With the rapid development of the modern construction industry, prefabricated buildings have gradually become the mainstream trend due to their high efficiency and environmental protection characteristics.
[0003] Traditional fixing methods typically rely on pre-set support points, which not only incurs significant labor costs but also prolongs the construction period, thus hindering project progress. Furthermore, as the proportion of prefabricated buildings continues to increase, the limitations of traditional fixing methods become increasingly apparent, urgently requiring more efficient alternatives to improve overall construction efficiency. Therefore, researching new fixing technologies and optimizing existing processes is of great significance for promoting the development of the prefabricated building industry.
[0004] Currently, the common fixing methods for both UHPC hollow columns and traditional precast PC columns mainly include two forms: pre-embedding support points in the floor slab and temporarily fixing the precast column by using two pairs of diagonal braces of different lengths on adjacent sides. While this method can ensure structural stability to a certain extent, it has significant drawbacks. First, pre-embedding support points requires additional time for planning and layout; second, adjusting the diagonal braces is complex, and they must remain stable throughout the entire concrete pouring process until the design strength is reached before removal. This results in a lengthy and cumbersome process chain, seriously affecting the overall project schedule. In addition, some construction sites adopt other simple reinforcement measures, such as steel wire rope binding or wooden wedge nesting, to assist in positioning. However, these methods often struggle to balance accuracy and safety, easily leading to subsequent quality problems.
[0005] The existing fixed method has two problems: first, the preliminary preparation work takes a lot of time, which increases unnecessary waiting time and manpower input; second, the temporary support device occupies a large area of the site, which is not conducive to on-site management and material transportation. Utility Model Content
[0006] In order to reduce the delays in construction processes caused by traditional fixing methods, shorten the construction cycle, reduce labor intensity, and avoid the waste of repeatedly building support systems, thereby effectively improving construction efficiency and saving costs, this application provides a precast component cavity column structure.
[0007] This application provides a precast component hollow column structure, which adopts the following technical solution:
[0008] A precast hollow column structure includes a template assembly, a beam bottom support assembly, and a slab bottom support assembly laid together, with reserved space for the hollow column. The structure comprises a first component, a second component, a third component, and a fourth component. The first, second, third, and fourth components are combined and connected to form a hollow column. Each of the first, second, third, and fourth components is provided with at least one set of support components. One end of each support component is inserted into the first component and / or the second component, and / or the third component, and / or the fourth component, and the other end is fixedly connected to the beam bottom support assembly and the slab bottom support assembly, respectively.
[0009] By adopting the above technical solution, rapid fixation of precast hollow columns on the construction site is achieved. Specifically, by combining the first, second, third, and fourth components into a hollow column and installing support components on it, these support components can be inserted at one end into different components of the hollow column and fixedly connected at the other end to existing beam bottom support components or slab bottom support components. This eliminates the need for traditional diagonal bracing and pre-embedded support points to effectively support and fix the hollow column. This not only simplifies the construction process and reduces waiting time between procedures but also significantly improves construction efficiency, reduces labor intensity, and ensures the stability and safety of the hollow column during installation.
[0010] Preferably, the first component, the second component, the third component and the fourth component are each provided with multiple sets of receiving parts, and one end of the supporting component is inserted into the receiving part.
[0011] By adopting the above technical solution, a more stable and flexible support effect can be achieved in precast cavity column structures. Specifically, multiple sets of receiving parts are set on the first, second, third, and fourth components, allowing the support components to be precisely inserted into these parts, thereby effectively improving the stability of the entire cavity column structure. At the same time, it allows the support components to select appropriate insertion positions according to actual needs, further improving the flexibility and convenience of the construction process, reducing the need for traditional diagonal bracing and pre-embedded support points, and helping to speed up the construction progress and reduce costs.
[0012] Preferably, the multiple sets of receiving parts on the first, second, third and fourth components are spaced 1 to 1.5 m apart.
[0013] By adopting the above technical solution, a reasonable layout of the components in the precast cavity column structure is achieved. Specifically, by setting multiple sets of receiving parts on the first, second, third, and fourth components at intervals of 1 to 1.5 meters, the stability and uniformity of the supporting components can be effectively guaranteed, thereby improving the overall stability of the entire cavity column structure.
[0014] Preferably, the support member includes a support body, a positioning part, and a holding part. The positioning part is fixed to one end of the support body, and one end of the positioning part is inserted into the receiving part. The holding part is fixed to the support body near the end of the positioning part.
[0015] By adopting the above technical solution, a stable connection between the supporting component and the hollow column is achieved. Specifically, the support body is precisely inserted into the receiving part through the positioning part, ensuring the effective fixation of the supporting component and the first, second, third, or fourth component of the hollow column, thereby improving the overall stability of the structure.
[0016] Preferably, the support member further includes a first adjusting part and a second adjusting part. One end of the first adjusting part is rotatably connected to the support body, and the other end is rotatably connected to the second adjusting part. One end of the second adjusting part is fixedly connected to the positioning part, and the other end is inserted into the first adjusting part.
[0017] By adopting the above technical solution, the adjustable length of the support component is achieved. Specifically, the rotatable connection and nested design between the first and second adjustment parts allow the support component to adjust its effective length according to the needs of different construction scenarios, thereby better adapting to the connection requirements between hollow columns of different sizes and the formwork support system.
[0018] Preferably, a support assembly is provided below the first frame. The support assembly is installed on a horizontal ground, and one end of the support assembly is connected to the first component, the second component, the third component and the fourth component respectively.
[0019] By adopting the above technical solution, the support components effectively enhance the stability of the bottom of the hollow column, preventing tilting or displacement due to uneven stress during installation. Simultaneously, the support components are installed on a level surface, further improving the overall structural stability and avoiding the complex procedures associated with traditional inclined support methods, thereby shortening the construction cycle and improving construction efficiency.
[0020] Preferably, the support assembly includes a first cover, a first side, a second cover, and a second side, with the two ends of the first cover connected to the first side and the second side, respectively, and the two ends of the second cover connected to the other ends of the first side and the second side, respectively.
[0021] By adopting the above technical solution, the support assembly consists of a first envelope, a first side, a second envelope, and a second side, with each part interconnected to form a stable support structure. This design effectively enhances the stability of the bottom of the precast component hollow column, preventing displacement or overturning during construction.

[0023] By adopting the above technical solution, the reinforcement effectively improves the overall stability and load-bearing capacity of the support assembly. Specifically, the reinforcement is located on the surfaces of the first envelope, the first side, the second envelope, and the second side, and is in contact with the horizontal ground. It can disperse the pressure from the cavity column, reduce local stress concentration, and thus prevent the support assembly from deforming or being damaged due to uneven stress.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] 1. By combining the supporting components with the existing floor slab formwork support system, there is no need to set up additional diagonal supports and pre-embedded support points, which simplifies the construction process, significantly shortens the waiting time for each process, and improves construction efficiency;

One end of the support member is inserted into the first to fourth members of the hollow column, and the other end is fixedly connected to the bottom support assembly of the beam or the bottom support assembly of the slab, which ensures the stability of the hollow column and avoids the impact of traditional fixing methods on the floor structure.
