Description

Technical Field

[0001] This utility model relates to the field of prefabricated column technology, specifically a prefabricated column. Background Technology

[0002] Prefabricated columns are a key component in prefabricated building systems. They refer to column structures that are prefabricated in a factory and quickly assembled on the construction site using standardized joints. They are an alternative to traditional cast-in-place concrete columns, featuring modular design, factory production, and efficient installation, and are widely used in industrial plants, residential buildings, bridge engineering, and other fields. Based on the above, the following problems were found: After the prefabricated columns are hoisted to the designated area, it is necessary to ensure that the main body is installed vertically. This requires the use of jacks and temporary shims for leveling. Only after leveling can subsequent grouting be carried out. However, the columns themselves are heavy, making the leveling process difficult and cumbersome, and inconvenient to use.

[0003] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a prefabricated column in order to achieve a more practical purpose. Utility Model Content

[0004] The purpose of this invention is to provide a prefabricated column to solve the problems mentioned in the background art.

A guide groove is opened on the inner side of the guide frame. The positioning component includes a positioning plate. A fixing hole is opened on the outer side of the positioning plate. A reserved rib is inserted inside the fixing hole. A guide block is fixedly installed on the middle of the top end of the positioning plate. The top end of the guide block has a four-sided pyramidal structure, and the outer side of the bottom end of the guide block fits against the guide groove.

[0006] By adopting the above technical solution, the positioning components facilitate the guidance and fixed installation of precast column components. The hollow structure of the column body allows for lightweighting and improved construction efficiency while ensuring structural performance. The guide frame facilitates the installation of the precast column components, improving installation efficiency. The fixing holes allow for easy fitting onto the outside of the building's reserved reinforcement bars, thus fixing the positioning plate. The positioning plate itself is small in size and relatively lightweight, allowing for easy adjustment of its installation position, making it easy to level. The four-sided pyramidal structure at the top of the guide block facilitates easy insertion into the guide frame for guidance, ensuring the precast column component is accurately placed on top of the positioning plate. The horizontal setting of the positioning plate ensures the column remains vertical, avoiding the need for subsequent leveling and improving efficiency.

[0007] Furthermore, the column body is internally embedded with several reinforcing steel bars, and several stirrups are fixedly installed on the outside of the reinforcing steel bars.

[0008] By adopting the above technical solution, the arrangement of the skeleton steel bars and stirrups facilitates the fixing of the skeleton steel bars into a cage structure by the stirrups, which is beneficial to improving the compressive and shear resistance of the column.

[0009] Furthermore, a lifting bar is provided on the inner side of the top of the column, and the lifting bar is fixedly connected to the adjacent stirrup.

[0010] By adopting the above technical solution and setting up the lifting ribs, it is easy to set up a stable lifting ring at the top of the column, which facilitates lifting and ensures balance during the lifting process.

[0011] Furthermore, a grouting cylinder is fixedly installed on the outer side of the bottom end of the skeleton steel bar, and the grouting cylinder is sleeved on the outside of the reserved steel bar.

[0012] By adopting the above technical solution, the grouting cylinder facilitates the injection of grout into the interior. After the grout solidifies, it forms a high-strength connection, thus achieving a stable and fixed connection between the device and the building.

[0013] Furthermore, the bottom of one side of the grouting cylinder is provided with a grouting port, and the top of one side of the grouting cylinder is provided with a grout outlet.

[0014] By adopting the above technical solution, the setting of the grouting port and the grout outlet facilitates the injection of grout from the bottom into the grouting cylinder, and the grout fills the cavity inside the grouting cylinder from bottom to top, avoiding the formation of voids.

[0015] Furthermore, both the grouting port and the grout outlet are located on the outside of the column.

[0016] By adopting the above technical solution, with both the grouting port and the grout outlet located on the outside of the column, it is convenient to use grouting equipment to inject grout into the grouting cylinder.

[0017] Furthermore, a mounting ear is fixedly installed on the outer side of the bottom end of the guide frame, and a mounting hole is opened on the surface of the mounting ear. The mounting hole is fixedly installed on the outer side of the bottom end of the grouting cylinder.

[0018] By adopting the above technical solution and installing the ear, it is easy to position the guide frame and the grouting cylinder, which facilitates the accurate casting of the column and ensures structural precision.

[0019] Compared with existing technologies, the beneficial effects of this utility model are as follows: The positioning components facilitate the guidance and fixed installation of precast column components; the hollow structure of the column body facilitates lightweighting and improved construction efficiency while ensuring structural performance; the guide frame facilitates the guidance of the precast column component installation, improving installation efficiency; the fixing holes facilitate fitting onto the outside of the building's reserved reinforcement bars to fix the positioning plate; the positioning plate itself is small in size and relatively lightweight, allowing for easy adjustment of its installation position, thus facilitating leveling; the four-sided pyramidal structure at the top of the guide block allows for easy insertion into the guide frame for guidance, ensuring precise placement of the precast column component on top of the positioning plate; the horizontal setting of the positioning plate ensures the column remains vertical, avoiding subsequent leveling processes and improving efficiency. This utility model facilitates convenient positioning and installation of columns, ensuring their verticality and effectively improving work efficiency, thus possessing high practical value.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a prefabricated column, including a prefabricated column assembly 1. The prefabricated column assembly 1 has a positioning component 2 at its bottom. The positioning component 2 facilitates guiding and fixing the prefabricated column assembly 1. The prefabricated column assembly 1 includes a column body 11, which has a hollow structure. This hollow structure facilitates lightweighting and improved construction efficiency while ensuring structural performance. A guide frame 18 is fixedly installed on the inner side of the bottom end of the column body 11. The guide frame 18 facilitates guiding the installation of the prefabricated column assembly 1, improving installation efficiency. A guide groove 111 is provided on the inner side of the guide frame 18. The positioning component 2 includes a positioning plate 21, and a fixing hole 24 is provided on the outer side of the positioning plate 21. The fixing hole 24 facilitates... The positioning plate 21 is fixed to the outside of the pre-reserved reinforcement 23. The positioning plate 21 is small in size and relatively light in weight, and its installation position can be easily adjusted to make it level. The pre-reserved reinforcement 23 is inserted into the fixing hole 24. A guide block 22 is fixedly installed at the top center of the positioning plate 21. The top of the guide block 22 is a four-sided pyramid structure, and the outer side of the bottom of the guide block 22 fits into the guide groove 111. The four-sided pyramid structure of the top of the guide block 22 makes it easy to insert the guide block 22 into the guide frame 18 for guidance, so that the precast column assembly 1 can be accurately placed on the top of the positioning plate 21. The horizontal setting of the positioning plate 21 can ensure that the column 11 remains vertical, avoiding the subsequent leveling process and improving efficiency.

[0024] The column 11 has several reinforcing steel bars 12 embedded inside, and several stirrups 14 are fixedly installed on the outside of the reinforcing steel bars 12. The setting of the reinforcing steel bars 12 and the stirrups 14 makes it easy for the stirrups 14 to fix the reinforcing steel bars 12 into a cage structure, which is beneficial to improving the compressive and shear resistance of the column 11.

[0025] The column 11 has a lifting rib 13 on the inner side of the top end. The lifting rib 13 is fixedly connected to the adjacent stirrup 14. The setting of the lifting rib 13 makes it easy to set a stable lifting ring at the top end of the column 11, which facilitates the lifting and ensures the balance during the lifting process.

[0026] Among them, a grouting cylinder 15 is fixedly installed on the outer side of the bottom end of the skeleton steel bar 12, and the grouting cylinder 15 is sleeved on the outer side of the reserved steel bar 23. The setting of the grouting cylinder 15 makes it easy to inject grout inside. After the grout solidifies, it forms a high-strength connection, realizing a stable fixed connection between the device and the building.

[0027] The grouting cylinder 15 has a grouting port 16 at the bottom of one side and a grouting outlet 17 at the top of one side. The grouting port 16 and the grouting outlet 17 facilitate the injection of grout from the bottom into the grouting cylinder 15, and the grout fills the cavity inside the grouting cylinder 15 from bottom to top, thus avoiding the formation of voids.

[0028] The grouting port 16 and the grouting outlet 17 are both located on the outside of the column 11. The fact that the grouting port 16 and the grouting outlet 17 are both located on the outside of the column 11 makes it convenient to use grouting equipment to inject grout into the grouting cylinder 15.

[0029] Among them, the guide frame 18 is fixedly installed with an installation ear 19 on the outer side of the bottom end. The installation ear 19 has an installation hole 110 on its surface. The installation hole 110 is fixedly installed on the outer side of the bottom end of the grouting cylinder 15. The installation ear 19 facilitates the positioning of the guide frame 18 and the grouting cylinder 15, and ensures the structural accuracy when the column 11 is cast.

[0030] Specifically, the working principle of this type of prefabricated column is as follows: During use, the installation of the reinforcing steel bars 12 and stirrups 14 facilitates the fixing of the reinforcing steel bars 12 into a cage-like structure by the stirrups 14, which improves the compressive and shear resistance of the column 11. The installation of the lifting bars 13 facilitates the installation of a stable lifting ring at the top of the column 11, making lifting easier and ensuring balance during the lifting process. The installation ears 19 facilitate the positioning of the guide frame 18 and the grouting cylinder 15, ensuring structural accuracy during the casting of the column 11. The hollow structure of the column 11 facilitates lightweighting and improved construction efficiency while maintaining structural performance. The guide frame 18 facilitates the guidance of the installation of the prefabricated column assembly 1, improving installation efficiency. The fixing holes 24 facilitate the fitting onto the outside of the pre-reserved reinforcing bars 23, thus fixing the positioning plate 21. The positioning plate 21 itself has a small volume... Small and relatively lightweight, the positioning plate 21 can be easily adjusted to a horizontal position. The guide block 22 has a four-sided pyramidal structure at its top, which facilitates easy insertion into the guide frame 18 for guidance, allowing the precast column assembly 1 to be accurately placed on top of the positioning plate 21. The horizontal setting of the positioning plate 21 ensures that the column 11 remains vertical, avoiding the need for subsequent leveling and improving efficiency. The grouting cylinder 15 facilitates the injection of grout inside, and after the grout solidifies, it forms a high-strength connection, achieving a stable connection between the device and the building. The grouting port 16 and the grouting outlet 17 facilitate the injection of grout from the bottom into the grouting cylinder 15, filling the cavity inside the grouting cylinder 15 from bottom to top, avoiding the formation of voids. The grouting port 16 and the grouting outlet 17 are both located on the outside of the column 11, facilitating the use of grouting equipment to inject grout into the grouting cylinder 15.
