Description

Technical Field

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

[0002] In the current field of industrialized building, reinforced concrete is widely used. The reason why steel bars and concrete, which have very different physical and mechanical properties, can be effectively combined and work together is mainly due to the bonding force between them. Precast frame columns are a new type of prefabricated structural component in the field of industrialized building. They are mainly used to replace traditional cast-in-place concrete columns or single precast columns, so as to achieve rapid construction and multi-functional integration.

[0003] For example, Chinese patent application CN201320706210.3 discloses a precast frame column, including column keys and a steel reinforcement support frame. The column keys are formed by pouring concrete into the steel reinforcement frame. The column keys are inserted into the bottom of the steel reinforcement support frame and are also filled with concrete. The steel reinforcement support frame is arranged in a mesh pattern. The upper steel reinforcement of the support frame extends outward by 150mm, and the lower steel reinforcement extends outward by 100mm. The column keys are 300mm high and 150mm in diameter, and are cylindrical or square. The beneficial effects of this utility model are: by installing column keys at the bottom of the reinforced concrete and extending steel reinforcement from the upper and lower ends of the steel reinforcement support frame, the connection of steel reinforcement between columns is made more convenient. Overall, the structural improvement of the precast frame column solves the problem of difficult construction of column steel reinforcement connection, and the overall seismic performance of the column is better; at the same time, the precast column reduces on-site "wet work," making the construction site cleaner and safer.

[0004] However, in actual use, when multiple of the above devices are needed to achieve splicing at different locations, the spliced ​​steel frame lacks support and assistance, which can easily lead to the collapse of the spliced ​​steel frame, affecting subsequent construction and thus having limitations. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a prefabricated frame column. By pushing the auxiliary connecting steel frame, a U-shaped fixed steel frame is driven to rise and fall along the main body of the frame column. This facilitates the contact between two connecting steel columns with the auxiliary connecting steel frame, helping the main body of the connected frame column to quickly align with the slot in the auxiliary connecting steel frame, reducing manual adjustment time, lowering the risk of misalignment, and thus facilitating auxiliary support for the main body of the connected frame column. This enables the splicing of multiple main body frames, improves the construction and use efficiency, and is convenient to use, effectively solving the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a prefabricated frame column, comprising a frame column body;

[0007] The frame column body is provided with connecting components on the outside to assist in supporting the frame column body that needs to be spliced.

[0008] The connecting assembly includes an auxiliary connecting steel frame, which has slots on all four sides. The top and bottom of the auxiliary connecting steel frame are fixed with U-shaped fixing steel frames. The U-shaped fixing steel frames are threaded with expansion bolts for fixing the frame column body and the auxiliary connecting steel frame, which facilitates moving the auxiliary connecting steel frame to different positions on the frame column body for splicing. Connecting steel columns are provided on both sides of the bottom of the auxiliary connecting steel frame.

[0009] Preferably, two opposing L-shaped connecting steel plates are fixedly provided on both sides of the bottom of the auxiliary connecting steel frame, and connecting steel columns are provided at the bottom of the two L-shaped connecting steel plates, so that the connecting steel columns can limit and support the position of the auxiliary connecting steel frame and improve the overall auxiliary support effect.

[0010] Preferably, the bottom of the connecting steel column is provided with two steel plates distributed front and back, and the steel plates are fixed to the ground to facilitate the limiting support of the angle of the connecting steel column.

[0011] Preferably, steel pipes are fixedly provided between the two L-shaped connecting steel plates and between the two steel plates.

[0012] Preferably, the top of the connecting steel column is rotatably mounted on the steel pipe between the two L-shaped connecting steel plates, and the bottom of the connecting steel column is rotatably mounted on the steel pipe between the two steel plates. This facilitates lifting the position of the auxiliary connecting steel frame, causing the top and bottom of the connecting steel column to rotate around the two steel pipes respectively, so that the bottom of the connecting steel column can easily contact the ground.

[0013] Preferably, the frame column body is fixed with several uniformly distributed vertically arranged supporting steel plates inside, and several uniformly distributed steel reinforcement skeletons are fixed between the supporting steel plates, which greatly enhances the load-bearing capacity of the frame column body, improves the overall seismic resistance and ductility, and ensures the reliability of construction. Concrete is poured between two adjacent supporting steel plates, and the cast-in-place concrete inside the frame column body fills the hollow part inside to form a solid cross section, which greatly improves the compressive and bending resistance, forms continuity with the cast-in-place joints of beams and slabs, and improves the seismic performance of the structure.

[0014] Compared with the prior art, this utility model provides a precast frame column with the following characteristics:

[0015] Beneficial effects:

[0016] This invention utilizes an auxiliary connecting steel frame to drive a U-shaped fixed steel frame to rise and fall along the main body of the frame column. This causes the top of the connecting steel column on one side of the bottom of the auxiliary connecting steel frame to rotate around the steel pipe between two L-shaped connecting steel plates, and the bottom of the connecting steel column to rotate around the steel pipe between the two steel plates. This supports the connecting steel column against the ground, facilitating contact between the two connecting steel columns and the auxiliary connecting steel frame. This allows the main body of the frame column to be connected to be inserted into the slot in the auxiliary connecting steel frame, helping to quickly align the main body of the frame column, reducing manual adjustment time, lowering the risk of misalignment, and facilitating auxiliary support for the main body of the frame column. This enables splicing between multiple main body frames, improves construction efficiency, and enhances ease of use. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5As shown, this utility model provides a precast frame column, including a frame column body 1. Several uniformly distributed vertically arranged supporting steel plates 4 are fixed inside the frame column body 1. Several uniformly distributed reinforcing steel skeletons 3 are fixed between the supporting steel plates 4, significantly enhancing the load-bearing capacity of the frame column body 1, improving overall seismic resistance and ductility, and ensuring construction reliability. Concrete 2 is poured between two adjacent supporting steel plates 4, and the cast-in-place concrete 2 fills the hollow part inside the frame column body 1, forming a solid cross-section, greatly improving compressive and bending resistance, forming continuity with the cast-in-place joints of beams and slabs, and improving the structural seismic performance.

[0026] like Figure 1-4 As shown, the frame column body 1 is provided with a connecting component 5 on its exterior for auxiliary support of the frame column body 1 that needs to be spliced. The connecting component 5 includes an auxiliary connecting steel frame 51. The auxiliary connecting steel frame 51 has slots on all four sides. The top and bottom of the auxiliary connecting steel frame 51 are fixed with U-shaped fixing steel frames 52, which facilitates pushing the auxiliary connecting steel frame 51 up and down along the frame column body 1 to achieve splicing at different positions. The U-shaped fixing steel frame 52 is threaded with expansion bolts 53 for fixing the frame column body 1 and the auxiliary connecting steel frame 51, which facilitates pushing the auxiliary connecting steel frame 51 to different positions on the frame column body 1 for splicing. The bottom two sides of the auxiliary connecting steel frame 51 are provided with connecting steel columns 57, and the bottom two sides of the auxiliary connecting steel frame 51 are fixed with two opposing L-shaped connecting steel plates 54.

[0027] The bottom of the two L-shaped connecting steel plates 54 is provided with connecting steel columns 57, which facilitates the limiting support of the position of the auxiliary connecting steel frame 51 by the connecting steel columns 57, thereby improving the overall auxiliary support effect. The bottom of the connecting steel column 57 is provided with two steel plates 55 distributed front and back, and the steel plates 55 are fixed to the ground, which facilitates the limiting support of the angle of the connecting steel column 57. Steel pipes 56 are fixed between the two L-shaped connecting steel plates 54 and between the two steel plates 55. The top of the connecting steel column 57 is rotatably mounted on the steel pipe 56 between the two L-shaped connecting steel plates 54, and the bottom of the connecting steel column 57 is rotatably mounted on the steel pipe 56 between the two steel plates 55, which facilitates the lifting of the position of the auxiliary connecting steel frame 51 and drives the top and bottom of the connecting steel column 57 to rotate around the two steel pipes 56 respectively, so that the bottom of the connecting steel column 57 can touch the ground.

[0028] By setting the connecting component 5, when it is necessary to connect to any position on the frame column body 1, the expansion bolts 53 on the U-shaped fixed steel frame 52 are tightened, pushing the auxiliary connecting steel frame 51 to drive the U-shaped fixed steel frame 52 to rise and fall along the frame column body 1. After moving to the appropriate position, several expansion bolts 53 are tightened to fix the auxiliary connecting steel frame 51 to the frame column body 1. At the same time, the top of the connecting steel column 57 on the bottom side of the auxiliary connecting steel frame 51 rotates around the steel pipe 56 between the two L-shaped connecting steel plates 54, and the bottom of the connecting steel column 57 rotates around the steel pipe 56 between the two steel plates 55. The connecting steel column 57 is supported against the ground, and the two steel plates 55 are then cast and fixed, which greatly improves the compressive and bending resistance of the connecting steel column 57, prevents the frame column body 1 from overturning, and reduces the risk. This makes it easier for the two connecting steel columns 57 to abut against the auxiliary connecting steel frame 51, so that the frame column body 1 to be connected can be inserted into the slot in the auxiliary connecting steel frame 51, which helps the connected frame column body 1 to be quickly aligned, reduces manual adjustment time, reduces the risk of misalignment, and facilitates the auxiliary support of the connected frame column body 1, realizes the splicing between multiple frame column bodies 1, improves the construction effect, and facilitates use.
