Description

Technical Field

[0001] This utility model relates to the field of steel pipe column technology, and in particular to a wind-resistant and earthquake-resistant steel pipe column structure with reinforcing ribs. Background Technology

[0002] In construction engineering, concrete piles are commonly used as the supporting foundation for roads or bridges. In a building structure, piles are used to provide upward support, so the structural strength of the piles determines the stability of the road or bridge. Only by ensuring the structural stability of the piles can the building structure above be successfully constructed.

[0003] A search revealed a steel pipe for reinforcing concrete column pile structures (Authorization Announcement No.: CN 216108676U), which "comprising a steel pipe body inserted into a drilled hole in the column pile, with a gap between the steel pipe body and the drilled hole, and a plurality of grout outlet holes at the lower end of the steel pipe body. This utility model's steel pipe for reinforcing concrete column pile structures has grout outlet holes at the lower end of the steel pipe body, ensuring a grout outlet position between the bottom end of the steel pipe body and the bottom surface of the drilled hole in the column pile, thus increasing the grout outlet speed. Furthermore, the gap between the steel pipe body and the drilled hole ensures that the cement grout injected into the steel pipe flows smoothly to the outside of the steel pipe, allowing the inside and outside of the steel pipe to be encapsulated and solidified by the cement grout, achieving a firm bond between the steel pipe and the column pile, thereby strengthening the structural strength of the column pile."

[0004] Based on the aforementioned technologies, the applicant believes that most existing steel pipe columns are hollow and lack internal reinforcing ribs to strengthen their strength. As a result, they are prone to breakage when encountering strong winds or minor earthquakes. To address this issue, we have developed a wind-resistant and earthquake-resistant steel pipe column structure with reinforcing ribs. Utility Model Content

[0005] This utility model discloses a wind-resistant and earthquake-resistant steel pipe column structure with reinforcing ribs, aiming to solve the technical problem that most existing steel pipe columns are hollow and lack internal reinforcing ribs to strengthen the steel pipe column, making them prone to breakage when encountering strong winds or minor earthquakes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wind-resistant and earthquake-resistant steel pipe column structure with reinforcing ribs includes a steel pipe column. The steel pipe column has a reinforcing rib mechanism inside, which includes cross reinforcing ribs. The cross reinforcing ribs are fixedly connected at equal intervals inside the steel pipe column. The outer side of the cross reinforcing ribs is symmetrically fixedly connected to diagonal bracing plates. The diagonal bracing plates are fixedly connected to the inner wall of the steel pipe column. The inside of the cross reinforcing ribs is fixedly connected to a connecting ring. Weight-reducing grooves are formed inside the cross reinforcing ribs and diagonal bracing plates.

[0008] By incorporating a reinforcing rib mechanism, the reinforcing ribs and diagonal bracing plates enhance bending stiffness, while the pressure relief grooves reduce wind pressure impact. This ensures the stability of the structure under wind loads and seismic action, extends its service life, and fully meets the stringent requirements of modern engineering structures for safety and durability.

[0009] In a preferred embodiment, the outer wall of the steel pipe column is uniformly provided with multiple pressure-reducing grooves along its axial and circumferential directions, and the interior of the cross-shaped reinforcing rib is provided with corresponding ventilation grooves. The ventilation grooves and pressure-reducing grooves are aligned with each other to form an airflow channel, so as to reduce the impact of wind load on the steel pipe column.

[0010] The pressure relief grooves on the outer wall of the steel pipe column are aligned with the ventilation grooves of the cross-shaped reinforcing ribs to form an airflow channel, which effectively reduces the impact of wind pressure on the steel pipe column, reduces the wind vibration effect, and improves wind resistance.

[0011] In a preferred embodiment, a base plate is fixedly connected to the bottom of the steel pipe column, and a stabilizing plate is fixedly connected to the bottom of the base plate. Multiple arc-shaped reinforcing frames are evenly distributed along the circumference on the upper surface of the base plate. The two ends of the reinforcing frames are welded and fixed to the base plate and the outer wall of the steel pipe column, respectively, to improve the overturning resistance of the overall structure.

[0012] The base plate and stabilizing plate enhance the bottom stability of the steel pipe column and prevent overturning, while the arc-shaped reinforcing frame further improves the connection strength between the steel pipe column and the base plate, ensuring the seismic performance of the overall structure.

[0013] In a preferred embodiment, a stabilizing sleeve is fitted onto the top of the steel pipe column, and a top plate is welded to the top of the stabilizing sleeve. Multiple mounting holes are evenly opened along the circumference of the top plate, and mounting bolts are threaded into the mounting holes for fixed connection with the superstructure.

[0014] The stabilizing sleeve and top plate enhance the connection strength at the top of the steel pipe column, and the installation bolts facilitate quick fixing to the superstructure, improving construction efficiency while ensuring the reliability of the node connection.

[0015] In a preferred embodiment, both the bottom surface of the stabilizing disk and the top surface of the top plate are bonded with cushioning rubber pads. The cushioning rubber pads are of uniform thickness and extend to cover the corresponding end faces of the stabilizing disk and the top plate to provide shock absorption.

[0016] The buffer rubber pads provide flexible cushioning at the stabilizing plate and top plate, absorbing the impact energy generated by earthquakes or wind loads, reducing structural vibration, and improving seismic performance.

[0017] In a preferred embodiment, the outer wall of the steel pipe column is coated with a composite anti-rust coating, which includes a primer, an intermediate coat, and a topcoat to improve the weather resistance and corrosion resistance of the steel pipe column.

[0018] The composite anti-rust coating effectively isolates the steel pipe column from the external environment, prevents rust, extends service life, and improves weather resistance, making it suitable for harsh environments.

[0019] The wind-resistant and earthquake-resistant steel pipe column structure with reinforcing ribs provided by this utility model has the following advantages:

[0020] Firstly, the reinforced ribs and diagonal bracing enhance the bending stiffness, while the pressure relief grooves reduce wind pressure impact. This ensures the stability of the structure under wind loads and earthquakes, extends its service life, and fully meets the stringent requirements of modern engineering structures for safety and durability.

[0021] Secondly, the base plate and stabilizing plate enhance the stability of the steel pipe column at the bottom, preventing overturning. The arc-shaped reinforcing frame further improves the connection strength between the steel pipe column and the base plate, ensuring the overall seismic performance of the structure. The stabilizing sleeve and top plate enhance the connection strength at the top of the steel pipe column, and the installation bolts facilitate quick fixing to the superstructure, improving construction efficiency while ensuring the reliability of the joint connections. Buffer rubber pads provide flexible cushioning at the stabilizing plate and top plate, absorbing the impact energy generated by earthquakes or wind loads, reducing structural vibration, and improving seismic performance. The composite anti-rust coating effectively isolates the steel pipe column from the external environment, preventing corrosion, extending service life, and improving weather resistance, making it suitable for harsh environments.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] The wind-resistant and earthquake-resistant steel pipe column structure with reinforcing ribs disclosed in this utility model is mainly applied to the application scenarios of steel pipe columns.

[0030] Reference Figures 1-5 A wind-resistant and earthquake-resistant steel pipe column structure with reinforcing ribs includes a steel pipe column 1. The steel pipe column 1 has an internal reinforcing rib mechanism, including cross-shaped reinforcing ribs 2. The cross-shaped reinforcing ribs 2 are equidistantly fixedly connected inside the steel pipe column 1. Diagonal bracing plates 3 are symmetrically fixedly connected to the outer sides of the cross-shaped reinforcing ribs 2, and the diagonal bracing plates 3 are fixedly connected to the inner wall of the steel pipe column 1. Connecting rings 4 are fixedly connected inside the cross-shaped reinforcing ribs 2. Weight-reducing grooves 5 are formed inside the cross-shaped reinforcing ribs 2 and the diagonal bracing plates 3. Multiple pressure-reducing grooves 6 are evenly formed along the axial and circumferential directions on the outer wall of the steel pipe column 1. Corresponding ventilation grooves 7 are formed inside the cross-shaped reinforcing ribs 2. The ventilation grooves 7 and the pressure-reducing grooves 6 are aligned with each other to form airflow channels, thereby reducing the impact of wind loads on the steel pipe column 1.

[0031] In this embodiment, the cross-shaped reinforcing ribs 2 and the diagonal bracing plates 3 achieve excellent wind and earthquake resistance. The cross-shaped reinforcing ribs 2 inside the steel pipe column 1 are evenly distributed along the axial direction, forming a stable skeleton support system, which significantly improves the overall bending stiffness and lateral displacement resistance, enhancing the overall rigidity and bending capacity, enabling it to effectively resist wind loads and seismic forces. The pressure-reducing grooves 6 on the outer wall of the steel pipe column 1 and the ventilation grooves 7 of the cross-shaped reinforcing ribs 2 are interconnected, forming an efficient airflow channel system. When strong winds occur, the airflow can smoothly pass through the pressure-reducing grooves 6 and ventilation grooves 7, significantly reducing the impact of wind pressure on the steel pipe column 1 and mitigating the influence of wind pressure. Through the set reinforcing rib mechanism, the reinforcing ribs and diagonal bracing plates 3 improve the bending stiffness, and the pressure-reducing grooves 6 reduce the impact of wind pressure, ensuring the stability of the structure under wind loads and seismic forces, extending its service life, and fully meeting the stringent requirements of modern engineering structures for safety and durability.

[0032] In the above technical solution, considering that most existing steel pipe columns are hollow and lack internal reinforcing ribs to strengthen their strength, they are prone to breakage in the event of strong winds or minor earthquakes, the following specific operation is implemented to solve this problem:

[0033] Reference Figures 1-5 In a preferred embodiment, a base plate 8 is fixedly connected to the bottom of the steel pipe column 1, and a stabilizing plate 10 is fixedly connected to the bottom of the base plate 8. Multiple arc-shaped reinforcing frames 9 are evenly distributed along the circumference of the upper surface of the base plate 8. The two ends of the reinforcing frames 9 are welded and fixed to the base plate 8 and the outer wall of the steel pipe column 1, respectively, to improve the overall structure's resistance to overturning. A stabilizing sleeve 11 is fitted onto the top of the steel pipe column 1, and a top plate 12 is welded to the top of the stabilizing sleeve 11. Multiple mounting holes are evenly opened along the circumference of the top plate 12, and mounting bolts 13 are threaded into the mounting holes for fixed connection to the upper structure. Buffer rubber pads 14 are adhered to the bottom surface of the stabilizing plate 10 and the top surface of the top plate 12. The buffer rubber pads 14 have a uniform thickness and their edges extend to cover the corresponding end faces of the stabilizing plate 10 and the top plate 12 to provide shock absorption. The outer wall of the steel pipe column 1 is coated with a composite anti-rust coating, which includes a primer, an intermediate coat and a topcoat, to improve the weather resistance and corrosion resistance of the steel pipe column 1.

[0034] In this embodiment: the base plate 8 and the stabilizing plate 10 enhance the bottom stability of the steel pipe column 1, preventing overturning. The arc-shaped reinforcing frame 9 further improves the connection strength between the steel pipe column 1 and the base plate 8, ensuring the seismic performance of the overall structure. The stabilizing sleeve 11 and the top plate 12 enhance the connection strength at the top of the steel pipe column 1. The mounting bolts 13 facilitate quick fixing to the superstructure, improving construction efficiency while ensuring the reliability of the node connections. The buffer rubber pads 14 provide flexible buffering at the stabilizing plate 10 and the top plate 12, absorbing the impact energy generated by earthquakes or wind loads, reducing structural vibration, and improving seismic performance. The composite anti-rust coating effectively isolates the steel pipe column 1 from contact with the external environment, preventing corrosion, extending service life, and improving weather resistance, making it suitable for harsh environments.

[0035] Working Principle: This steel pipe column structure achieves excellent wind and earthquake resistance through internal cross-shaped reinforcing ribs 2 and diagonal bracing plates 3. The cross-shaped reinforcing ribs 2 inside the steel pipe column 1 are evenly distributed along the axial direction, forming a stable skeleton support system, which greatly improves the overall bending stiffness and lateral displacement resistance, enhancing the overall rigidity and bending capacity, enabling it to effectively resist wind loads and seismic forces. The pressure-reducing grooves 6 on the outer wall of the steel pipe column 1 are interconnected with the ventilation grooves 7 of the cross-shaped reinforcing ribs 2, forming an efficient airflow channel system. When strong winds occur, airflow can smoothly pass through the pressure-reducing grooves 6 and ventilation grooves 7, significantly reducing the impact of wind pressure on the steel pipe column 1 and minimizing the influence of wind pressure. The base plate 8 and stabilizing plate 10 provide stable bottom support, the reinforcing frame 9 prevents overturning, the top stabilizing sleeve 11 and top plate 12 ensure reliable connection with the upper structure, the buffer rubber pad 14 absorbs vibration energy and reduces impact, and the composite anti-rust coating protects the steel pipe column 1 from corrosion, ensuring long-term stable use.
