Description

Technical Field

[0001] This application relates to the fields of electrified railways and urban rail transit, and particularly to a common base for support columns and longitudinal cables and an installation method thereof. Background Art

[0002] In electrified railways and urban rail transit systems, columns (such as catenary poles, guy poles, etc.) and longitudinal cables (such as power supply cables, communication cables, etc.) are key infrastructure for supporting the operation of the system. Catenary poles are used to support the catenary and provide electrical energy for electric locomotives or electric trains; guy poles are mainly used to enhance the stability of catenary poles or signal equipment; longitudinal cables are used to transmit power, signals and data to ensure the normal operation of the entire system. However, existing technical solutions usually design the support structures for columns and longitudinal cables separately, resulting in the following problems:

[0003] (1) Low space utilization rate. Separate support structures need to be installed for columns and longitudinal cables respectively, occupying a large amount of ground and space resources. In areas with urban rail transit or complex terrain (such as tunnels, bridges, etc.), space resources are relatively scarce, and the separately designed support structures will increase the lateral width of the main structure, thus increasing project investment.

[0004] (2) High construction cost. Using separate support structures for columns and longitudinal cables requires additional materials and construction work, thus increasing the construction cost.

[0005] (3) Cable troughs are usually made of thin steel plates, with weak stiffness. Under the action of train vibration, wind load and temperature change, the cable troughs are prone to deformation or damage. Summary of the Invention

[0006] This application provides a common base structure for support columns and longitudinal cables and an installation method thereof, aiming to reduce the space occupied by the structure, lower the construction cost, and improve the stability of the structure.

[0007] In a first aspect, an embodiment of the present application provides a common base for a support column and a longitudinal cable, including: two longitudinal webs, which are parallel to each other and arranged along the longitudinal direction of the bridge; a plurality of supporting plates, which are arranged between the two longitudinal webs at equal intervals and parallel to each other, and each supporting plate is perpendicularly installed to the longitudinal web, and an opening for accommodating the longitudinal cable is formed upward on the supporting plate; two top plates, which are respectively located on both sides of the opening and are laid on the top surfaces of the longitudinal web and each supporting plate, and the two top plates are used to support the column. In this embodiment, by arranging the two longitudinal webs parallel to each other along the longitudinal direction of the bridge, it is ensured that the longitudinal cable is installed between the two longitudinal webs, realizing the lateral limit of the longitudinal cable. In order to further fix the longitudinal cable, a plurality of supporting plates are further arranged between the two longitudinal webs, and all the supporting plates are arranged at equal intervals and parallel to each other, so that the load can be evenly distributed on each supporting plate, avoiding excessive pressure on individual parts, ensuring that the bearing capacity of the structure is maximized, and at the same time arranging each supporting plate perpendicular to the longitudinal web, so that a frame structure can be formed, effectively enhancing the bending resistance and stability of the overall structure, and ensuring that the structure can maintain its shape and bearing capacity under various load conditions. By forming an opening for accommodating the longitudinal cable upward on the supporting plate, the supporting plate effectively supports the longitudinal cable, ensuring the stability of the longitudinal cable installation, and at the same time avoiding the longitudinal cable contacting the accumulated water on the bridge surface in rainy weather. By laying two top plates on the top surfaces of the longitudinal web and each supporting plate and installing the two top plates on both sides of the opening, it will not prevent the longitudinal cable from being put into the opening, and can also share part of the load, further improving the bearing capacity and stability of the overall structure, and being used to support the column. In this way, through the common base provided by this embodiment, the support column and the longitudinal cable can be realized at the same time, reducing the space occupied by the structure, reducing the construction cost, and improving the stability of the structure.

[0012] In combination with the first aspect, in some embodiments, a mounting plate is installed below the column, and the mounting plate covers the tops of the two top plates.

[0013] In combination with the first aspect, in some embodiments, it further includes a splicing plate, which is laid on the top surfaces of the two top plates and is located below the mounting plate. The splicing plate, the top plate, and the mounting plate are bolted together by high-strength bolts.

[0014] In combination with the first aspect, in some embodiments, it further includes a plurality of outer stiffening plates, which are symmetrically arranged on the outer sides of the two longitudinal webs respectively. The outer stiffening plates are aligned with the supporting plates across the longitudinal webs, and the top plates are laid on the top surfaces of the longitudinal webs, each supporting plate, and each outer stiffening plate.

[0015] In combination with the first aspect, in some embodiments, there are openings between the four corners of the supporting plate and the longitudinal web, and between the two corners of the outer stiffening plate close to the longitudinal web and the longitudinal web.

[0016] In the second aspect, the embodiments of the present application provide an installation method for a common base of a support column and a longitudinal cable based on any one of the above embodiments, including: along the longitudinal direction of the bridge, installing a plurality of supporting plates at equal intervals and parallel to each other on the bridge deck, with the openings of the supporting plates facing upward; installing the two longitudinal webs on both sides of the supporting plates respectively, the two longitudinal webs being parallel to each other and the longitudinal webs being perpendicular to the supporting plates; laying the two top plates flat on the top surfaces of the longitudinal webs and the supporting plates, the two top plates being located on both sides of the opening respectively; fixing the longitudinal cable in the opening, and then installing the column on the top surfaces of the two top plates.

[0036] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0037] The embodiments of this application provide a common base for supporting columns and longitudinal cables and an installation method, aiming to reduce the space occupied by the structure, lower the construction cost, and improve the stability of the structure.

[0038] In the first aspect, refer to Figures 1 - 3 , Figure 1 which is a front view of the common base for supporting column 9 and longitudinal cable 8 in the embodiments of this application; Figure 2 is Figure 1 a side view of Figure 3 is Figure 1 a top view of Figures 1 - 3As shown in the figure, the common base of the support column 9 and the longitudinal cable 8 includes: two longitudinal webs 1, two top plates 3 and several supporting plates 2. The two longitudinal webs 1 are arranged on the bridge deck 10 along the longitudinal bridge direction in parallel. The bridge deck 10 is generally a steel bridge deck 10, and the longitudinal webs 1 can be fixed to the bridge deck 10 by welding. Several supporting plates 2 are also provided between the two longitudinal webs 1. All the supporting plates 2 are arranged at equal intervals along the longitudinal bridge direction, and at the same time, adjacent two supporting plates 2 are parallel to each other. Each supporting plate 2 is vertically installed with the longitudinal web 1, and can also be installed by welding. It should be noted that the supporting plate 2 here is mainly used to support the longitudinal cable 8 and share the load borne by the base. An opening 21 for accommodating the longitudinal cable 8 is opened upward on the supporting plate 2 to ensure the stable support of the longitudinal cable 8. Two top plates are also laid and installed on the top surfaces of the longitudinal web 1 and each supporting plate 2. These two top plates 3 are respectively located on both sides of the opening 21 of the supporting plate 2. Equivalent to passing through these two top plates 3, the two longitudinal webs 1 and all the supporting plates 2 are connected into a whole, and a stable supporting plane can be formed to support the column 9. And the column 9 here generally refers to a catenary column 9, a guy wire column 9, etc., which mainly plays a role in bearing and supporting.

[0039] In this embodiment, by arranging the two longitudinal webs 1 parallel to each other along the longitudinal bridge direction, it is ensured that the longitudinal cable 8 is installed between the two longitudinal webs 1, realizing the lateral limit of the longitudinal cable 8. In order to further fix the longitudinal cable 8, several supporting plates 2 are also provided between the two longitudinal webs 1. All the supporting plates 2 are arranged at equal intervals and parallel to each other, so that the load can be evenly distributed on each supporting plate 2, avoiding excessive pressure on individual parts, ensuring that the bearing capacity of the structure is maximized, and at the same time, each supporting plate 2 is vertically arranged with the longitudinal web 1, so that a frame structure can be formed, effectively enhancing the bending resistance and stability of the overall structure, and ensuring that the structure can maintain its shape and bearing capacity under various load conditions. By opening an opening 21 for accommodating the longitudinal cable 8 upward on the supporting plate 2, the supporting plate 2 effectively supports the longitudinal cable 8, ensuring the stability of the installation of the longitudinal cable 8, and at the same time avoiding the longitudinal cable 8 contacting the accumulated water on the bridge deck in rainy weather. By laying two top plates 3 on the top surfaces of the longitudinal web 1 and each supporting plate 2 and installing the two top plates 3 on both sides of the opening 21, this will not prevent the longitudinal cable 8 from being put into the opening 21, and can also share part of the load, further improving the bearing capacity and stability of the overall structure to support the column 9. In this way, through the common base provided by this embodiment, the support column 9 and the longitudinal cable 8 can be realized at the same time, reducing the space occupied by the structure, lowering the construction cost, and improving the stability of the structure.

[0040] Furthermore, in one embodiment, as Figure 1As shown, by setting the opening 21 as a U-shaped opening, a relatively large vertical stress-bearing area can be provided, effectively distributing and bearing the load, improving the pressure-bearing and bending resistance capabilities of the support plate 2, and ensuring that its structure is more stable and durable when stressed; at the same time, the U-shaped opening is more in line with the cross-sectional shape of the longitudinal cable 8, restricting the longitudinal cable 8 in the transverse direction of the bridge.

[0041] Furthermore, in one embodiment, as Figure 1 shown, the common base of the support column 9 and the longitudinal cable 8 further includes a lower clamp 4 and an upper clamp 5. The lower clamp 4 is installed at the bottom of the opening 21, and the longitudinal cable 8 is locked in the opening 21 through the lower clamp 4 and the upper clamp 5. In this embodiment, the common base of the support column and the longitudinal cable 8 further includes a lower clamp 4 and an upper clamp 5. By installing the lower clamp 4 at the bottom of the opening 21 and locking the longitudinal cable 8 in the opening 21 through the lower clamp 4 and the upper clamp 5, not only can the position of the longitudinal cable 8 be fixed, but also a uniform clamping force can be formed on the longitudinal cable 8, so that the longitudinal cable 8 can be stably supported in both the vertical and horizontal directions, enhancing the stability of the longitudinal cable 8 on the common base.

[0042] Furthermore, in one embodiment, as Figure 1 shown, the lower clamp 4 and the upper clamp 5 are connected through the ear plates 41 on both sides; spaces for accommodating the ear plates 41 are provided on both inner walls of the opening 21. In this embodiment, the lower clamp 4 and the upper clamp 5 are usually connected through the ear plates 41 on both sides, and their connection method is bolt connection. By providing spaces for accommodating the ear plates 41 on both inner walls of the opening 21, it is beneficial for the ear plates 41 of the lower clamp 4 and the upper clamp 5 to be connected when fixing the longitudinal cable 8.

[0043] Furthermore, in one embodiment, referring to Figure 4 , Figure 4 is Figure 1 a schematic diagram of the connection between the lower clamp 4 and the upper clamp 5 in Figure 4 shown. As

[0044] shown, a rubber pad 42 is provided between the longitudinal cable 8 and the two clamps. In this embodiment, by providing a rubber pad 42 between the longitudinal cable 8 and the two clamps, a protective effect can be provided to avoid abrasion or external damage.

[0044] Furthermore, in one embodiment, as Figure 1 and Figure 2As shown, a mounting plate 91 is installed below the column 9, and the mounting plate 91 covers the tops of the two top plates 3. In this embodiment, by installing the mounting plate 91 below the column 9 and covering the tops of the two top plates 3 with the mounting plate 91, the weight of the column 9 is evenly distributed to the two top plates 3 through the mounting plate. If the column 9 is subjected to an additional bending load due to an external force, the load received can also be distributed to the two top plates 3 through the mounting plate 91, avoiding the problem of local overload and improving the bearing capacity and stability of the overall structure.

[0045] Further, in one embodiment, as Figure 1 and Figure 2 shown, the common base for supporting the column 9 and the longitudinal cable 8 further includes a splicing plate 6, which is laid on the top surfaces of the two top plates 3 and is located below the mounting plate 91. The splicing plate 6, the top plate 3, and the mounting plate 91 are bolted together with high-strength bolts. In this embodiment, the common base for supporting the column 9 and the longitudinal cable 8 further includes a splicing plate 6. By laying the splicing plate 6 on the top surfaces of the two top plates 3, being located below the mounting plate 91, and bolt-bonding the splicing plate 6, the top plate 3, and the mounting plate 91 together with high-strength bolts, in this way, the splicing plate 6 functions to connect the two top plates 3 and the mounting plate 91, forming a more robust overall structure and enhancing its resistance to external forces such as vibration and impact.

[0046] Further, in one embodiment, as Figure 1 and Figure 2 shown, the common base for supporting the column 9 and the longitudinal cable 8 further includes a number of outer stiffening plates 7, which are symmetrically arranged on the outer sides of the two longitudinal webs 1 respectively. The outer stiffening plates 7 are aligned with the support plates 2 across the longitudinal webs 1, and the top plates 3 are laid on the top surfaces of the longitudinal webs 1, the support plates 2, and the outer stiffening plates 7. In this embodiment, the common base for supporting the column 9 and the longitudinal cable 8 further includes a number of outer stiffening plates 7. By symmetrically arranging all the outer stiffening plates 7 on the outer sides of the two longitudinal webs 1 respectively, each side of the outer stiffening plates 7 is aligned with the support plates 2 across the longitudinal webs 1, enabling the entire structure to remain balanced under the action of external forces, avoiding uneven stress distribution caused by asymmetry of the outer stiffening plates 7, improving the anti-rotation and anti-side deformation capabilities of the structure, and at the same time facilitating the transfer of stress on the support plates 2 to the outer stiffening plates 7 through the longitudinal webs 1. In addition, by laying the top plates 3 on the top surfaces of the longitudinal webs 1, the support plates 2, and the outer stiffening plates 7, it should be noted that there are two top plates 3, which are located on both sides of the opening 21 respectively. Each side of the top plate 3 is laid on the top surfaces of the longitudinal web 1, the support plate 2, and the outer stiffening plate 7 on that side, significantly improving the bending and compressive resistance of the common base, ensuring stability in various external environments, and reducing the risk of deformation and damage.

[0047] Further, in one embodiment, as Figure 1As shown, openings 22 are provided between the four corners of the support plate 2 and the longitudinal web 1, and between the two corners of the outer stiffening plate 7 close to the longitudinal web 1 and the longitudinal web 1. In this embodiment, openings 22 are provided between the four corners of the support plate 2 and the longitudinal web 1, and between the two corners of the outer stiffening plate 7 close to the longitudinal web 1 and the longitudinal web 1. These openings 22 are for convenient welding to avoid cross - welding and can also be called weld - through holes. However, it should still be noted that the openings 22 between the two bottom corners of the support plate 2 and the longitudinal web 1, and the openings 22 between the bottom corners of the outer stiffening plate 7 close to the longitudinal web 1 and the longitudinal web 1 also have the function of draining water, which can prevent rainwater from accumulating here and causing rust.

[0048] In a second aspect, referring to Figure 5 , Figure 5 is a flowchart of the installation method of the common base for the support column 9 and the longitudinal cable 8 in the embodiment of the present application. As Figure 5 shown, in one embodiment, the steps of the installation method of the common base for the support column 9 and the longitudinal cable 8 include:

[0049] Step S10, along the longitudinal bridge direction, install a plurality of support plates 2 on the bridge deck 10 at equal intervals and parallel to each other, with the openings 21 of the support plates 2 facing upward.

[0050] In this embodiment, when installing a plurality of support plates 2, it is necessary to ensure that the openings 21 of the support plates 2 face upward for the convenience of installing the longitudinal cable 8 in the openings 21. During the actual installation process, it is necessary to first measure and mark along the longitudinal bridge direction, install a plurality of support plates 2 according to the principle of equal - interval and parallel arrangement, and ensure that the positions of the support plates 2 are accurately placed according to the design requirements. Then, use appropriate connection methods such as welding and bolt connection to fix the support plates 2 on the bridge deck 10. And after the installation is completed, quality inspection is also required to ensure that all support plates 2 are installed correctly and meet the design and safety standards.

[0051] Step S20, install two longitudinal webs 1 on both sides of the support plate 2 respectively. The two longitudinal webs 1 are parallel to each other, and the longitudinal web 1 is perpendicular to the support plate 2.

[0052] In this implementation, when installing two longitudinal webs 1 on both sides of the support plate 2 respectively, it should be noted that one longitudinal web 1 is installed on one side of all support plates 2. When installing the two longitudinal webs 1, it is necessary to ensure that the two longitudinal webs 1 are parallel to each other and the longitudinal web 1 is perpendicular to the support plate 2. In this way, the loads in different directions can be separated. The longitudinal web 1 bears the longitudinal load, and the support plate 2 bears the transverse load. At the same time, the parallel installation of the two longitudinal webs 1 can provide symmetric support, avoid structural imbalance, and improve stability. The installation method between the longitudinal web 1 and the support plate 2 can be welding.

[0053] Step S30: Lay and install two top plates 3 on the top surfaces of the longitudinal webs 1 and the support plates 2. The two top plates 3 are respectively located on both sides of the opening 21.

[0054] In this embodiment, laying and installing two top plates 3 on the top surfaces of the longitudinal webs 1 and the support plates 2 makes the top plates 3, the longitudinal webs 1 and the support plates 2 form an integral structure, which is beneficial to the stability of the structure. At the same time, the two top plates 3 are respectively located on both sides of the opening 21, so that the opening 21 will not be blocked, which is beneficial to the taking and placing of the longitudinal cable 8 and facilitates the installation, maintenance or replacement of the longitudinal cable 8.

[0055] Step S40: Fix the longitudinal cable 8 in the opening 21, and then install the column 9 on the top surfaces of the two top plates 3.

[0056] In this embodiment, the longitudinal cable 8 is fixed in the opening 21 through a fixing component (such as a clamp), and then the column 9 is installed on the top surfaces of the two top plates 3 through a fixing component (such as a bolt). In this way, the longitudinal cable 8 and the column 9 can be fixed on the same base, realizing the support of the column 9 and the longitudinal cable 8, reducing the space occupied by the structure, lowering the construction cost, and improving the stability of the structure.
