Description

Technical Field

[0001] This invention relates to the field of bridge engineering technology, specifically to a connection device for bridge ancillary facilities. Background Technology

[0002] With the continuous acceleration of urbanization in my country, the landscape design of urban bridges is receiving increasing attention. During the use of arch bridges, it is often necessary to add landscape decoration structures, power facilities, sightseeing walkways and other ancillary works to the main structure. In addition, the ancillary facilities will inevitably involve material aging and equipment replacement issues during daily use. Therefore, it is necessary to add maintenance access and fire access for routine maintenance.

[0003] In the existing technology, the conventional practice for installing auxiliary works on the arch ribs of arch bridges is to directly weld ear plates to the main structure for connection. This method has the defect of stress redistribution in the arch ribs caused by welding. Especially for large urban bridges, the stress level of the arch ribs is high, and a large amount of welding can cause local damage to the main structure of the bridge, and even reduce the safety level of the bridge structure. Summary of the Invention

[0004] In view of the above problems, the present invention provides a connecting device for bridge ancillary facilities that overcomes or at least partially solves the above problems, and can solve the problem in the prior art that welding ear plates to arch ribs endangers bridge safety, thereby achieving the effect of installing ancillary facilities without affecting bridge safety.

[0005] Specifically, the present invention provides a connection device for bridge ancillary facilities, comprising:

[0006] A clamp, which is fitted onto the arch box of the bridge;

[0007] The longitudinal beam is connected to the clamp;

[0008] Ear plates are mounted on the longitudinal beams and are used to install auxiliary facilities.

[0009] Optionally, the longitudinal beam has the same line shape as the arch rib of the bridge;

[0010] The plane in which the clamp is located is perpendicular to the axis of the arch rib.

[0011] Optionally, the number of clamps is multiple, and the distance between two adjacent clamps is no more than 3.5m.

[0012] Optionally, the clamp includes:

[0013] The crossbeams are two in number and are arranged in parallel.

[0014] The vertical rods are two in number; the vertical rods and the horizontal beams are connected end to end to form a ring, so as to encircle the arch box;

[0015] The longitudinal beam is connected to the transverse beam or the vertical rod.

[0016] Optionally, at least one of the crossbeams forms a support portion extending out of the annular shape; the longitudinal beam overlaps the support portion.

[0017] Optionally, the crossbeam and the vertical rod are detachably connected.

[0018] Optionally, a reinforcing plate is connected between the crossbeam and the longitudinal beam, and the reinforcing plate is disposed on the side of the longitudinal beam away from the vertical rod, so that the longitudinal beam is located between the vertical rod and the reinforcing plate.

[0019] Optionally, a connecting plate is provided between the support portions of two adjacent crossbeams.

[0020] Optionally, a railing post is provided at the end of the support that is away from the vertical bar, and the railing post is arranged perpendicular to the support; a railing bar is connected between two adjacent railing posts.

[0021] Optionally, the connecting plate is provided with multiple pedals, and the distance between two adjacent pedals is no more than 100mm.

[0022] The beneficial effects of this invention are as follows:

[0023] The connecting device for bridge ancillary facilities provided by this invention employs a method of fitting a clamp onto the arch box, setting a longitudinal beam on the clamp, and setting an ear plate on the longitudinal beam to facilitate the installation of ancillary facilities on the ear plate. Since the ancillary facilities are not welded to the main bridge structure, the impact on the stress of the main bridge structure is minimal. This solves the problem in existing technologies where welding ear plates to the arch ribs endangers bridge safety, achieving the effect of installing ancillary facilities without affecting bridge safety, and thus facilitating widespread application.

[0024] Furthermore, in the connecting device for bridge ancillary facilities provided by the present invention, since the plane of the clamp is perpendicular to the axis of the arch rib, and the longitudinal beam has the same line shape as the arch rib of the bridge, when the longitudinal beam undergoes a slight displacement under the action of external force, it will cause a difference in line shape between the longitudinal beam and the main arch of the bridge, thereby causing the clamp to automatically lock to prevent the longitudinal beam from sliding down. This effectively solves the anti-slip problem between the clamp and the main bridge structural components, thus improving the stability and anti-slip performance of the connecting device.

[0025] Furthermore, in the connecting device for bridge ancillary facilities provided by the present invention, the crossbeam and the vertical rod are detachably connected, which facilitates installation and maintenance.

[0026] Furthermore, in the connecting device for bridge ancillary facilities provided by this invention, the position of the clamp can be adjusted according to the arrangement of the main bridge arch rib nodes and splice plates during installation, thus exhibiting strong adaptability to bridge structures. The longitudinal beams are arranged along the main arch of the bridge, and the ear plates are installed at any position on the longitudinal beams, demonstrating strong adaptability to the installation of ancillary facilities. The specific dimensions of the crossbeams and vertical members can be adjusted according to the structural stress to accommodate bridges of different sizes; the specific dimensions of the longitudinal beams can be adjusted according to the stress on the ancillary facilities to accommodate ancillary facilities of different weights.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] Figure 1 This is a schematic structural diagram of a connection device for bridge ancillary facilities according to an embodiment of the present invention, such as... Figure 1 As shown, and refer to Figures 2 to 4 This invention provides a connecting device for bridge ancillary facilities, including a clamp 100, a longitudinal beam 200, and an ear plate 300. The clamp 100 is fitted onto the arch box 400 of the bridge; the longitudinal beam 200 is connected to the clamp 100; and the ear plate 300 is disposed on the longitudinal beam 200 and is used to install the ancillary facilities. Specifically, the longitudinal beam 200 and the clamp 100 are connected by welding to prevent the longitudinal beam 200 from detaching from the clamp 100; similarly, the longitudinal beam 200 and the ear plate 300 are connected by welding to prevent the longitudinal beam 200 from detaching from the ear plate 300.

[0039] In this embodiment of the invention, a method is adopted where a clamp 100 is fitted onto the arch box 400, a longitudinal beam 200 is set on the clamp 100, and an ear plate 300 is set on the longitudinal beam 200, so that auxiliary facilities can be installed on the ear plate 300. Since the auxiliary facilities are not welded to the main bridge structure, the impact on the stress of the main bridge structure is minimal. This solves the problem in the prior art where welding the ear plate 300 to the arch rib 500 endangers bridge safety, achieving the effect of installing auxiliary facilities without affecting bridge safety, thus facilitating widespread application. Specifically, it can be promoted and used in highway or municipal bridge construction, landscape lighting projects, and old bridge renovation to realize its social benefits.

[0040] In some embodiments of the present invention, the plane of the clamp 100 is perpendicular to the axis of the arch rib 500; the longitudinal beam 200 is aligned with the arch rib 500 of the bridge. This arrangement ensures that when the longitudinal beam 200 undergoes slight displacement under external force, a difference in alignment between the longitudinal beam 200 and the main arch of the bridge will occur, causing the clamp 100 to automatically lock, thus preventing the longitudinal beam 200 from slipping. This effectively solves the anti-slip problem between the clamp 100 and the main bridge structural components, thereby improving the stability and anti-slip properties of the connection device. In application, the longitudinal beam 200 is arranged along with the main arch of the bridge, and the ear plate 300 is installed at any position on the longitudinal beam 200, providing strong adaptability for the installation of auxiliary facilities.

[0041] In some embodiments of the present invention, multiple clamps 100 are provided, spaced apart, to provide stable support for the longitudinal beam 200. When installing the clamps 100, their positions can be adjusted according to the arrangement of the main bridge arch rib 500 nodes and splice plates, thus exhibiting strong adaptability to bridge structures. Transverse diaphragms are arranged on the longitudinal beam 200 at the clamp 100 support positions. Furthermore, to avoid excessive distance between adjacent clamps 100, which would prevent stable support for the longitudinal beam 200, the distance between adjacent clamps 100 is no greater than 3.5m.

[0042] In some embodiments of the present invention, such as Figures 2 to 4As shown, the clamp 100 includes a crossbeam 110 and a vertical bar 120. There are two crossbeams 110, which are arranged in parallel. There are two vertical bars 120. The vertical bars 120 and the crossbeams 110 are connected end to end to form a ring, so as to hug the arch box 400. The longitudinal beam 200 is connected to the crossbeams 110 or the vertical bars 120.

[0043] In this embodiment of the invention, the specific dimensions of the crossbeam 110 and the vertical rod 120 can be adjusted according to the structural stress. Preferably, the crossbeam 110 can be made of welded channel steel with a height of 440mm and a flange width of 200mm, wherein the web thickness is 32mm and the flange thickness is 20mm. The vertical rod 120 can be made of welded channel steel with a height of 340mm and a flange width of 200mm, wherein the web thickness is 28mm and the flange thickness is 20mm. Meanwhile, the specific dimensions of the longitudinal beam 200 can be adjusted according to the stress of the auxiliary facilities. Preferably, the longitudinal beam 200 is 500mm high and 300mm wide; the top and bottom plates can transition from 16mm at the arch foot to 24mm at the arch top according to the stress. Ear plates 300 are welded to the bottom plate of the longitudinal beam 200 to allow the auxiliary facilities to be installed on the ear plates 300.

[0044] In some embodiments of the invention, at least one crossbeam 110 has an extending annular support portion 111; the longitudinal beam 200 overlaps the support portion 111. This arrangement allows the support portion 111 to support the longitudinal beam 200, thereby improving the stability of the longitudinal beam 200. Figure 3 , Figure 4 As shown, a reinforcing plate 600 is connected between the crossbeam 110 and the longitudinal beam 200. The reinforcing plate 600 is located on the side of the longitudinal beam 200 away from the vertical bar 120, so that the longitudinal beam 200 is located between the vertical bar 120 and the reinforcing plate 600.

[0045] Preferably, the lower crossbeam 110 is overhanging to form a support portion 111. This crossbeam 110 is locally reinforced at the support longitudinal beam 200 using a reinforcing plate 600. The reinforcing plate 600 is welded to both the crossbeam 110 and the longitudinal beam 200 to strengthen the longitudinal connection and simultaneously form an integral structure with the reinforcing plate 600, crossbeam 110, and longitudinal beam 200. This further prevents the crossbeam 110 and longitudinal beam 200 from separating or detaching. When the longitudinal beam 200 undergoes slight displacement under external force, it causes a difference in alignment between the longitudinal beam 200 and the main arch of the bridge, which in turn causes the clamp 100 to automatically lock, preventing the longitudinal beam 200 from slipping. This effectively solves the anti-slip problem between the clamp 100 and the main bridge structural components, thus improving the stability and anti-slip properties of the connection device. The lower crossbeam 110 can be locally reinforced with ribs at the position where it connects to the main structural arch box 400.

[0046] In some embodiments of the present invention, the crossbeam 110 and the vertical rod 120 are detachably connected to facilitate installation and maintenance. Preferably, the crossbeam 110 and the vertical rod 120 can be connected by 3 rows and 3 columns of M30 high-strength bolts, with a clear spacing of not less than 100mm between the high-strength bolts.

[0047] In some embodiments of the present invention, such as Figure 2 As shown, a connecting plate 710 is provided between the support portions 111 of two adjacent crossbeams 110. This arrangement allows the connecting plate 710 to form a maintenance passage and / or fire escape route. When the materials of the auxiliary facilities age and need to be replaced, workers can walk on the connecting plate 710 to reach any position of the connecting device and inspect or replace the auxiliary facilities there, thus meeting the needs of daily maintenance.

[0048] In some embodiments of the present invention, in order to facilitate the walking of workers, the connecting plate 710 is provided with a plurality of pedals 720, and the distance between two adjacent pedals 720 is no more than 100mm.

[0049] Preferably, the connecting plate 710 can be made of one or two angle steels, and the crossbeam 110 is welded to the angle steels; when two angle steels are used, the spacing between the angle steels can be set to 60mm or can be set as needed. The pedal 720 can be made of round steel with a diameter of 16mm, and the round steel is welded between the two angle steels. The distance between the two round steels can be 80mm, 100mm, etc.

[0050] In some embodiments of the present invention, a railing post 730 is provided at the end of the support portion 111 away from the vertical bar 120, and the railing post 730 is arranged perpendicularly to the support portion 111; a railing bar connects two adjacent railing posts 730. This arrangement allows the arch rib 500, the connecting plate 710, and the railing bar to form an upward-opening, three-sided enclosed passage, protecting workers from falling when walking on the connecting plate 710.

[0051] In application, after the crossbeam 110 and vertical rod 120 are installed at appropriate positions on the arch box 400, they are connected together using M30 high-strength bolts to form a clamp 100 encircling the arch box 400. Multiple clamps 100 are then installed sequentially. A longitudinal beam 200, with a line conforming to the arch rib 500 of the bridge, is placed on the support portion 111 of the crossbeam 110, positioned lower relative to it, and then welded to the crossbeam 110. The ear plate 300 can be pre-welded to the longitudinal beam 200, or it can be welded to the longitudinal beam 200 after the crossbeam 110 has been welded together. The ear plate 300 is used to install auxiliary facilities. Because auxiliary facilities are not welded to the main bridge structure, the impact on the stress of the main bridge structure is minimal. This solves the problem in the prior art where welding ear plates 300 to the arch rib 500 endangers bridge safety, achieving the effect of installing auxiliary facilities without affecting bridge safety, thus facilitating widespread application.
