Description

Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to a connecting base for adding facilities in the intelligent transformation of bridges and a bridge. Background Technique

[0002] The intelligent transformation of bridges is a new type of bridge transformation method that has emerged in recent years with the progress of technology. It integrates advanced information technologies such as the Internet of Things, big data, and cloud computing, and combines GIS and BIM models to achieve intelligent management and maintenance of bridges. The key to the intelligent transformation of bridges lies in using advanced sensing technologies and information systems to improve the efficiency and safety of bridge management, and it is necessary to install sensors, monitoring devices, intelligent gantries, intelligent lamp posts, etc. on existing bridges.

[0003] In the early bridge structure design, due to the limitations of specifications and standards, the cantilever structure design generally did not reserve installation space for the recently emerging intelligent transformation facilities, nor did it consider the additional loads caused by relevant facilities. After adding intelligent transformation facilities, it is easy to find that the bearing capacity and crack resistance of the bridge cantilever structure cannot meet the requirements, resulting in a significant reduction in the safety and durability of the bridge structure.

[0004] Existing bridge installation facilities are generally connected to the guardrail by bolts or steel bars, but the bridge structure is not strengthened. The additional loads brought by the installation facilities greatly increase the bending moment borne by the cantilever structure, resulting in insufficient bearing capacity and cracking risks of the bridge cantilever, threatening the safety and service performance of the bridge structure.

[0005] Another type of technology considers the needs of future possible installation facilities during the design stage of the bridge main structure, reserves the space and platform required for facility installation, and makes special designs for the cantilever structure. However, this type of design increases the complexity and cost of bridge structure design and construction, is not conducive to standardized design; the position of the reserved platform is difficult to adjust according to the needs of later installation facilities; the structural stress and size of the reserved platform limit the scale and form of later installation facilities.

[0056] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0057] Embodiment 1

[0058] The bridge intelligent transformation and installation facility connection base provided in the embodiment of the utility model is applied to the bridge, including a facility platform 1, a first connecting member 2, a strut 4 and a second connecting member 6; the top surface of the facility platform 1 is set as a plane, the bottom surface is hinged to the strut 4, and the side wall is fixedly connected to the first connecting member 2, and the first connecting member 2 is used to connect to the cantilever of the bridge; the end of the strut 4 away from the facility platform 1 is hinged to the second connecting member 6, and the second connecting member 6 is used to connect to the main beam 7 of the bridge; the angle between the facility platform 1 and the strut 4 is an acute angle.

[0059] Specifically, the support rod 4 can be provided in plurality as a supporting structure, such as Figure 4As shown, for each additional support rod 4, an additional corresponding second connecting member 6 is added. The hinged support rod 4 can drive the second connecting member 6 to move by rotating, thereby changing the fixed position of the second connecting member 6 and the main beam 7.

[0060] After the facility platform 1 is supported by the hinged strut 4, the strut 4 forms a triangular truss structure with the bridge cantilever and the main beam 7, and the bearing capacity and rigidity are greatly improved. The gravity of the facility platform 1 as a whole is transmitted to the main beam 7 of the bridge by the strut 4, reducing the force on the cantilever and extending the service life of the cantilever. At the same time, by replacing the facility platform 1 of different sizes and shapes and increasing the number of struts 4, the problem of installing new equipment in the later stage can be effectively solved. By changing the angle between the strut 4 and the facility platform 1, it can adapt to different bridge cantilever lengths; by rotating the direction of the second connecting member 6, it can adapt to different bridge inclination angles. This embodiment uses the strut 4 to transmit the load of the installed facilities, which solves the problem that the existing technology load is borne by the cantilever, resulting in insufficient structural bearing capacity and easy cracking. The change in the force transmission path reduces the connection requirements of the bridge intelligent transformation and installation facilities connection base with the bridge cantilever and anti-collision guardrail 8, which is conducive to reducing openings and facilitating construction. The strut 4 forms a triangular truss structure with the bridge cantilever and the main beam 7, which improves the local bearing capacity and rigidity of the bridge structure. The size of the facility platform 1 can be adjusted according to the needs of the additional facilities, and it is applicable to all kinds of facilities. By rotating the first hinge 3, it can adapt to different bridge arm lengths, and by rotating the second hinge 5, it can adapt to different bridge web inclination angles. The components of the connection base of the bridge intelligent transformation and installation facilities can be disassembled and prefabricated in the factory and installed separately on site, reducing the lifting weight and installation difficulty. All components of the connection base of the bridge intelligent transformation and installation facilities are accessible for inspection and repair, which is convenient for later inspection and maintenance.

[0061] In an optional scheme of an embodiment of the utility model, the facility platform 1 includes a support plate 11 and a reinforcing connector 12, the top surface of the support plate 11 is set to be a plane, and the bottom surface is connected to the reinforcing connector 12; the side of the reinforcing connector 12 facing away from the facility platform 1 is hinged to the support rod 4 through the first hinge 3.

[0062] Specifically, in this embodiment, the support plate 11 is configured as a rectangle. Figure 5 As shown, the upper surface of the support plate 11 is set to be a plane. Of course, the solution of setting the support plate 11 to other shapes should also be within the protection scope of this embodiment. The reinforcing connector 12 is connected to the support plate 11 by welding, and the other side of the reinforcing connector 12 is also connected to the first hinge 3 by welding. The reinforcing connectors 12 are arranged in pairs, and the two reinforcing connectors 12 are parallel, such as Figure 3 As shown, each reinforcing connecting member 12 corresponds to a strut 4 .

[0063] By welding a plurality of strengthening connecting members 12 on the support plate 11, the gravity borne by the support plate 11 itself and the pressure transmitted by the facilities installed thereon can be dispersed to the plurality of strengthening connecting members 12, preventing the force received from being too large and causing damage to the facility platform 1.

[0064] In an alternative embodiment of the present utility model, the strengthening connecting member 12 includes a reinforcing rib and a connecting plate. One side of the reinforcing rib is connected to the bottom surface of the facility platform 1, and the other side is perpendicularly connected to the connecting plate. The first hinge 3 is installed on the side of the connecting plate facing away from the reinforcing rib.

[0065] Specifically, the strengthening connecting member 12 is arranged in an inverted T-shaped structure. The bottom of the T-shaped structure is the reinforcing rib, and the top is the connecting plate. The bottom reinforcing rib of the inverted T-shaped structure is directly welded to the bottom surface of the support plate 11, and the top connecting plate is welded to the first hinge 3.

[0066] By using the strengthening connecting member 12 in an inverted T-shaped structure, the strength and rigidity of the facility platform 1 can be enhanced without increasing the wall thickness of the product, so as to save the material consumption, reduce the weight and lower the cost.

[0067] In an alternative embodiment of the present utility model, one end of the strut 4 facing away from the facility platform 1 is hinged to the second connecting member 6 through the second hinge 5.

[0068] Specifically, the strut 4 is hinged to the second connecting member 6 through the second hinge 5. The number of the second connecting members 6 provided corresponds one by one to the number of the struts 4, and the shapes and connection methods of the first hinge 3 and the second hinge 5 connected to both ends of the strut 4 are the same.

[0069] The first hinge 3 can drive the strut 4 to rotate by rotation. The rotation of the strut 4 can drive the second connecting member 6 to move, and the second connecting member 6 can rotate freely, so as to adapt to different inclination angles of the main beam 7 and not be limited by bridges of different specifications and styles. The main function of the strut 4 is to transmit the facility load. At the same time, together with the bridge cantilever and the main beam 7, a triangular truss structure is formed, converting the bending moment originally borne by the bridge cantilever into the axial pressure of the strut 4, greatly improving the stress condition of the cantilever.

[0070] In an alternative embodiment of the present utility model, both the first hinge 3 and the second hinge 5 include a pin shaft 33 and two hinge plate assemblies. The two hinge plate assemblies are arranged at intervals and are both provided with through holes. Both ends of the strut 4 are provided with mounting holes. One end of the strut 4 is located between the two hinge plate assemblies of the first hinge 3. The pin shaft 33 of the first hinge 3 passes through the mounting hole of the strut 4 and the through holes of the two hinge plate assemblies. The other end is located between the two hinge plate assemblies of the second hinge 5. The pin shaft 33 of the second hinge 5 passes through the mounting hole of the strut 4 and the through holes of the two hinge plate assemblies.

[0071] Specifically, the sizes and shapes of the through holes provided in the hinge plate assembly are the same as those of the mounting holes provided at both ends of the support rod 4. The pin shaft 33 is integrally cylindrical. As Figure 6 shown, it has a structure with raised ends, the diameter in the middle is slightly smaller than the inner diameter of the through hole, and the diameters of the raised ends are slightly larger than the inner diameter of the through hole. During installation, the support rod 4 is installed between two hinge plate assemblies. The pin shaft 33 sequentially passes through the first hinge plate assembly, the support rod 4, and the second hinge plate assembly, and finally the pin shaft 33 is upset and anchored. After upset anchoring, the pin shaft 33 will not come out from between the hinge plate and the support rod 4.

[0072] Two hinge plate assemblies sandwich the support plate in the middle. The hinge plate assembly of the first hinge 3 is welded to the connecting plate of the reinforcing connecting member 12 below the support plate 11. When the support rod 4 rotates between the two hinge plate assemblies, the two fixed hinge plate assemblies play a limiting role on the support rod 4 to prevent the support rod 4 from shifting during rotation. The main function of the first hinge 3 is to realize the hinge between the facility platform 1 and the support rod 4. The hinge plate assembly of the second hinge 5 is welded to the second connecting member 6. When the support rod 4 rotates between the two hinge plate assemblies, the second connecting member 6 can change the angle. The main function of this second hinge 5 is to realize the hinge between the support rod 4 and the main beam 7 and ensure that they can rotate relative to each other freely.

[0073] In an alternative solution of the embodiment of the present utility model, the hinge plate assembly includes a fitting hinge main board 31 and a hinge reinforcing board 32; both the hinge main board 31 and the hinge reinforcing board 32 are provided with through holes.

[0074] Specifically, each hinge plate assembly is composed of a hinge main board 31 and a hinge reinforcing board 32. As Figure 6 shown, the hinge main board 31 is an open-hole steel plate with a size larger than that of the hinge reinforcing board 32 and is welded to the reinforcing connecting member 12. The hinge reinforcing board 32 is a circular open-hole steel plate, and one side of it is welded to one side of the hinge main board 31. The hinge reinforcing board 32 has an opening with the same size as that of the hinge main board 31, and the two holes coincide during welding.

[0075] The strength of the hinge main board 31 will decrease after opening the hole, and it is likely to be weakened and damaged due to factors such as vibration and stress during the process of being used as the hinge main body. After adding the hinge reinforcing board 32 with a concentric circle configuration, the overall hinge plate assembly is strengthened and more durable.

[0076] In an alternative solution of the embodiment of the present utility model, a reinforcing member 13 is provided on the bottom surface of the support plate 11; the reinforcing member 13 is arranged at an interval from the reinforcing connecting member 12.

[0077] Specifically, a plate-shaped reinforcing member 13 is provided below the support plate 11. In this embodiment, the support plate 11 is welded to the reinforcing member 13. Of course, the integrally formed manner of the reinforcing member 13 and the support plate 11 can also achieve the same effect and should also be within the protection scope of the embodiments of the present utility model. The arrangement direction of the reinforcing member 13 is the same as that of the reinforcing connecting member 12. The specific number of the selected reinforcing members 13 is calculated according to the overall force of the facility platform 1, and one or more can be provided.

[0078] By using the plate-shaped reinforcing member 13, the stability of the entire facility platform 1 is further improved. And the reinforcing member 13 is not connected to other structures except the facility platform 1, simply playing the role of reinforcing the facility platform 1. The number can be changed arbitrarily according to the situation, which can save more materials, reduce the weight and lower the cost.

[0079] In an alternative solution of the embodiments of the present utility model, the strut 4 includes a strut main board 41 and strut wing plates 42; both ends of the strut main board 41 are respectively hinged to the facility platform 1 and the second connecting member 6; the strut wing plates 42 are fixedly connected to the side wall of the strut main board 41.

[0080] Specifically, the strut main board 41 is the main part of the strut 4, and the positions of the installation holes in the foregoing part are opened at both ends of the strut main board 41. As Figure 7 shown, the strut wing plates 42 are two flat steel plates. In this embodiment, they are fixed to both sides of the narrow side of the strut main board 41 by welding. When fixing, the center line of the strut wing plate 42 coincides with the narrow side of the strut main board 41 and then is welded. The two strut wing plates 42 are symmetric on both sides of the strut main board 41, showing a wing shape. Of course, the strut 4 cast by the integrally formed manner should also be within the protection scope of the present utility model.

[0081] During the use of the strut 4, it is necessary to transfer the force received by the facility platform 1 to the bridge main girder 7, and the strut 4 is at a relatively long lever arm and requires a relatively high bending strength. The main function of setting the strut wing plates 42 is to improve the in-plane and out-of-plane bending stiffness of the member and prevent the strut 4 from buckling and losing stability during use.

[0082] The working mechanism of the bridge intelligent transformation and installation facility connection base provided by the embodiments of the present utility model is as follows: the strut 4 and the bridge cantilever and the main girder 7 form a triangular truss structure, and the vertical load on the facility platform 1 is directly transmitted to the bridge main girder 7 through the strut 4. The first hinge 3 can rotate freely in the plane, and by changing the angle between the strut 4 and the facility platform 1, it can adapt to the change of the bridge cantilever length. When the cantilever is long, the angle between the strut 4 and the facility platform 1 decreases, and the strut 4 supports at a position above the main girder 7; when the cantilever is short, the angle between the strut 4 and the facility platform 1 increases, and the strut 4 supports at a position below the main girder 7. See respectively Figure 8The second hinge 5 can rotate freely in the plane to adapt to different web inclination angles of the main beam 7. Whether it is a vertical web main beam 7 or an inclined web main beam 7, the second connecting member 6 can be fitted with the main beam 7 by rotating the second hinge 5.

[0083] Embodiment 2

[0084] The bridge provided in the embodiment of the utility model includes the intelligent bridge transformation and installation facility connection base provided in the first embodiment, and therefore includes all the beneficial effects in the first embodiment, which will not be repeated here.

[0085] The bridge provided by the embodiment of the utility model also includes a main beam 7, a cantilever arm, and an intelligent transformation device 9; the cantilever arm is installed on the side wall of the main beam 7, the first connecting member 2 in the bridge intelligent transformation and installation facility connection base is connected to the side of the cantilever arm away from the main beam 7, the second connecting member 6 is connected to the main beam 7, the support rod 4, the cantilever arm and the main beam 7 enclose a triangular area; the intelligent transformation device 9 is installed above the facility platform 1.

[0086] Specifically, the first connecting member 2 and the second connecting member 6 are both a vertically arranged rectangular steel plate. One side of the first connecting member 2 is welded to the facility platform 1, and the other side is fitted to the cantilever of the bridge structure and connected with anchor bolts. Figure 2 As shown, the facility platform 1 is reliably connected to the cantilever arm by applying a preload; one side of the second connector 6 is welded to the second hinge 5, and the other side is attached to the main beam 7 of the bridge structure and connected by bolts, and the second hinge 5 is reliably connected to the main beam 7 by applying a preload. The first connector 2 and the second connector 6 are both provided with two rows of holes for the anchor bolts to pass through and anchor. If the bridge is a steel structure, this component can be eliminated and replaced with a welded connection. The position of the second connector 6 can be selected according to the structure of the bridge by rotating the strut 4 to move the second connector 6. The intelligent transformation equipment 9 is installed above the facility platform 1, and the installation method is selected by welding or bolting.

[0087] The bridge intelligent transformation and installation facility connection base is connected to the bridge by setting the first connecting member 2 and the second connecting member 6. The type of bridge structure is not limited. The material can be a concrete structure, a steel structure, a composite structure; the type can be a box beam, a T-beam, a plate beam, etc. The size of the first connecting member 2 can be easily adjusted according to the overall weight and size of the bridge intelligent transformation and installation facility connection base, and the scope of application is wider. The components of the bridge intelligent transformation and installation facility connection base used are disassembled and prefabricated in the factory and installed separately on site, which reduces the hoisting weight and installation difficulty.

[0088] In an optional solution of the embodiment of the utility model, the bridge further comprises an anti-collision guardrail 8, and the anti-collision guardrail 8 is installed above the cantilever arm.

[0089] Specifically, the anti-collision guardrail 8 is installed at the outermost edge above the cantilever, and the outer side of the anti-collision guardrail 8 is flush with the outermost side of the cantilever. As Figure 1 shown, it can be regarded as a part of the whole cantilever. When the first connecting piece 2 is anchored, one row of bolts can be fixed at the outer edge of the base of the anti-collision guardrail 8. The anti-collision guardrail 8 is a traffic safety facility arranged above the cantilever of the bridge structure, and can be concrete structures, steel structures, and composite structure guardrails of different grades.

[0090] The facility platform 1 is arranged on the outer sides of the bridge cantilever and the guardrail. When anchoring, the outer plane of the existing anti-collision guardrail 8 is used for easy installation, reducing the opening on the bridge cantilever and facilitating construction.

[0091] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
