Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bridge supports, in particular to a U-shaped anti-falling beam integrated support suitable for railway bridges with different slopes. Background Art
[0002] Under the action of external forces (such as earthquakes, wind, car impact, etc.), the beam of the bridge structure will be displaced on the supporting structure. In order to prevent the beam from displacing and falling, an anti-falling beam structure is set between the beam and the pier to limit the displacement of the beam. The anti-falling beam structure is usually used together with the support. The conventional anti-falling beam device and the support are two components, which have high requirements for the installation space. The more advanced one is the integrated structure of the anti-falling beam and the support.
[0003] At present, the anti-falling beam device structure in the integrated structure of the domestic support and anti-falling beam is mainly block type and cable type. However, whether it is a block type or a cable type anti-falling beam structure, it is necessary to make certain modifications to the structure of the support body itself, which is troublesome to design and produce, and not economical. Therefore, the new U-shaped steel anti-falling beam structure has received widespread attention in the market for its simple structure and superior performance. However, bridges sometimes have slopes, and the conventional method of adding a slope adjustment pad at the bottom of the beam not only has higher requirements for the installation height of the support, but also adds a component, which not only affects the installation efficiency, but also increases the economic cost.
[0004] How to reasonably adjust the slope so that the upper surface of the support can completely fit with the bottom surface of the sloped beam during installation, and the lower surface of the support is horizontal, without increasing the difficulty and cost of construction is a key technology that we urgently need to study and solve. Utility Model Content
[0005] In view of the problems described in the background technology, the purpose of the utility model is to provide a U-shaped anti-fall beam integrated support which does not require a slope pad, does not change the installation height of the bottom of the beam, and can adapt to different slopes.
[0006] In order to achieve the above-mentioned purpose, the U-shaped anti-fall beam integrated support designed by the utility model comprises a support body; the top of the support body is an upper support plate connected to the beam body embedded component, and the bottom is a lower support plate connected to the bridge pier; the upper surface of the U-shaped steel is connected to the bottom surface of the beam body embedded component through a first connecting piece, and the lower surface is connected to the top surface of the lower support plate through a second connecting piece;
[0007] The top surface of the upper support plate is provided with a first inclined surface, and the slope and direction of the first inclined surface are consistent with the slope of the beam body;
[0008] The axis of the first connecting member is perpendicular to the bottom surface of the beam body embedded component, so that the U-shaped steel is in surface contact with the beam bottom embedded component.
[0009] Preferably, the axis of the second connecting member is perpendicular to the bottom surface of the lower support plate, so that the U-shaped steel is in surface contact with the lower support plate.
[0010] Further preferably, the U-shaped steel is provided with a countersunk hole adapted to the second connecting member, and the mounting surface of the countersunk hole and the second connecting member are parallel to the bottom surface of the lower support plate.
[0011] As a preferred solution, the top surface of the lower support plate is provided with a second inclined surface, and the slope size and direction of the second inclined surface are consistent with the slope of the beam body.
[0012] Preferably, the support body is a spherical support.
[0013] The beneficial effects of the utility model are as follows: compared with the existing method of adding a slope adjustment pad for slope adjustment, the slope adjustment scheme of the utility model does not increase the installation space of the bottom of the beam, and reduces a component for the installation of a support, which not only increases the work efficiency but also is more economical. At the same time, the length of the bolt is also reduced, avoiding the problem of difficulty in removing the bolt.
[0014] Compared with the prior art, the utility model has the following specific advantages:
[0015] 1. Adapt to bridges with different slopes: By designing the first inclined surface and the second inclined surface on the top surface of the upper bearing plate and the top surface of the lower bearing plate, the bearing can adapt to beams with different slopes, thereby improving the versatility and adaptability of the bearing.
[0016] 2. Simplify the installation process: Since the axis of the first connecting piece is perpendicular to the bottom surface of the embedded component of the beam body, and the axis of the second connecting piece is perpendicular to the bottom surface of the lower support plate, this design enables surface contact between the U-shaped steel and the embedded component at the bottom of the beam and the lower support plate, which simplifies the installation process and improves installation efficiency.
[0017] 3. Improve structural stability: The surface contact design between the U-shaped steel and the embedded components of the beam body and the lower support plate increases the contact area, thereby improving the stability and bearing capacity of the entire structure.
[0018] 4. Optimize the design of the connector: by setting a countersunk hole adapted to the second connector on the U-shaped steel, and making the mounting surface of the countersunk hole and the second connector parallel to the bottom surface of the lower support plate, this design can ensure that the installation of the connector is more accurate and stable.
[0019] 5. Reduce additional accessories: Since the support body can adapt to the slope of the beam, there is no need to add additional slope adjustment pads, which reduces the number of installation accessories and reduces material and maintenance costs.
[0020] 6. Keep the support height unchanged: Even when the slope is adjusted, the support height remains unchanged, which means that there is no need to change the installation height of the bottom of the beam, thereby reducing changes to the existing bridge structure and reducing construction difficulty.
[0021] 7. Spherical bearing design: The preferred spherical bearing body design provides greater flexibility and adjustment range, allowing the bearing to be fine-tuned in multiple directions to adapt to different installation conditions and requirements.
[0022] 8. Improve economic efficiency: By reducing additional accessories and simplifying the installation process, the utility model not only improves construction efficiency, but also reduces the overall construction and maintenance costs, and has better economic efficiency.
[0023] 9. Enhanced safety: By ensuring the surface contact between the U-shaped steel and the embedded components at the bottom of the beam and the lower support plate, the safety of the entire structure is enhanced and the potential risks caused by unstable connections are reduced.
[0024] To sum up, the U-shaped anti-fall beam integrated support design of the utility model achieves adaptability to beams of different slopes through its unique structure and connection method, while simplifying the installation process, improving the stability and safety of the structure, and has significant technical and economic advantages.

[0030] The following is a further detailed description of the technical solution (including the preferred technical solution) of the present utility model by means of the accompanying drawings and by listing some optional embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.
[0031] like Figures 1 to 5 As shown, the U-shaped anti-fall beam integrated support designed by the utility model includes a support body 1; the top of the support body 1 is an upper support plate 3 connected to the beam body embedded component 2, and the bottom is a lower support plate 4 connected to the pier; the upper surface of the U-shaped steel 5 is connected to the bottom surface of the beam body embedded component 2 through a first connecting member 6, and the lower surface is connected to the top surface of the lower support plate 4 through a second connecting member 7; the top surface of the upper support plate 3 is provided with a first inclined surface 31, and the slope size and direction of the first inclined surface 31 are consistent with the slope of the beam body; the axis of the first connecting member 6 is perpendicular to the bottom surface of the beam body embedded component 2, so that the U-shaped steel 5 is in surface contact with the beam bottom embedded component 2.
[0032] In some optional embodiments of the present invention, the support body 1 is a spherical support.
[0033] In this embodiment, the top surface of the upper bearing plate of the spherical bearing is designed to have a sloped structure, and the size and direction of the slope are consistent with the slope of the beam body, so that the top surface of the upper bearing plate 3 fits the bottom of the beam.
[0034] In some optional embodiments of the present invention, the top surface of the lower support plate 4 is provided with a second inclined surface 41 , and the slope size and direction of the second inclined surface 41 are consistent with the slope of the beam body.
[0035] In some optional embodiments of the present invention, the axis of the second connecting member 7 is perpendicular to the bottom surface of the lower support plate 4, so that the U-shaped steel 5 is in surface contact with the lower support plate 4.
[0036] Preferably, the U-shaped steel 5 is provided with a countersunk hole 8 adapted to the second connecting member 7 , and the countersunk hole 8 and the mounting surface 9 of the second connecting member are parallel to the bottom surface of the lower support plate 4 .
[0037] When the beam body has a slope, the upper support plate 3 is designed to be a wedge-shaped structure with a slope, so that the upper surface of the upper support plate 3 and the embedded component 2 at the bottom of the beam are in "surface-to-surface" contact. At this time, the upper surface of the U-shaped steel 5 and the embedded component 2 at the bottom of the beam are also in "surface-to-surface" contact, and the lower surface of the U-shaped steel 5 and the lower support plate 4 are in "line-surface" contact. In order to ensure that the lower surface of the U-shaped steel 5 and the lower support plate 4 are also in "surface-to-surface" contact, the part connecting the lower support plate 4 and the U-shaped steel 5 is also made into a structure with a slope like the upper support plate 3. Therefore, the U-shaped steel 5 is placed on the support at an angle, but the anchor on the top of the support pier is installed perpendicular to the bottom surface of the lower support plate 4. In order to prevent the bolt - the second connecting member 7 from having "point-to-surface" contact with the U-shaped steel 5, the bolt hole at the lower end of the U-shaped steel 5 is also designed to have a sloped structure. When the U-shaped steel is placed at an angle, the slope surface of the bolt hole will become a horizontal surface, so that the bolt and the bolt hole at the lower end of the U-shaped steel are also in "surface-to-surface" contact.
[0038] The surface contact between the U-shaped steel 5 and the beam body embedded component 2 can ensure good contact between the U-shaped steel 5 and the beam body to provide sufficient supporting force and stability.
[0039] The upper end 51 of the U-shaped steel 5 of the utility model is connected to the bottom surface of the beam embedded component 2 through the first connecting member 6. In order to achieve "surface-to-surface" contact, the top surface of the upper support plate 3 is designed with a first inclined surface 31 consistent with the slope of the beam body, so that when the U-shaped steel 5 is placed on the upper support plate 3, its upper surface can fit closely with the bottom surface of the beam embedded component 2 to form a large contact surface. In this way, the bearing capacity of the support can be improved, local stress concentration can be reduced, and the service life of the support can be extended.
[0040] The surface contact between the U-shaped steel 5 and the lower bearing plate 4 can ensure the stability of the connection between the U-shaped steel 5 and the bridge pier, while allowing the bearing to adapt to the slope of the beam body.
[0041] The lower end 52 of the U-shaped steel 5 of the utility model is connected to the top surface of the lower support plate 4 through the second connecting member 7. In order to achieve "surface-to-surface" contact, the top surface of the lower support plate 4 is designed with a second inclined surface 41 that is consistent with the slope of the beam body. In this way, when the U-shaped steel 5 is in an inclined state, its lower surface is tightly fitted with the top surface of the lower support plate 4. Through this design, it can be ensured that even if the beam body has a slope, the U-shaped steel 5 can maintain a stable connection with the lower support plate 4, thereby improving the stability and reliability of the entire support.
[0042] In addition, in order to further ensure the stability of the "surface-to-surface" contact, a countersunk hole 8 adapted to the second connecting member 7 is also provided on the U-shaped steel 5. The design of the countersunk hole 8 makes the mounting surface 9 of the second connecting member 7 parallel to the bottom surface of the lower support plate 4. In this way, even if the U-shaped steel 5 is installed at an angle, the second connecting member 7 can achieve "surface-to-surface" contact with the lower surface of the U-shaped steel 5.
[0043] Through these "face-to-face" contact designs, the U-shaped anti-fall beam integrated support of the utility model can better adapt to bridge structures with different slopes, while providing higher stability and safety and reducing potential risks caused by unstable connections.
[0044] It is easy for those skilled in the art to understand that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, combinations, replacements, improvements, etc. made within the spirit and principles of the present invention are included in the protection scope of the present invention.
