Description

Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to a pier-beam connection structure. Background Art

[0002] When designing pedestrian landscape bridges, curved steel structure bridges are often designed to make the structure more beautiful and adapt to the terrain to reduce the project cost. However, there is a problem of overturning for curved (small radius) steel box pedestrian bridges. To prevent the above problem, it is necessary to set a consolidation pier at the mid-span position. The current method is to weld the top of the single-column pier to the bottom surface of the steel box floor, and weld a stiffening plate at the interface to prevent local stress concentration.

[0003] Welding the top of the single-column pier to the bottom of the steel box chamber floor and welding a stiffening plate at the interface can solve the overturning problem of curved (small radius) steel structure bridges to a certain extent. However, the connection between the steel structure box girder and the steel pipe single-column pier is welded on site, and the quality of the weld is not easy to guarantee. In addition, the anti-corrosion coating can only be applied on site. Once the weld quality does not meet the requirements or the weld position is corroded by the environment, resulting in a decrease in the weld bearing capacity, the safety of pedestrians cannot be guaranteed.

[0035] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] In the embodiment of the utility model, the pier-beam connection structure can be used to connect the single-column pier and the first steel box chamber.

[0037] Combine the following Figures 1 to 7 , the pier-beam connection structure and the fruit and vegetable sorting machine provided in the embodiments of the present application are described in detail through specific embodiments.

[0038] The pier-beam connection structure 100 provided in one embodiment of the present invention comprises a single-column pier 10, a first steel box chamber 20 and a second steel box chamber 30. The single-column pier 10 is arranged on the ground; the first steel box chamber 20 is provided with a fixing hole 211, and the single-column pier 10 is passed through the first steel box chamber 20 through the fixing hole 211 and connected to the top plate 22 of the first steel box chamber 20; the second steel box chamber 30 is located on both sides of the first steel box chamber 20 and connected to the first steel box chamber 20.

[0039] Among them, regarding the above-mentioned first steel box chamber 20 and second steel box chamber 30, the first steel box chamber 20 and second steel box chamber 30 are a structural form for bearing bridge beams (beams), which are made of steel to form a box-shaped section, and its shape is usually similar to a box. The first steel box chamber 20 and the second steel box chamber 30 are made of steel, have high strength and rigidity, and can withstand the load requirements of long-span bridges. And by setting the first steel box chamber 20 and the second steel box as a box-shaped structure, the deformation of the bridge during use and the stress caused by the deformation can be effectively resisted.

[0040] In this embodiment, the first steel box chamber 20 and the second steel box chamber 30 are connected to each other, specifically, the second steel box chamber 30 is located on both sides of the first steel box chamber 20, and a plurality of first steel box chambers 20 and a plurality of second steel box chambers 30 are connected in sequence, so that a bridge-like structure is formed. The single column pier 10 is set on the ground, and a fixing hole 211 is opened on the first steel box chamber 20. The fixing hole 211 is opened on the bottom plate 21 of the first steel box chamber 20, so that the single column pier 10 can pass through the fixing hole 211 on the bottom plate 21 of the first steel box chamber 20 to enter the interior of the first steel box chamber 20 and connect with the top plate 22 of the first steel box chamber 20. Through such an arrangement, the single-column pier 10 is inserted into the fixing hole 211 on the bottom plate 21 of the first steel box chamber 20, so that the first steel box chamber 20 and the single-column pier 10 can be connected to each other, thereby achieving the purpose of fixing the first steel box chamber 20 on the single-column pier 10; and through the welding connection of the single-column pier 10 with the top plate 22 and the bottom plate 21 in the factory, the structure can be made more reliable and the overhead welding seams on site can be avoided. Specifically, during the welding process in the factory, the bottom plate can be rotated so that it is set upward, so that the single-column pier 10 is welded with the top plate 22 and the bottom plate 21, which can avoid the overhead welding connection of the single-column pier 10 with the top plate 22 and the bottom plate 21 after the installation process.

[0041] In some embodiments, the single-column pier 10 includes a main body 11 and a connecting portion 12, which are fixedly connected; the main body 11 is set on the ground, and the connecting portion 12 is passed through the fixing hole 211 in the first steel box chamber 20 and connected to the top plate 22 of the first steel box chamber 20.

[0042] The main body 11 and the connecting part 12 are connected, and the connecting part 12 can be inserted into the first steel box chamber 20 through the fixing hole 211 on the bottom plate 21 of the first steel box chamber 20, and the connecting part 12 abuts against the top plate 22 of the first steel box chamber 20 when in the first steel box chamber 20, so that the first steel box chamber 20 can be installed on the single column pier 10. More specifically, the diameter of the connecting part 12 is the same as the diameter of the main body 11, and the diameter of the connecting part 12 is the same as the diameter of the fixing hole 211, so as to prevent the first steel box chamber 20 from shaking under force after the single column pier 10 is inserted into the fixing hole 211.

[0043] The main body 11 is installed on the ground to support the first steel box chamber 20 above it.

[0044] In some embodiments, the connecting portion 12 and the main body 11 are both steel pipes, and the interiors of the connecting portion 12 and the main body 11 are hollow and interconnected; a casting hole 222 is opened on the top plate 22 of the first steel box chamber 20, and the position of the casting hole 222 corresponds to the position of the single-column pier 10, and external concrete can enter the connecting portion 12 and the main body 11 of the single-column pier 10 through the casting hole 222.

[0045] The main body 11 and the connecting part 12 are both made of steel pipe, so the single-column pier 10 is made of steel pipe. By using the single-column pier 10 made of steel pipe, it has high strength and rigidity, and can effectively bear the load of the bridge. And the hollow single-column pier 10 can make it lighter. A pouring hole 222 is opened on the top plate 22 of the first steel box chamber 20, and the position of the pouring hole 222 corresponds to the position of the single-column pier 10. External concrete can be poured into the single-column pier 10 through the pouring hole 222 to enhance the concrete filling inside the single-column pier 10 and further increase the strength. Through such a setting, on the one hand, through the pouring hole 222, external concrete can enter the single-column pier 10 to achieve uniform filling of concrete. In this way, it can ensure that the concrete inside the pier is evenly distributed and enhance the overall stability and durability of the structure. On the other hand, the pouring hole 222 provides convenience for the injection of concrete, and conventional pouring methods and equipment can be used for construction. This simplifies the construction process and improves construction efficiency.

[0046] In some embodiments, a third stiffening plate 23 and a fourth stiffening plate 24 are disposed inside the first steel box chamber 20 , and the third stiffening plate 23 and the fourth stiffening plate 24 are disposed perpendicular to each other.

[0047] Specifically, the third stiffening plate 23 is arranged on the side of the first steel box chamber 20, and the fourth stiffening plate 24 is arranged on the top surface of the first steel box chamber 20; or the third stiffening plate 23 is arranged on the top surface of the first steel box chamber 20, and the fourth stiffening plate 24 is arranged on the side of the first steel box chamber 20. By arranging the third stiffening plate 23 and the fourth stiffening plate 24 in the first steel box chamber 20, the rigidity and stability of the structure of the first steel box chamber 20 can be increased. The third stiffening plate 23 and the fourth stiffening plate 24 can withstand the tensile pressure between the components, reduce the deformation and displacement of the structure, and improve the overall strength of the structure. And the third stiffening plate 23 and the fourth stiffening plate 24 can disperse the load and stress to the adjacent components to reduce the situation of local stress concentration. Thereby, it plays a role in sharing the load and increasing the bearing capacity of the structure in the first steel box chamber 20. In addition, the third stiffening plate 23 and the fourth stiffening plate 24 connect and support each component in the steel box chamber, so that they can work together to form an integral structure. It provides support and connection under stress and load, ensuring the stability and safety of the structure.

[0048] In some embodiments, the top plate 22 includes a steel plate 221, which is detachably connected to the top plate 22, and the steel plate 221 can be covered on the casting hole 222. When it is necessary to cast the single-column pier 10, the steel plate 221 can be opened to expose the casting hole 222 to the outside, so that concrete can enter the single-column pier 10 through the casting hole 222, thereby filling the inside of the single-column pier 10 with concrete to enhance the structural strength of the single-column pier 10. When it is not necessary to cast the single-column pier 10, the steel plate 221 can be covered on the casting hole 222, so that the casting hole 222 is closed.

[0049] When the steel plate 221 is covered on the casting hole 222, the top plate 22 can be patched. Specifically, the steel plate 221 can be embedded in the top plate 22 as a part of the top plate 22 after the concrete is filled, providing additional strength and stability. It can increase the bearing capacity of the top plate 22 and make the single-column pier 10 more solid as a whole. In addition, the patching of the steel plate 221 can protect the top plate 22 and prevent the expansion and generation of concrete cracks. It can disperse the stress on the top plate 22, reduce stress concentration, and improve the durability and service life of the top plate 22. In addition, the steel plate 221 can be used to compensate for defects or uneven surfaces of the top plate 22. If the filled concrete has an uneven surface or unevenness, the use of the steel plate 221 for patching can make the surface of the top plate 22 smoother and more beautiful, and provide better conditions for use.

[0050] In some embodiments, the first stiffening plate 40 can be used as a structural element to increase the rigidity and strength between the connection portion 12 and the first steel box chamber 20, so that the structure of the single-column pier 10 and the first steel box chamber 20 in the direction along the bridge is more stable. The first stiffening plate 40 is located in the direction along the bridge (the direction along the bridge refers to the direction of the central axis of the bridge, which can also be understood as the direction of the water flow or the route direction), between the connection portion 12 and the first partition 25. The first stiffening plate 40 increases the stability of the entire structure by connecting with the connection portion 12 (single-column pier 10) and the first partition 25.

[0051] In some embodiments, the pier-beam connection structure 100 further includes a second stiffening plate 50, and the first steel box chamber 20 includes a web 26, and the web 26 and the connection portion 12 are connected in the transverse bridge direction (the transverse bridge direction refers to the direction perpendicular to the central axis of the bridge) by the second stiffening plate 50. The second stiffening plate 50 can be used to increase the rigidity and strength of the structural element between the connection portion 12 and the first steel box chamber 20, so that the structure of the single-column pier 10 and the first steel box chamber 20 in the transverse bridge direction is more stable. Specifically, the web 26 of the first steel box chamber 20 is connected to the second stiffening plate 50, and the second stiffening plate 50 is located in the transverse bridge direction, and the connection portion 12 and the web 26 are connected by the second stiffening plate 50. The second stiffening plate 50 can provide additional support and stability to enhance the connection between the connection portion 12 (single-column pier 10) and the first steel box chamber 20.

[0052] In some embodiments, the pier-beam connection structure 100 further includes a heightened stiffening plate 60, the second steel box chamber 30 includes a fifth stiffening plate 31, and the fifth stiffening plate 31 and the first stiffening plate 40 are connected through the heightened stiffening plate 60. The two ends of the heightened stiffening plate 60 have a certain height difference, and when the heightened stiffening plate 60 is connected to the fifth stiffening plate 31 of the second steel box chamber 30 and the other end is connected to the first stiffening plate 40, the bridge can have a curved surface shape, making the bridge more beautiful.
