Description

Technical Field

[0001] This utility model relates to the field of prefabricated bridge technology; more specifically, it relates to a segmental prefabricated bridge steel component. Background Technology

[0002] Segmental precast bridges are bridge structures built using prefabrication technology. The bridge segments are manufactured in advance in a factory and then assembled on-site. This method significantly shortens construction time. The crossbeams and longitudinal beams are the main load-bearing components of the bridge, supporting the bridge deck and ribs. Crossbeams are typically located below the bridge deck and distributed along the length of the bridge; longitudinal beams are perpendicular to the crossbeams and are located in the center or on either side of the bridge deck.

[0003] Currently, in the use of existing segmental precast bridge steel components, the lack of positioning structures at the connection points between some existing precast crossbeams and longitudinal beams makes installation and docking difficult and prone to misalignment. Furthermore, some existing precast longitudinal beams have weak lateral support capabilities, which may affect the overall stability of the bridge. Therefore, there is an urgent need for a segmental precast bridge steel component to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a segmental prefabricated bridge steel component to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a segmental prefabricated bridge steel component, comprising:

[0006] The longitudinal beam structure includes a longitudinal beam body, a limiting plate, a fixing seat, a positioning seat and positioning holes, and the limiting plate is provided in two sets, and the positioning holes are provided in multiple sets.

[0007] A crossbeam structure, comprising a crossbeam body, a positioning groove and positioning rods, wherein four sets of positioning rods are provided, and the lower surface of the crossbeam body is attached to the upper surface of the fixing seat;

[0008] The support structure includes a connecting ring and a fixing plate, and the fixing plate is provided in two sets, and the inner surface of the connecting ring is attached to the outer surface of the upper end of the longitudinal beam body.

[0009] Preferably, the two sets of limiting plates are respectively fixedly connected to the outer surface of the upper end of the longitudinal beam body, the fixing seat is fixedly connected to the upper surface of the longitudinal beam body, and the positioning seat is fixedly connected to the upper surface of the fixing seat. The positioning seat can effectively position the beam structure during installation.

[0010] Preferably, grouting cavities are formed inside the outer surfaces of all four sides of the positioning seat, and the four sets of positioning holes are respectively formed inside the positioning seat. The setting of four sets of positioning holes can further improve the positioning accuracy during the installation of the beam structure.

[0011] Preferably, a positioning groove is provided inside the lower surface of the main body of the crossbeam, and four sets of positioning rods are respectively fixedly connected to the upper surface inside the positioning groove. Furthermore, a grouting hole is provided inside the upper surface of the main body of the crossbeam, so that workers can later pour concrete into the positioning groove through the grouting hole.

[0012] Preferably, the inner surface of the positioning groove is attached to the outer surface of the positioning seat, and the height of the positioning groove is greater than the height of the positioning seat. Multiple sets of positioning rods are respectively inserted into the interior of multiple sets of positioning holes. After the interior of the positioning groove is attached to the outer surface of the positioning seat, the four sets of positioning rods will be respectively inserted into the interior of the four sets of positioning holes. At this time, the beam structure can be limited, which can prevent the beam structure from shifting during the later concrete grouting.

[0013] Preferably, the outer surfaces of the upper and lower ends of the connecting ring are respectively attached to the surfaces of the opposite ends of the two sets of limiting plates, and connecting seats are fixedly connected to the outer surfaces of both sides of the connecting ring. Support rods are hinged to the interior of the two sets of connecting seats, and support seats are hinged to the interior of one end of the two sets of support rods. The lower surfaces of the two sets of fixing plates are fixedly connected to one end of the two sets of support seats. In use, the connecting ring can be connected to the outer surface of the longitudinal beam body by bolts. The position of the connecting ring can be restricted by the setting of the two sets of limiting plates, and the connecting ring can be effectively supported, thereby improving the overall stability of the support structure during use.

[0014] Preferably, the upper surfaces of the two sets of fixing plates are respectively attached to both ends of the lower surface of the crossbeam body. In use, the two sets of fixing plates can be connected to both ends of the lower surface of the crossbeam body by bolts. At this time, the support structure can form a triangular support between the crossbeam body and the longitudinal beam body, thereby effectively improving the lateral support capacity of the longitudinal beam body to the crossbeam body.

[0015] The technical effects and advantages of this utility model are as follows: This utility model uses a positioning seat to position the crossbeam structure during installation, making it easier for workers to connect the positioning groove and the positioning seat. After the inner surface of the positioning groove is in contact with the outer surface of the positioning seat, four sets of positioning rods are inserted into the four sets of positioning holes, which can limit the crossbeam structure. Then, workers can inject concrete into the positioning groove through the grouting hole. Finally, the concrete will fill the four sets of grouting cavities and the gap between the positioning seat and the upper end of the positioning groove. This design can effectively reduce the difficulty of connecting the longitudinal beam structure and the crossbeam structure during installation and prevent the crossbeam structure from shifting during connection.

[0016] Bolts can be used to connect the connecting ring to the outer surface of the longitudinal beam body. Then, pull the two sets of fixing plates to fit the two ends of the lower surface of the crossbeam body respectively, and fix them with bolts. At this time, the support structure can form a triangular support between the crossbeam body and the longitudinal beam body. This design can effectively improve the lateral support capacity of the longitudinal beam body to the crossbeam body, thereby improving the overall stability of the bridge to a certain extent. Moreover, its overall structure is simple and reasonable, highly practical, and easy to promote and apply. Attached Figure Description

In addition, the forms of the various structures described in the following embodiments are merely illustrative. The segmental prefabricated steel bridge components involved in this utility model are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1

[0024] like Figures 1 to 4 As shown, this utility model provides a segmental prefabricated bridge steel component, including: a longitudinal beam structure 1, the longitudinal beam structure 1 including a longitudinal beam body 11, a limiting plate 12, a fixing seat 13, a positioning seat 14 and positioning holes 15, and the limiting plate 12 is provided in two sets, and the positioning holes 15 are provided in multiple sets. The two sets of limiting plates 12 are respectively fixedly connected to the outer surface of the upper end of the longitudinal beam body 11, the fixing seat 13 is fixedly connected to the upper surface of the longitudinal beam body 11, the positioning seat 14 is fixedly connected to the upper surface of the fixing seat 13, and the four outer surfaces of the positioning seat 14 are provided with grouting cavities 16. The four sets of positioning holes 15 are respectively opened in the interior of the positioning seat 14. The positioning seat 14 can play an effective positioning role during the installation of the crossbeam structure 2, and the four sets of positioning holes 15 can further improve the positioning accuracy of the crossbeam structure 2 during installation.

[0025] The crossbeam structure 2 includes a crossbeam body 21, a positioning groove 22, and positioning rods 23, with four sets of positioning rods 23. The lower surface of the crossbeam body 21 is attached to the upper surface of the fixing seat 13. The positioning groove 22 is formed inside the lower surface of the crossbeam body 21, and the four sets of positioning rods 23 are respectively fixedly connected to the upper surface inside the positioning groove 22. Grouting holes 24 are formed inside the upper surface of the crossbeam body 21. The inner surface of the positioning groove 22 is attached to the outer surface of the positioning seat 14, and the height of the positioning groove 22 is greater than the height of the positioning seat 14. The multiple sets of positioning rods 23 are respectively inserted into the interior of multiple sets of positioning holes 15. The crossbeam structure 2 can be positioned through the positioning seat 14. The installation serves a positioning function, making it easier for workers to align the positioning groove 22 with the positioning seat 14. After the inner surface of the positioning groove 22 is in contact with the outer surface of the positioning seat 14, the four sets of positioning rods 23 will be inserted into the four sets of positioning holes 15 respectively. At this time, it can limit the position of the crossbeam structure 2. Then, workers can inject concrete into the positioning groove 22 through the grouting hole 24. Finally, the concrete will fill the four sets of grouting cavities 16 and the gap between the positioning seat 14 and the upper end of the positioning groove 22. This design can effectively reduce the difficulty of aligning the longitudinal beam structure 1 and the crossbeam structure 2 during installation and can prevent the crossbeam structure 2 from shifting during alignment. Example 2

[0026] like Figures 1 to 5 As shown, this embodiment also proposes a support structure 3, which includes a connecting ring 31 and a fixing plate 35. Two sets of fixing plates 35 are provided. The inner surface of the connecting ring 31 is attached to the outer surface of the upper end of the longitudinal beam body 11. The outer surfaces of the upper and lower ends of the connecting ring 31 are respectively attached to the surfaces of opposite ends of the two sets of limiting plates 12. Connecting seats 32 are fixedly connected to the outer surfaces of both sides of the connecting ring 31. Support rods 33 are hinged to the interior of both sets of connecting seats 32. Support seats 34 are hinged to the interior of one end of each set of support rods 33. The lower surfaces of the two sets of fixing plates 35 are fixedly connected to one end of each set of support seats 34. The upper surfaces of the two sets of fixing plates 35 are respectively attached to the lower surface of the transverse beam body 21. At both ends, the connecting ring 31 can be connected to the outer surface of the longitudinal beam body 11 by bolts. The position of the connecting ring 31 can be restricted by the setting of two sets of limiting plates 12, and the connecting ring 31 can be effectively supported, thereby improving the overall stability of the support structure 3 during use. Then, the two sets of fixing plates 35 are pulled to fit with the two ends of the lower surface of the crossbeam body 21 and fixed by bolts. At this time, the support structure 3 can form a triangular support between the crossbeam body 21 and the longitudinal beam body 11. This design can effectively improve the lateral support capacity of the longitudinal beam body 11 to the crossbeam body 21, thereby improving the overall stability of the bridge to a certain extent.

[0027] Working principle: When using the equipment, first install the longitudinal beam body 11 in a suitable position, then lift the crossbeam structure 2, and then fit the positioning groove 22 onto the outer surface of the positioning seat 14. At the same time, the four sets of positioning rods 23 will be inserted into the four sets of positioning holes 15. Then, the lower surface of the crossbeam body 21 will be in contact with the upper surface of the fixing seat 13. Then, concrete will be injected into the positioning groove 22 through the grouting hole 24. Then, the concrete will fill the four sets of grouting chambers 16 and the gap between the positioning seat 14 and the upper end of the positioning groove 22. At this time, the installation between the longitudinal beam structure 1 and the crossbeam structure 2 can be completed.

[0028] Next, the connecting ring 31 is connected to the outer surface of the longitudinal beam body 11 by bolts. Then, the two sets of fixing plates 35 are pulled to fit against the two ends of the lower surface of the crossbeam body 21 and fixed by bolts. At this time, the support structure 3 can form a triangular support between the crossbeam body 21 and the longitudinal beam body 11. The above is the complete working principle of this utility model.
