Description

Technical Field

[0001] This invention relates to the field of building structure technology, specifically to a foundation deformation adaptive rail bearing beam anti-fracture connection structure. Background Technology

[0002] During the construction of the tunnel boring machine (TBM) end shaft area, the gantry crane track beams mostly adopt a combination structure of reinforced concrete beams and steel box girders. In the TBM end shaft area, due to the local expansion of the retaining wall of the foundation pit, it is necessary to set up steel box girders to span the expanded section and connect with the reinforced concrete track beams on both sides.

[0003] Currently, the industry standard solution is rigid welding connection, which involves pre-embedding steel plates at the ends of reinforced concrete beams and welding the ends of steel box girders to the pre-embedded steel plates. However, the above-mentioned existing technologies all have the following shortcomings: the welding connection completely fixes the steel box girder to the concrete beam, and the additional bending moment generated by uneven foundation heave directly acts on the weld; it increases the risk of uneven rail surface, resulting in increased wheel pressure impact during gantry crane operation; the maintenance cost is high and the difficulty is great; and the safety risks are uncontrollable.

[0004] Therefore, the present invention provides a foundation deformation adaptive anti-fracture connection structure for rail bearing beams. Summary of the Invention

[0005] The purpose of this invention is to provide a foundation deformation adaptive anti-fracture connection structure for rail bearing beams to solve the problems mentioned in the background art.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a foundation deformation adaptive type rail bearing beam anti-fracture connection structure, including a reinforced concrete beam and a steel box beam, and also including a hinge mechanism, an anti-loosening mechanism and a marking mechanism;

[0007] A hinge mechanism is provided between the reinforced concrete beam and the steel box girder. The hinge mechanism includes a rotating component provided between the reinforced concrete beam and the steel box girder. A filling component is provided between the reinforced concrete beam and the steel box girder.

[0008] An anti-loosening mechanism is disposed between the reinforced concrete beam and the hinge mechanism. The anti-loosening mechanism includes a support component disposed on the reinforced concrete beam, a guide component disposed on the support component, and an adjustment component disposed between the support component and the guide component.

[0009] A marking mechanism is disposed between the steel box girder and the support assembly. The marking mechanism includes an abutment component disposed on the steel box girder and the support assembly. The support assembly and the abutment component are jointly provided with a misalignment visible component.

[0010] Furthermore, the rotating assembly includes a box-shaped steel component fixedly installed on a reinforced concrete beam. Two first connecting plates are fixedly installed on the box-shaped steel component. A second connecting plate is fixedly installed on the steel box beam and fits between the two first connecting plates. A hinge bolt is slidably installed between the two first connecting plates and the second connecting plate. An anti-loosening nut is threaded onto the hinge bolt.

[0011] Furthermore, the filling component includes cross anchor bars embedded in the reinforced concrete beam, and the steel box girder, box-shaped steel component, first connecting plate and second connecting plate are filled with filling mortar.

[0012] Furthermore, the support assembly includes a support plate fixedly installed on a reinforced concrete beam, a turntable rotatably installed on the inner side of the support plate, a connecting column slidably installed on the turntable, a nut sleeve fixedly installed on the connecting column, and a spring connecting the turntable and the nut sleeve.

[0013] Furthermore, the guide assembly includes an annular shell fixedly mounted on a support plate, on which a slider is slidably mounted.

[0014] Furthermore, the adjustment assembly includes a semicircular block fixedly mounted on a connecting column, a first central block rotatably mounted on the semicircular block, a movable arm fixedly mounted on the first central block, and a handle fixedly mounted on the movable arm.

[0015] Furthermore, a second center block is fixedly installed on the movable arm, and a connecting block that is fixed to the slider is rotatably installed on the second center block.

[0016] Furthermore, the abutment assembly includes a fixing plate fixedly installed on the steel box girder, an abutment block fixedly installed on the fixing plate, and an abutment ring that fits against the abutment block fixedly installed on the support plate.

[0017] Furthermore, the misaligned visual component includes a pointer fixedly mounted on a fixed plate, and an arc-shaped toothed plate adapted to the pointer is fixedly mounted on the support plate.

[0018] The beneficial effects of this invention are:

[0019] (1) By setting a first connecting plate and a second connecting plate, the relative rotation at the hinge point absorbs the energy of the foundation deformation, thereby reducing the bending moment transmitted to the node. The cross anchor bars convert the shear force into the tensile force of the steel bars, and with the mortar extrusion friction, the shear bearing capacity of the node is improved.

[0020] (2) By pulling the handle, the present invention enables the movable arm to rotate around the second center block, and the movable arm to move the nut sleeve through the first center block, the semicircular block and the connecting column, so that the nut sleeve can compress the spring. By moving the handle, the handle can move the slider along the inner side of the annular shell through the movable arm, the second center block and the connecting block, and the movable arm can rotate the turntable through the first center block, the semicircular block, the connecting column, the nut sleeve and the spring to adjust the angle of the nut sleeve so that the angle of the nut sleeve can be adapted to the hinge bolt. By releasing the handle, the spring can use its own elasticity to move the nut sleeve, so that the nut sleeve can be fitted on the hinge bolt and abut against and limit the hinge bolt, thereby improving the stability of the hinge bolt and reducing the probability of the hinge bolt loosening.

[0021] (3) In this invention, when the steel box girder moves, the steel box girder can move by driving the abutment block to fit the abutment ring through the fixing plate. The fixing plate can drive the pointer to move, and the staff can provide visual information about the scale misalignment based on the arc toothed plate pointed to by the pointer.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1-7 As shown, the foundation deformation adaptive type anti-fracture connection structure of the rail bearing beam of the present invention includes a reinforced concrete beam 1 and a steel box beam 2, and also includes a hinge mechanism, an anti-loosening mechanism and a marking mechanism. The hinge mechanism is set between the reinforced concrete beam 1 and the steel box beam 2. The hinge mechanism includes a rotating component set between the reinforced concrete beam 1 and the steel box beam 2. A filling component is set between the reinforced concrete beam 1 and the steel box beam 2. The rotating component includes a box-shaped steel member 3 fixedly installed on the reinforced concrete beam 1. Two first connecting plates 4 are fixedly installed on the box-shaped steel member 3. A second connecting plate 5 is fixedly installed on the steel box beam 2 and fits between the two first connecting plates 4. A hinge bolt 6 is slidably installed between the two first connecting plates 4 and the second connecting plate 5. An anti-loosening nut 7 is threaded on the hinge bolt 6. The filling component includes cross anchor bars 8 built into the reinforced concrete beam 1. The steel box beam 2, the box-shaped steel member 3, the first connecting plates 4 and the second connecting plates 5 are filled with filling mortar 9.

[0033] Specifically, by setting the first connecting plate 4 and the second connecting plate 5, the relative rotation at the hinge absorbs the energy of the foundation deformation, thereby reducing the bending moment transmitted to the node. The cross anchor bars 8 convert the shear force into the tensile force of the steel bars, and with the mortar extrusion friction, the shear bearing capacity of the node is improved.

[0034] In this embodiment, an anti-loosening mechanism is disposed between the reinforced concrete beam 1 and the hinge mechanism. The anti-loosening mechanism includes a support assembly disposed on the reinforced concrete beam 1, a guide assembly disposed on the support assembly, and an adjustment assembly disposed between the support assembly and the guide assembly. The support assembly includes a support plate 10 fixedly installed on the reinforced concrete beam 1, a turntable 11 rotatably mounted on the inner side of the support plate 10, a connecting column 12 slidably mounted on the turntable 11, and a nut sleeve 13 fixedly mounted on the connecting column 12. The turntable 11 and the nut sleeve 13 are connected... A spring 14 is connected between the two parts. The guide assembly includes an annular shell 22 fixedly mounted on the support plate 10. A slider 21 is slidably mounted on the annular shell 22. The adjustment assembly includes a semi-circular block 15 fixedly mounted on the connecting column 12. A first center block 16 is rotatably mounted on the semi-circular block 15. A movable arm 17 is fixedly mounted on the first center block 16. A handle 18 is fixedly mounted on the movable arm 17. A second center block 19 is fixedly mounted on the movable arm 17. A connecting block 20 fixed to the slider 21 is rotatably mounted on the second center block 19.

[0035] Specifically, by pulling the handle 18, the handle 18 can drive the movable arm 17 to rotate around the second center block 19. This allows the movable arm 17 to move the nut sleeve 13 via the first center block 16, the semicircular block 15, and the connecting post 12, thus compressing the spring 14. Moving the handle 18 allows the handle 18 to drive the slider 21 to move along the inner side of the annular shell 22 via the movable arm 17, the second center block 19, and the connecting block 20, thus allowing the movable arm 17 to... The turntable 11 can be rotated by the first central block 16, the semicircular block 15, the connecting column 12, the nut sleeve 13 and the spring 14 to adjust the angle of the nut sleeve 13 so that the angle of the nut sleeve 13 can be adapted to the hinge bolt 6. When the handle 18 is released, the spring 14 can use its own elastic force to drive the nut sleeve 13 to move, so that the nut sleeve 13 can be fitted on the hinge bolt 6 to abut and limit the hinge bolt 6, thereby improving the stability of the hinge bolt 6 and reducing the probability of the hinge bolt 6 loosening.

[0036] In this embodiment, the marking mechanism is disposed between the steel box girder 2 and the support assembly. The marking mechanism includes an abutment component disposed on the steel box girder 2 and the support assembly. The support assembly and the abutment component are jointly provided with a misalignment visibility component. The abutment component includes a fixing plate 24 fixedly installed on the steel box girder 2. An abutment block 25 is fixedly installed on the fixing plate 24. An abutment ring 23 that fits against the abutment block 25 is fixedly installed on the support plate 10. The misalignment visibility component includes a pointer 26 fixedly installed on the fixing plate 24. An arc-shaped toothed plate 27 that matches the pointer 26 is fixedly installed on the support plate 10.

[0037] Specifically, when the steel box girder 2 moves, the steel box girder 2 can move by the fixed plate 24 driving the abutment block 25 to fit against the abutment ring 23. The fixed plate 24 can drive the pointer 26 to move, and the staff can see the scale misalignment based on the arc-shaped toothed plate 27 pointed to by the pointer 26.

[0038] Working principle: By setting the first connecting plate 4 and the second connecting plate 5, the relative rotation at the hinge absorbs the energy of foundation deformation, reducing the bending moment transmitted to the node. The cross anchor bars 8 convert the shear force into the tensile force of the steel bars, which, together with the mortar extrusion friction, improves the shear bearing capacity of the node. By pulling the handle 18, the handle 18 can drive the movable arm 17 to rotate around the second center block 19. The movable arm 17 can then drive the nut sleeve 13 to move through the first center block 16, the semicircular block 15, and the connecting column 12. This allows the nut sleeve 13 to compress the spring 14. By moving the handle... 18. The handle 18 can drive the slider 21 to move along the inner side of the annular shell 22 through the movable arm 17, the second center block 19 and the connecting block 20. The movable arm 17 can drive the turntable 11 to rotate through the first center block 16, the semicircular block 15, the connecting column 12, the nut sleeve 13 and the spring 14 to adjust the angle of the nut sleeve 13 so that the angle of the nut sleeve 13 can be adapted to the hinge bolt 6. When the handle 18 is released, the spring 14 can use its own elastic force to drive the nut sleeve 13 to move so that the nut sleeve 13 can be fitted on the hinge bolt 6 and abut and limit the hinge bolt 6.

[0039] When the steel box girder 2 moves, the steel box girder 2 can move by the fixed plate 24 driving the abutment block 25 to fit against the abutment ring 23. The fixed plate 24 can drive the pointer 26 to move, and the staff can see the scale misalignment by referring to the arc toothed plate 27 pointed to by the pointer 26.
