Description

Technical Field

[0001] The invention relates to an assembled bridge connection structure, belonging to the technical field of assembled bridge connection structures. Background Art

[0002] Prefabricated bridges are different from traditional on-site construction methods. For prefabricated bridges, some or all of the components of the prefabricated bridge are processed and formed in a prefabricated component factory, and then transported to the construction site for hoisting and assembly into the bridge body.

[0003] After the prefabricated bridges are spliced, movable gaps will be left between two adjacent prefabricated bridges in sections. The main purpose of the movable gaps is to avoid fixing and splicing all the prefabricated bridges together, because fixing and splicing together will easily cause the prefabricated bridges to crack due to hard pulling. The segmented prefabricated bridges can independently perform shock absorption. It is common to use steel plates to connect the movable gaps of two adjacent prefabricated bridges. During use, because the steel plates are fixed, the two prefabricated bridges are raised and lowered at different times for a long time for shock absorption, which will cause the fixed connection of the steel plates to loosen and detach, seriously affecting the normal passage of vehicles. In response to the above shortcomings, the present invention proposes an prefabricated bridge connection structure. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a prefabricated bridge connection structure to solve the existing problems.

[0006] A further improvement is that the interval between two adjacent movable components is 8-12 cm.

[0009] A further improvement is that after the fitting groove and the sleeve head are fitted together, movable gaps remain on the left and right sides, and the spacing between the left and right movable gaps is 0.5-1.2 cm.

[0010] As a further improvement, each of the first reinforcement strips and each of the second reinforcement strips is made of steel bar material, the anti-tear layer is a steel wire mesh, and each of the reinforcement pads is made of iron material.

[0011] A further improvement is that a plurality of anti-slip protrusions are arranged at laterally intervals on the top surface of the top pad body, and a plurality of sunken screw holes corresponding one-to-one to the movable components are arranged at intervals on the top surface of the top pad body, and a plurality of movable grooves corresponding one-to-one to the movable components are arranged at intervals in the middle of the bottom surface of the top pad body, and the top pad body is made of rubber.

[0013] A further improvement is that the diameter of the bolt body is 1.5-3 cm smaller than the diameter of the two first through-holes, the diameter of the second through-holes is adapted to the diameter of the bolt body, the bolt head is in the shape of an elongated strip, and the gasket is in the shape of an elongated strip.

[0014] A further improvement is that the first bridge and the connecting side of the first bridge are both provided with precast connecting seats.

[0015] The beneficial effects of the present invention are: The present invention provides an assembled bridge connection structure, which is composed of a connection structure composed of a first connecting crossbeam, a second connecting crossbeam, a plurality of movable components and a top pad assembly structure.

Through the functional design of the above-mentioned connection structure, the connection structure will not loosen or tear when used in the movable gap between the two bridges, effectively solving the problem of hard pulling and loosening caused by the existing iron plate. The use effect of the present invention is better. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figures 1-8The present invention provides an assembled bridge connection structure: its structure includes a first bridge 1 and a first bridge 2, and a connection structure 3 is arranged flush on the top surface of the movable part between the first bridge 1 and the first bridge 2, and the connection structure 3 includes a first connecting beam 31 and a second connecting beam 32, and a plurality of movable components 33 are arranged at equal intervals between the first connecting beam 31 and the second connecting beam 32, and a top pad assembly 34 is arranged on the top surface between each movable component 33, each of the movable components 33 is composed of a first supporting component 331 and a second supporting component 332 through a hinged component 333. The top pad assembly 34 includes a top pad body 341, and a plurality of first reinforcing strips 342 and a plurality of second reinforcing strips 343 are laterally spaced on the front and rear sides of the top pad body 341, and an anti-tear layer 344 is arranged between each of the first reinforcing strips 342 and each of the second reinforcing strips 343, and a plurality of reinforcing pads 345 are embedded in the front and rear sides of the bottom of the top pad body 341.

[0019] The interval between two adjacent movable components 33 is 8-12 cm.

[0020] The first supporting member 331 is integrally formed by a first fixing seat 3311 and a first longitudinal beam 3312, and a first screw hole 3313 is opened on the top surface of the first longitudinal beam 3312, and a fitting groove 3314 is opened in the middle of the tail end of the first longitudinal beam 3312, and two first through-holes 3315 are opened on the left and right groove walls of the fitting groove 3314.

[0021] The second supporting member 332 is integrated with a second fixing seat 3321 and a second longitudinal beam 3322, and a second screw hole 3323 is provided on the top surface of the second longitudinal beam 3322, and a sleeve 3324 is provided at the tail end of the second longitudinal beam 3322 for movably fitting into the fitting groove 3314, and a second through hole 3325 is provided through the middle of the sleeve 3324.

[0022] After the fitting groove 3314 and the fitting head 3324 are fitted together, there is a movable gap on the left and right sides, and the distance between the left and right movable gaps is 0.5-1.2 cm.

[0023] Each of the first reinforcement strips 342 and each of the second reinforcement strips 343 is made of steel bars, the anti-tear layer 344 is a steel mesh, and each of the reinforcement pads 345 is made of iron.

[0024] The top surface of the top pad body 341 is laterally spaced with a plurality of anti-slip protrusions 3411, and the top surface of the top pad body 341 is spaced apart with a plurality of sunken screw holes 3412 corresponding one-to-one to the movable components 33, and the middle part of the bottom surface of the top pad body 341 is spaced apart with a plurality of movable grooves 3143 corresponding one-to-one to the movable components 33. The top pad body 341 is made of rubber.

[0025] The hinge member 333 is composed of a bolt 3331, a washer 3332, a spring 3333 and a nut 3334. The tail of the bolt 3331 is provided with an anti-drop hole 3335, and the anti-drop hole 3335 is inserted with a pin 3336 for locking the nut 3334.

[0026] The diameter of the bolt body of the bolt 3331 is 1.5-2 cm smaller than the diameter of the two first through-holes 3315 , and the diameter of the second through-hole 3325 is adapted to the diameter of the bolt body of the bolt 3331 . The bolt head of the bolt 3331 is in the shape of an elongated strip, and the gasket 3332 is in the shape of an elongated strip.

[0027] Working principle: When a vehicle travels on the first bridge 1 and the first bridge 2, the first bridge 1 and the first bridge 2 themselves will vibrate, and in this process, the first support member 331 and the second support member 332 will be driven to rise and fall at different frequencies, and the vibration lifting height interval is generally less than 1CM. Due to the 0.5-1.2cm movable gap left on the left and right sides after the fitting groove 3314 and the sleeve head 3324 are fitted together, there will be no collision between the first support member 331 and the second support member 332. When the first support member 331 and the second support member 332 rise and fall at different frequencies, the middle part of the top pad body 341 will be torsional and tensile deformed. However, since the anti-tear layer 344 is reinforced with a steel mesh, the top pad body 341 will not break after torsional deformation for a long time.

[0028] Furthermore, the primary purpose of each first reinforcing strip 342 and each second reinforcing strip 343 is to provide lateral support for the top pad body 341 between the two movable members 33 spaced 8-12 cm apart, preventing the top pad body 341 from sinking when pressed by a tire. Furthermore, the 8-12 cm spacing design meets the minimum tire width specifications for a vehicle, ensuring that when a wheel passes over the top surface of the top pad body 341, it will be supported by at least one movable member 33.

[0029] In addition, the bolt body diameter of the bolt 3331 is designed to be 1.5-2 cm smaller than the diameter of the two first through-holes 3315, so that the first support member 331 and the second support member 332 will not be stuck by the bolt 3331 when they are raised and lowered at different frequencies. The main purpose of the hinged member 333 is to create a longitudinal tension between the first support member 331 and the second support member 332 to prevent the first bridge 1 and the first bridge 2 from being displaced during long-term use, which would cause the active gap between the two adjacent prefabricated bridges to widen and the other end to shrink.

[0030] In addition, since the bolt head of the bolt 3331 is in the shape of an elongated strip and the gasket 3332 is in the shape of an elongated strip, in order to make the bolt body diameter of the bolt 3331 smaller than the diameter of the two first through-holes 3315 by 1.5-2 cm, a locking position can be formed. However, this will cause the horizontal height of the bolt 3331 and the gasket 3332 after installation to be higher than the top surface of the first support member 331 and the second support member 332. The design of each movable groove 3143 allows the hinged member 333 to move freely, and the hinged member 333 will not push the middle part of the bottom surface of the top pad body 341 upward.
