This technology discloses "a bridge pier and a bridge, wherein a pier seat is fixedly installed at the lower end of the pier, a support is fixedly installed at the upper end of the pier, and the bridge is fixedly installed on the upper end of the pier through the support. Grooves are provided at both ends of the bridge, and the inner cavity of the groove is provided with a gusset plate. The support includes a placement platform, a limit seat and a bridge ear. The limit seat is located at both ends of the placement platform, and the bridge ear is located on both sides of the placement platform. The lower end of the placement platform is a triangular structure and is fixedly connected to the upper end of the pier. The utility model uses a limit block and a limit seat. When the piers are docked, they are clamped on the upper end of the support, which facilitates the control of the placement length of the two ends of the bridge.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] like Figure 1 As shown:

[0025] A splicing device for highway bridge design application comprises a beam body 1.

[0026] In this embodiment: the existing {public announcement number}: CN211472111U discloses a bridge docking connection structure, and this patent discloses a bridge. The beam body 1 in this application document adopts the same technical means in this prior art. This technical means will not be described one by one here. For details about the improvement of this prior art, please refer to the disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the design is relatively simple when closing and splicing, so it is difficult to ensure its stability during the later use, which will cause certain safety hazards. At the same time, the device lacks the expansion joint required to cope with the expansion and contraction of the bridge. Cracks may occur during use and affect the overall service life." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve the above problems, A docking block 2 and card plate 3 are added on this basis.

[0027] More specifically:

[0028] like Figure 1 - Figure 5 As shown:

[0029] In combination with the above content: it also includes an A docking block 2, a card plate 3, a slide groove 4, a contraction spring 5, a B docking block 6, a card block 7 and a positioning spring 8 arranged on one side of the beam body 1, and the two ends of the beam body 1 are respectively fixedly provided with an A docking block 2 and a B docking block 6, the inner surface of the A docking block 2 is provided with a slide groove 4 slidably connected to the card plate 3, and one side of the surface of the card plate 3 is also fixedly connected to one end of the contraction spring 5, and the other end of the contraction spring 5 is fixedly connected to the inner surface of the A docking block 2, the surface of the B docking block 6 is also slidably connected with a card block 7, and the card block 7 is also engaged with the card plate 3, and the inner surface of the B docking block 6 is also provided with a positioning spring 8, and at the same time, the two ends of the positioning spring 8 are fixedly connected to the card block 7.

[0030] In this embodiment, when the beam bodies 1 need to be butt-jointed, the A butt-jointed block 2 on one side of the beam body 1 is oriented toward the direction of the B butt-jointed block 6 of the other beam body 1, and the two beam bodies 1 are butt-jointed. At this time, the A butt-jointed block 2 and the B butt-jointed block 6 are staggered and connected, and the card plate 3 provided on the surface of the A butt-jointed block 2 is connected to the card block 7, and the connection between the card plate 3 and the card block 7 promotes the card block 7 and the B butt-jointed block 6 to slide, thereby compressing the positioning spring 8 inside the B butt-jointed block 6. As the A butt-jointed block 2 and the B butt-jointed block 6 move further, the card plate 3 will The block 7 passes the position where the card block 7 is located, and the card block 7 will reset itself under the rebound of the positioning spring 8 and block the card plate 3 after there is no obstruction from the card plate 3. At this time, the docking work between the two beams 1 is completed. When the temperature changes and causes the bridge to shrink, tension will be generated between the beams 1 and 1, and stress will be generated between the card plate 3 and the card block 7 that remain in the engaged state, pulling the card plate 3 to slide in the slide groove 4 opened inside the A docking block 2. At this time, the card plate 3 and the A docking block 2 will compress the contraction spring 5 and buffer the space between the beams 1 and 1.

[0031] Going further:

[0032] In an optional embodiment, the shape of the clamping plate 3 is an isosceles trapezoidal column, and both side surfaces of the clamping plate 3 are inclined surfaces.

[0033] In this embodiment: the isosceles trapezoidal column-shaped clamping plate 3 can generate friction through the inclined surfaces on both sides and the clamping block 7 when the beam bodies 1 are docked with each other, and after further movement, it can push the clamping block 7 to move, thereby generating a clamping connection and completing the docking work.

[0034] Going further:

[0035] In an optional embodiment, the slide grooves 4 are symmetrically arranged on both sides of the inner surface of the A docking block 2 .

[0036] In this embodiment: the slide grooves 4 symmetrically arranged on both sides of the A docking block 2 can make the moving path of the clamping plate 3 more stable, and then the clamping plate 3 can drive the contraction spring 5 to produce displacement work when the highway bridge contracts.

[0037] Going further:

[0038] In an optional embodiment, the contraction spring 5 is located at the midpoint of the clamping plate 3 .

[0039] In this embodiment: the contraction spring 5 arranged at the midpoint of the card plate 3 can be used to buffer when the card plate 3 is displaced, thereby allowing enough space for the expansion and contraction of the bridge.

[0040] Going further:

[0041] In an optional embodiment, the B docking block 6 and the A docking block 2 are equidistantly arranged on both sides of the beam body 1 .

[0042] In this embodiment: the A docking blocks 2 and the B docking blocks 6 which are equidistantly arranged can have a sufficient contact surface when the beam body 1 is spliced, which can increase the tightness during splicing and ensure the stability of the highway bridge.

[0043] Going further:

[0044] In an optional embodiment, the clamping blocks 7 are symmetrically arranged on both sides of the B docking block 6, and the shape of the clamping blocks 7 is a right-angle ladder column.

[0045] In this embodiment: the symmetrically arranged clamping blocks 7 can simultaneously contact the clamping plate 3 when the two sides are spliced, and the contraction of the positioning spring 8 can enable it to engage with the clamping plate 3, thereby making the splicing work tighter.

[0046] The working principle and use process of the utility model are as follows: when the beam bodies 1 need to be butt-jointed, the A butt-jointed block 2 on one side of the beam body 1 is oriented toward the direction of the B butt-jointed block 6 of the other beam body 1, and the two beam bodies 1 are butt-jointed. At this time, the A butt-jointed block 2 and the B butt-jointed block 6 are staggeredly connected, and the card plate 3 provided on the surface of the A butt-jointed block 2 is connected to the card block 7, and the connection between the card plate 3 and the card block 7 promotes the card block 7 and the B butt-jointed block 6 to slide, thereby compressing the positioning spring 8 inside the B butt-jointed block 6. As the A butt-jointed block 2 and the B butt-jointed block 6 move further, , the card plate 3 will pass the position of the block 7, and the block 7 will reset under the rebound of the positioning spring 8 and block the card plate 3 after the card plate 3 is no longer blocked. At this time, the docking work between the two beams 1 is completed. When the temperature changes and causes the bridge to shrink, tension will be generated between the beams 1 and 1, and stress will be generated between the card plate 3 and the block 7 that remain in the engaged state, pulling the card plate 3 to slide in the slide groove 4 opened inside the A docking block 2. At this time, the card plate 3 and the A docking block 2 will compress the contraction spring 5 and buffer the space between the beams 1 and 1.

[0047] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
