Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to a high-strength steel structure bridge that can be quickly assembled. Background Art

[0002] Steel structure bridges, also known as steel structure bridges or steel bridges, use steel as their main load-bearing structure. The structure of this type of bridge consists of a main bridge along the longitudinal direction of the bridge, where the distance between the piers is called the span. The main materials used to manufacture steel structure bridges include steel plates, steel sections and high-strength steel. These materials have the characteristics of high strength and easy processing, making the components of steel structure bridges relatively light and convenient to transport and erect.

[0003] At present, when steel structure bridges are assembled, bridge decks are generally laid on the surface. However, the installation of bridge decks is now troublesome and requires the use of a large number of auxiliary equipment. In addition, there is a lack of connecting structure between the bridge decks after installation, resulting in the bridge decks being set up independently, affecting the overall stability and making it easy for one of the decks to warp up. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a high-strength steel structure bridge that can be quickly assembled and can be quickly installed, and can complete the connection between the bridge deck and the crossbeam while they are fixed, so as to solve the problems raised in the above-mentioned background technology.

[0006] As a preferred technical solution, a slot is provided on the outer side surface of the protruding end of the limiting plate, and an inserting portion is protruded on the inner side surface of the limiting plate, and the inserting portion is inserted into the corresponding slot.

[0007] As a preferred technical solution, a plurality of positioning grooves are provided on the bottom surface of the pressure plate, and a positioning plate is installed on the top surface of the bridge deck opposite to the positioning grooves. The pressure plates are slidably set on the positioning plates through the positioning grooves, and a first screw hole is provided on the positioning plates. A second screw hole is provided on the pressure plates opposite to the first screw hole, and bolts are threadedly connected in the first screw holes and the second screw holes opposite to each other.

[0008] As a preferred technical solution, the cross-sections of the positioning groove and the positioning plate are both arranged in a trapezoidal structure.

[0009] As a preferred technical solution, the clamping plates are all arranged in an "L"-shaped structure.

[0010] As a preferred technical solution, the limiting plate and the clamping plate are both made of steel.

[0011] The beneficial effects of the utility model are as follows: the utility model has a simple structure, the bridge deck can be placed on the crossbeam, the bridge deck can be laterally limited by the limit plate, and after the bridge decks are brought close together, the protruding end of the limit plate can be inserted into the notch of the adjacent limit plate, and when the clamping plate is clamped and fixed on the crossbeam, the inserting part on the clamping plate can be inserted into the slot of the adjacent limit plate, thereby directly completing the connection between the bridge deck and the crossbeam and the connection between adjacent bridge decks, thereby increasing the overall firmness of the bridge deck and the efficiency of installation.

That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model is a quickly assembled high-strength steel structure bridge, including a plurality of bridge panels 1 laid on a beam 2, limit plates 3 are installed at both ends of the bridge panels 1, the inner side surfaces of the limit plates 3 are set to abut against the outer beam 2, and one end of the limit plate 3 protrudes from the bridge panel 1, and a gap is formed between the other end and the bridge panel 1, and the protruding ends of adjacent limit plates 3 are inserted into the gaps, and clamping plates 4 are installed on the outer sides of the limit plates 3 through hinges, and the bottoms of the clamping plates 4 are hooked to the inner side of the beam 2, and pressure plates 5 are installed at both ends of the bridge panel 1 to press the clamping plates 4 downward and clamp them fixed on the beam 2.

[0021] In this embodiment, a slot 8 is provided on the outer side surface of the protruding end of the limiting plate 3 , and an inserting portion 10 is protruded on the inner side surface of the limiting plate 3 , and the inserting portion 10 is inserted into the corresponding slot 8 .

[0022] In this embodiment, a plurality of positioning grooves 6 are provided on the bottom surface of the pressure plate 5, and a positioning plate 7 is installed on the top surface of the bridge deck 1 opposite to the positioning grooves 6. The pressure plates 5 are slidably set on the positioning plates 7 through the positioning grooves 6, and a first screw hole is provided on the positioning plates 7. A second screw hole is provided on the pressure plate 5 opposite to the first screw hole, and bolts 9 are threadedly connected in the first screw hole and the second screw hole relative to each other.

[0023] In this embodiment, the cross-sections of the positioning groove 6 and the positioning plate 7 are both arranged in a trapezoidal structure, so that the pressing plate can only move back and forth along the positioning plate and exert a downward pressure on the clamping plate.

[0024] In this embodiment, the clamping plates 4 are all arranged in an "L"-shaped structure, so that the clamping plates can be rotatably hooked on the belly of the beam.

[0025] In this embodiment, the limiting plate 3 and the clamping plate 4 are both made of steel material, which increases the overall firmness and can be reused after disassembly.

[0026] During installation, the bridge deck is first placed on the crossbeam. After placement, the limit plates at both ends of the bridge deck can contact the outer crossbeam, thereby limiting the bridge deck to ensure lateral stability. After multiple bridge decks are placed together, the limit plates can be inserted into the gaps of adjacent limit plates until the limit plates are in contact with each other, and the bridge decks are also in contact with each other.

[0027] After the above is completed, the pressure plate is pushed outward, and the clamping plate can be squeezed by the pressure plate, so that the clamping plate rotates downward with the hinge as the center until it is clamped on the belly of the beam, so as to ensure the installation firmness between the bridge deck and the beam. In the process of the clamping plate approaching, the inserting part on the clamping plate can be inserted into the slot of the adjacent limit plate, and the adjacent bridge decks can be connected together through the connection between the inserting part and the slot, so as to increase the overall installation firmness and avoid the situation that one of the plates is prone to warping.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
