Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and particularly relates to a containerized combined structure and method for a bridge. Background Art

[0002] The prefabricated bridge construction technology refers to the technology of prefabricating or processing relevant components of a bridge in a factory first, and then transporting the components to a designated construction site for on-site assembly of the bridge; compared with the traditional cast-in-place reinforced concrete construction, the types and sizes of prefabricated bridge components tend to be standardized, which is conducive to large-scale industrial manufacturing. The production process of components can be centrally quality-controlled in the factory or prefabrication yard. For example, advanced semi-automatic or automatic construction technologies can be uniformly adopted, which improves production efficiency, reduces project cost, and at the same time, the quality of components is easy to guarantee; during on-site assembly, mechanical construction is mainly used, and the input of manpower is relatively small, the on-site construction speed is fast, and theoretically it can be opened to traffic immediately after assembly, greatly shortening the construction period and saving project cost.

[0003] Of course, there are also some deficiencies in prefabricated bridges. For example, each component needs to be transported from the factory to the construction site for assembly. There are many relevant components of the bridge. Some components are heavy and some are long, so different requirements are imposed on the transport vehicles for each component. Some components may even need to be carried by specially customized transport vehicles, which significantly increases the transportation cost of beam bridges; in addition, in the existing transportation methods of prefabricated bridge components, when loading each component onto the vehicle, generally only a simple distribution is made according to the volume and weight of each component, and it cannot ensure the completeness of the components on a single transport vehicle, that is, the types and quantities of the corresponding components on the transport vehicle cannot ensure that a complete bridge structure can be formed after mutual assembly.

[0004] In view of this, the present application aims to provide a containerized combined structure and method for a bridge, which can stack all the components of a section of the bridge into a container-like structure, so as to be placed in the same transport vehicle for easy transportation. At the same time, since the necessary components for forming a section of the bridge structure are included in the same vehicle, as long as one transport vehicle arrives at the construction site, assembly construction can be started, and the components on the vehicle can be assembled into a complete bridge structure, without waiting for multiple transport vehicles to arrive to ensure the completeness of the bridge components before starting the assembly work. Summary of the Invention

[0005] The object of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a containerized combined structure and method for a bridge, which can stack all the components of a section of the bridge to form a container-like structure for convenient transportation.

[0006] The technical solution of the present invention is: a containerized combined structure for a bridge, including a plurality of bridge decks, a plurality of longitudinal beams, a plurality of cross beams, and at least one bridge pier and a main beam. On one side of the combined structure, the bridge deck, the longitudinal beam, and a part of the cross beam are arranged in sequence from bottom to top, and a part of the cross beam is arranged staggeredly with the longitudinal beam; on the other side of the combined structure, the main beam, the bridge pier, and another part of the cross beam are arranged in sequence from bottom to top.

[0007] Further, the bridge deck and the main beam are placed vertically, and the longitudinal beam and the bridge pier are placed horizontally.

[0008] Further, the longitudinal beam, the main beam, and the cross beam all adopt a truss structure.

[0009] Further, the longitudinal beam includes an upper chord, a lower chord, and connecting rods arranged between the upper chord and the lower chord; there are multiple connecting rods, and the lengths of the connecting rods are different, so that the longitudinal beam itself can form a truss structure, which can reduce the weight while ensuring the strength; the structure of the cross beam is similar to that of the longitudinal beam.

[0010] Further, at least one end of the upper chord or the lower chord of the longitudinal beam is provided with a flange for facilitating bolt connection.

[0011] Further, the bridge deck is a steel structure plate.

[0012] Further, the bridge pier is cylindrical, and a threaded hole is provided at the top of the bridge pier for facilitating bolt connection with the main beam.

[0013] Further, the sum of the thicknesses of all the bridge decks and the main beam is equivalent to the sum of the widths of one longitudinal beam and one cross beam, so that the combined structure can generally maintain a constant width.

[0014] The present invention also provides a specific combination method for the containerized combined structure of the above bridge: First, arrange the bridge deck and the main beam; then arrange the bridge pier on the main beam, and arrange the longitudinal beam and the cross beam on the bridge deck; finally, arrange the remaining cross beams on the bridge pier.

[0015] Further, when arranging the bridge deck and the main beam, hoist the bridge deck and the main beam onto the transport vehicle in sequence, and keep the bridge deck and the main beam placed horizontally vertically.

[0016] Further, the longitudinal beam and the cross beam on the bridge deck are arranged staggeredly, so that the stacking height of the longitudinal beam and the cross beam can be reduced; the reason is that in this application, the thickness of the longitudinal beam is thick at both sides and thin in the middle, and the width of the cross beam is smaller than that of the longitudinal beam. Therefore, placing a cross beam between two stacked longitudinal beams is more conducive to making full use of space.

[0017] Advantages of the present invention compared with the prior art: In the bridge containerized combined structure of the present invention, all components of a section of the bridge are stacked in a container shape according to a certain combination method, and the size of the combined structure is adapted to the standard size of the existing container, thus facilitating transportation and saving the transportation cost of the prefabricated bridge. At the same time, since a vehicle contains the necessary components for forming a section of the bridge structure, as long as one transport vehicle arrives at the construction site, the assembly construction can be started in a timely manner, and the components on the vehicle can be used to assemble a complete bridge structure. Different from the assembly methods of some bridges in the prior art, it is necessary to wait for multiple transport vehicles to arrive to ensure the completeness of the bridge components and then the assembly work can be started. It can be seen that the combined structure in the present invention is not only convenient for transportation, but also can effectively save the time for waiting for relevant components and improve the bridge construction efficiency.

[0021] The following will further describe the present invention in detail with reference to specific embodiments. The methods or functional components not specifically described in the embodiments are all prior arts.

[0022] Embodiment 1

[0023] As Figure 1-2 shown, this embodiment is a containerized combined structure of a bridge, including 1 bridge pier 5, 1 main beam 4, 8 bridge decks 1, 4 longitudinal beams 2 and several cross beams 3. On one side of the combined structure, the bridge deck 1, the longitudinal beam 2 and some of the cross beams 3 are arranged in sequence from bottom to top, and these cross beams 3 are arranged alternately with the longitudinal beam 2; on the other side of the combined structure, the main beam 4, the bridge pier 5 and the remaining cross beams 3 are arranged in sequence from bottom to top. The bridge deck 1 and the main beam 4 are both placed horizontally in the transverse direction, that is, the length direction of the bridge deck 1 and the main beam 4 is horizontal, the width direction is vertical, and the thickness direction is also horizontal. The longitudinal beam 2 and the bridge pier 5 are both placed horizontally.

[0024] In this embodiment, the main beam 4, the longitudinal beam 2 and the cross beam 3 of the bridge all adopt a truss structure. For example, the longitudinal beam 2 includes an upper chord, a lower chord and connecting rods arranged between the upper chord and the lower chord; there are multiple connecting rods, and the lengths of the connecting rods are different, so that the longitudinal beam 2 itself can form a truss structure, which can reduce the weight while ensuring the strength; the structure of the cross beam 3 is similar to that of the longitudinal beam 2.

[0025] In this embodiment, flanges are provided at at least one end of the upper chord or the lower chord of the longitudinal beam 2, facilitating bolt connection. The bridge deck 1 is a steel structure plate, and the bridge pier 5 is cylindrical. Threaded holes are provided at the top of the bridge pier 5, facilitating bolt connection with the main beam 4.

[0026] In this embodiment, the sum of the thicknesses of all the bridge decks 1 and the main beams 4 is equivalent to the sum of the widths of one longitudinal beam 2 and one cross beam 3, enabling the composite structure to generally maintain a constant width.

[0027] The combination method of the bridge container-type composite structure in this embodiment includes the following steps:

[0028] First, arrange the bridge deck and the main beam 4. Lift and install the main beam 4 and multiple bridge decks into the carriage of the transport vehicle 6. The bridge decks and the main beam 4 are both placed horizontally in a vertical position, and are arranged in sequence from left to right or from right to left, such that the bridge decks and the main beam 4 fill the lower space of the carriage. Then, arrange the bridge piers 5, the longitudinal beams 2, and some of the cross beams 3 above the bridge decks and the main beam 4. Among them, the bridge piers 5 are placed above the main beam 4, and the longitudinal beams 2 and some of the cross beams 3 are placed above the bridge decks. The longitudinal beams 2 and the cross beams 3 are placed horizontally in an alternating manner. For example, first place a longitudinal beam 2 on the bridge deck, then place a cross beam 3 on this longitudinal beam 2, and then place another longitudinal beam 2 on the cross beam 3, and so on. Until all the longitudinal beams 2 are placed, and the topmost is a cross beam 3. Finally, place the remaining cross beams 3 on the bridge piers 5, and all the components of a section of the bridge can form a cuboid shape.

[0029] Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is that there is another cross beam 3 arranged vertically outside the alternating structure of the longitudinal beam 2 and the cross beam 3. This cross beam 3 can be fixed to the carriage of the transport vehicle, thereby preventing the longitudinal beam 2 and the cross beam 3 in the alternating structure from slipping sideways. Improving the stability of the entire composite structure.

[0031] The above are only some embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have combinations and variations of the foregoing various technical features. Without departing from the spirit and scope of the present invention, improvements, variations, equivalent substitutions made by those skilled in the art, or the use of the structure or method of the present invention in other fields to achieve the same effect all fall within the protection scope included in the present invention.
