Description

Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to an assembled bridge. Background Art

[0002] Prefabricated bridges are different from traditional on-site construction methods such as steel bar binding and concrete pouring. For prefabricated bridges, part or all of the components of the bridge's substructure and superstructure are processed and formed in a prefabricated component factory, then transported to the construction site for hoisting and splicing into the main body of the bridge. The various components of the bridge are mechanically connected through pre-embedded holes, pre-embedded steel bars, and connecting devices processed during the prefabrication process. Grouting is performed using grouting sleeves in the components so that the concrete fully fills the gaps between the components, achieving overall strengthening.

[0003] However, it still has some disadvantages, such as: it is too heavy, inconvenient to transport, and on-site installation may require the deployment of a larger crane for installation operations. In some narrow rural road areas, it is very likely that the installation will not be possible, and the heavy prefabricated bridge cannot be installed better.

[0004] In order to solve the above problems, this application proposes an assembled bridge. Utility Model Content

The lightweight assembled bridge body includes a bridge body, a connecting body, and a pier device. The connecting body is detachably installed on the front and rear sides of the bridge body. A pier device is arranged below the bridge body and the connecting body, and there are four groups of pier devices. The lightweight assembled bridge body is convenient for reducing its own weight without losing the load-bearing performance of the bridge. The lifting and lowering connection can also more conveniently use a crane to lift and install the lightweight assembled bridge body without wear due to friction between the crane and the crane.

[0007] Preferably, a weight-reducing metal mesh is provided inside the bridge body, two sets of lifting and lowering connections are provided below the bridge body, and multiple sets of railing installation openings are provided on both sides above the bridge body. The weight-reducing metal mesh is used to reduce the use of materials by hollowing out part of the space, thereby reducing weight without losing the stability of the material, and is more suitable for use as a temporary bridge.

[0008] Preferably, a plurality of first grouting holes are provided above the bridge body, a connecting port is installed on the front of the connecting body, the detachable railing is detachable on the left and right sides above the bridge body, the detachable railing includes a handrail column and a railing column, the railing column is detachable inside the railing installation port, the handrail column is installed above the railing column, and the detachable railing is convenient for directly inserting the detachable railing for installation after the lightweight assembly bridge body is installed, which is simpler and more convenient.

[0009] Preferably, bridge body steel bars are provided on the front and rear sides of the bridge body, and there are multiple groups of bridge body steel bars. First half grooves are provided on the front and rear sides of the bridge body, and there are two groups of first half grooves on each side. The bridge body steel bars can be removed inside the link port. Two groups of second half grooves are provided under the link body, and the first half grooves are communicated with the second half grooves. The split installation of the link body and the bridge body can facilitate the disassembly and transportation by the staff.

[0010] Preferably, a limit block is installed above the pier device, a second grouting hole is provided inside the limit block, the pier device is detachable above the pier base, pier steel bars are installed above the inside of the pier base, and the pier steel bars are detachable below the pier device. When installing the lightweight assembled bridge body, the link body is first connected to the bridge body, and the bridge body steel bars are inserted into the link port. At this time, the first half groove is merged with the second half groove, and the limit blocks above the four groups of pier devices are correspondingly inserted into the first half groove and the second half groove. Finally, mud is poured through the first grouting hole, and poured into the pier device through the second grouting hole to finally complete the fixation.

[0011] Preferably, the lifting and lowering connection includes a handle and a load-bearing beam, the load-bearing beam is installed below the bridge body, the load-bearing beam is installed below the link body, and the handle is installed on the left and right sides of the load-bearing beam. The lifting and lowering connection can more conveniently use a crane arm to lift and install the lightweight assembled bridge body without wear due to friction between the crane arm.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides a lightweight assembled bridge body, which is convenient for reducing its own weight without losing the load-bearing performance of the bridge. The lightweight assembled bridge body can also be more conveniently lifted and installed using a crane arm through the lifting and lowering connection, and will not be worn due to friction between the crane arm, so it has a good prospect of use.
