Description

Technical Field

[0001] The utility model relates to the technical field of bridge pipeline laying, in particular to an assembled bridge frame used for laying pipelines along a bridge. Background Art

[0002] For pedestrian trails built within ecologically sensitive lakeside areas, bridge structures are often used to ensure connectivity when crossing rivers and wetlands to minimize the ecological impact of roadbed fill. To prevent damage to the surrounding environment caused by activities during construction, the principle of low-impact construction is adopted, minimizing construction cycles. Furthermore, to avoid disrupting the existing landscape, bridges are typically designed to blend into the environment. Therefore, these bridges typically utilize prefabricated steel structures, with bolted connections typically used on-site. Furthermore, while meeting relevant river flood control requirements, the bridges are kept low above the ground.

[0003] Since the walking trail requires related supporting ancillary lighting, monitoring, water supply, etc., pipelines need to be installed along the route. For the roadbed section, the pipelines can be excavated and laid on the roadside. However, for the bridge section, which is mostly a wetland water system environment, the cost of excavation and laying in such an environment is high, and the existing ecological environment is also severely damaged during the construction process. In addition, the waterproofing of the pipeline is extremely difficult to deal with. Therefore, in the bridge section, the method of laying pipelines along the bridge is often adopted. The currently commonly used method of laying pipelines along the bridge is to set up a bridge frame at the bottom of the beam and then hang the pipeline on the bridge frame. Conventional methods of connecting the bridge frame to the bottom of the beam include bolt connection, welding, hanging connection, etc.

[0004] Common bolting or welding methods are unsuitable for installing pipeline supports alongside the bridge in this environment. Bolts can only be connected by pre-welding or on-site bolt hole drilling. If bolts are welded to the steel box girder, the weld can only be placed around the nut, limiting the connection length. This means individual bolts cannot withstand significant loads, necessitating closer bolt spacing and, consequently, bracket spacing. This increases the number of construction steps and reduces installation efficiency in environments with limited underbridge clearance. On-site bolt hole drilling compromises the seal in closed boxes and prevents bolt insertion and tightening. While it is possible in open boxes, on-site drilling is extremely difficult for the thick plates of the superstructure, requiring drilling from the bottom up, further complicating the construction process. If on-site welding is used, the finished supports can only be connected to the box girder via overhead welding. Overhead welding is challenging due to limited space and difficulty, and quality assurance is difficult. Furthermore, in some wooded environments, on-site welding poses a fire hazard, necessitating additional protective measures. Utility Model Content

[0024] Specifically, when installing the water supply pipeline bridge 1, first use a welding gun to weld the first connecting plate 11 to the bottom end of the bridge 3, and then use a crane to lift the welded parts of the first support plate 13, the second support plate 14 and the water supply bridge bottom plate 15, so that the first through hole 12a is aligned with the second through hole 13a, wherein the first support plate 13 is located above the second connecting plate 12, insert the bolts into the first through hole 12a and the second through hole 13a, and finally tighten the bolts with nuts.

[0025] Furthermore, the upper end of the water supply bridge bottom plate 15 is fixedly connected to a water pipe limiting base 16, the upper end surface of the water pipe limiting base 16 is arc-shaped, and the upper section of the water pipe limiting base 16 is tightly attached to the outer wall of the laid water pipe 17 to achieve left and right direction limitation of the water pipe.

[0026] Furthermore, the power supply pipeline bridge 2 includes a power supply support plate 21 and a power supply bridge bottom plate 22. The power supply support plate 21 is welded and fixed on both sides of the power supply bridge bottom plate 22.
