The durability is greatly improved as a reference due to the adoption of high-quality materials and elimination of cracks caused by live load, so that the construction site joint of the concrete structure is safe and reliable. Because of the pre-stressing process, the construction method is only suitable for various construction methods without supports for erecting steel bridges, and can be used for the concrete bridge at present, so that the construction cost is obviously reduced, and the noise of the bridge is low.
However, in port construction, the metal structure of the traditional steel trestle has simple functions, as shown in fig. 1, and cannot meet the safety and functionality requirements of personnel, vehicles and dangerous chemical delivery. Hazardous chemical pipelines are generally arranged at positions 1 on two sides of a steel trestle, so that the hazardous chemical pipelines cannot resist the high-salinity high-humidity severe atmospheric corrosion environment on the sea. The design of the box body beam is complex due to the passing requirements of personnel and vehicles, the personnel overhaul and vehicle channel 2 is arranged in the middle, and the H-shaped steel beam 3 is arranged in a pull-up mode, so that the construction cost is high, the installation is difficult, and the method is not economical.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned defect that exists among the prior art, the utility model aims at providing a steel trestle metal construction suitable for harbour adopts high strength multifunctional design, can satisfy the security requirement that dangerous chemicals carried.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a steel trestle metal structure suitable for harbor comprises a main beam component, an automobile channel platform connected with one side of the main beam component, an overhaul channel platform connected with the other side of the main beam component, and a dangerous chemical pipeline installation channel;
the main beam member is a rectangular body, the side plates on the two side surfaces of the main beam member are box beams, and the top surface of the main beam member is of an H-shaped steel beam and diagonal draw bar combined structure;
the H-shaped steel beam and diagonal draw bar combined structure comprises a plurality of H-shaped steel beams, each H-shaped steel beam is connected between the box body beams on two sides at equal intervals, and a group of diagonal draw bars is connected between every two adjacent H-shaped steel beams;
the group of diagonal draw bars is formed by connecting two diagonal draw bars in an X shape between two adjacent H-shaped steel beams;
the bottom surface and the top surface of the main beam member are arranged the same.
The automobile passage platform is composed of a plurality of prefabricated parts.
The prefab is latticed that constitutes by a plurality of horizontal girder steels and a plurality of perpendicular girder steels, links to each other through agreeing with public female interface fast between two adjacent prefabs.
The box body beam, the H-shaped steel beam and the diagonal draw bar are all in welded connection.
In the technical scheme, the utility model provides a steel trestle metal construction suitable for harbour adopts the multi-functional design of high strength, can satisfy the security requirement that dangerous chemical carried. The metal structure formed by welding the box body beam, the H-shaped steel beam and the diagonal draw bars can bear large dynamic load, and the automobile channel platform and the overhaul channel platform respectively bear personnel, vehicles and dangerous chemical pipelines on the box body beam and keep the three at a certain safe distance.
