Technical Field

[0001] The present invention belongs to the technical field of assembled steel structure trestle, and in particular relates to an integrated insulation floor system of an assembled modular steel structure trestle. Background Art

[0002] A trestle is an overhead bridge structure. In recent years, with the continuous improvement of enterprise production capacity, the increasing demand for output and raw materials, material transport trestles have gradually developed into larger ones. The trestles have gradually evolved through different structural forms before developing into the current steel structure trestles.

[0003] The construction of floor module systems for traditional steel structure trestle structures generally uses reinforced truss floor decks and post-poured concrete. There are many wet operations on site, low construction efficiency, and the concrete needs to be cured. In addition, the thermal insulation performance of traditional floor module systems is poor, and insulation measures must be taken in high-altitude and cold areas. Summary of the Invention

[0004] In order to solve the above problems, the present invention adopts the following technical solutions:

[0005] A thermally-insulated integrated floor system for an assembled modular steel structure trestle comprises a floor module and a square frame consisting of two lower longitudinal beams and two end transverse beams, wherein the two lower longitudinal beams are arranged relative to each other, and the two end transverse beams are arranged relative to each other. The floor module is composed of a plurality of precast concrete trough plates arranged in sequence, the bottoms of the precast concrete trough plates being provided with thermal insulation material, and the plurality of precast concrete trough plates being arranged in sequence within the square frame along the length direction of the end transverse beams.

[0006] Furthermore, the precast concrete trough plate is a U-shaped structure, and the thermal insulation material is arranged in the groove of the precast concrete trough plate.

[0007] Furthermore, a cavity is provided in the precast concrete trough plate, and reserved grouting holes are provided at both ends of a side of the precast concrete trough plate away from the opening.

[0008] Furthermore, there are four reserved grouting holes, which are respectively located at the four corners of the precast concrete trough plate.

[0009] Furthermore, a bolt group consisting of a plurality of bolts is provided on one side of the end transverse beam.

[0010] Furthermore, two groups of bolt groups are provided, and the two groups of bolt groups are arranged oppositely on the end transverse beam.

[0011] Furthermore, the bolt group is provided in one group.

[0012] Furthermore, the plurality of studs are arranged corresponding to the reserved grouting holes of the plurality of precast concrete trough plates, and are distributed on the end transverse beam along the length direction of the end transverse beam.

[0013] Furthermore, the end transverse beam is a structure selected from the group consisting of H-shaped steel, channel steel, angle steel and rectangular steel pipe.

[0014] Beneficial effects:

[0015] Compared with the existing traditional floor system construction method, the present invention is easy and efficient to install, with less on-site wet work; through high-strength grouting materials and post-poured concrete, the floor module has good integrity and high structural rigidity; the insulation material is built into the bottom of the grooved plate, which greatly improves the thermal insulation performance of the trestle structure.
