Problems solved by technology

[0002] The traditional steel trestle generally adopts the form of top-supporting structure. Since the steel pipe piles of this type are welded in parallel to maintain the horizontal integrity, quality control and on-site operation are more difficult. The fabricated steel trestle, in In the assembly process, steel pipe piles are used to set parallel joints at the corresponding positions to ensure the integrity of the structure, and the technical optimization has been completed in terms of structure, but the firmness is poorer than the traditional welding method, and the firmness needs to be further improved

Embodiment 1

[0019] see Figure 1-3 , an assembled steel trestle bridge supported by H-shaped steel, including a plurality of H-shaped support rods 1 and bridge plates 5 fixed to the foundation, the top outer wall of the H-shaped support rods 1 is covered with auxiliary supports 2, and the auxiliary supports 2 When it is a steel member with a hollow structure, a sealing partition 21 is welded on the inner wall of the auxiliary support 2, and the sealing partition 21 divides the inner cavity of the auxiliary support 2 into two spaces, and the two sides of the upper surface of the auxiliary support 2 A vertical upward limiting plate 22 is welded symmetrically on the side, and the sealing partition 21 is closer to the limiting plate 22, and the surface of the limiting plate 22 is fixed with an H-shaped block 221 stuck in the auxiliary support 2, so that the H The block 221 is placed inside and its upper surface can be flush with the surface of the auxiliary support 2. The end surface of the H...

Embodiment 2

[0021] see Figure 4-5 , between a plurality of bridge plates 5, insert the through holes through the columns to improve the fixity of the bridge plates 5 on the H-shaped frame plate 4, and at the same time position the bridge plates 5 to facilitate the embedding of the dovetail tenon 9, while the adjacent bridge plates The hole positions of the dovetail semi-blind holes 53 on the side of the plate 5 are aligned. After the adjacent bridge plates 5 are put together, after the dovetail 9 is placed in the dovetail semi-blind holes 53, the bridge plates are further fixed. The firmness between 5.

[0022] To sum up: the assembled steel trestle bridge supported by H-shaped steel, the limit plate 22 blocks the two sides of the H-shaped beam 3 to prevent the H-shaped beam 3 from falling off, and improves the stability. The accumulated water is drained away, and at the same time, the water will not flow into the inner cavity of the bridge plate 5, so as to avoid oxidation after a long...

Abstract

The invention discloses an assembly-type steel trestle supported by H-shaped steel. The steel trestle includes multiple H-shaped supporting rods and bridge plates both of which are fixed with foundation, H-shaped blocks clamped into auxiliary supporting pieces are fixed to the surfaces of limiting plates, an H-shaped cross girder is in contact connection with the end face of the corresponding H-shaped block between every two adjacent limiting plates, first columns and second columns are embedded in first through holes and second through holes respectively, and dovetail dowels are embedded in dovetail dowel half-blind holes. According to the assembly-type steel trestle supported by the H-shaped steel, the limiting plates can clamp the two sides of the H-shaped cross girders to prevent the H-shaped cross girders from detaching, the stability is improved, and accumulated water on the bridge plates can be drained out through water guiding pipes and cannot flow into inner cavities of the bridge plates at the same time, so that the situation that oxidation happens after long-time use and then the service life is influenced is avoided. The first columns and the second columns can be accurately inserted into the first through holes and the second through holes respectively, and after every two adjacent bridge plates are placed together and the dovetail dowels are put into the dovetaildowel half-blind holes, the firmness between every two adjacent fixed bridge plates is further improved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to an assembled steel trestle bridge supported by H-shaped steel. Background technique [0002] The traditional steel trestle generally adopts the form of top-supporting structure. Since the steel pipe piles of this type are welded in parallel to maintain the horizontal integrity, quality control and on-site operation are more difficult. The fabricated steel trestle, in In the assembly process, steel pipe piles are used to set parallel joints at the corresponding positions, which ensures the integrity of the structure and completes the technical optimization of the structure, but the firmness is poorer than the traditional welding method, and the firmness needs to be further improved. Contents of the invention [0003] The object of the present invention is to provide an assembled steel trestle bridge supported by H-shaped steel, which has the advantages of firmness between b...
