Embodiment 1

[0041] refer to Figure 1-7 , a bridge steel structure, including a bridge deck, the bottom of the bridge deck is fixedly installed with a fixed plate, the side of the fixed plate away from the bridge deck is provided with a bridge deck base, and the bridge deck base is connected to the fixed plate with a shock-absorbing The shock-absorbing structure is evenly distributed between the bridge deck base and the fixed plate. The side of the bridge deck base away from the fixed plate is fixedly installed with the main pier. The main pier is symmetrical with the central axis of the bridge deck base as the axis of symmetry. distribution, the two main piers are fixedly connected with a main arc-shaped tunnel, and the side of the main pier away from the main arc-shaped tunnel is equipped with auxiliary piers, and the auxiliary piers and the main piers are fixedly connected with an auxiliary arc-shaped tunnel, and the two auxiliary piers are fixedly connected There is a support frame, w...

Embodiment 2

[0062] On the basis of embodiment 1, the following adjustments are made to the specific steps before welding and the specific welding steps:

[0063] A welding method for a bridge steel structure, the specific steps before welding are as follows:

[0064] S1. Read the process documents carefully before assembly, and the direction of the steel plate, the position and size of the weld must be seen clearly. or arc receiving plate;

[0065] S2, steel plate is assembled:

[0066] S3. During the assembly process, the steel plate is welded and positioned, and the basic electrode with the electrode grade of 507 is used. The electrode should be placed in the insulation tube and used as it is taken out. The DC reverse connection method is used for welding;

[0067] S4. For tack welding during assembly, the welding length should be more than 50mm, the spacing should be less than 400mm, and the filling section should not exceed half of the weld cross section, and when cracks occur in ta...

Abstract

The invention discloses a bridge steel structure and a welding method thereof. The bridge steel structure comprises a bridge deck slab; a fixing plate is fixedly installed at the bottom end of the bridge deck slab; a bridge deck base is arranged on the side, away from the bridge deck slab, of the fixing plate; and damping structures are connected to the bridge deck base and the fixing plate and evenly distributed between the bridge deck base and the fixing plate; main piers are fixedly installed on the side, away from the fixing plate, of the bridge deck base and are symmetrically distributedwith the central axis of the bridge deck base as the symmetry axis. The bridge steel structure is novel in structure, simple in structure, good in damping effect, small in jolt and noise, high in stability, high in welding accuracy, high in adjustability and good in welding effect.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a bridge steel structure and a welding method thereof. Background technique [0002] Welding operation is one of the important links in the construction of steel structure bridges. The quality of welding also directly affects the construction quality of steel structure bridges. In the actual construction process, it is also required to follow the actual construction conditions and construction environment of steel structures Select the appropriate welding technology for construction, and after the welding work is completed, the welding quality should be carefully inspected by special quality management personnel to ensure that the welding quality meets the construction requirements of steel structure bridges. [0003] The bridge steel structure and its welding method currently used in the market still have deficiencies during use, poor stability, easy to produce bumps and noise, easy to da...
