Abstract
The utility model discloses a steel structure bridge stand, which comprises a bridge body, bridge piers and bridge, wherein the bridge body is connected with the bridge by the bridge piers. The steel structure bridge stand of the utility model has simple structure and improved strength.
Description
Technical field
The utility model relates to a kind of crane span structure, particularly a kind of steel work crane span structure.
Background technology
In recent years, existing cement bridge or steel bridge are generally more than tens meters even hundred meters, play an increasingly important role in daily life, but its complex structure are installed inconvenient.And the intensity of existing bridge is bad, is washed away by flood easily.
The utility model content
Technical problem to be solved in the utility model provides a kind of steel work crane span structure, its simple in structure and raising intensity.
For solveing the technical problem, the utility model provides a kind of steel work crane span structure, it is characterized in that, it comprises pontic, bridge pier and bridge, and pontic and bridge are fixed together by bridge pier.
Preferably, described bridge is shaped as circular arc.
Positive progressive effect of the present utility model is: the utility model steel work crane span structure reduces manufacturing cost, and is simple in structure, the safety that can improve bridge.
Description of drawings
Fig. 1 is the structural representation of the utility model steel work crane span structure.
The specific embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model steel work crane span structure comprises pontic 1, bridge pier 2 and bridge 3, and pontic 1 is fixed together by bridge pier 2 with bridge 3.In the pontic 1 reinforcing rib 4 can be set across, also reinforcing rib 4 can be set across in the bridge pier 2, bridge 3 be shaped as circular arc.The utility model steel work crane span structure only needs four elements, can reduce manufacturing cost, and is simple in structure, the intensity and the safety that can improve bridge.
The material of pontic 1, bridge pier 2, bridge 3 and reinforcing rib 4 is a Q690E type high strength steel, and the yield strength of Q690E type high strength steel is more than or equal to 690Mpa, and tensile strength is 770-940Mpa.Because the intensity and the hardness of Q690E type high strength steel are higher, are using Q690E type high strength steel in super large floating crane and the shipbuilding on a large scale, and the not competent use in engineering of traditional low-alloy steel.This Q690E type high strength steel is made by applicant company, by opening bar, mill the limit, pre-bending, bending, moulding, joint close prewelding, interior weldering, outside weld, pipe end processing, aligning, finishing, repairing steps such as end and final detection and finish, have flawless and advantages of high strength, can improve the intensity and the safety of bridge.
Though more than described the specific embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
Claims (3)
1. a steel work crane span structure is characterized in that, it comprises pontic, bridge pier and bridge, and pontic and bridge are fixed together by bridge pier.
2. steel work crane span structure according to claim 1 is characterized in that, described bridge be shaped as circular arc.
3. steel work crane span structure according to claim 1 is characterized in that, in the pontic and in the bridge pier reinforcing rib is set across.
