Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] refer to figure 1 , is an underframe of a steel bridge frame disclosed by the present invention, comprising a support frame 2 supported on the lower end surface of a steel bridge frame 1 . In this embodiment, the support frame 2 and the steel bridge frame 1 are parallel to each other, and the top of the support frame 2 is fixed to the bottom of the steel bridge frame 1 .

[0042] refer to figure 2 , The support frame 2 includes a beam 21 and a vertical beam 22 . In this embodiment, there are several crossbeams 21, several crossbeams 21 are parallel to each other, several vertical beams 22 are provided, several vertical beams 22 are parallel to each other, and the crossbeams 21 and vertical beams 22 are perpendicular to each other and are all solid designs , the solid beams 21 and vertical beams 22 have a better supporting effect.

Abstract

The invention relates to an underframe of steel bridge frame. The underframe comprises a supporting frame supporting the lower end face of the steel bridge frame, and the supporting frame comprises aplurality of parallel cross beams and a plurality of parallel vertical beams. The cross beams and the vertical beams re perpendicular, and sliding grooves in sliding connection with the vertical beamsare formed in the cross beams. Supporting columns in butt joint with the ground are arranged at the intersections of the cross beams and the vertical beams. The underframe is stable in overall structure connection, and the large steel bridge frame can be supported; and due to the fact that the vertical beams penetrate through the cross beams, the connecting mode is simple, the cross beams and thevertical beams can be transported to the site to be constructed, and the transportation efficiency can be improved by transporting the cross beams and the vertical beams separately.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to an underframe of a steel bridge frame. Background technique [0002] With the continuous development of science and technology, transportation has become more and more convenient. Whether it is a train, a car, a bus or a subway, it is inseparable from the bridge. During the construction of the bridge, the main body of the bridge is mainly made of steel bridge frame and concrete poured on the steel beam bridge frame, so the steel beam bridge frame has made an inestimable contribution to the stability of the bridge. Therefore, ensuring the quality of the steel bridge frame is a very important key technology. [0003] The Chinese patent with the publication number CN104014970B discloses an adjustable steel structure field welding support frame, which is a welding support frame designed for the repeated use of steel structure members of different specifications on site, ...
