Steel Structure Prefab Truss Road Bridge/Railway Bridge

Product Description

　　The steel truss bridge is a structural system between beams and arches. It is a structure in which a bent upper beam structure and a pressure-bearing lower column are integrated together. Due to the rigid connection between the beam and the column, the beam is unloaded due to the flexural rigidity of the column. The entire system is a compression-bending structure as well as a thrust structure.

　　The structure composition of rigid truss beam bridge: Main girder, Bracing, Bridge deck system, Bridge floor.

  Form and mechanics

　　The individual pieces of a truss bridge intersect at truss joints, or panel points. The connected pieces forming the top and bottom of the truss are referred to respectively as the top and bottom chords. The sloping and vertical pieces connecting the chords are collectively referred to as the web of the truss.

　　The component parts of a truss bridge are stressed primarily in axial tension or compression. A single-span truss bridge is like a simply supported beam because it carries vertical loads by bending. Bending leads to compression, in the top chords (or horizontal members), tension in the bottom chords, and either tension or compression in the vertical and diagonal members, depending on their orientation.

　　Early trusses were built without precise knowledge of how the loads are carried by each part of the truss. The first engineer to analyze correctly the stresses in a truss was Squire Whipple, an American who designed hundreds of small truss bridges and published his theories in 1869. Understanding precisely how loads were carried led to a reduction in materials, which by then were shifting from wood and stone to iron and steel.

　　Our vehicular bridges have been installed in shopping centers, malls, hotels, residential developments, corporate facilities, golf courses, parks and recreational facilities. Customers include architects, engineers, contractors, developers, homeowners along with State and local governments. For those applications where site constraints are of a concern, regulatory requirements are interfering with site plans or an added architectural element is desired, our line of vehicular bridge products can meet your needs.


　　Steel Truss Bridge Installation

　　Steel truss bridges cannot be installed individually due to the large volume of components and the high height of the bridge body, and the cooperation of cranes is required. First install the bridge body of the lower chord as a support, then install the vertical rod to support the inclined rod, and finally install this small part of the upper chord. Each time a triangular structure is used as a unit, the overall bridge is gradually built.
