Product introduction

In the 21st century, with the rapid economic development, as the most widely used assembled load-bearing member in China, the economical and convenient movable steel bridge has been widely used in engineering construction, especially in the construction of convenience bridge. This kind of steel bridge is mainly assembled by beret sheet, which has the characteristics of simple structure, convenient transportation, quick erection, large load, good interchangeability and strong adaptability.

The main characteristic of the movable steel bridge is that the parts are light and light. The pins or bolts are used to connect the parts, so it is easy to assemble and disassemble. Only simple tools and manpower are needed to quickly complete the construction of the bridge.

First check the number of components in accordance with the design is complete, check whether the components, especially the pin and other important stress components are damaged, if necessary, should carry out flaw detection inspection pin. The bridge truss is welded by the vertical rod and the inclined rod. One end of the upper and lower chord rods is the negative head, and the other end is the positive head. There are pin holes on the head of Yin and Yang. When the two trusses are connected, insert the male head of one section into the female head of the other section, align with the pin hole, insert the pin, and finally insert the safety bolt.

There are many round hole steel plates welded on the chord. When the truss is used on the upper part of the bridge, the middle two holes are used. When the trusses are used as piers, a pair of holes at the ends are used to strengthen the upper and lower trusses. The round holes on the steel plates at both ends of the lower chord rod and the long round holes on the steel webs of the chord rod channel are called wind holes, which are used to connect the anti-wind tie rod.

Product application

Movable steel bridge can be used for highway bridge, gantry crane, guide beam, bridge erecting machine, hanging basket, etc. The main component is Beret truss, which is made of assembled highway bridge beam steel members assembled door type, but the span and column height are adjustable to adapt to different workplaces. It is widely used in highway, railway, municipal, construction, water conservancy and other construction projects. Bridge construction, assembly line sewing, such as lifting and dismantling assembly line, is used in the site construction of bridge pier and girder.
