Problems solved by technology
However, the current fixed overpasses are often demolished due to the widening of urban development roads, resulting in huge waste; at the same time, those temporary crowds or special cross-road needs are often too late to build pedestrian cross-road passages

Embodiment Construction
[0012] The implementation of the low-span and high-span movable cross-road overpass does not require high technology and equipment. It is simple, convenient, material-saving, flexible, economical and efficient. In practice, the grouped beam 1 can be designed into discrete units of different volumes and lengths according to different traffic levels, so that the changing connection group can adapt to various road widths, and the section of the grouped beam 1 is the most economical and efficient Mouth-shaped or U-shaped, the bottom plane can be paved with various materials to form a passageway; the pin shaft link interface between the assembled beam 1 and the connection end of the climbing platform 4 and the shelving connection setting with the connection end of the central column 2 can be set according to safety and convenience. Choose a specific structure in principle. The central column 2 is composed of a bottom surface, a column and a beam. The bottom surface must have enough...

The invention provides a low span high assembly type movable road-span overbridge, which is a road-span passage overbridge combined by assembling an assembly beam, a center pillar and a climbing platform on site and can be detached to move and displace. The assembly beam is formed by connecting and assembling a plurality of separate square or U-shaped units; a passage way is arranged on the plane at the bottom of a beam frame; the center pillar is formed by assembling a bottom surface, a pillar and a cross beam; anti-impact piers are arranged on the front end and the back end of the center of a road; and the climbing platform is formed by assembling a top, a support and a stepped ladder or ramp separate parts. The low span high assembly type movable road-span overbridge has low cost and wide application, is convenient to move, and can realize transportation and propaganda functions only having the cost of a large road-span advertising board; the overbridge can be applied to downtown commercial streets, can be arranged close to venues and campus, can conveniently and temporally gather and disperse crowds, can be used as an engineering site road. The overbridge can be assembled in the morning and moved in the evening for application, can change span and give way, can be changed along with municipal arrangement of road widening, and ensures safety of passengers and traffics.
Description
technical field [0001] The invention belongs to the improvement of a road crossing overpass, in particular to a low-span and high-height assembled movable overpass. technical background [0002] Industrial civilization and the development of science and technology have made automobiles the main means of transportation in society, and the dense layout of criss-crossing roads has become an obvious feature of cities. In the prior art, in order to solve the traffic conflict between pedestrians crossing the road and vehicles passing, overpasses have long been used on busy roads. However, the existing fixed flyovers are often demolished due to the widening of urban development roads, resulting in huge waste; at the same time, those temporary crowds or special cross-road needs are often too late to build pedestrian cross-road passages. In order to save resources, reduce waste and hinder traffic safety, orderliness and efficiency, it is very necessary to improve the design of overp...
