[0003] When installing a prefabricated steel bridge, it is necessary to install the pedals on the steel bridge. However, when installing the current pedals, the pedals are installed one by one through screws. There are many screws to be fixed, and the installation is very cumbersome and single. The limiting effect of the screw is not enough, once it is loosened, it will cause the pedal to tilt and shift

Embodiment Construction
[0027] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0028] Such as Figure 1-Figure 5 As shown, an assembled steel bridge according to the present invention includes a supporting mechanism 1, a first steel plate 2, a second steel plate 3, a pressing mechanism 4 and a reinforcing mechanism 5; the top surface of the supporting mechanism 1 is symmetrically arranged There are the first steel plate 2 and the second steel plate 3, the first steel plate 2 and the second steel plate 3 are used to form bridge pedals; the structure between the first steel plate 2 and the second steel plate 3 Similarly, the first steel plate 2 is buckled and connected to the second steel plate 3; the connection between the first steel plate 2 and the second steel plate 3 runs through the reinforcement mechanism 5, and the rei...

The invention relates to the technical field of steel bridges and specifically relates to an assembled steel bridge which comprises a disconnecting switch main body, a rotating mechanism, a handle, adriving mechanism, a connection mechanism and a disconnecting switch control mechanism. According to the assembled steel bridge disclosed by the invention, when a bridge walking pedal is assembled, aconnection head of a first steel plate can be arranged in a connection groove of a second steel plate, the connection head of a convex structure and the connection groove can against each other, and the steel plates are prevented from being horizontally separated and offsetting; the first steel plate and the second steel plate can be tightly pressed and limited by a hold-down mechanism, the steelplates are prevented from upwarping, and limiting in the horizontal and longitudinal directions is achieved; furthermore, the assembled steel bridge has the advantages of convenience in integral installation, less required screws and convenience in maintenance. By means of a lengthened rod and a supporting rod which are of square tube structures, the connection strength between the connection headand the connection groove is further improved, the connection head and the connection groove are prevented from staggering, and the flatness of the bridge pedal is ensured; furthermore, a lengtheningmechanism and a fixing mechanism can be rotated and folded up to bring convenience to storage, transportation and installation operation.
Description
technical field [0001] The invention relates to the technical field of steel bridges, in particular to an assembled steel bridge. Background technique [0002] Prefabricated steel bridges are usually suitable for emergency emergencies. Therefore, the bridge structure is required to be light, strong in mobility, convenient in transportation, fast in assembly, and strong in adaptability. It can be widely used in wartime repairs and peacetime flood control and disaster relief. Rapid construction of road bridges and temporary road bridges, as well as auxiliary equipment for road construction. [0003] When installing a prefabricated steel bridge, it is necessary to install the pedals on the steel bridge. However, when installing the current pedals, the pedals are installed one by one through screws. There are many screws to be fixed, and the installation is very cumbersome and single. The limiting effect of the screw is not enough, once it is loosened, it will cause the pedal t...
