[0002] The prefabricated steel bridge is a common temporary bridge facility, which is an upper and lower bearing bridge with single-pin connection truss units as the main girder of the bridge span structure. In the installation process of the prefabricated steel bridge in the prior art, it is often The installation of the bridge deck is realized by installing the grid bridge deck between the two connected beams. Then, due to the different installation positions and structural strength requirements, the installation grid bridge deck used for the bridge deck in the prior art is often based on In the actual situation, panels with different parameters are selected. At the same time, due to installation errors and other reasons during installation, the support strength and support position of the bridge deck will be unstable, which will affect the safety and service life of the entire bridge.

Embodiment Construction
[0037] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0038] Such as Figure 2-4 As shown, it is a truss steel bridge provided by the present invention. The truss steel bridge includes long beams 1 and short beams 2 that are parallel to each other and arranged at intervals. Several groups of truss structures 3 connected to each other are provided with reinforcing chord beams 4 at the top of each truss structure 3, and diagonal brace assemblies 5 are also provided between the left and right ends of the long beam 1 and the truss structures 3. A grid bridge deck is laid on the top of the adjacent two long beams 1 and short beams 2;
[0039] The long beam 1 includes a long beam body 1-1, the long beam connecting pl...
