Embodiment Construction
[0051] The present invention will be further described below in conjunction with the accompanying drawings and the summary of the invention.
[0052] Large-span modular composite emergency bridge suitable for manual assembly, see Figures 1 to 4 , including two string-tension truss girders 1 arranged in parallel and a bridge deck 2 arranged on the top of the string-tension truss girder 1; the string-tension truss girder 1 includes a truss girder body 3 and a string-tension reinforcement system 4 arranged below the truss girder body 3 .
[0053] The middle part of the truss girder body 3 is assembled by a set of middle bridge section standard modules 5, and the two ends are assembled by side bridge section transition modules 6 and side bridge sections 7;
[0054] Middle bridge section standard module 5, see Figures 5 to 6 , is a space truss with an equilateral triangular cross-section, including an upper chord 51, a lower left chord 52, a lower right chord 53, a pair of left...

The invention provides a large-span modularization composite emergency bridge suitable for being manually assembled. The bridge comprises two string truss girders arranged in parallel and bridge deckslabs arranged at the tops of the string truss girders; each string truss girder comprises a truss girder body and a string reinforcing system arranged below the truss girder body; and the middle portion of each truss girder body is assembled through a set of intermediate bridge section standard modules, and the two ends are assembled through edge bridge section transitional modules and edge bridge sections. The invention further provides an erection method of the large-span modularization composite emergency bridge suitable for being manually assembled. The large-span modularization compositeemergency bridge suitable for being manually assembled has the beneficial effects of being high in bearing capacity, high in modularization degree, small in mass and capable of being manually assembled and erected.
Description
technical field [0001] The invention belongs to the field of rapid construction and erection of lightweight emergency bridges, and in particular relates to a manually assembled large-span modular composite emergency bridge suitable for rapid construction and erection during emergency repairs and construction, and also relates to the emergency bridge by means of manual or light construction. Mechanical quick erection method. Background technique [0002] The existing large-span emergency bridge equipment is all steel structures. Although steel has the advantages of high strength, good plasticity and toughness, uniform force in all directions, and mature design theories, steel bridges have self-heavy, poor mobility, and labor-intensive operations. Major defects make it difficult to meet the ever-increasing and demanding requirements of mobile support tasks at this stage. Judging from several geological disaster rush construction missions that have occurred frequently in recen...
