Composite Girder Structure integrated with Cover Plate Temporary Bridge using such Structure and Constructing Method of such Temporary Bridge

摘要

The present invention relates to a " composite girder with a single plate structure " having improved structural stability, economical efficiency, and workability by integrally forming a louver plate and a housing sheath, " a method of constructing a hypothetical bridge " hypothetical bridge " In the present invention, it comprises two rows (row) of houses 1 and a main board 4; The residential housing (1) is provided with a supporting member (7); A concave cutout groove 60 is formed in the main board 4; The supporting member 7 includes a bottom plate 71 and a pair of side plates 72. The side plate 72 has a protruding portion 720 formed at an upper portion thereof. The protruding extension 720 is fitted in the recessed cutout groove 60; When the single-piece composite synthetic girders 100 are disposed adjacent to each other and integrally formed, the side plates 72 are continuously joined to form a single flat surface, and the connecting fastening plates 78 are downwardly inserted into the side plates 72, When the connecting beams 5 are installed between the composite composite girders, the ends of the connecting beams 5 are sandwiched between the pair of side plates 72 to be integrated with each other. Also, in the present invention, a " temporary bridge construction method " in which a temporary bridge is constructed using such a composite girder integrated with a single-plate construction, and a " temporary bridge " constructed by such a construction method are provided.
