Bridge structure

Abstract

The subject invention is an improved bridge structure comprising the use of both arch structural support systems along with suspension systems, combined together to support a multiple bridge support structure, with such multiple support systems being focused and combined through a unitary member in a center portion of the bridge, with the unitary member being an under support member in one embodiment, with such under support member supporting a portion of the bridge deck. More particularly, the subject invention is focused on utilizing multiple structural support systems for a bridge, with such multiple support systems being centered on a longitudinally extending secondary under support member, which is supported and held partially by the supplementary bridge support system, such secondary support member structurally having multiple and varied support systems and being adapted to provide an under support system as a supplementary support mechanism for the bridge structure. In summary, the subject invention comprises a secondary support system for a bridge to provide additional support to the primary support system for the bridge, such secondary support system having its forces focused on an undersupport system that is positioned beneath the bridge deck as an undersupport member that helps hold the bridge deck, along with the support provided by the primary support system.

1 . A supplemental support system for a bridge having a deck for vehicular traffic with such deck having an upper surface and a lower surface, and wherein such bridge has primary support members for supporting the bridge deck, said supplemental support system comprising: 
 (A) a longitudinally extending under-support member, said under-support member having an upper surface and a lower surface and wherein the upper surface of the under-support member is adapted to embrace a portion of the lower surface of the bridge deck;    (B) a suspension support system for supplementary support of said bridge, said suspension support system having one or more support cables attached to portions of said under-support member for purposes of holding said under-support member up against the under surface of the bridge deck for support purposes to supplement the support of the primary support system.    
     
     
         2 . A support system for a bridge having a bridge deck with an under surface comprising: 
 (A) a base under support member having an upper surface and a lower surface    (B) support system means for said bridge and bridge deck, said support means having connecting support means, said support means being connected through said connecting and support means to said under-support member to support said under-support member up against a portion of the under surface of the bridge deck.    
     
     
         3 . A multiple force support system for a bridge having a deck for vehicular traffic, with such deck having an upper surface and a lower surface, and wherein such bridge has primary support members for supporting the bridge deck, comprising: 
 (A) a longitudinally extending under-support member, said under-support member having an upper surface and a lower surface, and wherein said under-support member is adapted to be support up against a portion of the lower surface of the bridge deck;    (B) a bridge suspension support system having support means in the form of suspension cables connected to said under-support member to support said under-support member up against the lower surface of the bridge deck.
