Abstract
Abstract Bridge or highway supporting structure of steel concrete or prestressed concrete for multiple section structure with columns disposed centrally of the cross-section of the bridge, a superstructure of beams in the form of slabs rigidly connected to the columns with at least one slab-shaped longitudinal girder and slab-shaped transverse beams of the same structural height as the longitudinal girders where the columns are slender in the direction longitudinally of the bridge supporting structure and relatively wider transversely thereof and connected with the transverse beams with a pedestal at the foot of each column, a foundation block below each pedestal and bearings intermediate the pedestal and the foundation block which are spaced transversely of the structure to permit tilting movement of the bridge in longitudinal direction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
142 words
Multiple section supporting structure for bridges and highways of reinforced or prestressed concrete comprising columns disposed centrally of the cross section of the structure, each section comprising a superstructure in the form of slab girders rigidly connected to said columns including a pair of slab shaped longitudinal girders and transverse slabs defining transverse beams, said transverse beams having substantially the same structural height as said longitudinal girders, said columns being relatively slender in the direction longitudinally of the structure and having relatively wider sides transversely thereof and being rigidly connected along said relatively wider sides with said transverse beams, a pedestal at the foot of each column, a foundation block below each pedestal and bearing elements intermediate each pedestal and foundation block, said bearing elements being spaced transversely of the structure and permitting tilting movement in a direction longitudinally of the structure.
Claim 2
Dependent Claim
142 words
Multiple section supporting structure for bridges and highways of reinforced or prestressed concrete comprising columns disposed centrally of the cross section of the structure, each section comprising a superstructure in the form of slab girders rigidly connected to said columns including a pair of slab shaped longitudinal girders and transverse slabs defining transverse beams, said transverse beams having substantially the same structural height as said longitudinal girders, said columns being relatively slender in the direction longitudinally of the structure and having relatively wider sides transversely thereof and being rigidly connected along said relatively wider sides with said transverse beams, a pedestal at the foot of each column, a foundation block below each pedestal and bearing elements intermediate each pedestal and foundation block, said bearing elements being spaced transversely of the structure and permitting tilting movement in a direction longitudinally of the structure.
Claim 3
Dependent Claim
27 words
Bridge supporting structure in accordance with claim 1 where some of said columns are supported on stationary tilting bearings and others are supported on tilting roller bearings.
Claim 4
Dependent Claim
37 words
Bridge supporting structure in accordance with claim 1 where said columns widen at the top to form a mushroom-like expansion on said transverse beam with which they are connected and expand at the bottom toward said pedestal.
Claim 5
Dependent Claim
38 words
Bridge supporting structure in accordance with claim 1, where the width of the columns is approximately one-eighth of the width of the bridge and the spacing of the bearings is approximately one-fourth of the width of the bridge.
Claim 6
Dependent Claim
25 words
Bridge supporting structure in accordance with claim 1 comprising a pair of longitudinal girders disposed at the quarter points of the width of said bridge.
