Composite complex profile and the process for its manufacturing

DETAILED DESCRIPTION I claim: 1.
A post comprising: a steel H-beam core formed with a central web and lateral flanges unitary with said web, each of said flanges being formed with an outwardly turned spur along the outer edge of an outer face thereof; a pair of steel sheets each having inwardly bent edges, each of said sheets bridging two spaced-apart flanges of said H-beam with the inwardly bent edges of said sheets form-fittingly engaged over the spurs of said flanges, said sheets lying parallel to said web and defining a pair of compartments with said web and inner surfaces of said flanges; an outer layer of colloidal concrete bonded directly to the steel of said sheets and said flanges and completely enveloping same; and inner layers of colloidal concrete bonded directly to surfaces of said flanges and said sheets defining said compartments and thereby lining same.
2.
The post defined in claim 1, further comprising a pointed pyramidal shoe fitted onto an end thereof and extending beyond said outer layer to facilitate pile driving of said post.
3.
The post defined in claim 1 wherein said steel sheets are outwardly convex.
4.
The post defined in claim 3 wherein said steel sheets are curved in cross section.
5.
The post defined in claim 3 wherein said steel sheets are angularly bent in cross section.
6.
The post defined in claim 1, claim 2, claim 3, claim 4 or claim 5, further comprising welds between each bent edge of a respective sheet and a respective flanges of said H-beam.




Description:
FIELD OF THE INVENTION This invention relates to a composite complex profile of steel and concrete.
BACKGROUND OF THE INVENTION Composite profiles of steel have been known for a long time.
Those profiles can make up assemblages of girders by themselves or with flat or contoured elements.
The composite profiles can serve as as posts or as other elements in construction waterway equipment, maritime gates, embankments or dikes.
Composite profiles of steel may also be used for the construction of buildings
