Open Web Dissymmetric Beam Construction

US Patent:
6442908, Sep 3, 2002
Filed:
Apr 26, 2000
Appl. No.:
09/559885
Inventors:
Peter A. Naccarato - Philadelphia PA 19135
John A. Costanza - Cherry Hill NJ 08033
Daniel G. Fisher - Cherry Hill NJ 08034
International Classification:
E04B 120
US Classification:
522368, 52250, 52435
Abstract:
An improved structural framing system and associated method of construction is disclosed wherein an open web dissymmetric steel beam fabricated having a plurality of trapezoidal openings formed along the web thereof between a narrowed, thickened top flange and a widened bottom flange is horizontally disposed and supported between adjacent vertical columns erected on conventional foundations. The dissymmetric beam is preferably fabricated from a standard rolled, wide flange beam split longitudinally according to a specific cutting pattern to produce substantially identical open web beam sections having a single wide flange. A flat bar plate is then welded along the open web beam section to provide the top flange and thereby produce the dissymmetric beam for use in the present system. Standard hollow core sections of precast concrete plank are assembled together perpendicularly to the open web dissymmetric beam and supported upon the bottom flange on either side thereof so that the open web of the beam is centrally disposed between end surfaces of the plank sections in substantially the same horizontal plane. A high-strength grout mixture applied to the assembled beam and plank sections is made to flow completely through the web openings in a circulatory manner thereby creating a substantially monolithic concrete encasement around the dissymmetric beam that improves the resulting composite action and mechanical interlock between the steel beam and concrete plank and prevents loss of strength due to separation of the grout from either side of the beam.

Dissymetric Beam Construction

US Patent:
5704181, Jan 6, 1998
Filed:
Apr 13, 1995
Appl. No.:
8/421560
Inventors:
Daniel G. Fisher - Cherry Hill NJ
John A. Costanza - Haddonfield NJ
Peter A. Naccarato - Philadelphia PA
International Classification:
E04B 523
US Classification:
52438
Abstract:
An improved structural framing system and associated method for constructing same wherein a specially configured dissymetric steel beam is horizontally disposed and supported between adjacent vertical columns erected on conventional foundations. The dissymetric beam is fabricated having a compressed, block-like top flange formed opposite a substantially flattened bottom flange and integrally connected thereto by an intermediate web. Standard hollow core sections of precast, prestressed concrete plank spanning perpendicular to the dissymetric beam are disposed on either side of the beam and together assembled thereto so that the web of the beam is disposed centrally between facing edges of the plank sections with the bottom flange of the beam supporting the lower surface of the plank and the top flange substantially aligned with the upper plank surface. Grouting of the assembled beam and plank sections with a high-strength grout mixture provides total encasement of the dissymetric beam and produces a composite action between the beam and plank that significantly increases load capacity of the system.
