Abstract
A prestressed concrete panel for a bridge construction includes a first section having at least one tension member extending therethrough. A second section of the panel is spaced from the first section to form a gap therebetween. The tension member extends through the second section also and across the gap. The gap is adapted to be aligned above a support beam or girder. At least one compression member also extends between the first and second sections and across the gap in such a manner such that the gap is maintained against the tension forces of the tension member.
Claims22
A prestressed concrete panel for bridge construction comprising:
- a first section having at least one tension member extending therethrough;
- a second section spaced from said first section to form a gap therebetween, wherein said tension member extends through said second section and across said gap, said gap adapted to be aligned above a support member;
- at least one compression member extending between said first and second sections in such a manner to maintain said gap against the tension forces of said tension member;
- and
- a connecting assembly including a splice member and a locking member, wherein said panel and an adjacent panel have a reinforcing member extending therethrough with at least one exposed end, said splice member overlapping the exposed end of each reinforcing member of the adjacent panels, and said locking member encircling said splice member and said exposed ends.
A connecting assembly adapted to connect two adjacent panels of a bridge deck construction, each panel having a reinforcing member therethrough with at least one exposed end, the assembly comprising:
- a splice member overlapping the exposed end of each reinforcing member of the adjacent panels;
- and
- a locking member surrounding said splice member and said exposed ends.
A bridge construction comprising:
- at least two concrete panels, each panel having a first section with at least one tension member extending therethrough and a second section spaced from said first section to form a gap therebetween, wherein said tension member extends through said second section and across said gap, said gap adapted to be aligned above a support, each panel having at least one compression member extending between said first and second sections of such panel in such a manner to maintain said gap against the tension forces of said tension member, each panel having a reinforcing member extending therethrough with at least one exposed end, said panels disposed in an adjacent manner such that the exposed ends of the adjacent panels generally align with one another;
- a splice member overlapping the exposed end of each reinforcing member of the adjacent panels;
- a locking member surrounding said splice member and said exposed ends;
- and
- a material cast such that the material surrounds said splice member and said locking member.
A method of producing a crowned prestressed concrete panel, said method comprising:
- putting an elongated member into tension;
- deforming said elongated member from a linear path;
- pouring a concrete mixture around said tensioned elongated member and forming the mixture so that it generally follows the deformed path of the elongated member;
- allowing said concrete mixture to cure;
- and
- releasing the tension on said elongated member.
