Abstract
A cover assembly for bridging an opening located in an expansion joint between two spaced-apart structural members. The cover assembly includes a coverplate having a rigid plate member that is engaged with a resilient elastomeric cover. The cover assembly is affixed to the underlying structural members by base members. The proper positioning of the cover assembly within the expansion joint gap is maintained through a positioning assembly that is engaged with the coverplate and base members.
Claims28
A cover assembly for a gap between structural members comprising:
- at least one base member affixed to at least one of said structural members;
- a coverplate comprising:
- an elongated resilient cover having a load bearing surface opposite a support surface;
- and
- a plurality of spaced apart rigid plate members engaged with said elongated resilient cover;
- wherein one of said plurality of spaced apart rigid plate members comprises a gap bridging rigid plate member which bridges said gap between said structural members;
- wherein the remainder of said plurality of spaced apart rigid plate members extend along opposite lateral sides of said gap bridging rigid plate member for allowing elastic deformation of said elongated resilient cover;
- and
- wherein the elongated resilient cover is capable of applying a biasing force in a substantially vertical direction to urge said rigid plate members which extend along opposite lateral sides of said gap bridging rigid plate member cover toward the horizontal structural members while the elongated resilient is resiliently deformed by traffic traversing said load bearing surface;
- and
- a positioning assembly which comprises a rotatable member which is engaged to said coverplate and said at least one base member.
An expansion joint for a building structure comprising:
- two spaced structural members defining a gap therebetween;
- at least one base member affixed to at least one of said structural members;
- a coverplate comprising:
- an elongated resilient cover having a load bearing surface opposite a support surface;
- and
- a plurality of spaced apart rigid plate members engaged with said elongated resilient cover;
- wherein one of said plurality of spaced apart rigid plate members comprises a gap bridging rigid plate member which bridges said gap between said structural members;
- wherein the remainder of said plurality of spaced apart rigid plate members extend along opposite lateral sides of said gap bridging rigid plate member for allowing elastic deformation of said elongated resilient cover;
- and
- wherein the elongated resilient cover is capable of applying a biasing force in a substantially vertical direction to urge said rigid plate members which extend along opposite lateral sides of said gap bridging rigid plate member toward the horizontal structural members while the elongated resilient cover is resiliently deformed by traffic traversing said load bearing surface;
- and
- a positioning assembly which comprises a rotatable member which is engaged with said coverplate and at least one base member.
