Abstract
A system for attaching a flexible expansion joint to the surface of a building such as the floor of a building. The system for attaching the joint is configured to secure the joint and provide, in effect, a form up to which a top coat of material such as concrete or asphalt can applied over an existing floor structure. The system provides a universal base unit upon which common extension units can be attached and stacked to vary the height of the form for the surface coat.
Claims23
An adjustable height expansion joint assembly for bridging an expansion gap in a floor or roof, the assembly is attachable to surfaces of the floor or roof adjacent to the gap, the assembly comprising:
- a pair of elongated base supports each including a flange which provides an attachment to a respective said surface, and a first interface having a first attachment configuration, each flange including a lower surface which rests against and is parallel to a respective said surface, the first interface being displaced from and generally parallel to the lower surface;
- at least a pair of elongated extension members each having a first side including a second interface which includes a second attachment configuration which mates with the first interface to join the elongated extension member to the respective elongated base support, each elongated extension member further including a second side opposite to and generally parallel with the first side, the second side including a third interface having a third attachment configuration, the third attachment configuration being the same as the first attachment configuration;
- and
- an elongated expansion joint including a pair of flanges attachable to a respective said third interfaces to bridge a gap between the surfaces;
- wherein the first attachment configuration includes at least three elongated walls;
- and
- wherein two opposing walls of the at least three elongated walls include a plurality of opposed notches which cooperate to provide a location into which a threaded screw can be engaged.
An assembly for forming the edge of a top coating applied to a floor or roof and the assembly being attachable to a surface at the edge of the floor or roof adjacent to an expansion gap, the assembly being configured to support one side of an elongated expansion joint which bridges the expansion gap, the assembly comprising:
- an elongated base support including a flange which provides an attachment to a respective said surface, and a first interface having a first attachment configuration, the flange including a lower surface which rests against and is parallel to a respective said surface, the first interface being displaced from and generally parallel to the lower surface at a first distance;
- and
- a first elongated extension member having a first side including a second interface which includes a second attachment configuration mated with the first interface to join the elongated extension member to the respective elongated base support, the first elongated extension member further including a second side displaced at a second distance from, opposite to and generally parallel with the first side, the second side including a third interface having the first a third attachment configuration, the third attachment configuration being the same as the first attachment configuration, the top coating having a thickness defined by at least the sum of the first and second distances, wherein one side of the expansion joint is attached to the third interface;
- wherein the first attachment configuration includes at least three elongated walls;
- and
- wherein two opposing walls of the at least three elongated walls include a plurality of opposed notches which cooperate to provide a location into which a threaded screw can be engaged.
A method for bridging an expansion gap in a floor or roof and forming the edge for a top coating applied to the surface of a respective floor or roof, the method comprising:
- attaching a flange of an elongated base support to the surface, the base support having a first interface having a first attachment configuration, the first interface being displaced from and generally parallel to the lower surface at a first distance;
- attaching at least a first elongated extension members to the elongated base, the elongated extension member having a first side including a second interface which includes a second attachment configuration engaged with the first interface, the elongated extension member further including a second side displaced at a second distance from, opposite to and generally parallel with the first side, the second side including a third interface having the first attachment configuration;
- and
- attaching one side of the expansion joint to the third interface, the top coating having a thickness defined by at least the sum of the first and second distances;
- wherein the step of attaching one side of the expansion joint to the third interface comprises:
- inserting an engagement extension of a flange of the expansion joint into a channel defined by two elongated walls of the third interface;
- positioning an angle member over the flange so that the flange is between the third interface and the angle member;
- and
- inserting a fastener through the angle member and the flange into the same channel as the engagement extension, the fastener engaging a plurality of opposed notches formed into the two elongated walls.
