Abstract
Abstract A watertight expansion joint sealing section for the gap between two adjacent floor surfaces comprising an elastic bridging strip member having its two longitudinal edges secured to a rigid elongated intermediate member which in turn is secured to the vertical leg of an associated bracket which has a horizontal leg secured to the floor structure on each side of the gap. A cover strip is positioned over each of the longitudinal edges of the bridging strip and compressed there-against to form a watertight seal.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
149 words
A waterproof expansion joint sealing section for the gap between adjacent floor surfaces of a structure comprising an elastic bridging member having longitudinally directed edges, an anchoring bracket having a vertical leg and a horizontal leg extending essentially parallel to the floor, means securing said horizontal leg of each of said brackets to an associated floor surface on each side of the gap therebetween, an intermediate member secured to each of said vertical legs and rising therefrom, an elastic covering strip disposed parallel to the length of the gap, each of said longitudinal edges of the elastic bridging member being disposed in overlapping relation to a longitudinal edge of said covering strip, a retaining strip extending over said two overlapping longitudinal edges, means co-acting with said intermediate member to maintain said retaining strip in compression relative to said overlapping edges against said intermediate member to provide a watertight connection.
Claim 2
Dependent Claim
149 words
A waterproof expansion joint sealing section for the gap between adjacent floor surfaces of a structure comprising an elastic bridging member having longitudinally directed edges, an anchoring bracket having a vertical leg and a horizontal leg extending essentially parallel to the floor, means securing said horizontal leg of each of said brackets to an associated floor surface on each side of the gap therebetween, an intermediate member secured to each of said vertical legs and rising therefrom, an elastic covering strip disposed parallel to the length of the gap, each of said longitudinal edges of the elastic bridging member being disposed in overlapping relation to a longitudinal edge of said covering strip, a retaining strip extending over said two overlapping longitudinal edges, means co-acting with said intermediate member to maintain said retaining strip in compression relative to said overlapping edges against said intermediate member to provide a watertight connection.
Claim 3
Dependent Claim
91 words
An expansion joint sealing section in accordance with claim 1 in which each said intermediate members has under the overlap region of said two longitudinal edges, a bearing surface oriented parallel to the floor of the structure, said bearing surface having two grooves extending along the length of the intermediate member, one of said grooves being adapted to receive a web extending from the bridging member outside the overlap region while the other groove is adapted to receive under press-fit a web extending from the cover strip within the overlap region.
Claim 4
Dependent Claim
44 words
Expansion joint sealing section, according to claim 1 in which threaded bores are provided in the intermediate section at intervals along the length thereof between said grooves into which threaded bolts passing through the two longitudinal edges in the overlap region can be screwed.
Claim 5
Dependent Claim
88 words
Expansion joint sealing section according to claim 1 in which each retaining strip is provided with a depending edge strip angularly bent downwardly toward the floor of the structure, said edge strip being spaced from the side face of an associated intermediate member away from the joint according to the thickness of the cover strip, the latter being angularly bent and positioned between the side face and the edge strip, a hardenable or permanently elastic material being moldable to a layer which forms the surface of the floor.
Claim 6
Dependent Claim
56 words
Expansion joint sealing section according to claim 1, in which the effective width of each cover strip extends in a Z-shaped configuration, over and beyond the length of the horizontal leg of the anchoring bracket parallel to the floor and the outer longitudinal edge of the cover strip is in watertight relationship with the floor structure.
