Abstract
Abstract A mounting support for a shaped elastomeric seal for a roadway or the like, wherein the support is readily mounted in a clearance position within the roadway expansion joint or void and cement is poured in situ about said support preparatory to the positioning of the elastomeric seal thereon. Eliminated are precast cement blocks and the like which heretofore complicated field installation of the elastomeric seal.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
152 words
In combination, an elastomeric seal having an operative position in an expansion void bounded by facing side walls of a concrete roadway that is subject to expansion and contraction, and a positioning support construction for said elastomeric seal comprising at least two support rods disposed in spaced relation lengthwise of said void adjacent each said bounding wall thereof, a pair of cooperating spaced apart support bodies having a combined shape to accommodate said elastomeric seal thereon, support means disposed in said void beneath said support bodies so as to provide an elevated operative position to said support bodies lengthwise of said void, and connecting means on said support bodies extending from spaced lengthwise locations therealong into connected relation with a cooperating one of said support rods, whereby cement subsequently deposited in situ in said void hardens about said connecting means to contribute to the engagement of said support bodies by said cement.
Claim 2
Dependent Claim
152 words
In combination, an elastomeric seal having an operative position in an expansion void bounded by facing side walls of a concrete roadway that is subject to expansion and contraction, and a positioning support construction for said elastomeric seal comprising at least two support rods disposed in spaced relation lengthwise of said void adjacent each said bounding wall thereof, a pair of cooperating spaced apart support bodies having a combined shape to accommodate said elastomeric seal thereon, support means disposed in said void beneath said support bodies so as to provide an elevated operative position to said support bodies lengthwise of said void, and connecting means on said support bodies extending from spaced lengthwise locations therealong into connected relation with a cooperating one of said support rods, whereby cement subsequently deposited in situ in said void hardens about said connecting means to contribute to the engagement of said support bodies by said cement.
Claim 3
Dependent Claim
36 words
The elastomeric seal positioning support construction as defined in claim 1 wherein each said support body is fabricated of metal and each said connecting means is partially severed and then bent into said extending relation therefrom.
Claim 4
Dependent Claim
41 words
The elastomeric seal positioning support construction as defined in claim 2 including a waterproof member in covering relation over said support bodies to prevent seepage of said in situ cement through openings in said bodies formerly occupied by said connecting means.
Claim 5
Dependent Claim
31 words
The elastomeric seal positioning support construction as defined in claim 2 wherein each said support body has a pair of facing vertically oriented walls defining a tapered elastomeric seal-engaging compartment therebetween.
