Abstract
Abstract A liner system for retaining liquid in a storage tank. The liner system includes a continuous metallic liner which has sides which are substantially coextensive with the sidewalls of the tank and a bottom which is substantially coextensive with the floor of the tank. Upright expansion joints, provided in the sides of the liner, compensate for expansion and contraction of the sides in a circumferential direction and expansion joints, provided in the bottom of the liner, compensate for expansion and contraction in the bottom of the liner. Hanger members are secured to the upper portion of the tank and are resiliently mounted thereto. The upper end of the sides of the liner engage the resiliently mounted hangers so as to compensate for expansion and contraction of the liner in a vertical direction.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
144 words
A system for retaining liquid in a storage tank structure, said system comprising a storage tank having an upper portion, sidewalls, and a floor, continuous liner means having sides substantially coextensive with said sidewalls and having a bottom substantially coextensive with said floor, upright expansion joint sections integrally joined to said sides of said liner means compensating for circumferential expansion and contraction of said sides, ringlike expansion joint sections integrally joined to said bottom of said liner means compensating for expansion and contraction of said bottom, hanger members resiliently secured to said upper portion of said tank structure, and means secured to the upper end portions of said sides of said liner means for engaging said hanger members whereby said sides are suspended in a position substantially coextensive with said sidewalls and said bottom is maintained in a position substantially coexteNsive with said floor.
Claim 2
Independent Claim
144 words
A system for retaining liquid in a storage tank structure, said system comprising a storage tank having an upper portion, sidewalls, and a floor, continuous liner means having sides substantially coextensive with said sidewalls and having a bottom substantially coextensive with said floor, upright expansion joint sections integrally joined to said sides of said liner means compensating for circumferential expansion and contraction of said sides, ringlike expansion joint sections integrally joined to said bottom of said liner means compensating for expansion and contraction of said bottom, hanger members resiliently secured to said upper portion of said tank structure, and means secured to the upper end portions of said sides of said liner means for engaging said hanger members whereby said sides are suspended in a position substantially coextensive with said sidewalls and said bottom is maintained in a position substantially coexteNsive with said floor.
Claim 3
Dependent Claim
47 words
The system of claim 1 wherein said upright expansion joint sections in said sides extend to intersect said ringlike expansion joint sections in said bottom so as to allow for movement of said liner means in all directions at the intersection between said side and said bottom.
Claim 4
Dependent Claim
27 words
The system of claim 1 wherein the upper portion of said storage tank is above the ground and said hanger members extend outwardly above said upper portion.
Claim 5
Dependent Claim
36 words
The system of claim 1 wherein the upper portion of said storage tank structure is below the ground and the said hanger members are enclosed within said storage tanks and extend downwardly from said upper portion.
Claim 6
Dependent Claim
35 words
The system of claim 1 wherein said hanger members include spring means for resiliently supporting said sides in a vertical direction to compensate for vertical expansion and contraction of said sides of said liner means.
Claim 7
Dependent Claim
49 words
The system of claim 5 wherein said upright expansion joint sections and said ringlike expansion joint sections intersect so as to compensate for expansion and contraction in all directions at the intersection of said side and said bottom, thereby avoiding excessive stresses in said bottom of said liner means.
Claim 8
Dependent Claim
22 words
The system of claim 1 wherein said liner means is a flexible metallic material, said expansion joint means generally comprising corrugated sections.
Claim 9
Dependent Claim
52 words
The system of claim 1 wherein the said liner means comprise a plurality of planar substantially flexible metallic material sections welded together in a desired configuration so as to provide continuous liner means, and said expansion joint sections comprises unitary corrugated metallic members united to the planar portions of said liner means.
Claim 10
Dependent Claim
57 words
The system of claim 1 wherein said first expansion joint sections comprise substantially upright metallic corrugations, said second expansion joint sections integrally joined to said bottom of said liner means, said upright corrugations extend into said ringlike sections, and the outermost of said ringlike portions intersect the said extending portions of said upright corrugations in said sides.
Claim 11
Dependent Claim
31 words
The system of claim 1 wherein said hanger members comprise support members resiliently mounted in a vertical direction to compensate for expansion and contraction of said sides in a vertical direction.
