Helically-packaged expansion joint seal system prepared for change in direction
A foam-based expansion joint seal system packaging which facilitates transport and reduces the need for internal splices.
1. An expansion joint seal system, comprising:
a longitudinal body of foam in compression;
the longitudinal body of foam in compression impregnated with a fire retardant additive; and
a casing in tension helically compressively encircling the longitudinal body of foam in compression and a water-resistant constituent.
2. The expansion joint seal system of claim 1 , further comprising:
the casing having an internal surface, the internal surface contacting the longitudinal body of foam, the internal surface having a low friction coefficient.
3. The expansion joint seal system of claim 1 , wherein a successive section of the casing overlaps a prior section of the casing by 15%.
4. The expansion joint seal system of claim 1 , further comprising:
a board intermediate the longitudinal body of foam in compression and the casing at a first side of the casing, the board having a board height, the longitudinal body of foam in compression having a foam body height, the board height being greater than or equal to the foam body height.
5. The expansion joint seal system of claim 4 , further comprising:
a second board intermediate the longitudinal body of foam in compression and the casing at a second side of the casing, the second board having a second board height, the second board height being greater than or equal to the foam body height.
6. The expansion joint seal system of claim 5 , wherein the board and the second board are in parallel planes.
7. The expansion joint seal system of claim 5 , wherein the board and the second board are askew, and wherein the board has a first end adjacent a first end of the longitudinal body of foam in compression, and the second board has a first end adjacent the first end of the longitudinal body of foam in compression.
8. The expansion joint seal system of claim 1 , wherein the casing is paper.
9. The expansion joint seal system of claim 1 , wherein the casing is inelastic.
10. The expansion joint seal system of claim 1 , wherein the longitudinal body of foam in compression has a length greater than ten feet.
11. The expansion joint seal of claim 1 , wherein the casing bears a distance indicator at regular intervals.
12. The expansion joint seal of claim 1 , wherein the longitudinal body of foam in compression is under compression laterally between a first sidewall and a second sidewall.
13. The expansion joint seal of claim 1 wherein the longitudinal body of foam in compression is under compression laterally between a first sidewall and a second sidewall and is under compression longitudinally.
14. The expansion joint seal of claim 1 wherein the longitudinal body of foam in compression is under compression laterally between a first sidewall and a second sidewall and the longitudinal body of foam in compression is under compression between a longitudinal body of foam top and a longitudinal body of foam bottom.
15. The expansion joint seal of claim 1 wherein the longitudinal body of foam in compression is under compression laterally between a first sidewall and a second sidewall, the longitudinal body of foam in compression is under compression longitudinally and the longitudinal body of foam in compression is under compression between a longitudinal body of foam top and a longitudinal body of foam bottom.
16. The expansion joint seal system of claim 1 , wherein the casing includes an external adhesive surface.
17. The expansion joint seal system of claim 1 , wherein the casing includes a heat sensitive coating.
18. The expansion joint seal system of claim 1 , wherein the casing includes a first chemically sensitive coating on a first surface and a second chemically sensitive coating on a second surface, the first chemically sensitive coating reactive to the second chemically sensitive coating bonding the first surface to the second surface.
