Abstract

The present disclosure relates generally to systems for providing a durable water-resistant and fire-resistant foam-based seal in the joint between adjacent panels. An expansion joint seal, which may be fire-resistant and/or water-resistant, is provided which includes one or more body members, a fire retardant member, which may be of an intumescent member, interspersed within the body member or members, a plurality of resilient members to provide a spring recovery force and fire resistance, and a connector of at least two of the resilient members, which connect each of the resilient members to a cover plant or may connect the two resilient members to one another.

First claim

What is claimed is:

1. An expansion joint seal, comprising:
a first body member, the first body member being resiliently, elastically compressible, the first body member having a first body member width between a first body member first side surface and a first body member second side surface and a first body member height between a first body member top surface and a first body member bottom surface, the first body member being a foam;
a first flexible sheeting, the first flexible sheeting proximate the first body member bottom surface and in contact with the first body member first side surface and the first body member second side surface, the first flexible sheeting has one or more properties selected from the group of vapor-impermeable, vapor low permeability, fire retardancy, intumescent, hydrophilic, and hydrophobic, the first flexible sheeting adhered to the first body member first side surface at least halfway from the first body member bottom surface to the first body member top surface, and the first flexible sheeting adhered to the first body member second side surface at least halfway from the first body member bottom surface to the first body member top surface, and the first flexible sheeting has a first flexible sheeting thickness;
a second body member, the second body member being resiliently, elastically compressible, the second body member having a second body member width between a second body member first side surface and a second body member second side surface and a second body member height between a second body member top surface and a second body member bottom surface the second body member being a foam;
the second body member width equivalent to the first body member width;

a second flexible sheeting, the second flexible sheeting proximate the second body member top surface and in contact with the second body member first side surface and the second body from the group of vapor-impermeable, vapor low permeability, fire retardancy, intumescent, hydrophilic, and hydrophobic, the second flexible sheeting adhered to the second body member first side surface at least halfway from the second body member bottom surface to the second body member top surface, and the second flexible sheeting, adhered to the second body member second side surface at least halfway from the second body member bottom surface to the second body member too surface, and the second flexible sheeting has a second flexible sheeting thickness,
the first flexible sheeting adjacent the second flexible sheeting;

the first flexible sheeting not contacting a second body member first side surface and the first flexible sheeting not contacting a second body member second side surface;
a third body member, the third body member having a third body member width, the third body member width not exceeding the greater of the one of the sum of the first body member width and twice the first flexible sheeting, thickness and the sum of the second body member width and twice the second flexible sheeting thickness, the third body member intermediate the first flexible sheeting and the second flexible sheeting, the third body member adhered to the first flexible sheeting and adhered to the second flexible sheeting, the third body member containing one or more materials selected from the group consisting of a sintering material, a thermally-insulating material, a hydrophilic material a hydrophobic material, a refractory material, an intumescing material, a fire retardant, and a metal oxide, and
a first interior member intermediate the first body member and the first flexible sheeting, the first interior member selected from one of a flexible enclosure and a solid body, the first interior member containing one or more materials selected from the group consisting of a sintering material, a thermally-insulating material, a hydrophilic material, a hydrophobic material, a refractory material, an intumescing material, a fire retardant, and a metal oxide.

2. The expansion joint seal of claim 1 , further comprising a second interior member intermediate the second body member and the second flexible sheeting, the second interior member selected from one of a flexible enclosure and a solid body, the second interior member containing one or more materials selected from the group consisting of a sintering material, a thermally-insulating material, a hydrophilic material, a hydrophobic material, a refractory material, an intumescing material, a fire retardant, and a metal oxide.

3. The expansion joint seal of claim 1 , wherein the second body member having a maximum joint width of more than six inches and wherein the second body member is adapted so a bottom surface temperature of a bottom of the second body member increases no more than 139° C. after sixty minutes when the joint, seal is exposed to heating according to the equation T=20+345*LOG(8*t+1), where t is time in minutes and T is temperature in C.

4. The expansion joint seal of claim 3 , wherein the joint seal is adapted to be cycled one of 500 times at 1 cycle per minute, 500 times at 10 cycles per minute and 100 cycles at 30 times per minute, without indication of stress, deformation or fatigue.

5. The expansion joint seal of claim 1 , wherein the second body member is adapted so a bottom surface temperature of a bottom of the second body member at a maximum joint width increases no more than 181° C. after sixty minutes when the joint seal is exposed to heating according to the equation T=20+345*LOG(8*t+1), where t is time in minutes and T is temperature in C.

6. An expansion joint seal, comprising:
a first body member, the first body member being resiliently, elastically compressible, the first body member having a first body member width between a first body member first side surface and a first body member second side surface and a first body member height between a first body member top surface and a first, body member bottom surface, the first body member being a foam;
a first flexible sheeting, the first flexible sheeting proximate the first body member bottom surface and in contact with the first body member first side surface and the first body member second side surface,
the first flexible sheeting having one or more properties selected from the group of vapor-impermeable, vapor low permeability, fire retardancy, intumescent, hydrophilic, and hydrophobic, the first flexible sheeting adhered to the first body member first side surface at least halfway from the first body member bottom surface to the first body member top surface, and the first flexible sheeting adhered to the first body member second side surface at least halfway from the first body member bottom surface to the first body member top surface, and the first flexible sheeting has a first flexible sheeting thickness:
a second body member, the second body member being resiliently, elastically compressible, the second body member having a second body member width between a second body member first side surface and a second body member second side surface and a second body member height between a second body member top surface and a second body member bottom surface,
