Abstract

A modular sealant system configured to provide customizable sealing solutions for various applications, comprising interchangeable components that facilitate tailored installation, maintenance, and adaptability to diverse environmental and structural conditions. A modular sealant system can comprise a modular wall or frame consisting of horizontals and vertical members, one or more panels, one or more backers, a sealant.

Claims (42)

1 . A modular sealant system consisting of:

a first panel selectively coupled to a first horizontal member of a modular wall;

a second panel selectively coupled to a second horizontal member of the modular wall;

a backer, wherein the backer is:

selectively coupled to a first prong of a first vertical member of the modular wall and selectively coupled to a first prong of a second vertical member of the modular wall, and

configured to register the first panel and the second panel relative to each other;

a geometry defined by an edge of the first panel, an edge of the second panel, and an end face of the backer; and

a sealant having elastomeric properties configured to adhere and conform to the geometry;

wherein the sealant occupies the geometry and forms a seal configured to prevent an ingress or an egress of air, moisture, and contaminants.

2 . A modular sealant system comprising:

a first panel selectively coupled to a first horizontal member of a modular wall;

a second panel selectively coupled a second horizontal member of the modular wall;

a backer in communication with the modular wall, the backer is selectively coupled to a first prong of a first vertical member of the modular wall and selectively coupled to a first prong of a second vertical member of the modular wall, wherein the backer is configured to register the first panel and the second panel relative to each other in a predefined orientation such that the first panel and the second panel are removably attached to the modular wall;

a geometry defined by an edge of the first panel, an edge of the second panel, and an end face of the backer; and

a mastic sealant comprising elastomeric properties, configured to adhere and conform to the geometry;

wherein the sealant completely occupies the geometry and forms a seal configured to prevent an ingress or an egress of air, moisture, and contaminants.

3 . The modular sealant system of claim 2 , wherein the backer is a frame member of the modular wall.

4 . The modular sealant system of claim 2 , wherein the backer has a length substantially similar to a height or length of the modular wall.

5 . The modular sealant system of claim 2 , wherein the backer further comprises a guide disposed along a length of the end face.

6 . The modular sealant system of claim 2 wherein:

the backer selectively couples to a corner vertical member.

7 . The modular sealant system of claim 6 , wherein the end face is curved and has a constant radius.

8 . The modular sealant system of claim 2 , further comprising:

the second panel selectively couples to the first horizontal member;

a leveler configured to adjust an orientation of the modular sealant system relative to a floor; and

a stopper configured to create a seal between the second panel and the floor.

9 . The modular sealant system of claim 8 , wherein the floor is curved and is received in a space between the first horizontal member, the stopper, and the second panel.

10 . The modular sealant system of claim 2 , wherein the backer comprises a first piece and a second piece.

11 . The modular sealant system of claim 10 , wherein the first piece comprises one or more first barbs and one or more second barbs wherein:

the one or more first barbs extend from the end face;

the one or more second barbs are configured for coupling the first piece within a receiving slot defined by the second piece.

12 . The modular sealant system of claim 2 further comprising:

the second panel selectively couples to the first horizontal member; and

the backer is inserted into an internal portion of the first horizontal member.

13 . The modular sealant system of claim 12 , wherein the second panel is coupled to the first horizontal member by hanging, such that the second panel is suspended by the first horizontal member under a force of gravity.

14 . The modular sealant system of claim 12 , wherein the first horizontal member is configured to register the first panel and the second panel.

15 . A method of installing the modular sealant system of claim 2 , comprising;

assembling the modular wall comprising the first panel and the second panel;

installing the backer wherein the backer is in communication with a frame member of the modular wall; and

applying the sealant into the geometry defined by the edge of the first panel, the edge of the second panel, and the end face of the backer.

16 . The method of claim 15 , further comprising smoothing an outer surface of the sealant to make a level elevation and curing the sealant.

17 . The method of claim 15 , wherein a single installer completes each act.
