Structured adhesive system
View Patent ↗A construction configuration for a building includes a fixture adhered to a framing structure with an adhesive system. The adhesive system has an outer pressure sensitive adhesive material, an inner pressure sensitive adhesive material, a bonding adhesive material, and at least one spacer material. The spacer material has at least one opening for containing a desired quantity of the bonding adhesive material.
1. A construction configuration for a building comprising:
a building covering material adhered to a framing structure with a bonding system, the bonding system having the following structure:
an outer pressure sensitive adhesive adhered to the building covering material;
an inner pressure sensitive adhesive adhered to the framing structure;
at least one spacer positioned in an area defined between the inner and outer pressure sensitive adhesives, wherein the at least one spacer defines at least one opening between the inner and outer pressure sensitive adhesives; and
a bonding adhesive positioned within the at least one opening defined by the spacer and in contact with at least one of the building covering materials or framing structure, wherein the bonding adhesive is a curable adhesive configured to increase in strength overtime.
2. The bonding system of claim 1 , further including a first removable film removably adhered to the outer pressure sensitive adhesive and a second removable film removably adhered to the inner pressure sensitive adhesive.
3. The bonding system of claim 2 , wherein the first and the second removable films substantially prevent the bonding adhesive from setting or curing until the first and second removable films are removed from the bonding system.
4. The construction configuration of claim 1 , wherein the spacer comprises a material adapted to isolate, absorb and/or damp sound energy.
5. The bonding system of claim 4 , wherein the spacer converts sound energy to heat.
6. The bonding system of claim 5 , wherein the heat formed from the sound energy is used to aid in the curing of the bonding adhesive.
7. The bonding system of claim 1 , wherein the bonding adhesive is in contact with both the building covering material and the framing structure.
8. The bonding system of claim 1 , wherein the spacer has a uniform thickness.
9. The bonding system of claim 1 , wherein the spacer has a baffled pattern.
10. The construction configuration of claim 1 , wherein the spacer substantially fills the area between the inner and outer pressure sensitive adhesive materials.
11. The construction configuration of claim 1 , wherein the opening in the spacer has a depth and width such that the construction configuration has a desired vibration isolation at specified frequencies.
12. The construction configuration of claim 1 , wherein the outer and inner pressure sensitive adhesive provide an immediate adhering strength that allows the building covering to initially be held in place on the framing structure, and wherein the bonding adhesive sets or cures over tune.
13. The construction configuration of claim 1 , wherein the bonding system provides an outer bonding surface area which is defined by an outer pressure sensitive adhesive bonding surface area and a first bonding adhesive surface area; and wherein the bonding system provides an inner bonding surface area which is defined by an outer pressure sensitive adhesive bonding area and a second bonding adhesive surface area.
14. The construction configuration of claim 1 , wherein the bonding adhesive comprises a moisture curable polyurethane in the form of a high viscosity, thixotropic paste with isocyanate functionality.
15. The construction configuration of claim 1 , wherein the bonding adhesive has, in a cured state, a tensile strength that is at least twice that of the outer and inner pressure sensitive adhesive.
16. The construction configuration of claim 1 , wherein the bonding adhesive has, in a cured state, a tensile strength at least two orders of magnitude greater than that of the outer and inner pressure sensitive adhesive.
17. The construction configuration of claim 1 , wherein the outer and inner pressure sensitive adhesive and the bonding adhesive are inert with respect to each other such that no unfavorable chemical reaction occurs between the outer and inner pressure sensitive adhesive and the bonding adhesive.
18. The construction configuration of claim 1 , wherein the bonding system has a tape or strip configuration.
19. The construction configuration of claim 1 , wherein the bonding system has a generally circular shape.
20. The construction configuration of claim 1 , wherein the bonding system includes more than one opening.
