Abstract

The present invention resides in a structure which is particularly advantageous for the manufacture of prefabricated buildings. The structure uses a uniquely formulated exterior wall panel that is bonded to a frame of support members. A connecting member may be used to accommodate support members having a wide variety of cross-sectional shapes. The structure may have a unique cementitious composition that allows it to be fire and insect resistant and generally impervious to moisture.

Claims

1. A structure, comprising:

a panel;

a frame comprising support members, wherein each of the support members has a defined length, a center portion of a defined height and thickness, and first and second opposed sides each of a defined width, wherein a cross section of the support members presents a defined shape consisting of the center portion in combination with the first and second opposed sides;

bonding pads that bond the panel to the frame by attaching to the frame and to one or more of the first opposed sides of the support members, wherein the bonding pads enclose one or more segments of the first opposed side(s) of one or more of the support members, and wherein the panel and the bonding pads are prepared from a cured/hardened moldable building material; and

one or more connecting members, the connecting member(s) being interposed between one or more of the support members and the panel at the point where the bonding pad(s) encloses segment(s) of the first opposed side(s) of one or more of the support members, the connecting member(s) having an extended portion having a width that is greater than the width of the first opposed side(s), and the connecting member(s) being optionally affixed to the one or more support members.

2. A structure according to claim 1, wherein the moldable building material is a cementitious material.

3. A structure according to claim 2, wherein, prior to cure, the cementitious material comprises, by weight, greater than about 25% cement, less than about 55% sand, less than about 5% glass fibers, greater than about 1.6% acrylic polymer, and greater than about 11% water.

4. A structure according to claim 3, wherein, prior to cure, the cementitious material comprises, by weight, in the range of about 25-55% cement, in the range of about 25-55% sand, in the range of about 1-5% glass fibers, in the range of about 1-10% acrylic polymer, and in the range of about 10-15% water.

5. A structure according to claim 3, wherein, prior to cure, the cementitious material comprises a composition, by weight, of about 40.3% cement, about 40.3% sand, about 2.9% glass fibers, about 4.0% acrylic polymer, about 0.4% super plasticizer and about 12.1% water.

6. A structure according to claim 2, wherein the cementitious material contains reinforcing fibers.

7. A structure according to claim 6, wherein the reinforcing fibers are steel, fiberglass, polymer, graphite, or Kevlar®

.

8. A structure according to claim 1, wherein the moldable building material is a polymer-based resin.

9. A structure according to claim 8, wherein the polymer-based resin contains fiberglass.

10. A structure according to claim 1, wherein the support members are metal, wood, or fiberglass.

11. A structure according to claim 1, wherein the extended portion of the connecting member(s) has one or more perforations for admitting the moldable building material therethrough, prior to curing or hardening of the moldable building material.

12. A structure according to claim 1, wherein each connecting member is entirely contained within the corresponding bonding pad.

13. A structure according to claim 1, wherein the defined shape defines a structure that has a width greater than the thickness of the center portion, thereby providing an anchor point for the bonding pads.

14. A structure according to claim 1, wherein the cross section of the support members appears as an I, an L, an H, a C, a J, a T, a Z, a rectangle, or a pair of opposed triangles separated by the center portion.

15. A structure according to claim 1, wherein the frame is load-bearing.

16. A structure, comprising:

a panel formed of a cementitious building material;

a frame comprising support members, wherein each of the support members has a defined length, a center portion of a defined height and thickness, and first and second opposed sides each of a defined width, wherein a cross section of the support members presents a defined shape consisting of the center portion in combination with the first and second opposed sides;

a plurality of bonding patches that bond the panel to the frame by attaching to the frame and to one or more of the first opposed sides of the support members, the support member(s) having spaced-apart bonding patches along the length of the support member, wherein the plurality of bonding patches are prepared from a cured/hardened moldable cementitious building material, and the bonding patches enclose one or more segments of the first side(s) of one or more of the support members; and

a connecting member, the connecting member being interposed between one or more of the support members and the panel at the point where the bonding patches enclose segments of the first opposed side(s) of one or more of the support members, and wherein the connecting member is optionally affixed to the one or more support members.

17. A structure, comprising:

a panel;

a frame comprising support members, wherein each of the support members has a defined length, a center portion of a defined height and thickness, and first and second opposed sides each of a defined width, wherein a cross section of the support members presents a defined shape consisting of the center portion in combination with the first and second opposed sides;

bonding pads that bond the panel to the frame by attaching to the frame and to one or more of the first opposed sides of the support members, wherein the bonding pads enclose one or more segments of the first opposed side(s) of one or more of the support members, and wherein the panel and the bonding pads are prepared from a cured/hardened moldable building material; and

one or more connecting members, the connecting member(s) being interposed between one or more of the support members and the panel at the point(s) where the bonding pad(s) enclose segment(s) of the first opposed side(s) of one or more of the support members, and the connecting member(s) extending along the length of the support member(s) beyond the enclosed segment(s) of the support member(s).

18. A structure, comprising:

a panel;

a frame comprising support members, wherein each of the support members has a defined length, a center portion of a defined height and thickness, and first and second opposed sides each of a defined width, wherein a cross section of the support members presents a defined shape consisting of the center portion in combination with the first and second opposed sides;

bonding pads that bond the panel to the frame by attaching to the frame and to one or more of the first opposed sides of the support members, wherein the bonding pads enclose one or more segments of the first opposed side(s) of one or more of the support members, and wherein the panel and the bonding pads are prepared from a cured/hardened moldable building material; and

one or more connecting members, the connecting member(s) being interposed between one or more of the support members and the panel at the point(s) where the bonding pad(s) enclose segment(s) of the first opposed side(s) of one or more of the support members, and the connecting member(s) wrapping around a portion of the support member.

19. A structure, comprising:

a panel;

a frame comprising support members, wherein each of the support members has a defined length, a center portion of a defined height and thickness, and first and second opposed sides each of a defined width, wherein a cross section of the support members presents a defined shape consisting of the center portion in combination with the first and second opposed sides;
