Abstract

The invention comprises a concrete form. The concrete form comprises a first panel having a first primary surface for contacting plastic concrete and a second primary surface opposite the first surface, wherein the first panel is made from a rigid plastic sheet or a metal sheet; and a second panel spaced from the second primary surface of the first panel, wherein the second panel is made from a rigid plastic sheet or a metal sheet. The concrete form also comprises a layer of insulating material disposed between the first panel and the second panel. A method of using the concrete form is also disclosed.

First claim

What is claimed is:

1. A method of forming concrete comprising:
placing plastic concrete in a concrete mold comprising:
a first horizontal concrete forming panel having a first primary surface adapted for forming and contacting plastic concrete and a second primary surface opposite the first primary surface, wherein the first concrete forming panel defines a plane;
a second horizontal panel having a first primary surface and a second primary surface opposite the first primary surface;
a first continuous layer of insulating material continuously contacting the second primary surface of the first concrete forming panel and the second primary surface of the second panel, the layer of insulating material substantially covering the second primary surface of the first panel;
a plurality of vertical side members, each of which has a first primary surface adapted for forming plastic concrete and a second primary surface opposite the first primary surface, wherein the first horizontal concrete forming panel and the plurality of vertical side members define a concrete mold cavity;
a second continuous layer of insulating material substantially covering the second primary surface of each of the plurality of vertical side members; and
a frame disposed on the first primary surface of the second panel, the frame comprising a plurality of bracing members oriented transversely with respect to the first primary surface of the second panel, wherein no portion of the frame is in the plane defined by the first concrete forming panel;

placing plastic concrete in the concrete mold, the plastic concrete having an exposed surface;
placing a removable third layer of insulating material over the exposed surface of the plastic concrete; and
leaving the plastic concrete in the concrete mold for a time sufficient to at least partially cure the plastic concrete.

2. The method of claim 1 , wherein the first and second continuous layers of insulating material each comprise a conductive heat insulating material or a radiant heat reflective material.

3. The method of claim 1 , wherein the first and second continuous layers of insulating material each have insulating properties equivalent to at least 0.25 inch of polystyrene foam.

4. The method of claim 1 , wherein the first and second continuous layers of insulating material each have insulating properties equivalent to at least 0.5 inch of polystyrene foam.

5. The method of claim 1 , wherein the first and second continuous layers of insulating material each have insulating properties equivalent to at least 1 inch of polystyrene foam.

6. The method of claim 1 , wherein the first and second continuous layers of insulating material each have insulating properties equivalent to at least 2 inches of polystyrene foam.

7. The concrete form of claim 6 , wherein the removable third layer of insulating material has insulating properties equivalent to at least 2 inch of polystyrene foam.

8. The method of claim 1 , wherein the first and second continuous layers of insulating material each comprises a layer of refractory insulating material in an adhesive.

9. The method of claim 1 , wherein the first and second continuous layers of insulating material each comprises a layer of ceramic fibers in an adhesive.

10. The method of claim 9 , wherein the adhesive is polyurethane or epoxy.

11. The method of claim 1 , wherein the first and second continuous layers of insulating material each comprises Wollastonite in an adhesive.

12. The method of claim 1 , wherein the first and second continuous layers of insulating material each comprises closed cell polymeric foam.

13. The method of claim 1 , wherein the first and second continuous layers of insulating material each comprise rigid insulating polymeric foam.

14. The method of claim 1 , wherein the first and second continuous layers of insulating material each comprise a polymeric foam of polyvinyl chloride, urethane, polyurethane, polyisocyanurate, phenol, polyethylene, polyimide or expanded polystyrene.

15. The method of claim 1 , wherein the removable third layer of insulating material has insulating properties equivalent to at least 1 inch of polystyrene foam.

16. The method of claim 15 , wherein the removable third layer of insulating material comprises a polymeric foam of polyvinyl chloride, urethane, polyurethane, polyisocyanurate, phenol, polyethylene, polyimide or expanded polystyrene.

17. The method of claim 1 , wherein the removable third layer of insulating material has insulating properties equivalent to at least 2 inch of polystyrene foam.

18. The method of claim 17 , wherein the removable third layer of insulating material comprises a polymeric foam of polyvinyl chloride, urethane, polyurethane, polyisocyanurate, phenol, polyethylene, polyimide or expanded polystyrene.

19. The method of claim 1 , wherein the removable third layer of insulating material comprises a polymeric foam of polyvinyl chloride, urethane, polyurethane, polyisocyanurate, phenol, polyethylene, polyimide or expanded polystyrene.
