Abstract
A metal concrete form panel having a face sheet secured to a perimeter flange that includes side rails and end rails. One or more tie ribs extend between the end rails. A bolt block is secured in each corner to the perimeter flange where the side rails meet the end rails. A bar is located spaced inside each side rail and extended between and secured to each of the pair of opposing bolt blocks of the associated end rail and also secured to each intervening tie rib and to the face sheet.
Claims15
A modular metal panel for forming concrete structures, the panel comprising:
- (a) a face sheet secured to a perimeter flange having side rails and end rails;
- (b) two bolt blocks secured to the face sheet, wherein each of the two bolt blocks is secured to the perimeter flange in opposing corners of the form panel where the side rails meet the end rails;
- and
- (c) a strengthening bar disposed inside each side rail at a distance from each side rail and extended between and secured at a first end to a first of the two bolt blocks and at a second end to a second of the two bolt blocks, wherein the strengthening bar is secured to the face sheet.
A modular form panel for concrete construction, the form panel comprising:
- (a) a face sheet;
- (b) a flange disposed around a perimeter of the face sheet, the flange comprising first and second opposing side rails and first and second opposing end rails;
- (c) four bolt blocks attached to the face sheet, the first and second side rails, and the first and second end rails, wherein each of the four bolt blocks is disposed in a separate corner of the face sheet;
- (d) at least one rib attached at a first end to the first side rail and at a second end to the second side rail;
- (e) a first reinforcement bar disposed between and parallel with the first and second side rails and attached at a first end to a first of the four bolt blocks and at a second end to a second of the four bolt blocks;
- and
- (f) a second reinforcement bar disposed between and parallel with the first and second side rails and attached at a first end to a third of the four bolt blocks and at a second end to a fourth of the four bolt blocks.
A modular form panel for concrete construction, the form panel comprising:
- (a) a face sheet;
- (b) a flange disposed around a perimeter of the face sheet, the flange comprising first and second opposing side rails and first and second opposing end rails;
- (c) four bolt blocks attached to the face sheet, the first and second side rails, and the first and second end rails, wherein each of the four bolt blocks is disposed in a separate corner of the face sheet and comprises at least one opening configured to receive a bolt;
- (d) at least one rib attached at a first end to the first side rail and at a second end to the second side rail;
- (e) a first reinforcement bar attached at a first end to a first of the four bolt blocks and at a second end to a second of the four bolt blocks;
- and
- (f) a second reinforcement bar attached at a first end to a third of the four bolt blocks and at a second end to a fourth of the four bolt blocks.
