20110047915 | Clamp for fastening concrete rebar intersections - A structure for clamping two rods mutually transverse to one another is described. An upwardly open seating surface has a longitudinal direction for rotationally vertically receiving a first rod in the longitudinal direction. A pair of side opening rod retainers are supported above and on opposite sides of the upwardly open longitudinal seating surface. The side openings of the retainers open in opposite directions for rotationally laterally receiving opposite sides of a second rod along a direction transverse to the longitudinal direction. The retainers include top portions spaced from the lower seating surface a distance effective to cause a rod rotationally laterally received in the side openings to exert a compressive force against a rod rotationally vertically received on the lower seating surface, thereby clamping the rods mutually transversely to each other. The clamping structure may be rotated into the intersection to vertically receive the first rod in the longitudinal seat and to laterally receive opposite sides of the second rod under the top retainer portions to press the second rod forcibly against the first rod in the longitudinal seat. Using the clamping structure in the form of a chair, a mat is formed using the chairs to transversely clamp a plurality of first and second rods at right angles, concrete is poured on the mat supported over a pour surface by the chairs, and a reinforced concrete slab is formed in which the mat is positioned at a predetermined position internally in the slab. | 03-03-2011 |

20130008114 | METHOD AND DEVICE FOR STRENGTHENING AND LIGHTENING FLOOR AND ROOF FRAMING - Method and device for strengthening and lightening floor and roof framing, where the beams and the compression slab are firmly integrated, making it possible to easily recover the moulds or blocks lightening the framing. The method uses several devices, prefabricated beams, moulds, mesh, concrete laid on site and where necessary reinforcing rods. The devices comprise essentially: a section, two bolts and a pin. The section will be tensile-stress resistant and folded into a “U” shape to match the beams. The method involves affixing the device, wrapped transversally around the beam. Likewise, and several devices can be affixed along each beam. The beams are then placed on their walls or girders, parallel and separated depending on the moulds, then the moulds are seated in the protruding segments of the bolts of the device until the spans are covered, affixing reinforcing rods in the sides of the device where necessary. The mesh is then laid by attaching it to the ends of the devices. The concrete is then poured until the compression slab and the channels above the beams are filled. Once set, the bolts are removed to recover the moulds from below. | 01-10-2013 |
