Abstract: The present invention contemplates a reinforced concrete beam comprising a longitudinally extending concrete beam including a plurality of I-beam receptacles spaced apart along the length thereof and wherein each of the I-beam receptacles has a depth and a width to accommodate an end of an I-beam having an upper and lower metal flange of about equal width and a central metal web connecting the flanges, and in the building a hard rubberlike elastomer spacer is disposed between the I-beam receptacles and an end of an I-beam. The beams further include one to three longitudinally extending metal rods disposed underneath the I-beam receptacles and surrounded by concrete.

Abstract: A device 10 for forming concrete includes a first form 12 dimensioned to surround substantially one-half of a predetermined object 13, such as a vertical column 13, from a preselected distance; a second form 14 dimensioned to surround substantially one-half of the column 13 from substantially the same preselected distance; joining members 16 for detachably joining end portions 18 of the first and second forms 12 and 14; and securing members 20 for removably securing the first and second forms 12 and 14 to the column 13 after joining together the end portions 18 of the first and second forms 12 and 14 about the column 13. The joined first and second forms 12 and 14 remain substantially stationary as concrete is poured into the device 10; whereupon, the concrete ultimately hardens and the device is quickly removed and re-positioned about another vertical column 13.

Abstract: A stay-in-place concrete footings form is used for forming a concrete footing between a spaced-apart pair of the stay-in-place concrete footings forms. Each concrete footing form is elongate and has a cavity inside the form. Each form has a pair of elongate sides wherein openings are formed in the elongate sides to permit water to flow into the cavity. Each form has a dovetail pin or dovetail slot formed along the lengthwise extent of both sides of the form. The dovetails permit clamps, having a mating dovetail slot or dovetail pin, to be clamped to the form for anchoring the form to the ground with a stake carried by the clamps.

Abstract: A system of building concrete homes and apartment buildings. The system creates a structure that is well insulated and that is very practical and economical to build. The system uses standard components such as wall ties, concrete forms, rigid foam insulation, and concrete, all of which are readily available in the market today. The system creates a building that is insulated and thermally broken at its structural connections such that use in temperate and colder climates is possible. Presently concrete construction finds only limited use for the construction of single family and multi-family housing. The system is economical to construct when compared to wood frame housing.

Abstract: A concrete floor system used in a building structure and a method of making floor components used with the floor system. The concrete floor system, if installed on grade, provides for expansion and contraction due to expansive soils and eliminates cracks, which heretofore occurred in poured concrete slab floors. The concrete floor system includes a plurality of parallel concrete beams. The beams can be made up of hollow concrete blocks for reduced weight and receiving a tension cable therethrough. Also, the beams can be either solid pre-cast beams, solid pre-cast, pre-tension beams or solid pre-cast, post-tension beams. Opposite ends of the cable are held on end plates inside recessed ends of each hollow beam. The ends of the beams are adapted for mounting next to the inside of the sides of a building foundation wall. The beams can be in a range of 5 to 20 feet and greater in length depending on the dimensions of the concrete floor.

Abstract: Disclosed are a height-adjustable concrete mold supporting system and a method for constructing concrete floors and concrete walls, by which a concrete building can be easily and precisely constructed with enhanced cost-effectiveness.

The first and the second screw shafts are movably inserted into first and second height adjusting tubes. A top mounting board is supported by the first and the second height adjusting tubes. The first and the second height adjusting tubes are fixed to the first and the second screw shafts so as to determine an adjusted space between the bracket and the mounting board.

Abstract: A concrete form panel clamp includes a threaded rod having a first pin mounted at a first end generally perpendicular to the rod. A second pin spaced away from and generally parallel to the rod is slidably mounted on the rod. A nut threaded onto the rod selectively forces the second pin toward the first pin.

Abstract: A formwork frame for supporting decking and a fresh concrete floor on the decking includes a horizontal beam whose upper surface contacts the concrete and a vertical shaft that supports the beam. The beam is formed in three separable extruded aluminium sections, a central section mounted on the shaft and a pair of outer sections. The central beam section has opposing ends mitred to converge in a downward direction, and each outer beam has an end mitered to meet one end of the central beam section. The beam has a horizontal channel in each of its sides, and a pair of horizontal ledges close the channels from below. A pair of extruded aluminum bridging members fit closely into the channels and are effectively reinforced by the beam sections to resist bending moments. Pins extend horizontally through the bridging members and the outer beam sections to secure the bridging members to the beam. The pins are not subjected shear forces or bending moments.

Abstract: A cradle for an adjustable brace used for supporting an elevated concrete form floor between support beams during the curing of the concrete is provided. The cradle is adapted to receive the upper portion of two legs such that the legs can pivot towards and away from each other in a single plane, to enable the lower portion of the legs to be placed for support against opposing support beams positioned at varying distances from each other. The cradle is also adapted to receive and support a shoring member for suppoting the concrete form floor. The cradle may be adjustable for supporting shoring members at varying heights.

Abstract: A hanger and bracket attached to the hanger for supporting formwork for steel and concrete during the curing stage of a bridge deck overhang is described. A hanger attached to the beam of the bridge supports a connector carrying the bracket. The connector is maintained in a substantially vertical position. The bracket is adjustable in both horizontal angle and in grade because of pivotally attached horizontal members, an adjustable compression leg, and connector means. Once the cement is set the bracket may be recovered for reuse.

Abstract: A clamping device of this invention is constructed of bases on which molds are slidably moved, regulating portions each provided above the corresponding base and having a clamping surface which is inclined relative to the base, shifting means provided beside the bases and for shifting each mold placed on the base in a direction to which the space between the base and the clamping surface progressively narrows and a spacer fixedly mounted on the upper surface of the mold, the upper surface of which being in the form of an arc in a direction to which the mold is moved. In use, each of the molds placed on the base is moved by the shifting means. The mold is then sandwiched between the base and the clamping surface and clamped to a wedge configuration.

Abstract: A form for supporting from below a layer of concrete during pouring and hardening has several square or rectangular panels having neighboring marginal portions with downwardly extending reinforcing skirts which are separably connected to each other by bolts. The panels rest on props which must be removed prior to separation of the panels from each other. In order to dismantle the form in the space below the hardened concrete layer, the props for one of the panels are removed and a dismantling device is separably coupled to a panel which is adjacent to the one panel. The dismantling device has a socket below the skirt of the one panel and the one panel is thereupon detached from the panel which carries the dismantling device so that the skirt of the one panel descends into the socket. The one panel is then pivoted with reference to the socketed part of the dismantling device so that its upper side moves away from the underside of the concrete layer.
