Definitions

  • This invention relates to a device and method suitable [30] Foreign Application Priority Data for temporarily supporting formwork from piles whilst concrete lS cast into the formwork to form a platform Oct. 15, 1971 Great Britain 48175/71 or the like carried by the piles
  • Each device includes a clamp member detachably securable around a pile and [52] [1.8. Cl .1 252/988, 2294/;1226,92486/i96, having horizontal flanges on which a carriage is s
  • the invention is particularly, but not exclusively, directed to devices, methods and systems, for temporarily supporting a structure, such as form work or shuttering, from piles or other supports whilst concrete or the like, which is ultimately to form a platform or the like carried by the piles, is cast in the formwork, the formwork being removed after the concrete has hardened sufficiently to become self-supporting.
  • Such support devices have comprised metal hangers suspended from the top of the piles which, after casting, are partially embedded in the concrete. After removal of the formwork, the portions of the hangers projecting from the concrete which previously engaged the formwork, were preferably removed, and the remaining portions of the hangers were concreted over so as to become totally embedded in the concrete.
  • Such a system possesses the disadvantages that the remaining portions of the hangers, even if totally embedded, tend to corrode and cause consequential damage to the adjacent concrete, particularly in marine or other adverse environments.
  • the present invention consists in a support device for supporting a structure from a pile or like elongate support, which device comprises a clamp member adapted to be detachably secured around the support and to frictionally grip the support, the clamp member including at least one structure-supporting element.
  • the invention consists in a method for temporarily-supporting a structure from a plurality of piles or like elongate supports, which comprises clamping a plurality of support devices as above defined to the supports, locating and supporting the structure on said clamping members, and subsequently removing said structure and clamping members.
  • the said structure When applied to the construction, in situ, of a platform or the like from concrete or other castable material, the said structure may comprise formwork or shuttering, in which event the method will include assembling the formwork on the positioned support devices, casting the castable material in the formwork against or around the supports, allowing the castable material to harden, and subsequently removing the formwork and support devices.
  • FIGS. 4 and 5 are, respectively, plan and side views of the jack and roller carriage shown in FIGS. 1 to 3, with the jack and roller omitted.
  • the support device basically includes a clamp member comprising two collar parts 1, 2 formed from a suitable material, for example fabricated from steel plate, to the configuration shown in FIGS. 1 to 3.
  • the two collar parts I and 2 define a generally circular opening (FIG. I) for receiving a pile 3, and are secured together around the pile 3 by means of bolts 4 (FIGS. 2 and 3) to positively frictionally clamp the clamp member to the pile 3.
  • the collar parts 1 and 2 each include a pair of lateral arms 5 having horizontally extending flanges 6.
  • the flanges 6 of one or both pairs of arms 5 may directly support shuttering, formwork or other structures (not shown), or may indirectly support the latter via one or more support arrangements, one of which is indicated generally at 7.
  • This arrangement comprises a fabricated carriage which is slidable along the flanges 6, and has sides 7b formed with slots 7a in which is journalled a roller 8.
  • An internally threaded jack nut 9 is secured to the base 7c of the carriage, and an adjustable jack screw 10 extends through the jack nut and base. Adjacent its upper end, the jack screw 10 is provided with a raised threaded zone 10a which cooperates with the jack nut 9.
  • the jack screw 10 is provided at its upper end, with a thrust pad or plate 10b, supported from the jack screw 10 via a ball and socket joint 10c which permits universal adjustment of the inclination of the plate 10b relative to the jack screw.
  • the jack screw 10 is terminated by a square boss 10d by which the jack screw may be coupled to a suitable device (not shown) for rotating the jack screw and thereby adjusting the height of the plate 10b.
  • an angle bracket 12 secured to the carriage and extending below one of the flanges 6 serves as a stop to limit movement of the support arrangement 7 from left to right in FIG. 3, and also serves to prevent the arrangement 7 from being accidentally separated upwardly from the flanges 6.
  • the collar parts and carriage may be fabricated by welding from mild steel plate ranging between and V2 inch thick, the total weight of the collar parts I and 2 and one support arrangement 7 being between 4 and 5cwt.
  • the overall span of the collar parts 1 and 2 i.e., the distance between opposite outer ends of the flanges 6 as viewed in FIG. 1, may be approximately ft, and the support arrangement 7 may be displaceable over a distance of approximately 1 ft. along the flanges 6.
  • the maximum lift of the jack screw may be approximately 4 inches.
  • a plurality of support devices may be employed in the construction of installations, such as marine quays or jetties, in which large reinforced concrete platforms or the like, carried on the upper ends of piles, are to be cast in situ.
  • the concrete is cast into the formwork, around and embedding the tops of the piles.
  • the jack screws 10 are rotated to lower the thrust plates 10b to lower the beams onto the rollers 8.
  • the beams, if desired with the formwork thereon, are then rolled out from beneath the cast concrete platform on the rollers 8, preferably in a direction from left to right in FIG. 3, so that any resultant displacement of the support arrangement 7 in the same direction is limited by the angle bracket 12, and not by engagement of the jack screw 10 with the arm 5 of the collar part 1, thus avoiding lateral loading of the jack screw.
  • the support arrangements are then removal laterally from the flanges 6 oftheir associated collars, and the parts 1 and 2 unbolted and removed.
  • the support devices employed for carrying the formwork are easily securable to the piles, may be readily clamped at the required elevation, and are frictionally positively clamped in place, without requiring special locating projections on, or recesses in, the piles, and without damaging the piles.
  • the support devices when removed, do not leave any remnants partially or wholly embedded in the cast platform which could corrode and damage the platform. Due to the provision of the support arrangement 7, the formwork maybe readily assembled, accurately adjusted without the necessity of accurately positioning the collars, and removed. Furthermore, the support devices are uncomplicated, robust, and capable of being used time and again.
  • the jacks and/or rollers of the support arrangements 7 may be omitted, or the rollers may be replaced by other means to facilitate longitudinal displacement of the beams relative to the support devices during assembly and/or removal of the formwork, and the jacks may be replaced by other means to enable at least lowering of the beams and preferably also raising of the beams, for example hydraulic, sand or diaphragm jacks.
  • One or more support arrangements 7 or equivalent may be located on one pair, or both pairs, of opposed flanges 6 of each support device. Alternatively, the support arrangements may be omitted, in which event, the beams will rest directly on the flanges 6, or their equivalent.
  • the use of the support devices is not restricted thereto, and they may be employed permanently or temporarily to support other structures from piles or the like, for example gangways, cat-walks, etc.
  • the support devices may be used in conjunction with non-circular section piles, such as oval, rectangular, or polygonal section piles, in which event, the collar parts 1 and 2 will preferably be designed to define a correspondingly shaped pile-receiving opening.
  • the internal surfaces of the collar parts which, in use, cooperate with the surface of the pile, may be smooth, or serrated, toothed or otherwise roughened, or tapered, to enhance the clamping action of the device.
  • the collar may comprise more than two parts, and the parts may be secured together by means other than bolts, and may be hingedly interconnected instead of being separate.
  • a temporary support device for temporarily supporting a structure from an elongate support comprising a releasable clamp member adapted to be detachably secured around the support and to frictionally grip the support, the clamp member comprising a two-part collar, the two collar parts being securable together, after location of the collar parts around the support, to immovably clamp the clamp member to the support, the collar parts including generally arcuate central portions defining a generally tubular support-receiving opening within which the support is clamped when the collar parts are secured together, each collar part further including structure-supporting elements comprising a pair of flanges extending from opposite sides of the associated central portion, the flanges of one collar part being disposed parallel to, but spaced from, the flanges of the other part, when the collar parts are sethe carriage and collar parts are fabricated from sheet metal, the jack comprising a jack nut integral with the carriage and a jack screw rotatably cooperating with the jack nut, and extending downwardly
