Definitions

  • the present invention relates to a sandwich-slab construction, especially for the prefabricated and semifabricated erection of concrete structures, to a connector or anchor for the members of a sandwich-slab structure and to a system for assembling a sandwich slab; more particularly, the invention relates to an improved assembly of the type wherein a pair of concrete plates are interconnected in spaced relationship and sandwich an insulating layer between them.
  • a composite or laminar structure for construction purposes will comprise a number of layers tied together in a more or less rigid manner, each layer contributing some characteristic to the overall properties of the plate.
  • the sandwich or laminar structure may comprise one or more facing members defining an outer surface of the structure to provide an aesthetic appearance or a desired texture, one or more load-supporting members adapted to support the laminar structure or a suitable carrier or frame or adapted to support another structure on the plate, one or more insulating members or layers designed to resist heat transfer between the inner and outer surfaces of the slab, and one or more core or filler members adapted to provide the desired bulk. It will be evident that one or more of these members can be eliminated, depending upon the physical or aesthetic properties desired or additional members, e.g., sound-insulating layers, may be provided if certain qualities are to be enhanced.
  • a sandwich slab of concrete which may be used for walls, partitions, load-supporting members, floors, ceilings and roofs of buildings, generally comprises a pair of reinforced-contrete plates'flanking a layer of thermal insulation and sound insulation and held together by anchors which traverse the insulating layer and tie the concrete plates together.
  • the concrete plates and the insulating layer are coextensive or substantially coextensive, i.e., have geometrically congruent outlines and are usually rectangular.
  • the sandwich slab may be fabricated at a factory or plant remote from the construction site, may be transported thereto by any convenient conveyers, and may be erected at the site with cranes or the like.
  • slabs are generally anchored by bolts, pins, studs, welding or adhesives to a support frame which may be cast from concrete in situ or which may be erected from steel or the like.
  • the concrete plates constituting the sandwich slab are reinforced, as noted earlier, and may be provided with a lattice-work of reinforcing bars, rod or wire, previously tied, welded or otherwise joined to form a reinforcing mat.
  • the reinforcing members are generally constituted of steel.
  • the insulating layer may, of course, be of any of the types accepted in concrete-slab construction and is preferably a relatively rigid plate or sheet.
  • a foamed synthetic resin e.g., cellular polystyrene, is typical for this layer.
  • the tubules or sleeves are tube or pipe sections of a regular cross-section, Le, a cross-section corresponding to that of a conic section or a regular polygon, and preferably which is constant over the entire length of the anchor although it has been found to be advantageous in certain circumstances to provide a constant convergence to the anchor.
  • the anchor sleeve is conical, the conicity assisting in anchoring the concrete plates together.
  • the means at each end of the sleeve include arrangements engageable with the reinforcing members of the respective concrete plates and it is preferred to provide lattice-like reinforcements for the latter.
  • the anchor is dimensioned to extend into an interstice of the reinforcing lattice of each concrete slab and to be provided with laterally outwardly extending formations engageable behind the reinforcing rod or members of the latticework.
  • the anchor sleeves are formed with rows of holes or perforations proximal to their ends while the aforementioned formations receive bars or rods traversing these holes and projecting laterally beyond each anchor to overhang or underlie a reinforcing rod or bar of the lattice.
  • two longitudinally spaced rows of such holes are provided and at least one rod is fitted into each row of holes so that the transverse rods engage on opposite sides of the reinforcing mats.
  • Each row of holes will generally include a number of pairs of diametrically opposite perforations which are aligned to permit the transverse rod to extend through them.
  • the means for locking the sleeves within the concrete plates can include tabs or lugs which may be bent outwardly to project laterally.
  • Still another object of the invention resides in the insertion into the sleeve of a plug of insulating material to prevent thermal losses through these anchors.
  • the plug may be punched from the insulating plate in the formation of the opening through which the: anchor is to extend and the punching may be effected by driving the sleeve into the insulating layer at the time the sleeve is mounted, the plug of insulating material remaining within this sleeve.
  • the anchor is constituted of metal, preferably steel, and may be cut from a pipe or tube or built up from steel plates or bent from sheet metal, other materials may be used according to the physical properties desired.
  • the system of the present invention provides a large effective diameter linking the two concrete plates and hence involves a force-transmission which is distributed over a large area by virtue of the large diameter and cross-section of the anchor.
  • the steel sleeves in the concrete have substantially coincident coefficients of thermal expansion and the relatively thin steel sleeve is generally at the same temperature as the concrete so that thermal stresses are minimized. Since the sleeves act as force-transmitting columns, shear stresses of the slab parallel to the concrete plates have little effect and, since the sleeve always extend perpendicular to the concrete plates, the sleeves are tortionally rigid and can take up the necessary stresses when the sandwich slab is rotated in its plane during mounting. It has already been observed that the slabs can be used to form facades, roofs and load-supporting walkways and floors.
  • FIG. 1 is a cross-section perpendicular to the plane of sandwich slab according to the invention, illustrating the anchor assembly in elevation;
  • FIG. 2 is a view taken in the direction of arrow II and partly broken away;
  • FIG. 3 is a cross-section taken along the line Ill III of FIG. 1;
  • FIGS. 4 6 are perspective views illustrating other anchor sleeves according to the invention.
  • FIG. 7 is a perspective view showing another assembly using an anchor sleeve according to the invention.
  • FIG. 8 is a plan view showing the structural member of the present invention.
  • the sandwich slab construction of the present invention may, as shown diagrammatically in FIG. 8, comprise a rear concrete slab I03 having a mat 106 of reinforcing rod embedded therein and of generally rectangular configuration.
  • the concrete plate 103 is coextensive with a slab or plate of cellular synthetic resin as represented at 102, this insulating layer of foamed polystyrene, for example, being overlain by the upper plate 101 of concrete.
  • the plates are interconnected by anchor sleeves generally represented at 104 at spaced locations, the anchor sleeve 104 being constituted as described in connection with FIGS. 1 7.
  • the reinforced concrete plate 1, the insulating layer 2 of foamed synthetic resin, and the rear reinforced plate 3 constitute a sandwich slab.
  • the concrete plates 1 and 3 are anchored together by tubules or sleeves 4 provided at respective extremities with means for locking the sleeve to the respective concrete plates.
  • the lower concrete plate 3 is provided with a lattice work or mat 6' of reinforcing rod, the rod running parallel to the plane of the paper being represented at while the rods 6b run perpendicular tothe plane of the paper.
  • the rods 60' and 6b therefore, define a lattice work in an interstice of which the sleeve 4 is seated.
  • the mat has an effective thickness V (FIG. 1).
  • the means 5 at each end of the sleeve 4 may include rows 50 and Sb of perforations which are angularly staggered and are spaced axially by a distance U V, each hole being paired with a diametrically opposite hole so that rods 7 may be passed through the holes and project laterally to engage the rods of the mats 6.
  • the rods 7 may be lengths of reinforcing rod and project to a distance W X where X is the spacing of a rod of the mat from the tube 4. It has been found to the advantageous to have the projecting portions of the rods 7 approximate the diameter D of the tube. In practice, 0.5 D S W 5 1.5 D.
  • the rods 7 have diameters D" which are slightly less than the diameters d of the holes 50 and 5b.
  • the sleeve 4 may have a thickness S (FIG. 3) which is less than D and a minor fraction of the diameter D of the tube, this diameter corresponding approximately to the thickness T or T of the concrete plates.
  • insulating layer 2 will have a thickness R ranging between 0.3Tand 1.5 T.
  • the interior of the sleeve 4 is provided with a plug 8 of the foamed synthetic resin constituting the layer 2 and punched out when the tube 4 is driven into the insulat ing layer. To facilitate the punching of this plug, an edge of the tube can be chamfered.
  • FIGS. 4-7 other tube structures have been illustrated and it will be understood that, in each case, the structure may be used interchangeably with the tube 4 and in the system illustrated in FIG. 8.
  • the cylindrical tube 204 is provided with formations generally represented at 205 at opposite extremities for anchoring to the concrete plates. These formations include the ports 205a and 205b as described in connection with tube 4, and crenelated extremities having tongues 2050 which may be bent outwardly as shown in dot-dash lines to engage the concrete or, as described in connection with FIG. 7, to lodge behind the mats.
  • the tube 304 has a rectangular cross-section (square) and the rows 305a and 3051) of holes permit two or more rods 307 to extend in each direction as part of the anchor means represented generally at 305.
  • the tube 404 illustrated in FIG. 6 is of conical configuration and likewise has means 405 in the form of rows of holes for anchoring the tube in the concrete slab.
