The second part is detachably mounted on the first part and includes a base plate and an anchoring element which can be affixed to or releasably secured to the base plate.

Abstract: Composite building module having a rigid foam core encased in an enclosed shell made of fiber reinforced cement and an anchor device for attaching the module to a supporting structure. The anchor has an anchoring portion extending through the shell and an interlocking portion attached to the anchoring portion and extending into the foam core. The foam core is foamed within the enclosed shell filling the interior thereof and enveloping at least the interlocking portion of the anchor device.

Abstract: A metallurgical furnace for the high temperature heating of heavy metal objects for subsequent operation, such as rolling or forging, has a work support for the pieces being heated comprised of water-cooled tubes and supports enclosed with sectional heat insulating tile enclosing the tubes where the sections of tile are immovably secured to the tubes by fasteners each having a tubular shank extending from a flanged head portion embedded in the refractory radially inward to the inner surface of the tile where it is welded to the exterior of the water-cooled tube to prevent relative movement between the tile and the tube under the heavy impacts to which the support is subjected and to more effectively cool the refractory tile immediately adjacent the fasteners.

Abstract: Fixation of an artefact to a support means, such as of cement panels as exterior cladding for buildings, a reinforced plastics compressor blade or a ceramic turbine blade to a rotary hub member, or of an electric insulator of longitudinally reinforced plastics material to a transmission tower, the artefact being subject at least at times to longitudinal shear stresses, is effected through duplex fibre means, whereby the stresses are transferred to the support means through the duplex fibre means.

Abstract: A building structure wall, in particular a facade construction, is made of plate-like construction elements arranged beside and above one another and secured to elongate members, and recesses being provided in the construction elements, and closing elements surrounding the elongate members are inserted in the recesses and boltable with at least one of the plate-like construction elements.

Abstract: A prefabricated panel utilizing a lightweight metal frame fabricated from metal members having a web and two substantially parallel flanges which extend in opposite directions from the edges of the web. The facing is joined to said frame by means of joining means which extend from the back of said facing through holes in the flanges of the members of the frame.

Abstract: A device for mounting panels of fibrous refractory material against the inner surface of the wall of an industrial furnace, comprising a plug of refractory material in the form of a bolt with a square head and a non-threaded cylindrical shank provided with a plurality of circular ribs arranged in planes perpendicular to the axis of the plug, the panels to be attached thereby having spaced-apart apertures of dimensions intermediate those of the head and of the ribs on the shank, and the wall of the furnace having corresponding cavities filled with a sealing material and for receiving the shank of the plug.

Abstract: A wall having an outer structural component of masonry units which are provided with dovetail slots in their inner faces. A fixing device is provided which has a tongue at one end of a screw threaded rod and an adjustable cap at the other. The tongue is inserted and fixed into the dovetail slot and the cap adjusted by screwing on the rod. Caps of the various fixing devices are aligned in a vertical plane and an inner skin of plaster board or the like secured by screwing to the aligned caps. Transfer of moisture from the porous masonry wall to the inner skin is prevented by providing sufficient screw threading on the rod to allow a number of turns of the thread to remain exposed when the cap is screwed to its innermost position.

Abstract: A method and apparatus for preparing slabs of material such as granite for transportation and erection. The apparatus includes a cutting bit and means actuating the bit into the face of the slab so as to form an arcuate slot, widest at the bottom, centered outside the slab. The slot may be dove-tail or inverted-T in configuration, to receive the heads of conventional fasteners, by means of which the slab may be hoisted or transported, as well as being finally secured in its ultimate facing or other location thereby.

Abstract: Coupling structure for artificial stone parts such as concrete plates etc., have an anchoring member partially embedded in the stone with a head projecting therefrom and releasably inserted in a coupling member of C-shaped cross-section e.g. for suspension but permitting limited turning on an axis longitudinal to the C-groove of the coupling member, so that lateral forces are reacted into the anchoring member. Additional features include support flanges on the anchoring member; bent off portions of the anchoring member with additional members; wire loops for improving anchoring; and special bayonet-like insertion and locking of the head in a particular type coupling member.

Abstract: Prefabricated insulating blocks are formed from ceramic fiber blankets folded into plural folds, with adjacent layers being needled together to intermingle the fibers of adjacent layers to form composite blocks. The blankets are mounted to attachment channels by support beams, mounted within folds in the blankets, and the folds of the blanket surround and enclose the support beams to protect them from heat and corrosive gases in the furnace.

Abstract: A masonry wall comprising a plurality of laminated building blocks, wherein each block has an insulation layer laminated to one face. The length and breadth of the insulation layer exceed the corresponding dimensions of the block by the width of the mortar used to bond the blocks in place and the insulation layer is offset from two adjacent edges of the block. This structure is combined with critical dimensions relative to standard modular bricks to produce optimally large blocks for minimum labor and construction costs.

Abstract: A facade wall plate is provided on its back face with a steel stranded-wire loop into which is hooked the lower end of a hanger whose upper end is hooked over a similar such loop projecting from the front face of a support wall. The hanger may be a turnbuckle wherein rotation of a central sleeve shortens the distance between the hanger ends for positioning the facade, or at least one end of the hanger may be slidable along the hanger by a rotatable nut for varying the hanger length. Each such loop is formed by a continuous loop of cable imbedded in the respective facade plate or wall and looped therein around the reinforcement thereof.

Abstract: A new and improved apparatus and method for lining walls of furnaces, and other high temperature equipment, wherein insulating blankets are folded and supports are mounted in the folds thereof for mounting to the furnace wall to insulate the furnace. In some applications, the lining apparatus is formed into preformed insulation blocks for installation as insulating linings.
