Abstract: An adjustable screed support for supporting one end of a screed during screeding of cement on a wall generally comprises a support bracket for attachment to the wall support structure including a stand-off portion extending outward, away from the wall support structure; and an elongate beam which is adjustably attached to the support bracket stand-off such that the distance of the top side of the beam from the wall support structure and the angle of the line of the beam the wall support structure are variable. The beam top side in side view is a straight line. The beam has holes side to side through its web portion and the support bracket stand-off portion has conguent holes. Cement from each side of the screed support flows through the holes and bonds to the cement on the other side.

Abstract: A specific feature of the present invention resides in that it is provided with a device for a cyclic advance of the tape from a reel, made in the form of plates different in size and arranged in succession on the body and clamp, each of said plates is provided with a slot for passing the tape, the slots being arranged on the shorter plate at free ends thereof and on the longer plates, level with the slots arranged on the shorter plates.

Abstract: A metallic ceiling lining consists of a supporting grid of longitudinal struts and transverse struts and cassettes arranged in the grid compartments. The longitudinal struts and transverse struts have their lower ends. The cassettes rest in a gastight manner on the projections and the longitudinal struts are designed as essentially rectangular hollow profiles. To permit the attachment of ancillary devices such as lights or partitions witout impairing the gastightness of the ceiling lining, the hollow profile is designed as a closed duct and the longitudinal strut also has a region of tubular cross-section for mounting suspended elements. The invention is applicable to all types of gastight ceiling linings.

Abstract: A barrier for preventing pigeons from landing on a balcony rail comprising a pair of support brackets adapted for flush mounting to opposite ends of the balcony rail, and a plurality of monofilament wires secured between the pair of support brackets.

Abstract: An improved flashing unit for use in weatherproofing a roof penetration including complimentary mating half portions of generally regid, high-strength sheet material, each half portion comprising a base plate, a generally semi-cylindrical stack portion attached to and extending upwardly from the base plate, each base plate having an upwardly directed generally semi-cylindrical flanged edge disposed within the lower end of each semi-cylindrical stack portion, a longitudinal edge portion of each stack portion forming an elongated continuous channel for receipt of a corresponding smooth longitudinal edge of the opposite stack portion for snap-fit frictional retention of the two stack portions when mated with the edge portions of the base plates in abutment, lap plates attached to abutting edge portions of the base plates to be received in lapping relation with an abutting side edge portion of the opposing base plate, and a generally cylindrical counterflashing, or cap, for surrounding a roof penetration and rece

Abstract: An improved building panel. The panel includes a pair of identically formed facing sheets arranged with adjacent edges extending parallel and spaced apart to one another and an insulating core between the facing sheets to minimize the transfer of heat from one facing sheet to the other through the space therebetween. The panel further includes a channel member assembly for receiving the adjacent edges of the sheets to form a joint between the sheets. The channel member assembly includes at least one pair of opposing legs extending parallel and spaced apart to one another for interconnecting the sheets with one another and a web portion extending between interconnecting the opposing legs. The web portion includes an insulating bridge member positioned between the opposing legs adjoining the pair of facing sheets to minimize the transfer of heat from one facing sheet to the other through the web portion and defining a noncontinuous space.

Abstract: A reroofing system and method for weatherproofing the metal panels which are attached to an existing roof deck by series of fasteners. A tape laminate formed of butyl rubber and unvulcanized EPDM is applied over the series of fasteners and over the seams formed by adjacent and overlapping panels to provide a weatherproof seal therefor. The butyl rubber has sufficient natural tackiness to secure the EPDM to its top surface and to secure the bottom surface of the tape to the metal panels. The tape laminate has an elongation of approximately 600% and thus is unaffected by panel and building movements. A coating of an acrylic paint may be applied over the tape laminate and remaining surfaces of the roof panels to increase the weatherproofing effectiveness thereof and to provide an aesthetically pleasing appearance.

Abstract: A system for controlling a flexible roof assembly of the type used to cover large structures determines the actual variable height of one or more sections of the roof assembly with respect to a fixed reference point and regulates the apparatus for elevating the roof assembly to accurately control the position of the roof assembly. The system includes a signal generator for generating a signal corresponding to the actual height to indicate a change in height of the roof assembly. The system may also include an apparatus for detecting the presence of either ice or snow in an area of an outer surface of the roof assembly. The detecting apparatus includes a collecting device that is oriented to collect snow and ice that is accumulating and a sensor unit directed toward the collecting device to detect an accumulation of ice or snow that reaches a specified depth.

Abstract: An abandonment plug assembly for limiting heat and fire passage through an opening formed through a floor, comprises a cover for disposition atop the floor and configured to extend beyond the opening and engage the floor, first and second cup members dependant from the cover and mutually displaceable toward one another to force a substance disposed therebetween into contiguity with the sidewall bounding the opening, an actuator for effecting the displacement of the first and second cup members and intumescent discs depending from the second cup member.

Abstract: A brick or construction element comprised of cement or synthetic sand and/or gravel of the kind for erecting high embankments or earthworks has a shield-type support with a flat front wall to which are connected lateral wing sections angled toward the rear. A tie bar extends rearwardly from the center of the shield-type support and bottom walls are located between the shield-type support and the tie bar. Boreholes are provided through the wing sections and through the free end of the tie bar, into which reinforcing bars are inserted to enable the bricks to be held together when stacking them in courses to form a retaining wall.

Abstract: A light-weight wall panel for a protective enclosure includes a shell of sheet metal which encases a filler structure of a combination of penetration resisting or hard wood and metal members. The filler structure includes first and second wall structures which differ from one another by the orientation of hard wood and sheets of expanded metal which are interleaved between adjacent ones of the boards. In the first wall structure adajcent one of the major surfaces of the wall panel, the hard wood boards and interleaved metal sheets have their major surfaces oriented perpendicular to the major surfaces of the wall panel. The second wall structure adjacent the other of the major surfaces of the wall panel has layers of hard wood boards and sheets of expanded sheet metal which extend with their major surfaces parallel to the major surfaces of the wall panel. The two wall structures are fastened to each other and hence into a single structure.
