Abstract: A multilayer steel-reinforced concrete panel assembly comprises a steel-reinforced concrete outer plate, a steel-reinforced concrete inner plate and a layer of insulation sandwiched between these plates. The outer plate and the inner plate are interconnected by flat anchors traversing the intermediate insulation layer and the anchors are distributed along an imaginary circle whose diameter is greater than the length of the small side of the rectangular panels. At least three such flat anchors are provided, two of which are capable of absorbing all of the stresses while all of the flat anchors are disposed symmetrically with respect to the longitudinal plan axis of the panel. The flat anchors take up all of the stresses to which the panel may be subject and thus eliminate the need for an additional anchor at the centroid of the panel, i.e. the center of stress forces and the like.

Abstract: A roof, or the like, composed of a plurality of blocks of relatively rigid insulating material which may be formed of Styrofoam. The relatively rigid blocks of insulating material being so configured that adjacent blocks will mate together forming a sealing means for the roof, or the like, which constitutes, in effect, a hermetic seal to thereby eliminate the possibility of temperature, moisture, etc. from entering between the blocks. The concept also involves the method of laying the plurality of blocks, whereby the sealing between adjacent blocks is aided by what I shall term an "UP" and "DOWN" arrangement of alternate blocks. The medium, which is rigid insulation, is intended to be used to form the insulating blocks will not accept adhesive so that a rubber or plastic sheet may not be caused to adhere to these relatively rigid insulating blocks when laid thereover.

Abstract: A building wall panel includes vertical studs welded to top and bottom channels to provide a rigid framework the maximum width of which is such that the panels may be transported over highways and the length of which is determined by the wanted wall height. Finish sheet material is secured to the inner or rear surfaces of the framework to provide an inner wall. Sections of insulating material are lodged in the rectangular spaces of the framework against a vapor barrier backed by the inner wall and dimensioned to be spaced from the outer surfaces of the framework. A vertically spaced, series of horizontal sub-girts has one secured to each channel and others secured to the studs and the sub-girts secured and the channels may be used to secure flashing. Metal panelling is secured to the sub-girts to provide an outer wall thus providing the panel with a dead air space. The framework is modified to meet door and window requirements.

Abstract: There is disclosed a device for securing refractory and/or insulating material against a furnace wall. The device comprises a metal pin or stud which is attached to the wall at one end and is provided with a plurality of notched portions adjacent the other end. The stud cooperates with a hollow, preferably ceramic anchor, which is provided with a rectangular slot that fits over the notched portion of the stud and may be secured thereon by rotating an anchor through 90 degrees to effect a locking arrangement. The anchors may be interfitted in order to provide a support for electrical heating elements. The significant feature is that the size of the anchor is such as to allow another anchor to interlock and make a collar which can support electrical heating elements. As the anchor is preferably a ceramic support it is electrically insulating, and prevents the electrical heating elements from contacting the studs.

Mechanism is provided for interlocking assembled ones of the prefabricated assemblies to form a wall structure including an inside corner. The side plates may be arranged for bending to form corners.

Abstract: A wire matrix for a construction panel has a plurality of parallel longitudinal trusses, each truss having a pair of parallel longitudinal wire runners and a plurality of transverse wire struts in which the struts associated with one truss are all parallel to each other and extend diagonally between the parallel runners, with the struts in alternate ones of the trusses being parallel and the struts in adjacent trusses being skewed. The trusses are formed by making a grid of parallel longitudinal runners joined by diagonal cross wires which are then cut between adjacent pairs of runners to form separate trusses. The trusses are then joined by transverse wire runners forming a three-dimensional matrix.

The procedure of hook and snap-lock assembling a panel structure may be performed by hand; by utilizing the assistance of tools disclosed; or by utilizing other mechanical aids.

Abstract: This disclosure pertains to a clamping apparatus having a stud capturing portion and a stud facing portion bolted together so as to compressively support a radiation proof sheet material, such as lead sheeting, there-in-between. The interior wall covering material, such as panelling or wall board is secured to the external surface of the stud facing portion. No nails are required to support the radiation-proof sheeting material, thereby minimizing accidental leakage due to harmful radiation passing through openings inadvertently disposed in the radiation-proof sheeting in the conventional nail securing supporting thereof. A pair of radiation-proof tracks capture the free ends of the stud capturing portion and the stud facing portion.

Abstract: A batten assembly for use in sealing the edges of roofing sheets includes a plurality of clips secured to the roof at spaced intervals along the slope of the roof with upward extending legs which pass through longitudinal slots in outwardly extending flanges along each side of the lower portion of a batten and are bent inward and downward over the upper edges of spaced apart longitudinal side walls of the batten to firmly secure the batten to the roof. The edges of the roofing sheets are bent upward and then inward and downward over the batten side walls and the legs of the clips and are retained in place by a cap strip which is secured to the batten by bolts threaded into sliding nuts engaged by internal flanges in the batten. A continuous longitudinal cross member in the batten, below the internal flanges, forms a water-tight channel with the side walls to carry off water which could seep into the batten over the top edges of the roofing sheets or around the cap strip bolts.
