Abstract: A method and apparatus for installing the outer members of a curtain wall comprising a plurality of spring-loaded tab members connected to curtain wall panel members and swingable into or out of supporting connection with corresponding stop members, said stop members being fixedly connected at predetermined positions to the vertical side rails of the curtain wall frame members. The tab members transmit the gravity load and wind load of the panel members to the curtain wall frame members through said support members.The individual curtain wall sections are positioned in the vertical guide members of the curtain wall frame at any convenient location (e.g.: ground level) and raised therein to a mounting position. The respective tab members rotate around the stop members as the curtain wall section is raised but are biased outwardly to prevent said curtain wall sections from being lowered, as by the force of gravity.

Abstract: A prefabricated elevator shaft includes a stack of self-supporting prefabricated shaft modules whereby upper shaft modules are supported on lower modules. Each module is of rectangular cross section and vertically spaced portions at each corner define a void between two adjacent modules. The voids are filled with a resin which, after joining together, forms a solid bed supporting the upper module in all directions. On the upper module, screw jacks extend into engagement with the lower module for vertical adjustment. On the lower module, removable guide shafts extend vertically and engage corresponding apertures in the upper module to locate the modules horizontally relative to one another during assembly of a elevator shaft. When the modules are satisfactorily located, the guide shafts can be removed and replaced with bolts to secure the upper module on the lower module.

The insulating material is wedge-shaped, and it fits into a space between said supportive parts which is defined by walls which extend inwardly from the top of the building block to its bottom.

Abstract: A sash window is formed from a frame profile and a sealed window unit comprising a pair of spaced parallel glass panes. The frame profile includes a channel section with a tranverse web and upstanding side walls which are formed integrally without separate stops and integrally with a support element for the window frame. The frame profile is manufactured by pultrusion to provide a coefficient of expansion very close to that of glass. The sealed window unit is sealed to the window frame by a bead of sealant material only at the corner between the inner face of the window unit and the tranverse web supporting the side edge of the window unit. The sealant is thus protected from exposure to the elements. A drainage opening is provided in the web to allow the escape of moisture passing between the direct contact between the outer side wall and the outer face of the window unit.

Abstract: A non-progressive clean room wall assembly comprising an extruded framing member as a means of joining panels, and framing windows and doors. Each framing member has an elongated body with front and back side. The front side being seamless to prevent particulate accumulation, with wall panel support flanges to hold wall panels, window panels, or doors. Glazing spline is inserted into receptor grooves on the side to secure the panels in place. The back side of the framing member has a channel shaped utility chase area to hold fittings which secure the framing member to the floor or ceiling or another framing member, as well as attaching mechanical and electrical equipment. A channel closure strip may be inserted into the utility chase area to form a double wall system with two equal front sides whose flanges hold a thicker double wall panel. Both single wall and double wall assemblies may be installed and demounted from the back, outside the clean room environment.

Abstract: This invention relates to a device for joining two building units one of which is load-bearing and the other load-imposing. A conventional solution for joining e.g. a column and a beam is to form a sideward projection in the column for supporting the beam. This kind of projection complicates considerably the casting of the column and remarkable shearing forces are formed therein. In the invention these drawbacks are eliminated by fastening to the building units anchoring means which do not project from the column, at least not from the side surfaces thereof, and by positioning them in the building units in such a way that points at which the anchoring means extending from one building unit to the other are fastened to the building units are positioned in a completed joint at a distance from each other in the vertical direction.

Abstract: The device has square frames mounted at a distance from each other and with parallel planes on the wall. In the interior of the frames extend ducts, preferably of a lattice structure, which are exchangeably disposed. Furthermore, the frames are used as supports for exterior facing plates. One of the sides of the frames is connected via a hinge with an adjacent side and (together with the facing plate fastened thereon) is outwardly pivotable. Apparatus supports for electric sockets, etc., are mounted in optional locations, also inside the frame cross section, on ducts or on special intermediate supports. Great flexibility with respect to the total cross section, arrangement, fitting with apparatus and choice of facing is made possible.

Abstract: A system is provided for use with structural steel members' lying in a corrosive atmospheric environment such as marine, wherein the system protects the members against corrosion. An elongated rigid envelope (20,22) that is gas tight surrounds the structural members (12,14) and extends along their lengths. A source (27) of pressured inert gas such as nitrogen is coupled through a regulator (25) to the inside of the envelope and maintains a pressure therein slightly greater than atmospheric. For wide flange members, the envelope's cross-section is preferably rectangular. Semi-globular protrusions (71,73,74,76), and (81,84,85,88) at the inside corners of the envelope and additional semi-globular protrusions (82,83,86,87) keep each side of the envelope moldings slightly spaced from the flanges of the members. The large space (26) provides a reservoir for inert gas, while providing minimum surface area of the envelope through which inert gas can be lost.

Abstract: Ceiling panels, formed from metal rods welded together in a grid pattern, are easily installed in suspended subceilings of the type in which panels are supported on bottom flanges of a framework of inverted T-bar rails. In a lower layer of the panel, an array of spaced parallel rods is tied together across each end by an end rod to form a perimeter which fits within a cell opening of the inverted T-barsupport framework, while rods in an adjoining upper layer of the panel, oriented perpendicular to the rod array in the lower layer, are made to extend beyond the lower layer perimeter so as to support the panel, along two opposite panel edges, upon the upper side of bottom flanges of the support frame rails. The perimeter rods in the lower layer in combination with with the exposed portion of the support rail flanges produce the finished effect of a uniform border around each panel.
