Abstract: A ceramic board (1), of at least cement and gypsum, preferably in the proportions 1:10, and can include additional filler material in the composition. The board is used for various applications including as a door panel (31) or cabinet door (81). The board (21) can have channels, grooves, honeycomb, corrugations, or protrusions (22) extending along one or both faces which help to lighten the board whilst retaining rigidity, and which can have filler material (103) provided therein. The board (31) can have mounting points (35) for cabinet hinges or a lock, and can have internal strengthening members (142a,b,c) within the material of the board. The board or door can have an edge protector, which can be internal (153) or external (112). An end of the board can form a recess (184) for cables, pipes etc, which can be formed by internal strengtheners protruding from the end of the ceramic material (FIGS. 18a, 18b). The board can have an internal frame or skeleton embedded within the ceramic material.

Abstract: The present invention provides a system, method and apparatus for producing fire rated doors having added strength, better finishing and low cost manufacturing flexibility. The fire rated doors are made from two panels “sandwiched” together. An optional interior layer (e.g., fire resistant material, lead sheeting, steel or Kevlar) can be added between the door panels for various purposes. Splines, stiles or sticks are inserted in longitudinal channels in the door panels to provide assistance in aligning the door panels and greater hardware holding strength. An intumescent banding material concealed by a banding material around the perimeter of the door seals the door within its frame during a fire. The door design and the automated manufacturing process provide greater design choice, reduced cost and faster fabrication.

Abstract: A hollow metal door using hollow structural sections with closed cross section, along with the method for making same, is described herein.

Abstract: A repairable drawer or door assembly has a rear panel and a front panel that each have corresponding openings. Perimeter portions around the openings in the two panels are formed to capture a window. A removable escutcheon plate covers raw edges of the perimeter around the insert opening. The rear panel is fastened to the front panel to create an assembly that has no visible means of fastening on the exterior.

Abstract: An interlocking drawer or door assembly has a rear panel and a front panel that each have corresponding openings. Perimeter portions around the openings in the two panels are formed to capture an insert panel. An escutcheon plate covers raw edges of the perimeter around the insert opening. The rear panel is fastened to the front panel to create the assembly.

Abstract: An interlocking drawer or door assembly has a rear panel and a front panel. The rear panel is a five sided box, four low walls surrounding a face. One or more apertures are formed in two or more of the walls, and a plastic rivet or other deformable member is located in each of the apertures, such that the head of the rivet is on the outside of the wall. The front panel is a similar five sided box, with each of the four corners laser welded to form a smooth and hidden seam. Each of the front panel walls has an additional portion that is bent 180 degrees toward the inside of the box to form a rolled wall that is parallel to and in close proximity to the wall. Holes are formed in the rolled wall to correspond to the location of respective deformable members in the rear panel.

Abstract: A fire rated door with a surrounding door frame, consisting of a glass pane, which is embedded between its circumferential metal frame, said fire rated door consists of at least one door leaf realized from two glass panes spaced apart by means of profiles, whereby the glass panes extend almost as far as to the border of the door leaf and a transparent fire protection material is included between the spaced glass panes.

Abstract: An assembly structure of a super-high door includes two hubbed door skins and top, bottom, left and right edge-sealing angle bars. The door skins are positioned by flange ribs of the left angle bar. The top and bottom bars are positioned by notches at the top and the bottom ends of the left and right angle bars. The inner side of a first upper longer region (above the handle) of the left angle bar and the inner side of a second lower shorter region (below the handle) of the left angle bar are respectively inlaid with two U-shaped reinforcing irons having a length corresponding to that of the first and second regions. A wood strip with a length shorter than that of the left angle bar is inserted into the inner of the two reinforcing irons and is then closely joined to another wood strip of which the handle position is inlaid with a reinforcing angle bar.

Abstract: This disclosure relates to a composite structural member comprising a body part and multiple rigid strips which are attached to and separated by the body part. The body part is formed by a core having substantially flat parallel sides and opposed edges, and the opposed edges are covered by the rigid strips. As an example, the core is made of gypsum, and the strips are made of sheet metal. The rigid strips enable screw fasteners to be secured to the structural member. The sides of the core are preferably covered by side sheets.

Abstract: A lift door panel which, apart from a good sound and vibration damping with a high degree of rigidity, is producible to be largely distortion-free, wherein a warping in the case of fire and under high heat effect is reduced or avoided. The door panel has a front and back wall which are connected together by a first connection which is releasable under the action of heat and has at least a second heat-resistant connection.

Abstract: A stain/topcoat system for non-porous thermoset and/or thermoplastic articles comprises a pigmented stain having substantially only a single binder resin which promotes adherence of a topcoat, and a topcoat which is an aqueous dispersion of a film forming polymer and a curable organopolysiloxane microemulsion. The topcoat displays exceptional adhesion and weatherability to pigmented stained surfaces.
