Abstract:
A single piece mineral wool insulation panel having a height of at least 160 cm and a width of at least 60cm has an upper band located towards an upper edge of the panel, a lower band located towards the lower edge of the panel and a central band positioned between the upper and lower bands, each of the bands extending substantially across the width of the panel. Different densities of mineral wool are arranged at at least the upper and central bands and the panel is particularly suitable for use to fill the cavity of a fire rated door.
Abstract:
A method for embedding glass lites (5) into door slabs (1) comprising embedded area covered with sheeting (2,3) on both sides and a fill (4) in-between and in order to embed the lite (5) an opening (6) is made in the one side of the slab (1) with the shape similar to the shape of the lite (5) increased by an around perimeter gap (7), characterized in that, in the sheeting (2) in the other side of the slab (1) an opening (10) is cut, concentric with the opening (6) in the first side of the slab and smaller than the opening (6) by value of k of about 10 to 30 mm around the perimeter. The slab (1) is placed with the smaller opening (10) down a flat surface (11) and on the surface of the sheeting (3) around the opening (6) weights (12), are placed causing a stress not greater than 2,5 MPa, Then spacers (14) are placed on the edges of an inner surface (13) of the sheeting (2) around the smaller opening (10) and an adhesive (15) is applied and the lite (5) is placed maintaining a uniform gap (7) width over the entire perimeter, and then the lite (5) is pressed down, and after the adhesive (15) is cured, the gap (7) is filled with an expanding polyurethane foam (8). After drying, the foam (8) excess is removed, so it is flush with the surface of the sheeting (3) then on the edge of the sheeting (3) and the edge of the lite (5) the adhesive (15) is applied and a masking cap (9), is placed on the applied adhesive. Instead of the adhesive (15) a double-sided adhesive tape is used to attach the masking cap (9) to the lite (5). The corners between the edge of the smaller opening (10) in the sheeting (2), and the surface of the lite (5) on the one side of the slab (1) and the corners between the edge of the opening in the masking cap (9) and the surface of the lite (5) on the other side of the door slab (1) are filled with a silicone sealant (15). During varnishing of the slab, the outer surface of the sheeting (3), designated to be covered with the adhesive is protected with masking tape (16), which is removed after varnishing.
Abstract:
The invention relates to a method for producing a fire prevention closing wing (33, 16), especially a fire door panel (16), comprising an outer housing (7, 19), especially made of sheet metal and enclosing a filling material (13) made of mineral substances (2, 25) and binding agents (6). The aim of the invention is to produce a fire prevention closing wing in a cost-effective manner. In order to achieve this, the outer housing (7, 19) comprises a cavity which can be accessed from outside by means of at least one housing opening (11, 22), said housing opening being preferably smaller than the cavity in terms of length and/or width. A mineral-based loading agent (2, 25), either in bulk or in liquid form, and an inorganic binding agent (6) are introduced via the at least one housing opening (11, 22) to form the filling material (13). The invention also relates to a device for carrying out said method and a fire prevention closing wing produced (13) therewith.
Abstract:
The invention relates to a lightweight construction board, with an external frame (1) and a centre (2), whereby both frame and centre are of the same strength of material and an upper and lower covering board (3, 4), which cover the frame (1) and the centre (2). The centre (2) comprises an inner part (2a), in a lightweight material and an upper and lower finishing layer (2b, 2c). Said board is characterised in that it is particularly stiff and, furthermore, the transition between frame (1) and centre (2) is no longer apparent on the upper surface of the board.
Abstract:
A door comprises a door frame having frame-members (1-4), which extend along the edges of the door. The door is clad on one flat side thereof with an outer panel (8) which is nailed to the frame members and also to at least one nailing batten (9, 10). The nailing batten has a thickness which is smaller than the thickness of the frame members. A continuous sheet (5) of insulating material provided with grooves (11, 12) for accommodating the nailing batten fills the hollow cavity located inwardly of the door-frame members. The insulating sheet (5) and the door-frame members (1-4) surrounding the insulating sheet are covered on each flat side thereof with a covering sheet (6, 7), to which they are glued. The door is manufactured by forming an insulating sheet (5) which fits into the space located inwardly of the door frame and which has a thickness corresponding to the thickness of the door frame, by forming in the insulating sheet one or more grooves (11, 12) whose depth is smaller than the thickness of the sheet, and by placing nailing battens (9, 10) in the grooves (11, 12) and gluing the insulating sheet (5), the nailing battens located in the grooves, and the frame-members (1-4) to the covering sheets (6, 7), and then nailing the outer panel (8) to the door structure thus obtained.
Abstract:
Provided are door systems having a plurality of door panels and a frame, the door panels being movable horizontally between an extended position closing an opening in a building structure, and a folded retracted position opening the opening in the building structure. When in the extended position, the door panels interlock with each other forming a barrier to wind, dirt, dust and insects. The frame is movably attached to the building structure and when the door panels are in the extended position, the frame moves and engages the door panels with a sealing member to provide an airtight seal of the opening in the building structure.
Abstract:
A door (100) comprising a single panel (20) folded to form a latch face (53) and first and second main faces (52, 54) of the door. The door preferably further comprises edge tabs (36) folded to form upper, lower and hinge faces of the door. The panel is preferably a composite panel comprising an inner metal sheet (65), an outer metal sheet (66), and a plastics core material (67) between the metal sheets.
Abstract:
A door assembly may include a door defining a first face, a second face opposite the first face, and an opening formed there through from the first face to the second face, a glazing mounted to at least the first face of the door about the opening, and a recess defined in the first face of the door about the opening. The glazing may include a first panel unit defining a first exterior surface and a first interior surface opposite the first exterior surface, and a second panel unit spaced apart from and facing the first interior surface of the first panel unit. The recess may be sized to receive therein the first interior surface of the first panel unit of the glazing with a plane defined by the first exterior surface of the first panel unit substantially flush with a plane defined by the first face of the door.
