Abstract:
The cavities (2a, 24) of a building element are filled with a mix (4) of heat-insulating and sound-deadening materials, preferably consisting of pumice and/or volcanic lapilli, in granular and/or powdery form. In a variation, the building element is just made up of said mix, and featured by a slab profile. The improved building element, obtained in this way, shows optimal features as far as sound-proofing, heat insulation, and heat resistance are concerned; there are no contraindications on its use, since it is made up of totally inert materials.
Abstract:
A building block (10) including at least one internal cavity (e.g. 12) is insulated by molding an insulating layer (24) from expandable thermoplastic polymer particles, such as beaded polystyrene, to one or more interior surfaces (26, 27, 28 or 29) of the cavity. The molding operation is carried out by positioning a male plug member (36) within the internal cavity of the building block with at least one peripheral surface of the plug member spaced from at least one interior surface of the cavity to provide a peripheral compartment into which the polymer particles are directed for molding the layer (24). Thereafter, steam, under pressure, is injected into the peripheral compartment to cause the particles to expand and fuse together into an efficient insulating layer that is expanded into close conformity with the interior surface(s) of the cavity. During the steam injecting operation a positive inwardly directed external force is applied to external surfaces of at least two opposed walls of the block to counteract internal forces generated by the steam. The invention also resides in the apparatus for carrying out the method of this invention, and in the building block formed in accordance with the method of this invention.

Abstract:
A siding member having longitudinally-oriented reinforcement fibers mateπal extending substantially the length of the member contained therein, and optional meshed reinforcement mateπal contained therein and/or an optional foam insert at least partially enveloped by a cementitious shell The siding member Is molded from cementitious slurry, including gypsum cement and latex/water mixture, or a hydraulic cement An amount of the slurry is added onto a bottom mold surface portion to a desired depth and/or weight, along with the longitudinally oriented reinforcement fibers and the optional meshed reinforcement material and/or any optional foam insert After sufficient curing, the siding member is removed from the mold and is ready for immediate use and/or further processing Alternatively, a continuous method is provided for producing relatively long lengths of siding that can be cut to appropriate size, without the need to produce individual siding members of limited size.
Abstract:
A method for producing a block having a flat bottom, a flat top which is parallel to the bottom and sidewalls which extend between the bottom and the top is disclosed. At least three cooperating mold parts are assembled on a first plate to produce assembled mold parts having interior surfaces which conform with the shape of the sidewalls of the block and flat, coplanar tops and bottoms. The assembled mold parts are clamped together, and a high slump concrete which is hardenable by hydration of cement therein is charged and worked as required into close proximity to the interiors of the mold parts and to the plate inside the mold parts. A foamable composition capable of forming a body of a thermoset, closed cell, urethane foam having a density of about 10 to 60 pounds per cubic foot which fills the interior of the assembled mold parts above the concrete therein is then charged, and a second late is clamped over the tops of the mold parts. Preferably, there are small openings between the interior and the exterior of the mold through which excess water in the concrete can flow without appreciable loss of cement or aggregate from the mold.
Abstract:
A method of manufacturing a thermally insulated building block (54a) comprises foaming a quantity of foamable plastics material in an enclosed space (56) between a building block (54) and a closure means (52), the quantity of material being sufficient to fill the enclosed space (56). The foamable material may be injected into a cavity in the block onto an outer surface of the block (54) or onto the closure means (52) prior to locating the block (54) and closure means (52) relative to each other to form the enclosed space (56) therebetween. The block (54) is transported between upper and lower parallel endless belts (55, 50) during foaming and either belt (55, 50) may provide the closure means (52). If the lower belt (50) provides the closure means (52) the upper belt (55) maintains the block (54) in contact with the closure means (52) during foaming.
Abstract:
A method and apparatus for facilitating the filling of insulation material into cavities (11) in hollow blocks (10). The apparatus comprises one or several drums (14, 15), which are arranged over a conveying means moving blocks past the apparatus. Through the drums pre-cut pieces (12) of insulation material are passed toward the block. In each drum (14, 15) a press plate (18) further is provided. Each drum is terminated downwardly by a laterally movable plate (16), which at each drum is provided with an opening (17) having a smaller width than the passageway. A reciprocating mechanism (22) is provided to move the press plate (18) to the rear wall (14) of the drum, so that the lowermost piece (12a) of insulation material is compressed, for example to half its thickness. An air distribution box (19) at the upper edge of the press plate includes air supply lines (20) and projects slightly in front of the press plate, so that the lower portion of the insulation piece (12b) lying above will be compressed more forcefully than the piece, which is about to be pressed out of the drum (14, 15) and into the block (10). Subsequent to completed compressing movement, compressed air is ejected through openings (21) in the air box (19), whereby the compressed lowermost piece (12a) is pressed over in the block. The lower more forcefully compressed portion of the insulation piece (12b) lying above acts as a dam and prevents the loss of compressed air.
Abstract:
Die Erfindung beschreibt ein lichtdurchlässiges Bauelement (1) auf der Basis von verschiedenen geometrischen Formen. Dieser Bauelement (1) besteht aus mindestens vier Grenzflächen (2,3,4) und (5), zwischen welchen sich eine Menge von lichtdurchlässigen, beliebig farbigen Spanten-Elementen (6) und dem nicht lichtdurchlässigen Material (7) befindet. Der Hauptvorteil der Erfindung gegenüber dem Stand der bisherigen Technik ist, dass das lichtdurchlässige Bauelement (1) zwischen allen seinen - mindestens aber vier - Grenzflächen (2,3,4) und (5) lichtdurchlässig ist. Die eingebetteten lichtdurchlässigen Spanten- Elemente (6), die in ein Spanten-Gitter (10) zusammengesetzt werden, können den Lichtstrahl nicht nur zwischen den gegenüberliegenden Grenzflächen - was der Stand der bisherigen Technik ist - sondern auch zwischen allen weiteren Grenzflächen übertragen. Falls mindestens zwei Spanten-Gitter (10) verbunden werden, entsteht ihre multiple Anordnung (21), deren anliegende Anschlussflächen (14) miteinander im direkten Kontakt stehen. Die Armierung (9) besteht aus einem tragfähigen Material und sie wird stückweise oder als ein verbundenes Gitter-Spanten-Element über die Spanten-Stege (19) des lichtdurchlässigen Spanten-Elements (6) eingebettet.
