The present invention relates to a method for forming a panel that has rows of partially embedded elements (4), wherein the elements (4) are laid in rows separated by a spacer on the bottom of a mould (1), and the assembly is subsequently covered with a mortar (7), said mortar (7) setting to yield the panel. The invention is characterized in that at at least one longitudinal side of a row of elements as the spacer a hollow flexible hose (2) is used, and the mortar (7) is applied in a state of the hollow hose (2) where it is in close contact with the longitudinal sides of the elements, and the mortar (7) is subsequently set.

There is provided a lightweight plaster board having a cellular porous plaster core, excellent in adhesion to a covering base paper for a plaster board, free from dry-out in side edge parts of the plaster board, and with no disadvantage in workability for driving a nail into the plaster board. The plaster board includes a plaster core having a front surface, a back surface, and four side surfaces, and at least one covering base paper that covers the front surface, the back surface, and the at least two opposite side surfaces of the plaster core. The plaster core includes one or more hard edge parts each including one of the side surfaces covered with the covering base paper, one or more high-density parts including the front surface or the back surface, not including the side surface covered with the covering base paper, and having a density substantially equal to the density of the hard edge part, and a low-density part having a density less than the densities of the hard edge part and the high-density part and contacting with the hard edge part and the high-density part. The hard edge part does not include a position in which a nail is driven.

A support tray for ceramic tesserae, used in a process for realising ordered matrices of ceramic tesserae, comprises a rest unit (2) of the ceramic tesserae (3), made of an elastically deformable material which is non-stick and glue-resistant so that it can detach, and has a first surface (4) which is provided with a plurality of cells (5) for housing the tesserae (3). The tray (1) further comprises a support unit (7), made of a rigid material, for the rest unit (2). The rest unit (2) and the support unit (7) are distinct and couplable by means for mechanically coupling (9).

A method and a device for producing gypsum boards which can minimize the occurrence of defective products and provide an excellentand efficient continuous productivity, wherein a partial breakageof overlay paper and/or underlay paper caused by foreign matters and the like mixed during a continuous production of gypsum boards can be quickly detected by using a method of measuring an electric current flowing between an upside molding machine and a downside molding machine by taking advantage of the facts that gypsum board base paper is insulating and gypsum slurry held between sheets of the base paper is conductive, and, in addition, foreign maters causing a breakage of the paper can be easily removed without a partial breakage of paper developing into a widthwise cut across the paper and without suspending the production of gypsum boards, thereby enabling a stable continuous production of gypsum boards.

The invention relates to a method of producing plaster boards (12) in which two bound sheets of paper, namely one cream paper (3) and one grey paper (4), enclose a plaster-based hydraulic binder (2) in a former (7), thereby creating a composite strip (10) which hardens on two hardening strips (8 and 9), said strips having two horizontal tapering strips disposed along the edge thereof. The invention is characterised in that it consists in: shaping the cream paper (3) along emboss lines (20); providing stiffening slots (23) on either side of the emboss lines (20); reinforcing the mechanical strength of said emboss lines (20) by covering same with a coating (15); allowing the emboss lines (20) to exceed the aforementioned former (7) and the hardening strips (8 and 9) and generating the double slope imprint (19); and, subsequently, cutting the composite strip (10) to the right and at the middle of each double slope imprint (19).
摘要:
A decorative paving tile or panel comprises a plurality of irregularly shaped stone elements of the same or differing thickness embedded in a backing layer or base to form a tile or panel of the predetermined thickness wherein the normally exposed surfaces of said stone elements lie in a plane substantially parallel to a mounting surface of said backing layer or base. A flowable displacement material may be employed in the interstices between adjacent stone elements and/or a boundary wall of a tile or panel mould to forma grouting channel. An irregular space between adjacent stone elements of adjacent tiles or panels allows the formation of an optically seamless tiled or panelled surface when grouted.
摘要:
A method for the surface treatment of a substrate, for example concrete roof tiles, comprising spreading a layer of water-containing hardenable paste containing binder and other particles, for example a cement based slurry, covering the paste layer with (a) a flexible membrane or (b) a plate or (c) first a flexible membrane then superimposed thereon a plate, the plate or membrane having an upper-surface and a smooth under-surface, optionally vibrating the membrane-covered or plate-covered area of the paste layer, such that vibration is transmitted through the membrane or plate, to the paste layer, and either removing the membrane, plate or plate and membrane then hardening the paste layer on the substrate , or at least partially hardening the paste layer on the substrate with the membrane, plate or plate and membrane in place.

The invention concerns a method for making boards (9ter, 11) based on a hydraulic binder such as gypsum plaster, having thinned edges (10). Said method is characterized in that it comprises, prior to passage in the die (4, 403), a lath (6, 23) is extracted from a lath magazine (20) and said lath (6, 23) is inserted beneath the skin (1) of the board. The invention also concerns a line for producing such boards (9ter, 11) and a device for inserting laths (6, 23) beneath the skin (1).
摘要:
The invention relates to a method for production of sheets made from binder, in particular plasterboards with recessed edges. Said method comprises the following steps: 1) generation of a marking (301) on a face (2 or 3) of the pre-form (5); 2) detection of the marking (301) and 3) transmission of an actuation signal to a cutting device (9) for the pre-form (5). The invention further relates to a production line for said sheets, and a unit, particularly for the generation of an impression (12, 12bis) in a pre-form (5). Said unit comprises a frame (101), first (102, 103) and second pulleys(105, 106), two belts (108, 109) around the pulleys (102, 103, 105, 106) and at least one line (111) running between said belts (108, 109), such that the axis thereof is parallel to the axis of the pulleys (102, 103, 105, 106).
