    (5t) CONSTRUCTION ELEMENT FROM A PLASTER AND A METHOD OF ITS MANUFACTURE
    one
    The invention relates to the construction, in particular to a building gypsum-based construction element, intended for the installation of ceilings or vertical fences.
    Known construction element of gypsum in the form of a plate with reinforcement having a bend zone formed by the cutouts of the body of gypsum. The element is made with coated paperboard. In order to allow the edges to be bent in the gypsum, a groove is arranged, while being careful not to damage the cardboard finish on the side that serves as the hinge.
    A method of making a gypsum building element in the form of a slab with reinforcement divided therein and having a fold zone with the cuts of the gypsum body includes pouring a liquid gypsum mixture, forming the element, removing the gypsum along the planes bounding the fold zones 1 j.
    The disadvantages of this technical solution are the gypsum's fragility, when the cardboard finish is weakened or when it disappears as a result of moisture, fire or careless handling, the need for final finishing of the surface of the cardboard and increasing the resistance to impact.
    The purpose of the invention is to increase the strength of the gypsum element.
    The goal is achieved by the fact that in a gypsum building element formed from a reinforced slab having cuts in the bend zones, the armature is located unevenly over the thickness of the slab with its concentration in the bend zones.
    The reinforcement is made of threads of woven or non-woven material based on them or a combination of threads and material.
    The building element is made of slabs consisting of three panels, the outermost of which is smaller than the central one, and has a box-like shape formed by the central and outermost panels positioned at an angle of SSSS. Extreme panels have a height equal to} / kQ element length. The fold zones are located at the level of the lower side of the central panel, its upper side and in the middle plane. The cavity of the box-like element is filled with insulating material. To obtain a slab with zones of bending according to the method of making a gypsum building element, including pouring a liquid gypsum mixture with reinforcement distributed in it and molding, during the molding process, the reinforcement concentration in the bending zones is produced by ribs or discs acting on the reinforcement from the bottom and / or from above The reinforcement concentration is produced upon reaching a yield of the mixture of 100 mm and continues to a yield of 60 mm, and the gypsum above the reinforcement lines in the bend zones is removed after reaching a yield strength of 60 mm. FIG. 1 shows a slab with reinforcement placed along certain lines; in fig. 2 - gypsum board. divided into panels by fold lines; Fig. 3 shows an example of a combination of reinforcement placed in a plaster; in fig. - building element, folded harmonic; in fig. 5 box or channel made of the building element; in fig. 6 - box-shaped element; in fig. 7, 8, and 9 box-shaped elements, in which the fold lines are located at different levels in the thickness of the plates; in fig. 10 - box-shaped element containing insulating material; in fig. 11 is a diagram of an apparatus for manufacturing building elements; in fig. 12 is a variation of the device for concentrating the reinforcement. The construction element of gypsum is formed from reinforced slab 1, which has cutouts in zones 2 of the fold. The armature 3 is located unevenly across the thickness of the plate 1 and is concentrated in zones 2 of the fold. The armature 3 is made of woven or non-woven filaments based on them or a combination of filaments and material. The building element {FIG. 1 and 2) reinforced, for example, by a set of reinforcing elements made of glass (Fig. 3) - Thus, it is possible to make reinforcement with a layer of continuous, crimped and intertwined reinforcement threads 3, covering the top and bottom with a network of glass 97 5 preventing the layers of the reinforcement 3 from excessively bulging in the thickness of the product and preventing the twisted reinforcement 3 from leaving the product or making them invisible on the sides of this product. As the reinforcement, textile yarns, natural or synthetic, can be used; in this direction, to provide a connection between two panels ;, metallic yarns are separate segments or layers, woven materials, nonwovens, layers of continuous glass yarns similar to the reinforcement layer 3, organic or mineral fibers, for example, made of glass, provided that some of them are located transversely to the lines of the fold zones 2 and that their length is such that they can provide a connection between two Aneli, i.e. at least 5 cm for plaster tapes with a thickness of approximately 6 mm. The building element is made of three panels. The outer panels 6 and 7 are smaller than the central 8. The building element has a box-shaped shape formed by the central 8 and the outermost 6 and 7 panels located at an angle of 85-95 °. In zones 2 of the fold, the gypsum is removed and only the reinforcement of the 3Zones 2 of the fold is located is limited to panels 6, 7 and 8, which can rotate one relative to another around the lines formed by zones 2 of the fold. Inside each panel 6, 7 and 8, the armature 3 is located in the thickness of the product along the lines of the fold zones 2. The boundaries of gypsum of each fold line, relating, on the one hand, to the extreme panels 6 and 7, and, on the other hand, to the central panel 8, have an open Y-shaped profile with an angle close to 120. The extreme panels 6 and 7 are bent from the central panel 8 at an angle of 90 to get a U-shaped element. This angle depends on the purpose of the box element. In some cases, extreme panels 6 and 7 are folded over an angle slightly larger than 9P (approximately 95) in order to obtain a U-shaped element with covering extreme panels 6 and 7, or in another case at a smaller angle (about 85), in order to obtain a slightly open U-shaped profile. The outer panels 6 and 7 have a height equal to 1/40 of the length of the module of the building element, that is, approximately 5 cm by 2 m of length. 59 The fold zones 2 are located at the level of the lower side of the central panel 8, its upper side or in the middle plane. The lines of the fold zones 2 can be parallel (Fig. 2) and non-parallel, if it is necessary to bend channels or ducts, for example, in the form of a truncated pyramid. FIG. 1 and 2 the plane that contains the reinforcements along the bend lines is medium-O
    This is a plane parallel to the sides of the slab 1. This plane containing the lines of the fold zones 2 can be located near one of the sides of the slab, on the surface of the slab or on any other IS level. The width of the line of bending zones 2 that do not contain gypsum depends on the thickness of the plates, the height of the plane containing the lines of the folding zones 2 in the thickness of the plate, the direction of the bending of the panels relative to each other and the bending angle. Plate 1 can be folded with a harmonic (Fig. 4) to produce a building element, which can be used, for example, to install decorative partitions or ceilings in several panels. From plate 1, building modules (Fig. 6) can be manufactured, having a central panel 8 and two extreme panels 6 and 7 of smaller width, separated from the central panel 8 by fold lines 9 and 10, not containing gypsum and consisting of reinforcement 3 plates 1, assembled jj gypsum plates 1. For this, by running along these lines into one single, periodically or continuously filling middle plane. Elsewhere, the liquid mixture from the building hypo is distributed throughout the thickness of the sa and water with a flowability greater than 120. Isisdel or evenly in this thickness according to F.L.S. give the expression tene, or in the form of multiple layers, the density in millimeters. It encloses placed at different levels. Plate 1 can be folded to form ducts for ducts or ducts (Fig. 5), for example, to be placed around metal structures and to protect them from fire, in which case insulating material 11 is placed between the metal structure and the gypsum duct (Fig. 10). Connect the dbe edge panels 6 and 7 to the center 8 by using plaster, placed inside the fold, or by using hot-melt glue. In addition to the insulating material, mineral wool or polystyrene or phenolic foam type foam is placed in the box-like element thus obtained. Insulating material 11 can be glued to the extreme pane to retain the bent edges, reinforcement or excess glue or plaster is required, forming a roller 16 and 17 inside the fold and along the hinges 12 and 13 .. 0 l m 6 and 7 or over the entire surface of the panel 8. The level of lines 9 and 10 of the fold in the thickness of the slabs depends on the purpose of the box element. The bending can be performed around the hinges 12 and 13 (Fig. 7) located at the level of the upper side of the plate 1, and the edges I and 15 of the box-like element have in this case the profile of stair steps. The bending can be done around the hinges located at the level of the lower side of the plate 1 ( Fig. 8), the lower edges And and 15 in this case have an angular profile. When bent along the hinges 12 and 13, the two bevelled edges 18 and 19 of maximum length can be glued together with one another. Bending can also occur around the hinges 12 and 13, located in the thickness of the plates (Fig. 9), regardless of level. The fins 1 f and 15 of the box member in this case have a beveled profile, and the beveled edges 18 and 19 have an average length between the maximum length. which they have in the case shown in FIG. 8, and zero length in the case shown in FIG. 7Production of building elements begins with the manufacture of reinforced plaster with a diameter of 60 mm and a height of 59 mm, installed vertically in the center of a polished metal plate or a plate of glass, with gypsum mixed with water. At time T, relative to the time t at the beginning of the contact of loose gypsum with water, the cylinder is removed and, thus, gypsum is released, which spreads over the slab and forms a disk whose diameter is measured. The measurement of this diameter constitutes the yield point F at time t. An armature is placed in the liquid mixture either specifically before pouring, when it is produced periodically, or before, during or after pouring, when it is produced in a continuous manner.
    Begin to change the position of the reinforcement along the lines that will become the fold lines, and concentrate the reinforcement along these lines as possible in the same plane when the gypsum mixture is; still liquid, t, e. at the moment when its fluidity according to F.L.S; did not reach 100 so that the plaster set on the reinforcement, the position of which will no longer change. The change in the position of the reinforcement along these lines continues at least until the flow of gypsum is about 60 F.L.S. it is necessary to place the fold line at half the height in the thickness of the gypsum board, simultaneously acting on the upper and lower sides of the gypsum board. When the plane of the fold lines is brought to the level of one of the sides of the slab, 1, either the upper surface is affected in order to bury the reinforcement to the lower side, or only the upper side in order to raise the reinforcement to close proximity to the upper side. In addition, the gypsum mix is located above the fold lines or, starting from the moment the gypsum reaches a yield of F.L.S equal to 60, the gypsum on them is removed from these fold lines. This can be done before the gypsum fluidity is 60 FLS, but if it is required that the groove, which is thus obtained, is not filled with the liquid mixture again, it is necessary to continue this until the fluidity reaches 60 or close to 60 The panel can be left to dry with only one reinforcement concentrated along certain lines, without removing the gypsum above these lines. The removal of gypsum is carried out after the panel dries, for example, at the time of its application without danger of damaging the reinforcement, since these reinforcement are concentrated in one plane. At the bottom of the molding device, the fins 20 (Fig. 11) are placed. They hold the reinforcement in a raised position along the fold lines and press profiles to the top of the plate, which are located exactly above these ribs. These profiles and fins align the reinforcement in the same plane along the future fold lines, and also prevent the mixes from being placed on the fold lines. If the fold lines are to be located at half the thickness in the gypsum board above the ribs 20, a row of discs 21 are placed in the upper part of the cast gypsum board, which are buried in the reinforcement.
