Abstract

The invention relates to building construction and to the production of building products and can be used for constructing low rise residential, industrial and administrative buildings for different climatic zones. The invention increases the quality of products having a complicated geometric configuration, extends the range thereof and makes it possible to obtain the precise geometrical shape of the products. The inventive universal multicavity cassette mould is embodied in such a way that it is multisectional and has the form of crest-forming elements rigidly fixed to a frame, articulated drop sides being also fixed to the frame. Groove-forming and crest-forming elements are fixed to the opposite longitudinal sides, respectively. The articulated drop sides are provided with locking elements, the upper groove-forming elements being disposed in such a way that they are dismountable.

    • DISCLOSURE OF THE INVENTION
  • The engineering effect of the invention consists in improving quality and widening the range of structural elements having a complicated configuration as well as in obtaining a high-precision geometrical shape and improving productivity.
  • The engineering effect is accomplished owing to that, in the general-purpose casing form for the manufacture of groove-and-crest plates from structural mixes, comprising a supporting frame, a casing form with separating walls, and upper groove-forming members arranged to be disposed strictly above crest-forming members attached to the frame, the casing form is made so that it is a multiple casing form consisting of the crest-forming members fixed rigidly to the frame, and longitudinal and end-face drop sides hinged to the frame, wherein attached to the opposite longitudinal sides are respectively the groove-forming members and the crest-forming members, the end-face drop sides are provided with locking members, the upper groove-forming members are removable, the separating walls defining the forming compartments are mounted so that the latter are readjustable, and wherein the groove-forming members and the crest-forming members are made of an elastic material, for instance, plastic or rubber, the upper removable groove-forming members are made so that they have a trapezoidal or semicircular or, else, semi-oval cross-section, the separating walls are made of a metal having a polished inner surface, and the separating walls of the forming compartments are further provided with elements for producing three-dimensional decorative patterns on the front face of the structural elements.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • The invention is now described in detail with reference to the accompanying drawings, where:
  • FIG. 1 illustrates the general-purpose multiple casing form for the manufacture of groove-and-crest plates from structural mixes, shown when the sides thereof are half-open;
  • FIG. 2 is a longitudinal sectional view of the general-purpose multiple casing form along line A-A;
  • FIG. 3 shows how an upper groove-forming member is arranged to be disposed;
  • FIG. 4 is a sectional view of the crest-forming members;
  • FIG. 5 is a sectional view of the groove-forming members;
  • FIG. 6 is a lateral sectional view of the general-purpose multiple casing form; and
  • FIG. 7 is an example of finished structural element.
  • The general-purpose multiple casing form for the manufacture of groove-and-crest plates from structural mixes comprises (FIGS. 1, 2 and 6) a frame 1 with crest-forming members 2 fixed thereto on the horizontal plane thereof, longitudinal drop sides 3, the crest-forming members being provided with seats 4 (FIGS. 3 and 4), groove-forming members 5 (FIG. 5) and crest-forming members 6 (FIGS. 3 and 4), end-face drop sides 7, upper removable groove-forming members 8 that are mounted above the crest-forming members 2 (FIG. 3), separating walls 9, hinges 10, and locking members 11. The crest-forming members 2 and 6 and the groove-forming members 5 are made of an elastic material, for instance, plastic, rubber, etc. The separating walls 9 are made of a metal having a polished surface and they are mounted so that the forming compartments are readjustable. Besides, the separating walls 9 of the forming compartments are further provided with elements for providing three-dimensional decorative patterns on the front faces of the structural elements. The upper removable groove-forming members 8 are made, for instance, so that they have a trapezoidal or semicircular or, else, semi-oval cross-section.
    • THE BEST EMBODIMENT OF THE INVENTION
  • The general-purpose multiple casing form for the manufacture of groove-and-crest plates from structural mixes operates as follows.
  • Prior to pouring the structural mix, the longitudinal drop sides 3 and the end-face drop sides 7 are to be brought to their upper vertical position and braced by the locking members 11. Next, into the gaps between the groove-forming members 5 and the crest-forming members 2 and 6, the separating walls 9 are to be installed and, if necessary, they are installed together with the elements for providing three-dimensional decorative patterns on the front faces of the structural elements, whereupon placed in the seats 4 of the members 5 and 6 are the upper removable groove-forming members 8. The compartments thus defined are then filled with the structural mix poured therein and, after the mix gets set, dismantling of the casing form is carried out. Thereupon, the locking members 11 are opened. Through the use of the hinges 10, the longitudinal drop sides 3 and the end-face drop sides 7 are shifted to their lower position with respect to the frame 1. The dismantling is carried out by way of removing the upper groove-forming members 8 from the structural element thus formed, followed by removing the separating walls 9 from the structural element that has been produced. As a structural mix, use is to be made predominantly of fast-hardening mixes, for instance, the mixes that are based on composite gypsum binders, portland cement and microsilica.
  • Varying the spacing between the separating walls 9 installed in respective grooves between the groove-forming and crest-forming members 2, 5 and 6, structural elements having different constructional and thermal-physical parameters can be produced, which may find use in construction engineering, ranging from internal partitions to multiplayer external fencing structures.
  • By mounting additional elements for providing three-dimensional decorative patterns to the separating walls of the forming compartments, it is possible to provide various ornaments, figures and other three-dimensional patterns on the front face of the structural element.
    • INDUSTRIAL APPLICABILITY
  • The general-purpose multiple casing form for the manufacture of groove-and-crest plates from fast-hardening structural mixes based on a composition of gypsum binders allows to improve quality of the structural elements owing to possible variations in their constructional and thermal-physical parameters. Besides, it allows widening the range of structural elements having a complicated configuration and obtaining a high-precision geometrical shape of the structural elements thus produced, i.e., it provides accuracy within ±0.5 mm when fitting the structural elements, thus ensuring that the wall has an ideally smooth surface without any projections at the joints (FIG. 7). Besides, the general-purpose casing form allows providing three-dimensional decorative patterns on the front faces of the structural elements.
