     inside the tank 12, thermo-insulated with a thermal insulating composite wall according to the present invention, and this internal SLO.I is made of an elastomer, for example, an elastomeric polyurethane U1I from an epoxy syule, which has a flexibility.
    Referring to FIG. 1, the Cornus of the supporting beams 5 and b, as well as the angular pro- duct: heel 8, is made of high density Tajia foam (for example, about 150–200 kg / m), whereas the body is pan. Oil spruce 4 is made of medium grade non-polyurethane urethane (about 80 kg / m). The indicated thermal insulation of the schun elements could also be removed from non-polyvinyl chloride.
    FIG. The method of fastening the supporting beams 5 and 6 on the self-supporting wall 1 is shown. To this end, shishki 3 and 14 are welded with equal spacing in the front: zone of the supporting beams, I-Ja- against each stud of the support 1.; e beams have a cylindrical recess: 15 (stud studs 1 3) and 16 (for stud 14), which has an axial bore in the spo: I 7 (; p7 depressions 15) and 1 8 (for the corner) pin 16, and through the hole passes the corresponding hairpin The bottom of each recess 15 or 16 is reinforced with a plywood or laminated washer which predominantly adheres to the named bottom inside the corresponding opening, the support beams 5 and 6 are attached to the self-supporting wall I by means of the said studs by blocking the bottom of the recesses to the filling substance layer 19 by means of nuts 20 and 21. At the same time, these nuts are preliminarily blocked or locked using an adhesive composition, such as epoxy adhesive. The recesses 15 and 16 are provided with gating bushes of thermally insulating material: a sleeve 22 for the recess 15 and a sleeve 23 for deepening 16, and this substance is, in particular, the same as the substance constituting the housing 24 or 25 supporting beams and these bushings are tightly connected to the body of the support beams by means of an adhesive composition, such as epoxy resin or an adhesive polyurethane composition.
    The intermediate spaces between the support beams 6 and the full-wall panels 4 are occupied by strips 26 (or 27) of thermally insulating material, covering predominantly means of fastening terrains (insulating materials with double casing 1 relative to these strips and means of fastening located in between the weighted spaces between the full-wall panels (Figures 4, 5, and 6),
    Corresponding gaskets between the various elements (support beams 5.6 and adjacent panels) are covered with a backfill strip 28 of the same laminate as sheets 29, 30 and 31, which makes it possible to create a continuous coating 3 that is thermally and mechanically resistant and impermeable to fluids forming the first septum. Sheets 31 and 29 continue, respectively, in the form of 32 and 33 between those lateral sides of the supporting beams 5 and 6, respectively, between which the corner gasket 8 is glued and glued. In addition, the filling substance is placed in positions 34 and 35 between the corner pro- laying 8 and patch strip 26 so that pa the level of the dihedral angle 7 first partition
    3 would have a uniformly rounded shape, without corners and folds.
    The girders, for example, 5 and 6, are also located at the level of the gating sleeves 22 and 23 on supporting means rigidly connected to the pins, for example, 13 and 14, and these supporting means are washers 36 and 37 screwed on These studs are at their specific height, which allows you to pre-determine the exact end position of the mob support beams of any other thermally insulating element) and determine the exact boundary for the gradual disintegration of the filling substance forming the final layer 19 during installation. heat insulating elements.
    In FIG. 2, the recesses 38-41 of the support beams 5 and 6. are presented without gating sleeves that close them, which allows you to see the KOHUJJI studs 42 for the recess 40. This figure shows the method of fastening the panels 43.4 and 44 that are attached to wall 1 using studs 45-48 in the same way as for studs 18 and 14 of the supporting beams 5 and b of figure 1. The panels provided in spaces 49 and 50 are not shown in FIG. 2 to show the type of gasket between support beams arranged in extension — one another, / i.e. between support beams 5 and 51. on the one hand, and support beams 6 and 52 on the other. Note that the gasket between the support beams 5 and 51 has a film of thermally insulating and adhesive substance 53 located between the side of the bobbin and the ends of the said support beams, and these sides are oblique relative to the self-shedding wall. This substance, in particular, is a thixotropic glue or mastic with equivalent properties. TaKiiM can be increased with respect to the gasket, which would be perpendicular to the self-supporting wall, the area of bonding of the supporting beams, as well as stasis. wind the gasket to work on the cut. The skew is 30-45 with respect to the surface of the self-supporting wall 1.

    In the embodiment of drying the composite wall (Figures 4-6), the self-weaving of the wall 1, the layer of thermoisolating elements 2, and the floor 3 of the laminated material forming the first partition presented here are represented. the elements are elements of the wall itself or panels 66 and 67, wherein Pozdudi 19 denotes a layer of a filling substance lying between said panels and a self-supporting wall 1, each panel 66 has a housing with 68 of porous plastic, for example foam-foam liJiH polyurethane medium-density polyurethane, plywood or laminated plate 69 on the side of the housing that faces the self-supporting wall 1, and a sheet 70 of flexible laminate, meccically strong and cold-resistant, on the inner side of the housing 68, and this layer The pre-fabricated material is predominantly the one described in FIG. The edges of the plate 69, for example the edges 7 and 72 (Fig. 4) 5, extend beyond the sides of the housing 68 and are located on supporting means, which are metal washers 73, which are screwed onto a series of studs 74, Placed at the same distance from each other, flat metal washers 75 are positioned between the inner surface of the edges 71 of the adjacent panels and fixed with nuts 76, p: blocked or locked with adhesive to the nut and stud before closing. Arranged obliquely and in opposite directions, the lateral sides of adjacent panels 66 and 67 define a gasket or prostuctal space 77, occupied by a strip 56 of thermally insulating material, which may be the same material from which the enclosures of panels 66 and 67 are made. , one
    hermetically bonded to the oblique sides of the named ianels using an adhesive composition, such as epoxy glue or polyurethane glue, an overlay strip of the same ayuistoy material as the sheets 70, covering the insulating body 68, is glued to the inner surface of the cord 56 and the opposite edges of the cover sheets of the panels 66 and 67,
    which guarantees the tightness of the first partition.
    The lia of FIG. 5 shows that the strip 56 can be a prefabricated part that has already been shaped and which is enough to be placed in the intermediate space 77 between the panels 66 and 67 already provided with sheets of coating . for example 70. When introduced into the intermediate space 77, the strip 56 is not covered with any sheet of laminated material; on the contrary, a similar patch strip, for example 78 (see ST-A), is applied later to ensure that the insulation is required for the insulation layer, the sides 79 and 80 strips 56, intended for contiguous-1H with the sides 81 and 82 of panels 66 and 67, are impregnated with epoxy glue,
    In Fig. 6 (another installation of the strip 56) between the panels 66 and 67, polyurethane foam is fed under pressure, which is then left to harden, the upper side of the pressurized mass is then leveled by. the level of coating 3 (in accordance with the preferred embodiment, the layer is temporarily placed at the said level so that this alignment is not necessary), then strip 56 on the strip 56 and on the edge of the sheets; Although the tightness between panels 66 and 67 is sufficient, you can pre-soak the sides of the 81 and 82 panels before applying pressure.
    66 and 67, respectively, with an adhesive composition that forms an aperture paint of a predominantly elastomeric type, for example, the adhesive of a composition based on a polyurethane elastomer, In the case where the body of the panels 66 and
    67 and the strip 56 is made of urethane foam, a similar adhesive can be applied by brush for several hours before the injection of polyurethane foam under pressure, thus increasing the adhesion between the panels and the cord of porous material supplied under pressure.
    IfeKOTopoe the number of dimensional characteristics of the composite wall, a part of which is represented in Fig. A: .150 cm (and another size of rectangular panels 66 and 67 is, for example, about 300 cm); g 2-4 cm d 20-25 cm; e 0.6-1 cm; f 0.5 2 cm; E 7-15 cm.
    According to FIG. 7, the panels of the wall itself are connected with the displacement of one row of panels relative to another. The rectangular contours 83 of the panels 8A-97 are made to protect the elastomeric film placed on the sheets of the laminated material of the various panels in the sheets, in which case the material of the underlying sheets of the coating does not have an inner layer of elastomer, but only the outer layer of glass fiber The intermediate metallic and outer layers are also made of fiberglass. These sheets of elastomeric film are not located to the extreme edges of the panels, as is the case with sheets 70 (Fig. 6) of laminated material, so that the edges of Morjm patch strips 78 would be attached directly to the edges of sheets 70 of the laminated coating. cover the elastomeric film without danger. After applying the above-mentioned patch strips of the same cnpHC of that material, an elastomer composition is applied to the peripheral edges of the sheets of the elastomeric film of the panels, ensuring the continuity of the film on the entire inner surface of the layer of insulating elements.
    Another arrangement of the panels of the wall itself is to arrange them in parallel rows without displacement in such a way that each strip between two panels of one row is in continuation of the strip between panels of the other rows.
    In the structure of the gasket of Fig. 8, where, for clarity of the drawing, the image of the fastening means of the insulating Elements is omitted, the intermediate space between the panels 93 and 94 is filled in its outer part with parallel edges with porous foam 95 supplied under pressure to provide we have maximum tightness, and in. its internal parts are with oblique edges directed in opposite directions, glued with a trapezoidal cross section, providing maximum mechanical strength.
    In the embodiment of FIG. 9, interstitial clearance 96, located in the outer part of the gasket between panels 97 and 98, is filled with a porous &neiiOiijjacTOM; supplied under pressure at the location, while the inner parts that are parallel to each other, the lateral sides of the above-mentioned sklengzg-me panels, “are attached with the help of the adhesive compound 99.

    Easy installation and material savings due to the low density of the hardened and expanded filling material that fills the space between the external self-supporting wall and the layer of thermally insulating elements, automatic replenishment of errors and surface irregularities outside the self-supporting wall, i.e., local changes the thickness of the space between this wall and the layer of thermoisolation elements, the possible elimination of gotita for the distribution of 5 drops, mainly from plywood, which is usually located on the outside thermal insulation of the elements. {
    Molecularity does not use specific means of fastening the layer of heat-insulating elements to the external self-supporting wall (for example, studs) due to the increase in the adhesion surface and the quality of this adhesion, which is a result of the expansion of the substance in the whole space between the self-supporting wall and layer of thermo-diffusing elements.
    Weaker tensions (in particular, when stretched at the level of thermo-insulating elements) in the case of deformed, self-supporting wall (for example, deformation of the ship’s hull1 as a result of a constant stop of the thermally insulating elements into the hardened and expanded material and better adherence to stresses of any origin due to the fact that the hardened and expanded material has some degree of liquefaction, for example, about 6%, in the case of expanded EPOXY resin.
