Noise-absorbing layers of different-density materials. Said carcass is composed by rectangular parallelepiped with ribs L×H×B related as follows: L:H:B = 2:1:0.5. Every said perforated wall made of structural material with damping coating has holes of round, triangular, square, rhombic profile with diameter of 3-7 mm. Sound-absorbing material can be foam aluminium, cermet, stone of 30-40% porosity or other fibrous of porous mineral materials with binder. Entire surfaces of said sound-absorbing element is lined with acoustically transparent materials, for example, glass fabric of EhZ-100 type or copolymer resin "Poviden". |

Invention relates to construction materials, particularly, to sandwiched carbonate sheets. Extruded polycarbonate sandwiched sheet structure comprises at least two, or seven or more, in fact parallel spaced apart walls and multiple ribs extending over sheet length in direction of extrusion to separate adjacent walls. Said sheet structure features total height over 40 mm while polycarbonate has melt viscosity factor over 4.5 measured at 260°C making the ratio between viscosity at shear ratio of 0.1 c-1 and that at 100 c-1. |

Anti-icing device is made in the form of a cover from neoprene rubber, which is attached to an icy surface and inside which rubber tubes are arranged, which are connected to a compressed air source. Stiff membranes are installed inside the tubes, and the compressed air source is provided with a control system including controls for pressure and frequency of periodic air supply; with that, frequency values for each section of the device between the membranes by means of feedback sensors are capable of being automatically set for natural oscillation frequency of the same section, which varies depending on destruction degree of the ice formed in it. |

Vertical cylindrical tank for storage of liquids and gases In a vertical cylindrical tank including a roof, a vertical wall, a pile foundation with an annular grillage, a flat bottom and a system of flexible elements, behind the vertical wall there located are spatial columns built on broadenings of the annular grillage. A structural covering is installed above the columns. As flexible elements tension bars with adjustable length are used, which are connected to the tank bottom by means of hinges, located with the specified pitch in a plan view and pass through tight guides arranged in the tank roof. |

Single-layer net vault with double curvature Single-layer net vault with double curvature consists of arches of two cross directions collected from the bearing cores and forming quadrangular cells with connection assemblies and contour elements. Arches of the first direction with the central arch are made from the bearing cores connected among themselves by the first gusset plates, arches of the cross direction with the central arch are made from the bearing cores connected among themselves by the second gusset plates. Arches of the first and cross directions, except for the central arches, are fitted on the ends with the first and second gusset plates respectively. The central arches are fitted on the ends with the third gusset plates. The first and second gusset plates are implemented as rectangular plates with the cuts vertically located in the centre, and cuts of the first and second gusset plates are directed towards to each other for formation of assembly of connection at connection of arches of the first and cross directions, and contour elements are made as the perimeter cores connected to end gusset plates of arches. |

Joint connection of rod elements in spatial structure Joint connection comprises a connecting element in the form of a cylinder with dimensions providing for joining of the necessary quantity of rod elements. Rod elements are connected with a cylinder with the help of angles, in which one shelf is straight, and the other one is bent along the radius of cylinder curvature. |

Tent for public training in emergency situation environment Tent for public training in an emergency situation environment comprises a fabric tent which forms a cover, side walls and end walls with an entrance opening, a floor and an internal dismountable frame consisting of multiple sections, each consisting of cross bars and connecting arcs with side outlets. The sections are connected by longitudinal bars which are fixed in the side outlets of the connecting arcs. The cross bars of the frame are inserted by their lower ends into sockets on the floor of the tent to fix the frame. The walls of the tent have windows and/or ventilation holes. The cover has a hole for a smoke pipe. The material of the fabric tent used is a material which reflects infrared radiation and contains a textile base, a metal-coated layer and a microporous membrane layer. The textile base used is a polyester textile material. The metal-coated layer is titanium nitride, and the microporous membrane layer is made of a thermoplastic polyurethane resin and is placed between the textile base and the metal-coated layer. The polyester textile material is soaked with cement slurry. The tent is provided with at least one additional layer of fabric material which is mounted outside the fabric tent and soaked with a consistency based on liquid polyurethane with addition of a mixture consisting of equal portions of ground glass bits, mica and lead crumbs or shavings. |

Roof cornice, providing for automatic icicles drop under wind gusts, comprises a metal rope parallel to the wall and tightened with the help of elastic plates at the sides of the building with a property of windage. On the rope there is a U-shaped metal bracket fixed vertically, the upper side of which is placed under the cornice in the zone of icicles formation. Inside the bracket there is an angle fixed, formed by two orthogonal wind-driven plates arranged in the horizontal plane between the rope and the wall and in the vertical plane below the rope at its side opposite to the bracket. |

Partially prefabricated building and method of its erection Invention relates to erection of prefabricated construction structures. Proposed process comprises the steps that follow. Concreting the floor (3) on soil (2). Hoisting means (4) are installed at floor (2), at corners of roof (3). Walls (1) and roof (3) are moulded at floor (2) at fitting at floor (2) of walls form (30) and roof form (31). After assembly of forms (30, 31) the latter are filled with concrete to be hardened. Note here that walls (1) and roof (3) are connected by connector (7) that makes semi-stiff connections there between. Roof (3) and walls (1) are hoisted simultaneously by said hoisting means (4) provided with fixed part (8) arranged at floor (2) and moving part (9) displacing relative to the latter and connected with roof (3). Walls (1) and roof (3) are simultaneously hoisted and turned and displaced relative to bottom edge from initial position whereat walls (1) and roof (3) rest on floor (2) to final position owing to the weight of walls and said semi-stiff connection (7). Note here that roof (3) and walls (1) are hoisted with the help of beams (32) arranged parallel with the sides of roof (3), nearby its ends. Note also that beams (32) are equipped with extending bars (34) at the ends of beams (32) to be pushed off by second discs (13) secured to hoisting means moving parts (9). Walls (1) are bundled and bonded together. Walls (1) are bonded with roof (3) and hoisting means (4) is removed. |

Invention relates to suspended ceilings, in particular, to improvement of components of T-shaped profiles used to erect a metal frame of such ceilings. A frame runner with a vertical partition, with at least one slot of a transverse runner, in which the partition is irreversibly deformed on a local area, which adjoins the slot of the transverse runner for changing the rated thickness of the partition at the specified local adjacent area compared to its actual thickness on a larger area of the partition, when this local area engages with the end connector of the runner, which determines adjacency of the runner partition between a pair of opposite identical coupled connectors of transverse runners closed in the slot. Also a frame system of a suspended ceiling and the method to produce good adjacency between frame runners and end connectors of the transverse runner are described. |
