The invention relates to the field of construction, namely, the construction of sections of chutes for removing waste from buildings, but can also be used as the team section of the ventilation shaft of a building or structure.

Well-known section of the barrel of rubbish, made in the form of a three-layer pipe, the inner and outer layers are made of a steel material and an intermediate layer made of impact-resistant non-flammable teplocomunenergo material, which can be applied claydite-concrete (patent RU No. 34589 U1, IPC E04F 17/10, 2003).

The disadvantage of this design is the large complexity of manufacture, due to the necessity of using special tooling for centering the outer and inner layers, as well as the high cost and weight of the structure.

A known design of rubbish a multi-storey building, designed in the form of a stem, consisting of the inner lining of corrosion-resistant metal and the outer shell in the form of segments made of lightweight concrete or brick laid in a row on the edge relative to the inner shell (patent RU №2129641, IPC E04F 17/10, 1999).

The disadvantage of this design is the large mass of the structure, the high complexity of manufacturing and installation, as well as low zvukot Asia because of the presence of sound bridges due to the close contact of the outer to inner layers.

Known chute containing the pipeline in the form of elements, interconnected by fasteners in the form of brackets and flexible links. Each element is designed as mounted coaxial conical shell and the outer shell is made of metal inelastic material, and the inner shell is made of elastic sound-absorbing material, for example rubber (patent RU №2225927, IPC E04F 17/12, 2004).

The disadvantage of this chute is the complexity of manufacturing and navigational, due to the low internal resistance of the rubber shell and arise because of different impulses and delaminations, leading to buildup on the inside of shell debris.

Known trunk section of the chute, made of fiberglass and in cross section having a circular cylindrical, or elliptical, or rectangular shape, with the stem of these sections should be covered teplozvukoizolirujushchej material (patent RU №2098575 C1 IPC E04F 17/10, 1997).

The disadvantages of this invention are the high complexity of the installation of the barrel garbage teplozvukoizolyatsia material, as well as its low strength, because of teplozvukoizolirujushchej of materials which deform themselves with a small radius of curvature, you can use only a soft fibrous material is in, stratified during their deformation. When this standard teplozvukoizolirujushchej-type material ISOVER, ROCKWOOL, URSA, made of fiberglass soaked in flammable and environmentally harmful phenolic resins.

The closest technical solution known is the trunk section of the chute, made in the form of a pipe with connecting broadening from one end of the layered laminate consisting of multiple layers of glass and/or glass Mat and a combustible binder, deposited between layers of fiberglass (patent RU №2299959, IPC E04F 17/12, 2007). The invention adopted for the prototype.

The disadvantage is the low thermal and sound insulation sections of the chute, as the wall section is made of a dense composite, which transmits the impact noise and vibration when operating the incinerator. Insulating properties of the composite material from which made the session low, which will cause condensation to form on the outer layers and korrodirovaniju the metal parts of the incinerator.

The technical result for the solution of which the present invention is directed, is to increase the structural strength while reducing its weight, and to enhance teplozvukoizolirujushchej properties section of the chute and its durability at the expense of organisms is the removal of condensate liquid.

This technical result is achieved by the fact that in the section of the barrel of rubbish, made in the form of a pipe with connecting broadening from one end of the layered laminate consisting of multiple layers of glass and/or glass Mat and a combustible binder, deposited between layers of glass, between the inner and outer layers of the tube is placed zigzag corrugated filler in contact and connected with their tabs with the above layers due to applied to the fiberglass binder and forming together with the inner and outer layers of the pipe zigzag through the channels. This zigzag corrugated filler is selected in such a way that the through channels formed by the projections of the filler, are located along the pipe axis, and its ends are ring grooves and holes, connected end-to-end channel filler, and provides for the passage and removal of the condensate liquid out of the pipe. Zigzag corrugated filler made of paper and/or cardboard with a density of 120-180 g/m2to which applied waterproof coating, and the paper or cardboard impregnated onebusaway composition.

The main feature of sandwich structures with light fillers is that due to the diversity of bearing the Loew at some distance from each other is achieved by a large ratio of rigidity to weight. If you compare this with a single-layer plate of equal mass, the ratio of stiffness will be at least one to three. For a rational choice of the parameters of the three-layer design, and sufficient strength of the connection is more subtle bearing layers can withstand higher loads.

Given the applicant an analysis of the level of technology has allowed to establish that the analogs are characterized by the sets of characteristics is identical for all features of the claimed technical solution, no. Therefore, the claimed technical solution meets the condition of patentability "novelty".

Search results of known solutions in this field of technology in order to identify characteristics that match the distinctive features from the prototype features of the proposed technical solution, showed that they do not follow explicitly from the prior art. Of certain of applicant's prior art there have been no known impact provided the essential features of the claimed technical solution of transformations on the achievement of the technical result. Therefore, the claimed technical solution meets the condition of patentability "inventive step".

The invention is illustrated by drawings, where figure 1 shows a General view of the section of the trunk of the chute, figure 2 view a in figure 1, figure 3 is a part section b-B of figure 2, figure 4 is a variant of the section of the trunk of the chute spiral zigzag corrugated core.

In figure 1, 2 and 3 numbers denote the following positions: 1 - tube, 2 - inner layer (shell) section 3 - zigzag corrugated filler, 4 - outer layer (shell) section 5 - connecting broadening section 6 - internal plane interface broadening, 7 - groove 8 - connecting openings of the channels 9 through channels placeholder.

The trunk section of the chute is made in the form of a circular cylindrical tube 1 consisting of an inner shell 2, the zigzag corrugated filler 3, the outer shell 4. For mounting the partition in the trunk it is made with broadening 5 at its upper end in the form of a cylindrical socket, the internal diameter than the external diameter of the pipe. On the inner plane of junction 6 ening 5 is made annular groove 7 and the hole 8 connecting the annular groove 5 through channels 9 zigzag corrugated filler 3. In the manufacture of sections of the chute outer shell 4 of the pipe can be obtained by known methods of calculations or winding on the forming tooling layers known brands of fiberglass and impregnated known polymer mixture. Zigzag corrugated for Omnitel 3 is made flat or single curvature by forming on special equipment and in the manufacture of sections of the chute laid on the inner shell so so through the channels 8 of the filler are oriented along the axis of the section of the barrel garbage. The outer shell 4 is made on the surface of the placed filler 3 known ways of laying out or winding-known brands of fiberglass and impregnated known polymer mixture. The internal connection 2 and 4 outer shell with filler 3 is provided a polymeric binder layers of shells. After winding layers of the outer shell blank section utverjdayut according to the technological regulations. Then the workpiece sections to be removed from the mandrel and spend machined to the required dimensions and on the subject of the manufacture of annular grooves 7 and holes 8.

Another option (figure 4 and figure 5) execution of the section of the barrel garbage disposal is implemented by performing a zigzag corrugated filler in the form of a folded design spiral structure. This end-to-end channels remain vertical and coaxial to the axis of the pipe chute. The angle of helix α is determined from the relation α=arctan((2S×Ns)/(π×D)), where 2S is the step between the vertices of the zigzag lines; Ns - number of modules on the zigzag lines in blank; D - inner diameter of the barrel garbage. This form of execution of the filler increases the strength section of the barrel garbage disposal, improves the manufacturability of the design with the save function is condensate from the pipe, as well as heat and sound insulation.
