Abstract
The utility model discloses a combined air-exhausting smoke channel. Four non-ignitable plates as base plates (1) are adopted to form a main smoke channel. An auxiliary smoke channel (3) is arranged in a main pipeline. Two adjacent base plates of the main smoke channel and the auxiliary smoke channel are connected in a riveting mode or in a bonding and riveting mode. One arbitrary face of the combined air-exhausting smoke channel and one or three partition boards (4) form the auxiliary smoke channel (3). The section of the auxiliary smoke channel (3) is a rectangle, or a square, or a triangle, or a trapezoid. A hole (5) is reserved in the auxiliary air-exhausting smoke channel which is broken off at the hole. The upper section of the broken-off auxiliary smoke channel is blocked through a baffle (6) at an angle smaller than 90 degrees. One layer or a plurality of layers of glass fiber cloth (2) are arranged on outer angles of the main smoke channel and the auxiliary smoke channel (3) in a sticking mode. A device preventing backflow of smoke is arranged in the hole (5). The combined air-exhausting smoke channel strengthens pressure-resisting capacity of the pipeline, improves construction efficiency, and effectively solves the problem of backflow of the smoke.
Description
Technical field
The utility model relates to a kind of Combined draught flue, and particularly residential building smoke evacuation, extract duct and fire-fighting ventilating duct belong to building material field.
Background technology
Be used for ventilating duct for air-conditioner in the now construction work, the exhaust duct of fire-fighting smoke exhaust system and the smoke discharging pipe of house kitchen are substantially all used steel plate type flue and concrete prefabricated flue, the former cost is high, anticorrosion, fireproof performance is poor, construction is inconvenient, be particularly useful for the concrete prefabricated flue of kitchen and washroom exhaust, it is flexible poor, impact resistance, two important indicators of fire endurance do not reach the national standard " house kitchen of the Ministry of Construction and National Development and Reform Committee's promulgation substantially, toilet exhaust passage JGT194-2006 " and the requirement of " glass fiber reinforced cement extract duct JCT854-2008 ", when the breaking out of fire of kitchen, cement flue easily burning comes off, can cause heavy damage to the kitchen of having fitted up, life property safety of people and public interest are caused very big hidden danger.
May 23 calendar year 2001, State Patent Office disclosed the utility model patent (notification number: CN 2431460Y) of a kind of " a kind of rectangular ventilating duct " by name, it by four independently inorganic glass fiber reinforced plastic composite plate be spliced into rectangular ventilating duct, the interior angle of its splicing place has " L " type splice to support, and the exterior angle of splicing place has glass-fiber-fabric to coat.This product has used FRIM, fire-resistant, withstand voltage can both being up to state standards, but it connects the ventilating duct that is mainly used in large-size air conditioning ventilation wind system and fire-fighting smoke exhaust system by flange, and back-flow preventer is not set in the ventilating duct, the splice that is " L " type needs die casting, makes troubles for production and construction.2009 the 5 about utility model patent (notification numbers: CN 201241458Y) of the disclosed another kind of State Patent Office on the 20th " Combined type ventilating pipeline " by name, it comprises that not firing plate is the substrate pipeline that forms and the fixed strip of being located in the pipeline, fixed strip is arranged at the angle of adjacent substrate, and fixed strip is connected bonding with adjacent substrate or riveted connects.This ventilating duct does not have back-flow preventer yet, and the connection that fixed strip is connected with substrate is only by a kind of mode in bonding or the riveted, and glass-fiber-fabric is not wrapped up at the exterior angle, the intensity of pipeline will be had a greatly reduced quality, and suddenly increases the potential danger that exists pipeline to disintegrate in the situation that run into gas tank or gas explosion manifold pressure.Utility model patent (the notification number: CN 2346871Y) of disclosed another kind on November 3rd, 1999 " kitchen exhaust fume duct " by name, it discloses and a kind ofly has been provided with lower hole to get rid of the kitchen exhaust fume duct of coal gas in the kitchen, mainly contains the compositions such as exhaust plant on tube wall, fuse plate, upper hole and roof.This utility model tube wall and fuse plate adopt the M25 high strength cement mortar, 10 millimeters glass-fiber-fabrics of central folder are made into integration, the material refractoriness is poor, and offer up and down two holes, manifold pressure is excessive when meeting big fire, flue gas very easily pours in down a chimney, and the easy avalanche of pipe overheat, punch just means and has just increased the chance that flue gas recharges more, has also increased potential risks, compares with single hole flue, suction force to flue gas has reduced half, and the lower hole of offering is unfavorable for the finishing in kitchen, and causes the passage of hole smoke discharging too short, and the suction force of flue gas is descended.And back-flow preventer is not all designed in the hole up and down.
Summary of the invention
The utility model provides a kind of Combined draught flue for solving the aforementioned problems in the prior.
The technical solution of the utility model is as follows:
1, a kind of Combined draught flue is characterized in that: adopting four, not fire plate be that substrate consists of flue collector, is provided with auxillary flue in the trunk line.
2, described flue collector is connected with auxillary flue and leads to the riveted connection between two substrates.
3, described flue collector is connected with auxillary flue and is connected with riveted by bonding between two substrates.
4, described flue collector cross section is rectangle or square.
5, described auxillary flue is made of arbitrary face and one to three dividing plate of flue collector.
6, the cross section of described auxillary flue be rectangle, square, triangle or trapezoidal in any one.
7, leave hole on the common face of described Combined draught flue flue collector upper end and auxillary flue, make auxillary flue and user's smoke exhaust ventilator pipeline communication, hole place auxillary flue interrupts, and section usefulness baffle plate is with less than an angle of 90 degrees shutoff on the auxillary flue of interruption.
8, bonding one or more layers glass-fiber-fabric in the exterior angle of the flue collector of described Combined draught flue and auxillary flue, there is the device that prevents smoke backflow at the hole place.
The utility model has reached several effects: than the CN 201241458Y technical scheme of having announced, the substrate that consists of flue collector is connected with the riveted dual mode by bonding, and glass-fiber-fabric is wrapped up at the exterior angle, has strengthened the anti-pressure ability of pipeline.Second the utility model is provided with auxillary flue in flue collector, be equivalent to the chimney of independently bleeding has been installed, and at auxillary flue hole place the flue gas reflux be set, and efficiently solves the problem of smoke backflow, and this also is that the correlation technique scheme does not possess.
