Description
Technical field
The present invention relates to a kind of combined type exhaust uptake, particularly residential building smoke evacuation, extract duct and fire-fighting ventilating duct belong to building material field.
Background technology
Be used for the exhaust duct of air conditioner ventilation pipeline, fire-fighting smoke evacuation system in the construction work now and the smoke discharging pipe of house kitchen is basically all used steel plate type flue and concrete prefabricated flue; The former cost is high; Anticorrosion, fireproof performance is poor, construction is inconvenient, is 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 Ministry of Construction and the national standard " house kitchen, washroom exhaust duct JGT194-2006 " of National Development and Reform Committee's promulgation and the requirement of " glass fiber reinforced cement extract duct JCT854-2008 " basically, and when the breaking out of fire of kitchen, cement flue burning easily comes off; Kitchen to having fitted up can cause heavy damage, and 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 rectangle ventilating duct " by name; It by four independently the unorganic glass steel composite board be spliced into the rectangle ventilating duct; The interior angle of its jointing positions has " L " type splice to support, and the exterior angle of jointing positions has glass cloth 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 exhaust system and fire-fighting smoke evacuation system through flange; And back-flow preventer is not set in the ventilating duct, and the splice that is " L " type needs die casting, makes troubles for production and construction.2009 the 5 about 20 days disclosed another kinds of State Patent Office are called the utility model patent (notification number: CN 201241458Y) of " combined type ventilating duct "; It comprises that not firing plate is substrate pipeline of forming and the fixed strip of being located in the pipeline; Fixed strip is arranged at the angle of adjacent substrate, and bonding or riveted is connected between fixed strip and adjacent substrate.This ventilating duct does not have back-flow preventer yet; And being connected between fixed strip and substrate only through a kind of mode in bonding or the riveted; And glass cloth is not wrapped up at the exterior angle; The intensity of pipeline will be had a greatly reduced quality, and is running into the potential danger that exists pipeline to disintegrate under the situation that gas tank or gas explosion manifold pressure increase suddenly.Utility model patent (the notification number: CN 2346871Y) of disclosed another kind on November 3rd, 1999 " house kitchen exhaust uptake " by name; It discloses a kind of hole that is provided with down to get rid of the house kitchen exhaust uptake of coal gas in the kitchen, mainly contains tube wall, fuse plate, goes up the compositions such as exhaust plant on hole and roof.This utility model tube wall and fuse plate adopt the M25 high strength cement mortar, and 10 millimeters glass cloth of central folder are made into integration, and the material refractoriness is poor; And offer two holes up and down, manifold pressure is excessive when meeting big fire, and flue gas very easily pours in down a chimney; And the overheated easy avalanche of pipeline, punch just means and has just increased the chance that flue gas recharges more, has also increased potential risks; Compare with single hole flue, the suction force of flue gas has been reduced half the, and the following hole of offering is unfavorable for the finishing in kitchen; And cause the passage of hole smoke discharging too short, to the suction force decline of flue gas.And back-flow preventer is not all designed in the hole up and down.
Summary of the invention
The present invention provides a kind of combined type exhaust uptake for solving the aforementioned problems in the prior.
Technical scheme of the present invention is following:
1, a kind of combined type exhaust uptake is made up of flue collector, component for variable-pressure, honeycomb duct, and component for variable-pressure and honeycomb duct are fixed in the flue collector, it is characterized in that: it is that substrate constitutes that flue collector does not fire plate by four.
2, connect through riveted between the adjacent two substrates of said flue collector.
3, be connected with riveted through bonding between the adjacent two substrates of said flue collector.
4, said flue collector cross section is rectangle or square.
5, said honeycomb duct is made up of arbitrary face and one to three dividing plate of flue collector, and with less than 60 degree angle shutoff, honeycomb duct is positioned on the substrate on component for variable-pressure opposite with baffle plate in the bottom.
6, said honeycomb duct outlet is in sustained height with the lower end of component for variable-pressure vertical plane.
7, the cross section of said honeycomb duct be rectangle, square, triangle or trapezoidal in any one.
8, leave hole on the common face of said flue collector lower end and honeycomb duct, honeycomb duct is communicated with user's smoke exhaust ventilator pipeline, there is the device that prevents smoke backflow at the hole place.
9, bonding one or more layers glass cloth in the exterior angle of the flue collector of said combined type exhaust uptake and honeycomb duct.
The present invention has reached several effects: than the CN 201241458Y technical scheme of having announced; The substrate that constitutes flue collector and honeycomb duct is not for firing plate; Substitute the traditional cement goods, improved fire-resistant coefficient, and do not fire plate and be connected with the riveted dual mode through bonding; Glass cloth is wrapped up at the exterior angle, has strengthened the anti-pressure ability of pipeline.Second the present invention is provided with component for variable-pressure in flue collector, be provided with anti-flue gas reflux at the hole place, thoroughly solves smoke backflow.
