Abstract

The utility model discloses a combined exhaust passage which is characterized in that the combined exhaust passage is composed of a plurality of exhaust passage units, one exhaust passage unit comprises an outer frame (1) and two inner molds (2), the outer frame is composed of four long plates, the inner mold (2) at one end of the outer frame (1) is higher than the outer frame to form a son opening (3), the inner mold (2) at the other end of the outer frame (1) is located inside to form a mother opening (4), the son opening (3) of one exhaust passage unit is connected with the mother opening (4) of the other exhaust passage unit, seams are filled with cement mortar, and the complete exhaust passage is formed after the circulation. Due to the insert principle, the combined exhaust passage is simple in manufacturing, convenient to mount and high in safety coefficient, an industrial standard can be formed easily, and the combined exhaust passage can be produced and used in large scale. The combined exhaust passage has the advantages that air leakage of connecting seams is prevented, cracking is avoided, and cracks can be easily filled; a single exhaust passage unit can be conveniently produced, transported, stored and mounted.

Description

Combination type exhausting channel

Technical field

The utility model belongs to technical field of buildings, relates in particular to a kind of combination type exhausting channel of the kitchen guarding's of building smoke discharging waste gas.

Background technology

Exhaust duct is in order to get rid of flue gas or the waste gas of kitchen, washroom, and nearly all building is all provided with exhaust duct.Existing exhaust duct is substantially cut or is formed with cement pouring by on-the-spot block of ordinary Portland cement material, or prefabricated forming, and wherein on-the-spotly builds that to cut be a kind of comparatively traditional method, and along with modernization, the standardization of Building technology, the method is no longer used substantially.Commonplace use be prefabricated method, according to the requirement of different buildings, be prefabricated in advance the exhaust duct of different size model, then exhaust duct being transported to scene installs, the shortcoming of its existence is: 1, because the specifications and models of exhaust duct are more, therefore need to make a large amount of production moulds, 2, production scene at prefabricated exhaust passage for carrying away needs larger production site, 3, because exhaust duct is mainly to be made by cement yellow sand material, therefore the weight of its finished product is larger, install and very inconvenience of transportation, 4, intensity is lower, producing, fragile in the process of transportation and installation, its intensity is difficult to reach national sector standard, 5, production efficiency is low, be difficult to form and produce in enormous quantities, 6, due to rough inner surface, after using a period of time, easily deposit greasy dirt and affect exhaust effect., there are some exhaust ducts on existing market in the problem existing in order to solve above-mentioned exhaust duct, four jiaos that in exhaust duct, survey are provided with the reinforcing rib that connects adjacent panel having.This exhaust duct has solved Heavy Weight in prior art, inconvenience is installed in transportation, and the while has also solved production mould and production site is manufactured the problem inconvenient, yield rate is low.But still have complex manufacturing technology at the reinforcing rib that connects adjacent side plates, production efficiency is not high, and intensity is not high, and the problem such as processing cost height.

Chinese patent 2010202488750 discloses a kind of < < for the light combined exhausting channel > > of kitchen and washroom exhaust, between the plate of two opposite sides, establishes reinforcing rib; Chinese patent 2009201857219 discloses a kind of < < combined inner mold formula fireproof kitchen-toilet exhaust passage > >, is in housing, to be distributed with several internal molds to strengthen intensity.All solved the problem of intensity, still, can not Fast Installation, gas leakage or exist, can not guarantee the problem of verticality, insecure, poor stability.When particularly execution conditions do not meet whole exhaust duct and install at the scene, exhaust duct need be divided into two sections while docking up and down, when stream pressure is excessive in exhaust duct, often at butt joint place, easily ftractures, leak gas; Or in two sections of upper and lower docking operations of exhaust duct, do not have entirely on the centerly and vertical, cause exhaust duct wall unbalance stress, the exhaust duct phenomenon such as break.

Summary of the invention

The purpose of this utility model is to provide a kind of combination type exhausting channel, and this exhaust duct is light and handy, makes simply, installs fast, air tight, guaranteed strength and verticality, and firmly, good stability, can enhance productivity.

The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions: a kind of combination type exhausting channel, by a plurality of exhaust ducts unit, formed, one of them exhaust duct unit comprises housing and two internal molds that are comprised of four block length plates, it is characterized in that, one end internal mold of housing, higher than housing, forms rim of the mouth; The other end internal mold of housing, interior, forms female mouthful; The rim of the mouth of an exhaust duct unit is connected with female mouth of another exhaust duct unit, by cement mortar, squeegees, and so circulation just forms a complete exhaust duct.

The internal mold in described rim of the mouth exceeds housing 1.5-2cm; The internal mold of female mouthful puts in housing 2cm.

The utility model compared with prior art has obvious advantage and beneficial effect.From above technical scheme, the utility model utilize plug-in unit principle make simple, easy for installation, safety factor is high, very easily forms industry standard, can scale batch production and use.Internal mold plays skeleton supporting role, gains in strength; The female mouth in rim of the mouth is convenient to install, and has verticality, stability, fastness good.Generally speaking: 1, anti-seam crossing gas leakage; 2, anti-cracking, crack is easily filled up; 3, single exhaust duct unit produces, transports, deposits, installs all and facilitate.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is use state diagram of the present utility model.

Mark in figure:

1, housing; 2, internal mold; 3, rim of the mouth; 4, female mouthful.

The specific embodiment

Below in conjunction with accompanying drawing and preferred embodiment, the combination type exhausting channel specific embodiment, structure, feature and effect thereof to according to the utility model proposes, be described in detail as follows.

Referring to Fig. 1-3, a kind of combination type exhausting channel, is comprised of a plurality of exhaust ducts unit, and one of them exhaust duct unit comprises housing 1 and two internal molds 2 that are comprised of four block length plates, it is characterized in that, one end internal mold 2 of housing 1, higher than housing, forms rim of the mouth 3; The other end internal mold 2 of housing 1, interior, forms female mouthful 4; The rim of the mouth 3 of an exhaust duct unit is connected with female mouth 4 of another exhaust duct unit, by cement mortar, squeegees, and so circulation just forms a complete exhaust duct.

The internal mold 2 in described rim of the mouth 3 exceeds housing 1 1.5-2cm; The internal mold 2 of female mouthful 4 puts in housing 1 2cm.

The utility model internal mold plays skeleton supporting role, gains in strength; The female mouth in rim of the mouth is convenient to install, and has verticality, stability, fastness good.

The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
