Abstract
The utility model provides a clamping groove-type gas-tight smoke removal air passage with high strength, which relates to the smoke removal air passage used for discharging flue gas and waste gas in kitchens and washrooms in the buildings such as abodes, apartments and the like and is especially used for solving the air leakage problem of the conventional smoke removal air passage with an assembled structure. The clamping groove-type gas-tight smoke removal air passage with high strength is characterized by the inclusion of four fire-resistant light wallboards connected and assembled through clamping grooves; heat-resisting and corrosion-resisting rubber is used for jointing the joints of the clamping grooves; the cross section of the smoke removal air passage is in the shape of a rectangle; and strengthening ribs with circular arc transition are arranged at four corners inside the smoke removal air passage. Compared with the prior art, the clamping groove-type gas-tight smoke removal air passage with high strength has the advantages as follows: firstly, an integral clamping groove-type assembling structure is adopted, and external connecting pieces and adhesive are not needed for connection, so that the stability of finished products can be ensured; secondly, the strength of products is greatly improved, and the smoke removal air passage cannot deform when the four surfaces of the smoke removal air passage are stressed at the same time; and thirdly, the accuracy of the finished products is ensured and the production volume is increased at the same time by virtue of machine work, and the technical requirements on a production worker is also lowered.
Description
Affiliated technical field
The utility model relates to the kitchen in the buildings such as a kind of dwelling house, apartment, a kind of card slot type high strength tightness exhaust gas flue of use in toilet flue gas and waste gas in getting rid of building is especially for the exhaust gas flue that solves present splicing structure exhaust gas flue gas leakage problem.
Background technology
All be provided with exhaust gas flue at present nearly all building and be used to get rid of building interior flue gas and waste gas, closely bound up with common people's daily life.The production technology of existing exhaust gas flue is prefabrication and assembly unit method basically.Prefabrication is the drawing requirement according to building side, installs after being prefabricated into the exhaust gas flue of different size model in advance.Its shortcoming is: need a large amount of production mould and place 1..2. product is too heavy, is inconvenient to transport and install.3. inefficiency can not form production in enormous quantities.And the assembly unit method is according to the exhaust gas flue shape need, through manually assembling, is installed by the shape that bonding agent and carpenter's nail connect into exhaust gas flue by four blocks of side plates.Its shortcoming is: because exhaust gas flue by manually fixing with carpenter's nail, makes the verticality of exhaust gas flue to be guaranteed, thereby do not reach the industry standard of country 1..2. surface bears is not enough.Exhaust duct two sides wherein is gluing by having only side plate thickness to carry out, can not be stressed, not only the transportation and installation process in very easily the damage and also can not reach national sector standard.3. existing market does not also have fire endurance to reach bonding agent and the carpenter's nail of 1h.Because carpenter's nail, the fire endurance of bonding agent is much lower than the fire endurance of side plate, and whole flue is fallen apart, and flue is no longer sealed, lost the smoke evacuation function, consequence is hardly imaginable, and its fire resistance is difficult to reach national sector standard.
Summary of the invention
Cause product can not reach the present situation of national sector standard in order to solve deficiency owing to existing production technology, the utility model provides a kind of in light weight, intensity is high, national sector standard is installed, is fit to produce in enormous quantities and meet in convenient transportation card slot type high strength tightness exhaust gas flue.
The technical scheme that its technical problem that solves the utility model adopts is: connect assembled by four fire-proof light wall-plates by the punch-die on the wallboard after processing, the punch-die of wallboard is to pass through special-purpose molding cutter machine-shaping in cuts sheet material, the back taper structure has been adopted in root cooperation place at punch-die, utilize the elasticity of groove the wallboard that has punch to be sticked in the wallboard that has groove during assembly unit by the even reinforcing of machinery, for the junction, tightness punch-die top that guarantees exhaust gas flue has high temperature resistantly, corrosion resistant rubber is fitted.The exhaust gas flue cross section is rectangular, four jiaos of reinforcing ribs that are equipped with round-corner transition of flue inboard.In addition, under the prerequisite that does not influence the exhaust gas flue functional performance, strengthen the contact surface of reinforcing rib place and wallboard junction, guaranteed the verticality and the structural stability of exhaust gas flue.
Compared with prior art: 1. because the utility model has adopted entire card slot type splicing structure, do not need joint outer part to be connected, so can guarantee the stability of finished product with bonding agent; 2. the intensity of product is greatly improved, and can guarantee that the four sides is simultaneously stressed and can not be out of shape.3. utilize machining, also improved output when having guaranteed finished product accuracy, also reduced technical requirements the direct labor.4. the main material of fire-proof light wall-plate is that magnesia, fiberglass gridding cloth and gauze wire cloth are formed, and makes the intensity of finished product and fire resistance be guaranteed, and meets national sector standard; 5. owing to adopted fire-proof light wall-plate, made things convenient for the transportation of exhaust gas flue to install.

The specific embodiment
As shown in the figure, the utility model is assembled by two blocks of assembly unit plates 1 and two blocks of assembly unit plates 2, and assembly unit plate 1 and assembly unit plate 2 are in cuts sheet material, by the machine-shaping of MU molding cutter, adopted the back taper structure at the punch-die root.When assembly unit, in assembly unit plate 1 groove, spread high temperature resistant, the corrosion resistant rubber 3 of one deck earlier, place assembly unit plate 1 and assembly unit plate 2 by special fixture then, utilize the elastic deformation of assembly unit plate 1 groove to make assembly unit plate 1 and 2 cooperatively interact by the even reinforcing of machinery, and utilize the elasticity of rubber 3 and the back taper of punch-die cooperation place, make the tightness of finished product be guaranteed.In addition, under the prerequisite that does not influence the exhaust gas flue functional performance, strengthen the contact surface of reinforcing rib place and wallboard junction, guaranteed the verticality and the structural stability of exhaust gas flue.The cross section of exhaust gas flue is rectangular.
