Particularly, described cover plate 200 is spliced by least two scabs, so that the manufacture moulding of cover plate 200, the quantity of scab can arrange flexibly according to actual conditions.Additionally, cover plate 200 also can adopt integrated structure, all belongs to protection scope of the present invention.
Further, the sidewall that at least described stack body 100 offers through hole 101 is provided with slurry curing overlapping layers 300, slurry curing overlapping layers 300 is covered on the sidewall that stack body 100 offers through hole 101 or is covered on other sidewall of stack body 100 simultaneously, with the sidewall that offers through hole 101 with stack body 100, form double side walls, reliability is good.In the present embodiment, it is raw material that slurry curing overlapping layers 300 adopts slurry, be applied in and the sidewall of cover plate 200 be installed on stack body 100 and solidify to form slurry curing overlapping layers 300, with securing cover plate 200 better, make cover plate 200 can be fixed on more reliably the sidewall of stack body 100, further improved the sealing performance of structure.
Further, described slurry curing overlapping layers 300 lateral walls are provided with sheet material, and described sheet material is bonded in described slurry curing overlapping layers 300 lateral walls.Sheet material can be ceramic tile etc., has further guaranteed sealing and the intensity of structure, and can make stack body 100 elegant in appearance, and sheet material, slurry curing overlapping layers 300 form three layers of sidewall with stack body 100, and reliability is good.
Particularly, cover plate 200 is spliced by least two scab (not shown)s, so that adjust air inlet port 201 position in larger scope, the quantity of scab can arrange flexibly according to actual conditions.Additionally, cover plate 200 also can adopt integrated structure, all belongs to protection scope of the present invention.
Further, cover plate 200 is provided with the guide pipe 210 that is connected with air inlet port 201 and surrounds air inlet port 201, and guide pipe 210 can be fixed on cover plate 200 inner sides by fixture, also can be shaped in cover plate 200 inner sides.Guide pipe 210 surrounds air inlet port 201, be beneficial to exhaust, and by guide strip being located to cover plate 200 inner sides, then cover plate 200 is fixed on to the sidewall of air inlet pipe in the construction later stage, can prevent that building waste drops and stops up guide pipe 210 and air inlet port 201 in work progress, structural reliability is good.And guide pipe 210 is fixed on cover plate 200 inner sides, relative position between guide pipe 210 and air inlet port 201 is fixed, when air inlet port 201 position is adjusted, guide pipe 210 still can work reliably, avoid exhaust pipe structure of the prior art because adjusting air inlet port 201 positions, to destroy the deficiency of guide pipe 210, also avoided dropping in installation process the bad phenomenon that building waste in pipeline is stuck in guide pipe 210 blocking pipes simultaneously, effectively guaranteed that the system after extract duct is installed is used function.
Further, on cover plate 200, be installed with venturi plate 220, venturi plate 220 be right against air inlet port 201 and and cover plate 200 surround and form between the functional areas of cross-sectional area that cross sectional area is less than stack body 100.Venturi plate 220 can be fixed on cover plate 200 by locking member, also can be shaped on cover plate 200.According to Venturi effect, negative pressure is accelerated and formed herein to gas flow velocity when the sectional area by less, avoid gas in stack body 100 to flow backward to the gas in ，Qie Keshi room in room from air inlet port 201 and accelerate to discharge from stack body 100, exhaust effect is good.And by venturi plate 220 plates are located to cover plate 200 inner sides, then cover plate 200 is fixed on to the sidewall of air inlet pipe in the construction later stage, can prevents that building waste drops and stops up air inlet port 201 in work progress, structural reliability is good.And venturi plate 220 is fixed on cover plate 200 inner sides, the relative position between venturi plate 220 and air inlet port 201 is fixed, and when air inlet port 201 position is adjusted, venturi plate 220 still can work reliably.
Further, on described cover plate 200, be provided with at least one for the suspension member 231 of fixing fire prevention cover plate 232.Suspension member 231 is hook-shaped, to connect fire prevention cover plate 232 by fuse link.Fuse link can fuse at a certain temperature automatically, with the cover plate 232 of preventing fires in needs, decontrols, and the cover plate 232 sealing guide pipes 210 that make to prevent fires, to intercept reliably fire spreading.Further, described cover plate 200 outsides are installed with the bulge loop band 230 that is surrounded on described air inlet port 201.So that connection exhaust branch pipe makes sealing reliably between exhaust branch pipe and cover plate 200.
Further, described air inlet port 201 outsides are provided with the base of valve or connecting hose, so that the connection of exhaust hose.
A kind of exhaust pipe structure that the embodiment of the present invention provides, its installation process is as follows: first at factory or solution space difference moulding arranging tracheae body 100 and cover plate 200, now on stack body 100, offer most the through holes 101 that are greater than cover plate 200 sizes, the quantity of through hole 101 is corresponding with the quantity of cover plate 200, and concrete quantity can be according to actual conditions setting.On cover plate 200, offer air inlet port 201, air inlet port 201 is provided with bulge loop band 230 around.Again stack body 100 and cover plate 200 are transported to job site, and stack body 100 is mounted on building.Cover plate 200 is positioned in through hole 101 again, and utilizes the gap adjusting cap Ban200 position between through hole 101 and cover plate 200 according to actual conditions, make air inlet port 201 position meet site operation requirement, air inlet port 201 position is adjusted very convenient.Again slurry is filled in to the gap between cover plate 200 and through hole 101, treats that slurry curing just can be integrated bonded on stack body 100 by cover plate 200, simultaneously shutoff the gap between cover plate 200 and through hole 101.Like this, can adopt in advance half-finished stack body 100 is installed, when building construction completes substantially, the construction later stage is fixed on cover plate 200 through hole 101 places on stack body 100 again, the rubbish of avoiding falling in stack body 100 is stuck in guide pipe 210 or venturi plate 220 places, and reliability is good, then adopting slurry is raw material, be applied in the sidewall formation slurry curing overlapping layers 300 that stack body 100 is provided with cover plate 200, slurry curing overlapping layers 300 is covered in the sidewall of cover plate 200 and stack body 100, sheet material again bonds on slurry curing overlapping layers 300, as ceramic tile etc., finally exhaust hose is connected to air inlet port 201, construct very convenient, solve existing exhaust pipe structure and because adjusting air inlet port 201 positions, destroyed the deficiency of guide pipe 210, air inlet port 201 positions are adjusted very convenient, also solved in installation process simultaneously, the building waste dropping in pipeline is stuck in guide pipe 210 positions, blocking pipe phenomenon, effectively guaranteed the system functional performance after extract duct is installed.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
