Abstract
The utility model relates to a combined ventilation duct, and relates to a ventilation device. The ventilation duct is characterized in that: the ventilation duct is of a combined structure, and a flange is formed by butting and bonding profiles with L-shaped cross sections; and a square duct is formed by butting and splicing a plurality of glass fiber reinforced composite material duct boardings, and corner reinforcing ribs are arranged at the corners of the square duct and are fastened by bolts to form the combined ventilation duct. The integrated duct is divided into plates, strip profiles and several components, a mold and the process technology are simplified, and the processing difficulty is reduced; and the plates and strip profiles with different specifications can be produced according to different duct diameters, the combined ventilation duct is assembled in a construction site, and the manufacturing cost of the mold is reduced. The combined ventilation duct has the advantages of simpleness and easy implementation in processing and manufacture, flexible model selection, low production cost, convenience in transportation and the like.
Description
Technical field
The utility model relates to a kind of ventilation equipment.
Background technology
At present, the blower ventilation pipeline mostly is structure as a whole, all time processing moulding in mould of pipeline and flange, the problem that exists is the processing technology complexity, technical difficulty height, particular manufacturing craft complex structure, the cost of manufacture height, a mold can only be produced a kind of ventilating duct, narrow application range.The moulding pipeline takes up room greatly, and transportation is inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of combined type ventilating duct, to solve prior art processing technology complexity, the technical difficulty height, the particular manufacturing craft complex structure, the cost of manufacture height, a mold can only be produced a kind of ventilating duct, narrow application range, the moulding pipeline takes up room greatly, problems such as transportation inconvenience.
The utility model mainly is made up of pipeline, flange, solving the technical scheme that its technical problem adopts is that ventilating duct is a fabricated structure, it is that the butt joint of " L " shape structural shape is bonding that flange adopts the cross section, square pipe is by some glass fiber reinforced plastics composite material pipeline coaming plate butt joint amalgamations, square pipe interior angle place is provided with the turning reinforcing rib, by bolt tightening; Square pipe and flange are bonding by resin glue, and screw bolt reinforcing constitutes the combined type ventilating duct.
Adopting good effect of the present utility model is that the integral type pipeline is decomposed into sheet material and several ingredients of strip section, mould and processing technology have been simplified, reduced difficulty of processing, can produce the sheet material and the strip section of different size according to different tube diameters, the job site assembling has reduced the Mold Making expense, it is simple and easy to do to have processing and fabricating, type selecting is flexible, and cost of production is low, is convenient to advantages such as transportation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model vertical views;
1 flange, 2 bolts, 3 pipeline coaming plates, 4 turning reinforcing ribs, 5 square pipes among the figure.
The specific embodiment
As shown in the figure; Ventilating duct adopts glass fiber reinforced plastics composite material to make fabricated structure, it is that the butt joint of " L " shape structural shape is bonding that flange 1 adopts the cross section, square pipe 5 is by the 3 butt joint amalgamations of four blocks of glass fiber reinforced plastics composite material pipeline coaming plates, and square pipe 5 interior angle places are provided with turning reinforcing rib 4, tighten up by bolt 2; Square pipe 5 is bonding by resin glue with flange 1, and bolt 2 is reinforced, and constitutes the combined type ventilating duct.
