Description
Technical field
The utility model relates to air shooter technical field more particularly to a kind of double-deck galvanized sheet rectangular air ducts.
Background technique
Air hose is the pipe-line system for air delivery and distribution.There are composite air duct and two kinds of inorganic air hose.It can be by section
Shape and material classification.Air hose production is that sealant is coated at the gaps such as seaming seam, riveted seam, flange flange quadrangle (as in
Property glass cement).Surface dirt and greasy dirt should be removed before applying sealant.By cross sectional shape, air hose can be divided into circular duct, rectangle wind
Pipe, oblate air hose etc. is a variety of, and wherein circular duct resistance is minimum but height dimension is maximum, and production is complicated.So using with rectangle
Based on air hose.By material, air hose can be divided into metal bellows, composite air duct, macromolecule air hose.
Existing air hose is essentially galvanized iron sheet external thermal insulation air hose, and heat preservation outer layer is one layer of aluminium-foil paper, for a long time by extraneous shadow
The breakage that easily falls off is rung, live crossed construction is easily destroyed, and unsightly, service life is difficult to ensure appearance.
Summary of the invention
According to the above technical problem, the utility model provides a kind of double-deck galvanized sheet rectangular air duct, it is characterised in that including
Internal layer galvanized sheet, outer layer galvanized sheet, liner heat insulation layer, rivet, forked tail filament, zigzag reinforcing strip, U-shaped weather strip, it is described outer
There are four face, the outer layer galvanized sheets to connect into an outer rectangular tube for layer galvanized sheet, and the outer rectangular tube both ends are equipped with flange,
Liner heat insulation layer is installed in the outer layer galvanized sheet, internal layer galvanized sheet is installed on the inside of the liner heat insulation layer,
There are four face, the internal layer galvanized sheets to connect into an interior rectangular tube for the internal layer galvanized sheet, and the internal layer galvanized sheet passes through swallow
Tailfiber, weather strip to connect with outer layer galvanized sheet, the weather strip be it is U-shaped, two end faces of the glass inner-lining cellucotton are equal
It is mounted in weather strip, two sides of the weather strip pass through forked tail filament and internal layer galvanized sheet respectively and outer layer galvanized sheet connects
It connects.
It is connect with the middle part of interior rectangular tube by zigzag reinforcing strip in the middle part of the outer rectangular tube, the zigzag reinforcing strip is horizontal
Wear glass inner-lining cellucotton, one end is connect by forked tail filament or spot welding mode with outer rectangular tube, the other end by forked tail filament with it is interior
Rectangular tube connection.
The utility model has the following beneficial effects: the utility model is that heat-barrier material medial surface is equipped with internal layer galvanized sheet, it is interior
The zinc-plated wooden partition of layer is sliding, reduces windage, increases intensity；
It is outer layer galvanized sheet on the outside of the utility model, outer layer galvanized sheet matter is hard, and it is durable, there is good high-temperature resistant result,
The service life for extending air hose, smoke evacuation and return air air hose suitable for subway；
Reached simultaneously by the way that heat-barrier material is made in the mode inside air hose and complete processing and fabricating in factory, avoids constructing
Scene heat preservation is factory prefabricating power-assisted, guarantees that engineering site is also avoided while quality generates building waste, shortens and applies
The work period.
Detailed description of the invention
Fig. 1 is the utility model schematic top plan view.
Fig. 2 is the utility model schematic cross-sectional view.
Such as figure, outer layer galvanized sheet -1, outer rectangular tube -2, flange -3, screw hole -4, liner heat insulation layer -5, internal layer are zinc-plated
Plate -6, interior rectangular tube -7, forked tail filament -8, weather strip -9, zigzag reinforcing strip -10.
Specific embodiment
Root according to the figure, is further described the utility model:
Embodiment 1

2, outer rectangular tube both ends are equipped with flange 3, and the flange is equipped with screw hole 4, is equipped with liner insulation in outer layer galvanized sheet
Layer 5, liner heat insulation layer inside are equipped with internal layer galvanized sheet 6, and there are four face, internal layer galvanized sheets to connect into one for internal layer galvanized sheet
A interior rectangular tube 7, internal layer galvanized sheet are connect by forked tail filament 8, weather strip 9 with outer layer galvanized sheet, and weather strip is U-shaped, liner
Two end faces of glass fibre cotton are installed in weather strip, and it is zinc-plated with internal layer that two sides of weather strip pass through forked tail filament respectively
Plate is connected with outer layer galvanized sheet.
It is connect with the middle part of interior rectangular tube by zigzag reinforcing strip 10 in the middle part of outer rectangular tube, zigzag reinforcing strip crosses liner
Glass fibre cotton, one end are connect by forked tail filament or spot welding mode with outer rectangular tube, and the other end passes through forked tail filament and interior rectangular tube
Connection.
Embodiment 2
When assembling adjacent upper lower air conduit, by the flange of two section air hoses to good, the screw hole on flange is passed through with bolt and is connected
Get up.
The above is only the preferred embodiment of the utility model, it is noted that for this technology
For the those of ordinary skill in field, without departing from the principle of this utility model, it can also make several
It improves, these improvement also should be regarded as the protection scope of the utility model.
