Abstract
A kind of composite air duct of the present utility model relates to airduct field, be made up of outer tube wall, thermal insulation layer and inner tubal wall, its inner tubal wall is placed in outer tube wall, and uniform support link between the periphery of inner tubal wall and the inner circumferential of outer tube wall, fill gaps between inner tubal wall and outer tube wall have thermal insulation layer.A kind of composite air duct of the present utility model, structure is simple, and easy to make, stability is high, and overcome the problem that conventional construction cannot be cleared up after inside increases strut, good seal performance, durable, fireproof performance is good, and service cycle is long.
Description
Technical field
The utility model relates to airduct field, particularly relates to a kind of composite air duct.
Background technique
Airduct by a large amount of uses in the field such as clean room, market, the light assembled room of body, wall thermal insulating, fire prevention sandwich door, wind pipe of central air-conditioning, cold and hot conveyance conduit etc. is equipped with in such as these Architecture Designs, the material of airduct tube wall is mainly made up of upper and lower two-layer color steel and the thermal insulation layer be positioned in the middle of color steel, and airduct outer wall and inwall four faces are all split type, be that then the V-type groove cutting out 45 degree in this composite sheet is converted into square when airduct makes.Coat sealer or welded seal at knuckle place, therefore overall just outer wall is one, inwall is split, when airduct is oversize, can produces built on the sand and rock, tilt, steadiness extreme difference, tradition is that this mode not only has impact to sealing by increasing strut at interior hollow space, and processing is installed complicated, particularly to the cleaning of inside, usual small machine people clears up, and middle strut can block, and cannot realize cleaning.
Model utility content
This practicality is for Problems existing in background technique, and a kind of composite air duct provided.
A kind of composite air duct of the present utility model, be made up of outer tube wall, thermal insulation layer and inner tubal wall, its inner tubal wall is placed in outer tube wall, and uniform support link between the periphery of inner tubal wall and the inner circumferential of outer tube wall, fill gaps between inner tubal wall and outer tube wall have thermal insulation layer.
As preferably of the present utility model, the periphery, two ends of described outer tube wall is provided with chimb, uniform screw on chimb.
As preferably of the present utility model, described outer tube wall and the two end part of inner tubal wall are equipped with Stamping Steel Ribbon.
A kind of composite air duct of the present utility model, structure is simple, and easy to make, stability is high, and overcome the problem that conventional construction cannot be cleared up after inside increases strut, good seal performance, durable, fireproof performance is good, and service cycle is long.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic cross-section of the present utility model.
Embodiment
Below in conjunction with accompanying drawing 1 to a kind of composite air duct of the present utility model, elaborate.
A kind of composite air duct of the present utility model, be made up of outer tube wall 1, thermal insulation layer 2 and inner tubal wall 3, its inner tubal wall 3 is placed in outer tube wall 1, and uniform support link 4 between the periphery of inner tubal wall 3 and the inner circumferential of outer tube wall 1, fill gaps between inner tubal wall 3 and outer tube wall 1 have thermal insulation layer 2.The periphery, two ends of described outer tube wall 1 is provided with chimb 5, uniform screw 6 on chimb 5.Described outer tube wall 1 and the two end part of inner tubal wall 3 are equipped with Stamping Steel Ribbon 7.
Airduct is made all-in-one-piece, first inwall can be converted into square-tube-shaped in actual manufacture, because thermal insulating material is fragility, be attached to respectively by thermal insulating material outside four inwalls, between the thermal insulating material at four sides, linkage structure can be the modes such as phase contract again, then at the outer clad metal outer wall again of thermal insulation layer, equal glue coated between thermal insulation layer and inner tubal wall and outer tube wall, metallic walls is converted into square-tube-shaped, seam crossing rivet interlacement by one block of sheet material, and this all-in-one-piece airduct intensity and sealing are all improved.
As known by the technical knowledge, the utility model can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Allly all to be included in the utility model within the scope of the utility model or being equal to the change in scope of the present utility model.
Claims (3)
