Abstract
The utility model discloses a double-color steel plate heat insulation wind pipe, which is used for the ventilation and air-conditioning system of construction work. The utility model comprises an outer layer, an inner layer and a heat insulation layer which is clipped by the outer layer and the inner layer, wherein the outer layer, the inner layer and the heat insulation layer form a pipe wall; the outer layer and the inner layer are color steel plates; a longitudinal joint of the color steel plate of the outer layer is a reserved overlapping edge of the color steel plate, and the overlapping edge is assembled by welding with adjacent color steel plates; four longitudinal seams of the color steel plate of the inner layer are sealing gum welding lines. The double-color steel plate heat insulation wind pipe reduces wind leakage, has a good heat insulation effect and long service life, and can save time and stuff when installed; the inner and the outer layers are color steel plates, which enhances the anticorrosion properties of wind pipes and simultaneously enables the appearance of wind pipes to be more beautiful; the utility model is suitable for decorative needs of various environment.
Description
Technical field
The utility model relates to a kind of two color steel thermal insulation wind pipes that are used for architectural engineering ventilation, air-conditioning system.
Background technology
The compound airduct of domestic production at present, the structure more complicated, the longitudinal interface of inside and outside layer adopts the cornerite interconnection technique, promptly at interface with special metal or PVC cornerite, with rivet cornerite and adjacent tube wall are riveted together, be glued between ectonexine and the heat-insulation layer, the construction trouble, the time-consuming material that takes, inleakage is big.And when adopting the PVC cornerite, reduced the fire-protection rating of airduct, and influenced the aesthetic property of appearance.Simultaneously, the inside and outside layer of airduct adopts galvanized steel plain sheet, and antiseptic property is relatively poor, and the service life of airduct is short.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of inleakage little, two color steel thermal insulation wind pipes that antiseptic property is good.
The two color steel thermal insulation wind pipes of the utility model, comprise skin, the internal layer that constitutes tube wall and be clipped in skin and internal layer between heat-insulation layer, outer, internal layer is a color steel, the color steel overlap edge of the longitudinal interface of outer color steel for reserving, this overlap edge and adjacent color steel rivet together, and 4 longitudinal seams of internal layer color steel are the fluid sealant jointing.
The two color steel thermal insulation wind pipes of the utility model, it is characterized in that: according to airduct cross section size, skin can have 1～4 overlap edge respectively.
The two color steel thermal insulation wind pipes of the utility model, wherein the thickness of internal layer, outer color steel is 0.25～1.00mm, middle insulation layer thickness is 20～40mm.
The two color steel thermal insulation wind pipes of the utility model, wherein various forms of flange components can be assembled for flat mouthful in the two ends of airduct.
The two color steel thermal insulation wind pipes of the utility model, wherein airduct inwall or outer wall are provided with girth member.
The two color steel thermal insulation wind pipes of the utility model, the color steel overlap edge of the longitudinal interface of outer color steel for reserving, this overlap edge and adjacent color steel rivet together, 4 longitudinal seams of internal layer color steel are the fluid sealant jointing, saved the cornerite of every joint airduct more than 2, and improved the tightness of airduct, inleakage is reduced.In addition, the skin of this airduct has been avoided use PVC cornerite, thereby has improved the fire-protection rating of airduct.Outer surface outer and internal layer is a color steel, not only makes airduct have better antiseptic power, and can reach more than 20 years service life, and good looking appearance, adapts to all-environment decoration needs.Simultaneously, the airduct two ends are flat mouthful, can assemble the flange component of arbitrary form, and it is more flexible that two color steel thermal insulation wind pipes are installed, and the scope of application is wider.
Below, will cooperate appended graphic explanation in detail by specific embodiment, so that be more prone to the effect understanding the purpose of this utility model, technical scheme and reached.
Description of drawings
The structural perspective of the two color steel thermal insulation wind pipes of Fig. 1 the utility model.
The specific embodiment
Referring to Fig. 1, shown in Figure 1 pair of color steel thermal insulation wind pipe, its cross section is a rectangle, comprises the heat-insulation layer 2 between skin 1, internal layer 3 and skin 1 and the internal layer 3 that constitutes tube wall.Internal layer 3, outer 1 is color steel, and the longitudinal interface of outer 1 color steel can pass through rivet 6 riveteds with the color steel overlap edge 5 and adjacent color steel lapping reserved, or adopts the seaming interlock.4 seams of internal layer 3 color steels are fluid sealant jointing 4.
The thickness of wherein inside and outside layer color steel is 0.25～1.00mm, and middle insulation layer thickness is 20～40mm.
Two color steel thermal-insulating type airducts two ends are flat mouthful, can assemble the flange component of arbitrary form, realize the connection between the pipeline section.
The two color steel thermal-insulating type airduct skins of small bore can be made of a whole plate, have only a longitudinal lap joint limit after the moulding.The two color steel thermal-insulating type airducts in heavy in section can be with 2,3 or the amalgamation of 4 blocks of color steel plates according to size, and this moment, pair color steel thermal-insulating type airduct skins had 2,3 or 4 longitudinal lap joint limits respectively.Under heavy in section, high pressure situation, can girth member be set, increase the bearing capacity of airduct at airduct inwall or outer wall.
The two color steel thermal-insulating type airducts of the utility model are compared with existing compound airduct, and inleakage reduces, long service life, and install the material-saving that saves time.Two color steel thermal-insulating type airduct surfaces externally and internallies are color steel, not only make airduct have better antiseptic power, and can reach more than 20 years service life, and good looking appearance, adapts to all-environment decoration needs.
