The air pipe is mainly characterized by comprising an inner wall and an outer wall formed by color steel plates; a thermal insulation layer is arranged between the inner wall and the outer wall; the inner wall and the outer wall are seaming formed full plates; the inner wall is the joint-corner seaming formed full plate; and the outer wall is the stud seaming formed full plate. When the energy-saving and environment-friendly double-faced color steel plate composite air pipe is manufactured, the full plates are bent to form the inner wall and the outer wall in a seaming forming manner; the dimension of the outer wall is greater than that of the inner wall; the inner wall is sleeved with the outer wall; a thermal insulation material is added between the inner wall and the outer wall to form the thermal insulation layer; the inner wall adopts the full plate seaming forming, so that defects of ageing, cracking and fiber exposure due to long-time use are overcome; and the air pipe has the advantages that the air pipe is green, environment-friendly, energy-saving, excellent in thermal insulation property, light in weight, high in strength, high in adaptability, and long in service life.
Description
Technical field
The utility model belongs to air conditioner ventilation pipeline technical field, relates in particular to a kind of energy saving and environment friendly two-sided color steel composite air duct.
Background technique
In buildings such as hotel, apartment, hospital, office building, office building, the ventilation duct that central air-conditioner and ventilation system are used, the advantage of two-sided color steel composite air duct set galvanized sheet iron airduct and composite air duct, both had galvanized sheet iron airduct good rigidity, advantage that intensity is big, have composite air duct again and do not need the secondary insulation, the performance of sqouynd absorption lowering noise just is widely used.When existing color steel composite air duct is produced, earlier that inwall color steel, outer wall color steel, thermal insulation layer is compound, be similar to sandwich shape flat board, then bending part is rejected the breach at a right angle, thereafter the side's of folding moulding, use four jiaos of sealant sealing inwalls again, aging, the cracking of sealer can appear in long-time use, causes fiber to blow outward.Environment and the person are caused damage.
The model utility content
The technical problems to be solved in the utility model just provides a kind of good leak tightness, is not prone to cold bridge phenomenon, and processing and fabricating is easy, the energy saving and environment friendly two-sided color steel composite air duct that labor intensity is low.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise the inner and outer wall that color steel sheet constitutes, be provided with thermal insulation layer between the inner and outer wall, described inner and outer wall is whole sheet material of seaming moulding.
Its additional technical feature is: described inwall is whole sheet material of associating angle seaming moulding, and outer wall is whole sheet material of hidden discount seaming moulding; The cross section of described inner and outer wall is rectangle, square, circle; The unit weight of described thermal insulation layer is equal to or greater than 80 kilograms/cubic metre, and thickness is 20---and 30 millimeters.
The energy saving and environment friendly two-sided color steel composite air duct that the utility model provides compared with prior art, inner and outer wall is whole sheet material of seaming moulding.During manufacturing, inner and outer wall is made in the moulding of whole sheet material bending seaming, outer wall is bigger than inwall size, the little tube of both big jacket casings, and between adds thermal insulating material and constitutes thermal insulation layer.Because inwall adopts the moulding of whole sheet material seaming, do not re-use four jiaos of technologies with the glue sealing after the inwall cutting moulding, avoided long-time use season cracking to occur, the drawback that fiber is gone out.Have green, environmental protection, energy-saving advantages, a series of advantages such as heat insulating ability, high-strength light, the adaptability with brilliance is strong, long service life.As required, inwall is whole sheet material of associating angle seaming moulding, and outer wall is whole sheet material of hidden discount seaming moulding.And the cross section of inner and outer wall is rectangle, square, circle, can certainly be other shapes.The unit weight of thermal insulation layer is equal to or greater than 80 kilograms/cubic metre, and thickness is 20---and 30 millimeters.
In the working process, the ventilation duct inside and outside wall all adopts zinc-plated color coated steel sheet, use numerical control airduct to produce three lines, reaches roll bending and opens flat, folding side, shear.The control of each spot size error is at 0.1/1000mm, avoided that old technology cutting size is inaccurate, flange is installed situation of difficult.And the airduct inwall adopts associating angle seaming form moulding, reaches the advantage that air leak rate of air curtain is low, bulk strength is high.Airduct outer wall protective layer adopts hidden discount seaming form, makes appearance looks elegant, clean and tidy, bulk strength is high.Nontoxic glue and fill unit weight 80kg/m between the airduct internal and external layer
3More than, thickness is the glass plate of 25mm.Adopt PVC grooved closure fange or aluminum alloy bridge insulation thermal resistance flange after the pipeline moulding, the cassette quick-mounting connects, and prevents cold bridge phenomenon.
The advantage of the energy saving and environment friendly two-sided color steel composite air duct that the utility model provides is:
1, size is accurate: produce three lines by the automatic airduct of numerical control and realized that roll bending opens flat, bending, cuts off, guaranteed the flatness of sheet material and the integrity of outward appearance, controlled size precision is built in 0.1/1000mm, the outward appearance no marking;
2, do not have leak out, no cold bridge: compare traditional color steel composite air duct, this product inside and outside wall adopts whole plate once-through seaming form, and air leakage phenomena can not take place, and also has the bridge insulation thermal resistance flange of special use can effectively prevent the generation of cold bridge phenomenon;
3, the validity of numerically controlled processing equipment has guaranteed that thereby the interchangeability in same size air channel improves installation efficient;
4, improved the material utilization rate, reduced the waste of glass plate, the environmental pollution of saved steel, having avoided the glass defective work to cause simultaneously.Former technology must be cut out earlier at bending part and be cut, and comparing every joint airduct, will to throw away a part of color steel be waste product;
5, the reduction of erection time: because the numerical control processing technology design technology, the duration is compared with traditional airduct processing technology, can improve 10 times of effects; Reduce labor strength, improved manufacturing efficiency;
6, anti-seeing attractive in appearance: digital control processing preparation process and ripe arrangement and method for construction, reduce the complicated process in the manual work, reduced the surface friction in the course of working, make the product surface no marking.
