Abstract

The utility model relates to a ventilating pipe made of a composite material and belongs to the construction ventilating field. The utility model is provided with a straight pipe structure, a diameter changing structure, a three-way structure, a quadrangular structure, etc., and has the advantages of lighter weight, low cost, high intensity, no wind leakage, convenient construction, beautiful appearance, long service life, etc.

Description

The NEW TYPE OF COMPOSITE airduct

Technical field

The utility model belongs to the building ventilation field, specifically the composite air duct made from composite material that is used for changes in temperature ventilation and anti-smoke evacuation.

Background technique

Existing ventilation duct generally adopts metal tube such as tin plate, aluminum alloy etc., and this airduct cost is higher, and get rusty easily, the air leak rate of air curtain height, its weight is big besides, soundness is poor, with building member wear long fasten connection after, because of load is bigger, influence the safety in utilization of member.

Summary of the invention

That the utility model will solve is cold, warm air-supply with ventilation duct or cost greatly, easily get rusty,, the high soundness of air leak rate of air curtain is poor, the shortcoming that safety in utilization is not high enough provides a kind of NEW TYPE OF COMPOSITE airduct for this is practical.

For addressing the above problem, the technical solution adopted in the utility model is with platform cutting machine or portable cutting machine, composite board is cut into the plate of suitable size, again with the two ends up and down of left side plate, cut into the ladder surface of 90 degree, the back prescinds the thermal insulation layer on the ladder surface of side plate with knife for tools, guarantees the smooth of ladder surface part, apply special adhesive at side plate ladder surface place subsequently, fasten airduct is female with fixing device at last.

This is practical to have: weight is lighter, cost is lower, intensity is high, easy construction, do not leak out, advantage such as attractive in appearance and long service life.

Mode of execution

Below in conjunction with description of drawings, to this practical being further elaborated.

Fig. 1-Fig. 4 is a preferred version of the present utility model, with platform cutting machine or portable cutting machine, composite board is cut into the plate of suitable size, again with the two ends up and down of left sideboard 1 and right sideboard 2, cut into the ladder surface 3 of 90 degree, the back prescinds the thermal insulation layer on the ladder surface 3 of side plate with knife for tools, guarantees the smooth of ladder surface 3, apply special adhesive at side plate ladder surface 3 places subsequently, with fixing device 4 airduct is tied up the jail at last.Heavy in section airduct four jiaos of junction of wall within it increases and pastes stiffener 5, if the overlength airduct will be provided with flexible knot 6 and anti-swinging rack 7 in the junction of two airducts.

The making of reducing airduct is identical with the way of diameter airduct, is the sheet material Bevel with blast pipe board one or both sides wherein.

The making of three ventilation ducts of same cross-sectional is identical with the way of diameter airduct, just the guide plate 8 of air supply direction will with 9 one-tenths 45 angles of spending of air main, the side plate excision forming is also made ladder surface, the back applies special adhesive at ladder surface, fixing with fixing device 4, clear up surplus glue, plug the gap, be placed on smooth place and solidify.
