Abstract
A connecting device of ventilation pipelines comprises two ventilation pipelines which are interconnected, a heteromorphic channel steel flange and a heteromorphic buckle which are respectively installed on the two ventilation pipelines; the inner side of the heteromorphic channel steel flange is a long edge and the outer side thereof is a short edge; the long edge of the inner side is fixedly connected with a pipeline outer wall of a ventilation pipeline end through a pulling rivet; and the ends of the two ventilation pipelines are provided with section bars with U-shaped cross sections, andtips buckled with the ventilation pipelines, and are fixedly connected with the ventilation pipelines through the rivets; the heteromorphic buckle is provided with a catching groove which is matched with the heteromorphic channel steel and is oppositely installed in the heteromorphic channel steel; and the opposite heteromorphic buckle is connected through a bolt; and a sealing gasket is arrangedbetween the opposite section bars with U-shaped cross sections. The connecting device has the advantages of solid connection, reliable quality, material conservation, cost reduction, simple operation,beautiful appearance, good fireproof performance and good sealing performance.
Description
Technical field
The novel connection set that relates to a kind of composite air duct of this use, particularly a kind of composite air duct connection set that adopts inequilateral polymorphic structure and special-shaped card thereof to link to connect.
Background technique
Along with central air-conditioner is universal day by day, the demand of ventilation duct is also increasing, is formed by connecting because the length of ventilation duct saves airduct according to ventilation distance by a joint, so need adopt flange fixedly connected at its joining place.At present, the flange that is used for connecting airduct also has a lot, and as PVC flange, aluminium alloy flange, angle steel flange and plate flange or the like altogether, wherein angle steel flange is commonplace, this flange is that the angle steel by different size is made, need on the monolithic flange, punch after the making, will count the joint airduct with bolt then and link together the good stability of angle steel flange, can satisfy in the GB the little requirement of rectangular air duct physical dimension distortion, but its manufacturing procedure complexity, it is big to expend man-hour, and cost is also higher.Especially deviation appears in the center hole of flange bolt distance easily, thereby has brought many beyond thought difficulties for the field joint airduct, causes at the bottom of the effect and the labour cost increase.The used adpting flange material of composite sheet material airduct generally has angle steel, aluminum alloy and PVC flange profile in the secondly present ventilation and air conditioning engineering, the flange of making of angle steel and aluminum alloy is the cost height not only, and manufacturing procedure complexity, be easy to generate the pitch-row deviation, bring difficulty to installation, general interchangeability is very poor; And adopt the flange of PVC material can adopt I-shaped quickset type, card article formula and hook lock formula Placement, yet adopt I-shaped quickset type and card article formula structure because the restriction of wind-engaging length of tube and mounting point, difficulty is installed, be difficult for being inserted into the position, because there is the composition that environment is had pollution in PVC material itself, health of human body is impacted simultaneously, and the aging easily grade of burning simultaneously of PVC material flange is only for fire-retardant, do not reach the grade of not firing that the high rule of fire-fighting require, therefore can't popularize; If do the flange material with common galvanized sheet, though with low cost, light is done flange with it and is existed insufficient strength, easy deformation, thus interchangeability is affected; Therefore, how to provide that a kind of both costs are cheap, environmental protection, interchangeability is good and the life-span long, intensity greatly and also the wind tube connecting device that does not fire become the ventilation industry and be badly in need of the difficult problem that will solve.
The model utility content
The purpose of this utility model is to provide a kind of ventilation duct connection set, adopts inequilateral abnormity channel-section steel flange and special-shaped buckle thereof, can solve foregoing problems effectively.
Content of the present utility model is: a kind of ventilation duct connection set, comprise interconnective two ventilation ducts, be installed in two by special-shaped channel-section steel flange and special-shaped buckle on the pipeline respectively, the inboard of described special-shaped channel-section steel flange is long limit, the outside is a minor face, fixedly connected with the pipeline outer wall of ventilation duct termination by pulling rivet in inboard long limit, the termination of described two ventilation ducts is provided with the section bar that the transverse section is a U-shaped, spiral-lock is in the termination of ventilation duct, and fixedlys connected with air duct wall by pulling rivet; Described special-shaped buckle is provided with the catching groove with described special-shaped channel-section steel coupling, and is installed in relatively in the special-shaped channel-section steel, connects by bolt between the relative special-shaped buckle; Be provided with sealing gasket between the section bar that described relative transverse section is a U-shaped.
The beneficial effects of the utility model
1, be connected firmly, reliable in quality: owing to airduct is riveted on the long limit, inboard of channel-section steel flange, two channel-section steel flanges by bolt buckle and bolt from around tight lock is connected, so be connected firmly, reliable in quality.
2, economical with materials, reduce cost: overcome and adopted angle steel to manufacture flange in the past, and produced the defectives that unnecessary angle steel are expected, thereby saved the raw material of making flange, reduced fabricating cost at four jiaos of places.
3, simple to operate, specious: punch owing to not be used on the flange during site operation, only two different in nature channel-section steel flanges are linked together by bolt buckle and bolt, therefore simple to operate, save man-hour.Owing to overcome former angle steel flange, improved the appearance quality that airduct connects again because of the restriction that is subjected to geometrical shape, the defective on the high air outlet tube of angle steel facade plane.
4, this connection set has replaced traditional angle steel method flange, aluminum alloy and PVC flange, has not only improved the intensity of flange, and has improved the Security of pipeline, and the burning grade is that the A level is not fired.
5, two special-shaped channel-section steel contacting points sealing gasket is set, has improved the sealability of whole connection set.
6, the transverse section is the end face of the section bar spiral-lock of U-shaped at ventilation duct, play the effect of shielding thermal insulating material on the one hand, prevent that thermal insulating material from exposing, this section bar and ventilation duct are riveted together by pulling rivet not on the one hand, improved by pipeline intensity, make the ventilation duct become as a whole with this section bar.
