Abstract
The utility model relates to a clamping heterotypic U-steel wind-pipe flange profile composed of a U-steel flange, a bolt fastener and a hooked bolt, wherein the U-steel flange is a rectangular frame structure, welded by four heterotypic U-steels having long inner edges, short outer edges and middle grooves. The outer side of the bolt fastener is provided with an eccentric hole. Two sides of the eccentric hole is vertically bent with hooked fasteners. One side of the hooked bolt is provided with a thread and the other side is provided with a bent hook. Two U-steel flanges are oppositely connected together after two U-steel flanges are respectively riveted with the wind pipe. The hooked fastener of the bolt fastener is clamped on the short inner edge of the U-steel flange. The bent hook of the hooked bolt is hooked with inside the groove of the U-steel flange. The threaded side of the hooked bolt is screwed in the eccentric hole of the bolt fastener and secured with the nut. The utility model is used in the ventilating pipeline connecting the equipment, such as the air conditioner; has the advantages of a reasonable structure, a reliable quality, an easy operation, an aesthetic outlook and a low cost.
Description
Technical field
The utility model relates to a kind of ventilation duct link, refers in particular to a kind of seizing type Deformed Channel Steel air duct flange section bar.
Background technique
Universal day by day along with central air-conditioner, the demand of ventilation duct is also increasing, because the length of ventilation duct is formed by connecting by a joint joint airduct according to ventilation distance, so need adopt flange fixedly connected at its joining place.At present, the flange that is used to connect airduct is that the angle steel by different size is made, and need punch on the monolithic flange after the making, will count the joint airduct with nut then and link together, the good stability of angle steel flange can satisfy in the standard 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 connected nut distance easily, thereby has brought many beyond thought difficulties for the field joint airduct, causes the low and labour cost increase of effect.Facade angle steel because of angle steel flange is higher than the airduct plane again, caused and be difficult to the appearance quality common fault that overcomes all the time, brought serious hidden danger of quality for simultaneously the outsourcing thermal insulation layer, for example generate condensed water at jointing easily summer, cause blast connection to leak, thereby influence the construction quality of whole Air-conditioning Engineering.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, reliable in quality, construction is easy, specious and cost is low seizing type Deformed Channel Steel air duct flange section bar.
Technical solution adopted in the utility model is: a kind of seizing type Deformed Channel Steel air duct flange section bar is made of channel-section steel flange, nut buckle and hook-shaped nut.Wherein, the channel-section steel flange is a rectangular frame structure, and is that long limit, the outside are that minor face, centre are that the Deformed Channel Steel of groove is welded by four inboards; The outer side of nut buckle is provided with eccentric opening, and the two ends vertical curve of eccentric opening has hook-shaped button; One end of hook-shaped nut is a screw thread, and the other end is that bending colludes.Two channel-section steel flanges oppositely are docking together respectively with after the airduct riveted joint, the hook-shaped button of nut buckle is connected on the minor face of a channel-section steel flange, the bending hook joint of hook-shaped nut is in the groove of another channel-section steel flange, and the threaded end of hook-shaped nut is socketed in the eccentric opening of nut buckle and by nut and is fastened.
The beneficial effects of the utility model are:
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 nut buckle and hook-shaped nut 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 of unnecessary angle steel clouts, thereby saved the raw material of manufacturing flange, reduced and manufactured 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 channel-section steel flanges are linked together by nut buckle and hook-shaped nut, 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.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done to describe in further detail.
To shown in Figure 7, a kind of seizing type Deformed Channel Steel air duct flange section bar is made of channel-section steel flange 1, nut buckle 2 and hook-shaped nut 3 as Fig. 1.
As shown in Figure 1 and Figure 2, channel-section steel flange 1 is a rectangular frame structure, and is that long limit, the outside are that minor face, centre are that the Deformed Channel Steel of groove is welded by four inboards, and two channel-section steel flanges use in pairs.
As Fig. 3, Fig. 4, shown in Figure 5, the outer side of nut buckle 2 is provided with eccentric opening, and the two ends vertical curve of eccentric opening has hook-shaped button, and this bolt buckle is used for channel-section steel flange of clamping.
As Fig. 6, shown in Figure 7, an end of hook-shaped nut 3 is a screw thread, and the other end is that bending colludes, and this bending colludes and is used for another channel-section steel flange of hook joint.
As shown in Figure 8, earlier the airduct 5 of air-conditioning is socketed on the inside of channel-section steel flange 1 during use and rivets mutually, have the channel-section steel flange 1 of airduct oppositely to be docking together two cover riveted joints again with long limit, the inboard of channel-section steel flange.Hook-shaped button by nut buckle 2 is connected on the outside minor face of a channel-section steel flange, and the bending hook joint of hook-shaped nut 3 is in the groove of another channel-section steel flange, and the threaded end of hook-shaped nut 3 is socketed in the eccentric opening of nut buckle 2 and to tighten the back by nut 4 fixing.The channel-section steel flange can be made the serial section bar with the long limit of different size and minor face according to the material and the thickness of airduct, is applicable to that the various airducts that sheet metal, organic board are manufactured connect.Adopt this channel-section steel flange connect airduct simple to operate, save man-hour, reliable in quality, saving material, have the complete generous advantage of outward appearance simultaneously.
