Abstract
The utility model relates to a quick connection rectangle flange air pipe. The utility model is characterized in that an end head on the pipe wall of each side of the rectangle air pipe is flanged to form a shape of a flange wing edge; the right angle spliced by two contiguous pipe walls is provided with a right-angle joint inserting strip with a wrap angle flange, a strengthening concave rib, and a hole for hoisting; the mutually connecting point of the pipe segment of the rectangular air pipe is provided with a flange spring clip of a thin steel plate for clipping the flange wing edge. Compared with the flange connecting air pipe of the angle steel, the utility model has the advantages that the weight of the flange can be reduced, quick installation on site can be realized, and the work efficiency can be improved by four times. When the side length of the rectangular air pipe is less than 1.5 meters, a carriage for hoisting is not needed. The utility model is suitable for the rectangular air pipe with high, middle and low pressure and the connection of a tee joint, a muffler and an air valve which are matched with the rectangular air pipe.
Description
The utility model belongs to airduct, particularly a kind of rectangular flange airduct that adopts sheet metal flange springs folder to connect fast.
At present, in the ventilation and air conditioning engineering, the Placement of airduct mainly adopts angle steel flange to be connected with bolt, on making, need process airduct and two parts of flange respectively, the making of angle steel flange, need cutting, punching and welding, with rivet angle steel flange is riveted to two ends of airduct then, couple together with the angle steel flange of bolt again during installation two airducts.General a pair of flange connects needs to twist tens bolts.This mode needs many with variety of raw material, and metal wastage is big, and installation rate is slower.For improving installation efficiency, alleviate airduct weight, there is the employing can't blue Placement, as bayonet joint, airduct is processed into taper, during installation the microcephaly is inserted in the major part, strengthen connecting with self tapping screw or self-plugging rivet, but dismounting inconvenience; Quickset type connects, and when airduct is made, with the airduct two ends, routs up the stile of 90 degree, couple together with C shape, S shape or the vertical bar shaped cutting stile with two airducts during installation, but the sealing of joint is poor, can only be used for the low pressure airduct.Though more than two kinds can't blue Placement can alleviate airduct weight, improve installation efficiency, because of joint intensity is lower, poor sealing performance, inleakage is big, the actual use seldom.
The purpose of this utility model is, design and produce a kind of quick connection rectangular flange airduct, adopt the right angle to connect and transplant a cutting and sheet metal flange springs folder, make it can alleviate airduct weight, can connect fast again, good seal performance is with the rectangular air duct of the quick connection that is applicable to the high, medium and low voltage pipe-line system.
Quick connection rectangular flange airduct of the present utility model, form by airduct, flange, link, it is characterized in that, every facial canal wall termination flange of rectangular air duct becomes flange edge of a wing shape, the place, right angle of adjacent tube wall splicing, the right angle that is provided with band cornerite flange, reinforcement concave bar and erection opening is connected cutting, and the rectangular air duct pipeline section interconnects the place, is provided with the sheet metal flange springs folder on the clamping flange edge of a wing.
Making and use method of the present utility model is, the rectangular flange airduct is to make by four tube walls, earlier sheet metal is cut out by the size of each sheet requirement, to cut out each good sheet tube wall two ends with special-purpose machinery and be pressed into limit, flanged flange edge of a wing, four tube walls that will suppress again carry out the seaming splicing, during splicing the right angle connected and is inserted on four angles at tube wall two ends, rectangular flange airduct pipeline section; The right angle connects the making of transplanting a cutting, and earlier steel plate is cut into 140 millimeters lath, with punch press and the continuous punching press of press tool, a drawing; The making of sheet metal flange springs folder is, earlier steel plate is cut into 50 millimeters lath, with the special-purpose machinery extruding, once is pressed into L shaped sheet metal flange springs folder, is cut into the length that needs with cutting machine again.During installation, earlier Stamping Steel Ribbon is pasted on the flange edge of a wing with binder, in order to avoid come off when connecting, put the airduct position that will install again, and the sheet metal flange springs is folded up on the little limit of airduct, after alignment is found at two ends accurately, pull with special-purpose spanner one again, can sheet metal flange springs mounting board is tight, and then use same quadrat method, tight the sheet metal flange springs mounting board on the big limit of airduct, promptly finish the connection of rectangular flange airduct.
The utility model has the advantages that, be connected airduct with angle steel flange and compare that adopt variety of raw material single, all component are all made of sheet metal, have reduced raw-material buying hour; The sheet metal flange is compared with angle steel flange, can alleviate 3/4ths weight; Do not need during on-the-spot the installation to wear screw, twist nut, can improve four times of on-the-spot installation efficiency to the sealing gasket punching; When the rectangular air duct length of side less than 1.5 meters, also do not need to make in addition ceiling mount bracket, directly connect and transplant a cutting the erection opening lifting of reserving with the right angle.Be applicable to rectangular air duct that the sheet metal of the high, medium and low voltage pipe-line system that ventilation and air conditioning engineering is used is made and with being connected of its supporting threeway, four-way, silencing apparatus, air-valve.
Below in conjunction with drawings and Examples, the utility model will be further described:
Fig. 1 is the organigram that connects the rectangular flange airduct fast
Fig. 2 is the tube wall construction schematic representation that connects the rectangular flange airduct fast
Fig. 3 is that the right angle that connects the rectangular flange airduct fast connects the organigram of transplanting a cutting
Fig. 4 is the organigram that connects the sheet metal flange springs folder of rectangular flange airduct fast
As seen from the figure, connect the rectangular flange airduct fast, form by airduct, flange, link, every facial canal wall 1 termination flange of rectangular air duct becomes flange edge of a wing shape, the place, right angle of adjacent tube wall splicing, the right angle that is provided with band cornerite flange 4, reinforcement concave bar 5 and erection opening 6 is connected transplants a cutting 2, connects the vertical edge of transplanting a cutting at the right angle and is provided with zigzag fashion anti-slip tank 7, and rectangular air duct pipeline section link is the sheet metal flange springs folder 3 on the clamping flange edge of a wing.
Claims (2)
1, a kind of quick connection rectangular flange airduct, be made up of airduct, flange, link, it is characterized in that, every facial canal wall termination flange of rectangular air duct becomes flange edge of a wing shape, the place, right angle of adjacent tube wall splicing, the right angle that is provided with band cornerite flange, reinforcement concave bar and erection opening is connected cutting.
