As a compound ventilation duct connecting device, the connection and fixation method thereof can be chosen flexibly in accordance with the technical requirements and sit actual working conditions, such as bolted connection, riveted connection, or spring clamping plate connection are all available to selection; the utility model has the advantages of simple, convenient and flexible operation, low labor intensity, fast connection and mounting, and working hour saving, in addition, compared with the U shape plane flange connection, the efficiency thereof can be increased 3 to 5 times, and the excess material left by material marking can still be used continuously, which produces no influence on the connecting effect and saves the material as well; the ventilation duct has the advantages of firm and reliable connection and excellent sealing ability. The two flanges of the utility model can meet the requirements of all current ventilation ducts.
Description
One, technical field
The utility model relates to the flange connecting apparatus that ventilation duct is used, and is that a kind of F type does not have the composite air duct plastic-steel adpting flange of cutting and a kind of U type does not have the composite air duct of cutting plastic-steel adpting flange specifically.
Two, background technique
The present domestic ventilation duct that generally adopts composite air duct (for example: polyurethane, phenolic aldehyde, glass, polystyrene) as central air-conditioner.Ventilation duct field fabrication operation is; At first with the sheet material of 1200mm * 4000mm * 21mm specification by artificial cutting, cut into the airduct size of design drawing requirement, with sheet material glue the plate adhesion that cuts being become the both ends open cross section then is the square tube of rectangle, promptly makes a joint airduct pipeline.Connection between the two joint airduct pipelines is two horseshoe clamp face flanges, sticks with glue respectively to be connected on two airduct pipelines to be connected, then by I-shaped cutting is inserted (as shown in Figure 1) of realizing in the connection slot of two horseshoe clamp face flanges.Use horseshoe clamp face flange to connect airduct and have following defective: reach the interconnection technique requirement, i.e. sealing requirements and soundness requirement, then two manufactured size trueness errors that connect airduct must be in 2mm.In the practice of construction operation, it is by manually being made respectively that each section connects airduct, manufactured size trueness error between these just feasible most two airducts to be connected, considerably beyond the 2mm of horseshoe clamp face flange connection request, its actual fabrication trueness error can reach 20mm.Under this trueness error situation, use horseshoe clamp face flange to connect airduct, I-shaped cutting can't be wedged in the connection slot of two horseshoe clamp face flanges, even wedge by force, also can burst the connection slot of horseshoe clamp face flange.This does not only reach sealing requirements, does not more reach the soundness requirement, can't guarantee the quality requirement that airduct connects, and take a lot of work, time-consuming, expense material.
Three, model utility content
For overcoming above-mentioned the deficiencies in the prior art, the purpose of this utility model provides a kind of good airproof performance, nothing easy to install, the saving of work and time material saving and transplants a cutting composite air duct plastic-steel adpting flange.Technical solution of the present utility model is to transplant a cutting composite air duct plastic-steel adpting flange and realize by adopting cross section to be nothing that F shape and cross section take the shape of the letter U:
Scheme one: a kind of F type does not have the composite air duct of cutting plastic-steel adpting flange, and flange is once extruded drawing and forming, it is characterized in that; The top clamping plate of socket clamping plate and bottom plate and connecting plate face are perpendicular, the connecting plate lower end is mutually concordant with the bottom plate of socket clamping plate, the outer 15mm-35mm of top clamping plate is stretched out in the connecting plate upper end, connecting plate top has a steel gusset to embed wherein, one rectangular through-hole is arranged at the connecting plate bottom, and the cross section of flange integral body is " F " shape;
Scheme two: a kind of U type does not have the composite air duct of cutting plastic-steel adpting flange, and flange is once extruded drawing and forming, it is characterized in that; The socket clamping plate parallel with the connecting plate face, have only clamping plate, and connecting plate is than the long 15mm-35mm of clamping plate, and connecting plate top has a steel gusset to embed wherein, and a rectangular through-hole is arranged at the connecting plate bottom, and the cross section of flange integral body is " U " shape.
The F type does not have transplants a cutting composite air duct plastic-steel adpting flange and U type and does not have and transplant a cutting the steel gusset of composite air duct plastic-steel adpting flange can to select thickness for use be the 0.5mm-2.5mm steel plate.
The beneficial effects of the utility model are, in the practice of construction operation, the error precision that airduct is made does not influence the airduct quality of connection, so, trueness error to every joint airduct of making does not respectively have harsh requirement, to make trueness error at 20mm with interior airduct, all can satisfy the technical requirements that the airduct pipeline connects; Adopt the utility model can select to be connected and fixed mode neatly, according to technical requirements and on-the-spot actual job condition can select corresponding link (such as: bolt is connected or rivet connects or the spring clip plate connection) connect; Operation is simple, convenient, flexibly, labor intensity is low, connection speed is fast, saves man-hour, can raise the efficiency 3-5 doubly with adopting horseshoe clamp face flange to be connected to compare, and the clout that produces during blanking can connect use, does not influence the connection effect, the saving material; The airduct pipeline that adopts the utility model to connect, firm and reliable connection, and good airproof performance.The F type that only needs the utility model to provide does not have the composite air duct plastic-steel adpting flange of cutting and the U type does not have the composite air duct of cutting plastic-steel adpting flange, just can satisfy the connection needs of all airducts now.
