Abstract
The utility model relates to a composite wind-pipe cold-bridge free outlaid interpolation flange. The flange is formed by splicing two symmetrical connected aluminum plastic flanges by a flange insert slice. Slots projecting the outer walls of the flanges are arranged on the outer walls of the aluminum plastic flanges, the slots of the two aluminum plastic flanges are correspondingly cooperated to form an inversed C-shaped slot, the flange insert slice is an inverse C-shaped interpolation bar, the inverse C-shaped interpolation bar is correspondingly cooperated with the two aluminum plastic flanges to form the inverse C-shaped slot splice. An aluminum alloy housing is in tenon joint with a PVC flange inner piece to form the aluminum plastic flange, the inverse C-shaped interpolation bar is spliced into the slot on the outer wall of the flange to bunt the two aluminum plastic flanges on the composite wind pipe, therefore the cold bridge free flange connection of the composite wind pipe is realized, thus the composite wind-pipe cold-bridge free outlaid interpolation flange has the features of simple and compact whole structure, convenient assembly, firm connection, good sealing effect and safe use.
Description
Technical field
The utility model relates to a kind of flange arrangement, is that a kind of composite air duct does not have the external interpolation orchid of cold bridge specifically.
Background technique
Though the used flange of air-conditioning composite air duct has been broken away from forms such as traditional angle steel, welding at present, but not enough place is arranged all, though aluminium alloy flange possesses fire protection requirement and soundness; But because aluminum alloy material possesses very high thermal conductivity, be easy to generate the condensation and dewfall at flange place in the application, cause the heat insulation of airduct joint at a distance from cold effect extreme difference; Can not reach the relevant energy-saving and cost-reducing standard of country, and use aluminum alloy material to make flange, expensive; Increase engineering cost; The PVC flange can possess no cold bridge, and cost is low, but can not reach national fire regulation requirement.For adapting to the utilization of two kinds of different materials advantages; The slotting flange of outsourcing that a kind of plastic-aluminum combines has appearred; Like the patent No. is 200820102344.3 disclosed aluminium plastic co-extruding composite air duct adpting flanges, and 2 aluminium plastic co-extruding flange plates that joined by symmetry and flange are transplanted a cutting and formed, and flange is transplanted a cutting in the groove of 2 aluminium plastic co-extruding flange plates that insertion connects; Its deficiency is: I shape flange cutting grafting two plastic-aluminum flanges, and two plastic-aluminum flanges are prone to misplace on flange is transplanted a cutting I shape two opening directions; Other two plastic-aluminum flanged ends faces do not have sealing.Above-mentioned patent can not reach fastening and tight requirement, and flange place condensed water happens occasionally with leaking out, and the airduct of installation can not reach " code for acceptance of construction quality of conditioning works " GB50243-2002 of country standard, and this kind flange can not be used widely.
Summary of the invention
The grafting flange connection that plastic-aluminum combines in the existing technology is not fastening, sealing effect is poor in order to solve, use uneasy congruence not enough; It is a kind of simple in structure, compact that the utility model provides; Be connected firmly, good sealing effect, safe in utilization, composite air duct is installed easily, and not have the external interpolation of cold bridge blue.
The technological scheme that the utility model adopts is: it is blue that a kind of composite air duct does not have the external interpolation of cold bridge; The plastic-aluminum flange that flange is linked to each other by two symmetries is pegged graft through the flange inserted sheet and is formed; Its technical characterstic is the slot that the outer wall of said plastic-aluminum flange is provided with outstanding flange outer wall; The slot corresponding matching of two plastic-aluminum flanges is anti-C type slot, and said flange inserted sheet is to transplant a cutting in the anti-C type, and the anti-C type slot that becomes with two plastic-aluminum flange corresponding matching of transplanting a cutting in the anti-C type is pegged graft.Slot protrudes in the flange outer wall, and external force pressurization origin of force is convenient to assembling and is clamped when can be used as splicing; Cutting and slot are pegged graft outside flange conveniently in the anti-C type, can prevent that flange from misplacing on the butt joint plane, helps the stable connection of composite air duct.
Said two plastic-aluminum flanges are formed by aluminum alloy casing and PVC flange internals, and slot is arranged on the aluminum alloy casing outer wall, and the aluminum alloy casing inwall is provided with grafting tenon mouth, and PVC flange internals one end is provided with the grafting tenon with the corresponding grafting of tenon mouth of pegging graft.The tenon mouth is connected more deeply with tenon, bigger, connect more firmly, guarantee the whole soundness of flange.
Be respectively equipped with the corresponding groove that engages on the butt joint end face of said two plastic-aluminum flanges, groove floor is provided with slideproof tooth, paste heat-preserving sealing joint strip on the slideproof tooth.The butt joint of two plastic-aluminum flanges compresses the thermal-insulating sealing adhesive tape on the slideproof tooth, rises to connect seal action.
Said slot is an inner bevel type grab.Inner bevel type grab with anti-C type in when transplant a cutting pegging graft, have stretchability and soundness preferably, save simultaneously and use material.
Be equipped with anti-skidding teeth on the inwall of said aluminum alloy casing and PVC flange internals; Said aluminum alloy casing and PVC flange internals are by the rivet composite air duct.When composite air duct was plugged between aluminum alloy casing and PVC flange internals, anti-skidding teeth played anti-skidding promptly effect, and it is more firm that the while riveted fixing makes flange be connected with composite air duct.
Said PVC flange internals are provided with a reinforced hole, are provided with at least one reinforcement plate in the reinforced hole, and reinforcement plate is through rivet or bore the silk reinforcing certainly in reinforced hole.Reinforced hole is simplified flange arrangement, and reinforcement plate plays the effect of reinforcing and supporting the airduct both sides in reinforced hole.
Said grafting tenon mouth outer wall is provided with and adds impression.The available lower pressure wheel of going up was adding the extruding of impression place firmly after PVC flange internals were inserted aluminum alloy casing.
The utility model adopts aluminum alloy casing to become the plastic-aluminum flange with PVC flange internals joggle; Transplant a cutting in the anti-C type of in the slot of flange outer wall, pegging graft and make the two plastic-aluminum flanges butt joint on the composite air duct; Thereby the no cold bridge flange of realizing composite air duct connects, and its overall structure is simple, compact, and it is convenient to assemble; Be connected firmly good sealing effect, safe in utilization.
