Description
Technical field
The utility model relates to a kind of ventilation duct flange profile, refers in particular to a kind of locking-type aluminium foil composite sheet air duct flange section bar that colludes.
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.The air duct flange connecting means of being made by aluminium foil glass and aluminium foil composite phenol formaldehyde warming plate at present generally has four kinds, a kind of is to process flange with angle steel, then in its jointing punching, with bolt number joint airduct is linked together again, adopt this method flange connecting, good stability, the error of its interface are little, basically can guarantee the physical dimension of airduct, but its manufacturing procedure complexity, the cost height especially error occurs easily when punching for flange, often bring difficulty to construction, and the metal angle flange is higher than the airduct facade, influences the appearance quality of airduct easily.Also a kind of is the flange-interface of processing with aluminium alloy extrusions, and its advantage is similar substantially with the use angle steel, and shortcoming is the cost height, and except that special requirement, few people use.Another kind is an overlap joint type, utilize self thickness of aluminium foil glass composite board, joint at the airduct two ends respectively cuts 1/2 of sheet metal thickness, the plane equal in length that two ends are cut, with glue two planes that stay are bonded together, reinforced by self threading pin after respectively installing one in inside and outside with the galvanized sheet that equates, the air conditioning wind pipe shortcoming of this overlap joint type is a lot of, generally can not adopt for the engineering that quality requirement is arranged again.Another is to do flange with quickset type flame-proof PVC section bar, because the restriction of cutting is installed, airduct can't be transplanted a cutting with this for four jiaos and be connected, so need do four cornerites in addition it is covered completely, and not only the cost height is not attractive in appearance yet.
Summary of the invention
The purpose of this utility model provide a kind of rational in infrastructure, in conjunction with tight, construction is easy, specious and cost is low colludes locking-type aluminium foil composite sheet air duct flange section bar.
Technical solution adopted in the utility model is: a kind of locking-type aluminium foil composite sheet air duct flange section bar that colludes, and by colluding groove 1, colluding and cover 2 and 90 ° of outer cornerites 3 and constituted.Collude groove 1 and be bar shaped, its outside is a Baltimore groove, and the inboard has extended upward colludes the groove overhead kick.Colluding and covering 2 is bar shaped, and its both sides are extended with colluding of symmetry downwards and cover overhead kick.90 ° of outer cornerites 3 are right angle type, its dual-side extend internally respectively the symmetry outer cornerite overhead kick.Collude the jointing that groove 1 is plugged on two rectangular air ducts, collude and cover adjacent two the colluding on the groove 1 of 2 clampings, and cover overhead kick two rectangular air ducts are linked together by colluding the groove overhead kick and colluding, the dual-side that 90 ° of outer cornerites 3 are plugged on the rectangular air duct corner colludes in the groove.
Collude in the Baltimore groove of groove 1 and be provided with anti-slip tank.
The outer wall that colludes the groove overhead kick is provided with a plurality of Stamping Steel Ribbon mounting grooves, is equiped with Stamping Steel Ribbon 6 in the sealing bar mounting groove.
The beneficial effects of the utility model are:
1, rational in infrastructure, construction easily: owing to collude groove, collude lid and 90 ° of outer cornerites and be molded as section bar by the interpolation of PVC raw material behind the anti-aging and flame retardant material, the duct collar that only needs in the construction to be docked is inserted the Baltimore groove that colludes the groove outside, employing is colluded locking-type and is connected just and two airducts can be covered overhead kick and link together securely by colluding the groove overhead kick and colluding, so has guaranteed interior pipe quality of connection, easy construction and high working efficiency.
2, in conjunction with tight, aging quality resistance is good: because two airducts are to cover overhead kick and link together securely by colluding the groove overhead kick and colluding, and the joint of colluding groove in both sides is equiped with Stamping Steel Ribbon, at the edge hook joint of airduct cornerite outside 90 ° is arranged, so good seal performance, reduced the inleakage of adpting flange, need not weld, need not punch, need not bolt and connect, need not brush rust proof paint, do not use thermal insulation material, the saving of labor, laborsaving, reduced construction cost significantly.
3, making is easy, cost is low: because therefore the molded section bar that forms that adopts can be processed flange at the scene according to the needs of constructing, the construction cost that the cost of production of flange is connected with airduct is all lower.
4, specious, applied range: owing to connect without bolt, the outer surface of section bar does not use thermal insulation material, therefore the outer surface smoother of airduct joint is bright and clean, has graceful moulding, along with popularizing of the bright dress airduct of house ornamentation central air-conditioner, the airduct of every composite sheet thickness between 21-30mm all can use the flange of this section bar processing, can also be applied to the connection of various airduct pipelines after the sale as the building materials commodity.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done to describe in further detail.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of locking-type aluminium foil composite sheet air duct flange section bar that colludes, by colluding groove 1, colluding and cover 2 and 90 ° of outer cornerites 3 and constituted, it manufactures material is that the PVC raw material adds anti-aging and flame retardant material, and manufacture technology is to make strip section and cornerite through mould.Collude groove 1 and be bar shaped, its outside is a Baltimore groove, and the inboard has extended upward colludes the groove overhead kick, and colluding and covering 2 is bar shaped, and its both sides are extended with colluding of symmetry downwards and cover overhead kick.
As Fig. 1, Fig. 5, shown in Figure 6, during use, earlier the interface insertion of two rectangular air ducts 5 is colluded in the Baltimore groove in groove 1 outside, cover 2 and be connected to the colluding on the groove 1 of two symmetries colluding again, and cover overhead kick two rectangular air ducts 5 are linked together by colluding the groove overhead kick and colluding, collude on the Baltimore groove inwall of groove 1 and be respectively equipped with anti-slip tank 4, in order to prevent colluding groove and rectangular air duct breaks away from.The outer wall that colludes the groove overhead kick is provided with 2 Stamping Steel Ribbon mounting grooves, is equiped with Stamping Steel Ribbon 6 in the sealing bar mounting groove, to improve the sealing effect of air duct flange section bar.90 ° of outer cornerites 3 are right angle type, extend internally the respectively outer cornerite overhead kick of symmetry of its dual-side, and the dual-side that 90 ° of outer cornerites 3 are plugged on four corners of rectangular air duct colludes in the groove, in order to keep specious and the enhancing sealability.
Because adopting, the utility model colludes lock construction, therefore in conjunction with tight, simple installation, the material-saving that saves time, specious, long service life.
