Abstract
The utility model relates to an air duct connecting device, and specifically relates to a composite board type air duct bridge-cutoff connecting flange. The utility model solves the problems that the existing composite air duct connecting flange is subjected to a large air leak quantity and can not be sized easily. The composite board type air duct bridge-cutoff connecting flange comprises two flange bodies which have a U-shaped cross section and are symmetrically connected, and a C-shaped flange insertion bar, wherein each flange body is composed of a half aluminum alloy flange piece and a half PVC (polyvinyl chloride) flange piece which are matched with each other, the outer end part of a connecting surface of each aluminum alloy flange piece is provided with a hook, and both ends of the C-shaped flange insertion bar are respectively inserted into the hooks of the two aluminum alloy flange pieces; and the connecting surface of each aluminum alloy flange piece is provided with a joint strip groove, and a joint strip is placed between the two joint strip grooves. The utility model has the advantages of simple structure and delicate design, and can be widely applicable to the connection of composite air ducts.
Description
Technical field
The utility model relates to wind tube connecting device, is specially a kind of composite sheet airduct bridge cut-off adpting flange.
Background technique
Phenolic aldehyde composite sheet airduct is phenolic foam board and aluminium foil or the compound sandwich board of processing of iron sheet; Its cross section is square, and is on-the-spot by the moulding of design specification dimensioned, once lifting, need not add thermal insulation layer again; The airduct internal surface is smooth, smooth and outer surface is bright in luster, is particularly suitable for bright dress.At present four limits of airduct all are to lean on that flange connects and the corner of airduct is fixed together two adjacent flanges through zinc-plated offset angle; Flange comprises that the cross section that two symmetries are joined is the flange body of U type; Flange body is made up of half sheet aluminium alloy flange sheet and half sheet PVC flange plate, and the junction surface outer end of aluminium alloy flange sheet is provided with grab, and insert respectively in the grab of two aluminium alloy flange sheets at the two ends that C type flange is transplanted a cutting; Have following problem after the installation: the jointing of two flange body utilizes aluminum alloy plane, the butt joint of PVC plane and adopts the C type to transplant a cutting and connects; The diagonal error surpasses 3mm, the supergage requirement, and inleakage is bigger; Need be after airduct connects in airduct inside to the jointing cementing sealing of two flange body, big airduct can advance people's operation, and little airduct then can't advance people's operation, have to utilize long handle instrument cementing, but can't guarantee the gluing quality like this.
Summary of the invention
The utility model provides a kind of composite sheet airduct bridge cut-off adpting flange in order to solve the existing problem that composite air duct adpting flange inleakage is big and gluing is difficult.
The utility model is to adopt following technological scheme to realize: a kind of composite sheet airduct bridge cut-off adpting flange comprises that the cross section that two symmetries are joined is the flange body and the cutting of C type flange of U type; Flange body is made up of half sheet aluminium alloy flange sheet that cooperatively interacts and half sheet PVC flange plate, and the junction surface outer end of aluminium alloy flange sheet is provided with grab, and insert respectively in the grab of two aluminium alloy flange sheets at the two ends that C type flange is transplanted a cutting; Have the sealing joint strip groove on the junction surface of aluminium alloy flange sheet, be placed with sealing joint strip between two sealing joint strip grooves.The described flange of the utility model has been set up the sealing joint strip groove of placing sealing joint strip on the aluminum alloy surface of contact, original " connecing firmly " changed into " soft connecing ", has improved sealing; And need not get into the jointing gluing of airduct inside to two flange body; Artificial, cost of material have been reduced; Improved working efficiency, solved the problem that little airduct can not advance people's gluing simultaneously, inleakage meets code requirement and does not destroy original structure.
Further, said sealing joint strip adopts 8501 type flame retardant sealant bars; Can better reduce inleakage like this and can prevent fires.
The utility model is simple in structure, design is ingenious, has solved the problem of the big and constructional difficulties of existing composite air duct adpting flange inleakage, can be adaptable across the connection of composite air duct.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-C type flange is transplanted a cutting; 2-aluminium alloy flange sheet; The 3-PVC flange plate; The 4-grab; The 5-sealing joint strip.
Embodiment
A kind of composite sheet airduct bridge cut-off adpting flange comprises that the cross section that two symmetries are joined is the flange body and the C type flange cutting 1 of U type; Flange body is made up of half sheet aluminium alloy flange sheet 2 that cooperatively interacts and half sheet PVC flange plate 3, and the junction surface outer end of aluminium alloy flange sheet 2 is provided with grab 4, and insert respectively in the grab 4 of two aluminium alloy flange sheets 2 at the two ends of C type flange cutting 1; Have the sealing joint strip groove on the junction surface of aluminium alloy flange sheet 2, be placed with sealing joint strip 5 between two sealing joint strip grooves.Said sealing joint strip 5 adopts 8501 type flame retardant sealant bars.
Claims (2)
