Abstract
The utility model discloses a kind of ventilation duct linkage structure, comprise the flange edge two airducts mutually docked and each airduct being positioned at docking side, flange angle is connected with between two adjacent flange edges, two relative flange angles are equipped with corresponding bolt hole, two relative flange angles are fixed by the bolt through bolt hole, are provided with the sealing joint strip between the flange edge being positioned at docking between the airducts of two docking.This ventilation duct linkage structure connects the flange angle on adjacent flanges limit by arranging at airduct periphery, be bolted relative flange angle subsequently to realize the docking of airduct, each flange angle of this linkage structure all can be carried out normalization and be produced in enormous quantities, and conveniently assemble with flange edge in connection process, its connection operation is simple simultaneously, can reduce and install labor intensity, this model utility is used for ventilation duct structure field.
Description
Technical field
The utility model relates to ventilation duct field, particularly relates to a kind of ventilation duct linkage structure.
Background technique
When ventilation duct makes, according to domestic traditional construction process, between airduct, the connection of pipeline section is all got used to adopting angle steel flange to connect.Because angle steel flange connects complex procedures, the operations such as corner cut steel needs to carry out cutting off, weld, punch, brushing rust proof paint, material deterioration inside is large, time-consuming takes a lot of work, and on-the-spot processing inconvenience and lifting difficulty, make traditional this construction process can not meet the requirement of the aspects such as construction and technique at present.
Model utility content
For solving the problem, the utility model provides one easy to assembly and the simple ventilation duct linkage structure of operation.
The utility model solves the technological scheme that its technical problem adopts:
A kind of ventilation duct linkage structure, comprise the flange edge two airducts mutually docked and each airduct being positioned at docking side, flange angle is connected with between two adjacent flange edges, two relative flange angles are equipped with corresponding bolt hole, two relative flange angles are fixed by the bolt through bolt hole, are provided with the sealing joint strip between the flange edge being positioned at docking between the airducts of two docking.
Be further used as the improvement of technical solutions of the utility model, the cross section of airduct is rectangle, each flange edge and airduct one-body molded.
Be further used as the improvement of technical solutions of the utility model, the width at each flange angle equals the width of flange edge, and each flange angle is right angle frame, and the both sides at flange angle are separately fixed on two adjacent flange edges.
Be further used as the improvement of technical solutions of the utility model, outside two relative flange edges, be provided with the flange bound edge in gap between parcel two flange edge.
The beneficial effects of the utility model: this ventilation duct linkage structure connects the flange angle on adjacent flanges limit by arranging at airduct periphery, be bolted relative flange angle subsequently to realize the docking of airduct, each flange angle of this linkage structure all can be carried out normalization and be produced in enormous quantities, and conveniently assemble with flange edge in connection process, it connects operation simply simultaneously, can reduce and install labor intensity.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model embodiment overall structure schematic diagram;
Fig. 2 is the utility model embodiment airduct and flange angle connection part structural representation;
Fig. 3 is the utility model air duct structure schematic diagram.
Embodiment
With reference to Fig. 1 ~ Fig. 3, the utility model is a kind of ventilation duct linkage structure, comprise the flange edge 2 two airducts 1 mutually docked and each airduct 1 being positioned at docking side, flange angle 3 is connected with between two adjacent flange edges 2, two relative flange angles 3 are equipped with corresponding bolt hole 5, two relative flange angles 3, by being fixed through the bolt of bolt hole 5, are provided with the sealing joint strip 4 between the flange edge 2 being positioned at docking between the airducts 1 of two docking.
This ventilation duct linkage structure connects the flange angle 3 on adjacent flanges limit 2 by arranging at airduct 1 periphery, be bolted relative flange angle 3 subsequently to realize the docking of airduct 1, each flange angle 3 of this linkage structure all can be carried out normalization and be produced in enormous quantities, and conveniently assemble with flange edge 2 in connection process, it connects operation simply simultaneously, can reduce and install labor intensity.
As the utility model preferred embodiment, the cross section of airduct 1 is rectangle, and each flange edge 2 is one-body molded with airduct 1.
Each limit doubling on airduct 1, by cutting four right-angle positions of airduct 1, is obtained flange edge 2 by each flange edge 2 subsequently, and this structure is convenient to be realized, and meanwhile, reaches integrated airduct 1 and flange edge 2 realizes seamless link, can better ensure its sealability.
As the utility model preferred embodiment, the width at each flange angle 3 equals the width of flange edge 2, and each flange angle 3 is right angle frame, and the both sides at flange angle 3 are separately fixed on two adjacent flange edges 2.
The flange angle 3 of independent making is equal with the width of flange edge 2, being realized being connected by the dual-side at flange angle 3, also by arranging bolt hole on the dual-side at flange angle 3, realizing the connection with flange edge 2 by welding with flange edge 2.
As the utility model preferred embodiment, the flange bound edge 6 in parcel two flange edge 2 gaps is provided with outside two relative flange edges 2.
Flange bound edge 6 is wrapped in outside two relative flange edges 2, by flange bound edge 6 is carried out roll extrusion, can realize being tightly connected of dual-side, better ensures the sealability of airduct joint.
Certainly, the invention is not limited to above-mentioned mode of execution, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
