Abstract
The utility model relates to a kind of smoke exhaust pipe, especially a kind of splice type smoke exhaust pipe.This airduct comprises top board, base plate, left plate and right plate, described top board and base plate comprise the sheet material of a level respectively, bend inwards at two lateral edges places of sheet material formation one kink respectively, the plate plane of kink and level is fitted, and the free end of kink is bent to form a vertical component effect again to perpendicular to sheet material place in-plane; The vertical component effect of top board and base plate is oppositely arranged, and described left plate and right plate are individually fixed on the vertical component effect of corresponding top board and base plate.Of the present utility model in transport with when depositing, deposit with the form that sheet material is stacking, the space greatly reducing transport and deposit, the cost reducing transport and deposit, the geometry position limiting structure between sheet material is formed when mounted by bending sheets, making the controlled shape of the formation rule when splicing between sheet material, improve the precision that pipeline is shaping.
Description
Technical field
The utility model relates to a kind of smoke exhaust pipe, especially a kind of splice type smoke exhaust pipe.
Background technology
Smoke exhaust pipe is that connecting fan carries out the ventilation passageway of intake and exhaust to indoor and outdoor, realize to indoor-outdoor air exchange, smog comparatively overall situation or fire time can as early as possible by smog discharge, with the air quality in holding chamber and visibility.Existing smoke exhaust pipe is generally customization, uses iron sheet to make square or circular pipe with predetermined length, then installs in precalculated position.Because existing smoke exhaust pipe is prefabricated, all need to take larger space having manufactured later transport and deposited, and easily suffer crimp.Existing settling mode is to job site by conveying sheet, four sheet materials to be connected by connector in edge as four planes up and down of pipeline or welds, form rectangular duct, because the sheet material at four sides is plane, be difficult to keep the verticality in two adjacent faces when edge connects, construction precision cannot ensure, the through hole that the problem that precision is low easily causes pipeline and body of wall to offer can not effectively coordinate.
Utility model content
The utility model provides one can site operation, can ensure again the splice type smoke exhaust pipe of the geometrical relationship between sheet material.
To achieve these goals, the utility model adopts following technical scheme:
Comprise top board, base plate, left plate and right plate, its improvement is: described top board and base plate comprise the sheet material of a level respectively, bend inwards at two lateral edges places of sheet material formation one kink respectively, the plate plane of kink and level is fitted, and the free end of kink is bent to form a vertical component effect again to perpendicular to sheet material place in-plane; The vertical component effect of top board and base plate is oppositely arranged, and described left plate and right plate are individually fixed on the vertical component effect of corresponding top board and base plate.
Preferably, the bending place between the sheet material of described top board and the level of base plate and kink is provided with two and bends groove.
Preferably, the bending place between described kink and vertical component effect is provided with one and bends groove.
Preferably, described left plate and right plate comprise vertical plane portion and respectively respectively at the sticking part that lower edges place of vertical plane portion bends laterally.
Preferably, be provided with one between described vertical plane portion and sticking part and bend groove.
Owing to have employed said structure, splice type smoke exhaust pipe of the present utility model splices composition side plate by using scab, then side plate is carried out splicing composition smoke exhaust pipe, and in transport with when depositing, deposit with the form that sheet material is stacking, the space greatly reducing transport and deposit, the cost reducing transport and deposit, the geometry position limiting structure between sheet material is formed when mounted by bending sheets, making the controlled shape of the formation rule when splicing between sheet material, improve the precision that pipeline is shaping.

Detailed description of the invention
As Figure 1-Figure 5, the splice type smoke exhaust pipe of the utility model embodiment comprises top board 1, base plate 2, left plate 3 and right plate 4, described top board 1 and base plate 2 comprise the sheet material 5 of a level respectively, bend inwards at two lateral edges places of sheet material 5 formation one kink 6 respectively, kink 6 is fitted with sheet material 5 plane of level, and the free end of kink 6 is bent to form a vertical component effect 7 again to perpendicular to sheet material 5 place in-plane; The vertical component effect 7 of top board 1 and base plate 2 is oppositely arranged, and described left plate 3 and right plate 4 are individually fixed on the vertical component effect 7 of corresponding top board 1 and base plate 2.
Because sheet material is generally metal material, for the ease of operating dings, especially improve the angle precision of the sheet material after bending, in the present embodiment, the bending place between the sheet material of described top board 1 and the level of base plate 2 and kink 6 is provided with two and bends groove 8.
In the present embodiment, the bending place between described kink 6 and vertical component effect 7 is provided with one and bends groove 9.
In the present embodiment, described left plate 3 and right plate 4 comprise vertical plane portion 10 and respectively respectively at the sticking part 11 that lower edges place of vertical plane portion 10 bends laterally.
Same, for the ease of to dings operation, especially improve the angle precision of the sheet material after bending, in the present embodiment, be provided with one between described vertical plane portion 10 and sticking part 11 and bend groove 12.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model manual and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
