Abstract
The utility model discloses an assembled ventilation pipe which comprises a pipe, a flange and a socket. The utility model is characterized in that: a plate (2) is jointed to form into a pipe body with rectangular cross-sections, four edges and corners of the pipe body are wrapped with corner protection plates (3); both ends of the pipe body are connected with internal or external insertion flange (1), or are connected with an internal insertion head (5) or an external insertion casing (4). The utility model has the advantages that the utility model has simple production, can be produced in a bunch and quantitative and specification-customized mode, can also be made on-site assemblies, has no need of separate molding; has light weight, high strength, burning resistance, heat insulation, corrosion resistance, no distortion, no cracks; and is applicable to ventilating pipes, flues, pipes for central air conditioners in the building.
Description
The utility model relates to the pipeline of ventilation equipment, particularly the assembly type ventilation duct.
Ventilation duct of the prior art mainly exists following problem:
From material, three kinds on metal, glass fibre reinforced plastics, cement arranged.The pipeline of metal species exists easy-to-rust, short defective of life-span; Inflammable, yielding deficiency that fiber reinforced plastic pipe exists; The shortcoming of too heavy, the easy be full of cracks of cement class pipeline, encapsulation difference.On production technology, existing production technology is general to adopt prefabricated supporting mould, manual pasting, and cost height, efficient are low, are difficult to form and produce in batches.
The purpose of this utility model provides the assembly type ventilation duct of advantages such as a kind ofly having intensity height, good toughness, do not chap, do not burn, light weight, life-span are long.
Above-mentioned purpose of the present utility model is to realize by such technological scheme, it is a kind of assembly type ventilation duct, comprise pipeline, flange and grafting cover, it is characterized in that: form the body that the cross section is a rectangle by board material splice, be surrounded by corner protector sheet material on four corner angle limits of body; The two ends of body connect with interior or outer plug-in type flange plate, or connect with interior connection-peg or the outer cover of pegging graft.
Said structure of the present utility model can further specify by the embodiment that accompanying drawing provides.
The utility model has following accompanying drawing:
Accompanying drawing 1 is the utility model embodiment 1 a structural representation;
Accompanying drawing 2 is the utility model embodiment 2 a structural representation;
Accompanying drawing 3-6 is a modular construction schematic representation of the present utility model.
Referring to accompanying drawing: the assembly type ventilation duct among the figure, comprise pipeline, flange and grafting cover, it is characterized in that: form the body that the cross section is a rectangle by sheet material 2 splicings, be surrounded by corner protector sheet material 3 on four corner angle limits of body; The two ends of body are connected with interior or outer plug-in type flange plate 1, or are connected with interior connection-peg 5 or the outer cover 4 of pegging graft.
In embodiment 1 as shown in Figure 1, the two ends of ventilation duct have interior plug-in type flange 1, and flange is spliced structure, promptly by as shown in Figure 5 four right angle plate adhesions and constitute, have 8-12 connecting hole 6 on the flange plate.
In embodiment 2 as shown in Figure 2, an end of ventilation duct is interior connection-peg 5, and the other end is the outer cover 4 of pegging graft.
The utility model is owing to the advantage that described structure has is: but it is quantitatively fixed to make simple batch production Specification is produced, but also Assembling needs independent molding, the mechanization production efficient height of member, structure The cost of transportation of part is low, also has light weight, intensity height, fire-retardant, heat insulation, anticorrosion, indeformable, anti-Water, do not chap, cost is low, the added value advantages of higher is a kind of building ventilation pipeline, flue, central authorities The substitute products of air-conditioning duct etc.
