Abstract
The utility model discloses a combined type ventilating pipeline, which is provided with a hollow square pipeline formed by substrates, wherein at least one fixed support plate is fixedly clung to the periphery of the inner wall of the pipeline, and ventilating holes are formed on the fixed support plate in the axial direction; stiffening ribs are arranged at the corners of the inner wall of the pipeline in the axial direction, and the cross sections of the stiffening ribs are triangular, rectangular, L-shaped and the like; and the fixed support plate can take the shapes of a Chinese character 'ri', 'tian', 'mu' and the like. The combined type ventilating pipeline has the advantages of firmness, stability, simple structure and convenience and rapidness in installation.
Description
Technical field
The utility model relates to a kind of constructional materials, particularly a kind of indoor ventilating duct.
Background technology
Ventilation is the important health technology of dust in the control room, pernicious gas or steam and the indoor microclimate of improvement.It mainly acts on and is to discharge pollute or moist, the overheated or cold excessively air of indoor band, sends into extraneous clean air.So just need a kind of ventilating duct of more stable and stronger, can guarantee indoor good environment for a long time.
Currently used room ventilation pipeline is made of substrate, fixed strip, and fixed strip is arranged at the angle that any adjacent two substrates forms, and bonding or riveted is connected between fixed strip and adjacent two substrates.Since pipeline may very long whole like this ventilating duct the just not enough more stable and stronger of structure, deform easily.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of stable combined type ventilating duct firm in structure.
For solving the problems of the technologies described above, combined type ventilating duct of the present utility model has the tetragonal pipeline of the hollow that is made of substrate, is close to inner-walls of duct and is fixed with at least one fixed support plate all around, and fixed support plate axially has gravity vent.
Have the fixed support plate of gravity vent by installation, make whole combined type ventilating duct more stable and stronger.Whole pipe is simple in structure, and it is convenient to install.

The specific embodiment
First kind of embodiment structural representation of combined type ventilating duct shown in Figure 1, the tetragonal pipeline 1 with the hollow that constitutes by substrate, pipeline 1 middle part is fixed with fixed support plate 3, and fixed support plate 3 axially has gravity vent 4.Wherein fixed support plate 3 is " day " font, as shown in Figure 4.
Second kind of embodiment structural representation of combined type ventilating duct shown in Figure 2 is close to pipeline 1 inwall and is fixed with a fixed support plate 3 in the middle part all around, and pipeline 1 inwall bight axially is provided with reinforcing rib 2.Wherein fixed support plate 3 is " day " font, and the shape of cross section of reinforcing rib 2 is " L " shape, as shown in figure 11.Such purpose is if pipeline is longer, and reinforcing rib can play good fixation.
The third embodiment structural representation of combined type ventilating duct shown in Figure 3, the middle part is fixed with a fixed support plate 3 around being close to pipeline 1 inwall, have at least an end also to be fixed with fixed support plate 3 at pipeline 1 two ends, wherein pipeline 1 inwall bight axially is provided with reinforcing rib 2.Wherein fixed support plate 3 is " day " font, and the shape of cross section of reinforcing rib 2 is a triangle, as shown in Figure 9.Make whole pipe more stable and stronger more like this.
Fixed support plate 3 described in above-mentioned three kinds of embodiments can change sphere of movements for the elephants shape as shown in Figure 5 or " order " or Fig. 6, Fig. 7, figure shown in Figure 8 into.The shape of cross section of reinforcing rib 2 also can change rectangle as shown in figure 10 into.But the shape of fixed support plate 3 is not limited to Fig. 4, Fig. 5, Fig. 6, Fig. 7, figure shown in Figure 8, and the conversion of gravity vent shape all drops within the scope of the utility model protection.The shape of cross section of reinforcing rib 2 also is not limited to Fig. 9, Figure 10, figure shown in Figure 11, is suitable for pipeline 1 bight fixed shape also all within the scope of the utility model protection.
