Abstract
The utility model discloses a ventilating air exhausting passage, comprising voltage transformation structure hoops, wherein a plate material is arranged between every two voltage transformation structure hoops to form the ventilating air exhausting passage with the hoops; and the voltage transformation structure hoops are arranged in the plate materials or outside the plate material. In the ventilating air exhausting passage, as the voltage transformation structure hoops are fixedly connected with the plate material to form the ventilating air exhausting passage, so that the deformation is not easy and the sealing effect is good, small plate materials can be selected to be assembled according to the length, so that the materials, the time and the labor are saved; and as the caliber of an inner wall of the voltage transformation structure hoop is different from that of the plate material, so that the function of the voltage transformation is achieved. The ventilating air exhausting passage can be directly assembled at the construction site, and the working efficiency is 3-6 times higher than that of the existing assembly, so that the large-scale flow line production can be realized.
Description
Technical field
The utility model relates to a kind of building exhaust equipment, particularly a kind of air extractor duct.
Background technology
Building all need be provided with shared exhast duct, and existing ventilating duct generally is to use sheet material to be assembled into pipeline, and pipeline is by wall, so the pipeline that uses the method to produce leans on the sealing problem at wall place to solve; Because ventilating duct need have the function of transformation, and existing pipeline does not possess the transformation function, and variable-pressure plate need be installed on pipeline in addition; And existing pipeline needs at least three meters the sheet material could assembly unit, when not needing three meters length, dismisses after must assembly unit good again, causes the waste of man-hour and material easily.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of this utility model is to provide a kind of air extractor duct, has that assembling is simple, sealing is high, characteristics that can transformation.
In order to achieve the above object, the technical solution of the utility model is to realize like this;
A kind of air extractor duct is characterized in that, comprises transformation structure hoop 1, is provided with sheet material 2 between per two transformation structure hoops 1, forms the air extractor duct of strap.
Described transformation structure hoop 1 is arranged on the inside or the outside of sheet material 2.
The utility model is because use transformation structure hoop 1 is fixedly connected to form air extractor duct with sheet material 2, so not yielding, good sealing effect also can be selected the assembly unit of platelet material, economical with materials and man-hour for use according to Len req; Because the caliber that the inwall caliber of transformation structure hoop 1 and sheet material 2 form is different big, so have the function of transformation; The utility model directly assembly unit at the construction field (site), operating efficiency than the high at least 3-6 of existing assembly unit doubly can realize large-scale pipeline production.
Description of drawings
Accompanying drawing is a shaft side figure of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operating principle are described in detail.
With reference to accompanying drawing, a kind of air extractor duct, comprise transformation structure hoop 1, between per two transformation structure hoops 1, be provided with sheet material 2, form the air extractor duct of strap, in the junction of transformation structure hoop 1 with sheet material 2, transformation structure hoop 1 can be arranged on the inside of sheet material 2, also transformation structure hoop 1 can be arranged on the outside of sheet material 2.
Operating principle of the present utility model is: according to the length of the actual required pipeline in scene, use a plurality of transformation structure hoops 1, be provided with sheet material 2 and form air extractor duct between per two transformation structure hoops 1.Because air extractor duct is to be assembled with sheet material 2 by several transformation structure hoops 1, not only has the function of transformation but also make the interface good seal performance, solve the problem that prior art can't seal by wall place interface, and the utility model can be selected the assembly unit of platelet material, economical with materials and man-hour for use according to Len req; The utility model directly assembly unit at the construction field (site), efficient than the high at least 3-6 of existing assembly unit doubly.
Claims (2)
