Description
Technical field:
The utility model relates to a kind of ventilating duct, relates in particular to a kind of ventilating duct that is used to carry warm braw in the building that is installed on.
Background technology:
In the prior art, be used to carry the ventilating duct ubiquity of air-conditioning warm braw many deficiencies, CN2510573 number Chinese utility model patent as notice of authorization on the 11st in China national Department of Intellectual Property September in 2002, disclosing a kind of is the ventilating duct of carrier with the foam heat-insulating board, its foam heat-insulating board is to be carrier with polystyrene foam warming plate or polyurethane foam insulation plate, on two surfaces of foam heat-insulating board, respectively compound layer of glass strengthens the magnesium oxychloride cement plate, and the glass fiber of foam heat-insulating board and its both sides strengthens the magnesium oxychloride cement plate and forms blast pipe board together.The junction of each blast pipe board adds the adhesive linkage of making that one deck adopts high-strength adhesive.Although this ventilating duct prior art relatively has certain progress, have heat insulation effect preferably, but shortcoming also is very tangible: owing to connect by bonding way between each piece blast pipe board, extremely inconvenient when not only installing and using, need coat cementing agent earlier, accurately compress behind the location then, it is firm that it is connected, thereby complex operation step again, workload is big, and it is insecure to bond, and throws off easily, has shortened its application life.
The utility model content:
The technical problems to be solved in the utility model is, overcomes the deficiency of above-mentioned prior art, and a kind of improved ventilating duct is provided, and it is not only easy for installation, saves workload, and is connected firmly between each plate, and steady quality is reliable, long service life.
Improved ventilating duct according to the utility model provides is combined by the polylith blast pipe board, and each piece blast pipe board links together by the interface arrangment that cooperatively interacts.
The improved ventilating duct that provides according to the utility model also possesses following attached technical characterictic:
The cross sectional shape of described ventilating duct is a rectangle, and described blast pipe board comprises two transverse slats that are parallel to each other and two stringer boards that are connected described two transverse slats; The two ends of described transverse slat are formed with tenon, and the two ends of described stringer board are formed with the tongue-and-groove that can cooperate with described tenon, and described transverse slat and stringer board cooperate together by described tenon and described tongue-and-groove.
The cross sectional shape of described tenon and described tongue-and-groove is a swallow-tail form.The base of described swallow-tail form tenon and tongue-and-groove and the angle of hypotenuse are 60 to 80 degree.
In a kind of preferred embodiment that the utility model provides, the base of described swallow-tail form tenon and tongue-and-groove and the angle of hypotenuse are 75 degree.
Described transverse slat and stringer board all are made of warming plate and the fireprotection layer that fits in described warming plate both sides, and the thickness of described warming plate is 10-30mm; The height of described swallow-tail form tenon is 4 to 14mm, and the height of described tongue-and-groove is 6 to 18mm.In a kind of preferred embodiment that the utility model provides, the thickness of described warming plate is 15mm, and the height of described swallow-tail form tenon is 7mm, and the height of described tongue-and-groove is 9mm.
The improved ventilating duct that provides according to the utility model owing to realize connection between each warming plate only needing the tenon of a warming plate is inserted in the corresponding tongue-and-groove of another warming plate during installation by the cooperation of tenon and tongue-and-groove, can link together the two.Therefore it is very convenient not only to install, and compares with the splicing of prior art, and workload reduces greatly, has reduced installation cost; And be connected firmly between each warming plate, make whole ventilating duct steady quality reliable, prolong its application life.
Description of drawings:
The cross section view of the improved ventilating duct that provides according to the utility model is provided Fig. 1;
Fig. 2 is the A place zoomed-in view of Fig. 1, the clear fit structure that shows tenon and tongue-and-groove among the figure.
The specific embodiment:
Referring to Fig. 1, the improved ventilating duct according to the utility model provides is combined by polylith blast pipe board 10, and each piece blast pipe board 10 links together by the interface arrangment that cooperatively interacts.
As shown in fig. 1, in the preferred embodiment that the utility model provides, the cross sectional shape of described ventilating duct is a rectangle, and described blast pipe board 10 comprises two transverse slats 1 that are parallel to each other and two stringer boards, 2 compositions that are connected described two transverse slats 1; The two ends of described transverse slat 1 are formed with tenon 11, and the two ends of described stringer board 2 are formed with the tongue-and-groove 21 that can cooperate with described tenon 11, and described transverse slat 1 and stringer board 2 cooperate together by described tenon 11 and described tongue-and-groove 21.Only need during installation described tenon 11 is inserted described tongue-and-groove 21, transverse slat 1 and stringer board 2 can be linked together, steps such as adhesive means gluing, location, bonding in the prior art have been saved, not only simple to operation, and connect more solid and reliablely than adhesive means, prolonged the application life of ventilating duct.
As shown in fig. 1, described transverse slat 1 and stringer board 2 all are made of warming plate 12,22 and the fireprotection layer 13,23 that fits in described warming plate 12,22 both sides, described warming plate 12,22 can adopt polystyrene foam warming plate or polyurethane foam insulation plate, and its thickness is 10-30mm; Described fireprotection layer 13,23 can adopt high-intensity inorganic adhesive, also can adopt other fire proofing material.
As shown in Fig. 1,2, the cross sectional shape of described tenon 1 and described tongue-and-groove 21 is a swallow-tail form.The base of described swallow-tail form tenon 11 and tongue-and-groove 21 and the angle of hypotenuse (being the angle α among Fig. 2) are 60 to 80 degree.In the preferred embodiment that the utility model provides, the base of described swallow-tail form tenon 11 and tongue-and-groove 21 and the angle of hypotenuse are 75 degree.Adopt the structure of swallow-tail form, make between described transverse slat 1 and the stringer board 2 closely, link together reliably.The height of described swallow-tail form tenon 11 is 4 to 14mm, and the height of described tongue-and-groove 21 (the length b among Fig. 2) is 6 to 18mm.When the height of swallow-tail form tenon and tongue-and-groove and base and hypotenuse be positioned at above-mentioned number range the time, can guarantee that described transverse slat 1 and stringer board 2 are connected firmly, can guarantee that again transverse slat 1 and stringer board 2 all have enough strength and stiffness.Its optimum value is: the base of described swallow-tail form tenon 11 and tongue-and-groove 21 and the angle of hypotenuse are 75 degree, and the thickness of described warming plate 12,22 is 15mm, and the height of described swallow-tail form tenon 11 and tongue-and-groove 21 is 9mm.
Above preferred embodiment is only for the usefulness that the utility model is described; those of ordinary skill in the related art; under the guidance that does not break away from the utility model spirit, also can make various distortion and conversion, so all technical schemes that are equal to all belong to protection domain of the present utility model.
