Abstract
The invention relates to a combined ventilating duct. The combined ventilating duct comprises a duct body formed by a plurality of lateral plates in a surrounding mode, angle iron is connected between the inner sides of every two adjacent lateral plates, screws are connected between every lateral plate and the angle iron, adhesive tapes are attached to the outer connecting seam positions of the adjacent lateral plates of the duct body, and glue layers are arranged on the adhesive tapes. The combined ventilating duct is simple in structure, convenient to assemble and detach, firm and reliable in connecting structure, high in strength and bending strength, and capable of being applied to high-pressure, mediate-pressure and low-pressure air systems.
Description
Technical field
The present invention relates to the building ventilation pipeline, relate in particular to a kind of combined ventilating airduct for fire-fighting smoke exhaust pipe, central air-conditioner airduct.
Technical background
The amount of modern city Application in Building ventilation duct is increasing, traditional airduct material such as galvanized steel plain sheet are because the rise of this several years price of steel product and the rise of cost of labor, make that fabricating cost is more and more higher, and also to do the construction of thermal insulation layer after installing, not only increased cost, and also have after installing because of insulation and be not good at causing maintenance cost, huge waste of air-conditioning cold flow etc. problem can not satisfy the market demand of quick growth and people to energy-conservation requirement.Glass magnesium airduct have the intensity height, in light weight, fireproof performance good, the comprehensive cost low cost and other advantages, itself need not be incubated by secondary in addition, agree with the trend of energy-saving and environmental protection, the market share in the ventilation duct field is the situation that increases year by year, conventional glass magnesium airduct is installed practical flange and is connected, be prone to airduct cracking, leak out, even the scaling obscission, had a strong impact on the market application foreground of glass magnesium airduct.The patent No. 200920147388 disclosed a kind of moistureproof fire resistant air-duct are used the L type aluminum alloy link of being with groove, and glass magnesium plate is installed in the groove, are aided with glue and fix, and the outside adds flange and fixes.The shortcoming of this mounting type is that the aluminum alloy material consumption is more, and is unfavorable for the dismounting maintenance, and using flange to connect increases cost and weight.
Summary of the invention
The purpose of type of the present invention is to provide a kind of construction simple, the combined ventilation airduct of a kind of environmental protection for convenience detach.
The technological scheme that the present invention takes is:
A kind of combined ventilating airduct comprises the body that is surrounded by some side plates, is connected with angle bar between two adjacent side plate inboards, is connected with screw between side plate and angle bar, and it is characterized in that: the outer seam crossing of body adjacent side plates posts adhesive plaster, and adhesive plaster is provided with glue layer.
Further, described side plate is glass magnesium plate.
Further, described side plate is connected in sequence by polylith glass magnesium plate, and the glue seam crossing of adjacent glass magnesium plate posts adhesive plaster, and adhesive plaster is provided with glue layer.
Further, described adhesive plaster is the high-density gridding adhesive plaster.
Further again, described glue layer is aluminium magnesia inorganic glue water layer.
The present invention takes the beneficial effect of above scheme to be:
1, the glass magnesium plate of Cracking Proof Combined Fibreglass Air Hose employing magnesium oxychloride cement is base material, possesses fireproof performance, for the A level is not fired building materials; Internal and external layer is the glass fibre reinforced layer, and higher intensity and bending strength are arranged, and can satisfy the use of high, medium and low compressed-air system, and lighter weight, reduces building load.
2, connect seam crossing between the outer glass magnesium plate of Cracking Proof Combined Fibreglass Air Hose and post the high-density gridding adhesive plaster, and be coated with the inorganic glue water layer at adhesive plaster, and the material of glue is identical with glass magnesium plate substrate, the glue infiltration, solidifies the back and forms an integral body, can effectively avoid cracking, prolong the working life of product.The contemporary flanged connecting structure that replaced provides cost savings and the space, and is elegant in appearance.
3, adopt inboard L type angle bar attachment screw or rivet to fix, outside belt is fixedly coupled mode, and assembling is simple, saves manpower, also is convenient to the dismounting when maintenance or scheme change simultaneously.
4, the material of aerofoil and construction are inorganic constituents with glue, adhesive tape etc., and environmental protection can not produce harmful matter in the using process.
Description of drawings
Fig. 1 is schematic representation of the present invention.
Among the figure: glass magnesium plate 1, angle bar 2, screw 3, adhesive tape 4.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.
Shown in Figure 1, a kind of combined ventilating airduct comprises the rectangular tube that is surrounded by four blocks of side plates, described side plate is that the glass magnesium plate by some identical magnesium oxychloride cement base materials is spliced, be provided with the right angle angle bar 2 identical with airduct length between two vertical adjacent glass magnesium plate inboards, angle bar 2 and side sheet room are by the screw reinforcement by connection, all seam crossings of the rectangular tube outside all post high-density fiber adhesive plaster 4, scribble the inorganic glue of aluminium magnesia on the adhesive plaster 4.
Concrete form of construction work is:
(1), cuts angle bar and glass magnesium plate: according to the size of actual airduct, cut the angle bar of corresponding length, cut the glass magnesium plate of given size according to size.
(2), lay the bottom surface side plate: some glass magnesium plates isoplanar close alignment is arranged, be laid to the rectangular bottom surface side plate of corresponding length.
(3), angle bar is installed: two sections angle bar of well cutting are mounted on the side plate of bottom surface, one outside fitting surface of angle bar cooperates with end face on the side plate of bottom surface, another outside fitting surface aligns with the side of bottom surface side plate, be screwed into screw from the side plate back, guarantee every block of glass magnesium plate all and angle bar between have and be no less than 2 screws and be fastenedly connected.
(4), the both sides side plate is installed: glass magnesium plate is vertical near placement with the bottom surface side plate, and the side of glass magnesium plate is concordant with the bottom surface of bottom surface side plate, and usefulness is no less than 2 screws glass magnesium plate is fixed on the fitting surface that angle bar is mated again.Repeat this step content, until the whole installations of both sides side plate.
(5) the top side plate is installed: the mode according to step (2) and step (3) is laid the top side plate, and at two angle bar of top side plate installation, again with the angle bar of the end face on the side plate of top be screwed after the end face of both sides side plate is concordant, form rectangular tube.
(6) paste the high-density fiber adhesive tape: paste one deck high-density fiber adhesive tape at the place, connection slit that the rectangular tube outside of having finished is all, and be coated with the inorganic glue of layer of aluminum magnesium oxide at adhesive tape, treat the glue infiltration, solidify.
In the specific implementation, according to varying environment and place, need different in nature cross section such as trapezoidal, circle etc., when construction, relate to outer side seams use adhesive tape and glue ways of connecting all in this patent protection domain.
