Abstract
The utility model relates to a combined ventilation air duct, which comprises a duct body enclosed by a plurality of side plates, wherein angle iron is connected between internal sides of two adjacent side plates, screws are connected between the side plates and the angle iron, adhesive tapes are bound at external joint seams of the adjacent side plates of the duct body and a glue layer is disposed on the tapes. The combined ventilation air duct is simple in structure, and convenient in assembly and removal, has stable and firm connecting structures and relatively high strength and anti-bending strength and can satisfy use of high-pressure, middle-pressure and low-pressure air systems.
Description
Technical field
The utility model relates to building ventilation pipeline, relates in particular to a kind of combined ventilating airduct for fire control smoke exhausting airduct, wind pipe of central air-conditioning.
Technical background
The amount of Modern City Building application ventilation duct is increasing, traditional airduct material is if galvanized steel plain sheet is due to the rise of this several years price of steel product and the rise of cost of labor, make fabricating cost more and more higher, and also to do the construction of thermal insulation layer after installing, not only increased cost, and after installing, also have and be not good at causing maintenance cost because of insulation, huge waste of air-conditioning cold flow etc. problem, can not meet the market demand of rapid growth and people to energy-conservation requirement.Glass magnesium airduct has that intensity is high, lightweight, fireproof performance is good, comprehensive cost low cost and other advantages, in addition itself need not be incubated by secondary, agree with the trend of energy-saving and environmental protection, the market share in ventilation duct field is the situation increasing year by year, conventional glass magnesium airduct is installed practical flange and is connected, be prone to airduct cracking, leak out, even scaling obscission, has had a strong impact on the market application foreground of glass magnesium airduct.The disclosed a kind of moistureproof fire resistant air-duct of the patent No. 200920147388, is used the L-type aluminum alloy link with groove, and glass magnesium plate is installed in groove, is aided with glue and fixes, and outside adds flange and fixes.The shortcoming of this mounting type is that aluminum alloy material consumption is more, and is unfavorable for detachable maintaining, and using flange to connect increases cost and weight.
Summary of the invention
The purpose of this utility model 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 utility model is taked is:
A combined ventilating airduct, comprises the body being surrounded by some side plates, between two adjacent side plates inner sides, is connected with angle bar, between side plate and angle bar, is connected with screw, 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 high-density gridding adhesive plaster.
Further again, described glue layer is aluminium magnesia inorganic glue water layer.
The utility model 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 A level is not fired building materials; Internal and external layer is glass fibre reinforced layer, has higher intensity and bending strength, can meet the use of high, medium and low compressed-air system, and lighter weight, reduces building load.
2, between the outer glass magnesium plate of Cracking Proof Combined Fibreglass Air Hose, high-density gridding adhesive plaster is posted at connecting sewing place, and on adhesive plaster, be coated with inorganic glue water layer, and the material of glue is identical with glass magnesium plate substrate, and after glue permeates, solidifies, shape is in aggregates, can effectively avoid cracking, extend the working life of product.The contemporary flanged connecting structure that replaced, provides cost savings and space, elegant in appearance.
3, adopt inner side L-type angle bar attachment screw or rivet to fix, the Placement that outside belt is fixing, assembling is simple, saves manpower, is also 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 using process.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure: glass magnesium plate 1, angle bar 2, screw 3, adhesive tape 4.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Shown in Fig. 1, a kind of combined ventilating airduct comprises the rectangular tube being 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, between two vertical adjacent glass magnesium plate inner sides, be provided with the right angle angle bar 2 identical with airduct length, angle bar 2 and side sheet room are by screw reinforcement by connection, outside rectangular tube, all seam crossings all post high-density fiber adhesive plaster 4, scribble the inorganic glue of aluminium magnesia on adhesive plaster 4.
Specific construction mode is:
(1), cut angle bar and glass magnesium plate: according to the size of actual airduct, cut the angle bar of corresponding length, according to size, cut the glass magnesium plate of given size.
(2), lay 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 of angle bar of well cutting are mounted on the side plate of bottom surface, one outside fitting surface of angle bar coordinates with end face on the side plate of bottom surface, another outside fitting surface aligns with the side of bottom surface side plate, from side plate back, be screwed into screw, guarantee that every block of glass magnesium plate all with between angle bar has and is no less than 2 screw fastenings and is connected.
(4), both sides side plate is installed: glass magnesium plate is vertical near placement with bottom surface side plate, and the side of glass magnesium plate is concordant with the bottom surface of bottom surface side plate, then with being no less than 2 screws, glass magnesium plate is fixed on the fitting surface that angle bar is mated.Repeat this step content, until the whole installations of both sides side plate.
(5) top side plate is installed: the mode according to step (2) and step (3) is laid top side plate, and two angle bar are installed on the side plate of top, after again the end face of the angle bar of the end face on the side plate of top and both sides side plate is concordant, be screwed, form rectangular tube.
(6) paste high-density fiber adhesive tape: one deck high-density fiber adhesive tape is pasted at places, connection gap all outside the rectangular tube having completed, and on adhesive tape, is coated with the inorganic glue of one deck aluminium magnesia, treats glue infiltration, solidifies.
In the specific implementation, according to varying environment and place, need different in nature cross section as trapezoidal, circular etc., when construction, relate to outer side seams and use mode that adhesive tape is connected with glue all in this patent protection domain.
