Abstract
The utility model relates to a combined air duct. The combined air duct is formed by sequentially connecting a plurality of duct body units in series. A ribbed plate is connected to the middle portion of the joint of two adjacent glass magnesium plates and located on the inner side of each duct body unit through glue, every two adjacent duct body units are connected through angle iron, the angle iron is fixedly connected with the duct body units through rivets or screws, adhesive tape is bonded at the external joints between the duct body units, and glue layers are arranged on the adhesive tape. The combined air duct is simple in structure, convenient and fast to assemble and disassemble, firm in connection, and capable of saving material cost, effectively avoiding cracking and prolonging the service life.
Description
Technical field
The utility model relates to the ventilation duct field, relates in particular to a kind of combined flue pipe, is applicable to fire control smoke exhausting airduct, the wind pipe of central air-conditioning of construction engineering.
Technical background
The amount of Modern City Building application ventilation duct is increasing, traditional airduct material as galvanized steel plain sheet 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 also have after installing 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, 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 increased year by year, conventional glass magnesium airduct is installed practical flange and is connected, be prone to airduct cracking, leak out, even scaling obscission, 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, used the L-type aluminum alloy link with groove, and glass magnesium plate is installed in groove, is aided with glue and fixes, 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 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, for convenience detach, saves the combined flue pipe of cost of material.
The technological scheme that the utility model is taked is: a kind of combined flue pipe, be connected in series successively to be communicated with by a plurality of bodys unit and form, it is characterized in that: the seam stage casing of the adjacent glass magnesium of described body unit inside plate is connected with floor through glue, between two adjacent body unit, through angle bar, connect, angle bar is fixedly connected with the body unit through rivet or screw, outer seam crossing between the body unit posts adhesive plaster, and adhesive plaster is provided with glue layer.
Further, described body unit is gluedd joint by polylith glass magnesium plate or nail joint is formed by connecting, and the outer seam crossing of adjacent glass magnesium plate posts adhesive plaster, and adhesive plaster is provided with glue layer.
Further, described floor is glass magnesium plate.
Further, the length of described angle bar is no more than body length.
Further, described adhesive plaster is the high-density gridding adhesive plaster.
Further, described glue layer is the inorganic glue water layer.
The utility model takes the beneficial effect of above scheme to be:
1, all seam crossings in the glass magnesium plate of the combined flue pipe outside post the high-density gridding adhesive plaster, and are coated with the inorganic glue water layer on adhesive plaster, glue infiltration, the curing rear integral body that forms, replace metal flange, can effectively avoid cracking, extend the working life of product, save cost and space.
2, adopt glue to increase body intensity with the fixing body in the stage casing of floor side seams in body of material, between body, use shorter L-type angle bar to rivet or nail joint, saved consumption and the cost of angle bar.
3, 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.
The accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Fig. 2 is main sectional view of the present utility model.
Fig. 3 is left view of the present utility model.
In figure: airduct unit 1, adhesive tape 2, floor 3, angle bar 4, screw 5.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Shown in Fig. 1-3, a kind of rectangle combined flue pipe comprises airduct unit 1, adhesive tape 2, plate 3, angle bar 4, screw 5.The airduct unit surrounds rectangular tubular by the glass magnesium plate of 4 same sizes in the mode of nail joint or splicing, and the floor glue fixed of the middle cracked ends of the inseam of adjacent glass magnesium plate and glass magnesium sheet material matter is fixed; Four jiaos of places of two adjacent airduct unit inside are connected with respectively the right angle angle bar, and two right angle faces of described right angle angle bar are fixed on the fitting surface of two airduct unit through screw or rivet respectively.
The method of construction of rectangle combined flue pipe is:
(1) the glass magnesium plate that will be cut to given size glueds joint or the orthogonal body of nail joint.
(2) at the bonding deep floor of inorganic glue for stage casing of the interior adjacent glass magnesium plate seam of body unit, and on the glass magnesium plate seam in the outside, body unit rubberized fabric, and apply glue on adhesive plaster, place to be infiltratedly, air-dry, make the body unit.
(3) at the interior side seams established angle iron of the described body of step (2) unit, half is placed in body inside angle bar, remainder protruded tube external body, and with rivet or screw, two fitting surfaces of angle bar are fixed on the madial wall of body unit; Body unit described in another step (2) is connected on this body unit along the angle bar cover, and with rivet or screw, angle bar is fixed with it.
(4) content of repeating step (3), until splicing reaches the combined flue pipe of construction length requirement.
(5) all seam crossings between each airduct unit are taped, and on adhesive tape cementing, to be infiltrated, air-dry.
In the specific implementation, according to varying environment and place, need different in nature cross section as trapezoidal, circular etc., when construction, relate to mode that outer side seams used adhesive tape to be connected with glue all in this patent protection domain.
