Compared with the prior art, the flue capable of preventing the leakage has the advantages of being simple in structure, innovative, unique, convenient, simple and quick in installation and maintenance, reliable in performance, high in safety, remarkable in effect of preventing smoke leakage and water leakage and the like.

Description

But a kind of flue of antiseep

Technical field

But the utility model relates to a kind of flue of antiseep, belongs to flue construction technology technical field.

Background technology

Current social development is rapid, the demand of building trade not only is confined to live, but to satisfying all kinds of crowd demand's directions; The style varied development, and for this household requirement of chimney, its effect singly has not been smoke evacuation; More will pay attention to attractive in appearance and practically, in chimney history in the past, we see the dew cigarette; Percolating water is repaired problems such as difficulty, causes user's discontented and psychological shade; Traditional method is that the flue interface is located at floor plates central authorities, is that flue seam and floor is integrated like this, but has also left over a lot of problems; At first; Seam crossing concreting leakiness, its seal degree can not guarantee, cause water inside and outside seam crossing inflow flue pipe; The pipe outside can detect the seepage floor, but the water in the pipe just is difficult for detecting particular location; Secondly, the workman loads and unloads inconvenience, and the workman is inconvenient when connecting up and down flue pipe, causes easily becoming flexible, and flue seam and floor are built and be one, and encountering problems to cut refitting, and expensive effort influences attractive in appearance again, so the utility model solves the problems of the technologies described above.

Summary of the invention

The purpose of the utility model is: but the flue of convenient simple and direct, the effective leakproof cigarette of a kind of simple in structure, safe and reliable, installation and maintenance, anti-a kind of antiseep of leaking is provided, to overcome the deficiency of prior art.

The utility model is to be constructed as follows: but a kind of flue of antiseep; Comprise floor; In floor, be provided with lower floor's flue; A template is installed between the bottom surface of floor and lower floor's flue, and the gap pouring between floor and lower floor's flue has concrete, and lower floor's flue is connected with the upper strata flue through angle steel.

The seam crossing of lower floor's flue and upper strata flue is arranged on 6～14cm place, floor top, and seam crossing is added with cement paste.

The concrete upper surface that pour gap between floor and lower floor's flue is the inclined-plane, and this inclined-plane tilts from the upper surface of lower floor's flue to floor.

Owing to adopted technique scheme, when using the utility model, hair is beaten, cut a hole to floor section cutter, lower floor's flue is installed; A template is installed between the bottom surface of floor and lower floor's flue, then layering in the gap of flue and floor poured concrete, water first floor earlier, begin from the floor bottom surface with C20 expansion pea gravel concreten; Water 1/2nd thick places of about floor, closely knit with plugging in pricker again, treat the final set of first floor concrete after; Building the second layer, building to more than the floor topping 1 centimetre, pricker is closely knit with inserting; And do the gradient of an i=10%, and quite high 1 centimetre, 10 centimetres of lengths of grade; Again the upper strata flue is alignd with the lower floor flue, and detect its verticality, after the straightening; Butt joint flue, the seam two-layer model of using up and down are welded into the shutoff of " T " font as the angle steel 7 of 40*20*4, and obturage with polymer water mud; Compared with prior art, that the utility model not only has is simple in structure, the innovation unique, the convenient simple and direct advantage of installation and maintenance, and has advantages such as dependable performance, safe, leakproof cigarette, waterproof effect are obvious.

Description of reference numerals: the 1-floor, 2-lower floor flue, 3-props up template, 4-concrete, 5-angle steel, 6-upper strata flue, 7-seam crossing, 8-cement paste.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.

The enforcement of the utility model: but a kind of flue of antiseep, shown in Fig. 1～2, but a kind of flue of antiseep; Comprise floor 1; In floor 1, be provided with lower floor's flue 2, a template 3 is installed between the bottom surface of floor 1 and lower floor's flue 2, a template 3 is used for preventing that the concrete that waters from dropping; Concrete 4 has been poured in gap between floor 1 and lower floor's flue 2, and lower floor's flue 2 is connected with upper strata flue 6 through angle steel 5;

Lower floor's flue 2 is arranged on 6～14cm place, floor 1 top with the seam crossing 7 of upper strata flue 6, and seam crossing is added with cement paste 8, and it is not tight to do concrete 4 leakiness, the seam that effectively prevent owing to 1 on seam crossing 7 and floor like this; The water that causes infiltrates or inflow flue pipe inboard; Make seam crossing 7 be higher than floor face, the water on the floor 1 can not blow back into flue, has solved the inconvenient operation at the floor center-line joint; The workman can be squatted down with regard to the fastening flue seam of ability; And than in the middle of the plate or other position conveniently assemble and disassembles, floor 1, has alleviated greatly to water to smash and has been difficult for closely knit possibility because jointless interference with the flue intersection.

The upper surface of the concrete 4 that pour the gap between floor 1 and lower floor's flue 2 is domatic for of tilting to floor 1 upper surface from lower floor's flue 2.

When the utility model is implemented, at first hair is beaten, cut a hole to floor 1 section cutter, installation lower floor flue 2 is equipped with between the bottom surface of floor 1 and lower floor's flue 2 and props up a template 3; Layering is at lower floor's flue 2 gap concreting 4 with floor 1 then, and what concrete 4 adopted is C20 expansion pea gravel concreten, when beginning to build first floor, the C20 pea gravel concreten that expands is begun from 1 layer of bottom surface of floor; Water 1/2nd thick places of about floor 1, pricker is closely knit with inserting, treat 3 final set of first floor concrete after; Building the second layer, building to more than floor 1 surface layer 1 centimetre, pricker is closely knit with inserting; The way of placement layer by layer more effectively guarantees concrete compaction between floor 1 and tube wall, and does the gradient (the i.e. percentage of 2 depth displacement and its horizontal range of an i=10%; Its design formulas is following: the gradient=(depth displacement/horizontal range) x100%), the slope is high 1 centimetre, 10 centimetres of lengths of grade; The effect of building out the slope is, the first, even if there is one deck flue tube wall that water is arranged outward; The slope also can make the outer water of tube wall flow on the floor plates along the ramp, and can not flow to down one deck along tube wall, influences other floors; The second, water is arranged on the floor plates immediately, but because seam is higher than 6～14 centimetres of floor plates, and the gradient is arranged, so can not infiltrate in the flue seam; The 3rd, the sloping is done in floor plates and flue contact position, rather than the right angle, more difficult ponding.

Last upper strata flue 6 is arranged on 6～14cm place, floor 1 top; Align upper strata flue 6 this moment again with lower floor flue 2, and detect its verticality, after the straightening; The butt joint flue; The seam two-layer model of using up and down is welded into the shutoff of " T " font as the angle steel 7 of 40*20*4, and obturages complete operation with polymer water mud.
