Description
Technical field
What the present invention relates to a kind of rainwater leakage prevention stretches out roofing pipe and construction method thereof, be specifically related to a kind of for going out roof drainage pipe, go out roofing penetration pipe etc. and stretch out roofing pipe and construction method thereof from the indoor rainwater leakage prevention stretched out; Belong to construction work waterproof technology of roofing field.
Background technology
Building roofing, because of under being directly exposed to rainwash, very easily produces Seepage.For this reason, usually can do waterproofing work to roofing, to guarantee the leakage-proof and seepage-proof of roofing, avoid losing within doors because rain leakage causes.But the structure of building often produces the tubing stretching out roofing, as gutter, penetration pipe etc., these tubing bring very inconvenience to the waterproof of roofing, and in engineering construction, the binding site of these tubing and roofing often becomes the problem place of seepage.
At present, the processing method of roof waterproof hidden danger phenomenon is caused to adopt the method for polyurethane water-proof layer often for stretching out roofing pipe, this method Problems existing is that tubing connects roofing by polyurethane water-proof layer, tubing and be linearly connected between roofing hole gap and roofing, contact surface is little, once waterproofing course is in generation crack, junction, just lose waterproof action, therefore the effect of waterproofing protection is comparatively fragile; The waterproof technology of roofing also had is by increasing encapsulant, going out on roofing pipe to be welded umbrella shape rain shade etc., and these modes not can solve out roofing pipe and are connected contact surface this root problem little with roofing gap.
Summary of the invention
Technical problem to be solved by this invention is: for rainwater the most scabrous in roof waterproof along stretching out the technical problem of roofing pipe (as gutter, penetration pipe etc.) with roofing hole gap leakage.
Design philosophy of the present invention is, the linear protection being changed original waterproofing course by water baffle is Double-contact surfaces protection, realizes double plane waterproof, thus guarantees to stretch out roofing pipe periphery waterproof quality.
The object of the invention is to for roof waterproof weakest link---design effectively is carried out in the connection of stretching out roofing pipe and roofing, to guarantee the leakage-proof and seepage-proof of roofing to rainwater, avoids losing within doors because rain leakage causes.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Rainwater leakage prevention stretch out a roofing pipe, comprise pipe shaft, water baffle and lower pipe shaft; Upper pipe shaft and lower pipe shaft are connected by water baffle and upper pipe shaft is connected with lower pipe shaft; Upper pipe shaft and all perpendicular settings with water baffle of lower pipe shaft; The junction of upper pipe shaft and lower pipe shaft and water baffle all seals.
The present invention is directed to roof waterproof weakest link---analyze and research in the junction of stretching out roofing pipe and roofing, devise a kind of for going out roof drainage pipe, go out roofing penetration pipe etc. and stretch out roofing pipe from the indoor rainwater leakage prevention stretched out.These technical scheme main contents are: the linear protection being changed original waterproofing course by water baffle is Double-contact surfaces protection, realizes double plane waterproof, thus guarantees to stretch out roofing pipe periphery waterproof quality.
Upper pipe shaft in the present invention, water baffle, lower pipe shaft and floor are all by casting or the processing of other technology modes, and seamless link is integral securely.
To the improvement of technical solution of the present invention, the junction of upper pipe shaft and water baffle and the junction of lower pipe shaft and water baffle are provided with floor.The floor set up in the present invention improves the intensity of stretching out roofing pipe of rainwater leakage prevention of the present invention effectively, increases the stressed of water baffle.
To the further improvement of technical solution of the present invention, the uniform setting of floor.In the present invention, floor is uniform is arranged so that water baffle uniform stressed.
Meanwhile, the invention allows for the construction method of stretching out roofing pipe of rainwater leakage prevention, comprise the steps:
1) when carrying out roof construction layer, cement mortar screeding to falls layer, insulation layer, the construction of cement mortar screeding layer, reserved stretch out rainwater leakage prevention and stretch out roofing pipe hole, hole diameter is greater than and stretches out roofing pipe diameter;
2) after the construction of cement mortar screeding layer terminates drying, roofing cement mortar levelling layer arranges coil waterproof layer; Diameter is stayed to be greater than the round breach of water baffle diameter at the periphery stretching out roofing pipe hole place;
3) in step 2 stay round indentation, there polyurethane water-proof paint to fill up except stretching out roofing pipe hole exterior domain, form polyurethane water-proof paint levelling tack coat;
4) after step 3 terminates, the lower pipe shaft that rainwater leakage prevention stretches out roofing pipe is inserted in hole by roofing, and water baffle is tightly pasted on the levelling tack coat of polyurethane water-proof paint;
5) after step 4 terminates, with blowing agent in doors to the filling of gap, hole, formation blowing agent loading layers is fixed rainwater leakage prevention and is stretched out roofing pipe;
6) after the levelling tack coat solidification of polyurethane water-proof paint, then cover water baffle with polyurethane water-proof paint, form polyurethane water-proof paint covering layer;
7) after the solidification of polyurethane water-proof paint covering layer, cover polyurethane water-proof paint covering layer with polymer cement mortar, form polymer cement mortar topping;
8) stretch out roofing pipe to rainwater leakage prevention in doors by clip to fix.
To the improvement of above-mentioned construction method, the polyurethane water-proof paint covering layer in step 6 is that taper stretches out the accumulation of roofing tube hub place to rainwater leakage prevention.
To the further improvement of above-mentioned construction method, the thickness of the polymer cement mortar topping in step 7 is 1.5-3.5cm.
Beneficial effect of the present invention is for roof waterproof weakest link---design effectively is carried out in the connection of stretching out roofing pipe and roofing, to guarantee the leakage-proof and seepage-proof of roofing to rainwater, avoids losing within doors because rain leakage causes.Advantage is:
(1) good water-proof effect.The present invention realizes the double plane waterproof technique of Double-contact surfaces by water baffle, greatly improves the water resistance of stretching out roofing pipe periphery.
(2) easy for installation.Compare and existingly stretch out roofing pipe waterproof technique, the present invention installs and wants easy to be many.
(3) applied range.Can apply at New Buildings, also can change according to construction method when existing building roof waterproof keeps in repair and stretch out roofing pipe.
