Description
Technical field
The utility model is related to the exterior wall stringcourse eliminator plates and its construction method of a kind of rainwater leakage prevention, and in particular to a kind of
For the frame board and its construction method of the rainwater leakage prevention of skin stringcourse；Belong to architectural engineering external wall waterproof technology neck
Domain.
Background technology
Skin is also easy to produce Seepage because being directly exposed under rainwash, and exterior wall stringcourse position because than
Common exterior wall has had more cross section, causes to splash on rainwater, which easily generates infiltration phenomenon, and indoor wall is caused to make moist, wall
Skin is mouldy the influences such as to come off.For this purpose, would generally External Wall stringcourse position do water-proofing treatment, but in application practice, common waterproof
The infiltration phenomenon at the position can not be fully solved, in engineering construction, exterior wall stringcourse position often becomes the collection of exterior wall leakage
Middle position.
At present, the processing method for exterior wall stringcourse position waterproof hidden danger phenomenon is often added polyurethane at the position and is prevented
The method of water layer, this method have problems in that：(1) stringcourse upper wall body and stringcourse horizontal position waterproofing process and floating
Layer, insulating layer, protective layer and surface layer are typically separately done, this allows for the presence of perforation seam between vertical way and horizontal way；(2)
When wall by temperature stress, drying shrinkage, differential settlement when influencing, it is easier that there are micro-cracks in waterproof layer；(3) rushed by rainwater
Brush, exterior wall stringcourse position causes to splash on rainwater, stringcourse position exterior wall paint can generate brokenly because having had more cross section than common exterior wall
Damage without water-proof function, and causes rainwater to go deep into protective layer, keeps the temperature in flaggy, penetrates into wall along waterproof layer crack, thus outer
Wall stringcourse position often becomes the concentration position of exterior wall leakage.And after there is leakage, repair method is typically to be brushed again in wall face
Polyurethane water-proof paint or with SBS modified pitch, but both unsightly, and influenced by solarization aging, it can only solve to ask in a short time
Topic, it is impossible to fundamentally prevent exterior wall stringcourse rain leakage problem.
The content of the invention
Technical problem to be solved in the utility model is：It is oozed for most scabrous stringcourse position rainwater in external wall waterproof
The technical issues of leakage.
The design philosophy of the utility model is to pass through exterior wall stringcourse eliminator plate base plate protection stringcourse top surface layer so that rain
Water is not directly fallen on stringcourse；The wall face on stringcourse top is protected by exterior wall stringcourse eliminator plate side plate so that the rainwater splash
The side plate to stringcourse eliminator plate is broken, no longer washes away wall face, has completely cut off rainwater and has been connect with originally hidden leakage defect point that may be present
It touches, so that it is guaranteed that exterior wall stringcourse position waterproof quality.
The purpose of this utility model is that for external wall waterproof weakest link --- exterior wall stringcourse position exterior wall and waist
Line connection carries out design effectively, to ensure antiseep of the exterior wall to rainwater, avoids losing within doors caused by rain leakage.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
The exterior wall stringcourse eliminator plate of a kind of rainwater leakage prevention, including bottom plate and the resistance that is connected with the edge for the bottom plate that blocks water of blocking water
Water side plate blocks water and an angle for being more than 90 ° is formed between bottom plate and the side plate that blocks water, and block water bottom plate and the side plate that blocks water constitute one
A exterior wall stringcourse eliminator plate with angle；Evagination sets two boss and two boss difference positions in the plate face for the bottom plate that blocks water
In the both ends for the bottom plate plate face that blocks water；Threaded hole is respectively provided in the centre of two boss and two threaded holes are through the bottom that blocks water
Plate；Adjusting screw is inserted into two threaded holes.
The utility model is for external wall waterproof weakest link --- the junction of stringcourse and exterior wall is analyzed
Research, devises a kind of exterior wall stringcourse eliminator plate for rainwater leakage prevention.The technical solution main contents are：Pass through exterior wall waist
Line eliminator plate base plate protection stringcourse top surface layer so that rainwater is not directly fallen on stringcourse；Pass through exterior wall stringcourse eliminator plate side plate
Protect the wall face on stringcourse top so that the rainwater splash breaks the side plate to stringcourse eliminator plate, no longer washes away wall face, isolation
Rainwater contact with original hidden leakage defect point that may be present, so that it is guaranteed that exterior wall stringcourse position waterproof quality.
Exterior wall stringcourse eliminator plate, boss in technical solutions of the utility model is using solar control aging, the material of corrosion resistant
As aluminium sheet is made.
The angle to block water between bottom plate and the side plate that blocks water design in technical solutions of the utility model, according to stringcourse during construction
The gradient of slope, when processing exterior wall stringcourse eliminator plate, the side plate that blocks water, slightly larger than 90 degree, is hindered with the angle for the bottom plate that blocks water so as to reduce
