Description
Technical field
The invention belongs to buildings to repair field, especially a kind of leakage of coil roofing maintenance process.
Background technique
Roof leakage maintenance is very common phenomenon, and roof leakage easily occur in especially some houses long neglected and in disrepair,
However the reason of roof leakage be it is varied, cannot treat different things as the same.
Roof leakage is mainly the following reason:
One, the defect with design is reconnoitred
Soil exploration layouts unreasonable or is limited the exploration that cannot layout according to standard by place, and foundation is caused to set
There is relatively large deviation in timing, differential settlement occurs after leading to building use, and then makes roofing Local Cracking and leak.Design
Upper building roof flat shape bumps are more, easily form stress at bumps and concentrate, at the lower formation cracking that expands with heat and contract with cold throughout the year.
Two, the influence of sunshine
Prolonged illumination can eventually lead to and accelerate the aging and fracture of waterproof roll.
Three, the influence of temperature
High temperature can accelerate the oxidation and ageing process of asphalt material.The viscosity flow of material is very big at high operating temperatures, holds
It is also easy to produce plastic creep.Low temperature can be such that the brittleness of common water-proofing coiled material increases, and cold(ing)crack and deformation is caused to be broken.This
Sample, if ambient air temperature changes greatly or when temperature is lower, fracture or the probability of cracking, which will occur, for material to obviously increase.
Four, the influence of rainfall and snowfall
More frequent and long roof ponding can cause local damage to waterproof roll.Snowfall cooling and longer thawing
Process also will increase the brittleness of common waterproof material.
Five, the influence of construction technology
Basement process is not in place, and after building up load differential settlement occurs for residential building, leads to parapet even roofing cracking
Cause to leak.Roof construction layer quality is not checked on, prestressed cored slab rainy duct internal water accumulation during installing, by one section
The load action of time, prestressed cored slab occur deflection deformation, cause plate end crack, ponding exudation, cause bedroom cross wall with
Ceiling intersection leaks.Roofing screed-coat is with low quality, without sufficiently dry, dusting；Substrate surface is uneven etc.；Or
Person's waterproof roll itself it is off quality；Or since hot glue ramming material and self-adhering-type coiled material construction temperature are low, cause waterproof layer
It is bonded loosely with base and removes disengagement and form waterproof layer and binder course removing.Roof-base is uneven or base does not clean
Completely, to there is the dusts such as miscellaneous soil to be mixed into form separation layer；Screed-coat intensity is low, of poor quality；Roofing area is bigger, parting seam
It is arranged unreasonable；Adhesive bitument primer covers difference etc..Rolled roofing material overlapping mode is nonstandard, and inlet for stom water, coiled material are received at first-class thin portion
It manages not in place.
Six, the influence of roof construction design
In the biggish situation of the building roof ratio of slope, rainwater can be smoothly discharged out roofing, reduce rainwater and pitch is anti-
The time of contact of water coiled material, so as to extend the service life of waterproof material.
Seven, the influence of roof use process
In normal use, asphalt water-proof coiled material is caused to be destroyed due to maintenance roofing or in roofing setting other equipment.
In accessible roof maintenance, in the case where not paying attention to protection, pitch is easy to be trampled on.Other equipment are when being installed on roofing
Fixation may destroy common waterproof roll.Such as television antenna, solar water heater are installed.
Will receive various factors in prepared roofing use process, the influence including design, construction, material, environment etc. and send out
It is raw to destroy and leak.In the prior art, foot pain of usually treating the head when the head aches cures foot and takes an unnecessary way, without comprehensively dividing before maintenance
Analysis, the leakage for caused by different reasons are all made of single method to handle, and causing repeatedly to repair but not can solve at all
Problem.
Summary of the invention
Since above-mentioned deficiency exists in the prior art, the present invention provides a kind of leakage of coil roofing maintenance process.This hair
The bright different damaged situation for prepared roofing has pointedly used different renovation techniques.And developing one kind has
