Abstract
A construction technology of bituminous waterproof sheet materials comprises the steps that firstly, a foundation layer is cleared up; secondly, the foundation layer is fully painted with a chloroprene rubber bitumen binding agent diluted in gasoline; thirdly, additional layers are made for the corners, and construction is carried out through modified bituminous sheet materials in a hot melting mode; fourthly, modified bituminous waterproof sheet materials are cut to be of corresponding sizes, and are rolled for use, the junctions of the foundation layer and the sheet materials are evenly heated through a flame gun in a reciprocating mode, the sheet materials are rolled and laid forwards and are pasted to the foundation layer when bitumen just melts, and the lap joint portions are tightly pasted in a hot melting mode according to a full adhesion method; fifthly, the lap joint seams of the sheet materials are heated through the flame gun, so that the sheet materials are firmly pasted until bitumen is extruded out of the edges, and shrinking heads at the tail ends are tightly caulked with sealant; sixthly, a protective layer is constructed. The construction technology of the bituminous waterproof sheet materials is simple in laying process and good in laying effect, and every layer is smooth and seamless.
Description
Technical field
The present invention relates to building materials and prefabricated house field, particularly a kind of asphalt water-proof coiled material construction technology.
Background technology
Asphalt water-proof coiled material refers to carcass material dip-coating pitches such as body paper, fibrofelt, and surperficial spreading powdery, granular or flaky material are made sheet waterproofing materials that can be curling, include tire coiled material and Padless coiled material, have tire coiled material to comprise oilpaper and malthoid.
In existing asphalt water-proof coiled material work progress, often there is being difficult to lay problem smooth and that stickup is tight.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of asphalt water-proof coiled material construction technology.
To achieve these goals, the technical solution used in the present invention is:
A kind of asphalt water-proof coiled material construction technology, comprises the steps:
The first step, cleaning basic unit is clean by base cleaning;
Second step, brushing base treatment agent: completely brush the neoprene pitch binder with gasoline dilution together in basic unit;
The 3rd step, extra play construction, does extra play at position, turning, uses modified bituminous pitch coiled material hot melt application;
The 4th step, hot melt paving coiled material, is cut into corresponding size by modified asphalt waterproof coiled material, spools for subsequent use, with flame gun homogeneous heating basic unit and coiled material intersection, heating in reciprocating mode, in the time that pitch just melts, coiled material is rolled forward to paving, affix in basic unit, overlapping part cements by completely sticky method hot melt;
The 5th step, hot melt edge sealing, by the heating of coiled material lapping seam place, makes the two bonding firmly with spray gun, extrudes pitch as qualified take edge, and it is tight that end is received head sealing compound pointing;
The 6th step, topping construction, accessible roof topping does rigid roofing by designing requirement, and accessible roof does not have following processing as topping: a. waterproofing course external coating neoprene pitch binder, then spread flag topping; B. waterproofing course external coating silvery reflection coating.
Compared with prior art, process of deployment is simple in the present invention, laying effective, and each layer is smooth seamless.
The specific embodiment
Below in conjunction with embodiment, the present invention is carried out to more detailed explanation.
The present invention is a kind of asphalt water-proof coiled material construction technology, comprises the steps:
The first step, cleaning basic unit is clean by base cleaning;
Second step, brushing base treatment agent: completely brush the neoprene pitch binder with gasoline dilution together in basic unit;
The 3rd step, extra play construction, does extra play at position, turning, uses modified bituminous pitch coiled material hot melt application;
The 4th step, hot melt paving coiled material, is cut into corresponding size by modified asphalt waterproof coiled material, spools for subsequent use, with flame gun homogeneous heating basic unit and coiled material intersection, heating in reciprocating mode, in the time that pitch just melts, coiled material is rolled forward to paving, affix in basic unit, overlapping part cements by completely sticky method hot melt;
The 5th step, hot melt edge sealing, by the heating of coiled material lapping seam place, makes the two bonding firmly with spray gun, extrudes pitch as qualified take edge, and it is tight that end is received head sealing compound pointing;
The 6th step, topping construction, accessible roof topping does rigid roofing by designing requirement, and accessible roof does not have following processing as topping: a. waterproofing course external coating neoprene pitch binder, then spread flag topping; B. waterproofing course external coating silvery reflection coating.
In process, in the time running into cornice, eaves gutter paving coiled material falls mouth to dividing ridge gradient direction paving downstream from bottom of trench, and Bian Pu limit scrapes to both sides with scraper plate, drives bubble out of, makes installation of membrane smooth, pastes closely knit.
Paving is cut out after neat and is pressed in groove to the coiled material of cornice termination, and then that groove is closely knit with caulked joint ointment pointing, groove stays to be established unified bracing wire and looks for directly, accomplish attractive in appearance unanimously.Because eaves gutter position water flow is larger, waterproofing course is often subject to rain drop erosion or immersion, is therefore first coated with envelope with caulked joint ointment in eaves gutter corner, and every hem width degree is not less than 30mm, after being dried, sets up one coiled material as extra play again.
In the time running into water and fall cup, before rolled roofing material is laid, first the water mouth that falls is carried out to encapsulation process.Fall cup while burying underground at water, and the fall junction of cup and vertical tube bell and spigot of water is just closely knit with caulked joint ointment pointing, prevents that this position from producing pouring phenomenon in the time of heavy rain.Water does extra play with waterproof coating in falling mouthful around diameter 500mm, and thickness is not less than 2mm, and wide 20mm, the groove of 20mm deeply, pointing caulked joint ointment are stayed in fall cup and basic unit contact position of water.Spread the each layer coiled material and the extra play that fall mouthful to water, must stick on rim of a cup, clamped with the chassis of rainwater cover, between chassis and coiled material, full coat ointment is bondd, and envelope is filled out with encapsulant around in chassis.
In the time running into exhaust hole and stretch out roof pipeline, exhaust hole is similar to roofing corner with wall to the laying method of roofing angle of cut place coiled material, difference is that current direction must not have unfavourable balance, and inner corner trim place, exhaust hole coiled material increases extra play one, and top clip intersects sturdy.
Stretching out roof pipeline installation of membrane need increase two-layer extra play, and after waterproofing course paving, tighten with iron wire upper end, finally seals with sealant.
In the time running into negative and positive angle, by after basic unit's gluing at negative and positive angle place, the every limit 100mm of elongation is coated with envelope sealing cement, repaves a layer coiled material extra play, cuts the sealing compound sealing of seam place after paving.
