C, waterproof roofing construction technology
First top plate basal plane is cleared up, determines installation of membrane direction, pops up reference line on top plate basal plane, between reference line
Distance is the width of a width coiled material, reserves the no less than overlapping the slot of 80mm according to the width of selected coiled material；
It is pre-configured with lean concrete grout by the weight ratio 2:1 of cement and water, lean concrete grout is scratched on top plate basal plane, scrapes element of cementing
Slurry with a thickness of 1.5~2.5mm, and the long side than coiled material to be laid, short side it is each it is wide go out 100mm, in knifing process pay attention to protect
Demonstrate,prove flatness；Returning is lifted into the 1.5mm thickness reaction bonded type wet-laying waterproof roll one end for filling lean concrete grout, and paving is in top
On plate basal plane, discharge air is scraped to both sides among coiled material with scraper plate, the lean concrete grout for scraping discharge is returned and scrapes edge sealing, coiled material
The other end carries out paving processing by same procedure to form first of waterproof roofing layer；It is completely solid to first of waterproof roofing layer
Afterwards, fissure of displacement large area does viscous paving 1.5mm thickness reaction bonded type macromolecule wet-laying waterproof roll to form second top on it
Plate waterproof layer；It is laid with protective layer in time on second waterproof roofing layer；
In construction, roof deformation seam is reserved, it is anti-to add one layer of 1000mm wide 1.5mm thickness reaction bonded type wet-laying in deformation joint
The enhancement layer of water coiled material, and round bar shape foamed plastic rod is added in centre, the two sides of enhancement layer are carried out close using waterproof sealing cream
Envelope.
2. pipe gallery Waterproof Construction Technique according to claim 1, which is characterized in that the deformation joint was added
The enhancement layer of 1.5mm thickness reaction bonded type wet-laying waterproof roll uses double-sided adhesive waterproof coiled material.
3. pipe gallery Waterproof Construction Technique according to claim 1, which is characterized in that the overlap of roll end answers phase
Mutually it is staggered not less than the 1/3 of coiled material wide cut.
4. pipe gallery Waterproof Construction Technique according to claim 1, which is characterized in that, will be adjacent in wet-laying coiled material
The isolation film of the lap-joint of coiled material is torn, and scratches paving edge fit after lean concrete grout.
5. pipe gallery Waterproof Construction Technique according to claim 1, which is characterized in that before coiled material is laid with, all inner corner trims
R50 circular arc type is done, external corner does R20 circular arc type, and the reaction bonded type for being both needed to add one layer of 500mm wide 1.5mm thickness at yin-yang angle is wet
The enhancement layer of waterproof roll is spread, the two sides of enhancement layer are sealed using waterproof sealing cream.
