[detailed description of the invention]
(1) professional waterproof Deepen Design
(1) emphasis of professional waterproof Deepen Design:
According to building and structure design, in conjunction with field condition, professional waterproof Deepen Design is carried out, mainly to the structure gradient to roof water-proof, the gutter gradient, drain hole, spillway hole, structural joint, give prominence to roof structure, equipment, pipeline etc., flange designs, fix, carry out checking computations and detail node design.Under ensureing limiting case, draining is unobstructed, and outfall does not block, and quality of waterproof layer is intact.Simultaneously to setting and the requirement of topping, shrinkage joint, settlement joint etc. stay connection details such as establishing position, anti-limit, corner, build-in to carry out secondary detailingi etc., really reach roof and do not stay water, do not seep water.
The design of the structure, the gradient, major groove, draining, overflow, anti-limit, corner, build-in etc. on each roof is not identical, and secondary detailingi just effectively can not ensure that roof drainage is smooth and easy, not ponding targetedly, and waterproofing course firmly, reliably.Just can not ensure that roof is non-leakage.Just can not ensure roof not ponding, non-leakage in waterproofing materials design period of validity.
(2) concrete measure of secondary detailingi:
1, roofing not ponding is ensured: the structure gradient on roof, the gradient in gutter, the size in gutter, the layout of drain hole and size, the layout of spillway hole etc. effectively can ensure roof not ponding.
2, waterproofing course is non-leakage: waterproofing course forms integral layer, and basic unit combines closely, has enough elasticity and toughness, durability.
3, topping is protected waterproofing course in time, and itself is also one waterproofing course, guarantees that waterproofing course is not damaged by construction, takes root in damage.
4, the Deepen Design of thin portion, node: structural joint, the structure of outstanding roofing, equipment, pipeline place, corner, anti-limit place, the design of node of reversed beam, post and masonry interface etc.
5, professional structure manufacture: the casting die on anti-limit, wears the clip of roof pipeline, the structure of outstanding aspect, the fixture on the anti-limit of equipment, necessary specialized designs, the making such as protective cap that prevent inlet for stom water from block.
6, use management measure: routine use sets up inspection system, a roof of monthly patrolling, roof of patrolling before and after heavy rain, Timeliness coverage problem, prevents roof ponding.
(2) waterproofing materials
Roof flashing material refers to the material that can effectively prevent moisture, steam etc. in rainwater and air from invading building.Desirable waterproofing materials effectively inside concrete steam can be volatilized; can be impervious and tolerate strong hydraulic pressure for a long time; energy and concrete base layer combine closely; overall without interface; life-span same with concrete; the protection such as root thorn concrete structure can be effectively prevented to have lasting water-proof function and better compactness and compressive strength, easy construction.Domestic at present also do not have this material.
Reach this waterproof effect, the waterproof composite material of (from wound) pure interior emulsion water-proof layer+pure-acrylic emulsion water-repellent paint topping should be adopted, be i.e. the waterproofing course of different proportion preparation and topping (waterproofing course+topping composite water-proof).
(1) this waterproof composite material characteristic and advantage:
1, strong with base material adhesion stress, without interface.
2, can be impervious and tolerate strong hydraulic pressure for a long time, there is not problem of aging, combine closely the same life-span with concrete, that is there is " forever " water proofing property.
3, the globality of energy available protecting waterproofing course, and top construction damage.
4, require low to construction environment, do not have open fire to construct.
5, speed of application is fast, and intensity is high, saves the duration.
(3) integrated construction management
Construction quality is the decision link determining end product quality.Must pay much attention to and scientific management.Conscientiously tell somebody what one's real intentions are system, operation handing-over system, on-the-spot other station system, system of accountability in the scene of implementing, and strict control stress point, difficult point and thin portion structure, ensure construction quality.
(1) construction quality priority control point:
1, base cleaning: base cleaning is the necessary preparation before construction, base cleaning can ensure that roof basic unit finds roof structure layer defects without sharp object, carries out repairing or rectify and improve before waterproof construction.
2, construct: job instruction construction strictly pressed by waterproofing materials, first local test, qualified large-area construction again.The first bottoming process of the waterproof weak location such as corner, structure lap position, scupper; then planned sequence of construction carries out construction of waterproof layer; carry out fish tail and waterproof layer construction in time after passed examination, the anti-limit of the construction 20mm lower than waterproofing course of topping, and the professional component of timely self-control is fixed.
