Description
Technical field
The present invention relates to a kind of waterproof and heat-insulating roof and job practices thereof.
Background technology
Existing roof with waterproof and heat-insulating function normally is provided with insulating and waterproofing course on common deck deck.Insulating is made by perlite concrete, haydite concrete, gas concrete or hard polyurethane foam usually.And waterproofing course has waterproof concrete, waterproof mortar plaster of rigidity etc.; Flexible have asphalt felt, high-polymer modified pitch felt and synthetic high polymer coiled material, high-polymer modified pitch coating, a synthetic high polymer coating etc.; Toughness cement-base waterproof coating arranged.All there is different shortcomings in these waterproofing courses; Rigid waterproof layer because self density is limited, a little less than the commensurate structure deformability, split leak and the seepage phenomenon very general; The cement-base waterproof coating of toughness and flexible waterproof roll or water-repellent paint are chemical material basically, expose to the open air under the environment of the Nature very easily agingly, lose and adapt to deformation ability and water-proof function, and its waterproof durable time limit only be some months extremely several years.Below be a kind of structure and job practices of common waterproof and heat-insulating roof:
A. the reinforced concrete structure layer with common deck washes, and the brushing cement paste forms setting course then;
B. smear the cement mortar that is added with an amount of waterproof agent, form leveling layer;
C. paving waterproof roll or brushing water-repellent paint form flexible waterproof layer;
D. smear cement mortar or build pea gravel concrete, form topping;
E. cast-in-place light expanded perlite concrete or haydite concrete etc. form insulating;
F. cast-in-place steel mesh pea gravel concreten is established the lattice seam, with the waterproofing unction filleting, forms the rigid waterproofing topping;
G. use cement mortar press polish or paste block material, form surface layer.
Wherein the effect of setting course is atomic, if the reinforced concrete structure laminar surface is clean or drying or ponding all can be ineffective, even becomes reactive " separation layer "; Leveling layer is uneven or too coarse and be provided with in order to overcome the reinforced concrete structure layer traditionally, but it not only is difficult to play waterproof action, also brings hollowing and common quality defects such as cracking, dusting unavoidably; The key of flexible waterproof layer is selection and construction technology, select low-grade pitch class coiled material or coating for use, though cost is low, but poor durability, easily aging, contaminated environment, select middle-grade modified bitumen class coiled material or coating for use, cost is moderate, but the construction requirement height, quality is difficult for guaranteeing, still have the polluter in the majority to environment, resistance to ag(e)ing is not high yet, selects high-grade synthetic high polymer class coiled material or coating for use, though ageing-resistant performance is higher, also than environmental protection, but the cost height, the construction requirement height also is difficult for guaranteeing waterproof effect, so existing waterproofing course all belongs to chemical material, has problem of aging, problem of environmental pollution, construction quality is difficult to problems such as assurance; The effect of topping is to prevent that flexible waterproof layer from causing damage because of follow-up construction, and also there is the common fault of hollowing, cracking and water storage unavoidably in it; Existing insulating has good heat insulation and preservation effect, but cost is higher, and difficulty of construction is also big relatively, and water content is big and be difficult to drainage, after being covered by surface layer, at the surface layer and the waterproofing course that can destroy under the influence of temperature frequent variations on it; The rigid waterproofing topping is the topping of insulating; The effect of surface layer is for attractive in appearance, solid, but common quality defects such as its hollowing, cracking are difficult to avoid equally.
Summary of the invention
The objective of the invention is that a kind of cost of production is low in order to provide, the waterproof and heat-insulating roof and the job practices thereof of environmental protection, long service life.
Main technical schemes of the present invention is: flexible waterproof layer and polymer cement coating that this waterproof and heat-insulating roof is the isolated protective layer made at the insulating that adopted magma machinery to polish to be disposed with between the rigid waterproofing surface layer of technology and the common deck deck separation layer be made up of plastic woven cloth from top to bottom, made by steam-pressing aero-concrete, by permeable type nonwoven, made by sodium bentonite.Its job practices is:
A. when the roof structure concreting, adopt magma machinery to polish operation, form common deck deck with rigid waterproofing performance;
B. be coated with by acrylic acid ester emulsion on common deck deck upper berth and mix high quality silicon acid salt cement and quartz powder coating, form polymer cement coating with toughness water resistance;
C. do the shop sodium bentonite then, form flexible waterproof layer;
D. do the permeable type nonwoven in shop, form isolated protective layer;
E. do shop steam-pressing aero-concrete prefabricated section, form insulating;
F. do the shop plastic woven cloth, form separation layer;
G. last cast-in-place steel mesh pea gravel concreten adopts magma machinery to polish, and can directly become
H. be the rigid waterproofing surface layer.
In the present invention's construction, when the roof structure concreting, adopt magma machinery to polish operation, make common deck deck become the rigid waterproof layer of high-efficiency and economic, and can cancel setting course, the leveling layer that brings many quality problems; The good and cheap and environmental protection of polymer cement coating with toughness water resistance; Do flexible waterproof layer that the shop sodium bentonite forms have excellent water resistance and never wear out, characteristics such as easy construction, cost are low, absolute environmental protection; The isolated protective layer of doing the permeable type nonwoven formation in shop is economical and practical; The insulating of doing shop steam-pressing aero-concrete prefabricated section formation has reduced common quality defect under the prerequisite that keeps effect, improved efficiency of construction, has reduced cost; The separation layer of doing shop plastic woven cloth formation is economical and practical equally; The rigid waterproofing surface layer is cast-in-place steel mesh pea gravel concreten, adopts magma machinery to polish, and not only can directly make surface layer but also be practical rigid waterproof layer, has cancelled the cement mortar surface layer of easy hollowing, cracking simultaneously, reaches the purpose of labor and material saving.
