Abstract
The invention relates to a composite waterproof layer and a construction method thereof, belonging to the technical field of construction process waterproofing work. The construction method comprises the following steps of: firstly coating a rigid waterproof coating on the surface of a basement layer; under the condition that the rigid waterproof coating is wet and uncured, covering a reinforcing rib layer on the surface of the rigid waterproof coating; and finally coating an elastic waterproof coating on the surface of the reinforcing rib layer under the condition that the rigid waterproof coating is wet and uncured, thus complete sealing is realized. The invention has the beneficial effects that the composite waterproof layer formed by adopting the construction method provided by the invention has high evenness, no lap joint, low requirement to the surface of the basement layer and good integral waterproofness, and no water channelling is caused.
Description
Technical field
The invention belongs to architectural process waterproofing work technical field, relate in particular to the job practices of a kind of complex waterproof layer and complex waterproof layer.
Background technology
In building field, for anti-sealing to the infiltration at some position of building from the constructional materials with the textural waterproof measure of taking.At present, the measure that people generally take is on basic unit's table, to apply water-repellent paint or waterproof roll, and the coiled material advantage is that thickness is even; Bed thickness is grasped by the requirement of setting up defences easily, calculates accurately with material, and shortcoming is in work progress, to need to cut the garment according to the figure according to the shape of waterproof matrix; Basic unit for complex contour needs the polylith splicing; The bonding difficulty of lap-joint is bigger each other, is difficult to complete positive confinement, and the hidden danger of leaking is big.No matter the bonding of waterproof roll and basic unit is Man Pu, Dian Pu, bar shop, empty shop, all very easily becomes between coiled material and the basic unit and scurries water layer, in case there is penetrability damaged, comes unstuck, leaks glue, and the water-proof function of whole waterproofing course is all with total loss, and maintenance is difficulty very.
The advantage of water-repellent paint is that easy construction is simple, and there is not overlap joint in waterproofing course, the zone that coiled material can't be constructed; Particularly complicated position, coating all can perfectly solve, and water tight integrity is good; But shortcoming is that the planeness of basal plane is had relatively high expectations; Receive the uneven influence of basal plane, became uneven easily, thickness are the coating pass decisions during according to construction.
Summary of the invention
Said defective above the objective of the invention is to be directed against, provide a kind of and need not to overlap, water tight integrity is good, thickness evenly, can not form the complex waterproof layer of scurrying water layer and hard and soft combination.
Another object of the present invention provides a kind of job practices of complex waterproof layer.
The objective of the invention is to be achieved through following technical scheme.
A kind of complex waterproof layer is characterized in that, is made up of rigid waterproofing coating, reinforcing rib layer and elastic water-proof coating, and the reinforcing rib layer is between rigid waterproofing coating and elastic water-proof coating, and the rigid waterproofing coating is overlying on substrate surface.
A kind of job practices of complex waterproof layer is characterized in that, may further comprise the steps successively: 1. apply the rigid waterproofing coating in substrate surface, substrate surface is carried out smooth processing; 2. be under the moistening not dried state in the rigid waterproofing coating, cover the reinforcing rib layer, make the reinforcing rib layer be close to and soak at the rigid waterproofing coating surface at the rigid waterproofing coating surface; 3. be under the moistening not dried state in the rigid waterproofing coating, apply the elastic water-proof coating, seal fully at the reinforcing rib laminar surface.
Said rigid waterproof layer can adopt a kind of in osmosis type rigid waterproofing coating, non-osmosis type rigid waterproofing coating, cement mortar or the rubber cement.The thickness of said rigid waterproofing coating is 0.8mm～30mm.
Said reinforcing rib layer adopts nonwoven or glass cloth.
All there is fiber on said nonwoven two sides, and the fiber on nonwoven two sides infiltrates through respectively in rigid waterproofing coating and the elastic water-proof coating during construction.
The thickness of said elastic water-proof coating is 0.5mm～3.0mm.
The invention has the beneficial effects as follows: the complex waterproof layer that adopts job practices according to the invention to form, planeness is high, does not have overlap joint, and low to the substrate surface requirement, the integral waterproofing performance is good, can not scurry water.Elastic water-proof coating according to the invention just seals rigid waterproof layer when the rigid waterproofing coating is in moisture state fully; The rigid waterproofing coating is under the optimum state of not dehydration or few dehydration always, and osmosis type rigid waterproofing coating more can be soaked into substrate surface fully, sealing basic unit clinking hole; Play the effect of the mending-leakage reinforcement that blocks water; Even the complex waterproof layer part is destroyed, also can water be locked in the very little scope, improved the reliability of complex waterproof layer.The fiber on non-weaving cloth two sides penetrates into respectively in rigid waterproofing coating and the elastic water-proof coating, makes whole complex waterproof layer constitute one, effectively improves the tensile strength and the endurance life of complex waterproof layer, has the reinforcement of reinforcement, cracking resistance effect.The present invention combines rigid waterproofing coating and elastic water-proof coating; The function that has two kinds of waterproof coatings simultaneously; In case base course crack; Elastic water-proof coating and reinforcing rib layer can effectively prevent the rigid waterproofing coating cracking, also can not cause the cracking of whole complex waterproof layer because of base course crack, have improved whole waterproofing course application life; The elastic water-proof coating is constructed at the reinforcing rib laminar surface, has avoided because of the coarse influence to waterproofing layer thickness of substrate surface.The present invention adopts the material safety and environmental protection, and method therefor need not to buy and store a large amount of volatile solvent (xylenes, gasoline etc.), need not fire operation in the construction, has eliminated various environmental pollution factorses and hidden fire-fighting danger, economizes on resources.
