Description
Technical field
The utility model relates to a kind of waterproofing and thermal insulation of roofing system of roof planting greening.
Background technology
Because the building function requirement of green roof, the vegetation of most of roof planting all has very strong energy for growth, can adapt to any environment.As long as some spaces are arranged, they will constantly be grown, even penetrate cement board or general waterproofing course.In case waterproofing course is penetrated, rainwater will enter building up to destroying the building protection layer.Vegetation root system can penetrate separation layer then, slowly destroys whole building system.Anti-root system of plant puncture ability of existing green roof waterproofing system and obstruct steam performance are poor, can't satisfy the green roof waterproof requirement.
Summary of the invention
The utility model is that a kind of green roof waterproofing system will be provided, and the anti-root system of plant puncture of this system ability is strong, and the obstruct steam performance is good, and it is convenient to construct.
For achieving the above object, the technical solution of the utility model is: a kind of green roof waterproofing system, comprise insulation layer, be layed in the roofing bottom waterproofing course above the insulation layer, be characterized in: comprise that also steam stops layer, root resistance waterproofing course is equipped with steam and stops layer on the roof-base face, be equipped with root resistance waterproofing course above the roofing bottom waterproofing course.
Be equipped with cement mortar protective course successively, retaining drainage blanket, filtration beds above the root resistance waterproofing course; The bottom waterproofing layer thickness is 3-4mm, maximum vertical, horizontal stretching resistance 450-1000N/50mm; It is 1.2-4mm that steam stops layer thickness, maximum vertically stretching resistance 400-950N/5cm, maximum transversal stretching resistance 300-950N/5cm; Root resistance waterproofing layer thickness is 2-4mm, maximum vertical, horizontal stretching resistance 800-1100N/50mm.
The beneficial effects of the utility model are:
1. ageing resistace is strong
Coiled material that waterproofing system of the present utility model adopts is the SBS modified bituminous pitch coiled material, and the high-quality characteristic of modified product not only depends on the raw material of product, but also depends on their hybrid mode and the associated methods between the mixture different aspects.In order to make waterproof roll have the high-quality characteristic of modified bitumen, the additive of an amount of ratio and special addition manner must be arranged.Pitch just can be resisted variation of temperature and have very strong ageing resistace like this.This system uses the coiled material durable years can reach 25 years, the exterior components that is used to build, and its durability is enough to satisfy the requirement of 15 years service lives of II level waterproofing.
2. tensile property is strong
The stretching resistance of coiled material and elongation per unit length be by the decision of the quality of tire base, the profile and the mechanical performance of tire base decision coiled material.The glass fiber blank base can be strict maintenance appearance and size, but itself is not strong to the relative displacement compliance of basic unit, when serious even can rupture.And poly-ammonia tire base can adapt to relatively moving of basic unit owing to have certain pliability, and it can adapt to stretching extremely and have good elongation per unit length.Such as in the poly-ammonia tire base of elasticity, adding stable spacing reinforcing of glass.The advantage of this way is that the elasticity and the high-intensity characteristic of glass fiber of poly-ammonia tire base combine, thereby reaches desirable effect.
3. anti-root system of plant puncture ability is strong
Because the building function requirement of green roof, the vegetation of most of roof planting all has very strong energy for growth, can adapt to any environment.As long as some spaces are arranged, they will constantly be grown, even penetrate cement board or general waterproofing course.In case waterproofing course is penetrated, rainwater will enter building up to destroying the building protection layer.Vegetation root system can penetrate separation layer then, slowly destroys whole building system.Therefore, in the waterproofing system according to the development degree of plantation vegetation root system, can corresponding employing polyester blank base, the coiled material of the compound tire base of copper polyester and the compound tire base of glass.Just can rebound when root system of plant touches the tire base, contain the environment friendly biological additive in the modified bitumen coating simultaneously, root system of plant also can be rebounded owing to the effect of environment friendly biological additive at the overlap edge place.By as above duplicate protection, make coiled material in the planted roof system, bring into play powerful root-resistant puncturing performance, plant there is not any adverse effect.
4. it is good to intercept steam performance
For stoping the water vapour in the building to enter insulation layer, cause heat-insulating property to descend by the roof structure plate; And stop existence because of water recovery water, and cause root system of plant to break through the inducement of waterproofing course to the insulation layer puncture.Waterproofing system has designed steam and has stopped layer under insulation layer, comprise the compound tire base of compound tire base of netted aluminium foil polyester (self-adhesion) and aluminium foil glass (hot melt), selects for use according to the different structure basal plane.Intercept by steam, thereby the roof heat insulation performance is guaranteed all the time in optimum state.
5. it is convenient to construct
Waterproofing system of the present utility model construction rapidly, (on-the-spot paving (self-adhesion or hot melt) is adopted in the specification encapsulation of 1m * 10m) to coiled material, and the construction period is shortened greatly with the 10m2/ volume.Go for the roof-base of different shape, material simultaneously, and reduced the node processing on traditional roofing, from the textural possibility that produces seepage that reduced.
Description of drawings
Fig. 1 is a structure scheme of installation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, green roof waterproofing system of the present utility model comprises insulation layer 3, is layed in the roofing bottom waterproofing course 4 above the insulation layer 3, and steam stops layer 2, root resistance waterproofing course 5, cement mortar protective course 6, retaining drainage blanket 7, filtration beds 8.
Be equipped with steam on 1 of the roof-base and stop layer 2, be equipped with root resistance waterproofing course 5 above the roofing bottom waterproofing course 4.Be equipped with cement mortar protective course 6 successively, retaining drainage blanket 7, filtration beds 8 above the root resistance waterproofing course 5.Place nutrition soil 9 and plant above the filtration beds 8.
Construction technology process of the present utility model:
Clear up basic unit → brushing base treatment agent → paving steam obstruction layer coiled material (hot melt) → laying insulation layer, edge joint position employing adhesive tape secure bond → laying bottom waterproof roll (self-adhesion or the hot melt) → laying top layer root resistance waterproofing course coiled material → water pouring test → whole examination → cement mortar protective course construction → afforested areas division of rolled roofing material laying water storage and drainage plate → cover nutrition soil → vegetation to plant.
