Description
Technical field
The utility model relates to a kind of architectural structure system, relates to a kind of heat-insulation waterproof roof particularly.
Background technology
Generally include roofing surface layer in traditional roof structure, load-carrying members layer, insulation layer (doubling as sloping layer) (mostly be porous discrete material; as expanded perlite, vermiculite, slag etc.), waterproofing course (as glass fabric, non-woven fabrics, reclaimed rubber coiled material, synthetic rubber coiled material etc., or mortar or concrete etc.) and topping etc.Such roof structure also exists the defects such as waterproofing course easily destroys, insulation layer insulating efficiency is low, roofing load large, overall structure easy damaged, and urgently the roof of development of new is to solve the problem.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of novel heat-insulation waterproof roof, has excellent waterproof, heat-insulating property, has again that roofing load is little, the not advantage such as easy damaged concurrently simultaneously.
For achieving the above object, the utility model adopts following technical scheme:
A kind of heat-insulation waterproof roof; described roof comprises basic unit's (also claiming deck), complete water base hard polyurathamc insulation water-proof layer and haydite concrete topping from bottom to top successively, and described complete water base hard polyurathamc insulation water-proof layer passes through spraying method direct forming in described basic unit.
In the utility model, described haydite concrete topping also comprises an exterior trim surface layer outward.
Described complete water base hard polyurathamc insulation water-proof layer, direct spraying to form in basic unit and fits tightly with it, without the need to being prefabricated into special shape, also without the need to being realized by adhesive and the fitting tightly of basic unit, be suitable for the convenience that roof working site operation installs streamlined operation.
In the utility model, the thickness of described complete water base hard polyurathamc insulation water-proof layer depends on construction requirement, specifically can be 4-6cm, is preferably about 5cm.
In the utility model, the thickness of described haydite concrete topping depends on construction requirement, specifically can be 2-4cm, is preferably about 3cm.
The important technological parameters of described complete water base hard polyurathamc insulation water-proof layer comprises: density of material 55kg/m
3thickness 4-6 (preferably 5) cm, elongation at break and drawing coefficient are respectively 16.44%, 40.4kPa (GB/T 6344), water absorption rate 3vol% (GB/T 8810), hydrophobic rate 99.6% (GB/T10299-1988), coefficient of thermal conductivity 0.04W/ (mK) (GB/T 10291-1988), total carbon content TVOC 333.1 μ gC/g (VDA277), fire-protection rating core B1, B2 level, composite A-grade.
Described complete water base hard polyurathamc thermal-insulating waterproof material is the complete water base hard blown polyurethane materials of richness god adopting Fu Shen company to rely on North America and the exploitation of European high performance polymer material application technical research center research and development strength.Specifically, it is stoste based on polyethers, polyester, take amine as catalyzer, with water-soluble silicon-carbon type silicone oil (abbreviation organosilicon) for foam stabilizer, being blowing agent with deionized water, take phosphorus-containing compound as the macromolecular compound that the polyether polyols raw polyol that is mixed to form of fire retardant and isocyanates carry out exothermic reaction generation.This material is complete water base foaming system, this make shaping after macromolecular material hydrophilic group distribute more balanced in the material with hydrophobic group; In addition, this material is hole-closing structure, thermal-insulating waterproof superior performance, without Small molecular noxious gas emission, and strong mechanical property, durable in use, with the building same life-span.
Remarkable result of the present utility model is:
Roof of the present utility model has excellent waterproof, heat-insulating property, has again that roofing load is little, the not advantage such as easy damaged concurrently simultaneously.The anti-flammability on described roof can reach B2 rank, coefficient of thermal conductivity lower than 0.024W/ (mK), tensile bond strength is more than or equal to 0.10MPa, compressive strength is more than or equal to 0.15MPa, water absorption rate is less than or equal to 3%, dimensional stability be less than or equal to 1.5% and oxygen index (OI) be more than or equal to 26%, visible, having excellent anti-flammability, heat insulating ability, mechanical performance, water proofing property and stability etc. concurrently, is the extremely strong roof of a practicality.
Compared with conventional roof, roof of the present utility model is thermal-insulating waterproof integral structure, and basic unit wherein and complete water base hard polyurathamc insulation water-proof layer fit tightly, and without the need to by adhesive, realizes thermal-insulating waterproof heat insulating function very well; Secondly, the compound structure light weight of basic unit and complete water base hard polyurathamc insulation water-proof layer, can effectively reduce roof-shaped varying stress load, strengthens overall structure toughness and cracking resistance sex change.
With Conventional insulation as compared with extruded sheet, polyphenyl plate, mineral wool, vitrification micropearl morttar etc., complete water base hard polyurathamc heat insulating material coefficient of thermal conductivity of the present utility model is little, high insulating effect; and; bonding force is strong, thermal-insulating waterproof one, low-carbon (LC), green, environmental protection.
The mechanical stretch intensity of complete water base hard polyurathamc heat insulating material of the present utility model is high, and optimum with base adhesive, and with basic unit without cold-heat bridge, crack resistance is good, free from flaw, and this is that Conventional insulation cannot realize.
The rate of closed hole of complete water base hard polyurathamc heat insulating material of the present utility model is high, and can reach more than 92% (GB10799), moisture absorption moisture resistance is good, for roof, can realize thermal-insulating waterproof integration.
Other heat insulating material relatively, complete water base hard polyurathamc heat insulating material direct spraying of the present utility model forms in basic unit and forms complete water base hard polyurathamc insulation water-proof layer, without the need to being prefabricated into special shape, also fit tightly with basic unit without the need to being realized by adhesive, its convenience in forming materials, construction and installation is its unrivaled advantage.
