Description

A kind of roofworks system structure
Technical field
This utility model relates to a kind of building roof, particularly a kind of roofworks system structure.
Background technology
Traditional roof structure be usually set gradually on roof concrete sloping layer, vapour barrier, heat-insulation layer, waterproof layer, Fish tail and waterproof layer and surface layer etc..Due to the of material own and the restriction of form of construction work, existing roof structure is usually present following Shortcoming:
One, roof waterproof, insulation total system scheme easy to leak water, channeling water: roof structure tectonic remnant basin is complicated, Gong Renshi Work level is very different, and construction technology is numerous and diverse, and sloping layer, waterproof layer, heat-insulation layer, protective layer are all to be individually separated construction, different Cross-operation between operation easily interacts, destroys, incompatible situation that may be present between different materials, is difficult to protect Card construction quality and reliability, cause building quality problems or hidden danger of quality often occur.
Two, roof waterproof, heat preservation construction are long in time limit: owing to construction technology is numerous and diverse, waterproofing and thermal insulation of roofing require long in time limit, Cost is high, and particularly direct and that structure sheaf is compound sloping layer needs to wait that final set just can carry out next step construction, expends the time Longer, the multi-layer compound structure of sloping layer top construction simultaneously, layer load is heavier easy to crack.
Three, roof waterproof, insulation do not reach environmental protection, power conservation requirement: the isolating membrane of existing waterproof roll SBS is regeneration Material, reduces the function of coil waterproof layer, and SBS is also mixed with certain shoddy simultaneously, have impact on the quality of modified pitch, and Environment is added pollution.Roof heat insulation typically uses warming plate or graininess insulation material, warming plate or heat-insulating granules material A complete insulation face cannot be formed when doing heat-insulation layer, and not reach intended heat insulation effect, to protective layer or levelling, look for Slope layer all can cause impact in various degree.
Four, seamless, globality are not accomplished in roof waterproof, insulation: polyester blank employs chopped fiber and uses starch gluing Close, it is difficult to basic unit's overlap joint and the bonding of overlapping the slot.
Five, set spray polyurethane foam adiabator layer on foam cement sloping layer to accomplish that percolating water is the most point-to-point and repair The effect mended: waterproof layer is arranged at the medium position of roof construction layer, and the breakthrough on structure top layer is not often to ooze really Leak source, it is impossible to be accurately positioned, needs significantly to repair structure sheaf, constructs loaded down with trivial details, and workload is big.
Utility model content
The purpose of this utility model is to provide a kind of roofworks system structure, will solve existing roof structure and construction Easy to leak water breakthrough water, construction period length that method exists, do not reach environmental protection and energy saving and require, do not accomplish seamless globality and cannot Carry out the technical problem of point-to-point repairing.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of roofworks system structure, including the top board structure layer spray coating heat preservation waterproof layer being combined the most successively, Cast-in-situ thermal-insulated sloping layer and spraying waterproofing protection surface layer;
Described spray coating heat preservation waterproof layer is hard-foam polyurethane layer;
Described cast-in-situ thermal-insulated sloping layer is bubble concrete layer;
Described spraying waterproofing protection surface layer is polymer cement anti-cracking and waterproofing mortar layer.
Spraying main water barrier also it is compounded with between described top board structure layer and spray coating heat preservation waterproof layer.
Described spraying main water barrier is rapid hardening rubber asphalt waterproof coating layer, single-component polyurethane water-proof paint layer, wet solid Change polyurethane water-proof paint layer, acroleic acid macromolecular waterproof coating layer, JS polymer waterproof coating material layer, organic silicon water-proofing dope layer Or uncured waterproof coating layer.
Also being compounded with spraying additional waterproof course between described top board structure layer and spraying main water barrier, this spraying is waterproof additional Layer is identical with the composition of spraying main water barrier.
Isolated protective layer, described isolated protective layer also it is compounded with between described spraying main water barrier and spray coating heat preservation waterproof layer For film layer.
Compared with prior art this utility model has the characteristics that and beneficial effect:
Roofworks system of the present utility model is existing integral roofing engineering system, reach national requirements energy-conservation, Environment protecting, using direct spraying water-repellent paint in structure roof is main water barrier, can preferably combine with structure sheaf, spray Painting hard-foam polyurethane is insulation water-proof layer, and protection waterproof layer slows down waterproof layer while avoiding being destroyed and changes because of outside climatic And cause aging, reach one-level water protection standards, cast-in-place foamed concrete for insulation sloping layer;Sprayed-on polymer cement cracking resistance is prevented Water mortar is protective layer.
This utility model the most all can improve waterproofing and thermal insulation of roofing effect as waterproof layer, improves finished product protection effect;Every Thermosphere contactless and gap, heat-insulation and heat-preservation is good, saves the step of plate cutting and installation.Spraying hard-foam polyurethane, cast-in-place foamed Concrete, sprayed-on polymer cement anti-cracking and waterproofing mortar all can be as heat-insulation layers, even if there being certain layer of inefficacy, remaining structure also can be very Good protects roofing.Compatible complementarity between material more can ensure that waterproof layer, heat-insulation layer complete, reduce extraneous from So factor changes waterproof layer, the destruction of heat-insulation layer.And entire infrastructure is mechanized construction, seamless ne-leakage.
This utility model speed of application is fast, and the construction period is short, and roofing overall cost is low, and manpower thing is saved in Fully-mechanized construction Power, sloping layer and surface layer be positioned at the top of structure sheaf, finally construct, eliminate prior art waits sloping layer final set time Between, the reduction of erection time.
Employing of the present utility model direct spraying water-repellent paint in structure roof is main water barrier, the seepage on structure top layer The real breakthrough of the i.e. waterproof layer of point can directly be accurately positioned, it is not necessary to significantly repairs structure sheaf, construction letter Single, workload is little.
