Technical field
The present invention relates to a kind of sloping roof structure and construction method thereof.
Background technology
Traditional sloping roof structure and construction method thereof also exist following shortcoming and potential safety hazard.
The insulation layer of 1, traditional sloping roof structure is equipped with more concrete leveling layer, corresponding construction method is wet construction, so complexity of not only constructing, and the easy contaminated environment of wet construction, destroy roofing attractive in appearance.
2, traditional sloping roof structure is equipped with concrete leveling layer more on insulation layer, and the weight of concrete leveling layer is very large, so can increase the load of roofing.
3, traditional sloping roof structure is firm not, the gradient of pitched roof is maximum can not more than 75 °, especially the longitudinal batten downstream in sloping roof structure is pasted onto on concrete leveling layer, along with the impact that concrete leveling layer is colded and heat succeed each other, longitudinally batten easily comes off downstream, especially easily occurs potential safety hazard.
4, traditional sloping roof structure effect of heat insulation is poor, and easily produces cold-heat bridge, so can have influence on heat supply and the refrigeration usefulness in house, is unfavorable for energy-conservation.
The life-span of 5, traditional sloping roof structure is relatively short.
6, traditional sloping roof structure cannot adjust the injustice of roofing, so tiling is easily uneven.

Compared with prior art the present invention has following characteristics and beneficial effect:
The maximum advantage of the present invention is that heat-insulating capability is splendid, properties of heat preservation and energy saving is good, effectively can regulate the conduction of heat on roof, greatly can improve the energy-saving effect in house, because: 1, warming plate, longitudinal batten and aluminum foil coiled material downstream define longitudinal confined air gas-bearing formation, and longitudinal confined air gas-bearing formation is Stilt layer, can prevent summer hot outdoor air from directly entering indoor, indoor heat can be stoped winter to be lost to outdoor, to serve the effect of heat insulation and Winter protection in summer; 2, warming plate, longitudinally longitudinal confined air gas-bearing formation of surrounding of batten and aluminum foil coiled material downstream, the transversal ventilation air layer surrounded with roof tile, aluminum foil coiled material and horizontal tile hanging batten is combined, define separate double-deck air interbed, this structure not only effectively can reduce the thickness of warming plate, enough ventilating heat-proof sheaf spaces can also be ensured, make pitched roof while having good ventilated function, can also prevent hot air from directly entering indoor, further enhance the heat insulation and preservation effect on roof; 3, longitudinal batten is downstream arranged on the upper surface of warming plate by bolster support, and warming plate is completely layered on waterproof bed course, so ensure that sloping roof structure does not have cold-heat bridge.
Warming plate in the present invention, longitudinally batten and aluminum foil coiled material define longitudinal confined air gas-bearing formation downstream, this structure also has a benefit, that is exactly longitudinal confined air gas-bearing formation is Stilt layer, when winter, indoor/outdoor temperature-difference was large, longitudinal confined air gas-bearing formation can cushion temperature difference as air layer, avoid roof tile produce condensed water in a watt bottom and cause freezing, and then extend the structural life-time of pitched roof.
Present invention eliminates the concrete leveling layer of construction on insulation layer, the bolster support be fixed on waterproof bed course is adopted to connect longitudinally batten downstream, the benefit done like this, one is be bonded on concrete leveling layer with longitudinal batten downstream to compare, the structure that longitudinal batten is downstream connected on bolster support is simpler, also safer firmly (namely longitudinally batten is not easy to come off downstream), two is compared with construction concrete leveling layer, the construction of bolster support is more easily simple, three is by the link position of adjustment bolster support with longitudinal batten downstream, the installation height of longitudinally batten downstream can be controlled, thus just can control the installation height of horizontal tile hanging batten and roof tile well, that is, adopt bolster support just can regulate height according to different pitched roofs, and then ensure the smooth of whole roofing, overcome the problem that tiling is easily uneven.
In the present invention, bolster support is connected on cement mortar screeding layer, longitudinally batten is connected on cement mortar screeding layer by bolster support downstream, what longitudinal batten was downstream connected with concrete base layer becomes more firm, simultaneously, warming plate is embedded on bolster support, thus make warming plate also define an entirety with concrete base layer, so make warming plate also more be securely fixed on the concrete base layer of pitched roof, the weight of adding whole pitched roof has in addition had very large alleviating (because eliminating concrete leveling layer), finally make the gradient of pitched roof can reach 90 °, far beyond traditional roof pitch is maximum can not more than the upper limit of 75 °.
The present invention is simple and safe, overturn and adopted concrete leveling layer to do the conventional thought of topping, the longitudinal direction changed in sloping roof structure lays the scheme of aluminum foil coiled material downstream between batten, the benefit done like this is: after 1, eliminating concrete leveling layer, the present invention will become a kind of dry construction technology, compensate for the deficiency of traditional cement mortar construction (wet construction), there is the free of contamination feature of work progress, pitched roof can be made to construct and to become simplification, and improve the aesthetic measure of elevation of building; 2, aluminum foil coiled material has the function of heat-insulation and heat-preservation; and can heat radiation be shielded; the heat-insulating capability of roofing can be significantly improved under the prerequisite not affecting roof heat insulation performance; thus improve summer energy-saving effect and the Winter protection effect of building; aluminum foil coiled material can also protect insulation layer and waterproof volume layer not to be damaged, and aluminum foil coiled material can also guarantee that people can stand on roofing or weight can be placed on roofing.
Present invention eliminates concrete leveling layer, reduce the load of building.
The present invention can coordinate the fastening system of roof tile to use, safe and reliable.
