Embodiment 1
Xi Kelu big dragon villa in March, 2014 renovation in Haikou is rebuild.Villa structural representation is shown in Fig. 3.Totally 4 layers, this villa, the 4th aspect amasss the half being about the 3rd layer.The balcony in the 4th layer of room is the roofing of the 3rd layer, adopts " ALFISOL IN CENTRAL engineering construction Generic Design In Architecture atlas " floor tile topping accessible roof way, arranges the light roofing system that the utility model provides on the 4th layer of roof.
The roofing way of the 3rd layer is specially: the 1:8 cement hydrophobic expansion pearlite arranging 1 road 20mm thick (thinnest part) successively on reinforced concrete roof board is looked for 2% slope, the 1:2.5 cement mortar screeding of 1 road 20mm, 1 road 1.5mm water-repellent paint, 1 road 1.2mm polymer membranes, completely spread 0.3mm thick polyethylene film one deck, 1:4 dry cement mortar that 25mm is thick, 8mm-10mm floor tile are paved and made real; Stitch the joint filling of wide 5mm-8mm, 1:1 cement mortar.3rd layer of roofing gross thickness is 75mm.
The detailed process that the roofing of the 4th layer is arranged: first adopt 1 road average thickness to be that the waterproofing mortar of 20mm is levelling and look for 2% slope; Sloping layer is brushed 1 road interface agent coating thickness and is about 0.03mm; After interface treating agent is dry, blade coating 1 road 2mm water-repellent paint in the interface agent coating formed, coating weight is 2.5kg/m
2, form waterproof coating; 2 times roof insulation coating brushed by waterproof coating, and forming thickness is the heat insulating coat of 0.08mm.
This project completes in by the end of April, 2014 in and comes into operation.In June, 2014, the surfaces externally and internally temperature of company to the 3rd roofing (balcony) and the 4th layer of roofing is monitored.
Follow-on test 3 days, test result is: the hot face temperature of the 3rd layer of roofing (balcony) ceramic tile reaches 59.4 DEG C, minimum temperature 29.8 DEG C; 4th layer of roof surface maximum temperature is 35.3 DEG C, minimum temperature 27.6 DEG C, and the hot face temperature of the 3rd layer of roofing is higher than the hot face temperature of the 4th layer of roofing 24.1 DEG C; Room ceiling surface maximum temperature 37.9 DEG C under 3rd layer of roofing (balcony), minimum temperature 27.3 DEG C; 4th layer of room ceiling surface temperature maximum temperature 35.5 DEG C, minimum temperature 26.3 DEG C, under the 3rd layer of roofing, room ceiling surface maximum temperature is higher 2.4 DEG C than low 4 layers of room ceiling surface maximum temperature.
Indoor environment temperature and the outside temperature difference of testing proof the 4th layer of room in actual use are very little, comparatively comfortable, are obviously better than room under balcony; And the indoor environment temperature in room is relatively high under balcony, air conditioner refrigeration effect is not remarkable, and energy consumption is larger.
Embodiment 2
One, Danzhou, Hainan, three floor self-built housing, originally roofing adopts cast-in-place concrete floor, and roof does not do waterproofing work, and roof surface adopts the 1:2.5 cement mortar screeding of 1 road average thickness 20mm to look for slope.Use roofing cement mortar many places after 2 years to occur serious cracking, cause roofing serious leakage.Solar radiation in summer is strong, and roofing maximum temperature is more than 52 DEG C, and house indoor ceiling temp reaches as high as 45 DEG C downstairs.Because ceiling radiant heat is serious, indoor under the condition of installing air conditioner refrigerating, indoor environment hot comfort is still very poor, and generally will arrive after ceilings cool down after 12 every night, air conditioner refrigerating ability is effective.
In August, 2013, the light roofing system that this self-built housing roofing adopts the utility model to provide: clean out and original look for slope-leveling layer; Brush 1 road thickness and be about 0.03mm interface agent coating; After interface treating agent is dry, the water-repellent paint that blade coating 1 road 2mm is thick in the interface agent coating formed, coating weight is 2.5kg/m
2; Finally brushing 2 times roof insulation coating on the waterproof coating formed, heat insulating coat thickness is 0.08mm.
After coming into operation, roofing temperature test result as shown in Figure 4 and Figure 5, Fig. 4 is the roofing hull-skin temperature curve map that the utility model embodiment 2 obtains, Fig. 5 is the roofing internal surface temperature curve map that the utility model embodiment 2 obtains, as can be seen from Fig. 4 and Fig. 5, at identical conditions, the hull-skin temperature of the original roofing of this self-built housing and internal surface temperature are all higher than the light roofing system that the utility model provides, after the light roof adopting the utility model to provide, roof surface temperature is the highest is no more than 37.3 DEG C, overhead room temperature is the highest 32 DEG C, with ceiling temperature close downstairs, indoor thermal environment obviously improves.And through tropical rainy climate more than a year, do not find Seepage.
As can be seen from the above embodiments, the light roofing system that the utility model provides is provided with sloping layer and/or leveling layer in roofing floor basic unit, thus makes the successful laying of follow-up interface agent coating, waterproofing course and heat insulating coat.Compared with the Roof system of secondary waterproof in " ALFISOL IN CENTRAL engineering construction Generic Design In Architecture atlas " in prior art, the light roofing system that the utility model provides greatly reduces building load, saves construction cost, improves building safety simultaneously.And, experimental result of the present utility model shows, the solar radiation of more than 80% directly can be reflected back space by the Roof system that the utility model provides, avoid Roof system accumulation of heat, significantly alleviate the urban heat land effect of hot summer and warm winter region, improve Interior Temperature Environment comfort level, and energy-saving effect is obvious.And, compared with concealed type water proof structure traditional in prior art, the Roof system that the utility model provides is exposed water proof structure, when waterproofing course occurs damaged, intuitively can carry out roofing investigation, and specific aim can be keeped in repair to the damaged part roof insulation coating or overlay coating with water-proof function, significantly reduces roofing maintenance cost.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
