An assembled roof heat insulation device is used in the roof structure of a sloping roof. It includes a cuboid frame, the upper and lower surfaces of the frame are fixed with aluminum plates, and a ventilation channel is formed between the upper and lower aluminum plates fixed on the frame. The utility model utilizes the high reflectivity of the aluminum plate to isolate most of the solar radiation, and the absorbed solar radiation is transmitted to the air in the ventilation passage, and the hot air that is constantly heating up will rise along the slope direction of the roof and be discharged through the gap at the ridge, which is relatively fast. Cold air will be continuously sucked in from the gap at the eaves, and finally achieve the effect of ventilation, cooling and heat insulation. The utility model has good heat insulation performance, simple structure, convenient installation and low cost.
Description
Technical field
The utility model relates to the roof heat insulation heat-insulating technique, specifically is a kind of assembled type roofing heat-proof device, is applicable to the pitched roof building in city, hot area in summer, south and villages and small towns.
Background technology
Improve the heat-proof quality of roofing, most important to reducing outdoor hot environment and strong excessively solar radiation to the influence of indoor thermal environment, be important measures that improve indoor thermal environment.Traditional heat-preserved and heat-insulated roofing is on the deck on roof, and first guarantee for a person given by a shopkeeper's temperature isolation layer repaves the roofing that waterproofing course and topping are constructed, but this roof structure complexity, and also cost is higher, so the villages and small towns building of China seldom adopts.
Present China Xia Redong cryogenic region village-town house, the building of overwhelming majority pitched roof only is to prevent in the rainwater inlet chamber at the deck upper berth on roof one deck waterproofing course, the structure level that has lacked heat-blocking action, therefore cause pitched roof architecture indoor thermal environment poor, can only take other measures to satisfy the thermal comfort requirement of human body, such as at a large amount of electric fan, air-conditionings of using in summer, use charcoal fire, space heater winter.So not only caused energy waste, and can not be from improving indoor thermal environment in essence.
In addition, a large amount of at present pitched roof forms of using have 2 kinds: the one, and the wood structure pitched roof, the 2nd, the ordinary reinforced concrete pitched roof, the traditional heat insulation way of dissimilar roofings has very big difference, mutually can not be general, be unfavorable for the general of effective roof insulation technology and popularization, so be badly in need of now wanting a kind of general roof insulation technology solve the problems referred to above.
The utility model content
Defective at above-mentioned prior art, the utility model aims to provide a kind of assembled type roofing heat-proof device, can be applicable to the wooden structure or the ordinary reinforced concrete system pitched roof building in city, hot area in summer, south and villages and small towns, and heat-proof quality is good, simple structure, install convenient, be convenient to maintain and replace, and with low cost.
The technical solution adopted in the utility model is: a kind of assembled type roofing heat-proof device comprises the cuboid framework, and described framework upper and lower surface is fixed with aluminium sheet, and is fixed between the levels aluminium sheet on the framework and forms vent passages.Wherein said aluminium sheet is the low-launch-rate highly reflective material, reaches more than 0.8 for the thermal-radiating reflectivity of low temperature.Last lower aluminum sheet sticks on the upper and lower sides of plastic-steel framework or wooden frame by fluid sealant, and its junction is equipped with fluid sealant to reach good sealing effectiveness.Four jiaos of described framework are provided with fixing hole, so that when assembled type roofing heat-proof device is installed by framework, can be fixed on the pitched roof by the fixing hole of threaded spike and reservation.
Wherein the vent passages height is preferably 0.1m-0.3m.
The mechanism of heat insulation of roofing heat-proof device described in the utility model is: after being installed in roofing heat-proof device on the pitched roof, at first utilize the high reflection characteristic of levels aluminium sheet to come reflected solar radiation, reduce the radiations heat energy in the inlet chamber; On the other hand, enter heat in the vent passages that the levels aluminium sheet is configured on a small quantity and make atmosphere temperature rising in the vent passages, hot air will rise along the gradient direction on roof, discharge in space by the ridge place, colder air will constantly be inhaled into from the opening of eaves relatively, utilize the cooling effect of natural ventilation, further reduced the radiations heat energy in the inlet chamber.Wherein frame material is flitch or plastic-steel section bar, can effectively reduce the heat transmission by conductivity by heat-proof device.
In sum, the assembled type roofing heat-proof device that the utility model provides is applicable to wood structure or reinforced concrete structure pitched roof, can effectively improve the architecture indoor thermal environment, reduces room conditioning or heating energy consumption.

The specific embodiment
With embodiment the utility model is described further with reference to the accompanying drawings below.
Fig. 1 is the framework schematic diagram, and it highly is the vent passages 2 of 0.2m that framework 1 hollow forms, and length and width have multiple series, maybe can determine by actual requirement of engineering, the material requirements of framework 1 comprises wooden or plastic-steel section bar system for low Heat Conduction Material, transmits by the mode of conduction to reduce heat.Four jiaos of framework 1 are provided with fixing hole 3, are used for mounting strap screw thread spike 4.
Fig. 2 is an assembled type roofing heat-proof device unit module structure chart, comprises the aluminium sheet 5 of two same sizes, and aluminium sheet 5 smooth surfaces, and reflectivity height stick on the upper and lower surface of framework 1.Its middle frame 1 has played supporting role, makes things convenient for the workman to operate when mounted, and foothold is provided, and avoids aluminium sheet 5 stepped on collapsing.Aluminium sheet 5 sticks on the framework 1 by fluid sealant, and stickup need be tight, seamless, to avoid influencing the ventilation effect after building up.In addition, when actual installation, the roofing heat-proof device length of next-door neighbour's ridge is different, determine length according to actual conditions, can adopt the site operation mode to make.
Fig. 3 is the combination schematic diagram of assembled type roofing heat-proof device: when a plurality of assembled type roofing heat-proof device unit modules at the scene during amalgamation, the slit between the unit module need be filled with sealing joint strip 9, use fluid sealant bonding again, should note guaranteeing airtight, seamless.
During installation, directly assembled type roofing heat-proof device is lifted on the pitched roof, the fixing hole 3 at four angles hammers into roof truss structure layer with threaded spike 4 by fixing hole 3 over against above the roof truss structure layer on the framework 1, and roof covering heat shading apparatus is fixed on the roofing.With similar approach a plurality of roof covering heat shading apparatus are installed, are laid roof tile or ornament materials more above it.
With reference to Fig. 4, the operating principle of this device is: the solar radiant heat major part that is radiated at the roof is by upper strata aluminium sheet reflected back sky, the air space that the part solar radiant heat that absorbs will be formed by lower floor's two-layer aluminium sheet of aluminium sheet reflected back, behind the absorption of air heat, form thermal current, rise along the gradient direction of roofing subsequently, discharge, and promote the opening at eaves place constantly to suck cold air to replenish by the gap that the ridge place reserves.Thereby avoid in the solar radiant heat inlet chamber, can effectively improve Indoor Thermal Environment in Summer.
