A kind of overhead type heat preservation energy-saving roof
Technical field
The utility model relates to technical field of buildings, specifically, relates to a kind of overhead type heat preservation energy-saving roof.
Background technology
Steel frame-concrete core barrel structure is one of high residential building form of structure commonly used in recent years, as a kind of combination construction system, it has the advantage that the steel structure earthquake-resistant performance is good, speed of application fast and concrete core tube rigidity is big, amount of side-shift is little, cost is low concurrently, thereby development is very rapid.Research to steel frame-steel concrete core barrel structure at present is confined to the safety of structure aspect more, research contents biases toward dynamic characteristics research, structural design scheme comparison and the improvement etc. of structure under seismic loading, and the research of the space enclosing structure that matches with this system is less.Research at the residence energy saving aspect in recent years is subjected to paying attention to widely, but the achievement in research spininess to traditional structure and pure steel structure the residential building thermal technology detect and energy consumption analysis aspect, the energy-conservation research of the space enclosing structure of the steel frame of cold district-concrete core barrel structure still be blank.The Shandong Province had issued " Residential Buildings Energy 65% design standard " in 2006, and the building energy consumption of cold district is had higher requirement.
At present, the building roof of China is continued to use a kind of low usefulness roofing system always---by poor efficiency heat insulating material (as cement slag, expanded vermiculite, pearlite heat-insulation plate, foamed concrete etc.), poor efficiency heat-insulation system with cement mortar (or cement concrete) composition, after this appearance of inverted roof makes the roof water-proof problem obtain improvement to a certain degree, but the integral heat insulation performance on roof still is relatively poor.Along with improving constantly of design standard for energy efficiency of buildings, original roof structure far can not satisfy energy-conservation 65% new demand, and energy consumption is bigger.This is the deficiencies in the prior art part.
The utility model content
The technical problems to be solved in the utility model provides a kind of overhead type heat preservation energy-saving roof, and heat preservation and energy conservation effects is good.
The utility model adopts following technical scheme to realize goal of the invention:
A kind of overhead type heat preservation energy-saving roof comprises concrete roof plate, leveling layer, waterproofing course and insulation layer, and it is characterized in that: the upper strata of described insulation layer is provided with air space.
As the further qualification to the technical program, described air space upside is an insulating board, and the two ends of described air space are provided with one group of activity air door.
As the further qualification to the technical program, described air space is double-deck built on stilts cement tile.
As the further qualification to the technical program, described leveling layer is the cement mortar screeding layer.
As the further qualification to the technical program, described waterproofing course is polymer modified bituminous waterproof sheet material or polyurethane water-proof paint.
As the further qualification to the technical program, described insulation layer is an extruded polystyrene board.
Compared with prior art, advantage of the present utility model and good effect are: the utility model has been set up air space on the roof, at the air space two ends movable air door is set, air door can be opened the movable air door that the roof carries out air draft summer according to season and weather condition opening and closing, air space ventilates, can take away a large amount of waste heats, reduce indoor heat, winter, all movable air doors were closed, air space seals, and has increased the insulating power on roof.The utility model makes full use of insulation of occluded air interbed and the heat insulation characteristics of aeration air interbed, makes the roof on the basis that increases cost not significantly, has the good result of thermal-insulation energy-conservation, has satisfied " Residential Buildings Energy 65% design standard " requirement.

Fig. 2 is the preferred pitched roof structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment the utility model is done further to describe in detail.
Referring to Fig. 1, the utility model comprises concrete roof plate 1, leveling layer 2, waterproofing course 3 and insulation layer 4, air space 5, movable air door 6, insulating board 7, the upper strata of described insulation layer 4 is provided with air space 5, the two ends of described air space 5 are provided with one group of activity air door 6, described air space 5 upsides are insulating board 7, described leveling layer 2 is the cement mortar screeding layer, and described waterproofing course 3 is a polymer modified bituminous waterproof sheet material, and described insulation layer 4 is an extruded polystyrene board.Leveling layer 2 is the thick 1:3 cement mortar of 20mm, and waterproofing course 3 is coated with waterproofing course for spreading 3mm high-polymer modified pitch two cloth four earlier, spreads the 4mm polymer modified bituminous waterproof sheet material then on this basis; Insulation layer 4 is the thick extruded polystyrene board of 100mm, on overlay one deck guard shield, air space 5 is 200mm, insulating board 6 is the thick Canton-tile floor of 25mm.
Referring to Fig. 2, this preferred embodiment comprises concrete roof plate 1 ', leveling layer 2 ', waterproofing course 3 ' and insulation layer 4 ', air space 5 ', the upper strata of described insulation layer 4 ' is provided with air space 5 ', described air space 5 ' is double-deck built on stilts cement tile, described leveling layer 2 ' is the cement mortar screeding layer, described waterproofing course 3 ' is a polyurethane water-proof paint, and described insulation layer 4 ' is an extruded polystyrene board.
The utility model has been set up air space on the roof, at the air space two ends movable air door is set, air door can be according to season and weather condition opening and closing, open the movable air door that the roof carries out air draft summer, air space ventilates, and can take away a large amount of waste heats, reduce indoor heat, winter, all movable air doors were closed, and air space seals, and had increased the insulating power on roof.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model also is not limited only to above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also belong to protection domain of the present utility model.
