Abstract
The invention discloses a prestressed reinforced concrete sandwich heat insulating roof-panel which is characterized in that the reinforced concrete sandwich warming roof-panel comprises a reinforced bar concrete bottom board 1, a concrete face plate 2, a heat insulating concrete vertical and horizontal rib 3 and light heat insulating sandwich blocks 4 which are embedded in the reinforced bar concrete bottom board 1, the concrete face plate 2 and the heat insulating concrete vertical 3 at interval. The prestressed reinforced concrete sandwich heat insulating roof-panel is also characterized in that reinforced bars in the reinforced bar concrete bottom board 1 are prestressed reinforced bars 5. The heat insulating roof-panel integrates the bearing of the structure and the heat insulation and has the characteristics of light dead-weight, good structural performance, heat insulation and sound insulation, rapid and convenient construction, low cost and the like and is a new green energy-saving roof panel material with excellent cost performance.
Description
Technical field:
The present invention relates to a kind of sandwich thermal insulated roof panel of prestressed reinforced concrete that is used for building roofing.
Background technology:
Along with China's rapid growth of economy, the energy starved crisis also increasingly sharpens, according to the relevent statistics data; in the energy consumption total amount; building energy consumption accounts for greatly more than 20%, and for guaranteeing the sustainable development of China's economy, building energy conservation has become the most important thing of China's energy conservation.Roofing is the important ring in the building energy conservation work as the peripheral structure of building.At present for the building on flat roof, energy-saving design in construction commonly used is to do one deck thermal insulation layer on roof panel, to satisfy the design standard of building energy conservation, though the way in the heat insulation room of roof heat insulation is a lot, no matter but adopt the heat insulation room of which kind of roof heat insulation way, one will increase working procedure, and two will increase construction cost.Therefore, if can develop and a kind ofly can satisfy building energy-saving standard, can try one's best does not again increase the advanced composite material (ACM) of roofing construction cost roof panel, for carrying out building energy-saving standard, particularly in the housing construction of vast small towns, carry out building energy conservation work, have the effect of getting twice the result with half the effort significantly.
Summary of the invention:
The object of the present invention is to provide and a kind ofly structure load-bearing and thermal insulation are integrated the sandwich thermal insulated roof panel of self-heat conserving prestressed reinforced concrete that quick construction is easy, cost is low.
The technical solution used in the present invention is: the sandwich thermal insulated roof panel of prestressed reinforced concrete comprises the prestressed reinforced concrete base plate, and concrete panel and insulation concrete rib in length and breadth, several light heat-insulating sandwich pieces are embedded in base plate, panel and in length and breadth among the rib equally spacedly.
In order to improve crack resistance, strengthen rigidity and bearing capacity, described base plate adopts prestressed reinforced concrete.
In order to reduce the heat bridge influence, described insulation concrete rib in length and breadth adopts capacity less than 1000kg/m
3, intensity is greater than 7.5MPa, causes the light heat-insulating concrete of coefficient less than 0.5W/ (mk).
In order to improve heat insulating effect, light heat-insulating sandwich piece adopts the heat insulator of coefficient of thermal conductivity less than 0.05W/ (mk).
Because the sandwich thermal insulated roof panel of prestressed reinforced concrete of the present invention, adopt dense rib sandwich form of structure, structure load-bearing and thermal insulation are integrated, pressing from both sides hot piece adopts heat insulator, close rib to adopt the insulation concrete, upper and lower panel is a deck, the middle level is the thermal insulation layer, the mechanical characteristic that had both met plate has reached the requirement of thermal insulation again.Characteristics such as therefore, plate of the present invention has from heavy and light, and structural performance is good, and thermal insulation sound insulation, quick construction make things convenient for, cost is low are the good novel green energy-saving roof panel materials of a kind of cost performance, can be widely used in the superstructure and the roofing of various building constructions.
Fig. 1 is a structural representation of the present invention
The specific embodiment:
As can be seen from Figure 1, the present invention has panel 1, panel 2 and rib 3 in length and breadth, and several light heat-insulating sandwich pieces are embedded in base plate 1, panel 2 and in length and breadth among the rib 3 equally spacedly.Base plate 1 adopts prestressed reinforced concrete, and the plain concrete of panel 2 and base plate 1 same numeral, rib 3 adopts the insulation concretes in length and breadth, and the sandwich piece is the heat insulator piece.Manufacture and can on long line prestressed hollowcore slab pedestal, carry out, uphold and to have drawn prestressed reinforcement, improve shaper, for the first time the bottom board concrete, floating after quantity sandwich material piece equally spacedly.Pour into a mould in length and breadth rib insulation concrete, two cast panel concretes, floating behind vibration compacting then, kind the protecting of the demoulding can be played sheetpile to the length of time and put then.
