Compared with prior art, the multi-functional resins roof slab of double-layer hollow isosceles trapezoid of the present invention has following beneficial effect:
One, the multi-functional resins roof slab of double-layer hollow isosceles trapezoid of the present invention is heaving of the sea continuous structure, when bearing deadweight and external force increases the weight of, by micro-Telescopic of wave and isosceles shape, play the effect of uniform decomposition pressure and vibration force, the external pressure from upper plate plane decomposed, the area of plane adding upper and lower bottom plate is 1.5-2.5 times of the area of plane of upper plate, guarantee the stability of bearing pressure, and decrease pressure load.Be provided with reinforcing rib in the double-layer hollow structure of this upper plate, back and lower shoe, the double-layer hollow structure of upper plate, back and lower shoe be connected as a single entity, there is stronger bearing capacity.Double-layer hollow structure is made up of many grids, and the air in space seldom flows, be heat non-conductor, constitute not only heat insulation but also warming physical property, built internal conditions cool in summer and warm in winter, directly minimizing summer air conditioner refrigerating and winter heating installation energy ezpenditure.
Two, the graft type modified EPT resin copolymer of roof slab body surface spraying, there is outdoor high temperature resistant (>=90 DEG C) for a long time, the chemical physical stability of anti-severe cold (≤-45 DEG C) and high bonding grafting performance, add the physics and chemistry basis feature of the anti-aging and heat-resisting cold-resistant formula of PVC aggregate, the similitude combination of interior exterior materials material, consolidate cold and hot, contract the synchronism that rises, substantially prolongs the time of roof slab natural aging, after anti-aging test and the anti-aging pilot scale in 5 years of outdoor three place, take experimental data, substitute into the anti-aging formula of material, the total of scaling results is 20 years, exceed the expection use setting phase of 15 years.
Three, the aggregate formula of roof slab body can the geographic latitude in area that uses of roof slab according to the present invention and climatic characteristic adjust, with adapt to duration of sunshine in year of Different Climatic Zones, annual accumution, year alternating temperature and temperature difference per day feature, improve the suitable time of product.Frigid zone from the torrid zone of low latitudes to high latitude, in aggregate formula range of the present invention, in the torrid areas of low latitudes, although annual accumution is higher than refrigerant latitudes, daily difference is less, year alternating temperature less, under the protection of protective coating, PVC raw material adopts low numerical value, and other 11 kinds of raw materials adopt high numerical value, reach property of raw material complementation, product with stable quality, long-lived object; And at the refrigerant latitudes of high latitude, PVC raw material adopts high numerical value, and other 11 kinds of raw materials adopt low numerical value, reaches product with stable quality, long-lived object equally; As for subtropical zone and the area, warm temperate zone of middle latitude, then PVC raw material and other 11 kinds of raw materials all adopt intermediate value, also can reach identical effect.The qualitative and quantitative method of this kind of flexible allotment aggregate formula is the test that comes from for many years and apply on the spot, for new product provides the product economy value of reliable technical foundation and reality.
Four, the angle of back and upper plate or lower shoe place plane is 38-42 °, in upper plate, back and lower shoe double-decker, the thickness of individual layer is 1.1-2.5mm, distance in this upper plate, back and lower shoe double-decker between two individual layers is 8-20mm, the thickness of described reinforcing rib is 0.6-2.5mm, vertical distance between the upper surface of this upper plate and the soffit of this lower shoe is 35-60mm, and the horizontal range at the center of the lower shoe that the center of this upper plate is adjacent is 70-85mm.The setting of these sizes is more conducive to regulate the pressure of isosceles trapezoid and clear up cold and hot, that contracting rises by generation anamorphic effect, the physical strength brought in conjunction with the aggregate formula of roof slab body of the present invention and the count and check of toughness, the gravity pressure of roof slab adds the gravity factor such as constructor, sleet, confirms can be competent at completely and bear all above-mentioned pressure through many places application.
Five, the roof slab body two ends of monolithic extend to form the upper docking cantilever and lower docking cantilever that connect for adjacent two panels roof slab respectively, on this, docking cantilever is superimposed with each other when being connected with lower docking cantilever and forms the structure consistent with the heaving of the sea continuous structure of described roof slab body, after multi-disc roof slab is connected, overall structure is consistent, adhesives can be adopted when upper docking cantilever is connected with lower docking cantilever, or add fastened by screw, guarantee that connection is firm, safe, lasting.The face be superimposed between upper docking cantilever and lower docking cantilever is provided with concavo-convex reference column groove structure, prevents from connecting rear slip.The thickness of the integral thickness >=roof slab body after upper docking cantilever and lower docking cantilever are superimposed, guarantees that the mechanical strength of link position is greater than single piece plate, guarantees to be connected firmly.Upper docking cantilever and lower docking cantilever all from the back of roof slab body successively upwards, parallel and extend to form downwards, the end docking cantilever on when connecting is resisted against in the angle space that lower docking cantilever and back formed, the end of lower docking cantilever is resisted against in the angle space that docking cantilever and back formed, upper docking cantilever and lower docking cantilever are all fixed, and rainwater can be prevented, snow-broth penetrates into below roof slab.
