Description
Technical field
The invention belongs to light body roofing slab and the application thereof of the material insulation of a kind of province.
Background technology
At present in rural area, or the deck structure that Small Urban builds a house is to be located on surrounding roofing wall with roof truss beam triangular in shape interval, form with crossbeam each triangular roof truss beam that is connected to each other the integral support giving support to a roof again, then the baseplane of integral support forms indoor roof face with plate sealing again, and indoor roof face bottom is established decorative panel etc. again; The thick insulation layer of heap is filled out in indoor roof face upper end, for cold-proof, insulation and heat insulation.And the upper surface of integral support is conventionally triangular in shape, or arc forms outer roof, still form outer roof plan with the outer roof of plank sealing, the water layer of then setting up defences on roof plan outside again, on waterproofing course, establish tile hanging batten, cover tile is fastened on and on tile hanging batten, forms waterproofing course top.This traditional roof structure weight is large, expend that timber is many, construction speed is slow, cold-proof and insulation and heat-proof quality poor, do not prevent fires, construction cost is high.Even if with triangular shape roof truss beam replacement wood materials, the problems referred to above are still difficult to solve.
The building plane cement roof of modern architecture lacks insulation layer, also have that roof structure weight is large, consume material is many, construction speed is slow, cold-proof and insulation and heat-proof quality poor, do not prevent fires, deficiency that construction cost is high.
Summary of the invention
The object of the invention is to design a kind of province material is incubated and application, this light body roofing slab is had lightweight, intensity is high, turns waste into wealth, reduce and pollute, cost is low, and cold-proof and insulation and heat-proof quality are good, fireproof advantage, being applied in deck, to have consume material few, construction speed is fast, saves construction sequence, have cold-proof, insulation, heat insulation, fire prevention and energy-conservation and structure-integrated and with build same life-span, advantage that cost is low.
For this reason, the composition by weight of light body roofing slab material therefor of the present invention is, 250～260 parts of cement, 110～120 parts, flyash, 14～19 parts of particle light heat insulation materials, 1～1.5 part of polyvinyl alcohol, 0.5～0.7 part of cellulose ether, can disperse 0.6～0.7 part of rubber powder, 0.4～0.8 part of early strength admixture, water appropriate; The described light body roofing slab body that is rectangle, or rectangular body, side bottom is straight flange, the hypotenuse that side top is inside indentation; In described light body roofing slab, be provided with the cage of reinforcement being made up of vertical reinforcement and horizontal square reinforcing bar, four jiaos of steel plate reinforcing bars that are provided with on steel plate embedded part in cage of reinforcement bottom surface, are exposed at four jiaos of light body roofing slab bottom surfaces outside steel plate embedded part bottom surface.
The present invention is used in deck; Application process is: it is T-shaped that (1) is fixed with cross section on the steel truss giving support to a roof, or the clamping channel-section steel of L-shaped section, the distance on a side roofing between adjacent clamping channel-section steel and light body roofing slab length adaptation; (2) by the two ends broadside holding of light body roofing slab on clamping channel-section steel, being positioned at steel plate embedded part bottom surface on four jiaos of light body roofing slabs and the clamping channel-section steel of correspondence position is welded into one, each light body roofing slab is laid sealing deck side by side, and the connecting sewing of filling and leading up adjacent light body roofing slab surrounding with compo forms the smooth deck being made up of light body roofing slab; (3) set up defences successively in smooth deck upper end water layer, watt supporting layer and cover tile, forms the light body deck of economizing material insulation.Described steel truss is steel support triangle truss, or is steel support belfast truss.The cement mortar layer that described watt supporting layer is bonding cover tile, or for being pressed in the cover tile frame on waterproofing course.Said structure design has realized object of the present invention.
Light body roofing slab of the present invention has lightweight, intensity is high, turn waste into wealth, reduce and pollute, cost is low, cold-proof and insulation and heat-proof quality are good, fireproof advantage, being applied in deck, to have consume material few, and construction speed is fast, save construction sequence, have cold-proof, insulation, heat insulation, fire prevention and energy-conservation and structure-integrated and with build same life-span, advantage that cost is low.
Calculate according to side, the roof weight ratio tradition equal area structure that the present invention is every square metre is light by 50%.Anti-load improves 90%.Consume material few 50%.Thermal and insulating performance improves 80% than tradition, also saves warming and internal layer roofing construction step, has improved construction and construction speed.The present invention utilizes discarded waste old polystyrene foamed plastic material and flyash to make light body roofing slab, turns waste into wealth, and reduces and pollutes, cost 60%.
The basic technical indicator of the light body roofing slab of the present invention: dry density 280-300M
3, coefficient of thermal conductivity≤0.083W/mK, fire resistance rating is A2 level, freeze-thawing resistant detects indices through authoritative department and all meets the requirements.
