Abstract
The invention discloses a kind of preparation method of cast-in-place LOFT floor plates, Secondary Design construction is carried out after civil engineering completes major project, the processing step of preparation method is, weldable steel expanded metals on above-mentioned i iron and channel-section steel, again by galvanized steel wire netting and expanded metal lath colligation, pour into a mould DFB light aggregate afterwards, and polyphenyl plate is buried underground side by side in DFB light aggregate, glass fiber grid cloth is laid respectively in the middle of the DFB light aggregate of polyphenyl plate upper and lower, after DFB light aggregate is poured into a mould, levelling, make real and treat that it solidifies, then smear crack-resistant layer cover with mortar.This preparation method does not need formwork, improves efficiency of construction, and its unit weight is light, intensity is high, can meet requirement of strength completely.Simple and direct easy to operate, the energy-conserving and environment-protective of this method manufacture craft.High, the overall fire line of the LOFT lightweight produced, intensity is good, is a complete process technology easily promoted.
Description
Technical field
The present invention relates to a kind of building floor, refer in particular to a kind of preparation method of cast-in-place LOFT floor plates.
Background technology
The manufacture craft of current LOFT floor is generally first select work steel or channel-section steel square tube to do structure, then spreads wood flooring or checkered steel plate above.But this structure is not prevented fires, non-moistureproof, and sound-proofing is poor.Develop intensity in a kind of structure high, sound-proofing, overall performance are good, and the manufacture craft of quick construction LOFT floor is easily required for market.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method of cast-in-place LOFT floor plates, this preparation method is a kind of quick construction new technology easily, made floor plates environmental protection, lightweight, intensity are high, and sound-proofing, overall performance are good, and can arrange in floor plates to lay floor heating pipe.
The technical problem to be solved in the present invention is realized by following scheme: the preparation method of cast-in-place LOFT floor plates, Secondary Design construction is carried out according to the general layout of construction site after civil engineering completes major project, i iron and channel-section steel structure will meet the force request that weighing apparatus carries, it is characterized in that: the processing step of preparation method is, weldable steel expanded metals on above-mentioned i iron and channel-section steel, again by galvanized steel wire netting and expanded metal lath colligation, pour into a mould the DFB light aggregate that thickness is 60-120mm afterwards, and in DFB light aggregate, bury one piece of block polyphenyl plate side by side underground, in described polyphenyl plate, two layers and one deck glass fiber grid cloth is laid respectively in the middle of the DFB light aggregate of below, after DFB light aggregate is poured into a mould, levelling with large thick stick, and made real with trowel and treat that it solidifies, then crack-resistant layer cover is smeared with DFJ sizing material and light-water sand by the mortar that 1: 4 weight ratio stirs into, its thickness is 10-15mm, one deck glass fiber grid cloth is laid in the middle of crack-resistant layer, do partitioning slot process during cover to complete, described DFB light aggregate is by magnesia, magnesium chloride, ferrous sulfate, hydrochloric acid and granular polystyrene composition, the percentage of gross weight shared by each component is: magnesia 30-50%, magnesium chloride 30-50%, ferrous sulfate 5-10%, hydrochloric acid 5-10%, granular polystyrene 5-10%.Described DFJ sizing material is made up of magnesium chloride, ferrous sulfate, hydrochloric acid, and the percentage of gross weight shared by each component is: magnesium chloride 70-90%, ferrous sulfate 5-10%, hydrochloric acid 5-10%, and the percentage by weight sum total of these three components is a hundred per cent.Described polyphenyl plate unit weight 15-25kg, is of a size of 1000 × 600 × 100, and longitudinal, horizontal spacing is 800-100mm.
Advantage of the present invention is: this preparation method does not need formwork, improves efficiency of construction, the light (80kg/m of its unit weight
2left and right), alleviate the dead load of civil engineering main body or steel work main body; Intensity high (0.9Mkp), can meet requirement of strength completely, and cracking-resistance load index is also far away higher than standard-required.This DFB light aggregate is A level incombustible material, combustibility (1..5 hour) and heat-insulating property (coefficient of thermal conductivity 0.1) good.Sound insulation 36 decibels, water absorption rate 3%, radioactive indicator is interior photograph index 0.13, outer photograph index 0.31.This method is successful experimental applications in engineering, and simple and direct easy to operate, the energy-conserving and environment-protective of its manufacture craft, comprehensive cost are low.High, the overall fire line of the LOFT lightweight produced, intensity is good, and being one has the better market space and the complete process technology easily promoted.

Detailed description of the invention
The preparation method of cast-in-place LOFT floor plates, carries out Secondary Design construction according to the general layout of construction site after civil engineering completes major project, and i iron and channel-section steel structure will meet the force request that weighing apparatus carries.Galvanized steel expanded metals 1 is welded on above-mentioned i iron and channel-section steel, again galvanized steel wire netting 2 is welded with expanded metal lath 1 colligation, expanded metal lath 1 overlap and periphery 3# band steel add strong weld (pad spacing is not more than 30), pour into a mould with DFB light aggregate 3 afterwards, its technological process is: smear first floor DFB and to gather materials 3 (20mm), and---paving glass fiber grid cloth 4 one deck---is smeared second layer DFB 3 (20mm)---paving second layer glass fiber grid cloth 4 one deck---that gather materials and is laid polyphenyl plate 5, polyphenyl plate 5 unit weight 20kg, be of a size of 1000 × 600 × 100, longitudinally, horizontal spacing is 100mm.As slope do not looked for by roof structure, available polyphenyl plate 5 looks for slope according to designing requirement---smears third layer DFB to gather materials 3 (20mm)---paving second layer glass fiber grid cloth 4---to drape over one's shoulders and smear the 4th layer of DFB and to gather materials 3 (20mm).After DFB light aggregate 3 is poured into a mould according to designing requirement, levelling with large thick stick, will gather materials to make real with trowel and treat that it solidifies.DFB light aggregate 3 solidifies rear DFJ sizing material and light-water sand stirs into mortar 6 by 1: 4 weight ratio, then on DFB light aggregate 3, one deck mortar 6 is smeared, then one deck glass fiber grid cloth 4 is spread, finally use mortar 6 cover (anticracking grout material 6 thickness is 10mm) again, partitioning slot process to be done during cover, and then do waterproof operation.Above-mentioned DFB light aggregate 3 is made up of magnesia 40kg, magnesium chloride 40kg, ferrous sulfate 6kg, hydrochloric acid 6kg, granular polystyrene 8kg mixing.Above-mentioned DFJ sizing material is made up of magnesium chloride 80kg, ferrous sulfate 10kg, hydrochloric acid 10kg mixing.
