Description
(1) technical field
The present invention relates to the packing material in a kind of reinforced concrete hollow floor structure, especially a kind of expanded material aeration tank with enhancement Layer and slurry leakage hole and preparation method thereof belongs to buildings in general structure field.
(2) background technology
At building field, along with the large-span concrete structure is increasing, increasing floor adopts the hollow floor structure technology.Sometimes in order to reduce dead load or to strengthen concrete insulation, heat insulation, sound insulation, damping effect, need to place some lightweight fillers in the concrete the inside.Replace the part concrete substantially can not affect the stress performance of structure with lightweight filler, but the deadweight that can greatly alleviate structure.
From the construction angle, when packing material is tubulose or bar-shaped time construction most convenient, concrete is easily built closely knit." structural member for concrete thin-wall cylinder " arranged, and (ZL98231113.3) " fibre reinforced hollow thin-wall tube for filling in bar reinforced concrete and manufacture method thereof " (ZL99115649.8) and " having the light porous material obturator that the multiple section shape is used for concrete " early stage correlation technique such as (ZL02293406.5), but these technology have certain limitation, larger such as ZL98231113.3 and the formed packing material deadweight of ZL99115649.8, and north of china in winter can't be in outdoor production; The mortar class separation layer intensity such as cement paste is lower in the obturator of ZL02293406.5, often need to strengthen with reinforcing cage in the construction.I " a kind of light foam material filling member with reinforced hard " also once proposed (ZL200420077923.9) and " a kind of pin-connected panel with a plurality of cavitys is filled pipe " (ZL200420077924.3).Although ZL200420077923.9 also has very high practical value, ZL200420077924.3 is the convenient suitability for industrialized production that realizes again, but these two technology and foregoing technology all also belong to the category of filling pipe or filler rod, hollow building cover hollow rate with these Material Fillings is less, and the macroeconomic type is relatively poor.
In hollow building cover, the floor hollow rate maximum of filling with casing undoubtedly, dead load is the lightest.In the prior art, " a kind of shuttering member " that Mr. Qiu Zeyou is arranged preferably (ZL200310100971.5), " a kind of shuttering member " (ZL200310100972.X), " a kind of shuttering member " (ZL200310100969.8), " a kind of hollow component used for concrete " (ZL03118393.X), " a kind of hollow component used for concrete " (ZL03147388.1), " a kind of light carcass mould member for in-situ casting " (ZL03157893.4), " a kind of filling concrete in situ lightweight member " (ZL200310121942.7).Also have Cheng Wen Mr. Rang " thin wall box for filling cement building roof " (ZL01245232.7), Mr.'s Wang Benmiao " thin wall box in-situ poured concrete hollow slab thin-wall box body " (ZL02282207.0), " casing (fillet) " (ZL200530117113.1) with " casing (right angle) " (ZL200530117112.7) etc.
