The specific embodiment
Embodiment 1
The building block of core foamed concrete self-heat conserving bridge cut-off is the superthin concrete shell penetrating no end, cavity tubular about in the of 1 shown in Fig. 1-2, filling-foam concrete heat-insulating slurry forms cement fly ash foaming body 2 formations in hollow, and pulverized fuel ash cement foam internal layer is the cellular structure that has hole.
Described building block is a rectangular shape, be divided into length three limits, be inlaid with insulation plate 3 on shell 1 long limit and the residing bottom surface of broadside along long side direction, be inlaid with insulation plate 3 at shell 1 broadside and the high edge direction of residing left surface of flash and right flank upper edge; The strip polyphenyl plate that described insulation plate is wide 40-80mm, strip polyphenyl plate are tiled on the shell 1, and a part is embedded in the shell 1, and remaining another part protrudes in the surface of shell 1;
Described strip polyphenyl plate is embedded in part in the shell 1, is respectively equipped with the draw-in groove of triangle indent corresponding to two end faces of shell 1 broadside, the corresponding shell 1 that contacts with it is provided with symmetrical triangular shape fin, strip polyphenyl plate and shell 1 are affixed with the tongue and groove form, form the bridge cut-off layer, foaming body is firm is attaching the composite concrete shell; During use, can effectively block the loss of heat.
Be to increase the intensity of building block, cement fly ash foaming body 2 intermediate lateral of in described tubular cavity, filling and be vertically arranged with from top to bottom conduct the interval with composite concrete supporting layer or the reinforcing rib identical material of shell.
During production, at first composite concrete is put into mould, appearance adopts the mechanical presses moulding to make vertically hollow fragment of brick composite concrete skin 1, pressure more than 12～15 MPas, the stone concrete shell; Housing two ends and bottom polyphenyl plate are combined as a whole with housing is disposable aborning; Adopt flyash, cement to make slurry then through physical blowing, again slurry is cast in the shell, after the steam-cured curing, obtain having the pulverized fuel ash cement foam internal layer 2 of the empty cellular structure of miniature sealing, pulverized fuel ash cement foam internal layer 2 and outer 1 strong bonded of composite concrete, thus polyphenyl plate bridge cut-off layer is embedded in the building block of formation core foamed concrete self-heat conserving bridge cut-off with the composite concrete skin closely by draw-in groove.
(1) composite concrete shell material weight is formed adoptable scope and is: Portland cement 20%, sand 20%, rubble 60%, and the water of above-mentioned three kinds of raw material gross weights 5%;
At first the raw material of composite concrete shell is stirred and put into mould, appearance adopts the mechanical presses moulding to make vertically hollow fragment of brick composite concrete shell 1;
(2) cement fly ash foaming body 2 raw material weights are formed adoptable scope and are: Portland cement 40%, flyash 40%, blowing agent 20%; When being mixed with the foaming slurry of cement fly ash foaming body 2, the weight content of water is 80% in the foaming slurry body;
Blowing agent weight is formed: 3% rosin, 2.4% vegetable oil and/or animal oil, 2.4% caustic soda, 2.6% gelatine or hide glue, 2.2% waterproof agent, 2.4% foam stabilizer, 1.9% milky white adhesive, 0.1% water-soluble resin (as phenolic resins), 3% wastes of crops (as: straw, maize straw);
Owing to adopt above-mentioned blowing agent to solve the problem that insulation blocks produces expansion, ftractures and subsides because of perfusion foamed heat insulating slurry concrete in the core after can moulding, make product one-shot forming aborning.
After the raw material of blowing agent mixed, to the water that wherein adds 10 times of blowing agent weight, with 80 ℃ stir into solution; Press 80% of cement fly ash foaming body 2 final total weight and be aqua, Portland cement 40%, flyash 40% and blowing agent are stirred in the cement, flyash slurry with the remaining water in back, under the high-speed shearing machine condition of stirring, foaming agent solution is poured into the foaming slurry of formation cement fly ash foaming body 2 in the cement, flyash slurry.
But the utility model core foamed concrete self-heat conserving bridge cut-off building block winter protection, fire prevention, antiseepage, insulation, load-bearing, it is the last reform of walling unit structure, original building block can not be satisfied existing people's habitat condition and satisfy the existing energy conservation standard requirement of country, main common fault: intensity is low, 5MPa is following, water absorption rate is big, frost resistance is poor, seepage, exterior wall decortication, shrinkage crack, be not incubated, and need do exterior-wall heat insulation; The body of wall horizontal mortar joint, owing to hollow reason, contact area is little and saturating cold, infiltration, antidetonation, decortication etc.; Bring difficulty and very high disadvantages such as maintenance cost to property management.
The characteristics of the utility model core foamed concrete self-heat conserving bridge cut-off building block are: intensity height, 15MPa be above, improve the antidetonation rank, bridge cut-off (blocking-up body of wall level, vertical mortar joint), antifreeze, impervious, winter protection, insulation (need not to do any insulation handles), ageing-resistant, permanent performance, easy construction, thoroughly changes the common fault of original standard brick and other building-block.And solve problem energy-conservation, insulation simultaneously, be the unrivaled new product of original materials for wall.
In a word, the utility model changes the block structure characteristics and solves the common fault of traditional building block, utilizes powder Coal ash and bridge cut-off layer solve wall thermal insulating, save the energy, price is far below the expense of external wall outer insulation; Increase exterior wall service life, fast, the plurality of advantages such as expense is low of beautifying the environment, construct.
