The method for manufacturing aluminum electrolyzing workshop anti-cracking floor via combining heat resisting brick and integral concreting has the advantages that the heat resisting brick paved at the part terribly heated has the functions of heat resistance and free stretching; the integral face layer is hard to break at high temperature; the heat resisting stick having strength level not less than C35 can bear great load in production process; and the face layer and the floor structural layer comprise the condition of relatively free slipping.
Description
Technical field:
The present invention relates to the method for manufacturing aluminum electrolyzing workshop anti-cracking floor that a kind of heat resisting brick combines with monobloc cast, belong to aluminium electrolysis shop concrete floor surface layer manufacture technology field.
Technical background:
Aluminium electroloysis belongs to the high-temperature metal smelting process, and the aluminum solutions temperature in the smelting equipment electrolytic cell is up to 960 ℃, in the production operation except the high temperature aluminum liquation frequently water clock on flooring; Also need change the conductive anode carbon rod in turn; Its discarded high temperature anode scrap epicranium is changed down, is shelved on the steel carriage of flooring to carry out the nature cooling, during like upset operation; High temperature anode scrap head is directly lost and is placed on the flooring; Therefore flooring even receive nearly 600 ℃ width of cloth and penetrate heat effect, the operation of the heavy car of two-maing ladle in addition, thus make the concrete floor surface layer of present use Large Area Cracking occur, fall piece.This not only influences production, also threatens the safe handling of load-bearing reinforced concrete floor structure.Therefore, the concrete floor structure of existing aluminium electrolysis shop still can not meet the needs of production.
Summary of the invention:
The objective of the invention is: a kind of simple in structure, with low cost, easy construction is provided and has more to adapt to the heat effect performance, can prevent or alleviate the method for manufacturing aluminum electrolyzing workshop anti-cracking floor that the heat resisting brick of the rigidity flooring surface layer cracking that causes because of factors such as deck deflection deformation, immerge and temperature deformations combines with monobloc cast, to overcome the deficiency of prior art.
The present invention is achieved in that it comprises the aluminium electrolysis shop that is provided with aluminium cell; When making the flooring of aluminium electrolysis shop; Earlier produce the reinforced concrete floor deck, on the reinforced concrete floor deck, lay the pitch separation layer of one thickness≤1.5 millimeters thick then by traditional method, treat pitch separation layer drying after; In 800 millimeters scopes in frid limit of aluminium cell, with heat-resisting paving with mortar 60～80 millimeters thick heat resisting bricks; At 800 millimeters beyond the scope apart from the frid limit of aluminium cell, on the pitch separation layer, building one deck thickness is the pea gravel concreten surface layer of 60～80 millimeters thick then.
As stated above; After treating pitch separation layer drying, for result of use better, at 800 millimeters beyond the scope apart from the frid limit of aluminium cell; On the pitch separation layer, lay one deck reinforcing bar stratum reticulare earlier, on the reinforcing bar stratum reticulare, build the pea gravel concreten surface layer that a layer thickness is 60～80 millimeters thick then again.
When building the pea gravel concreten surface layer; The mode that employing is vibrated is built, behind the vibration compacting with smashing with smearing, and when building; The pea gravel concreten surface layer is separated into the pea gravel concreten surface layer of the rectangular block formula of 3～6m * 3～6m; Between the pea gravel concreten surface layer of per two adjacent rectangle piecemeals, be provided with width and be 15～20 millimeters straight joint, filling pitch flax silk in the seam of straight joint then, and have the top of pitch flax silk to put down straight joint with the bituminous grout embedding in filling.
The degree of depth of above-mentioned bituminous grout is 20～30 millimeters.
The pitch separation layer preferably adopts the bitumastic material to make.
The strength grade of above-mentioned pea gravel concreten surface layer should be not less than the C35 concrete.
Heat resisting brick can adopt concrete precast block to replace.
Owing to adopted technique scheme,,, under high temperature action, can reach following three kinds of physical and mechanical properties through the actual use proof of engineering by produced heat resisting brick and the compound anti-cracking floor of concrete of the inventive method.
1, heat resisting brick is paved in the most serious place that is heated, and not only heat-resisting but also can freely stretch, monolithic floor surface is not easy to crack under high temperature action;
2, strength grade is not less than C35, can bear the big load in the manufacturing process;
3, possesses the condition that is free to slide relatively between surface layer and the floor slab structure layer.
Therefore, the present invention compared with prior art has the following advantages:
1, owing to set up the bitumastic separation layer; Surface layer and deck are broken away from relatively; Can prevent the influence of facings such as deflection deformation of concrete structure layer and temperature deformation; Make both can be relatively movable, the mutual effect of constraint value of reason and cause the surface layer cracking not after being heated, this is to be different from the existing important crack control measures of ordinary concrete flooring;
2, concrete pavement is owing to be provided with piecemeal straight joint lattice, and forms independently fritter separate unit, its freely fringe conditions help freely stretching of small blocks itself, prevent to ftracture;
3, set up steel mesh reinforcement in the high-grade concrete surface layer, heat resisting brick is paved in the most serious place that is heated, and effectively solves concrete and meets problems such as heat cracking and exposure cracking, guarantees the stability of surface layer.
