Description
Technical field
The invention belongs to concrete structure reforming technology technical field, relate to and a kind ofly make the molten building renovation technique be integrated of new and old concrete.
Background technology
Modern building be unable to do without concrete.Concrete invention and use existing more than 100 year history, brings splendidness to modern architecture industry.But the technical barrier that long-standing problem new-old concrete can not moltenly be integrated, fails effectively to be solved all the time.To maintenance and renovation old building, generally all can make following construction processing: 1. suitably improve concrete strength, to increase adhesion stress; 2. by old concrete surface turk, to increase adhesive power; 3. old concrete is cleaned in cleaning, new-old concrete is contacted as far as possible tightr.
Above-mentioned measure has certain booster action, but fundamentally can not solve new-old concrete and to combine closely problem, will unclamp through new and old concrete after a while, peel off, come off.Trace it to its cause, be concrete ramming after three months, its inside will carbonize, and generates calcium carbide.Calcium carbide does not affect concrete intensity, but it can form separation layer at new-old concrete interface, has a strong impact on both combining closely, brings potential potential safety hazard to maintenance and renovation engineering.
Summary of the invention
For overcoming above-mentioned technical disadvantages, the invention provides one to repair most of obsolete building, the calcium carbide of old concrete interface can be removed, make that new-old concrete is molten to be integrated, what fundamentally can solve that new-old concrete combines closely problem makes the molten pickle that is integrated of new and old concrete and using method thereof simultaneously
.
The present invention solves the technical method that its technical problem adopts: a kind ofly make the molten building renovation technique be integrated of new and old concrete, and its processing step is:
The first step: intensity detection, destroys damage or the concrete that burns out of fire, measures the old concrete strength of residue with Schmidt hammer, and residue concrete strength >=1OO# (C1O) namely can be used as to strengthen mending repairs foundation admittedly;
Second step: calcium carbide detects, the old concrete of the part that staggers or destroy the old concrete of damage, dips in upper phenolphthalein liquid with cotton fibre and is applied to the old concrete of residue on the surface, show the old concrete of pink expression and carbonize, should carry out pickling after 1 minute;
3rd step: do template, carry out template by size, one side will be created smooth in order to the demoulding inwards, and ensure the quality of products for convenience of operation, column template should be divided into two to three joints;
4th step: pickling, wipes the concrete surface (not rinsing with water) of staggering clear with wet rag, dips in pickle and is evenly applied to old concrete surface, require once to complete, do not repeat after dry with bamboo band handle hairbrush;
5th step: smash pouring concrete, first installation form can be smash and water, sulfuric acid concrete wants on-the-spot artificial hand to fry, and now fries existing use, how many and how much fries, smash while insert real, namely install second section template and smash after having smash first segment and water, the one side of Section of three template will stay a breach (the top board place of post), finally fills up from breach charging, or from boring a hole upstairs, smashing and tamping from charging above to during capital;
6th step: form removal, concrete can remove template after smashing and watering 2 days, need not showering curing.
Its component of pickle and the weight ratio of described 4th step are: 27% commercial sulphuric acid 1.15 ~ 1.5, clean water 100.
Described 5th step sulfuric acid concrete 1m
3materials: 400 grade cement with 402 kilograms, the cobble smashed or granite stones (particle diameter 10mm) 0.82m
3, medium sand 0.63m
3, clean water 200 kilograms, 27% commercial sulphuric acid 2.21 kilograms.
Described sulfuric acid should load compared with heavy sheet glass bottle or solid plastic ware, and can not use ironware, operating personnel should be with safety goggles, mouth mask, Rubber gloves, wear anti-skidding rubber overshoes, in order to avoid burn.
Sulfuric acid, when preparing, should be poured into water by described pickle and sulfuric acid concrete slowly, with falling with stirring, water can not be poured in sulfuric acid, in order to avoid set off an explosion.
Rubble in described sulfuric acid concrete with the cobble smashed or granite, must forbid limestone.
Described pickle and can not disorderly falling everywhere for the surplus waste water of above-mentioned technique, care should be used to pours sewer into.
During the residual building of described first step detection of fires, for safety, should successively prick to shore in advance and prop up, make provision against emergencies.
Described first step intensity detection, successively should divide flooring, wall, post subregion multi-site determination, ensures that data are representative.
The invention has the beneficial effects as follows: 1, use this technique can repair the building of most of obsolete building, particularly concrete on fire; 2, can significantly reduce costs, the shortening time; 3, applying after the form removal of this technology need not trickle maintenance, can saving water resource and the energy, for the region that freshwater resources lack, has great meaning; In sum, pickling technical economic benefit, social benefit and ecological benefits are remarkable, and technology maturation is practical, the feature that DEVELOPMENT PROSPECT is wide.
