Description
Technical field: the invention belongs to the building class.
Technical background: amount of reinforcement is many in the existing reinforced concrete structure, the cost of providing fortification against earthquakes height, and complex process, and the stress of steel does not obtain performance fully.Task of the present invention is at not enough in bridge and the house architectural structure, and a kind of earthquake-proof energy-saving concrete structure is provided.
Summary of the invention: content of the present invention is: reinforcing bar is used steel sheet and steel band instead in bridge and the building construction concrete structure, the invention is characterized in, the shell of concrete member or hollow inner casing all adopt steel sheet, and the reinforcing bar in the concrete structure is used steel band instead.
Earthquake-proof energy-saving concrete structure of the present invention, technical characterictic is that changing the reinforcing bar in the existing concrete into steel band uses, steel band is twisted into fried dough twist rod type, the steel strand band that steel band is stretched, the twisting processing technology is made, constitute the steel strand band with the equal effect of prestressing force, have high strength bearing capacity concrete structure main part.The Bian Labian strand processing technology of steel strand band has increased anti-folding and tensile strength greatly, can improve the shockproof shock-absorbing of component strength grade, also can reach the purpose of material saving.The steel wire binding bar of member and construction formwork all adopt steel sheet; be the concavo-convex steel sheet of curve with the steel sheet roll forming; the concavo-convex steel sheet of curve two sides adds steel band; through the hard and soft coexistence of the concavo-convex steel sheet of transversal reinforcement curve; constitute the concavo-convex steel sheet of transversal reinforcement curve with bearing capacity; make the concrete component housing and both substituted construction formwork, substitute concrete member stirrup again, the flexible strength of its shell plays the fracture of concrete member and broken protective effect.Its principle is structure before destroyed, the transversal reinforcement electric welding of the concavo-convex steel plate of transversal reinforcement curve breaks away from earlier, the concavo-convex steel sheet of curve will slide by fair curve, or else it produced pulling force, the concavo-convex steel sheet of shell curve of member just can not be fractureed, and can ensure that concrete structural element housing is complete, just can slack time collapse to the time of an escape of people, perhaps, the concavo-convex steel sheet of curve complete behind the house collapse can play people's living space by bracketing, thereby reaches anti seismic efficiency.
Earthquake-proof energy-saving concrete structure of the present invention, raw material steel sheet, steel band all are that coiled material is littler than reinforcing bar volume, are convenient to transportation, storage, any length of member does not produce stub bar, material saving all without grafting.Existing steel band material difference, the production technology difference, kind, material are selectively big.Stretched, twisting processing technology constitutes the steel strand band of the equal effect of high-intensity prestressing force, and the tensile strength that obtains embodying in its concrete structure in experimental data is than more than the reinforcing bar Senior Two times.Three factors that can improve stress are arranged theoretically, the one, cancelled the elongation per unit length of steel behind the drawn, the 2nd, after twisting, become band circular arc and great waves S type and improved its bending resistance, the 3rd, created the triangular arch power with circular arc by second, the Any shape of having broken steel all can not change its tensile strength theory.The price height of high-strength steel strip, than amount of reinforcement much less, price differential and amount difference are adjusted the result, and more than 60 percent, monetary savings is more than 30 percent with the saving of steel strand carrying material.General band relative material saving amount is few, and price differential is also few, and monetary savings is still made no distinction of rank.Steel sheet is selected materials, and the material pliability is good, and steel plate thickness gets final product at 0.25mm to 0.4mm, can offset the template expenditure fully, the concavo-convex steel plate of transversal reinforcement curve has stronger rigidity, can substitute steel wire binding bar and construction formwork, therefore also can save the steel of part stirrup.Steel strand band and the whole connection method of the concavo-convex steel sheet of transversal reinforcement curve do not have can directly put into component housing after the moulding of flexible steel strand band, as long as the steel part anchoring is crossed at two ends, whether interlude wants anchoring to look the element structure needs.Have when Elastic Steel strand band is installed and want twisting to fix, steel strand band arranges eyelet and is convenient to fixing and twisting, the steel strand with on the hole cross steel part and fix an end earlier, fixedly the preceding twisting of the other end once can strain at firmly.Some member stomach wall will with round steel cross steel strand with on hole and the hole on the concavo-convex steel sheet of transversal reinforcement curve add crotch and draw solid.If wooden form just can only be used bolt draw bar.The elongated main part steel strand band of beam is installed in the bottom of member, the top of beam has 1/3rd long negative part steel strand bands to get final product, the top interlude steel strand band of beam can omit, and the concavo-convex steel plate of transversal reinforcement curve can substitute stirrup, can also substitute the effect of top part interlude main part.Steel strand is with and tightly packedly also can not be poured into by shielding concrete together, and being better than reinforcing bar need be with cushion block and pad muscle, and the saving of labor goes back material-saving.Different with reinforced steel bar strength according to steel strand band strength, need the long-pending back of converting of steel product cross-sectional to use.Processing technology is simple, and steel sheet is the concavo-convex steel sheet of curve through roll forming, and the concavo-convex steel sheet of curve two sides transverse spot, self-tapping screw or the fixedly connected method of rivet can add steel band, namely constitute the concavo-convex steel sheet of transversal reinforcement curve.Steel strand is with at the construction field (site) Mechanized Processing or artificial to realize, as long as a firm support is arranged, steel band Bian Labian strand is made the steel strand band of fried dough twist rod type, just uses indigenous method when the present invention researches and develops, and process velocity, molding effect are all fine.
