Description

Cross efficient high-strength indented bars and using method thereof
Technical field
The fast development of China's economic society, has effectively promoted the process of urbanization.The great development of urbanization has promoted the powerful tendency in premises markets more.City and country covers the building construction in building carrying out beyond example building a house on a large scale everywhere.Rural area is the new building of new house everywhere, stands in great numbers in cities and towns especially high building, towers into the clouds, and is more and more higher.People can't help asking? how solid do these tall and big buildings have actually? can it stand again the impact of much earthquakes? geology disasters is inevitable.Essential, concerning the safety of the people's lives and property, concerning descendants's safety.Can look down upon, can not regard as unimportant.Build room, build up building, reinforcing bar, cement, sand, stone are most important, the most basic, the most basic ingredients that builds modern architecture.Reinforcing bar, steel are the most important thing especially.How just can make reinforcing bar, steel are stronger, more solid, are only root problem.This problem is often appeared in one's mind in my brain, and the marking, in my soul, is day and night visited me and ground this difficult problem.To carry out a mechanics processing to plain bars.Carry out mechanics processing, set up the powerful high-intensity mechanics reinforcing bar of high mechanics system.
Background technology
I, my family stays in rural area in childhood, and family is being lived old house, is living this old dilapidated house and is being afraid of blowing and raining most, and noisy earthquake, is afraid of that room falls room and collapses especially, risks to human life.Tangshan Earthquake, Xingtai violent earthquake, Wenchuan violent earthquake is all that room falls the room threat to life that collapses, and kills a lot of people! Very disastrously very miserable! The marking is at me in the heart more firmly for it.What makes room fall room to collapse, and house has fallen in other words, and room just can fall down.It seems that our ancestors' logic of language is still very brilliant! First be that house has fallen, room just can fall down.So, my soul back warp often pondering allow house do not fall problem, the problem of earthquake-resistant building.Wanting house, not fall pillar be crucial, and pillar does not fall room and just not can fall, and room does not just collapse.Wanting pillar, to shake reinforcing bar be crucial.In order to build up house, in order to build the high buildings and large mansions that cast as iron and steel, allow common people live in the shockproof relieved good house not falling.We might as well first learn large tree, and I see and should be all right.That cloud-kissing large white poplar, that goes through the great Gu Chinese scholartree of centuries, even also has those to garrison all the year round the pine and cypress of the alpine rock on the teeth of the storm.They once went through century-old vicissitudes, and wind and rain blows and do not fall it, and does ground jolt and does not fall it why? is it also harder than the reinforced concrete of our high buildings and large mansions? tree also has the natural law and rule and the advanced mechanics principle that it survives itself greatly.Tall and big sturdy its branches and leaves of large tree are just more much more in great numbers, and the pressure that it bears and the power of rocking are just larger, and it is darker that its root will be pricked, and root system is more.Even own more strongly in violent storm do not sacrificed own aesthetic stature large tree root grown to ground in order to make, and around trunk the long large tree muscle of projection continuously that risen.This builds a house and builds building the spitting image of us again, and it is darker that the higher foundation in building will be dug, and building pedestal will be wider, and Here it is the mankind are at architectural bionics principle.Certainly also contained the reason of some mechanics; a lot of tree root tree muscle are played as for face length under trunk; also be in order to make the own strong reinforcement protection not falling to self, also as people for the sloping platform pillar that makes house or a wall and do not fall to build or the oblique wooden prop on top.Make people be subject to very large enlightenment.How just can make the pillars of a house, does Lou Zhu also think that large tree is equally strong and does not fall?
First should analyze the stressing conditions of cylinder, cylinder generally will be subject to the effect from two kinds of power of different directions, and one is gravity, also cry load-bearing, support force, it is vertically downward, the weight that they are carrying the whole building body on self weight and cylinder.Be one static, generally, be can overburden, be also relatively safe; Another is exactly the impact force from horizontal direction aspect from all directions, for example blow hard, typhoon, violent earthquake, making the earth building body rock this is not that static gravity bears, at this moment upstairs the weight of face has just become, rolling power, nosing force in left and right, north and south and other directions, impact force all around, it rock, swing and make whole building body prize building pedestal just as a lever, building body in distortion, this power is very huge, is the power that threatens and destroy the principal element of cylinder building.It is a motion, has very large kinetic energy.How could solve the hidden danger of this harm cylinder and building? increase the radical of reinforcing bar, increase the size (using thicker reinforcing bar) of reinforcing bar, this is fine certainly.This is a conventional method, but is not a method for economic science.Want economic the addressing this problem of science, also need to understand the problem that the directionality problem of the power that this destructiveness is large and reinforcing bar and concrete combination are solidified.Power has three elements, the size of power, direction and application point, the directionality problem of power and application point problem, we can be enlightened from the cage of large tree root projection and large tree muscle, and we can not allow reinforcing bar be exposed at the outside of cylinder building body yet certainly, can machinery yet apply mechanically, because there is the problem of individual combination between reinforcing bar and concrete, it is unlike large tree trunk and tree muscle one.We,, with the strong reinforcing bar of horizontal direction stress, also will adopt the solid especially firm reinforcing bar of being combined with concrete in addition, because reinforcing bar is proportional relation to the solid shaky size with rebar surface area of concrete combination.The superficial area of reinforcing bar is larger, and the area of its contact combination is just larger, more solid, firmer.The uniformity of cylinder and building body, integraty, globality will be larger, and cylinder will be stronger, more solid, firmer.So we,, adopting on the basis of indented bars, also should adopt the reinforcing bar that superficial area is larger to manufacture indented bars.
I think first to object classification; In roman, if in the equal object of superficial area, spherial body (spheroid) is the object of a unique volume maximum; If in the equal object of volume, spheroid is the object of a unique surface area minimum, and spheroid is again a unique object that holding capacity all equates on any direction in whole space (three dimensions), any point.It is real the first under heaven, and it is really very beautiful! Its occupy second be exactly square, if the volume of it and spheroid equate, its superficial area will increase a lot, the increase of superficial area makes the size of its holding capacity on whole square that variation occur.Its holding capacity in six planes equates, is also less, and its holding capacity on 12 ribs also equates, is also larger.Its holding capacity on eight corner angle (drift angle) also equates, is also maximum.If made comparisons with the equal square of volume and cuboid, cuboid has increased by 1/6th than the superficial area of square is minimum again, and superficial area has also increased a lot, and the big or small directionality of its holding capacity is just stronger.The still long body (cylinder the most relevant with our structural steel, Elliptic Cylinder, cuboid, Rhizoma Sparganii, four, five, six ...) if their volume length all equates, superficial area minimum be exactly cylinder, if superficial area and length all equate, cylinder is also unique of volume maximum in long body, it is the first under heaven in long body, if cylinder place vertical with horizontal direction in vertical direction, the holding capacity of any point in any one direction of its any one horizontal plane in the horizontal direction all equates, although first in its not all shaped objects, but it is first in all long materials, it is really also very beautiful! U.S.A is beautiful so it is also ruling steel market, is ruling structural steel market always! but it just seems somewhat unable to do what one wishes in face of violent earthquake, and its dynamics is inadequate, its insufficient strength in the direction of resisting violent earthquake.Its superficial area is minimum, thereby the area that contacts combination with concrete is also minimum, and the degree of being combined with concrete is also minimum.Thing respectively has its use, and shape respectively has its U.S., also respectively has it to use also.Steel market also should let a hundred flowers blossom and a hundred schools of thought contend, and particularly more should weed out the old and bring forth the new in structural steel market, constantly meets the needs of highrise building, meets the demand of quake-resistant safety house.We had introduced ellipse efficient high-strength indented bars and using method thereof, ellipse diamond pattern efficient high-strength indented bars and using method thereof.Oblate (flat ellipse) type efficient high-strength indented bars and make usage, T font efficient high-strength indented bars and using method thereof.The special cross efficient high-strength indented bars of promotion and using method thereof.Also will introduce from now on I shape, H font and two ellipse combined high-efficiency high-strength deformed steel bar muscle and using method thereof.They are all that sectional area girth is longer, and the directionality operations that superficial area is larger is more powerful, are applicable to very much the indented bars of modern concrete building.We first just imagine like this! If you have tied up the reinforcing bar shelf of a cylinder or the reinforcing bar shelf in whole floor room have all been tied up, do not give its joints cement, sand, stone slurry, can it bear great strength? obviously hold and can't stand that great strength will collapse; If a pillar or whole floor room, without reinforcing bar, are only starched and are built with cement, sand, stone, can it bear again great strength? also it also holds and can't stand great strength obviously.This explanation wants to make pillar not fall, and building is firm solid, and not only reinforced concrete sandstone slurry is important, condenses into that one just has powerful support force and the strength of the power that is hit but also will combine firmly.Whole pillar or whole building building could be solid firm, and their all reinforcing bars firmly could produce huge combination strength together with cement sandstone slurry, and the destructiveness that it just can not be afraid of violent storm and earthquake disaster attacks.Solve the solid problem of solidifying of reinforcing bar and cement slurry.Certainly most important with the quality of cement sandstone and reinforcing bar.But these problems we aside from.We only say that cement sandstone has direct relation with reinforcing bar in conjunction with the firm solid area solidifying that contacts with them solidifying.If their contact area is large, just large in conjunction with the area solidifying, certainly will in conjunction with firmly solid.Make the good integrity of whole cylinder; If their contact area is too little, in conjunction with area too little, certainly combination is shaky not firm.We just should manage to increase their contact area so, and we adopt round thread reinforcing bar to replace plain bar is exactly one of one of them technical measures.The object that we adopt round thread reinforcing bar is not the intensity that increases reinforcing bar, and is mainly the superficial area that increases it.The increase of superficial area is mainly the firmness degree that improves the reinforcing bar ability combination of being combined with concrete, and screw thread itself does not have the effect of gaining in strength.But this is not enough, we also will design to adopt the more long-pending technical scheme of large contact surface of greater strength, firmer more solid with concrete combination greatly at the architectural superficial area that we utilize it, on mechanics, in architectural critical moment of arriving in violent earthquake, we utilize the mechanics function of its high-intensity directionality.At the architectural long build reinforcing bar much in addition with these technical characterictics, equally also there is the elegance of T font efficient high-strength indented bars, cross efficient high-strength indented bars is again one of them.It also has than following the identical round thread reinforcing bar increasing section girth in its cross section, more increase the technical characterictic of superficial area, the increase of perimeter of section, not only increase the superficial area of cruciform reinforcement itself, its while has also increased length or the radical of screw thread, also increased the superficial area of screw thread, this has just more increased the intensity that cross indented bars is combined with concrete bonded area, what make that reinforcing bar is combined with concrete is firmer more solid, and it also has technical characterictic and the technical functionality of high-intensity directionality simultaneously.These technical characterictics are all that we will build the desirable structural steel that the safe house of high antidetonation is dreamed of.Can you not have ruler in the time that you chart in Learning in School Shi Huoni design studio? what also make with material regardless of it, it is exactly a flat cuboid, you just pick up this ruler, if towards in-plane (direction that plane is larger), slightly firmly a folding will be bending, if you turn 90 ° again ruler, firmly be twice and be also not easy bending towards the less direction of plane, the size of the holding capacity of Here it is ruler is directive.Does why not we are applied to the mechanics problem of ruler to manufacture have on more high-strength indented bars? build with it ferroconcrete prop not falling that is more added with powerful support force, construction can be resisted the high buildings and large mansions of violent earthquake.If we are two, identical, similar or different ruler-type reinforcing bar combines, longitudinally be separated into two ruler-types from the centre of a ruler molded breadth face, allow the side leptoprosopy of a little ruler vertically put together facing to the centre of another ruler length and width face, allow the side leptoprosopy of another little ruler-type vertically put together facing to Centromedian another plane of another ruler length and width face, allow them become as a whole.It has just become the reinforcing bar of a cross efficient high-strength.And bossed herringbone, crescent, spiral indented bars are made according to the external surface that needs using.Cross efficient high-strength indented bars not only has larger than the round thread rebar surface area of same cross-sectional, and the firmer more solid technical characterictic with concrete setting, more has the technical characterictic that holding capacity is more powerful, intensity is larger.Save in addition raw-material technical functionality.In the process of the long build object of research, find that holding capacity in object horizontal vertical direction is not only relevant with the size of the sectional area of object, but also relevant with perimeter of section, the shape in object cross section, superficial area, volume, the mechanical structure of object, also most important with the size of pressurized (stressed) distance of object.Also find simultaneously, if you want a round log rod or round iron (steel) rod to fracture, must there be three origin of force, if two, two origin of force is upwards, middle this origin of force is exactly downward, contrary with the origin of force direction at two, you centre what bear with force place is a normal pressure, what the end points from this application point to article diameters bore is a drawing tension.Be that starting point is pressurized (stressed) distance to the vertical distance (if stressed object is cylinder, namely cylindrical diameter) of the terminal of stress point from stress point.The cylinder movement locus that fractureed is taking application point as the center of circle, a semicircular arc taking pressurized (stressed) distance as radius, cylinder bending 180 °, although cylinder has fractureed, but also in succession constantly in stress point place, you want thoroughly to fracture it, and you must turn the direction of application point the angle of individual 180 °, namely just just can fracture it towards the opposite direction bending of former application point.This example is told when our active force acts on cylinder, the power acting on application point is normal pressure, the power acting on the end points of vertical lower of application point is drawing tension, its stressed kind is different, and size is also different, and what drawing tension will be large is many, so first it be pulled off, the power that they are subject to is unbalanced, and the normal pressure at stress point place is just little a lot, so it also constantly.Give one example again, if we take pocket knife laterally vertically to carve not bery dark tool marks at a round log rod, if allow tool marks side upward, masterpiece is used in tool marks place and exerts oneself downwards, these tool marks affect the size of its holding capacity hardly, if 45 ° of bag rotations, 90 °, 135 ° also affect the size of its holding capacity hardly, if Rotate 180 °, with the opposite direction starting, active force is acted on to the top on impressed opposite, the other end place of the diameter that namely impressed centre faces toward adds active force, have more than is needed very large strength has just fractureed it.This further proves in the time that you act on active force in the horizontal vertical surface of cylinder, it everywhere the size of holding capacity be unbalanced, so we just consider that position less holding capacity is reduced to a part allows concrete bear its effect, increases their stressed distances position larger holding capacity.We just adopt cross efficient high-strength indented bars.Cross indented bars can be set their size as required in the holding capacity of predetermined direction.Its holding capacity on vertical predetermined direction also can be set its size as required.It is with a wide range of applications and using value.It is at cylinder, Liang Ti, Lou Ti, prefabricated units, flatly waters, all very applicable in bridge, water conservancy projects and all reinforced concrete building engineerings.There is great economic benefit and social benefit.
Summary of the invention
We sum up in the analysis comparative studies of the object to various shapes (form) above.We have found to exist inherent contact between surface, volume, shape (form) and the holding capacity (power word structure) of object, the size of object energy holding capacity is not only relevant with the size of the volume of object, and also with the size of the superficial area of object, shape (form) and the related basic law of its mechanical structure of object.If the constancy of volume of object (timing), the variation (change) of body surface area, will inevitably cause the variation (change) of body form (form), the variation (change) of body form (form), also will inevitably make the variation of the mechanical structure of object change, thereby can cause object ability to bear (variation); If the shape of object (form) is constant, the variation of superficial area (changes, just will inevitably cause the variation (change) of object volume.Also can cause the variation (change) of the power that object bears.If its superficial area has increased, its volume and holding capacity all can increase, and vice versa.The table of object, shape, body, power are the elementals of object itself.Table is exactly that the surperficial size of object is how many, and shape is exactly shape, the form of object, and body is exactly that the size of volume of object is how many, and power is exactly the mechanical structure of object and size, direction and the application point of its holding capacity.Variation relation between them, is reflecting the inherent rule changing of object, and it has established the theoretical foundation of body mechanics, structural mechanics and engineering mechanics.Efficient high-strength and the larger firmer indented bars solidifying of being combined with concrete of superficial area that we produce various shapes according to this rule with regard to energy analysis interpretation research and design come.My object is not want increasing on the basis of indented bars sectional area (diameter) exactly, increases its holding capacity in so-and-so direction, and makes indented bars increase its superficial area simultaneously.What make that indented bars is combined with concrete is firmer more solid.Thereby make the cement pillar of steel concrete more strong, not askewly do not fall, make high-rise building more solid, firmer, more antidetonation.Come not destroyed in violent earthquake temporarily, still stand erect tall and straight, aim of the present invention that Here it is, is also the place that the peculiar glamour of giving is created in science of Mechanics and scientific and technological invention.Make that reinforcing bar mixing cement pillar is solid not to fall, there is more powerful strength and will make that high building is firmer solidly not to fall, there is powerful strength.Make high building firmer solid more powerful less than anti-seismic performance.This is determined by factors.Want to solve from starting with aspect two some root problems at this.For cylinder, concerning building body, one is exactly the problem of uniformity, integraty, globality.Popular saying makes Qi Liaojing exactly, works as one man and aims at simultaneously, jointly tackles from the strength that endangers body aspect, building, and unity strength makes toward a place, holds into a fist and could produce larger strength.Reinforcing bar is the main factor that produces holding capacity size, make reinforcing bar in cylinder, Lou Tizhong plays powerful effect, first to solve with concrete and have the more area of the long-pending combination of large contact surface, address this problem and will design the indented bars that superficial area is larger, make the concrete contact area of its root large, in conjunction with the large reinforcing bar of area; In addition, the peak power of blast earthquake shock cylinder, building body is from the strength in horizontal direction.We just should design the employing more powerful reinforcing bar that meets with stresses in the horizontal direction and aim at the direction of strength that blast earthquake attacks while impact and support earthquake-resistant impact force.It is larger which type of reinforcing bar has superficial area simultaneously, in horizontal direction, do there is there the function of larger holding capacity? cross efficient high-strength indented bars is best selection, and it has the technical characterictic of this two aspect simultaneously.We first analyze the technical characterictic of round thread reinforcing bar! If we are used in it in the concrete pillar in vertical and horizontal direction, it is all that equate, equally, balanced on any point of its any one plane in the horizontal direction, bearing intensity of force.This also means that its holding capacity has all been averagely allocated on each aspect of all directions, and the size of holding capacity is not have directively, collects not.Therefore, it is minimum with the identical ellipse in its cross section, ellipse rhombus, oblateness, triangle, square, rectangle, five rhombuses etc. at the subscriber intensity of force that bears upwards, also be perimeter of section minimum, if their sectional area equates, length also equates that their volume equates in other words, and it is also superficial area minimum.If the superficial area of these long body type objects all equates, round thread reinforcing bar is again of volume maximum.This that is to say that it is superficial area minimum that round thread reinforcement ratio is compared with other identical reinforcing bar of its cross section.Its intensity of force that bears is in a predetermined direction also minimum.Therefore the steel concrete that it does not meet modern architecture is built the technical requirements (superficial area is large) of engineering, is more not suitable for the technical requirements (function of high-intensity directionality holding capacity) of highrise building and anti-vibration residential.So just carrying out a mechanics processing mechanics to it processes? the superficial area that as far as possible increases it to be to increase the contact area of steel concrete, increases reinforcing bar and is combined the degree of solidifying with concrete; Increase simultaneously reinforcing bar in a predetermined direction bear intensity of force, to meet the technical requirements of high-rise quake-resistant safety house.Cross efficient high-strength indented bars is exactly our ideal chose.Fig. 1 is that a diameter is the comparison diagram of the cross section of the cross indented bars pilum that equates of 18mm round thread reinforcing bar base cylinder and cross section.The diameter of circle O is 18mm, radius OA=R=9mm, cross CHEF is combined by the semicircle D ' FC ' of the semicircle AGD+ of rectangle ABCD+ semicircle BHC+ rectangle A ' B ' ba+

diameter 2r=6mm.Calculate respectively the radius OA=R=9mm of the area and perimeter of round O and cross GHEF and their stressed distance, the ability meeting with stresses: ∵ circle O, the area S of

circle=91.672557682-56.5486677646=35.1238898036mm. the long 35.1238899174mm of girth of the cross section of the round thread reinforcing bar base cylinder that the cross indented bars pilum diameter group equating with round thread reinforcing bar cross section is 18mm, it has improved more than 62% than the transversal girth of round thread reinforcing bar base cylinder, so its superficial area has also just improved more than 62%.If theirs is equal in length, because their cross section is also equal, so their volume and weight also all equates.But, long 35.1238899174mm of the girth of the cross-sectional area of cross efficient high-strength indented bars pilum, it has also improved more than 62% than the girth of the round thread reinforcing bar base cylinder cross section of the 18mm with the equal diameter in its cross section, its superficial area has also just improved more than 62%, it and concrete contact area, also just improved more than 62% in conjunction with concrete area.The degree intensity that it is combined with concrete also will improve more than 62%.But this just calculates relatively they self technical characterictic directly perceived in order to simplify.In fact because the perimeter of section of cross indented bars pilum body is just just long a lot of than the perimeter of section with the equal round thread reinforcing bar base cylinder in its cross section, so the herringbone of its external surface, crescent, spiral rib also will be longer or more, the superficial area of screw thread will be larger.Reinforcing bar is combined the area solidifying with concrete will be larger, also will be firmer more solid in conjunction with what solidify.It is exactly strength problem that cross efficient high-strength indented bars also has more important more crucial problem, the problem of holding capacity size.The ability to bear that higher intensity is larger is only the basic of reinforcing bar.Because cross indented bars GHEF is made up of the semicircle BHC of semicircle AGD+ rectangle ABCD+ and semicircle A ' EB '+rectangle A ' B ' C ' D '+semicircle D ' FC '.The power that it bears also all distributes to that the object of each shape bears jointly.If the direction of active force faces the direction of axle FE, oblate A ' EB ' C ' FD will bear the strength of the overwhelming majority, and oblate DGABHC is bearing less strength; If the direction of active force faces the direction of axle GH, oblate DGABHC just will bear the strength of the overwhelming majority, and oblate A ' EB ' C ' FD ' just bears less strength.The energy holding capacity of accompanying drawing 1 in GH and FE direction equates.But the round thread reinforcing bar of the diameter group 18mm holding capacity in GH and FE direction is large much again for it.Strengthen the ability of having born in GH direction if want increase, we should increase stressed distance and the AD suitably increasing and the width of BC in GH direction, but the stressed distance of increase GH is more efficiently measure.If want to strengthen ability to bear in FE direction, just should increase the stressed distance in FE direction and suitably increase A ' B ' and C ' D ' width, but the stressed distance of increase FE is effective measures the most.Cross efficient high-strength indented bars is class series of products, comprises two identical oblate types, two oblate types of abnormal shape, and equal cross distance and the various cross indented bars of cross distance such as not.We have found such rule simultaneously: in the even long body of making in the same material of identical cross-section, pressurized (stressed) distance of object is larger, its holding capacity is just larger, pressurized (stressed) distance of object is less, its holding capacity is just less, and pressurized (stressed) distance of object is exactly from the starting point of object pressurized (stressed) to the distance between the end points of object pressurized (stressed).On object receiving force vertical plane, the superficial area in unit area is larger in other words, and the power that it bears is also just larger, otherwise still.Experimental results show that it is 1.5 times with the equal diameter in its cross section round thread reinforcing bar that is 18mm.Its maximum pressurized distance or maximum weighted distance are, GH=AB+2r=19.4933614313+2x3=25.4933614313mm, same FE=B, C '+2r=19.4933614313+6=25.4933614313mm, maximum pressurized (stressed) distance of cross indented bars is than large a lot of of pressurized (stressed) distance of the round thread reinforcing bar that is 18mm with the equal diameter in its cross section.Even can also increase, the maximum pressurized (stressed) of cross efficient high-strength indented bars distance can be more than 25.4933614313mm, and the pressurized (stressed) of the round thread reinforcing bar that diameter is 18mm distance just only has 18mm.Pressurized distance or the stressed distance of object refer to the vertical distance of object receiving force starting point to object receiving force terminal.The longitudinal axis namely from the stress point of object to the cross section perpendicular to object, if (direction of active force is vertical with cylinder, (pressurized distance) is exactly the diameter of cylinder cross section, is also cylindrical diameter), transverse axis is perpendicular to the longitudinal axis.Whatsoever the object of shape we make the longitudinal axis pass through the center line of its stress point cross section, make transverse axis also by its stress point plane perpendicular to longitudinal axis center line, Bing Shita center intersects at O point, and the size of major and minor axis ratio is determining the big or small directionality of it and same transverse cylinder holding capacity.That is to say that major axis is longer, minor axis is shorter, and its holding capacity on long axis direction is just larger, and it is than with its cross section and equal cylindrical holding capacity is just larger.We can sum up above with us equally about body surface, shape (form), the inner link between table, shape, body and the power of object is analyzed, explains and studied to the Changing Pattern of volume and holding capacity.If the constancy of volume of object (timing), the variation (change) of body surface area, will inevitably cause the variation (change) of body form, the variation (change) of body form (form), also will inevitably make the variation (change) of the mechanical structure of object.Also will inevitably make the holding capacity of object in certain direction greatly increase, the holding capacity in another direction can correspondingly reduce.The area of the cross circular section O of the round thread reinforcing bar base cylinder that the cross section GHFE of the cross efficient high-strength indented bars of Fig. 1 pilum body and diameter are 18mm equates.If their length is also equal, their volume and weight also all equates so.We carry out mechanics processing by the round thread reinforcing bar to same cross section, mechanics processing, has increased the superficial area of cross indented bars greatly, has changed the shape of round thread reinforcing bar, changed it mechanical structure, greatly increased its ability to bear in GH and FE direction in Fig. 1.If we want to continue to increase its holding capacity in FE direction, just can suitably reduce stressed distance in GH direction and the width of AD, BC, with the stressed distance in increase FE direction and the width of A ' B ', D ' C ', be the measure that the most effectively increases its holding capacity in FE direction and increase its length in FE direction.As shown in Figure 2.Also can suitably reduce OE length, increase the length of OF.Our final purpose mainly still wants to increase our ability to bear in a predetermined direction, increase the dynamics of reinforcing bar, increase the intensity of reinforcing bar, increase the supporting capacity of reinforcing bar, increase the superficial area of reinforcing bar, increase the degree that reinforcing bar is combined with concrete, increase cylinder, Liang Ti, Lou Ti, pontic, the intensity of concrete prefabricated element and concrete work and quality.Want to increase ability to bear and the intensity of each root reinforcing bar, increase the superficial area of reinforcing bar, prior art and traditional method are exactly the diameter that increases reinforcing bar, namely increase the section area of reinforcing bar or the radical of increase reinforcing bar.This is very uneconomic, is also very unscientific method.Our object is want on the basis that does not increase reinforcing bar cross section (diameter) exactly by changing the mechanical structure of object, the shape that changes object increases the perimeter of section of reinforcing bar, increase the superficial area of reinforcing bar, increase reinforcing bar supporting capacity in a predetermined direction, increase the intensity of reinforcing bar.Cross efficient high-strength indented bars is a kind of combined indented bars.It not only has the technical characterictic of the large and high-intensity directionality of superficial area, and it has and save material simultaneously, saves the technical characterictic of steel.It can save steel 5-35%.This reduces discharging current industry energy conservation, to national comprehensive regulation haze, purifies air, and reduces and pollutes, and also people's clear water blue sky, promotes national economy to continue the large good sharp technological means beyond doubt of development efficiently.It is a pioneering innovative technology with substantial economics and social benefit thus.It has just changed and has increased self superficial area and the function that has increased the holding capacity in certain direction, has solved " strength makes toward a place " and has just had larger strength.We are at anti-fall architectural this two large technical characterictic that has also utilized just it collapsing of antidetonation.Because the variation of the structure of object body causes the change of object mechanics function, the variation of its real object physique structure itself is exactly the variation on mechanical structure, and we study object and can not only it be regarded as the variation on body surface.The change of body is also reflecting the change of object essence, and this is the unification of shape and body.The mankind can not only advocate the object of aesthetic shape, have the powerful responsibility of antidetonation help and misread, buried U.S. of cross object and powerful mechanical structure and they.U.S. of their inherences is considerably beyond U.S. of aesthetic column type steel.Its mechanics function is for we build the high buildings and large mansions that do not fall of antidetonation more on architecture, and the house that Patient-trusted is lived in peace and firmer bridge tunnel water conservancy projects are laid a good foundation.The mankind only have by scientific and technical means could build the building not falling for firmer thousand, and it will start the new page on reinforced concrete architectural history, creates the mankind's splendidness.Though our cross efficient high-strength indented bars and the cutting point of using method research thereof are cylinders, scope and use value widely but it is also widely used, it is applicable to beam body very much, Lou Ti, bridge, building embodies the manufacture of watering top and prefabricated units.Some data that I quote as proof are the data of some analogies, not necessarily very definite (be make with clay, cement, timber, foamed plastics copy body to test to draw, individual result of study qualitatively), if used instead than the steel of thousands of up to ten thousand times of the high hundreds of of they intensity, believe that its multiple also can increase more.Also having a problem should be mentioned in that is exactly using method problem.The use of cross efficient high-strength indented bars is directive, and it is almost not have directively unlike round thread reinforcing bar, is almost the same in the holding capacity of each point of diameter surrounding.Holding capacity in its GH and FE direction in Fig. 1 of cross efficient high-strength indented bars is very large very large equating.Cross efficient high-strength indented bars in use, must make to need the direction of holding capacity maximum to face toward the direction of GH or FE, namely the direction of holding capacity maximum is faced toward to indented bars cross-sectional diameter apart from maximum direction, by the less direction of holding capacity facing to bar cross section apart from minimum direction, needs are born to the direction that less direction is intersected facing to FE axle and GH axle.If we are the two ends set level of the cross indented bars of a certain length, and make FE direction fall in horizontal direction, make GH direction be parallel to horizontal direction, add a very heavy weight to the mid point F place of the cross indented bars of this root, what F point bore is very heavy pressure, extruding force, what E point bore is drawing tension, this drawing tension is more much larger than extruding force obviously.A waddy or the reinforcing bar that fractures so we want to fracture, first disconnected is the following E point that you use point of force application, instead of the F of application point place point.Namely, taking stress point as the center of circle, the diameter taking stress point to this object is a track of radius picture arc.So also until you are converted into zero degree waddy or reinforcing bar, E point is disconnected, and still ins succession constantly in its application point F place, if you want to fracture it, you must act on E point place active force.This pressure, extruding force of bearing with regard to function of proof point place will liken little many of drawing tension with spot diameter end points to.Build building if build a house, the build a house building of founding a capital of China overwhelming majority is to sit in the north facing the south, and east-west, thing span is large, a face width, and stressed distance is large, and it is more impossible collapses in all directions or northwest southeastern direction and southwestern northeastward.Because this is two cornerwise directions of foundations body, stressed distance is wider more greatly.North and South direction span minimum, a face is narrow, and stressed distance is very little, and easily North and South direction is collapsed.If so when a pillar needs eight cross indented barss, the north in three close cylinders, the south in other three close square bodies, other two each one arranges near the east and west in square columns.Use if want to do cage of reinforcement in beam body, should make below more cross indented bars is placed in square beam body, can go easy above in square beam body, on the thing left and right directions in square beam body, use just more still less.The arrangement of arranging like this can produce larger effect.Cross efficient high-strength indented bars refers to the series of products of cross this class, and it comprises that various different cross section shapes and specification lateral road erect the indented bars of the cross efficient high-strength of the different cross shape of road composition.(comprise equilateral, different limit, different Bian Yi etc., what say is the series of products that have decussate texture).The size of cross efficient high-strength indented bars holding capacity is also directive, having holding capacity on four direction is all very large also equating, if the load of the cross efficient high-strength indented bars of accompanying drawing 1 in GH, HG, FE, EF direction is all very large also equating; Have in both direction holding capacity very large, holding capacity on another both direction is larger, if its holding capacity in the direction of FE and EF of the cross efficient high-strength indented bars of accompanying drawing 2 is maximum equating, its holding capacity upwards above GH and HG is larger equating; It is maximum also having holding capacity in one direction, and more maximum the taking second place of holding capacity in another direction, holding capacity on another both direction is more maximum more takes second place.The size of cross efficient high-strength indented bars holding capacity is directive thus, when use, can select the cross indented bars of dissimilar different size, use is the directionality principle that must follow it, to need the direction of holding capacity maximum facing to the direction of cross-sectional distance maximum, and will need the direction that holding capacity is less to face toward the less direction of cross-sectional distance.Arrange according to the needs of oneself, this be taking we anti-seismic concept as shift, cross efficient high-strength indented bars has good mechanical property and architecture performance, its superficial area is larger, what be combined with concrete is more firm firmer, high-intensity directionality holding capacity is larger, particularly in concrete cast engineering, supports mutually extruding, has made up cross barbed portion and has saved the deficiency that steel cause cross section to reduce.Can save the steel raw material of 5-35%.Have powerful antidetonation help responsibility, its is applicable to the technical requirements of architecture aspect very much, is particularly suitable for the demand of high-rise earthquake proof construction and safe house.There are very high economic worth and social value.Natural science applied object is found exactly and is studied natural rule and applies in practice these rules.If cross high efficiency and high strength indented bars and using method thereof can be in the whole nations, the whole world is applied, and will open up the beginning of building aseismicity house, will give the whole nation, and the people of the world erects the barrier of one safety temporarily in violent earthquake.Also can reduce discharging to industry energy conservation, reduce atmosphere pollution, national Synthetic haze, alleviates global warming and brings new hope.It feels concerned about people life property safety cross high efficiency and high strength indented bars, involves the interests of the state and the people, and relation country vital interests.There are great economic benefit and social benefit.Cross high efficiency and high strength indented bars is a kind of combined structure type indented bars.It is identical by three, and similar or different cuboid and four semicylinders combine.Comprise same widths thickness, different width dimensions, all kinds of various cross efficient high-strength indented bars that the semicylinder of shape and same radius different radii combines.

Specific implementation method
We have not only understood, and to have superficial area large, directionality operations is more powerful, the ellipse indented bars that quakeproof and quake-resistant performance is powerful, ellipse diamond pattern indented bars, oblate (ellipse flat) type indented bars, T font indented bars, also should understand cross efficient high-strength indented bars and using method thereof.Also that promotion are I-shaped from now on, H shape and two ellipse shape indented bars.There are these superficial areas larger, the holding capacity that directionality is more powerful is larger, and the scope of application is efficient high-strength indented bars widely, uses it as long as we follow its directionality principle, just can build the firmer building of cylinder not falling comes, at our general residence building of China, greatly mainly with sitting in the north facing the south, east-west in the majority, east-west direction span is large, seating surface is very wide, and stressed distance is large, is not easy east-west direction and collapses.In all directions or the southeast, northwest and on southwestern northeast or northeast southwestward more impossible collapsing because this is that on the diagonal of cuboid of stair, stressed distance is maximum.Span in North and South direction is little, and seating surface is narrow, and stressed distance is minimum, the therefore the weakest direction of Zhe Shi building body, and violent earthquake comes easily to collapse in North and South direction temporarily.So we just should use more or whole cross efficient high-strength indented barss facing to North and South direction.The pillar of such one one be just not easy in North and South direction big fall, add the solidating of lower ring beam and the integral cast-in-situ structure of roof roof, make bed rearrangement building house become a firmly firm entirety, such house high building just can not collapse naturally easily.So thinking, I to understand the mechanical structure mode of cross efficient high-strength indented bars, mainly to utilize its powerful mechanical technology feature, strengthen cylinder, Liang Ti, house, high building, mansion, and easy the to be big weak direction of easily collapsing of all buildings, aspect, position, link, utilize the powerful effect of cross efficient high-strength indented bars directionality, powerful holding capacity function, strengthen cylinder, Liang Ti, the ability to bear of building body and all concrete structures, strengthen cylinder, Liang Ti, the ability to bear of building body and all concrete structures and firmness degree, the powerful impact force that opposing earthquake is rocked.Embodiment: 12 concrete pillars of the minimum needs of new house of building five rooms.If every pillar needs eight cross efficient high-strength indented barss, every cross efficient high-strength indented bars increases by 0.5 times than the holding capacity of following the equal round thread reinforcing bar in its cross section in North and South direction, such pillar is just equivalent to 1.5 with common pillar so, and 12 such pillars just can push up nearly 20 common pillars.12 such pillars need nearly hundred cross efficient high-strength indented barss.Every reinforcing bar all will combine firmly with concrete, makes the direction of these nearly hundred reinforcing bar holding capacity maximums all face toward the direction of this north and south and Bei Nan, and their common strength producing is very powerful, huge.This has just increased house, the building ability in North and South direction or the resistance violent earthquake upwards of south, north greatly.Our 12 pillars just can have been given play to 20, the even strength of tens pillars and effect.This is also the spitting image of there being a stifled danger wall, and you are in order to allow it not fall, and you just can push up an inclined strut, and you want to allow it more solid again, and you just can push up upper several inclined struts more, and you want to allow it in violent earthquake, not fall, and you must prop up it by many topmasts post.Our cross efficient high-strength indented bars is the key that solves the problem of few topmast post, and we are the functions that replaced many topmasts post with the cross indented bars of the high efficiency large function of high strength.Is this reason in fact or the same? reason communicates.Natural science applied object is find and study natural law and apply in practice these laws.We not only will learn away the road that forefathers and others pass by practice, and we more will learn to start new road, make descendant more convenient for walking.What in a word, the mankind can be not eternal in face of violent earthquake feels simply helpless.We will build the building of antidetonation more, the high buildings and large mansions that do not fall for thousand by scientific and technological means, the method for science.We are again reluctant to have seen the miserable scene of picture Tangshan Earthquake, Xingtai violent earthquake, Wenchuan violent earthquake.I am willing to allow common people's the security of the lives and property not suffer a loss.The people are lived and worked in peace and contentment, as secure as Mount Taishan.The series of products of cross efficient high-strength indented bars and using method thereof, will open the beginning shockproof, earthquake proof construction, is also that exploration is shockproof, the new way of antidetonation.It will start the new page in architecture history.If technique can be in the whole nation, whole world extensive use erects the barrier of one safety will to the people of the world temporarily in violent earthquake.
