Technical field
The utility model relates to a kind of concrete foundation stanchion, especially a kind of have cushioning effect, crashproof effective, can be widely used in carry out in the engineering structures field strengthening reconstruction and newly-built, as the concrete with composite material sheath of pier stud in the big bridge of the magnitude of traffic flow, all kinds of civilian construction, ocean and coastal waters, the underground engineering structure and supporting member, specifically a kind of composite material lattice sandwich tube restriction concrete foot stall with buffering energy-absorbing function.
Background technology
At present, flourish along with transportation and economic construction, more and more across the large bridge of Jiang Hai, urban interchange, viaduct also can be found everywhere, and make bump bridge pier accident sharply increase.Although be not each time collision accident all lead to bridge and ruin the great tragedy that the people dies; but the application life of bridge; the reduction of safety and shock resistance is sure really; cause thus and suspend traffic; the economic loss of repairing circuit is also serious year by year. at this situation; the traffic department of many countries all requires some important large bridge bridge piers are protected. for this reason; external scholar has taken the lead in carrying out relevant research; the bridge collision theory has been proposed; and having designed some bridge pier protective equipments. China mainly concentrates on and uses for reference and with reference to the foreign study achievement; carry out the design and the application of the anticollision device, collision-prevention device of example bridge; its achievement is quoted by the part standard, but the China that is installed in of research work that pier anticollision hits and anticollision device, collision-prevention device still fails to cause enough attention.In addition, existing anticollision device, collision-prevention device geometric scale is bigger than normal, and it is attractive in appearance that profile is owed, and can not satisfy the requirement of Modern Traffic to anticollision device of pier.
In addition, though steel concrete and encased structures have advantages such as stress performance is good, cost is low.But when being applied to structure such as bridge, hydro-structure, ocean and coastal waters and other and having the environment of aggressivity or exposure property, strong corrosive medium and heavily stressed acting in conjunction make reinforcing bar or steel pipe get rusty very soon, rupture, and finally cause structural deterioration.
Summary of the invention
The purpose of this utility model is that existing passive concrete pier stud crashworthiness is relatively poor, the problem fragile, that the life-span is short, design can be used for strengthening reconstruction and new construction, be specially adapted to as pier stud and supporting member in the big bridge of the magnitude of traffic flow, all kinds of civilian construction, ocean and coastal waters, the underground engineering structure, in the hope of obtaining good structure tension performance, crashworthiness, improve the pier stud durability, be convenient to transport composite material lattice sandwich tube restriction concrete foot stall with buffering energy-absorbing function with installation.
The technical solution of the utility model is:
A kind of composite material lattice sandwich tube restriction concrete foot stall with buffering energy-absorbing function, it is characterized in that it is made up of pier stud cover 7 and the concrete inner core 5 that is cast in the pier stud cover 7, be embedded with the reinforcing bars 4 that play the increase tensile strength that axially are provided with along pier stud cover 7 in the concrete inner core 5; Described pier stud cover 7 is by managing 3 in composite material outer tube 1, the composite material, connecting the lattice 6 of pipe 3 in composite material outer tube 1 and the composite material and the padded coaming 2 that is filled in the space that is surrounded by pipe 3 and lattice 6 in composite material outer tube 1, the composite material is formed.
The horizontal sextant angle of described fiber is 45 °～55 °.
Described padded coaming 2 is polyurethane, light wood, foamed aluminium or the artificial caoutchouc with damping, vibration isolation effect.
Described concrete inner core 5 is for solid construction or be provided with a hollow-core construction of overlapping 7 axis direction through holes 8 along pier stud at least.
Described through hole 8 is circle, ellipse, polygon or their combination.
The profile of described pier stud cover 7 is polygon, circle, ellipse or waist shape or their combination.
The beneficial effects of the utility model:
1. the utility model composite material lattice sandwich of layers of having utilized concrete pier stud outer wrapping; padded coaming in the sandwich of layers relies on the ability of the self-recovery elastic deformation of structure or material to transform and discharges Impact energy; can prolong collision time; thereby reduce impact, reach the effect of protection car and boat and bridge.
2. composite material tube adopts two-way assorted fibre weaving pultrusion, has made full use of the good tensile property of fiber, and the hot strength of product is higher than common iron.
3. the utility model examining tensile behavior that composite material tube is superior combines with concrete compressive property, composite material tube is under the complex stress condition concrete to concrete effect of contraction on the one hand, thereby concrete intensity is improved, and plasticity and toughness properties are greatly improved; Concrete on the other hand existence can be avoided or delay composite material tube local failure takes place prematurely, thereby can guarantee giving full play to of its material property.A large amount of maintenance, rehabilitation expense are saved in the generation of problems such as this combining structure can replace or part replaces traditional reinforcing bar enhancing, and the structure of fundamentally avoiding or lower the corrosion of invar muscle to cause is aging, make structure have favorable durability;
The utility model when construction with composite material tube as the permanent template of building its core concrete,, saved the comprehensive cost of engineering, making pre-formedly becomes possibility with batch production production.
