Technical background
As a kind of novel lateral resistant member of many high-rise steel structure, anti-buckling energy-consumption be supported on Japanese slope shake celestially with the mountain range earthquake of U.S. north after be widely used in newly-built structure and the old house reinforcing.The great advantage that anti-buckling energy-consumption supports is its double lateral resistant member and power consumption dual-use function done, being supported under the pressure effect with cross hang or off-centre in the existing steel frame effectively energy dissipating comparison after the flexing takes place, is the product of lateral resisting architectural study and scientific and technological progress in the seismic design.
Little, in and under the big shake effect, anti-buckling energy-consumption supports the effect not only can play lateral resistant member all the time, and is entering the ability that surrender consumes the earthquake input under big shake effect.This effect comes from the effect of contraction that kernel steel plate that anti-flexing supports is subjected to peripheral cell, flexing can not take place when big shake effect pressurized, and nuclear cross section surrender in showing as.Supporting member shows essentially identical hysteresis performance under the tension and compression course under cyclic loading like this, and hysteresis loop is very full, is catabiotic excellent member.
But the anti-buckling energy-consumption supporting member that generally adopts on engineering is made up of peripheral steel pipe, built-in concrete and kernel steel plate at present, and its shortcoming is that dimensional accuracy is controlled height when making, cost of manufacture is high.Will leave certain clearance between particularly built-in concrete and the kernel steel plate, very strictness of the precision in its gap control causes construction extremely difficult during concreting.
The utility model proposes a kind of brand-new anti-buckling energy-consumption and support, its whole parts are made up of the steel member fully, are full prefabricated members.This anti-buckling energy-consumption supports not only can play the lateral resisting effect, and can effectively protect agent structure by the surrender earthquake energy of embedded steel plate when big shake.
The utility model content
The all-steel buckling-preventing energy-consuming that the utility model proposes supports, and its purpose is to provide a kind of complete fabricated supporting member, and the lateral resisting effect is provided, and effectively power consumption under big shake effect, and easy construction, can save cost.
A kind of all-steel buckling-preventing energy-consuming that the utility model proposes supports, and it is characterized in that, described support is made up of with kernel " " font steel plate 5 four hot-rolled groove-shape shaped steel 1, hot-rolled groove-shape shaped steel 2, hot-rolled groove-shape shaped steel 3, hot-rolled groove-shape shaped steel 4; Described four hot-rolled groove-shape shaped steel 1, hot-rolled groove-shape shaped steel 2, hot-rolled groove-shape shaped steel 3, hot-rolled groove-shape shaped steel 4 are connected to form peripheral constraint component by high-strength bolt 6; 5 of described peripheral constraint component and kernel " one " font steel plates leave certain space, and scribble non-cohesive material; At welding kernel steel plate end, described kernel " " font steel plate 5 ends stiffener 10, form the cross node; At frame joint is that frame joint junction plate 7 is stretched out at cross node place, and lead frame node junction plate stiffener 8 also forms the cross node on frame joint junction plate 7; By described four C shape shaped steel 9, connecting frame node junction plate 7 and kernel " " font steel plate 5 adopt high-strength bolt 11 to connect; The described span centre that supports at energy consuming is provided with and supports span centre fastener 14, to prevent the slip of kernel " " font steel plate 5.
A kind of all-steel buckling-preventing energy-consuming that the utility model proposes supports, and can provide good lateral resisting effect for many high-rise steel structure, and under big shake effect, can reach the total cross-section surrender, thus effectively power consumption.In addition, this anti-buckling energy-consumption is supported for full prefabricated member, is easy to processing and installs, and can effectively reduce structural cost, is that a kind of anti-buckling energy-consumption of performance brilliance supports.
