Description
Technical field
The utility model relates to engineering component technical field more particularly to a kind of buckling-resistant support structure components.
Background technique
With a large amount of construction of China's infrastructure and high speed development, the structures such as super high-rise building, Loads of Long-span Bridges are in China
Area of providing fortification against earthquakes constantly is emerged in large numbers, and since China is one of the country that earthquake in the world most takes place frequently, almost has a destruction every year
Property earthquake occur, huge harm, super high-rise building and Loads of Long-span Bridges knot will be come to the safety belt of life property and infrastructure
Structure etc. carries critical effect in social and economic development, and curvature-prevention support component is a kind of with energy-dissipating and shock-absorbing effect
Lateral resistant member, be generally made of kernel core material component and peripheral constraint component two parts, the section of component is united along length
One size, and be uniformly distributed using same material, this structure causes supporting member and concentrates in intermediate stress easy to form,
Finally it is easy to cause outer deformation excessive and function timeliness, to meet the needs of inner core component extruding, inner core component is longer than periphery about
There is rigidity jumping phenomenon, and the stress of inner core component total cross-section surrender at overhanging section of inner core component in beam component, integrated member
State aggravate its outer figure stress burden, due to this stiffness of structural member be reduced after surrender it is more, its own connection bearing capacity with
And be affected to component holistic resistant behavior, extended segment outside the end of inner core component is probably because inner core component
It surrenders and is destroyed prior to inner core component.
Summary of the invention
The utility model can satisfy super-high building structure or longspan structure to solve the above problems, providing one kind
Demand, the overhanging stronger anti-buckling support steel structure component of surrender section intensity.
Technical solution adopted in the utility model:
A kind of buckling-resistant support structure component, including inner core component and angle steel, inner core component is in cross, outside four angle steel
For packet on inner core component, the apex angle of angle steel concentrates on the cross infall of inner core component, does not surround kernel structure on the side wall of angle steel
The outer edge of part opens up multiple threaded holes, and the threaded hole that adjacent angle steel side wall is opened is corresponding, and adjacent angle steel is between corresponding threaded hole
Sandwiched cushion block passes through cushion block by bolt and connects adjacent angle steel side wall, and the two ends of inner core component are longer than the both ends of angle steel
Capitiform carries out inner core component by inclined-plane to extend out processing formation strengthening segment, angle at overhanging surrender section, the both ends of overhanging surrender section
The outer envelope strong concrete of steel, every block of angle steel is outer axially through being equipped with prestressed cable in strong concrete, high-strength
Spend concrete outsourcing outer steel pipe.
The outer contoured shape of the strong concrete is round or rectangle.
The cross-sectional width of the strengthening segment is not more than the widest part of strong concrete.
The utility model has the beneficial effects that the utility model angle-bar joint using the cushion block that is provided separately, reduce by
In the overall collapse that stress is concentrated and is occurred, high bearing capacity of the buckling restrained brace in large deformation is improved, is increased
Applicability and whole stability of the component under big shake effect, while inner core component two ends form strengthening segment, guarantee section
Point is not destroyed prior to the surrender of inner core component, and prestressed cable is arranged in strong concrete, effectively prevent concrete in tension
Cracking.

Specific embodiment
A kind of buckling-resistant support structure component, including inner core component 9 and angle steel 4, inner core component 9 are in cross, four angles
For 4 outsourcing of steel on inner core component 9, the apex angle of angle steel 4 concentrates on the cross infall of inner core component 9, does not wrap on the side wall of angle steel 4
The outer edge for enclosing inner core component 9 opens up multiple threaded holes, and the threaded hole that 4 side wall of adjacent angle steel is opened is corresponding, and adjacent angle steel 4 is right
Sandwiched cushion block 5 between threaded hole is answered, cushion block 5 is passed through by bolt 6 and connects adjacent 4 side wall of angle steel, the two ends of inner core component 9
The two ends for being longer than angle steel 4 form overhanging surrender section 1, and the both ends of overhanging surrender section 1 carry out inner core component 9 by inclined-plane 7 outer
Expand processing and forms strengthening segment 8, the outer envelope strong concrete 2 of angle steel 4, every piece of 4 outer axis of angle steel in strong concrete 2
To through equipped with prestressed cable 3,2 outsourcing outer steel pipe 10 of strong concrete.
The outer contoured shape of the strong concrete 2 is round or rectangle.
The cross-sectional width of the strengthening segment 8 is not more than the widest part of strong concrete 2.
Design angle steel 4 and 10 Two-layer constraint power steel construction of outer steel pipe are reduced using the cushion block 5 of split due to stress
The overall collapse concentrated and occurred, improves high bearing capacity of the buckling restrained brace in large deformation, mixed in high intensity
Arrangement prestress rope 3 in solidifying soil 2, provides prestressing force to strong concrete 2, can effectively prevent strong concrete 2 by
It pulls open and splits.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
