Description

A kind of anti-buckling support of all steel of more kernels

Technical field

The utility model relates to a kind of anti-buckling supports of all steel of more kernels, belong to technical field of structural engineering.

Background technique

It is anti-that anti-buckling support is widely used in high building structure, space structure, science of bridge building Aseismic Design and engineering During shake is reinforced.Anti-buckling support is made of inner core component and restraining tube system, and inner core component bears axial compressive force, peripheral member The lateral displacement for constraining inner core component prevents kernel from buckling occurs.Under normal operating condition and small shake, anti-buckling support is played Generic central supporting role, inner core component keep elasticity, provide the anti-side rigidity of building；Under middle shake and big shake, anti-buckling branch The inner core component of support, which takes the lead in entering, to be surrendered and by the energy of its tension and compression hysteresis dissipation Seismic input repeatedly.

Anti-buckling support can be divided into the multiple types such as whole restricted type, assembled, shuttle shape, kernel separate type according to form Type, and inner core component is mostly using having linear type, the low-yield of work shape or star section, high ductility steel, it can be The effect of energy consumption is given full play in seismic process.It is mainly constrained using concrete filled steel tube in engineering construction at present and kernel is a word The anti-buckling support of shape or star section.

Demand with engineering construction to the anti-buckling support of extra high load bearing capacity is more more and more urgent, and common steel pipe is mixed in engineering Solidifying soil constraint and the anti-buckling support of single kernel have the disadvantage in that the time required to the casting of (1) concrete and strength development compared with It is long, and there are the troubles of wet construction, it is difficult to form efficiently production and intense industrialization；(2) single kernel high-bearing capacity is anti-buckling Support will lead to the increase of kernel section panel thickness or kernel sectional dimension increases, and big thickness plate materials are difficult, and its material Property ductile deformation is less able, thus limits its application in the anti-buckling support of high-bearing capacity；(3) using single kernel The anti-buckling support of concrete filled steel tube restricted type certainly will lead to biggish restraining tube sectional dimension, increase the weight of support, instead Biggish geological process, effective control of unfavorable geological process can be caused due to biggish self weight；(4) compared to clean steel restricted type Anti-buckling support, quality and sectional dimension are all larger, and transportation cost is larger after the molding of factory's overall processing, while larger section Face size will lead to processing technology complexity, and then increase project cost.

Utility model content

To solve the above problems, being built the utility model proposes a kind of anti-buckling support of all steel of more kernels in realization engineering If high-bearing capacity can choose the inner core component of relatively small thickness while require, guarantee the high ductility of inner core component；Using complete Steel member can all make in factory, and easily controllable dimensional accuracy and welding quality avoid the inconvenience of concrete wet construction；? End plate welded sleeve, compensation kernel go out the rigidity formed after peripheral constraint component and fall sharply.

A kind of anti-buckling support of all steel of more kernels adds containing inner core component 1, peripheral constraint component 2, end plate 3, sleeve 4 Strength rib 5, which is characterized in that inner core component 1 of the anti-buckling support comprising peripheral constraint component 2 and package inside it, institute Inner core component 1 is stated to be made of four seamless steel pipes 1-1,1-2,1-3,1-4；Described 2 one end of peripheral constraint component and the end plate 3 Circumferentially disposed ribbed stiffener 5 is arranged in welding around the end plate 3, and the other end and the end plate 3 keep certain gap, and Sleeve 4 is set on the outside of the peripheral constraint component 2, the sleeve 4 with peripheral constraint component 2 in axially opposing sliding, and with End plate 3 welds, and ribbed stiffener is arranged on the outside of sleeve.

In above-mentioned anti-buckling support, the peripheral constraint component 2 is using larger-diameter welding square steel tube and welding circle Steel pipe, material yield strength use Q345 and the above grade of steel.

In above-mentioned anti-buckling support, the end plate 3 is rectangle plain plate.

In above-mentioned anti-buckling support, the sleeve 4 is shaping drum or square sleeve.

The utility model proposes this novel more anti-buckling supports of kernel all steel, have the advantage that (1) using more The anti-buckling support of kernel, the high-bearing capacity required in engineering construction easy to accomplish, while can guarantee the small thickness of Core Choice Or small bore component, materials are convenient, and ductility quality can also be guaranteed, and be content with very little requirement of the inner nuclear material to ductility；(2) Using all steel component, can all be made in factory, scantling precision and welding quality are easily controllable, whole industrialized production journey Degree and component producing efficiency are high, and in-site installation is convenient and saves the duration, and it is inconvenient to avoid concrete wet construction bring；(3) it adopts With all steel component total quality is light, sectional dimension is small, processing technology is simpler, while being conducive to the transport after factory process And installation, reduce project cost.
