Abstract

The utility model discloses an inner base plate stiffener type concrete-filled steel tube column base, comprising a base arranged at the bottom end of a concrete-filled steel tube column, wherein the steel tube column is welded with the base; a stiffening plate is welded on the base as an inner base plate stiffener at the inner wall of the steel tube, and upper and lower top ring plates are arranged. By adopting the inner base plate stiffener type concrete-filled steel tube column base, the elastic rigidity and the bearing capacity of a concrete-filled steel tube column base joint can be increased, local damage to the column bottom is prevented, the column bottom is even in stress, the thickness of the bottom plate can be significantly reduced, and the mechanical property of the column base is obviously improved. The inner base plate stiffener type concrete-filled steel tube column base is simple in structure, easy to process and fabricate, convenient to construct and operate, and strong in building applicability.

Description

Boots beam type steel tube concrete column feet in a kind of
Technical field
The utility model relates to a kind of huge steel tube concrete column feet, the particularly a kind of huge steel tube concrete column feet of interior boots beam as the plate of putting more energy into that adopt, and this suspension column is applicable to any building structure that has requirements for fortification against earthquake.
Background technology
Along with the development of modern economy technology, the height of building constantly develops in depth.Encased structures is a kind of new structure growing up on the basis of spiral reinforcement reinforced concrete structure, it takes full advantage of the architectural characteristic of steel pipe and two kinds of different materials of concrete, there is excellent mechanical property, building applicability, economy and workability easily, adapt to modern project structure to large span, towering, heavy duty development and bear the requirement of severe environmental conditions, in modern high-rise, Super High structure, having obtained application more and more widely.
Suspension column is encased structures middle and upper part agent structure and the important node that basis is connected, and is the principal element that determines its bearing capacity.In structure, play an important role, it can effectively be fixed shaft and axle power, the bending and shearing of post lower end are passed to basis, guarantee superstructure with basis reliable connection.The stability of the switching performance of foot joint and structure and member is closely related, and structural internal force and displacement are produced to material impact.Basis, steel core concrete column bottom is reinforced concrete structure, from having to nothing, causes structural discontinuously at suspension column part concrete filled steel tube, if dealt with improperly, is easy to destroy, thereby affects integrally-built safety.Therefore, suspension column is one of important component part of encased structures.
At present, conventional steel tube concrete column feet form has three kinds of exposed, outer-enwraped type and flush types etc.Exposed suspension column is made up of base plate, boots beam (stiffening rib), crab-bolt and crab-bolt support bracket etc.; Outer-enwraped type suspension column wraps up formation by suspension column with steel concrete; Flush type suspension column is first pillar to be fixed in reinforced concrete foundation or grade beam on request, and then concreting, directly imbeds suspension column in reinforced concrete foundation or grade beam.For exposed suspension column, boots beam can obviously increase the elastic stiffness of foot joint, improves its anti-bending bearing capacity.But for huge steel tube concrete column feet, if adopt traditional exposed suspension column form, be placed in steel pipe outside by boots beam, need to adopt the suspension column base plate of very large thickness, and the discontinuity on suspension column base plate and basis, bottom, thereby affect the safety and reliability of structure.In addition, " seismic design provision in building code " (GB50011-2010) improved post root bending moment internal force and adjusted coefficient, makes to use simple exposed suspension column be difficult to or cannot meet the requirement of strong post root in huge encased structures.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, and a kind of huge steel tube concrete column feet of interior boots beam as the plate of putting more energy into that adopt is provided.Compared with suspension column without boots beam, foot joint elastic stiffness and bearing capacity that boots beam (stiffening rib) is set obviously increase, and along with the increase of stiffening rib thickness, the beaming resistance limit bearing capacity of foot joint also can improve.This suspension column, by boots beam is placed on to steel duct, has reached the above-mentioned object of putting more energy into, and has saved architectural space, can be combined with outer-enwraped type or flush type foot joint, in the hope of obtaining excellent mechanical property and economic indicator.In addition, interior boots beam can also significantly reduce base plate thickness, makes suspension column bottom stressed evenly.This suspension column is applicable to Large-diameter Steel pipe concrete column.
In order to achieve the above object, the utility model adopts following technical scheme to be achieved:
Boots beam type steel tube concrete column feet in a kind of, comprise steel pipe column, below steel pipe column, be provided with annular roof plate, be provided with circular bottom plate apart from annular roof plate certain distance along steel pipe column tube wall, between annular roof plate and circular bottom plate, be vertically installed with multiple stiffeners along steel pipe column tube wall circumference symmetry, stiffener is inclined-plane near the face of steel pipe column central axis, and the inclined-plane of stiffener reduces from top to bottom gradually far from the distance of steel pipe column central axis, forms boot last structure.Have concrete in the inner pouring of steel pipe column, interior boots beam base is connected with foundation by crab-bolt.
The utility model also comprises following other technologies feature:
On annular roof plate and circular bottom plate plate face, be evenly provided with anchor hole, anchor hole and crab-bolt match.
Owing to adopting such scheme, the utility model has the following advantages compared with conventional steel concrete suspension column:
1, by setting up upper strata top board, upper strata top board, lower floor's base plate, steel pipe and interior boots plate are connected as a single entity, enlarge markedly foot joint rigidity and bearing capacity.
2, adopt interior boots plate as the plate of putting more energy into, make column base plate stressed even, can significantly reduce base plate thickness, obviously improve the mechanical property of post coxopodite point.
3, by built-in boots plate, do not take space outerpace, can be combined with other forms of suspension column.
