Abstract
The utility model discloses a reinforced concrete column with local buckling constraint of longitudinal bars. The reinforced concrete column comprises a concrete column and a steel bar framework structure wrapped in the concrete column, wherein the steel bar framework structure comprises a plurality of longitudinal bars which are vertically arranged and stirrups which are arranged at intervals along the longitudinal direction and horizontally arranged around the longitudinal bars, and the reinforced concrete column is characterized in that a sleeve is further sheathed at the end part of each longitudinal bar, filling material is filled between the inner walls of the sleeves and the longitudinal bars, and the stirrups at the sleeves are connected and arranged on the outer sides of the sleeves. The sleeves are steel pipes. The filling material is mixed mortar material. The reinforced concrete column disclosed by the utility model has the advantages of simple structure and excellent anti-seismic effects, the anti-unstability capability of the reinforced concrete column is greatly enhanced and the reinforced concrete column can withstand greater earthquakes, therefore, the reinforced concrete column is particularly suitable for being popularized and applied in areas with high-intensity earthquakes.
Description
Technical field
The utility model is a kind of building reinforced concrete rod structure, relates in particular to a kind of reinforced concrete post of vertical muscle cripling constraint.
Background technology
In the modern architecture, generally adopt reinforced concrete post to support as building foundation.Existing reinforced concrete column, be generally following structure, comprise the many vertical muscle that vertically arrange, vertical muscle is around being arranged as rectangle or circle, the vertical muscle outside is provided with some rectangles or circular stirrup around vertical muscle, and stirrup is horizontally disposed with and longitudinally is intervally arranged, and vertical muscle constitutes the steel bar framework structure with stirrup, be that basic concreting forms concrete column with the steel bar framework structure then, concrete column with the steel bar framework encapsulated by structures in it.
This existing reinforced concrete column braced structures; there is the possibility that is subjected to the flexing unstable failure in frame construction post vertical muscle in high earthquake intensity area in China's earthquake; in earthquake takes place; post two ends moment of flexure and shearing are very big, and concrete cover can seriously ftracture even peel off, and stirrup is thrown off probably then; under than the high axial compression ratio situation; the flexing unstable failure takes place in vertical influential point of tendons, causes column intensity and rigidity moment to be reduced, and causes structure generation heavy damage even collapses.
So above-mentioned existing reinforced concrete column structure exists the defective of poor seismic behavior, easy flexing unstability when earthquake takes place and collapsing.
In order to solve this defective, the mode that generally can take to reduce stirrup spacing and increase lacing wire, but can increase certain cost like this, and not deal with problems from principle simultaneously, its anti seismic efficiency is still relatively poor.In the prior art, also exist part to be used for improving the technology that building supports shock resistance, for example application number 200910195822.9 disclosed a kind of vertical reinforced concrete component-connection node of buckling-restrained brace, and number of patent application 201010292941.9 disclosed a kind of building energy conservations and the buckling-restrained support of structure-integrated wallboard formula.In these technology, all be to have adopted a kind of buckling-restrained unit to be set in the steel bar framework, can improve the buckling-restrained effect of steel bar framework to a certain extent.But still there are complex structure and a relatively poor defective of anti seismic efficiency.
The utility model content
At the problems referred to above and deficiency, technical problem to be solved in the utility model is: how to provide a kind of simple in structure, the reinforced concrete post of the vertical muscle cripling constraint that anti seismic efficiency is good.
In order to address the above problem, the utility model has adopted following technical scheme.
A kind of reinforced concrete post of vertical muscle cripling constraint, comprise concrete column and be wrapped in the interior steel bar framework structure of concrete column, described steel bar framework structure comprises the many vertical muscle that vertically arrange and longitudinally is intervally arranged and centers on indulges the horizontally disposed stirrup of muscle, it is characterized in that, the end position of described every vertical muscle also is arranged with sleeve, be filled with packing material in the sleeve and between the vertical muscle, the stirrup connection at its middle sleeve place is arranged in the sleeve outside.
In the utility model, the sheathed sleeve in end at vertical muscle arranges packing material in the sleeve, and sleeve is with packing material, for vertical muscle end provides a great buckling-restrained effect like this.Because vertical muscle end position is plastic hinge region, when being in earthquake, this is the position of easy bending deformation, provided herein after the buckling-restrained effect of certain intensity, just greatly improved the anti-flexing unstability ability of this concrete column, can bear bigger geological process.This structure of while has simple in structure, the advantage of easy construction.
As optimization, described sleeve is steel pipe.Steel pipe has the high advantage of self hardness intensity, can avoid sleeve self destroyed and lost efficacy.Employing was weldingly connected when simultaneously steel pipe was convenient to be connected with stirrup.
As optimization, described packing material is the composite mortar material.Has low price, advantage such as filling effect is good.
In sum, the utlity model has simple in structure, the advantage that anti seismic efficiency is good, it has greatly strengthened the anti-unstability ability of reinforced concrete post, can enough bear more violent earthquake load, is particularly suitable in earthquake high earthquake intensity area and applies.

Fig. 1 is the structural representation of independent steel bar framework in the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
This specific embodiment is, a kind of reinforced concrete post of vertical muscle cripling constraint, comprise concrete column and be wrapped in the interior steel bar framework structure of concrete column, described steel bar framework structure as shown in Figure 1, comprise the many vertical muscle 1 that vertically arrange and longitudinally be intervally arranged and center on and indulge the horizontally disposed stirrup 2 of muscle, the end position of described every vertical muscle 1 also is arranged with sleeve 3, is filled with packing material in the sleeve 3 and between the vertical muscle 1, and stirrup 2 connections at its middle sleeve 3 places are arranged in sleeve 3 outsides.In this specific embodiment, described sleeve 3 is steel pipe.Described packing material (not shown) is the composite mortar material.Number in the figure 4 is bases, bottom.
The above-mentioned specific embodiment; should be considered as preferred exemplary of the present utility model rather than restriction, when specifically implementing, described sleeve can also adopt the sleeve of other materials; described packing material can also be taked the filler of other materials or prescription, should be considered as still falling into protection domain of the present utility model.
