Description
Technical field
The utility model relates to a kind of civil engineering structure, specifically is a kind of bean column node core space structure of different concrete kinds.
Background technology
In order to satisfy the needs of building energy-saving insulation, the floor plate at building branch family and relevant structural element such as the crossbeam lightweight aggregate structural concretes with heat-preserving building thermal property (being low thermal conductivity) that adopt replace ordinary concrete more.Described lightweight aggregate structural concrete is exactly to replace stone coarse aggregate in traditional ordinary concrete with light coarse aggregate (haydite), forms quality and is lighter than ordinary concrete, possesses the bearing load ability and possesses the haydite concrete of certain heat preservation and energy conservation effects.This lightweight aggregate structural concrete can reach the Strength of Common level aspect compressive strength, but since its modulus of elasticity lower, so non-deformability a little less than.The column of building then adopts compressive strength height, ordinary concrete that non-deformability is strong.The position that in the industry column is combined with crossbeam is called the bean column node core space.
The bean column node core space structure of the different concrete kinds of prior art is as follows: it comprises two crossbeams of being poured into a mould by the lightweight aggregate structural concrete of (end absolute altitude that is crossbeam is identical) by the column of ordinary concrete cast and on being positioned at same absolute altitude, above-mentioned three (solid) intersects vertically, be provided with the some crossbeam steel bar stresses parallel in the described crossbeam with crossbeam, every crossbeam also is provided with crossbeam stirrup some and the vertical colligation of every crossbeam steel bar stress, be provided with the column steel bar stress parallel with column in the described column, described column is in overlapping inside of three and also be provided with column stirrup with the vertical colligation of column steel bar stress up and down; Because the subscript higher position of the overlapping portion of three is the end absolute altitude (promptly the end absolute altitude with crossbeam is identical) of crossbeam, when pouring into a mould the concrete of the overlapping portion of three, can only pour into a mould simultaneously with the concrete of crossbeam, and can't separately pour into a mould concrete with the crossbeam different cultivars, so the concrete of the overlapping portion of three belongs to the lightweight aggregate structural concrete identical with crossbeam.
There is following defective in the bean column node core space of the different concrete kinds of prior art: because so that this part of column is out of shape easily, there is potential safety hazard in the non-deformability deficiency of the lightweight aggregate structural concrete of the overlapping portion of three under the load effect.
The utility model content
The technical problems to be solved in the utility model is, provides a kind of and can strengthen non-deformability, stops the bean column node core space structure of the different concrete kinds of potential safety hazard.
Technical solution of the present utility model is, a kind of bean column node core space structure with different concrete kinds of following structure is provided, it comprises a column and two crossbeams by the cast of lightweight aggregate structural concrete that are positioned on the same absolute altitude by the ordinary concrete cast, above-mentioned three intersects vertically, the overlapping portion of described three is by the lightweight aggregate structural concrete cast identical with crossbeam, be provided with the some crossbeam steel bar stresses parallel in the described crossbeam with crossbeam, every crossbeam also is provided with crossbeam stirrup some and the vertical colligation of every crossbeam steel bar stress, be provided with the column steel bar stress parallel in the described column with column, described column is in overlapping inside of three and also be provided with column stirrup with the vertical colligation of column steel bar stress up and down, be provided with the additional bar cage in overlapping of the described three, described additional bar cage comprise at least four vertical additional steel bar stresses with the additional stirrup of the vertical colligation of additional steel bar stress, described additional stirrup is positioned at the altitude range of the overlapping portion of three.
After adopting above structure, the bean column node core space structure of the different concrete kinds of the utility model compared with prior art has the following advantages:
Although overlapping of three still can only pour into a mould the lightweight aggregate structural concrete identical with crossbeam, but be provided with the additional bar cage that comprises vertically to additional steel bar stress in overlapping of the three, and the additional bar cage has increased the ability of the lightweight aggregate structural concrete resistance to deformation at this place, so remedied the defective of lightweight aggregate structural concrete easy deformation under the load effect at this place, stopped potential safety hazard.
As improvement, the diameter of described additional steel bar stress is identical with the column steel bar stress, the all outstanding overlapping portion of three of the upper and lower side of described additional steel bar stress, outstanding distance is 40 times of additional steel bar stress diameter, like this, this additional bar cage is better to the concrete support effect of the overlapping portion of three.
