Specific embodiment
This utility model is more fully illustrated below with embodiment.This utility model can be presented as it is various not Same form, is not construed as the exemplary embodiment for being confined to describe here.
For ease of explanation, here can using " on ", the space relative terms such as D score " left side " " right side ", for saying The element illustrated in bright figure or feature are relative to another element or the relation of feature.It should be understood that except in figure Outside the orientation for illustrating, spatial terminology is intended to include device different azimuth in use or operation.For example, if in figure Device is squeezed, be stated as positioned at the element of other elements or feature D score will be located into other elements or feature " on ".Cause This, exemplary term D score can be comprising both upper and lower orientation.Device otherwise can be positioned(It is rotated by 90 ° or is located at Other orientation), correspondingly can explain used herein of the relative explanation in space.
As shown in figure 1, the two-tube coupled column with energy-dissipating and shock-absorbing effect in the present embodiment, is included in what is arranged in metope Two steel pipe column limbs, 1, one group of intercolumniation beam 2 and post side bracket beam 3;Intercolumniation beam 2 is arranged between steel pipe column limb, is welded with steel pipe column limb Connect in succession, with group post side bracket beam with intercolumniation beam in same plane;Bolt mounting holes are provided with the bracket beam of the post side.
As shown in Fig. 2 when the two-tube coupled column with energy-dissipating and shock-absorbing effect is arranged on the centre of building, with group post side bracket There are 2 pairs of post side bracket beams to be arranged in parallel and stretch out the metope in beam.
The steel tube section shape of steel pipe column limb 1 can be the form such as circular, square, rectangle and polygon.
The steel pipe of steel pipe column limb 1 can be cold bending rectangle steel pipe or the welding rectangular steel pipe for being formed is welded by steel plate.
In order to improve the intensity of steel pipe column limb 1, can be with steel pipe concrete filled formation steel core concrete column limb.
Intercolumniation beam 2 can adopt H types section;Post side bracket beam 3 can also adopt H types section;Intercolumniation beam 2 and post side bracket Beam 3 can adopt welded H section steel, hot rolled H-shaped or high frequency welding of H-structural steel.
During two-tube coupled column of the welding with energy-dissipating and shock-absorbing effect, steel pipe column can be run through using by the edge of a wing of intercolumniation beam 2 Limb 1, the technical scheme that steel pipe column limb 1 is disconnected at the edge of a wing of intercolumniation beam.1 stress of steel pipe column limb based on pressure, after disconnection, Two parts steel pipe is connected with the edge of a wing of intercolumniation beam using welding manner up and down, and the impact to 1 bearing capacity of steel pipe column limb is little, phase Ying Di, the edge of a wing of intercolumniation beam are not affected by steel tube section by the cross section through steel pipe column limb 1, the edge of a wing, can be increased, be carried The high tensile strength of intercolumniation beam;So as to improve the intensity of the two-tube coupled column with energy-dissipating and shock-absorbing effect on the whole.
By the edge of a wing of intercolumniation beam 2 and the edge of a wing Integral design of post side bracket beam 3;Be conducive to improving the strong of post side bracket beam 3 Degree.
Process for convenience, the two-tube coupled column with energy-dissipating and shock-absorbing effect should be in factory's segmental machining;Can be with layer For unit, two-tube pole unit is formed.If had greatly with 3 layers as a two-tube pole unit, working (machining) efficiency and site operation efficiency Width is improved.The connecting method of steel pipe column limb 1 can be spliced using flange, splice at the scene;After can also being segmented, construct at the scene Shi Liyong welding manners splice.
During the scheme spliced using flange, the stitching position of steel pipe column limb 1 can be with as shown in figure 4, be set in node district Splice in domain;Can also be set to as shown in Figure 5 splice outside node region.
Connected by little bracket between post side bracket beam 3 and crossbeam 4 or longeron 5, i.e. the bottom of post side bracket beam 3 is stretched out, Form supporting construction, referred to as little bracket;Girder steel is overlapped on little bracket, and the axis of bolt is perpendicular to horizontal faying surface;Can also Connected by connecting plate.Connecting bolt preferably selects high strength exploitation.
As shown in figure 3, the spacing of steel pipe column limb 1 can be adjusted as needed;Can arrange between steel pipe column limb 1 triatic stay, Support, corrugated steel shear wall, steel plate shear force wall, combined steel plate shearing force wall etc..
After connection, by casting craft, by the two-tube coupled column acted on energy-dissipating and shock-absorbing and crossbeam 4, longeron 5 pour into In metope and floor topping;Avoid the loosening and corrosion of bolt in attachment structure;Meanwhile, also make building interior, outside seem more Plus it is attractive in appearance.
The invention also discloses the construction method of the above-mentioned two-tube coupled column with energy-dissipating and shock-absorbing effect, including it is as follows Step:
1)The two-tube coupled column and girder steel and connector with energy-dissipating and shock-absorbing effect is made in factory, is made with three layers For a two-tube pole unit;It is of course also possible to using one layer or 2 layers as a two-tube pole unit;
2)Transport to scene, two-tube pole unit is passed through into crab-bolt, high-strength bolt with basis or lower floor's post or is weldingly connected;
3)After two-tube pole unit installation, girder steel is shelved on this by the girder steel that layering lifting is connected with two-tube pole unit On the bracket beam of layer corresponding post side, using high-strength bolt connection girder steel and post side bracket beam, steel frame construction is formed;
4)After the steel frame construction is connected, truss hoisting reinforcing bar superimposed sheet is laid the line, and live colligation flooring is born Muscle, carries out floor concrete and pours;The web height of concreting to post side bracket beam, then overlying building coats is to girder steel More than top flange 20 ~ 50mm;Girder steel is avoided by building coats and splices node with the two-tube coupled column with energy-dissipating and shock-absorbing effect Expose;Or concreting is extremely concordant with girder steel top flange, or it is higher by 30 ~ 100mm of girder steel top flange;Will by concrete Girder steel is hidden in building cover structure completely with the two-tube coupled column splicing node with energy-dissipating and shock-absorbing effect, makes bolt and splice plate Do not expose.
5)Light external wall plate is lifted from outside so as to be embedded in framework that adjacent dual string and intercolumniation beam or girder steel formed it Between, and it is connected with intercolumniation beam or girder steel, plasters to concordant with light external wall plate inner surface in dual string post limb indoor.Gently Matter exterior wall plate thickness more than the dual string limb height 30 ~ 120mm, the latticed column can hide completely and exterior wall in.
Above-mentioned example is only intended to explanation this utility model, in addition, also various different embodiments, and these Embodiment be all those skilled in the art after comprehension this utility model thought it is also envisioned that therefore, a here no longer string Lift.
