Abstract
The utility model discloses a non-binding steel-reinforced concrete anti-buckling energy dissipation brace, which is arranged with nuclear steel-reinforced components. The utility model is characterized in that the core steel-reinforced components are cross-shaped (1.1) or I-shaped (1.2) or H-shaped (1.3) and O-shaped (1.4) components made of stripe-shaped steel plates; a layer of non-binding layer (7) composed of paint or coating, asphalt and polyethylene film is arranged on the outer surface of the core steel-reinforced components, and restricting bodies (2.1 and 2.2) made of reinforcing steel bars (3.1 and 3.2) and concrete are arranged outside the non-binding layer. The brace is suitable for the braces of various frameworks, and has the advantages of reasonable structure, easy manufacture and installation, good solidifying and supporting effect, and steel saving.
Description
Technical field
The utility model belongs to the reinforcing support that is used to resist horizontal force actions such as earthquake wind load in a kind of building, particularly is used in the support of various steel framed structures, composite frame structure and reinforced concrete frame structure.
Background technology
The frame construction of being made up of steel member, combined member or reinforced concrete member is a frequent adopted form of structure in the building.When earthquake or wind action, have stronger lateral rigidity for making this structure, the horizontal force that opposing seismic forces and wind load produce is provided with various supports in the framework of being everlasting, and general the support mostly is steel or combined member, supports and mainly bears pulling force or pressure.
When being supported on tension, steel can bear bigger load.During pressurized, satisfying intensity simultaneously, unstability might take place in member section, forms buckling failure, and instability status is relevant with length ratio (being slenderness ratio) with the cross section of member, and the support in the framework generally all will be considered tension and pressurized.For the flexing unstable phenomenon does not take place too early, will select bigger supporting section for use, and expend more steel.
Make steel be supported on the pressurized tension state and have same performance, need prevent to support too early generation flexing.In supports outer obligatory point is set, the lateral deformation that restriction is supported can make when being supported on the tension pressurized and all can select less cross section by tension state.The steel support is the primary structure member in the structure, and it is stressed to require obligatory point not participate in, and need establish isolated material between steel support and obligatory point, is no bond state.
In frame construction, steel supports the lateral force resistance effect of playing, make structure form bigger lateral rigidity, but do the time spent, wish that steel supports generation surrender earlier and caused destruction when violent earthquake, lose the lateral force resistance effect, so the structure lateral rigidity diminishes, act on structural seismic forces and also just diminish, make main supporting member pillar and beam avoid destroying, guaranteeing that building is unlikely collapses the power consumption effect of structure that Here it is.Need supporting section only to guarantee to have the lateral resisting ability when little shake or middle shake, the cross section can not be excessive, and steel strength is preferably lower, i.e. the low-yield steel.Support will possess above function, just structure is played the effect of fuse in big shake effect.
Therefore, need existing support is being improved.
The utility model content
The purpose of this utility model is in order to solve the problems of the technologies described above, proposing a kind of nothing bonding steel reinforced concrete anti-buckling energy-consumption supports, this support can realize the needed function of above earthquake resistant structure preferably, and can reach the target that general steel supports the saving steel.
The purpose of this utility model is achieved through the following technical solutions: do not have bonding steel reinforced concrete anti-buckling energy-consumption and support, be provided with core reinforcing bar member, it is characterized in that: described core reinforcing bar member is the member of the cross made by the strip steel plate or in-line, H shape, O shape, and member adopts Q
354, Q
235, Q
215, Q
195, Q
100Steel etc. various materials; The external surface of this core reinforcing bar member be provided with one deck by paint or, the adhesive-less layer that constitutes such as coating, pitch, polyethylene sheeting, be provided with the obligatory point of making by steel concrete in the outside of this adhesive-less layer.
The profile of described steel concrete obligatory point is square or rectangle, circle, many prismatics, ellipse; Obligatory point adopts C
30And the concrete of above various strength grades.
The two ends of described core reinforcing bar member grow the two ends of steel concrete obligatory point, and link such as junction plate of the various types of attachment that link to each other with framework of setting, bolt hole.
The shape of above-mentioned supporting core reinforcing bar member can also be other different shapes such as square shape, T-shaped; Also various other the various materials that are difficult for boning with concrete of described adhesive-less layer are made, and its thickness can be adjusted according to the shape size of reinforcing bar member, and these variations all should be among protection domain of the present utility model.
The utility model since in core reinforcing bar member outer setting obligatory point, the lateral deformation that restriction is supported makes the reinforcing bar member have same performance at the pressurized tension state, can prevent to support too early generation flexing.Thereby under identical tension compressive property condition, can select the reinforcing bar member of small cross sections, save steel greatly.Adhesive-less layer is set in addition, in make supporting just the reinforcing bar member be stressed member, obligatory point does not participate in stressed, is no bond state.In frame construction, support and play the lateral force resistance effect, make structure form bigger lateral rigidity, but when violent earthquake took place, the yield strength of steel was low, ductility good, according to design idea owing to support, support and surrender earlier, so that destroy, lose the lateral force resistance effect, so the structure lateral rigidity diminishes, acting on structural seismic forces also just diminishes, make main supporting member pillar and beam avoid destroying, guaranteeing that building is unlikely collapses the power consumption effect of structure that Here it is.In actual use, need supporting section only to guarantee to have the lateral resisting ability when little shake or middle shake, the cross section can not be excessive, and steel strength is preferably lower, i.e. the low-yield steel.Support will possess above function, just structure is played the effect of fuse in big shake effect.The utlity model has novel and reasonable structure, easy to use flexibly applicability is strong, tool the be greatly improved effect of anti-seismic performance of frame construction and the advantage of saving steel.
