Abstract
The utility model discloses a bucking restraint is supported, it includes: the cross section of the outer sleeve is rectangular; the core material is inserted into the center of the outer sleeve along the axial direction of the outer sleeve, and the outer sleeve is filled with concrete to fix the core material in the outer sleeve; and the two supporting joint parts are respectively arranged at two ends of the core material and are exposed out of two ports of the outer sleeve. The utility model discloses bucking restraint is supported, the axial atress of its structure is more reasonable, and the performance of its buckling restrained material changes and ensures, and the economic nature promotion space of its structure itself is bigger.
Description
Technical Field
The utility model relates to a building engineering field of combatting earthquake especially relates to a bucking restraint support that is arranged in building structure to play supporting role.
Background
At present, the metal displacement type damper is the most important shock absorption device, wherein the buckling restrained brace is one of the most mature products in the metal displacement type damper. The actual stress condition of the core material in the buckling restrained brace and the compactness of the filled concrete playing a buckling restrained role have great influence on the mechanical properties and the fatigue properties of the buckling restrained brace, such as the bearing capacity and the like.
In the prior art, the buckling restrained brace generally adopts a finished steel pipe as an outer sleeve restraining member, and is formed by filling concrete vertically by utilizing gravity in a closed space. However, for a longer buckling restrained brace, the problem of insufficient bearing capacity of the structure is caused by the overall out-of-plane bending of the core material before pouring and the incompact concrete pouring, and the mechanical property and the fatigue property of the buckling restrained brace are influenced in practical application, so that the reliability of the buckling restrained brace is reduced.
In addition, because of the special tubing process required to pass the joint through the outer-sleeve constraining member, the outer-sleeve constraining member needs to have a sufficiently large size to ensure smooth passage of the joint for a high-load-capacity buckling restrained brace.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a bucking restraint is supported, the axial atress of its structure is more reasonable, and the performance of its buckling restrained material changes and ensures, and the economic nature promotion space of its structure itself is bigger.
In order to achieve the above purpose, the technical scheme of the utility model is that:
a buckling-restrained brace, comprising: the cross section of the outer sleeve is rectangular; the core material is inserted into the center of the outer sleeve along the axial direction of the outer sleeve, and the outer sleeve is filled with concrete to fix the core material in the outer sleeve; and the two supporting joint parts are respectively arranged at two ends of the core material and are exposed out of two ports of the outer sleeve.
Preferably, the outer sleeve is formed by welding four outer sleeve plates.
Preferably, the section of the core material is in a straight shape, a cross shape, an H shape or an I shape.
Preferably, the support joint is formed of a connection plate, and one end of the connection plate is connected to an end of the core material.
Preferably, the support joint further comprises a stiffener plate, which is placed perpendicular to the connection plate.
Compared with the prior art, the beneficial effects of the utility model reside in that:
aiming at the current situation that the outer sleeve of the current buckling restrained brace adopts a square finished steel pipe, the buckling restrained brace provided by the utility model is formed by mutually splicing flat plates by changing the structure of the outer sleeve into a structure, so that the pipe penetrating process can be omitted, and the core material can be ensured to be positioned at the central position of the outer sleeve before concrete pouring; the pouring and tamping quality is controlled during concrete pouring, and the filling is ensured to be compact; under the action of large bearing force, the outer sleeve and the support joint part can be respectively designed correspondingly as two independent elements, so that the freedom degree of the section design of the outer sleeve rectangular pipe can be improved; on the other hand, the economical efficiency of the buckling restrained brace is improved by optimizing the section size of the outer sleeve rectangular pipe. Secondly, the structure can not only ensure that the core material does not bend out of the surface; and can guarantee the closely knit degree of filling the concrete in the outer tube, and then very big assurance buckling restrained brace's mechanical properties and fatigue property.
