Problems solved by technology
[0005] However, the limitation of this buckling support device 9 is that the structural concrete can only be poured into the support sleeve 921 after the axial force member 91 has to be sleeved in the support sleeve 921. Therefore, the axial force member The two ends of 91 are used to connect to the end of the steel structure, and its volume cannot exceed the caliber of the supporting sleeve 921. However, the contact area between the end of the axial force member 91 and the steel structure is related to the buckling of the supporting device. 9 can absorb the size of the strength from the steel structure

Embodiment Construction
[0036] The present invention is described in detail below in conjunction with accompanying drawing and three embodiments:
[0037] Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.
[0038] refer to Figure 2 to Figure 4, The first preferred embodiment of the restraint system support device 100 of the present invention includes an axial member 1 , a restraint member 2 and two end plates 3 .
[0039] The axial force member 1 includes two ends 11 and a middle section 12 connected between the two ends 11, the enclosing member 2 is used to cover the middle section 12 of the axial force member 1, and the two ends 11 are exposed. They can be respectively connected and fixed at two places of the steel structure of the building (for example, two places at the opposite corners of the steel structure), so that the whole buckling system support device 100 can be erected and fix...

The invention relates to a buckling restrained brace, which comprises a shaft force member and a confined member. The shaft force member comprises an intermediate segment; the confined member comprises a first side shell piece and a second side shell piece; a first hollow side and at least one first positioning groove positioned in the first hollow side are formed on the first side shell piece; asecond hollow side and at least one second positioning groove positioned in the second hollow side are arranged on the second side shell piece; and the first side shell piece and the second side shell piece can be used for connecting the first hollow side and the second hollow side to make the intermediate segment of the shaft force member wrapped between the first side shell piece and the secondside shell piece; and the two parts of the intermediate segment are partially and respectively embedded into the first positioning groove and the second positioning groove.
Description
technical field [0001] The present invention relates to a buckling restraint support device and its manufacturing method, in particular to a buckling restraint support device and its manufacture for erecting in the structure of a building to prevent the structure of the building from buckling under pressure method. Background technique [0002] Buckling Restrained Braces (BRB) are used to build on the steel structure of the building. When an external vibration (such as an earthquake) occurs, the Buckling Restrained Braces can first bear the floor shear force, Instead of the steel structure, first generate energy dissipation to avoid damage to the steel structure. [0003] Such as figure 1 As shown, it is a buckling restraint support device 9 disclosed in U.S. Patent No. US7,284,358, which includes an axial force member 91 and a buckling resistance unit 92. A support sleeve 921 sleeved outside the axial force member 91 and a structural concrete layer 922 filled in the supp...
