[0020] Specific implementation mode two: combination Figure 8~Figure 10 Note that the double-gusset plate in this embodiment includes a rear gusset plate 6-1 and a front gusset plate 6-2, which are arranged in parallel with a gap between them; the rear gusset plate 6-1 and the front gusset plate 6-2 The geometric dimensions are consistent, including two vertical sides, two horizontal sides and one hypotenuse. The specific dimensions need to be comprehensively determined according to the bearing capacity of the joint weld between the gusset plate and the beam-column, the horizontal angle of the support and the width of the support node. , the rear gusset plate 6-1 and the front gusset plate 6-2 are provided with a rectangular channel in the direction of the vertical line of the hypotenuse, its width is 1-2mm larger than that of the supporting stiffener 7-2, and its length is the same as that of the supporting stiffener The lengths of the parallel sections of the ribs 7-2 are c...

specific Embodiment approach 3

[0021] Specific implementation mode three: combination Figure 11~Figure 13 Note that the anti-buckling support node 7 in this embodiment includes a core plate 7-1 and two stiffening ribs 7-2, the stiffening ribs 7-2 are symmetrically arranged on both sides of the center line of the core plate 7-1, and are connected with the core plate 7-1 is vertical, the plane where the short side of the stiffener 7-2 is located has a 45-degree bilateral groove along the length direction, and the stiffener 7-2 is connected to the core plate 7-1 through the fillet weld 9-3 at the groove position For connection, there are bolt holes along the length direction on the core plate 7-1 on both sides of the stiffener 7-2, and the positions of the holes are arranged symmetrically with respect to the stiffener 7-2. With such a setting, it is easy to install and locate, convenient for on-site welding and connection, and the connection is reliable.

Abstract

In order to solve the problems of too long node connection length, difficult construction installation positioning, great steel consumption and the like of a conventional buckling-restrained brace one-gusset-plate connecting mode, the invention further provides a double-gusset-plate clamping type buckling-restrained brace bolt and welding hybrid connecting node with the advantages that the node connection length and the steel consumption can be reduced to the maximum degree; the construction installation positioning is simple; and the plane outer stability is good. By aiming at solving the technical scheme, the double-gusset-plate clamping type buckling-restrained brace bolt and welding hybrid connecting node adopts the technical scheme that the connecting node comprises double gusset plates, a buckling-restrained brace node, a friction type high-strength screw bolt and connecting weld lines.

Description

technical field [0001] The invention relates to a clamping type anti-buckling support bolted and welded hybrid connection node of double-node plates, which belongs to the field of anti-seismic building structures. Background technique [0002] Anti-buckling braces ( figure 1 ) is an efficient energy-dissipating shock-absorbing device, which has been increasingly used in multi-story buildings to achieve the purpose of structural shock absorption. Generally ( Figure 2~Figure 7 ), the support node 1 and the frame gusset plate 3 are all cross-shaped sections, and they can be connected by bolts through eight splicing plates 2 or welded by butt welds 5 . Such traditional connection methods have the following problems: [0003] (1) The connection length of traditional bolted joints [0004] Traditional bolted joints ( Figure 2~Figure 4 ) need to use eight splicing plates 2 as transition plates to connect the support node 1 and the gusset plate 3 at the same time, resulting i...
