specific Embodiment approach 1

[0018] Specific implementation mode 1: Combination Figure 8~Figure 13 Explain that the double gusset plate clamping type anti-buckling support bolt-welded hybrid connection node of this embodiment includes a back gusset plate 6-1 and a front gusset plate 6-2, with a gap between them and arranged in parallel , And the flange surfaces of the beam and the column are perpendicular to each other and connected by welding seams; the connecting nodes also include anti-buckling support nodes 7, friction type high-strength bolts 4, and connecting welds 9-1 to 9-3.

[0019] The core plate 7-1 of the supporting node is inserted into the gap between the double gusset plates 6-1 and 6-2, and the two stiffening ribs 7-2 are inserted into the back gusset plate 6-1 and the front gusset plate 6-2 respectively. In the channel, and align the bolt holes of the dual gusset plate 6 and the core plate 7-1 in unison, friction type high-strength bolts 4 are passed between the back gusset plate 6-1 and the...

specific Embodiment approach 2

[0020] Specific implementation manner two: combination Figure 8~Figure 10 Note that the dual gusset plate in this embodiment includes a back gusset plate 6-1 and a front gusset plate 6-2, with a gap between them and arranged in parallel; the back gusset plate 6-1 and the front gusset plate 6-2 The geometric dimensions are the same, including two vertical sides, two horizontal sides and one hypotenuse. The specific dimensions need to be determined comprehensively according to the bearing capacity of the connection weld between the gusset plate and the beam-column, the horizontal angle of the support, and the width of the support node , The back gusset plate 6-1 and the front gusset plate 6-2 are provided with a rectangular channel in the perpendicular direction of the hypotenuse, the width of which is 1-2mm larger than the width of the support stiffener 7-2, and its length is consistent with the support stiffening The length of the parallel section of the rib 7-2 is the same, th...

specific Embodiment approach 3

[0021] Specific implementation mode three: combination Figure 11~Figure 13 It is explained that the anti-buckling support node 7 of 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 to the core plate 7-1. 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 a fillet weld 9-3 at the groove position For connection, the core plates 7-1 on both sides of the stiffening rib 7-2 are provided with bolt holes along the length direction, and the positions of the holes are symmetrically arranged with respect to the stiffening rib 7-2. Such a setting is easy to install and locate, convenient to weld and connect on site, 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 double-node plate clamping type anti-buckling support bolt-welded hybrid connection node, which belongs to the field of seismic resistance of building structures. Background technique [0002] Anti-buckling support ( figure 1 ) Is an efficient energy-consuming and shock-absorbing device, which has been increasingly used in multi-high-rise buildings to achieve the purpose of structural shock absorption. Generally ( Figure 2~Figure 7 ), the support node 1 and the frame node plate 3 are both cross-shaped cross-sections, and they can be connected by bolts through eight splicing plates 2 or welded through butt welds 5. Such traditional connection methods have the following problems: [0003] (1) The connection length problem of traditional bolt connection nodes [0004] Traditional bolted joints ( Figure 2~Figure 4 ) It is necessary to use eight splicing plates 2 as transition plates to connect the supporting node 1 and the node plate ...
