Problems solved by technology

Although some studies have tried to use the corresponding waiting model to propose a calculation method, the model is relatively complicated, and the current specification has not yet considered this factor well
Some scholars have also proposed to adopt a certain construction method to release the tangential force at the junction of the gusset plate and the beam-column, so that this tension effect can be ignored in the calculation and analysis, but it greatly affects the accuracy

Embodiment 1

[0029] Such as figure 1 with figure 2 As shown, this embodiment provides a corrugated supporting frame node structure, including a corrugated gusset plate 1 and a stiffening plate 2. The corrugated gusset plate 1 is a corrugated steel plate, and there are at least two stiffening plates 2 which are connected to the corrugated gusset plate in anti-symmetric 1 on.

[0030] The corrugation direction of the corrugated gusset plate 1 is perpendicular to the direction of the force, which can effectively transmit the axial force transmitted by the support, and the use of the corrugation (that is, the accordion shape) feature can effectively avoid the additional stress caused by the tension of the beam and column. In this embodiment, the corrugation type of the corrugated gusset plate 1 is a sawtooth waveform.

[0031] The corrugated gusset plate 1 is a square plate with cut corners. One end with cut corners can be easily connected to the support, and the two sides corresponding to the opp...

Embodiment 2

[0040] reference Figure 1-Figure 4 As shown, in the corrugated supporting frame node structure of this embodiment, the corrugation type of the corrugated gusset plate 1 is a trigonometric function waveform. The rest is the same as in Example 1.

Abstract

The invention relates to a corrugated supporting frame joint structure and a manufacturing and mounting method thereof. The corrugated supporting frame joint structure comprises a corrugated joint plate (1) and two or more stiffening plates (2); and the corrugated joint plate (1) is a corrugated steel plate, and the two or more stiffening plates (2) are antisymmetrically connected to the corrugated joint plate (1). Compared with the prior art, the corrugated joint plate has high rigidity and bearing force in one direction, and the very low rigidity and bearing force in the other direction, hashigh out-of-plane stability and good bearing performance, and meanwhile can effectively release additional stress caused by the beam-column tensioning and jointing effect.

Description

Technical field [0001] The invention belongs to the field of building structures, and in particular relates to a corrugated supporting frame node structure and a manufacturing and installation method thereof. Background technique [0002] Frame support structure is an important structural form. In recent years, more and more energy-dissipating structures that have been used in our country have also been installed in the frame structure by means of support connections. The connection between the support and the steel frame or the concrete frame is an important guarantee for this structural form and energy dissipation technology to function effectively. Studies have shown that the supporting gusset plate at the beam-column joints will have unfavorable additional stress on the gusset plate due to the tensioning effect of the beam-column. Although there have been studies that have tried to use the corresponding waiting model to propose a calculation method, the model is more complic...
