Embodiment

[0015] Example: such as Figure 1-Figure 3 As shown, the present invention comprises a main girder 1 and a steel keel lattice unit connected in parallel between two main girders 1. The steel keel lattice unit includes a neck plate 2, a bottom plate 5, two steel keels 3 and a brace 4. The two steel keels 3 are arranged side by side, one end is connected to the neck plate 2, the other end is connected to the bottom plate 5, and a plurality of reinforcement bars 4 are arranged between the two steel keels 3, the neck plate 2 is connected to the lower surface of the main beam 1, and the bottom plate 5 is connected to the main beam. On the upper surface of the beam 1 , there is a gap between the main beam 1 and the steel keel 3 connecting the ends of the neck plate 2 to meet the deflection deformation of the main beam 1 .

[0016] Such as Figure 1-Figure 5 As shown, the steel keel 3 is a grooved structure.

[0017] Such as Figure 4 As shown, the neck plate is a trapezoidal stru...

Abstract

The invention provides an earthquake-resistant energy-dissipation connecting structure for steel joists and girders, and belongs to the technical field of buildings. The connecting structure comprises the girders and steel joist lattice units connected between the two girders side by side; each steel joist lattice unit comprises a neck plate, a bottom plate, two steel joists and tension bars, wherein the two steel joists are arranged side by side, one end of each steel joist is connected with the neck plate, the other end of each steel joist is connected with the bottom plate, and multiple reinforcing tension bars are arranged between the two steel joists; the neck plates are connected to the lower surfaces of the girders, the bottom plates are connected to the upper surfaces of the girders, and gaps for meeting flexural deformation of the girders are reserved between the girders and the ends, connected with the neck plates, of the steel joists. The special neck plates are used for reliably connecting the joists and the girders into a whole, the overall stability of an outer wall is enhanced, due to the fact that the neck plates can buffer deflection of the girders, vertical loads transmitted by the girders cannot be directly exerted on the joists, bending and buckling of the joists are avoided, engineering quality is effectively improved, and the earthquake-resistant energy-dissipation condition of a building structure is improved. Deformation of the girders is buffered, and lateral deflection of the joints is avoided.

Description

technical field [0001] The invention belongs to the technical field of construction, in particular to an anti-seismic energy-dissipating connection structure of a steel keel and a main girder. Background technique [0002] In recent years, various new types of exterior wall panels have been gradually applied to different building structures. Most of the exterior wall panels in my country use light steel keels as the internal support system of the wall. In this way, the connection method between the keel and the main structure (especially the main beam) directly affects the overall stiffness of the wall and the ability to resist earthquakes and dissipate energy. Solving this difficult problem can improve the engineering quality and the anti-seismic ability of building structures. So far, many experiments and exterior wall manufacturers have been exploring and practicing, trying to determine a more effective connection method that can improve the wind resistance and earthquak...
