Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a connecting structure of a steel truss corridor. Background Art

[0002] Corridor structures are widely used between high-rise buildings. At present, the connection forms between the corridor and the tower mainly include rigid connection and weak connection. When the number of floors with corridors is small, in order to ensure the free deformation of the main structures on both sides of the corridor under major earthquakes, a weak connection method is generally adopted. The weak connection usually adopts a connection form with one end hinged and the other end sliding or both ends sliding, and a support body (usually a corbel) needs to be set at the bottom of the main structure of the corridor. This form has relatively complex construction measures, and due to its large volume, it will affect the aesthetic degree of the building facade. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a steel truss corridor connecting structure with good seismic performance, simple structure and no influence on the building facade effect.

[0004] To solve the above technical problem, the technical solution of the utility model is a steel truss corridor connecting structure, including a steel truss corridor and towers on both sides of the steel truss corridor; both ends of the steel truss corridor are fixedly connected with corridor wing plates; several supports are fixedly connected to the bottom of the corridor wing plates; friction pendulum bearings are installed between the supports and the towers.

[0005] Further, the corridor wing plate adopts a steel truss structure.

[0006] Further, the corridor wing plate is integrally connected with the steel truss corridor.

[0007] Further, several supports are inclined; the bottom end of the support is welded to the surface of the upper seat plate of the friction pendulum bearing.

[0008] Further, the included angle between the support and the horizontal plane is 30° - 60°.

[0009] Further, a support stiffening plate is also fixedly connected between the bottom end of the corridor wing plate and the surface of the upper seat plate of the friction pendulum bearing.

[0010] Further, the connecting sleeve of the friction pendulum bearing is embedded in the tower.

[0011] Further, corridor wing plates are fixedly connected to the four corners of the steel truss corridor.

[0012] Advantages of the Utility Model:

[0013] The utility model adopts a new connecting structure for the corridor. At both ends of the steel truss corridor, corridor wing plates are connected. Friction pendulum bearings are installed on the tower buildings, and the corridor wing plates and the friction pendulum bearings are connected through the bearings. The structure of the utility model is simple. By utilizing the self-centering ability and the anti-torsion ability of the friction pendulum bearings, the influence of the corridor on the main building structure can be reduced, so that the building structure has good seismic performance; the bracket member such as a corbel is omitted, the self-height of the friction pendulum bearing is small, and the bearing is located at the roof position, which basically has no influence on the external facade effect of the building.
