Abstract

The invention discloses a beam and pillar node dry connection fan-shaped viscoelastic damper. A complex energy dissipation support body is mainly composed of a plurality of elastic units, a plurality of rigid units, rigid plates, a positioning limiting device and a stretching device which are stacked alternately. Each rigid unit is composed of the two fan-shaped rigid plates which are fixedly connected with a beam connection plate and a pillar connection plate correspondingly; each elastic unit is composed of two fan-shaped elastic plates; fan-shaped buffering areas are arranged between the left edge and the right edge of each rigid plate and the beam connection plate and the pillar connection plate; strip-shaped buffering areas are arranged in the center of each fan-shaped rigid unit and each fan-shaped elastic unit, and a notch is formed in each of the two ends of each strip-shaped buffering area; two through holes are formed in each fan-shaped rigid plate; the stretching device is connected with the through holes; a pair of long holes are formed in the rigid unit on the outer side, positioning concave platforms are formed in one sides of the oblong holes; the positioning limiting device is installed in cooperation with the outer side rigid unit for limiting and positioning; and the damper can deform tangentially and radially. The damper is good in damping performance and remarkable in energy dissipation effect.

Description

technical field

[0001] The invention belongs to the field of engineering structures, and relates to building components for beam-column joint connection, position limitation and shock absorption, in particular to a sector-shaped viscoelastic damper for beam-column joint dry connection. Background technique

[0002] Under the action of earthquakes, the frame structure must meet the "strong earthquake resistance" and the frame structure must provide sufficient deformation capacity under the action of wind load. The frame must have good energy dissipation capacity and deformation capacity. The traditional frame structure relies on the consumption of the structure itself. Energy and provide deformation, limited ability. A reasonable and effective anti-seismic approach is to install anti-seismic devices on the structure, and the anti-seismic devices and the structure jointly bear the seismic action, that is, jointly store and dissipate seismic energy, so as to reduce and adjust t...

Embodiment Construction

[0035] Attached below Figures 1 to 16 The present invention is further described.

[0036]Solution 1 of the present invention provides a sector-shaped viscoelastic damper for beam-column joint stem connection, which includes a composite energy-dissipating support body 1, a beam connecting plate 3, a column connecting plate 4 and a position-limiting device, the lower end of the beam connecting plate 3 and the column The left end of the connecting plate 4 has an upright U-shaped groove part one 5 and an inverted U-shaped groove part two 6 respectively, and the left side wall of the U-shaped groove part two 6 is snap-fittingly arranged In the notch, the cooperation between the U-shaped groove part one 5 and the U-shaped groove part two 6 makes the beam connection plate 3 and the column connection plate 4 have a rotation range of 80-100 degrees, that is, the beam connection plate 3 and the column connection plate The connecting plate 4 passes through the U-shaped groove part 1 5...
