Description

Flexible mutual-supporting type anti-vibration structure

Technical Field

The utility model belongs to the technical field of anti-vibration structure, concretely relates to flexible mutual supporting formula anti-vibration structure.

Background

In the design process of a large building, in order to improve the anti-seismic performance of the structure or reduce the temperature difference stress of the overlong structure, a parting mode is usually adopted in the design, namely a mode that a main structure is completely disconnected is adopted, so that the main structures of the monomers on the two sides are completely independent. The main structure parting usually adopts a double-column breaking mode and a mid-span breaking mode; the midspan disconnection mode is that the structural joint is arranged in the midspan of the beam, the structure supported at two ends is changed into a structural form that two side members are independently cantilevered, when the parting joint is arranged between midspans with larger span, the cantilever length is also larger, and the cantilever length at two sides of the parting joint is larger than 4 meters in some buildings; to ensure the clear height of the indoor use, the height of the large span beam is usually limited; in the parting place, because the original beam with two rigidly connected ends is changed into a single-side cantilever beam, under the condition that the beam height is not changed, great challenges are brought to the design work, and particularly, the vertical vibration at the overhanging far end, namely the mid-span parting position, is difficult to control.

The vibration of the floor slab in the pedestrian process is usually ignored in the design, the problem of the floor slab vibration is not very outstanding in the large-span beam with two ends rigidly connected, but the vertical vibration is more obvious in the large overhanging position, and if no measure is taken during the design, the great adverse effect is brought to the use comfort level in the use process.

When the existing mid-span parting is broken, the following methods are generally adopted for solving the problem: 1. two sides of the structural joint are respectively cantilevered out of the beam from the column side, and the cantilever beam can be in the form of a reinforced concrete beam, a steel beam, a profile steel concrete beam and the like; 2. edge sealing beams are arranged at two ends of the cantilever beam, and the width of a structural joint is reserved between the edge sealing beams at two sides; 3. the two sides of the structural seam are independent structures, and independent deformation of the structural seam does not affect each other; the disadvantages of the current structural seams are as follows: 1. when the span is great, encorbelment for a long time promptly, because the component size of encorbelmenting receives the restriction of indoor net height, can only satisfy the bearing capacity demand of floor through increasing reinforcing bar or steel sheet thickness. At the moment, the vibration of the overhanging far end, namely the mid-span parting position, is difficult to control; 2. the structure seam both sides are the totally independent structure, solve the operation requirement of building completely through encorbelmenting, do not utilize current condition.
