Vibration-damping band for substituting speed hump to reduce floor slab vibration

Abstract

The invention provides a vibration-damping band for substituting a speed hump to reduce floor slab vibration. The speed hump is mounted on the upper surface of a floor slab of a building structure, and not only plays a role of slowing down a vehicle, but also can reduce a load of the vehicle on the floor slab in the running process; the speed hump comprises an upper steel plate layer, a lower steel plate layer, and a middle soft rubber layer with a buffer effect; the integral height of the speed hump is smaller than that of a commonly-used speed hump; the vibration-damping effect of the speed hump is mainly embodied as follows: the rubber layer with relatively small elastic modulus has relatively great shearing deformation under the collision of the fast running vehicle and thus a part of energy is dissipated; the speed hump of which the upper surface is relatively flat effectively inhibits a galloping phenomenon when the fast running vehicle runs through the speed hump; the speed hump is relatively wide, so that after the fast running vehicle runs through the speed hump and jumps slightly, the fast running vehicle still falls onto the speed hump with relatively small vertical rigidity so as to weaken transmission of a vertical impact load to the ground surface or the floor surface.

Description

technical field [0001] The invention relates to the field of vibration control of building structures, in particular to a vibration-absorbing belt for floor comfort control. Background technique [0002] The deceleration belt is a traffic facility installed on the road to slow down the passing vehicles. It is necessary to set the deceleration belt in the necessary position on the road. With the wide use of parking lots in buildings, for safety reasons, it is necessary to install them in the parking lot of the building. Speed ​​bumps need to be installed. [0003] When a vehicle passes through a deceleration belt of a certain height at a speed exceeding a certain speed limit, it will generate a large load on the floor. This vehicle impact load acts on the floor to cause the floor to vibrate, and the vibration of the floor of some buildings The acceleration does not meet the requirements for building comfort in the code. However, the vehicle impact load caused by this spee...

Problems solved by technology

[0003] When a vehicle passes through a deceleration belt of a certain height at a speed exceeding a certain speed limit, it will generate a large load on the floor. This vehicle impact load acts on the floor to cause the floor to vibrate, and the vibration of the floor of some buildings The acceleration does not meet the requirements of building comfort in the code

However, the vehicle impact load caused by this speed bump was not considered in the structural design stage, and a solution should be given to the problem that the structure does not meet the comfort level due to the vehicle impact load
