Vibration-isolating and noise-reducing rubber support for buildings

Abstract

The invention discloses a vibration-isolating and noise-reducing rubber support for buildings, which comprises a base, a top seat plate and a cylindrical vibration isolator, the base is a block with a sunken mounting cavity, the vibration isolator is arranged in the mounting cavity, the top seat plate covers the top end of the mounting cavity of the base and presses the vibration isolator, the bottom of the mounting cavity is provided with at least one pair of oppositely arranged guide blocks, and the guide blocks are extended along the circumference of the bottom of the inner wall of the mounting cavity and located around the vibration isolator, and hold the lower part of the vibration isolator. Since the lower part of the vibration isolator is held by the guide blocks of the vibration-isolating and noise-reducing rubber support, the guide blocks can be arranged at different positions according to actual requirement to control the horizontal deformation direction and displacement of the vibration isolator, thus ensuring that the concrete members of an upper structure supported by the support cannot be pulled and pressed to be damage due to excessive deformation under the action of the additional stress of vibration.

Description

technical field [0001] The invention relates to a building support, in particular to a building vibration-isolation and noise-reducing rubber support, which is especially suitable for being arranged in the intersection structure of an underground commercial space of an urban complex and a municipal road. Background technique [0002] With the continuous acceleration of urban development, the available land for construction is becoming increasingly scarce, and many buildings are developing from the sky to underground. Therefore, there are more and more cases where the underground commercial space of urban complexes intersects with municipal roads, which immediately leads to The following problem: the dynamic load generated by the vehicles traveling on the municipal road will generate vibration and additional stress on the structure of the underground commercial space. At the same time, the noise of the vehicle and the collision sound generated during the travel will also serio...

Problems solved by technology

However, the disadvantages of the basin-type rubber bearing are: since the vertical bearing capacity is mainly provided by the pelvic cavity, the vertical stiffness and vertical elasticity are poor; the side wall of the pelvic cavity is vertical, although it can meet the safety requirements, but, The material is not economical, and it also limits the displacement of the internal vibration isolator

[0005] For the municipal tunnel placed on the upper part of the underground commercial space structure, the horizontal vibration of the municipal tunnel can easily cause the concrete structure of itself and the underground commercial space structure to crack. However, the existing vibration isolation bearings are used in municipal roads When intersecting with the underground commercial space, it is impossible to control the horizontal deformation direction and displacement of the upper structure supported by it, so it cannot solve the problem of concrete structure cracking caused by the upper structure shaking from side to side under the action of additional vibration stress
