Support pedestal assembly including a stabilizing collar for stabilizing a support structure

Abstract

A support structure for elevating a building surface above a fixed surface having stability bracing to provide increased stability to the structure. The support structure includes a plurality of support pedestals that are disposed in spaced-apart relation on a fixed surface. A plurality of braces are attached to adjacent support pedestals to interconnect the support pedestals. Interconnecting the support pedestals in such a manner creates a stable support structure that can be utilized in unstable environments, such as seismically active geographic areas. The support pedestals can be adjustable-height support pedestals.

AI Technical Summary

Benefits of technology

[0011]It is therefore an objective to provide a support structure for an elevated surface, where the support structure has improved structural stability. It is also an objective to provide a support structure that can enable the safe construction of an elevated surface having an increased height above the fixed surface as compared to existing support structures, particularly in areas that are prone to disruptive vibrations.

[0015]According to another aspect, one or more of the braces can have an adjustable length. Adjustable length braces can be particularly advantageous to accommodate the use of surface tiles having edge portions of different lengths, e.g., rectangular tiles that are not square.

[0024]In accordance with the foregoing embodiments and aspects, the support structure can provide increased structural stability. In one aspect, the support structure can be used to support elevated surfaces in seismically active geographic areas or in other areas where disruptive vibrations may occur, such as a train platform. Through interconnection of the support pedestals, the support pedestals can move in unison during a seismic event or other vibratory disruption to maintain the desired spacing between the support pedestals, and therefore continue to safely support surface tiles placed on the support pedestals and maintain the integrity of the building surface.

[0025]The support structure can have an increased structural stability, thereby enabling the use of support pedestals having an increased height without adversely affecting the stability of the elevated surface. For example, the support pedestals can have a height of greater than 24 inches and even up to about 36 inches or more.

[0026]The braces can be rapidly and easily attached to the support members during construction of the support structure. The braces can also be configured to prevent twisting of the support pedestals in relation to adjacent support pedestals.

Problems solved by technology

One problem that is associated with some support structures for elevated surfaces is that the support structures do not provide adequate structural stability in certain unstable environments.

As a result, the support structures cannot be safely utilized in certain seismically active geographic areas, high wind areas or other locations that may be subject to disruptive vibrations of the fixed surface.

Another problem associated with some support structures for elevated surfaces is that the safely obtainable height of the support pedestals is limited due to the increasing instability of the support pedestals as the height of the pedestals, and hence the center of gravity of the pedestals, is increased.

The increased height of the center of gravity further compounds the problems associated with disruptive vibrations of the underlying surface.
