Extended kerf cut and spline restraint system for elevated flooring surfaces

A method for use in constructing an elevated building surface assembly, comprising:

• locating a plurality of support members over a fixed surface with a predetermined spacing between the support members;
• first placing first and second adjacent corner portions of a first of a plurality of building surface components over respective first and second of the plurality of support members;
• second placing first and second adjacent corner portions of a second of the plurality of building surface components over the first and second support members;
• and
• receiving a spline into openings in abutting outer edge segments of the first and second building surface components, wherein the first and second building surface components are free of connections to the first and second support members.

An elevated building surface assembly, comprising:

• a support structure including a plurality of support pedestals disposed in spaced-apart relation on a fixed surface, the support pedestals including:
• a base member;
• a support member including a support plate;
• and
• a central section interconnecting the base member and the support member;
• a plurality of building surface components disposed on the support plates of the support pedestals, the building surface components including:
• a top surface;
• a bottom surface;
• a plurality of corner portions;
• and
• an outer edge segment disposed between adjacent corner portions, wherein at least one of the outer edge segments includes an opening therein that extends from a first of the corner portions to an adjacent second of the corner portions;
• and
• a spline disposed in the openings of abutting outer edge segments of first and second adjacent ones of the plurality of building surface components, wherein the first corner portions of each of the first and second building surface components are disposed over a first of the plurality of support pedestals, wherein the second corner portions of each of the first and second building surface components are disposed over a second of the plurality of support pedestals that is adjacent the first support pedestal, wherein the first and second building surface components are free of connections to the first and second support pedestals, and wherein the spline is at least partially disposed over at least one of the first and second support pedestals.
