Definitions

  • This invention most generally relates to a flooring system for low rise buildings. More particularly this invention relates to a flooring system for residential type buildings. Most particularly this invention relates to a building fiooring system which combines two existing arts: timber joists and light-weight, wooden, trusses and/or beams. The combination produces a floor structure which is: simple to install, extraordinarily easy to fit with ancillary services, particularly convenient to repair and retrofit with new services, relatively sound proof, attractive from below, and familiar from above.
  • Disentanglement and separation of structure and services are known in the art but the systems are based on removable or semi -removable floor tiles laid over usually a concrete subfloor. These prior art systems work in concrete industrial or apartment buildings, where access from below is difficult structurally and complicated by concerns of neighbors below.
  • U.S. patent 4,676,036 describes an integrated raised flooring system for an office setting.
  • the system utilizes flooring panels placed between, and attached to raised, supporting pedestals which rest on a subfloor.
  • the floor panels do not rest on the top of the pedestals as is common with such flooring systems.
  • This flooring system is designed to be multi-tiered, to create more than one space between the subfloor and the ultimate office floor. Thus, several layers of flooring panel may be attached to the pedestals at various heights.
  • This system allows the various levels to act as separators for containing and isolating selected groups of utilities, for example to prevent noise interference, and to prevent wiring from resting directly on the subfloor to be subjected to possible water damage.
  • the flooring panels are removable, allowing access to the various utilities contained on the various levels.
  • U.S. patent 4,930,277 discloses a panel assembly and support structure for elevated floors in an office setting.
  • This particular system has two different flooring panels, access panels and base floor panels, arranged in a checkerboard fashion to provide support and easy adjustability of the floor system.
  • the system is designed for multi-level floors for areas such as stock trading pits.
  • the system is designed so that the levels of flooring may be quickly and easily readjusted to accommodate changing uses of the floor and the room.
  • This system uses panels placed on pedestals, and has detachable riser beams to provide assembly of multi-level, stepped, raised floors.
  • Vertical "closure panels" are provided to connect the various levels of flooring and close off the vertical space between the stepped flooring levels. There is space between the subfloor and the various floor levels, through which utilities may be run, but that is not the object of the invention.
  • U.S. patent 5,265,386 addresses a method and device for laying access floors, and access floor support. This invention is also directed to raised floors for an office setting, installed over a subfloor, and under which utilities may be run. The primary emphasis of this invention is directed to a method of installing multiple pedestals at once, onto a pre-marked grid. The pedestal heights are then adjusted with a frame device which is leveled to an "ancillary plane", such that when the floor panels are laid onto the pedestals, the floor is even and level, adjusted for fluctuations in the level of the subfloor.
  • U.S. patent 5,412,914 discloses a raised access flooring system. This system is also primarily designed for office building use or other "commercial" use. Instead of having flat panels placed across pedestals, this invention uses floor “modules” which comprise a "space frame web” of support members upon which is fixedly attached a flooring member or panel. These modules provide the same access to the space between the subfloor and the floor member and are supported by pedestals as are conventional raised access floor systems. However, the space frame web support of the module allows the weight and thickness of the floor member panel to be decreased without a decrease in strength or support. Also cuts may be made in the floor member and space frame web to accommodate installation of "electrical boxes” without compromising the strength of the module to the degree such a cut and removal of a section of floor panel would compromise the strength of prior flooring system panels.
  • U.S. patent 5,440,841 covers a pedestal module for a raised floor, and a raised floor.
  • the floor system disclosed is primarily for use in an office setting. Space is provided between a subfloor and a raised floor in which utilities may be run.
  • the pedestal and raised floor member are all one unit.
  • the pedestal member comprises a flat base with four legs.
  • the units are placed next to each other to create the raised floor.
  • the units are held in place by a pedestal module lock with four hollow, integrally formed leg-receiving apertures.
  • One leg of each of four modules is placed into each module lock to hold the modules together in place.
  • the base portion is also constructed to allow a hole to be cut in its center to receive an electrical connection receptacle.
  • U.S. patent 5,477,649 discloses a raised floor cable trough system.
  • This floor system is also primarily for office building use and is laid over a subfloor.
  • the cable trough system disclosed can be used with new or existing raised floor assemblies which have removable upper floor panels supported at a height above a subfloor by a series of pedestals.
  • the troughs are installed connected to the pedestals and suspended in the space between the upper floor panels and the subfloor.
  • the troughs are also connected to each other such that a network of troughs is formed below the floor panels.
  • Cable or wiring is laid in the trough system such that various groups of cable and wiring can be physically separated from each other, and so that none of the wiring or utilities rests directly on the subfloor to be potentially damaged by water buildup.
  • the troughs are suspended just below the floor panels such that the floor panels serve as the covering for the troughs thus protecting the enclosed wiring and preventing overfilling of the troughs (because the flooring will not lay
  • U.S. patent 5,483,776 discloses a utility floor construction.
  • the floor is designed primarily for office building use, to be laid over a subfloor.
  • the construction includes interconnectable base tiles supported on a floor surface. Each base tile has multiple upstanding pedestals.
  • Floor tiles are then supported on and attached to the pedestals to create a cavity between the base and floor tiles.
  • Various utilities, including wiring for equipment and lighting, and HVAC may then be run in the cavity, and may be easily accessed for repair or modification by removing the upper floor panels.
  • the invention also includes inverted U-shaped "separator channels" to cover and isolate various groupings of wiring laid along the base tiles.
  • the present invention provides an open building flooring system wherein there are substantially three subsystems, a structural subsystem, an interstitial space subsystem and a trim subsystem.
  • the three subsystems inter-relate one to the other in such a manner as to render them substantially integral unto themselves.
  • the interstitial space subsystem is substantially completely disentangled from the structural subsystem and from the trim subsystem.
  • the subsystems more particularly relate to each other in that utilities (heating, air conditioning, electrical, plumbing, communications and the like) may be initially or retrofittingly installed into a building within the interstitial subsystem without altering in any substantial manner either the structural or the trim subsystem.
  • the building flooring system combines two existing types of structural systems; timber joists and light-weight, parallel-chord trusses.

Abstract

Cette invention concerne un système (10) de pose de planchers pour bâtiments, lequel comprend les trois sous-systèmes suivants. Le premier sous-système structurel (8) comprend des poutrelles (12) en bois lourdes et exposées qui sont recouvertes d'entretoises (14) à corde parallèle, légères, perpendiculaires les unes aux autres et cachées. Ces entretoises (14) sont recouvertes sur leurs surfaces supérieures d'un matériau de sous-plancher (24) et possèdent un revêtement de plancher et de finition (24a) disposé sur ce matériau de sous-plancher (24). Un patin de support insonorisant (22) vient calfeutrer les intersections des poutrelles (12) et des entretoises (14) de manière à absorber la transmission du bruit. Le troisième sous-système (6) de type couvre-joint est obtenu en recouvrant la face inférieure exposée des entretoises (14) à l'aide de divers types de panneaux (26) et d'ensembles de couverture des bordures (28). Le second sous-système (30), ou espace interstitiel, se situe entre les caches (24, 26) des cordes supérieures et inférieures (16, 18) des entretoises (14), espace auquel peuvent facilement accéder les premiers installateurs d'équipements tels que des CVC, la plomberie ou les lignes électriques. En retirant les couvertures de bordure (28) et les panneaux (26) sous-jacents, des réparateurs ou des architectes d'intérieur peuvent facilement accéder ultérieurement aux installations existantes ainsi qu'à d'autres zones du bâtiment. Ce système de plancher ouvert permet aux constructeurs et aux propriétaires de dissocier et de séparer la structure du bâtiment des installations de sorte qu'il n'est pas nécessaire de modifier ladite structure lorsque l'on souhaite accéder aux diverses installations ou les modifier.
