Definitions

  • the present invention relates to a method and apparatus in double floors, including an extra or elevated floor carried above the actual floor on a support system of preferably metal posts, for screening the space under the elevated floor from the space above this floor, which is made up from preferably square panels of electrically non-conduc ⁇ tive material with metal cladding on its underside, the panels resting on the support posts at the meeting corners of the panels, the upper sides of the support posts being covered by locating plates made from an elastic non-conductive or partially conductive material and provided with guide means for locating the posts and flooring panels relative each other.

  • the panels which may be lifted individually, are of strong construction and un ⁇ supported between the posts.
  • the carrier plate of each post is covered by a locating plate of elastic material, usually plastics, and is pro- vided with guide means for locating post and panels relative each other.
  • a flange runs round the locating plate to engage against the carrier plate, and on the upper side of the locating plate the guide means takes the form of ridges dividing this side into quadrants for locating the corners of the flooring panels.
  • the locating plates are made from elastic material, usually plastics, in order to take up and compensate for small dimensional differences and possible deformities in the flooring panels.
  • the locating plates are also sound-dampening, for the cases where in spite of all there is play between some panel corner and the underlying locating plate, re ⁇ sul ing in that the panel can move when the floor is wal ed on.
  • the flooring panels which are usually made from an electrically non-conductive building board of some kind, are provided on their undersides with a metal cladding such as aluminium foil.
  • a metal cladding such as aluminium foil.
  • the cladding of all the flooring panels must be electrically connected to each other and connected to ground or earth. As the panels must be individually liftable, it is not possible to arrange connection means under the panels and to connect the panels to each other and to an earthing point with the aid of cabling.
  • Elastic locating plates have therefore come into favour once again to a large extent in the construction of elevated floors, but these plates are now made electrically conductive by mixing into the plastics material powder of a conductive material, preferably carbon.

Abstract

Le but de l'invention est la réalisation, dans des planchers doubles comprenant un plancher surélevé porté par des montants (2) au-dessus du sol proprement dit (1), d'un blindage électrique entre les espaces de chaque côté du plancher surélevé (3). Le plancher surélevé (3) comprend des panneaux carrés de planchéiage (4) reposant par leurs coins en contact sur des plaques élastiques d'emplacement (7) disposées sur les montants (2), les côtés supérieurs des plaques d'emplacement (7) étant divisés en quadrants par des arêtes de guidage (14). En dotant les plaques d'emplacement de lamelles de contact (21, 22), s'étendant depuis les côtés inférieurs des plaques d'emplacement et jusque dans les différents quadrants, on établit une connexion métallique entre les revêtements métalliques (16) sur les côtés inférieurs des panneaux de planchéiage, de manière à former un plan de blindage continu.
