Abstract

An improved coupling assembly (10) mounted on a corrugated deck (30) and embedded in a concrete partition, such as floor (100), to provide an opening through the deck and the floor, is described. The coupling is comprised of an inner conduit (13) mounted inside of an outer sleeve (11). A flange portion (15) is provided at one end of the sleeve and includes openings (19) for fastening means, such as nails or screws (21) that serve to secure the coupling assembly in position on the deck. The conduit is mounted to the inside (11A) of the sleeve to position the opposed open ends (13B) and (13C) of the conduit extending beyond the sleeve means and through an opening (50) in the deck. The sleeve enables the contact point between the sleeve and the conduit to be adjusted along the length of the conduit. This is useful in those situations where the conduit has been mounted in an existing building construction or where the mounting position between the conduit and sleeve needs to be adjusted. The coupling is then embedded in the poured concrete floor and fluid carrying pipes can be connected to the opposed open ends of the conduit. The partition need not necessarily be a floor, but instead can comprise a wall. The floor can also be sloped and an upper end of the conduit can be provided with a drain conduit (61) for removing liquid from the top of the sloped floor.

Dependent claims

A fitting assembly adapted to be secured to a deck means comprises of alternting side-by-side ridge and valley portions providing a corrugated shape and wherein the fitting assembly serves for carrying a fluid through an opening in the deck means, which comprises:

(a) a sleeve means having an outside sidewall between opposed open ends and an inside sidewall providing an opening along a longitudinal axis of the sleeve means and with an annular ring around the outside sidewall of the sleeve means;
(b) an attachment means extending from the sleeve means away from the longitudinal axis, wherein the attachment means serves to secure the sleeve means to the deck means mounted on an apex portion of at least two spaced apart ridge portions or valley portions of the corrguated deck means;
and
(c) a fluid carrying conduit means adapted to be mounted through the opening in the sleeve means and through the opening in the deck means and to extend above the sleeve means so that concrete can be poured around the conduit means, the sleeve means and the attachment means above the deck means to embed the fitting assembly in the concrete wherein the fluid carrying conduit means is comprised of an outside sidewall secured to the inside sidewall of the sleeve means wherein a diameter of the outside sidewall of the conduit means is only slightly smaller than a diameter of the inside sidewall of the sleeve means and an inside sidewall between opposed open ends defining a second opening through the conduit means for carrying the fluid and the conduit means having a length so that the outside sidewall of the conduit means is able to be adjustably mounted along the inside sidewall of the sleeve means to adjust a distance between one of the opposed open ends of the conduit means and one of the opposed open ends of the sleeve means and wherein the opposed open ends of the conduit means extend through the opening in the deck means to provide for carrying the flid through the deck means.

A method for connecting a fitting assembly through an opening in a deck means comprised of alternating side-by-side ridge and valley portions in a corrugated shape, wherein the fitting assembly serves to carry a fluid through the opening in the deck means, which comprises:

(a) providing the fitting assembly, which comprises:
a sleeve means having an outside sidewall between opposed open ends and an inside sidewall providing an opening along a longitudinal axis of the sleeve means and with an annular ring around the outside sidewall of the sleeve means;
an attachment means extending from the sleeve away from the longitudinal axis, wherein the attachment means serves to secure the sleeve means to the deck means mounted on an apex portion of at least two sapced apart ridge portions or valley portions of the corrugated deck means;
and a fluid carrying conduit means adapted to be mounted through the opening in the sleeve means and comprised of an outisde sidewall secured to the inside sidewall of the sleeve means wherein a diameter of the outside sidewall of the conduit means is only slightly smaller than a diameter of the inside sidewall of the sleeve means and an inside sidewall between opposed open ends defining a second opening of the sleeve means for carrying the fluid and the conduit means having a lenght so that the outside sidewall of the conduit means ia ble to be adjustably mounted along the inside sidewall of the sleeve means to adjust a distance between one of the opposed open ends of the conduit means and one of the opposed open ends of the sleeve means and with the opposed open ends of the conduit means extending through the opening in the deck means;
(b) providing the deck means having the opening and securing the sleeve means to the apex portions of at least two sapced apart ridge portions or valley portions of the corrugated deck means by the attachment means so that the inside sidewall of the sleeve means ia aligned with the opening through the deck means;
(c) mounting the conduit means inside the sleeve means with the outside sidewall of the conduit means secured to the inside sidewall of the sleeve means and with the opposed open ends of the conduit means extending through the opening in the deck means and beyond the opposed open ends of the sleeve means to provide for moving a fluid through the conduit means and through the opening in the deck means;
and
(d) pouring concrete around the outside of the conduit means, sleeve means and attachment means above the deck means to provide the assembly for moving the fluid through the conduit means.
