Abstract

A sleeve fastening system fastened to a joist pierced with a hole and receiving two pipes and including a cylinder fitted into the hole of which each end receives a pipe, wherein the wall of the cylinder has cut into it at least one tunnel, a flange, each tunnel having openings that emerge on either side of the flange that has a bearing face bearing against the joist and a free face, and for each tunnel, a holding system having a link, a shoe and a locking system, the link being housed in the tunnel with the shoe blocked in a first opening on the side of the free face and wherein the link exits via a second opening on the side of the bearing face and wherein the locking system attaches.

First claim

The invention claimed is:

1 . A sleeve fastening system for fastening to a joist pierced with a hole and to receive two pipes, the sleeve fastening system comprising:
a cylinder of which each end is configured to receive a pipe by fitting, wherein a wall of the cylinder has cut into the wall at least one tunnel that is sealed with respect to an inside of the cylinder, wherein the cylinder is configured to be fitted into a hole in the joist; a flange as one with the cylinder and extending around the cylinder, wherein each tunnel has a first and second openings that emerge outside the wall of the cylinder and on either side of the flange, wherein the flange has a bearing face to bear against the joist and a free face opposite; and for each tunnel, a holding system having a link, a shoe as one with a first end of the link and a locking system, wherein the link is housed in the tunnel such that the shoe is blocked at the first opening that is on a side of the free face and such that the second end of the link exits via the second opening on a side of the bearing face and wherein the locking system has a connector that attaches to the second end of the link and a bearing surface to come to bear against the joist.

2 . The sleeve fastening system according to claim 1 , wherein the cylinder bears a bypass pipe that is on a side of the first opening with respect to the flange and that emerges inside the cylinder.

3 . The sleeve fastening system according to claim 1 , wherein the link comprises a self-locking clamping collar with teeth and wherein the connector has a non-return ratchet that cooperates with the teeth to block withdrawal of the link.

4 . The sleeve fastening system according to claim 3 , wherein the ratchet is mounted on an elastic arm of the connector.

5 . The sleeve fastening system according to claim 1 , wherein the holding system has a support that extends the bearing surface towards the flange and is configured to penetrate into the hole, passing between a roof of the tunnel and a surface of the hole.

6 . An assembly comprising:
a joist passed through by a hole; two pipes; and a sleeve fastening system according to claim 1 wherein the cylinder is fitted into the hole and the bearing face of the flange bears against the joist, wherein the bearing surface is against the joist, and wherein a pipe is fitted onto each end of the cylinder.
