Abstract

A nuclear facility comprising an anchor device is provided. This anchor device comprises a female part and a male part. The female part includes a groove extending along a longitudinal axis. The groove has a width which decreases longitudinally and a transverse section. The male part includes a slider with a shape mating that of the groove and is able to be longitudinally inserted into the groove. The transverse section of the groove is configured so as to prevent the extraction of the slider out of the groove transversely to the longitudinal axis. The anchor device includes a locking device able to prevent the slider from longitudinally sliding out of the groove.

First claim

What is claimed is:

1. A nuclear facility comprising:
a pool filled with water; and
at least one anchor device, each of the at least one anchor device including a female part and a male part, for each of the at least one anchor device:
one of the male part and the female part being attached onto an internal wall of the pool, the female part including a groove extending along a longitudinal axis, the groove having a width longitudinally decreasing from a first groove end to a second groove end and a transverse section, the groove being laterally delimited by two side walls facing each other, the side walls extending along the longitudinal axis while converging towards each other from the first groove end to the second groove end, the groove opening out perpendicularly to the longitudinal axis through a longitudinal aperture delimited between free edges of the side walls, the male part including a slider with a shape mating that of the groove and able to be longitudinally inserted into the groove, the transverse section of the groove being configured so as to prevent extraction of the slider out of the groove transversely to the longitudinal axis,

each of the at least one anchor device including a locking device able to prevent the slider from longitudinally sliding out of the groove.

2. The nuclear facility as recited in claim 1 wherein for each of the at least one anchor device the transverse section of the groove has at least one dovetail.

3. The nuclear facility as recited in claim 1 wherein for each of the at least one anchor device the locking device includes at least one locking screw.

4. The nuclear facility as recited in claim 3 wherein for each of the at least one anchor device the at least one locking screw is rotatably mounted on one of the female part and of the male part, the other one of the female part and the male part including a tapped hole for receiving the locking screw.

5. The nuclear facility as recited in claim 4 wherein for each of the at least one anchor device the at least one locking screw is mounted so as to be captive on one of the female part and of the male part.

6. The nuclear facility as recited in claim 1 wherein for each of the at least one anchor device the male part includes a lumen extending through the male part through the slider so as to define an internal edge for attachment of the male part through the slider.

7. The nuclear facility as recited in claim 1 wherein for each of the at least one anchor device the locking device includes a locking portion added to and attached onto the male part, the locking device being provided for retaining the female part on the locking portion.

8. The nuclear facility as recited in claim 7 wherein for each of the at least one anchor device the locking portion is attached onto the male part by at least one key.

9. The nuclear facility as recited in claim 1 wherein each of the the at least one anchor device includes a guiding device for guiding the slider when longitudinally sliding in the groove before the slider is engaged with the side walls of the groove.

10. The nuclear facility as recited in claim 9 wherein for each of the at least one anchor device the guiding device includes a guiding protrusion on the one of the female part and of the male part and a guiding orifice on the other one of the female part and of the male part, the guiding orifice receiving the guiding protrusion during longitudinal sliding upon inserting the slider into the groove.
