Description

The present invention relates to a fire stop device for the

  caulking an opening, on the one hand, defined at the level of a separating element in the form of a partition, a wall or the like, and, on the other hand, traversed by elements

  through, especially consisting of cables, pipes or the like.

  The present invention relates to the field of manufacturing devices designed to prevent the spread of flames and / or smoke from a fire from one room to another, this through an opening defined at a wall or a partition separating the two premises and allowing the passage of cables, conduits or the like.

  There is already known a fire stop device illustrated in the document W003095757 and which is composed, on the one hand, of an internal frame intended to be mounted inside an opening defined in FIG. a wall and having a plurality of compartments each designed to be traversed by one or more cables or the like and, on the other hand, an external frame, associated with this internal frame, coming to be positioned in front of the the latter and protruding from the wall. This outer frame has several sides reversibly assembled around the cables or the like and is secured to the inner frame or wall.

  This device has a certain number of disadvantages consisting, in particular, in that the internal frame must have dimensions allowing its implantation inside an opening that the wall comprises while ensuring, in an effective manner, a cutting function. -fire in case of fire.

  In order to achieve such an implementation, it is then essential that this internal frame has dimensions substantially adjusted to those of said opening which involves the manufacture, purchase and on-site routing of a plurality of devices dimensions different. In addition and in order to ensure the fire barrier function, it is, moreover, essential to fill a gap remaining between this inner frame and the walls of the opening, including walling.

  Another solution is to choose either a frame with dimensions smaller than those of the opening and to proceed with a masonry around said frame, an internal frame with dimensions greater than those of the opening and to intervene on the masonry to 'widen this opening, or even to build around the frame after its implementation. Whatever the situation, this results in a multiplication of the necessary devices and / or by a number of additional manual operations tedious and expensive.

  Another disadvantage is that this device, more particularly its internal frame, must imperatively be implanted at the masonry before the introduction of cables or the like which are caused to pass through the compartments defined at this frame. This device is suitable, then, in any way, when it comes to caulking an opening already traversed by such cables or the like, for example in the context of the renovation or securing of an existing installation.

  Yet another disadvantage is that, on the one hand, the cables or the like pass through compartments communicating the two premises and, on the other hand, the outer frame includes expansible means only at high temperature and able to close the door. opening of this external frame only in case of fire, so that cold air circulation, fumes or dust is still allowed through this device.

  Finally, this device is designed so that, when the external frame is a separate element of the internal frame, the joining of these frames is performed by welding, riveting or gluing which excludes any disassembly and any intervention on this device after its implementation on site.

  The present invention is intended to overcome the disadvantages of devices of the state of the art through a new firewall device.

  To this end, the invention relates to a fireproof device for sealing an opening, on the one hand, defined at the level of a separating element in the form of a partition, a wall or the like, and on the other hand, traversed by through elements, in particular constituted by cables, pipes or the like, this device adopting the shape of a tubular body having two ends at which this tubular body has an opening intended to be traversed by said through elements extending inside IO of said tubular body. This device is characterized in that the tubular body consists of two complementary shaped tube portions, on the one hand, assembled by means of assembly means that comprises said device, extending from an opening to the other and along said tubular body, and, secondly, immobilized, particularly reversibly, relative to each other through means of immobilization that includes the device.

  According to another characteristic of the invention, the assembly means are constituted, on the one hand, by interlocking means that comprises one of the tube portions and, on the other hand, by interlocking means complementary that includes the other portion of the tube and designed capable of cooperating with said interlocking means.

  An additional feature is that the immobilizing means are of the reversible type and are defined by means of removable type capable of reversibly securing the two tube portions at the level of said assembly means that this tube comprises. .

  Another additional feature consists in that the immobilization means are of the reversible type and are defined, on the one hand, by hooking means that comprise one of the tube portions and, on the other hand, by means complementary hooking means that comprises the other portion of tube and designed adapted to cooperate, reversibly, with said hooking means.

  Yet another characteristic relates to immobilization means of the reversible type constituted by a toggle device comprising, firstly, a first portion secured to a portion of a tube and, secondly, a second portion secured to the another portion of this tube and designed adapted to cooperate with said first portion for the immobilization of these tube portions, relative to each other.

  According to another characteristic of the invention, the reversible immobilization means are completed by means designed to indicate and / or prevent intervention on these immobilization means after assembly and immobilization of the two tube portions.

  An additional feature relates to the fact that the device comprises, internally, means adapted to prevent air circulation through this device, this at least in case of fire, especially for a temperature corresponding to that of a fire .

  Yet another feature consists in that the device comprises, internally, means designed to prevent the passage of this device by particles contained in an air flow, or even by such an air flow, this at least for a lower temperature than a fire.

  Finally, this device comprises means designed to provide protection means to prevent its passage through particles or by an air flow, these means of protection being designed to provide such protection in case of temperature increase , especially in case of fire.

  The advantages of the present invention are that the device can be implanted over cables, pipes or other, while these are already in place at the opening.

  This device can also be implanted at an opening which is in the immediate vicinity of the ceiling, in particular by engaging a portion of tube over the through elements and by sliding over them and in the direction of the separating element.

  Yet another advantage is that the tube portions of this device are immobilized by means of reversible type of means completed by means designed to indicate and / or prevent intervention on these immobilization means, this after assembly and immobilizing the two tube portions.
