EP1602790A1 - Mounting device for conduits and their accessory connected with a joint assembly allowing evacuation and removal of the fluid in case of leakages - Google Patents

Abstract

The support has a parallelepiped shaped main structure with an orifice on four lateral sides and on its bottom. The structure has four upper sides, each of which has a flap (e) that is installed on floor supports. Two split rings are provided to be reversed at 180 degrees with respect to each other. The split rings are adapted to the number of fluid pipings and to the diameters of the pipings.

Description

The present invention relates to a support element for fluid pipelines and their accessories assembled by joints, allowing the evacuation and the elimination of the fluid in case of leaks.

The support of these pipes and their accessories is traditionally carried out using collars, plates, hanging frames, support bars or other means equivalents which, in case of leakage of a part of the joint assembly, leaves the fluid escape into the "environment". In case of leaks, some of these fluids may be a direct or indirect danger to the men operating the industrial site equipped with these joint joints.

The device according to the invention makes it possible to eliminate this danger of environmental pollution. working. It is versatile to different types of piping and accessories making it a standard product. This support device leaves the possibility of making modifications joint joints, at any time, it also allows the latter to be moved or reuse in case of modification of the jointed piping system.

The other advantages of this invention will become apparent with the description and the detailed diagrams that follow.

Figure 6 shows the implementation of the variant shown in Figure 5 on a false floor structure.

Figure 7 shows the insertion on the false floor structure of the flat bottom support member shown in Figure 1.

Figure 8 shows the flat-bottom support member inserted on the false floor structure in place of a slab or slab element.

The device according to the invention consists of a main structure having the shape of a parallelepiped whose upper part is open and whose dimensions are adapted to be embedded in a slab or in a grating (or adjusted to the needs of endorse, of the client): figure 1.

This parallelepiped has, on its four lateral faces as well as on its bottom, an orifice (a) for fixing a connection sleeve (FIG. 3) to a suction system or to a siphon, depending on the nature of the fluid used in the piping.

Only one of the orifices (a) is used to be connected to the exhaust system, the other orifices being either plugged with plates (Figure 4) or used to fix a detection system leaks or an electrical or pneumatic steering system of accessories.

The penetration and the exit of the pipes in the support are carried out in a zone composed of a slot (b) allowing the passage of the pipes and located on two sides opposite of the parallelepiped. To keep in place and in the right position the different pipes, are fixed on the orifices in (c) and in front of the inlet and outlet slot of the piping, two "half shells" (Figure 2) per slot, inverted 180 degrees one by report to the other. These "half shells" can block and maintain the good spacing between the pipes. The use of a joint for this assembly can be necessary to ensure the tightness and / or the good maintenance of the pipes. Figure 2 describes a "half-shell" in an optimal configuration to allow: the entry, the exit and the maintaining twelve pipes with a diameter of approximately 15.5 millimeters. In the case where the number of pipes or the diameter of these would be different from the case presented in figure 2, "half shells" adapted to the number of pipes and the diameters of these are to be expected, on the same principle as the present invention.

An element, called "accessory base", is positioned on the part corresponding to the bottom of the parallelepiped, by means of screws in the positions (d) of Figure 1. The bases accessories, make it possible to fix the pipes and their accessories using systems such as that: screws, clamps, brackets, ..., these "accessory bases" are at number of two. They consist of a rectangle of thickness, width and length adapted to the number and the size of the pipe coming to be fixed on it and includes pre-drilled mounting positions. Between the two "accessory bases" and perpendicularly to these, may be placed under each piping supports ", used to stiffen the piping over the entire portion passing through the parallelepiped in order to avoid deformations and efforts on the joined parts and thus reduce the potential leak.

Depending on the nature of the fluid and the needs of the industrial site, the upper part of the parallelepiped can be closed either by an element making up the pavement in which it is recessed, or by any other removable caulking system supporting, at least, the circulation weight of a person.

In order to allow it to remain in place in the pavement or the grating (FIGS. 8 and 9), the parallelepiped has on its four upper sides, a reference flap (e) of Figure 1 or a lip that comes to rest in turn on the supports of the pavement. This maintenance system place and fixation can have several variants, which will be obvious to men of the job.

A variant of this support with evacuation of the fluid in case of leakage is possible according to the FIG. 5 in the case where the fluids of the various pipes are incompatible in the event of simultaneous leaks. This variant remains on the principle of Figure 1 but consists of two elements of Figure 5, installed face (f) against face (f) as shown in Figure 6, including only the bottom and three sides have an orifice for attaching a sleeve of connection (figure 3) to a suction system or a siphon according to the nature of the fluid used. In this case, two holes will be used to be connected to an evacuation system separate and distinct, the other orifices being either blocked by plates (Figure 4) or used to attach a leak detection system or an electrical control system or pneumatic accessories. The principles of penetration, exit, maintenance and positioning of the pipes remains the same as in the case of Figure 1, only the dimensions of the "half shells" (Figure 2) are to be adapted. It is the same for "Accessory bases" and "support bases".
