Description

DETAILED DESCRIPTION OF THE INVENTION The present invention consists of a duct system joined to a net, and made of plastic or the like (hereinafter referred to as a duct net) (see 1 in FIG. 1). The ductwork (see 1 in FIG. 1) can be mounted with nails, or nail plugs, etc., on the relevant surface.

In areas where there is a risk of clogging of the ducts, the box made of plastic, or other suitable material, made of plastic, or at a suitable mutual distance (see 2 in FIG. 1), is mounted (see I in FIGS. 3 and 1). in FIG. 7) after which the channels thus enclosed are cut off. The mounted box is then provided with a tight-fitting lid (see 2 in Fig. 3) which in turn is provided with a hose, or the like, made of more I or less rigid plastic, or other suitable material (see 3 in Fig. 3). The hose which, if the ductwork is cast or injected with concrete or covered in some way (see 3 and 4 in Fig. 2), forms a connection (see 1 in Fig. 2), in the finished construction, between the ductwork and the free surface, is provided with a band of swelling joint tape, type Quellmax or equivalent, (see 4 in FIG. 3). This is to eliminate any leakage along the hose.

When the ductwork is completely encapsulated, the hoses, or pipes, (see 1 in FIG. 2), which are connected to the ducts, are cut off at a suitable distance from the finished surface.

Then, as required, either a coil device (see 1 in FIG. 4), provided with a non-return valve, or an alarm device (see 1 in FIG. 5 and 1 in FIG. 6) is mounted on the hose, or the pipe.

The alarm device (see in Figs. 5 and 1 in Fig. 6) consists of a movable body provided with O-rings (see 2 in Fig. 5) (see 3 in Fig. 5) mounted in a tube (see 4 in Fig. 5). the movable body (see 3 in FIG. 5) is attached to a stick at one end (see 5 in FIG. 5). When the body, through its connection (see in Fig. 2) with the channels (see 2 in Fig. 2), is subjected to an elevated pressure, of gas or liquid, it is forced to an external position whereby the stick (see 5 in Fig. 5) in its turn is passed out through a smaller opening (see 6 in FIG. 5) and becomes visible.

The landing device can also be supplemented, or only made, with an electrical system that alerts by a plate (see 2 in Fig. 6), mounted on the movable body (see 3 in Fig. 6) in the outer position of the body coming into contact with another plate ( see 4 in FIG 6) mounted in the outer end of the pipe The plates are then connected to an alarm system via wire (see 5 in FIG 6).

Claims (3)

1. 532 38? CLAIMS 1 A system of channels joined to a network (see I in FIG. 1), intended to be mounted on a surface and to be covered with a choice of material (see 3 ooh 4 in FIG. 2), characterized by a network of said, to an interconnected duct system provided with at least one interconnecting box (see in Figs. 3 and 1 in Fig. 7) located at one of the intersection points of the ducts (see 2 in Fig. 1) and where said box is provided with through tubes (see 1 in Figs. 2 and 3 in Fig. 3); intended to form an open connection between the duct system and the free surface of the covering material. A network-connected system duct, according to claim 1, characterized in that at least one of said passage pipes is provided with a coil device (see 1 in FIG. 4). A networked system of ducts, according to claim 10 and 2, characterized in that at least one of said passage pipes is provided with an alarm device (see 1 in FIG. 5 and 1 in FIG. 6) for indicating elevated liquid and or gas pressure.
