Description

Conduit for electrical cables with a band or built-in plaster strip.

Scope and prior art

The invention has application in construction  of buildings, more particularly for the placement of cable ducts on cross-linked floor slabs and roofs

Cross-linked slabs from time to time used instead of traditional slabs do not allow the realization of rubs for embedding of pipes or conduits for electrical wiring.

With reticulated slabs are used conduits for flat cables that must be attached to the floor for the subsequent application of the plaster covering the entire surface of the floor, including installed cable ducts.

With this technique it is inconvenient to that to facilitate the application of the plaster, the ducts for cables must be fastened beforehand, at least provisionally, when forged by nails or staples that can damage the cables electrical housed inside. In addition, it also turns out inconvenient that plaster, for example, plaster, cement, etc., applied on the floor and covering the cable ducts, when it sets, it tends to crack in the areas adjacent to the cable ducts.

Object of the invention

Starting from the prior art  described, the object of the invention is the development of a conduit for electrical cables that allows to solve the issues raised.

According to the invention, this objective is achieved through the features of claim 1. Other advantages of the invention result from the characteristics of the dependent claims.

According to the invention, the conduit for cables are characterized in that said conduit comprises:

-

a duct body, general configuration in the form of parallelepiped, with a plurality of channels to accommodate cables electrical, and that has a surface to fix to the floor and a free surface on which the plaster is applied; Y

-

a plaster band or strip based on mesh material that is adhered to the free surface of the duct body forming a all with said duct body.

According to the invention, the band or strip of plastering is made of a thermoplastic mesh or fiber material glass.

Advantageously, the duct body for cables and the plaster strip or strip are attached by bonding with adhesive or by ultrasonic welding.

Brief description of the drawings

Other features and advantages of the invention  will result more clearly from the description that follows with the help of the attached drawings, referring to an example of non-limiting execution and in which:

Figure 1 shows a perspective view of a cable conduit according to the invention.

Figure 2 schematically illustrates the cable duct placement according to the invention applied on a floor and covered by a layer of plaster.

Detailed description of a preferred embodiment

As can be seen through the drawings, the cable duct according to the invention, generally designated by numerical reference 1, it consists of a duct body 2 and a band or strip of mesh material 3 adhered thereto for form a whole

The duct body 2 has a configured plurality of channels 20, 21, 22 for cable routing C. This duct body 2, with general shape of parallelepiped, has a first surface S1 to fix to a reticulated forging F of a floor or ceiling of a building and a second free surface S2, on which the plaster E is applied, for example plaster or cement of the ceiling or floor.

Thanks to the mesh material adhered to the free surface S2 of the duct body, when setting the plaster E applied to the floor F, the appearance of cracks does not occur due to the different characteristics of the plastic material of the duct and plaster.

In addition, since the band or strip 3 extends  throughout the length of the duct body, the holes of its mesh material, serve for the collation of elements 4 of fastening, such as nails or staples, to floor F to application of plastering E, avoiding the possibility that stabbing fasteners may damage electrical wires housed inside the duct.

Enough that the object has been described of the invention, it only remains to point out that the embodiments derived from changes in shape, dimensions and the like, as well as those resulting from a routine application of the above disclosed, should be considered included in its scope, so that the invention will only be limited by the scope of the following claims.

Claims (3)

1. Conduit for electrical cables with a built-in plaster strip or strip, characterized in said conduit (1) because it comprises:

-

a duct body (2), of general parallelepiped configuration, with a plurality of channels (20, 21, 22) to accommodate cables electrical (C), with a surface (S1) to fix to a floor (F) of a roof or of a floor and a free surface (S2) for plaster application (E); Y

-

a plaster strip or strip (3) based on mesh material that is adhered to the free surface (S2) of the duct body forming a whole with said duct body.

2. Conduit for electrical cables with a plaster strip or strip incorporated according to claim 1, characterized in that the plaster strip (3) is made of a thermoplastic mesh or fiberglass material. 3. Conduit for electrical cables with a plaster strip or strip incorporated according to the preceding claims, characterized in that the cable duct body (2) and the plaster strip (3) are joined together by adhesive or adhesive ultrasonic welding.
