Description

The present invention relates to an all-height vertical duct path for the mechanical support and the ducting of the electrical ducts of the various constituents. DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE ELECTRICAL AND / OR SANITARY FLUIDS ensuring the distribution of primarily electrical energy in a collective or individual residential dwelling. In the art of the present technique, a box-type box or box with an opening on the user side is set up to receive the electrical functions. This tray or cabinet is installed after the partitioning of the different areas of life of the tray, entrance, kitchen, rooms in this current technology, it is therefore necessary to make cuts in the drywall constituting the partitions separating the living areas.

This method of anachronistic intervention in the state of construction handicaps the planning and the cost of construction, while obscuring the advantages of the proposed solution of the duct path described below. This all-height one-piece duct path is of the U-shaped channel type linking the floor to the ceiling and having a front face any height open to the user in the room where it is implanted. The two side flanks are integral with the rear background in all height also. The lower part of this duct path is fixed to the floor of the floor or low slab and the ceiling or high slab of the residential plateau passing the electrical conduits by channeling in its U-shaped profile, electrical conduits from the high or low slab. Fixing this duct path is carried out in its bottom and bottom without bottom by dowels and screws through a splice or gusset in its upper part this duct path has longer screws allowing a possible adjustment to to compensate for and adapt to the small differences in the height standard between the floor and the ceiling, or low and high slab, deviations due to masonry tolerances. This duct path, or chute height is a U-shaped envelope, it is intended to channel the electrical conduits from the floor and the ceiling and to receive the various electrical components necessary for the distribution of electrical energy for different functions as well as the protection devices defined by the standard for strong currents, and the comfort of people in terms of low current, television intercom, optical fiber, protection against intrusion. The number and diversity of different high current and low current functions are related to the surface of the habitable residential plateau, the desired comfort, electric shutters, air conditioning, the type of heating, electric, gas. With this monoblock duct path any height attached to the ground or low slab and ceiling or high slab, both generally concrete, this duct path offers a wide variety of opportunities and possible electrical compositions required by the standard. The duct path system requires a single reference. Normally this system is identified by art professionals, standardizers, installers and controllers, under the name "GTL or Housing Technical Sheath".

Standardization, and electrical power distributors consider three areas in this GTL. These three zones are substantially equal, and must be visible and permanently accessible during the life of the installation. - the top third must be visible, but too high to be usable, otherwise for weak currents, box, not very practical ... the standard leaves the choice to the installer, we will see below that in the context of the invention, this top third will be used in the construction phase of electrical distribution of living areas housing - the middle third is imperatively dedicated to strong currents, sockets, switches, etc ... due to normative constraints related to different heights breaking devices such as circuit breakers, among others for persons with reduced mobility, this area must be accessible and must not include a lock in the door giving access. - the bottom third is generally dedicated to the weak current, television, box, video doorman, optical fiber. Its volume becomes more and more important with the evolutionary and intelligent house, we will see below the gradation in the various services offered by the manufacturers of electrical equipment and the proposals of the builders promoters. It should be noted that the low current portion must not be subjected to the Faraday cage because of the WIFI radiation of the box, the current products of the tray type are made of solid plate, and closed by a solid metal door. , which constitutes a perfect cage of Faraday. As specified below, the duct path according to the invention is made of metal son and not of solid sheet, son welded together horizontally and vertically forming a wired frame constituting a weak screen electromagnetic waves, the reason being to promote a better propagation of WIFI waves in the living area. According to the invention, the one-piece duct or duct path for the ducting of the electrical ducts and the mechanical support for the protection of the devices ensuring the distribution of the electrical energy of a residential plateau defined above is characterized by the fact that: this duct path is monobloc between the floor where the low slab and the ceiling where high slab, coming to accommodate the bundles of electrical ducts from the floor or ceiling, - variable width and depth in its U-shaped profile to meet the residential floor surface requirements to be equipped, as standard, - to provide full and perfect floor-to-ceiling accessibility in accordance with the power standards prior to the circuit breaker, distributor's terminals electrical energy and after the terminals of the user's circuit breaker, and the control body of the installation, - that the installation and fixing of this emin of sheaths are put in place on a virgin board before all divisions and distribution of the different zones life, kitchen, entrance, rooms, stay, etc ...

The implantation of the duct path is done after the concrete formwork removal of the high slab, where all the electrical ducts come out in a bouquet generally from the high slab. - The establishment and fixing of this conduit duct path, or chute height from floor to ceiling are made with dowels and screws low slab through splint or gusset on the positioning defined by the position of exit of the electrical ducts on the bare residential plateau, after dismantling concrete of the structural work of the high slab or ceiling, and this well before the division of the different livable surfaces, kitchen, entry, rooms, etc ... - the high and low ducts are then protected, by said duct path, shocks site, or even possible breakage of the ducts resulting in heavy and expensive interventions, the entire monobloc duct path acts as a bumper for duct bundles coming down from the ceiling , or up from the ground. - It should be noted that the electrical sheaths generally come out of the ceiling or high slab, where is the heart of the electrical distribution strong current, and low current, usually 22 to 50 electrical sheaths of different diameters generally used for a Electrical Installation.

The positioning of these electrical sheaths is performed before concrete pouring of the high slab. When the forms are removed, the bouquet of ducts leaving the ceiling will remain apparent. This duct path is implanted before any distribution of life zones, it can receive advantageously in the upper part of the duct path, a temporary electrical function called temporary building kit necessary for the various trades involved to benefit from the electrical energy, drills, sanders, light etc ... It should be noted that the manufacturer specific envelopes that we call subscriber table are characterized by horizontal parallel rows of 13,18, and 24 modules of 1 to 6 vertical rows. The low current portion, telephony, box, video doorphone etc ... consists of a distribution generally provided by brewing bays and depending on the complexity required, the professional will install boxes of grade 1,2,3 or 4 in envelopes of more or less important protection depending on the grade, the grade defining the number and complexity of possible functions. The implementation of these two functions in independent cabinets is carried out on wood cleats, parallel in vertical two or four, depending on the configuration of the installation, cleats running over the entire height of the duct path, from floor to ceiling.

These cleats are fixed by clipping on the bottom of the U-shaped cladding path opposite the opening. These cleats are offset from the bottom to the front face a few centimeters, generally so as to cross, overlap, at the rear of said cleats, at least two electric sheaths of larger diameter.

The space left between the bottom of the duct path and the cleats provides a capacity and ease of wiring for the professional. These cleats receive the chassis of the electrical boxes by means of wood screws for their fixation.

As a variant of use and instead of the cleats running the entire height of the duct path, the bottom of the U of the duct path can receive trays or traditional boxes of different sizes attached to the bottom of the U to receive themselves the different electrical functions high current or low current.

As a variant, this one-piece high-duct duct may receive other fluids such as copper ducts or P.E.R. ducts for sanitary purposes for dispensing and supplying hot water, cold water for the platform to be equipped. It should be noted that the same duct path can distribute electrical energy on one of its faces, and on the same duct path, but at the rear, distribute the sanitary hydraulic energy and the boiler gas. This duct path could then be called all fluid technical sleeves ... The invention consists, apart from the provisions outlined above, a number of other provisions which will be more explicitly discussed below about of an exemplary embodiment described with reference to the accompanying drawings, but which is in no way limiting.
