Abstract

Conduits for ducts or junctions in services distribution systems for buildings, etc. are assembled from complementary panel profiles made of polymeric materials, esp. PVC, to form the walls (1), cover (3) and opt. base (c) components of square or polygonal section ducts. The edges of the wall panels pref. are stepped to provide complementary semi-interlocking head-to-tail coupling at the intersections of the wall panels. The corners may have external ribs to key the ducts into a surrounding structure. The wall panels pref. also feature a series of concentric circular ribs linked by thin wall zones (1a) to conveniently accept any one of a variety of spigot end sizes of conduit for which the ducts can serve as junctions. Pref. the upper and lower rims of the wall panels are stepped (1f,g) to permit stacking for construction of vertically extended ducts. The interior surfaces of the panels may have ancillary ribs (14) for locating internal baffles, grills, seals etc.

Description

The object of this patent application for industrial utility model is a well by elements, made of PVC or other polymeric materials, to be used in the building industry and in particular in urbanization works.

Today to provide the connection and connection of electrical lines, telephone or sewer lines we use wells obtained through a concrete pier, and closed above, as the case may be, by grids or by covers.

On the sides of these wells, openings must be left to allow the pipes traversed by the sewage, or which contain telephone or electrical cables, to lead into the interior of the well.

Depending on the number of pipes that must be connected, it is however necessary, each time, to provide an adequate number of holes, with suitable diameters, on the side walls of the concrete well.

It is easy to understand from this perspective that building wells on site will be particularly costly, since provision must be made for the provision of suitable formwork, preparation and pouring the concrete, the period of time necessary for the concrete to wipe and harden; but we can also understand, on the other hand, that it would also be disadvantageous to use prefabricated concrete wells and carried to the place of installation, especially considering the difficulties that arise from transport because of their weight and their bulk.

The well made of PVC or of other polymeric materials according to the invention was designed precisely to overcome the drawbacks denounced by concrete wells, aiming, on the one hand, for the production of a product capable of giving the same garancies of operation of the wells used until now, and, on the other, seeking to attribute to it, compared to these, qualities of versatility and economy far superior.

In fact, it consists of four side walls made of elements made of PVO or other polymeric materials to be embedded and glued together to make them waterproof, closed below by a bottom and above by a cover or by a grid, also in PVC or in other polymeric materials, so that the invention, when the assembly is finished, must appear externally like a cube and that one can in this way put it in works very easily.

The fact that each side of it is stamped, in PVC or in other polymeric materials, for injection with an interlacing of ribs, gives the invention a more than sufficient robustness, if we consider the use for which she is assigned, while, at the same time, the equipment with which the well is co _n - struit, it is able to ensure absolute resistance to the corrosive action of sewage and wastewater that must sometimes contain.

However, the fact remains that the well can boast really considerable qualities of lightness, which we cannot even compare to those of concrete wells and that our well, therefore, in relation to these, can be transported and installed much more easily.

Another peculiarity of the invented well is that it, when it is devoid of the bottom and the cover, can be stacked with others, and this, if on the one hand allows easier installation of the wells during transport and storage , on the other considerably amplifies its functional quality, making it possible to easily obtain, during installation, wells having multiple heights.

As regards moreover the possibilities of connection or connection. With sewer, electricity or telephone lines, it must be said that on the sides of the well in question there are provided four concentric circular imprints of different diameters, which circumscribe as many zones of the breaking pin, which can, if necessary, be easily undone without compromising in any way the integrity of the rest of the surface on the side itself, in order to obtain a hole in which we will fit a conduit d 'any of the measures which are generally employed for works of urbanization.

In case the well according to the invention should be em _- bent in a sewer pipe, it has also been planned that the latter, in order to avoid the spread of bad odors, is siphoned off with a dividing system on the outlet hole, in case it is closed above by a airtight lid, or with a bell siphon, if a grid has been provided for the top of the well.

• - Fig.11 is the section with the plane BB of Figure 5.

Referring to the aforementioned figures, the well according to the invention, the assembly completed, has an almost cubic shape, obtained by the union of four side walls (1), a bottom bottom (2) and an upper cover (3) which can be replaced, if necessary, by a grid.

The side walls (1), both identical, are provided with their four sides of the same dimensions; each of them, on its outer face, not only has median stiffening profiles, but it also has a central zone (1a) characterized by the presence of four concentric circular ribs of different diameters, which circumscribe as many thinned zones d 'rupture pin which must be undone, each time, according to the diameter of the tube which must be introduced into the well.

The side walls (1) are joined to each other through the use of suitable adhesives, but it should be added that, to allow perfect reciprocal assembly, these side walls (1) have rounded side edges of 45 ° (1b).

To promote and center the embedding of the side walls (1) on the edges rounded at 45 ° (1b) of each of them, provision has been made, on the one hand, for three protruding reliefs (1c) and, on the other , three corresponding conforming housings (1d) intended respectively to interlock with as many other housings and with as many other reliefs provided in the rounded edges (1b) of the adjacent side walls (1).

In correspondence with the lateral edge (1b) on which the housings (1d) have been provided, each of the walls (1) has a longitudinal outer edge (1e) which has the role of covering and permanently sealing the slot which derives from the union with the adjacent wall.

It should also be added that all the lateral edges (1b) have at their lower end a small step (1f) in order to be able to obtain, once the four lateral walls (1) are joined to each other, a section of narrowed base that we will stick and embed exactly in a bottom (2) in the square plane, provided, along its entire perimeter, with a groove (2a) which has the role of containing the aforementioned narrowed section and also provided raised edges (2b) intended to surround it exactly.

When you want to obtain a well of a multiple height, the basic narrowed section, instead of being embedded in the edges of a bottom, is threaded exactly and glued between the upper edges of the four walls (1) d 'in other wells, which have an adequate support step (1g) addressed inwards.

Above the side walls (1) we will place a square cover (3) with the right dimensions which presents below a skirt (3a) intended to engage exactly, for a safer installation, inside. laughing at the upper ends of the walls (1), but which is, in any case, screwed thereto in order to be able to fix it securely.

It must also be said, for use of the well having the function of a connection for the sewer pipes, that on all the internal faces of the side walls (1) pairs of ribs (1b) are provided acting as guides longitudinal in which we will introduce and support a valve in PVC or other polymeric materials and this, by dividing the well into two adjacent watertight chambers, allows passage over the bottom of the sewage while preventing return smelly gas.

In this connection, it should also be added that, in case, on the contrary, we want to place a drain grid above the well in place of the airtight cover, inside the well, a siphon must be provided. with bell.

It is almost useless to add that, while remaining in the same inventive field, it will be possible to obtain wells, with the same functional characteristics as that which we have just described, which do not necessarily have a plan square, but any other polygonal shape too; in this regard it will suffice to combine a corresponding number of side walls, having rounded side edges so as to be able to be effectively joined together, a cover and a bottom of just conformation.
