Abstract

Said assembly comprises a base body (2) and several different adapters (3), one of which is inserted, in a sealed manner, in a recess (21) of an end wall (12) of said body (2). The adapters (3) have a surface (36) for supporting a projection of a flow member. The bearing surfaces (36) have different heights (45), depths (37) and / or widths, so that differently tall or wide flow elements can be connected to the same base body (2 ).

Description

MODULAR ASSEMBLY FOR DRAINAGE CHANNELS

WATER FLOW

  The present invention relates to a modular assembly

  re for an inlet or outlet drain of a drainage channel-

  water, consisting of several channels which

  are aligned with each other and have a high

  gradually increasing. Drains of water drainage channels are known per se. They have relatively thin walls,

  are rectangular and open upwards. The side walls

  Rales have internally, in the upper part, a step extending longitudinally to give support to a

  grid or grid frame. The extreme walls are per-

  cées of recesses in which the end of an element of ri-

  gole can be inserted. The water drainage channels are assembled from channel elements whose height

gradually increases.

  The object of the present invention is to provide a set of

  modular ble for gullies of water drainage channels, which allows the rational use of a channel element

  and its connection with liquid tightness.

  In accordance with the invention, this object is achieved by the

  fact that the modular set includes a basic body and more

  adapters, the base body being provided with two parallel side walls, two end walls and a bottom, at least one of the end walls having a recess in

  which one of the adapters can be inserted tightly

  che; by the fact that each adapter has a surface giving support to a projection of the channel element; and by the fact that the height of the bearing surface, measured from the underside of the adapters, and / or the width and / or the depth of the bearing surface is (are) different among the various adapters of the modular assembly, so

  that differently tall and / or differently

  wide can be integrated by coming flush with the

same basic body.

  According to other advantageous features of the invention,

  note: - each adapter preferably has, at the bottom, an approximately rectangular body, from which stands a narrow plate provided with a notch configured in U and open upwards; - the bearing surface of at least some of the adapters can, conveniently, be wider than the projection of the elements

  channel, so that when the channel element is integrated

  optionally, a groove in the shape of a U seen at the end, designed to be filled with a sealing mass, is formed between the front face of the projection and the surface of the plate which is turned towards said front face;

  - said bearing surface can advantageously be trapezoidal

  dale; - preferably, the underside of each adapter and

  the recess respectively have a step, said gra-

dins cooperating with each other;

  - a sleeve, embedded in the base body, can be useful -

  provided with an external flange located at a distance from the

  internal frontal moth; - A sealing ring made of an elastomer, applied against the flange, is preferably embedded together at least on one side of said flange; and - the sleeve can advantageously consist of a plastic material.

  The fact that the modular assembly includes adaptations

  teurs of different heights allow flush connection,

  at the same basic body, a flow element of high height

  playable. This makes it possible to use, on short segments of

  gutters, flow elements consequently less elevated

  which reduces structural and material complexity. Just make and store a basic body type, this

  which lowers production and storage costs.

  The invention will now be described in more detail,

  title of example in no way limiting, with regard to the drawings an-

  attached in which: FIGS. 1 and 2 are perspective views illustrating, respectively, the individual parts or the completed drain; Figure 3 is a longitudinal section of the drain to which a channel element is connected; and

  Figure 4 is a section through a sunken sleeve.

  A drain 1 consists of a basic body 2 made of concrete at

  polyester, as well as an adapter 3 which preferably consists of

  It also uses polyester concrete and is designed for

  connection of a channel element 4 of a drainage channel

  waters. The base body 2 is rectangular, is open upwards and comprises two side walls 11, two end walls 12 and a bottom 13. The walls 11 and 12 may include

  pre-cuts 14 of programmed rupture, having a diameter

  tre or a different shape (e), which allows to knock, in a selectable location, an insertion opening of a

  connection sleeve. A sleeve 15 can be rigidly embedded

  ment in one of the walls 11, 12. The sleeve 15 has, at

  tance of its internal front end 16, an external flange 17 embedded by concordance of shapes in the concrete of the body 2. A

  O-ring (sealing ring made of an elastomer) 18, applied

  qué against the flange 17 and jointly drowned at least on one side,

ensures a tight connection.

  The end walls 12 are pierced with a recess

  pectif 21 of rectangular shape, open upwards. The lar-

  gor 22 of this recess 21 corresponds to the width of a sail-

  lie 23 of the channel element 4, showing a narrowing in shape, and is greater than the inner dimension of the base body 2 between the side walls 11. The depth 25 of the recess 21 corresponds to the thickness of the 'adapter 3. The recess 21

  has a step 24 in the lower part.

  The adapter 3 comprises, in the lower part, an approximately rectangular body 31, the lower face 32 of which has a step 33 complementary to the step 24. A narrow plate 34, rising on one side from the body 31, is provided with 'A notch 35 configured in U, open upwards and whose cross section corresponds to the internal cross section of the channel element 4. Between the plate 34 and the end face of the adapter 3, the body 31 is provided

  a surface 36 of trapezoidal shape observed at the end,

  rant a support to the projection 23 of the element 4. The depth 37 of the support surface 36 is greater than the width 38 of the projection 23; when inserting element 4, this gives

  birth, between a front face 39 of the projection 23 and the sur-

  face of the plate 34 which faces towards said front face

  the, to a groove 40 of rectangular cross section, coated

  both the shape of a U observed at the end, and whose sealing is ensured by means of a sealing mass 41. The element 4 is thus connected to the drain 1 with liquid tightness. At

  At the assembly stage, the adapter 3 is also embedded in the

  21 using a sealing means such as, for example,

  polyester. This provides a very good seal

cheerfulness.

  The modular assembly intended for the realization of the ava-

  dormouse 1 includes, in addition to the base body 2, several adapters 3 whose bearing surface 36 has a different height 45

  measured from the underside 32, in a corresponding manner

  laying at the different height of the flow elements 4. It

  Each time, the adapter 3 is fitted.

  required, so that an upper edge 46 of element 4 comes to

  flower of an upper edge 47 of the base body 2.

  Due to the fact that several different adapters can be integrated, the same basic body 2 can be used for the connection of differently tall channel elements 4. This has the effect of reducing the production and storage costs of

have it 1.

  As a variant or in addition, the modular assembly can also

  ment present adapters 3 whose bearing surface 36 is differently wide and / or differently deep. When, for example, the seal provided by a sealing mass 41 is not necessary, the depth 37 can be chosen equal to the width 38 of the projection 23. When it is advisable to connect channel elements 4 plus narrow, the adapter 3 can be made so as to receive the projection 23 consequently more

  narrow. These modifications concern, each time, only-

  The adapter 3 can be produced in a simple and inexpensive manner, so that the basic body 2, which is more complicated, can be used for multiple applications and can, in addition

  consequently, be produced rationally in large numbers.

  It goes without saying that many modifications can-

  can be made to the modular assembly described and represented

  without departing from the scope of the invention.
