FR2483563A1 - Tube or pipe clip - has flexible segment attached to base by stud under segment - Google Patents

Abstract

The pipe clip consists of a base cylinder (3) with a flat base, so that it can rest on a support plate (1). The plate has a number of holes (3). The lower part of the cylinder has a pin (7) with an expanding head (8) which can pass through the hole in one direction. The pipe (6) is held in an integral segment (5) which sits on the top of the base cylinder. The opening of the segment is 110 deg. and the inner radius is equal to the outer radius of the pipe.

Description

clip system for tubes, pipes or the like.

The present invention relates to a clip system for tubes, pipes or the like. In particular, the present invention relates to a tube clipping system used mainly in devices for heating and cooling surfaces such as walls, ceilings or floors.

Air conditioning devices of this type are mainly constituted by a network of tubes distributing the heat fluid which is mounted in the form of a coil against a support layer. Most often the support layer which can be constituted by insulating plates, is provided with a network of grooves which determines the arrangement of the heating tubes in the laid state. However, in certain methods of installing such air conditioning devices, the network of tubes is fixed directly against the support layer. In general, the network of tubes thus positioned is covered with a covering layer such as a layer of concrete or the like which keeps it in place. It is however necessary to at least partially fix the network of tubes in order to avoid any displacement of these during the installation of the coating layer.

So far we have proposed various attachment systems to fix the tubes in position before drowning in the coating layer. For example, a fastening system is known which consists in coating the entire surface of the support layer with a trellis and in fixing the tube to the trellis by means of any known fixing device such as wire, twine and the like. Such a system has many drawbacks. It requires a large trellis surface, which increases the cost. On the other hand, it is necessary to carry out complicated measurement and alignment operations in order to obtain correct positioning of the network of tubes.

The object of the present invention is to remedy these drawbacks by providing a clipping system for tubes or pipes which allows easy laying of the network of tubes, in particular avoiding the measurement and alignment operations,
The present invention relates to a clip system for tubes characterized in that it is constituted by a fixing element provided with openings # res at a predetermined spacing placed on the support layer and by at least a clipping element constituted by an inner section element of hollow shape corresponding substantially to the external section of the tube - and open along one of its generatrices over a width corresponding to an angle at the center less than 1800 and by an anchoring element fixing in an opening of the fastener.

According to a preferred embodiment, the fixing element consists of a flat iron of small thickness pierced with holes at regular intervals. The anchoring element can be constituted by any known anchoring element. Preferably and to facilitate the installation of the clipping system and to avoid screwing operations or the like, the anchoring element is constituted by a self-anchoring peg.

On the other hand, the clip element is preferably made of a semi-rigid plastic material. It can be made, for example, of polyamide or the like.

Other characteristics and advantages of the present invention will appear on reading the description of an embodiment of a clipping system made with reference to the attached drawing in which
The single figure is a front elevation view
a clipping system according to the invention.

As shown in the figure, the clipping system according to the invention consists mainly of a flat iron 1 of small thickness which can be fixed by any known means such as screws or the like on the support layer 2 which can be constituted by a polyethylene insulating layer. The flat iron 1 is provided with holes 3 regularly spaced over its entire length. On the flat iron 1 is fixed the clip element 8 'proper. However, the clip elements 4 which are fixed in the holes 3 of the flat irons comprise, as described below, a self-anchoring peg, it follows that the flat iron can be fixed on the support layer 2 directly by the pegs .This clip element 4 is, in the embodiment shown, formed of a cylindrical element 5 having a hollow cylindrical internal section of radius R corresponding substantially to the external radius of the heating tube 6- made of polyethylene which must be held in place by said clip element. The cylindrical element 5 is open along one of its generatrices on an arc corresponding to an angle at the center a of 1100.

The cylindrical element is preferably made of a semi-rigid plastic material such as the extrudable superpolyamide sold under the brand NYLON. The cylindrical element 5 is provided at its end opposite to the open part with a self-anchoring peg 7 The stud 7 made in the same material as the cylindrical element ends with a conical head 8 whose base has triangular recesses so as to be able to tighten elastically when it is inserted into a hole and then to deploy and come to lock against the underside of the flat iron 1.

when used in surface air conditioning devices, such a clipping system is very simple to implement. Thus, a number of flat irons 1 are positioned on the support layer parallel to each other and with a predetermined spacing. Then, in the selected holes 3 fixed irons are fixed, the clip elements 4 proper. As the holes of the flat irons are drilled with a predetermined fixed spacing, it is thus possible to pass the heating tubes which are forced into the cylindrical elements 5 of the clip elements, parallel to each other with a spacing between them predetermined. In addition, as the clip element is capable of turning over 3600, it is possible to make the heating tubes take any desired arrangement.

the embodiment described above is capable of receiving numerous modifications without departing from the scope of the claims below.
