Description

The invention relates to an insulating body for flat roofs, comprising a funnel-shaped recess for fixing a drain body.

In the prior art exists a variety of Dämmkörpern (basic bodies), in particular industrially produced insulating body with the negative mold for corresponding drain body.

The insulating body usually have a radially extending application groove, which are arranged within the insulating body, which can be filled with an adhesive to attach a drain body to the insulating body.

A disadvantage of the prior art is that a rotation of the drain body relative to the insulating body is not excluded.

The object of the invention is to reduce a rotation of the drain body relative to the insulating body.

The object is achieved by an insulating body according to claim 1.

Advantageous developments are defined in the subclaims.

• – wobei die Ausnehmung eine Einlassöffnung und eine Auslassöffnung aufweist, und
• – wobei die Ausnehmung eine Wandung aufweist, die die Einlassöffnung mit der Auslassöffnung verbindet,

dadurch gekennzeichnet, dass in der Wandung neben einer radial verlaufenden Rille Zusatzrillen vorgesehen sind.According to one aspect of the invention, a damping body for flat roofs is proposed, comprising a funnel-shaped recess,

• - wherein the recess has an inlet opening and an outlet opening, and
• - wherein the recess has a wall which connects the inlet opening with the outlet opening,

characterized in that additional grooves are provided in the wall in addition to a radially extending groove.

The radially extending groove and the additional grooves run in the wall of the insulating body.

By providing the additional grooves additional areas are provided for bonding. By means of the additional bonding, the torsion protection of the insulating body can be improved with a drain body.

Preferably, the insulating body is formed cuboidal.

The inlet opening, the outlet opening and the recess preferably have an approximately circular shape.

Preferably, the radially extending groove is formed as a continuous annular recess. Particularly preferably, at least one radially extending groove is provided.

According to a development of the invention, the groove and the additional grooves are adapted to be filled by means of an adhesive in order to fix a drain body on a surface of the insulating body.

Preferably, the adhesive is a mounting foam. Preferably, the adhesive is polyurethane.

Preferably, the drain body on a cylindrical part. Preferably, the insulating body is adapted to receive the drain body via its funnel-shaped recess.

Preferably, the drain body is configured such that after a successful joining of the insulating body with the drain body, both parts fit into each other.

In this way, by means of the adhesive, which has been applied to the groove and the additional grooves, the drain body in the assembled state can be fixed to the insulating body.

According to a development of the invention, the recess has a variable diameter.

This allows a variety of design options of the recess.

Preferably, the recess has a diameter which tapers from the inlet opening to the outlet opening.

According to a development of the invention, the wall has a step-shaped region in which the radially extending groove is arranged and through which the additional grooves run.

The provision of a step allows the drain body can rest in the region of the wall.

According to a development of the invention, the additional grooves extend in the axial longitudinal direction, in the radial circumferential direction or obliquely in the wall.

Thus, simple embodiments of the additional grooves can be realized.

According to a development of the invention, the additional grooves are wavy in the wall.

Thus, an enlarged feed surface for the adhesive can be realized.

According to a development of the invention, the additional grooves have a depth of about 2 mm.

In this way, the additional grooves are sufficiently deep to receive a sufficient amount of adhesive.

According to a development of the invention, the groove and the additional grooves cross each other.

In this way, adhesives can be joined together to adhesive webs, which causes improved adhesion with the drain body and the insulating body in an assembly of the two components.

Preferably, the drain body is formed at its standing with the insulating body in the assembled state in contact areas as a counterpart, in particular as a negative mold to the insulating body.

The invention will now be further illustrated by way of example with reference to the drawings. Hereby shows:

1 a schematic view of a Dämmkörpers invention for flat roofs,

2 a schematic view of the insulating body according to the invention 1 with a partially introduced into the insulating body and body

3 a schematic view of a damping body according to the invention in the installed state.

1 shows a schematic view of a Dämmkörpers invention for flat roofs.

The insulating body 1 is z. B. made of a polyurethane foam and has a cuboid structure with a funnel-shaped recess 2 on. The recess 2 has an inlet opening 3 and an outlet opening 4 on. Furthermore, the recess has 2 a wall 5 on that the inlet opening 3 with the outlet opening 4 combines.

In the wall 5 are next to a radial groove 6 additional grooves 7 intended.

The groove 6 and the additional grooves 7 are adapted to be filled by means of an adhesive to a drain body (in accordance with 2 ) to fix. Preferably, the adhesive used is polyurethane.

The recess 2 has a variable diameter. The wall 5 is stepped.

In the area of the stepped formation are the radially extending groove 6 and the additional grooves 7 in the wall 5 brought in.

The additional grooves 7 extend in the axial longitudinal direction in the wall 5 ie from the inlet opening 3 in the direction of the outlet opening 4 , where the grooves 6 and the additional grooves 7 cross.

The additional grooves 7 have a depth of about 2 mm. Furthermore, the additional grooves have a width of about 10 mm and a length of about 30 mm.

2 shows a schematic view of the insulating body according to the invention 1 with a partially introduced into the Dämmkörper drain body.

The drain body 8th has a cylindrical part 9 on. The insulating body 1 is set up over the recess 2 the drain body 8th take.

The drain body 8th is configured such that after a successful joining of the insulating body 1 with the drain body 8th , fit both parts together.

By means of the adhesive 15 (please refer 3 ), who on the groove 6 and the additional grooves 7 can be introduced, the drain body 8th in the assembled state on the insulating body 1 be fixed. This can cause a rotation of the drain body 8th opposite the insulating body 1 is further reduced.

3 shows a schematic view of a Dämmkörpers invention in the installed state. The adhesive 15 is already in the above groove 6 and the additional grooves 7 been applied.

The insulating body 1 is in the recess of a thermal insulation 10 integrated. The thermal insulation 10 lies on a vapor barrier 11 on, in turn, on a substructure 12 rests.

The seal 13 is on the flange of the drain body 8th applied.

There is also a gully 14 provided the substructure 12 penetrates and a portion of the cylindrical part 9 of the drain body 8th receives.

On the drain body 8th is a gravel trap 16 intended.
