Process for fixing an article to a substrate

Abstract

A process for fixing an article to a substrate with a mounting set including two receptacles storing an aerobic adhesive and a hydrophilic substance, respectively. The aerobic adhesive and the hydrophilic substance are removed from the two receptacles and then mixed together to prepare the fastening. A layer of the fastening composition is applied to the article. The article is fixed to the substrate by pressing the layer of the fastening composition against the substrate. The aerobic adhesive in the layer hardens because of the moisture contained in the hydrophilic substance.

3. The process according to claim 2, wherein the mechanical fastening device comprises one of a pipe clip or an adaptor.

4. The process according to claim 1, wherein the substrate comprises a wall and the article comprises a fastening element to which a piece of equipment can be attached.

5. The process according to claim 4, wherein the wall includes a wall covering of tiles, ceramic tiles, stone slabs or marble slabs to which the fastening element is attached.

6. The process according to claim 5, further comprising attaching the piece of equipment to the fastening element after the layer of the fastening composition between the wall and the fastening element has hardened.

7. The process according to claim 4, wherein the piece of equipment comprises one of a light fixture, a piece of furniture or a sanitary equipment item.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention is explained in the following with the aid of the drawings, which show in:

(2) FIG. 1: A schematic representation of a mounting set comprising the components for the fastening composition according to the invention;

(3) FIG. 2: The fastening composition mixed together inside a container;

(4) FIG. 3 The fixing of an article to a wall with the aid of the fastening composition according to FIG. 1.

DETAILED DESCRIPTION

(5) FIG. 1 schematically shows a mounting set 1 with the individual components for producing a fastening composition 2, shown in the mixed-together state in FIG. 2.

(6) The mounting set 1 comprises a tube 3 which contains an aerobic adhesive 4. The aerobic adhesive 4 in the present case is composed of modified silane (MS) polymers. The mounting set 1 furthermore comprises an amount of hydrophilic substances which in the present case are hydrophilic carrier fibers 5 that are stored inside a bag 6 or the like. In the present case, non-dried cotton is used for the hydrophilic carrier fiber 5. The mounting set 1 is completed by a spatula 7 and, if applicable, also contains operating instructions which are not shown herein.

(7) The fastening composition 2 is produced by mixing together the components just before it is used for attaching articles, namely by mixing together the aerobic adhesive 4 and the hydrophilic carrier fiber 5. The aerobic adhesive 4 and the hydrophilic carrier fibers 5 are placed for this into a container 8 or a similar container, as shown in FIG. 2, and are then mixed homogeneously with the aid of the spatula 7.

(8) The spatula 7 is preferably made of wood. The spatula 7 is first submerged in water to obtain a moisture content that is suitable for the complete hardening of the mixture. The moisture absorbed by the spatula 7 is then transferred to the hydrophilic substance, whereupon this substance is mixed with the aerobic adhesive 4, using the spatula 7.

(9) The volume share of hydrophilic carrier fibers 5 in the mixture preferably amounts to approximately 30 to 40 %, wherein the weight percentage of the hydrophilic carrier fiber 5 in the mixture is in the order of magnitude of 10 %.

(10) Immediately after mixing together the components for the fastening composition 2, this composition is used to join two articles.

(11) One exemplary embodiment is illustrated in FIG. 3. FIG. 3 shows a segment of a building wall 9, in particular of a room in a house which is provided with a wall covering 10 in the form of tiles.

(12) This wall covering 10 on the wall 9 is to be provided with a fastening element 11 on which subsequently a piece of equipment is to be mounted, in particular a sanitary equipment item such as a towel holder, a shelf, a shower set or the like, wherein several such fastening elements 11 can generally also be provided for attaching an equipment item.

(13) FIG. 3 schematically shows one component of the equipment in the form of a locking element 12 which can be fixed to the fastening element 11.

(14) The fastening element 11 has an essentially circular-disk shaped outline. The underside facing the wall 9 is provided with a recess 13 which is delimited by an edge segment 14 that extends along the complete circumference of the fastening element 11.

(15) With the fastening element 11 removed from the wall 9, for example, the freshly mixed fastening composition 2 that is shown in FIG. 2 is filled into the recess 13 on the fastening element 11 by using the spatula 7, thereby resulting in the forming of a defined, moldable layer for the fastening composition 2.

(16) The fastening composition 2 is then fitted with the layer of the fastening element 11 onto the wall covering 10 of the wall 9. Owing to the fact that the aerobic adhesive 4 in the fastening composition 2 immediately has a certain adhesive force, the fastening element 11, which has only a diameter of a few centimeters and has a low inherent weight, is held securely against the wall covering 10.

(17) Bore holes extending in axial direction and ending in the recess 13 can be provided in the fastening element 11, so as to prevent the fastening composition 2 from escaping on the side from the fastening element 11 while it is fitted against the wall covering 10. Excess fastening composition 2 material can then flow into these bore holes while the element is attached to the wall covering 10.

(18) Even though the fastening composition 2 is contained in a completely enclosed space, following the attachment of the fastening element 11 to the wall covering 10, and does not come in contact with the ambient air, the aerobic adhesive 4 in the fastening composition 2 can harden completely from the inside because of the admixture of the hydrophilic carrier fiber 5 because this hydrophilic carrier fiber 5 has stored the moisture, respectively the oxygen, required for the hardening.

(19) A load-bearing attachment of the fastening element 11 to the wall 9 is obtained as soon as the fastening composition 2 has hardened, so that the equipment item can be attached to the element. In the present case, the locking element 12 is attached with the aid of a screw connection or a plug-in connection to the fastening element 11. The locking element 12 comprises a holding element 16 to which the equipment article can be attached, e.g. a towel holder.
