Description

ATTACHMENT ARRANGEMENT

ENGINEERING

[001] The present invention concerns a fastening arrangement. In particular, the invention concerns a fastening arrangement for fastening the plaster mesh to a wooden element.

BACKGROUND

[002] A commonly used facade structure comprises a load-bearing or non-load-bearing reinforced concrete inner shell cast against the inner surface formwork and thermal insulation. On top of the thermal insulation there can be base and filling plaster made at the factory. On top of these, joint and surface plastering can still be done at the construction site. For plastering layers on top of the thermal insulation — the plastering net is fixed with plastering brackets, i.e. with U-holes, which anchor the plastering net to the reinforced concrete. Plaster fasteners are placed before the concrete has fully hardened, so they bond to the concrete as it hardens to its final hardness.

[003] In order to reduce the carbon footprint of the facade structure, it has become relevant to replace the reinforced concrete inner shell with a wooden element. In this case, the traditionally used plastering fasteners are not suitable for attaching the plastering mesh to the wooden element. Consequently, there has been a need to develop the fastening of the plastering net.

S [0016] FIG. 1 shows the fastening arrangement 100. The fastening arrangement 100 — comprises a wooden element 110, a plaster mesh 120 and an insulator 130 between the wooden element 110 and the plaster mesh 120. The plaster mesh 120 has a first surface 121 facing the wooden element 110 and an opposite second surface 122. The fastening part 150 is placed on the plaster mesh 120 to the second surface 122. The fastening means 160 extends from the fastening part 150 through the insulation 130 to the wooden element 110.

[0017] The fastening part 150 can be an elongated, round or oval plate-like body. Thus, it is possible to make the fastening part thin enough that it does not stand out under the plastering.

FIG. 2 shows the fastening part 150. In this example, the fastening part 150 is an elongated plate-like body. The length of the fastening part 150 is greater than its width. The fastening part 150 is placed on the surface of the plastering net 120.

[0019] The fastening part 150 may comprise a recess 153 which extends towards the insulator 130 when the fastening arrangement 100 is assembled. Thus, it is possible to place the base of a fastening device, such as a screw or a nail, in the recess. In this case, the base remains at the level of the surface of the fastening part or slightly below the surface of the fastening part. Therefore, the base does not stand out from under the plastering. At the same time, the ends of the fixing part do not press the plaster mesh into the insulation, but set it at the correct height. Thus, the height of the plaster mesh can also be set as desired by dimensioning the fixing part.

[0020] The recess 153 can be formed in the middle of the fixing part 150. When the fixing part 150 is an elongated plate-like body, the recess 153 can be equidistant from both ends of the fixing part 150 in its longitudinal direction. When the fixing part 150 is a round plate-like body, the recess 153 can be formed in the middle of the body. & [0021] The depth of the recess 153 can be 3-8 mm, preferably 3-4 mm. Hence

It is possible to place the base of a fastening device, such as a screw or a nail, in the recess

S deep enough. >

I 25 [0022] The recess 153 can comprise a fastening hole 154 for a fastening means 160

[0024] The fixing part 150 can be an elongated plate-like body, which comprises a first side part 151 and a second side part 152, which are connected to the recess 5 153. Thus, the first side part and the second side part anchor the fixing part on the surface of the plastering net. In this case, the recess is placed at the right distance from the plaster mesh.

In addition, the side sections distribute the forces caused by the fastening on the surface of the plaster mesh. Thus, the attachment becomes reliable.

[0025] The first side part 151 and the second side part 152 can extend — in opposite directions from the recess 153 in the longitudinal direction of the fastening part 150. Thus, the side sections distribute the forces caused by the fastening on the surface of the plaster mesh in different directions.

This also ensures reliable anchoring of the fastening part on the surface of the plastering mesh.

FIG. 2 also shows the first side part 151 and the second side part 152, which extend in opposite directions from the recess 153 of the fastening part 150 — in the longitudinal direction. In this example, the side portions 151, 152 are rectangular, but may also be of any other suitable shape. Furthermore, in this example, the side portions 151, 152 are longer than the mesh diameter of the plastering net 120. Thus, the fastening part sits firmly on the surface of the plaster mesh, while the threads of the plaster mesh support the side sections. — [0027] The first side part 151 and/or the second side part 152 can comprise at least one opening 155. The opening 155 can be formed in the middle of the side part 151, 152, at the edge or at another suitable point. Thanks to the opening, less material is needed to manufacture the fastening part. In addition, with the help of the opening or openings, it can be ensured that too large uniform surfaces are not formed on the surface of the 5 plaster mesh, in which case the fixing part = 25 — might be heard through the plastering. In addition, the opening or openings improve the adhesion of the plaster at the fixing part. a

Thus, at least one side portion 151, 152 can be fork-like. An open section is thus formed between the first section 151a, 152a and the second section 151b, 152b. The side part 151, 152 can be open from the longitudinal end of the fastening part 150. Thanks to such a design, less material is needed to manufacture the fastening part. In addition, with the help of the open section, it can be ensured that too large uniform surfaces are not formed on the surface of the plastering mesh, in which case the fixing part could be heard through the plastering. In addition, the open part improves the adhesion of the plaster at the fixing part. — [0030] FIG. 4 shows the fastening part 150, whose first side part 151 and second side part 152 comprise the first part 151a, 152a and the second part 151b, 1520, which are separated from each other in the longitudinal direction of the fastening part 150.
