Description

The present invention relates to a spacer member comprising a stop portion provided with an opening and a spacer portion projecting from the stop portion.

The purpose of such a spacer member is to ensure that when attaching the thermal insulation layer to the building frame, the nails are not punched too deep, whereby a porous, e.g. rockwool insulation layer would collapse and its insulating capacity would deteriorate accordingly.

Finnish patent publication 63986 describes a strip spacer consisting of a tubular body part and a flange part at one end thereof. The body part acts as an intermediate part and its other end is chamfered to push through the insulating layer. The nail is punched through a hole in the flange section.

However, when the insulating layer to be used is a tough material or its surface is provided with a windproof layer of a tough plastic film, e.g. a polypropylene film, the problem is that the tubular body does not penetrate the windproof or insulating layer but presses the insulation into a pile. 20 This results in the loss of thermal insulation properties over a large area around the spacer.

The nailing spacer according to the present invention is characterized in that the spacer part consists of spaced-apart pin-like members. Preferably, the tips of the pin-like members 25 are sharp.

The pin-like spacer members of the nail spacer according to the invention easily penetrate even a tough plastic film and the insulating layer retains its original thickness and porosity.

.30 The invention and its details will be described in more detail below with reference to the accompanying drawing, in which Figure 1 shows a side view of a spacer according to the invention, Figure 2 shows the same spacer attached to a building and partially sectioned and Figure 3 shows a spacer seen from the side of the spacer. .

In the spacer member according to the drawing, the spacer part is formed by six pin-like members 1 which taper towards their blade tips 90452. The pin-like members 1 are connected at one end to a abutment part 3 with an opening 4 in the middle. In the embodiment according to the drawing, the abutment part 3 consists of an oval flange part 5 connected to the central part 6 provided with the opening 4 by two support ribs 7. The pin-like members are connected to the flange part.

The spacer member according to the invention is pressed into the insulating layer 8, whereby the sharp-tipped pin-like members 1 pierce the insulating layer. In addition, when the pin-like members taper towards their 10 tips, piercing occurs very easily. Preferably, the stem portions are conical. The insulating layer is attached to the building frame 9 with a nail 10, the arm part of which fits into the hole 4 in the abutment part 3 of the spacer member.

The invention is not limited to the above application, but may vary within the scope of the claims. The counter part can be of other shapes, suitably e.g. round. The number of pin-like members may be different, e.g. four. However, there are preferably at least three pin-like members. The cross-section of the pin-like members may be other than 20 round, e.g. faceted, in which case their shape is pyramidal. Their location may vary, some of them may be located, for example, in the support ribs 7. There may be more than two support ribs, e.g. four. The counter part may also be a solid plate in other respects, as long as it has an opening for a nail.
