The invention relates to an anchoring means for providing a fireproof and/or wear resistant lining on an object made of metal, wherein the build-up of a polygonal folded base portion is intended to be fixed to the object by means of a to the object welded pin, which is provided with an anchoring thread for receiving a part attached to a polygonal mid section of the anchoring means, comprising an internal thread, wherein lips which extend transversely to said polygonal base portion, join the edges of said base portion, which lips are bended over an angle with respect to said mid section and having mutually enclosing bending lines.
Such an anchoring means is known from the Dutch patent 193.073. In this known embodiment a relatively large mid section and perpendicular to this mid section folded short arms or lips are applied.
As such this known anchoring means suffices, but with some lining materials and/or under difficult working conditions when applying the lining material on objects it may happen that the space between the anchoring means and the object is not thoroughly filled with lining material and underneath the anchoring means a non filled space or “air chamber” remains, which is unwanted.
According to the invention arms interconnected with the mid section of the anchoring means are bend with respect to the mid section over an angle of less than 90°, whereas the free ends of the arms interconnected with the mid section are bended with respect to the arms such that the free ends extend parallel to the plains, that are positioned in essence perpendicular to a plain extending parallel to the mid section. Under the term “bended over an angle” it is clearly meant that the angle is significantly larger then 0°, i.e. at an angle of about 0° one cannot speak of “bending”. As a consequence the term “bended over an angle of less than 90°” will inevitably refer to an angle between “significantly larger than 0° and smaller than 90°”, such as between 5° and 90°.
In practise it has been experienced that for this embodiment of the anchoring means according to the invention applying the lining material effectively between the given object and the anchoring means can be established without danger of remaining “air chambers” between the anchoring means and the object to which the anchoring means is applied, such that the lining applied is effected very effectively.
The invention will be explained in detail with respect to the accompanying figures.
The starting piece shown in
For the manufacturing of the anchoring means as shown in
A further important difference in comparison to the anchoring means disclosed in NL 193.073 is that the present free ends extend parallel to planes, which are substantially perpendicular to a plane extending parallel to the mid section. Also this difference provides the advantages mentioned above.
The free ends 4 of legs 2 are bended with respect to legs 2 along folding lines 8 schematically shown in
In an example the plate section had a thickness of between 1.2 mm and 3.0 mm, preferably a thickness of between 1.5 mm and 2.0 mm. A too large thickness has as a consequence that the present anchoring means is difficult or not manageable for a person that is applying the anchoring means. A too small thickness has as a consequence that the anchoring means is for example mechanically too weak.
As is shown further in
For the attachment of the anchoring means to an object formed out of metal, which is to be applied with a fire proof and/of a wear resistant lining material, use is made of pens or styles as is shown in
Such a pin 10 is build from a massive shaft 11, which shaft forms a single part with an external screw thread 12 being provided thereon. Thereby the external diameter of the part 12 is smaller then the external diameter of the part 11, such that at the transition between parts 11 and 12 a collar 13 is formed.
For attaching of the required number of anchoring means to an object provided the lining pins 10 are being welded to the object with an end thereof turned away from the screw tread end 12, for instance by pressing the pins with a suitable tool against the wall and heating the ends of the pins that are to be welded.
Subsequently the anchoring means are applied to the pins which are welded to the object by screwing an anchor means on each pin using the nut 9 welded to each respectively anchoring means. By screwing the anchoring means to the pin the nut 9 will at a given moment come in contact with collar 13 whereby it is prevented that the anchoring means is screwed too far to pin 11 and further that the anchoring means is at a required distance in each instance with respect to the object to be lined and unwanted deformation of the anchoring means will be prevented.
In practice it is observed that in particular by the acute development of the relatively long arm 2 being connected to the mid section 1, that can resiliently diverse, the space in between the anchoring means and the object to be lined can effectively be filled with the lining material in an easy way as can be accomplished and the presence of optional air chambers can be prevented in the space between the anchoring means and the object to be lined.
