SUSPENSION METHOD AND INSTRUMENTS

The present invention relates to a suspension method and means for use in construction, wherein a protrusion / protrusions, a kind of loop (s) on which the fastening means (s) are mounted are made on the steel plate acting as a suspension carrier, or on another metal plate or plate made of another material.

Steel plates and other metal plates or plates made of other materials are used e.g. in the manufacture of form plates used in construction as load-bearing structures, roof coverings, claddings 10, etc. in a wide variety of applications. One such use of steel plates is e.g. composite structures such as composite slabs, where the steel sheet plate tm, the metal plate acts simultaneously as a concrete casting solvent and reinforcement.

15 The problem has become how to hang a suspended ceiling, pipes, etc. from the installed structure. the latter made. For example, hanging on form plates made of steel sheet is reasonably possible, because the fastening means can be anchored to the plate, e.g. by drilling. In contrast, in composite slabs and similar composite structures, it is difficult to anchor the fastening means because there is a hardened concrete or similar casting component on the slab. In all constructions, it is advantageous if the fastening of suspended ceilings, pipes, etc. can take place without a separate method based on the drilling, welding, etc. work step. In its simplest form, the work can take place in such a way that the pre-formed fastening means is threaded onto the plate at the suspension point made for it.

Most preferably, such a hanging point is created in such a way that it is formed during the manufacture of the sheet from the material itself and the hanging point is always available whether it was needed or not, i.e. it belongs to the product itself.

It is further preferred that the fastening means is simple and preferably such that it can be made on site during installation, whereby the length and quality of the hanging means and what is to be hung are known.

In the suspension method of the invention, the above-described problems have been solved and said advantages have been achieved by making a protrusion / protrusions cut into the steel plate or other metal plate or a plate made of another material by stamping, manipulating or otherwise cutting the plate material-2 itself. attaches to the plate at both edges and on which the fastening means is mounted.

The fastening member is made, for example, in such a way that it is formed, for example, from a conventional ¢ 4 mm galvanized wire, the so-called skramlalan, which is available from all hardware stores and is commonly used in construction. A suitably shaped loop is made at one end of such a wire, which is threaded into the projection (s) on the plate, so that the fastening means can thus also be manufactured on site if necessary.

15 There are no restrictions on the wire thickness of the fastener, its length, or the shape of the loop, as long as it functions in the intended function. However, it is preferred that the design of the loop of the fastening means is such that it adheres as rigidly as possible to the protrusion (s) of the plate.

20

The fastening means according to the invention are characterized in that the fastening means has a bent loop (s) for fastening to the projection (s) of the plate.

Such a design of the end of the fastening means which can be fastened as rigidly as possible can be such that an angle of 90 ° is made with the end intended for fastening the straight wire so that the length of the end bent from the wire is about 60..100 mm, preferably 80 mm. The end of this length is bent into a loop, whereby the wire forms a circle, an ellipse or similar arc-30, from which an arc of about 20..60 mm leaves the wire exhausted, if one thinks of an expired arc. In this case, the end of the loop is first threaded into one protrusion of the plate and in the vertical position (the fastening means is in its final position) the fastening member is rotated so that the end of the loop threads through the second (adjacent) protrusion. The rotation is continued until the fastening means is firmly anchored in the two projections and can be supported on the plate at the same time. The distance between the successive projections can be arbitrary, but preferably 30..50 mm, in which case the fastening means can be rotated as described above, even in tight spaces.

There are no restrictions on the width of the protrusion per se, as long as it can withstand the stresses to which it is subjected without breaking. A suitable width is between 4..20 mm, preferably 6..12 mm.

5 There are also no restrictions on the protrusion of the protrusion from the plate. However, in the case of a metal sheet, the maximum protrusion of the protrusion is determined on the basis of the creep properties of the plate, the protrusion being 3..12 mm, preferably 5..9 mm.

10 There are also no restrictions on the cross-sectional shape of the protrusion. In the case of a metal sheet, the most preferred shape is one that least creeps the sheet, i.e., the cross-sectional shape is somewhere between a triangle and a semicircle when the sheet is thought to form one side.

The location of the protrusions made on the plate is not limited in any way, but the location is usually determined by the requirements of the object to be hung. In some applications, the best location of the protrusion can be individually identified in advance. Such a place is, for example, in the case of the shaped plates used in the other plates 20 in the seam of the two plates and still in the plate which remains the lowest when the two plates are fastened together. When the protrusion is taken from the material itself, a hole is created in the plate.

When two slabs are joined together, the intact slab that comes on top will cover the hole (s) so that the concrete cannot block the protrusion. The 25 hole (s) caused by the protrusion can also be blocked with tape or other protection.

The direction of the protrusion can be arbitrary, in which case the direction of the protrusion means the direction created by looking at the protrusion along the line 4 79375 to which the attachment points of the protrusion converge. For example, in the production of steel sheet profiles in a continuous line, the direction of the projections is suitably the same as the line direction, the projections can be made by mangling with rollers, one with protrusions defining the shape of the projection and the other with corresponding depressions and intersecting sides. Manufacturing is also possible with rollers in which one has protrusions and the other a mere cutting groove.

The invention will now be described in detail with reference to some embodiments of the invention shown in the figures of the accompanying drawings, to which the invention is not intended to be narrowly limited.

The fastening means of Figures 7c and 7d also has a hook 5 at one end, which is used, for example, as an aid for hanging a pipe or the like. The location of said hook may just as well be 10 threads, a closed loop or the other to which the piece or structure or the like to be hung can be easily attached.
