Abstract

The present invention relates to a method to connect two profiles of steel, preferably vertical steel joists and horizontal beams, wherein a especially formed fitting is brought towards the end or bottom of a first steel profile, passing edge reinforcements (a') at the profile and to a position where it touch bottom at the first steel profile and to be fixed there. The method is characterized in that the other end of the fitting is first fixed at an other steel profile after that a proper length adjustment has been carried out by telescopic functioning between fitting and profile, alternatively that the other end of the fitting first is fixed at the other steel profile prior to be brought to the end or to the bottom of the first steel profile (Ia) to be fixed at that position after carrying out a possible length adjustment by the telescopic functioning between the fitting and the profile.

Description

A method to connect steel profiles, and fittings and steel profiles to perform said method

The present invention relates to a method to connect steel profiles, i.e. steel joist with a shortened length by using of an especially formed fitting with a telescopic functioning and fittings and steel profiles to carry out said method.

The definition of steel profiles in this context, i.e. in so called light weight constructions is cold-rolled profiles with a 0,7 to 2,0 mm in thickness.

Steel profiles have found an increased use in the building sector, among other things at the preparation of not carrying and carrying wall constructions.

Here vertical steel profiles called steel joists are connected between horizontal profiles at the ceiling and at the floor; these profiles are called steel beams. Up till now it has been important that the joists are fit in length to the height of the room for said specific application.

At certain applications it should be easier to get a joist- beam construction ready in a not finished mounted position, e.g. in association with a work bench, or with the construction laying on the floor. This may not be accomplished with known methods and lengthening-pieces.

The purpose of the present invention is to obtain a method and a fitting for connecting of steel profiles towards floors and/or ceilings; in where to problems mentioned above with exact cutting into the right lengths of the joists are eliminated.

An other purpose is to make a fixing between the beam and the joist possible by using pre drilled or pre punched holes or material weakening in the shape of a hole series.

The purposes of the invention mentioned above are obtained by a method and a fitting having the characterizing clauses mentioned in the claims.

By using a connection according to the present invention of vertical/horizontal profiles for an outer wall a certain telescopic action can be allowed. This admits for the vertical profiles not to be pre cut in exact lengths any more but may have a UNDER length of about 20 mm. This makes it possible to pre built walls, e.g. with the height of 2480 mm, where the height of the vault is 2500 mm. After that the wall has been put in place and been folded into a correct position the upper horizontal profile is pushed up against the ceiling, which accordingly is possible with the fitting according to the invention having a telescopic functioning. After that the horizontal profile is lift against the ceiling the fitting is fixed in the vertical joist with the aid of a proper amount of fastening means.

The fitting according to the invention is equipped with a hole pattern corresponding to elliptical holes at the end of the joist or the outer wall profile and allows a mounting of the profile into the fitting just using threading screws, i.e. not needing self drilling screws. This will make the building process more effective and will thus considerably reduce the building time.

The invention will now be described in connection to embodiments shown on the accompanying drawings, where

Fig. 1 is a perspective view of a first basic accomplishment of a fitting according to the present invention,

Fig. 2 is a perspective view from beneath of a second, modified accomplishment of a fitting according to the invention,

Fig. 3 is a perspective view at an angle from above of the fitting according to fig. 2, and where

Fig. 4 is a perspective view of two vertical joists and a horizontal beam, and between which the fitting according to the invention is used with the possibility of a telescopic functioning.

Fig. 1 shows a perspective view of a fitting and/or of a terminal reinforcement 8 according to the present invention. The fitting 8 encloses a rectangular framework 8a, one edge 9 of which is transferred into a perpendicularly bent connection flange 10 and the other opposite end edges 11 and 12 of which have grooves 13a and 13b and are transformed in relation to the frame work 8a into perpendicularly and grooved flanges 14 and 15. In the frame work 8a of the fitting 8 there is also an opening 16, which appear to advantagously can be used to collect linings, pipes and cables being drawn within the wall.

Fig. 2 and 3 show an alternative accomplishment of a fitting being formed from the one and same piece of material. By having bevelled edges on the "introducing" end of the fitting it is very easy, also for an untrained user to understand the use and handling of the fitting in connection to attachment at a profile joist work. 13c is a material bridge occurring when the grooves 13a and 13b are formed when punching a work piece.

In fig. 4 the fitting 8 is shown in place inwardly at attachment between vertical steel joists 2a and a horizontal steel beam Ia. Here can be seen how the grooves 13 in the fitting 8 are taken up den inwardly bent free flange ends of the U-shaped beam Ia. In this case it is evident that neither any cutting nor removing of material from the joist or from the beam has to be done prior to connection with the aid of the fitting 8. To fix the fitting at the joist and at the beam after that a necessary telescopic action has taken place to adjust a height measure attachment means are used intervening in not board receiving surfaces of the joist or beam. Said attachment means, preferably thread pressing screws are screwed in a suitable hole or allotted hole in a hole row at the rib portion of the joist.

The invention is not restricted to the above mentioned embodiments but modifications can be done within the scope of the patent claims mentioned below.

Claims

1. Method to connect two profiles of steel, preferably vertical steel joists and horizontal beams, wherein a especially formed fitting is brought towards the end or bottom of a first steel profile, passing edge reinforcements (a') at the profile and to a position where it touch bottom at the first steel profile and to be fixed there, characterized in that the other end of the fitting is first fixed at an other steel profile after that a proper length adjustment has been carried out by telescopic functioning between fitting and profile, alternatively that the other end of the fitting first is fixed at the other steel profile prior to be brought to the end or to the bottom of the first steel profile (Ia) to be fixed at that position after carrying out a possible length adjustment by the telescopic functioning between the fitting and the profile.
2. Fitting to connect steel profiles with the same or similar cross- sections and to carry out the method according to claim 1, characterized in a framework (8a) the one edge (9) of which is transferred into perpendicularly bent connection flange (10) and the other opposite end edges (11, 12) of which have grooves (13a, 13b) and are transformed, in relation to the frame work, into perpendicularly directed and grooved flanges (14, 15), which flanges are so long that they admit a telescopic functioning.
3. Fitting according to claim 2, characterized in that the height of the connecting flange and of the grooved flanges perpendicularly directed towards the framework of the fitting corresponds to the height of the flanges at the C-shaped profiles.
4. Steel profile to be fixed and locked at another steel profile by using a method according to claim 1 and a fitting according to claim 2, characterized in one or several rows of hole allots on its rib side.
