    whereby the contact between them has the potential to become tight.
    The joining of two profiles takes place either by welding or screwing. When welding, the workpieces are stabilized in a first phase, e.g. by spot welding in a suitable position. The working method that is currently applied in this phase usually means that the workpieces, profiles / joists are held in place with the help of clamps and clamping tools of various kinds, and often together with support blocks or angle irons that are suitable for the purpose. There is also a type of holding tool, so-called magnetic holders and magnetic fixtures, which e.g. holds together two profiles at a certain angle in relation to each other during the first phase of the welding work. After the workpieces have been fixed by spot welding, the support tools can be removed and the joint welded in its entirety. In cases where the profiles are joined together with screws, the workpieces are stabilized in basically the same way as when welding.
    The magnetic holders that are currently on the market and that can be used in this phase of the work are lacking, in e.g. in the case of the workpieces having a square profile, lateral control which may complicate the fitting of the workpieces. Their direct abutment surface against the workpieces consists of the side edges of the two relatively thin metal sheets surrounding the magnet. The slot that is formed between the metal plates can increase the contact surface to some extent when the workpieces have e.g. round profile. No part of the abutment surface, neither the edges of the surrounding metal sheets nor the bottom of the slot, has been made of materials which increase the friction in the longitudinal direction of the holders. The frictional force is therefore limited, which means that the tools cannot be loaded with particularly large weights or forces. These tools are made with predetermined angles between the structural elements, often 90 ° and 45 ° or 90 °, 60 ° and 30 °. The tools are also not designed so that clamps or other holding tools can be easily applied to strengthen their load-bearing capacity if necessary.
    The problem of being able to fix the workpieces during the first phase of the work is the same regardless of whether the additional construction element is to be applied vertically or horizontally or in other directions.
    Various attempts have been made in the past to design a tool that can facilitate the holding of workpieces prior to welding.
    A PCT application previously submitted by BreTools AB, PCT / SE2009 / - 050334, discloses a tool intended for joining structural elements to be joined at an angle to each other. However, the tool is only intended for a single fixed, and right, angle.
    JP2001040878 discloses a fixing plate provided with a magnet which allows the fixing plate to be temporarily applied to a steel profile against which another profile can be fixed and attached with the support of the fixing plate. The described fixing plate differs constructively from the present invention and has a very specific and limited field of application due to its construction. The magnet is controlled by a switch, which indicates that it also requires electrical energy to function, which is a considerable disadvantage.
    SUMMARY OF THE INVENTION An object of the present invention is to demonstrate a device which facilitates and simplifies the work of generally joining steel joists and profiles.
    A further object of the invention is that the tool should be easy to use, ie to assemble and disassemble.
    A further object of the invention is that the tool should at least in its basic design be cheap to manufacture and use.
    These and further objects and advantages are achieved according to the invention by a device according to the features stated in the characterizing part of claim 1.
    The present invention thus relates to a fixing tool for fastening structural elements, such as e.g. bars and profiles of steel, to each other and a method for joining the structural elements using the fixing tool.
    The invention consists of a fixing tool which is intended to be quickly and easily applied temporarily to a rule or profile of metal to provide support for a further rule or profile which is intended to be mounted at an angle to the first. The joining / profiles are joined by welding, screwing or another similar method.
    The present invention is a simple and completely mechanical construction without electromagnets, switches etc. and which is thus easy for the user to carry and use in the desired place. The tool according to the invention is very easy to handle and gives an excellent working result.
    One aspect of the invention is to provide a device which facilitates and simplifies the work of fixing the construction elements next to each other in a first phase, after which in a second phase the joining can be completed.
    The invention is characterized in that it comprises two rectangular plates, each side folded at right angles and joined together in one short side of each plate by a hinge and with permanent magnets inserted in each plate and folded side so that first one half of the tool can be mounted against a structural member and fixing it in the intended position by the magnetic pulling force and the frictional force formed by the pulling force of the magnets and the friction between the plate, with its folded side, and the structural member, after which a second structural member can be fixed in the intended position against the first by the second the plate and its folded side and the corresponding forces formed between the plate, with its folded side, and the structural element. The short side of the folded sides, respectively, is cut obliquely so that the legs of the tool can be folded towards each other to a suitable extent, e.g. so that the legs in one end position form a 90 ° angle with each other.
    The rectangular plates and their respective folded sides are made of a non-magnetic material, e.g. stainless steel or hard plastic so that the magnetic fields formed by the magnets do not propagate in the plates and adversely affect the welding work.
    The fixing tool can in an alternative embodiment be provided with an angle measuring means which also comprises a device which locks the tool at the desired angle. For example, a circular disc centered in the hinge axis of the hinge is attached, welded or glued to the underside of one leg of one of the fixing tools.
    The disc is graded so that the angle between the legs of the tool can be read towards the inclined short side of the movable leg, which points towards the center of the hinge shaft. After setting the desired angle, the disc is fixed to the movable leg with a metal screw or equivalent.
    According to another aspect of the invention, there is provided a method of securing structural members such as steel bars / profiles.
    After the two structural elements have been cut at the desired angle, the fixing tool is placed against a first structural element connecting to the intended position of a second structural element. One leg of the fixing tool is attached to said first structural member by means of the magnets inserted in the plate of the fixing tool and its folded side and held in position by the traction of the magnets and the frictional force between the plate of the fixing tool and the structural member. The second leg of the fixing tool is attached to the second structural element in a corresponding manner and in the intended position opposite the first structural element, after which the structural elements can be joined in a first phase by spot welding or with screws or the like, after which the fixing tool can be removed with simple handles and joining completed.
    In the case where the tool with the alternative embodiment is used, the angle between the legs of the tool has been fixed in a first working step, after which the above-described method for fastening the construction element can be applied.
    The fixing tool consists of two rectangular plates, each folded at right angles and joined together in one short side of each plate by a hinge and with magnets inserted in each plate and folded side so that first one half of the tool can be attached to a structural element and fix this in the intended position by the magnetic pulling force and the frictional force formed by the pulling force of the magnets and the friction between the plate with its folded side and the construction element, after which a second construction element can be fixed in the intended position against the first by the second plate and its folded side and the corresponding forces formed between the plate with its folded side and the structural element.
    The plate with its folded side is preferably made of a non-magnetic material such as stainless steel or some type of hard plastic. The magnets of the permanent type inserted in the respective plate and folded side are mounted with screws in the plate for interchangeability.
    The invention facilitates the work with the joining of building rules and steel profiles by the fact that the work can be carried out faster and safer in relation to what is possible with hitherto known aids and tools.
    Further features and advantages of the invention will become apparent from the following, more detailed description of the invention, and from the accompanying drawings and other claims.
    BRIEF DESCRIPTION OF THE DRAWINGS The invention is described in more detail below, in some preferred embodiments, with reference to the accompanying drawings.
    Figure 1 shows a fixing tool according to the invention in a basic embodiment fixed to two construction elements which are to be joined at an angle to each other.
    Figure 2 shows in perspective view the design of the angle fixing tool in more detail seen from the side where the construction elements are fitted.
    Figure 3 shows the fixing tool according to figure 2 seen from its opposite side.
    Figure 4 shows a side view of the angle fixing tool, showing partly how the locking device is designed, and partly how the magnets are fitted and fastened in the punched tabs on the plates of the tool.
    Description of preferred embodiments Figure 1 thus shows a fixing tool 1 according to the invention in a basic embodiment fixed to two construction elements 2,3 which are to be joined. The two construction elements 2,3 each connect to a base plate 4,5 with inserted magnet 6,10 and to a side plate 8,9 with inserted magnet 7,11 where the side plate 8,9 is folded in preferably at a right angle relative to the base plate. 4.5. Each base plate 4,5 and side plate 8,9 form a leg 1a, 1b of the fixing tool 1. The side plates 8,9 have an obliquely cut edge 19,20 in the edges facing each other so that the fixing tool 1 can be angled, for example between 0 ° and 270. ° but the fixing tool 1 can of course also be designed for other angular ranges. A joint l2, here a hinge, unites the base plates 4,5 articulated with each other. The fitting and fastening of the magnets 6,7, 10, 11 in the base and side plates 4,5,8,9 is described in more detail below.
    Figure 2 shows in more detail the design of the fixing tool 1, which here is also provided with an angle measuring means 21 for setting, and locking, a certain desired angle between the legs 1a, b of the fixing tool 1. In the base plates 4,5 and the side plate 8,9, tabs 13,14,15,16 have been punched out and folded out slightly so that permanent magnets can be fitted and fastened in the fixing tool 1 with screws and nuts. This is also shown in figure 4. Figure 2 further shows a design of the fixing tool 1 where the side plates 8,9 at their respective outermost ends are slightly extended in relation to the base plates 4,5, after which the elongated parts 17,18 are folded down substantially perpendicular to longitudinal direction of the side plates 8.9.
    Furthermore, the shaft 12a of the hinge 12 has been extended so that the fixing tool 1 can rest against a base relatively stable on the extended shaft 12a of the hinge and the folded-down parts 17,18.
    This facilitates the fitting of the two structural elements 2,3 to be joined in the fixing tool 1.
    Figure 2 also shows how the side plates 8,9 are cut obliquely in their respective short ends 19,20 facing each other so that the area for the angular adjustment of the fixing tool 1 has a purposeful space. In one side plate 9 a flap 22 has further been punched out so that an angle measuring means 21, here a circularly graded disc, fixed to the side plate 8 and centered in the axis 12a of the hinge 12, can run freely between the punched flap 22 and the side plate 9. the round disc can be graded so that the angle between the legs 1a, b of the fixing tool 1 can be read towards the oblique edge 20 of the plate 9.
    Figure 3 shows the fixing tool 1 seen from the opposite side, in relation to Figure 2. The legs 1a, b of the fixing tool 1 can be fixed at the angle set by means of a locking member 24, here a screw which is screwed through the punched tab 22 and which locks the circularly graded disc against the side plate 9. The threaded hole, placed in the punched tab 22, can be provided in various ways e.g. by means of a nut 23 which is fastened to the tab 22 over a hole drilled through it.
    Figure 4 shows partly in section i.a. the design of the locking member 24. The figure also shows, partly in section, the design and attachment of a magnetic element, a permanent magnet 11, in the punched tab 16 of the side plate 9. The punched tab 16 has been bent / folded or shaped so that the magnet 11 can be mounted immersed with a screw 25 and nut 26 on the side of the side plate 9 against which the construction elements 2,3 abut. The magnet II can be easily replaced by said construction when it no longer functions satisfactorily. It is important that the magnet II can be applied in contact with the construction elements 2,3 in order to obtain the best possible holding.
    For that reason, the active surface of the magnet 11 is arranged at a level with the surface of the side plate 9 or so that it protrudes beyond the surface of the side plate 9 a few tenths of a millimeter. The magnet 11 may also be coated with a layer / casing 27 of a rubber compound or other material which gives a high coefficient of friction against the materials of which the construction elements 2,3 usually consist and have then been mounted so that its outermost layer 27 is completely flush with. or protrudes slightly outside the abutment surface of the side plate 9 against the construction elements 2,3. The magnet 11 may, for example, protrude one or a few tenths of a millimeter outside the side plate 9. Instead of providing the magnets 6,7,10,11 with a special, friction-giving layer, the base and side plates 4,5,7,8 can be coated with such a (not shown).
    The fixing of the permanent magnets 6,7,9 in the plates 4,5,8 11 is performed in the same way as the fixing of the magnet 11 in the side plate 9.
    When the fixing tool 1 is applied to a first structural element 3, the frictional force which is formed e.g. in the longitudinal direction between the structural element 3 and the underside of the fixing tool 1, carry significant weights and counteract forces arising from the weight of the structural element 2 to be joined to the structural element 3.
    A further aspect of the invention demonstrates a method of attaching structural members 2,3, such as steel studs / profiles. In a first step, the structural elements 2,3 are cut so that the desired angle between them can be obtained at the final joining, after which the fixing tool 1 is placed against the first structural element 2 in the area of the desired connection of the second structural element 3. One leg 1a of the fixing tool 1 is attached to said first construction element 2 by means of the magnets 6,7 which are inserted into the base and side plates 4,8 of the fixing tool 1 and are held in position by the traction force of the magnets 6,7 and the frictional force between the base and side plates 4,8 of the fixing tool 1 and the construction element 2 .
    The second leg 1b of the fixing tool 1 is attached to the second construction element 3 in a corresponding manner and in the intended position opposite the first construction element 2, after which the construction elements 2,3 can be joined in a first phase by spot welding or with a screw after which the fixing tool 1 can be removed with simple handles and the joining is completed by welding the joint around or by additional screws reinforcing the joining. The construction of the fixing tool 1 allows that in special cases it is possible to further strengthen the fixing of the tool to the construction elements 2,3 by means of screw clamps. In some cases also the alternative design of the fixing tool 1 with angle measuring means 21 for adjusting the angle, and locking the angle, between the legs 1a, b of the fixing tool 1 can further facilitate the fitting of the fixing tool 1 to the construction elements 2,3.
    The invention is of course not limited to the above-mentioned embodiments, but also other variants of the invention are possible and conceivable within the scope of the inventive concept and the scope of protection of the following claims.
    Thus, the magnetic elements 6,7, 10, 11 may be magnetic tapes or the like which are glued or otherwise applied to the side of the plates 4,5,8,9 facing the construction elements 2,3. It is also possible to apply a friction layer 27 of a high friction material to the plates 4,5,8,9 themselves on the side facing the structural elements 2,3 in use. The friction layer 27 can be placed on the entire surface of the base or side plates 4,5,8,9 or only on a part of their surface.
