Description

field of technology The invention describes a clamping tool with two clamping jaws, each of which has a head and each head has a contact surface. State of the art Such clamping tools are known in the prior art, for example in the form of spring clamps or toggle clamps. With such a tool, a clamping force can be applied to a workpiece by means of contacting the workpiece surfaces with the clamping surfaces. Means are provided by which a clamping force can be applied to the workpiece. These means can be a spring element with which the two clamping jaws can be subjected to a force directed towards each other. Such a spring clamp is used, for example, in the DE 200 01 498 U1 described. Furthermore, profile bodies, such as CD profiles, are known from the prior art, with which a ceiling covering can be suspended from a room ceiling. From the DE 10 2013 105 047 D 4 and DE 198 24 854 A1 Are there known methods by which the two brackets of a direct hanger, which can be attached to the ceiling with a mounting bracket, engage clamping elements to temporarily fix a U-shaped CD profile between the two brackets? The clamping elements actuate the brackets in the area of a contact surface where each bracket rests against one leg of the CD profile. The height of such a temporarily attached CD profile can then be aligned, for example, using a laser level. The CD profile is moved vertically until the U-shaped section of the CD profile lies in a horizontal plane. Summary of the invention The invention is based on the objective of providing a tool suitable for the temporary fixing of two strip-shaped bodies to the two diverging broad faces of a rectangular body. In particular, the tool should be suitable as an assembly aid for the temporary fixing of a CD profile or a wooden slat to two parallel brackets of a direct hanger. The invention also relates to a further development of a clamping jaw known per se, which is adapted to temporarily fix two elongated bodies, for example in the form of strips or the brackets of the previously described direct hangers, to another body, which, for example, has two mutually opposing contact surfaces that run parallel to each other. The fixing is intended to be such that the elongated bodies can be attached to the other body in the fixed position, whereby the relative position of the elongated bodies with respect to the other body can still be changed in the fixed position. The problem is solved by the invention specified in the claims. The dependent claims not only represent advantageous further developments of the invention specified in the dependent claims, but also constitute independent solutions to the problem. According to a first aspect of the invention, the mounting surface shall have a screw-in window. This screw-in window provides access to the surface of the elongated body, for example, the bracket of a direct hanger. Fasteners can thus be mounted through the screw-in window, enabling the elongated body, for example, the bracket, to be permanently connected to the other body, for example, a wooden batten or the U-shaped leg of a CD profile. Screws can be driven through the screw-in window using a screwdriver. The screws can be inserted through pre-existing holes in the elongated body, for example, in the bracket. Self-tapping screws are preferred, which are then screwed into the side wall of the other body, for example, the U-shaped leg of the CD profile. The shape of the screw-in window can be arbitrary. Preferably, however, the screw-in window has a rectangular shape. The screw-in window can also be formed by an angled slot, for example, an elongated opening. It is essential that the screw-in window is open both to the mounting surface and to the rear of the clamping jaw head. It must allow passage for a screw or a screwing tool. Preferably, the screw-in window has a width that is at least half the width of the mounting surface. The screw-in window may have a height that is at least half the height of the mounting surface. According to a second aspect of the invention, a web is to adjoin the contact surface. For the temporary fastening of the two elongated bodies to the other body, the clamping jaws are subjected to a force that forces the contact surfaces towards each other. In the operating position, the contact surfaces can therefore run parallel to each other. The web then extends from a The mounting surfaces are oriented towards the other mounting surface. According to the invention, this web should have a passage window, the passage window extending to the mounting surface. During temporary fixation, the elongated body, i.e., the bracket, can extend through this passage window. This results in the tool being fixed to the elongated body, i.e., the bracket of the direct hanger. Preferably, the passage window is closed all around, so that the tool can only be moved relative to the elongated body in the direction of extension of the two parallel elongated bodies.
