Reinforcement device and use of it in walls

Abstract

The invention relates to a reinforcement device for fastening, in this context, tremendous loads to particularly weaker walls of the type wallboard coated stud frame, and to contribute to the ability of walls to resist horizontal forces. The reinforcement device comprises portions, which connect and reinforce the parts of the wall construction. Thus, exceeding a materials tensile strength can be avoided, and the forces are distributed over a larger area, wherein the resistibility thereof can be summarised to a larger resistance. In a certain embodiment the reinforcement device can be used for fastening in solid constructions, such as light concrete and hollow brick constructions.

         6 . A reinforcement device according to  claim 1 , wherein said cylinder body ( 18 ) is reel-shaped and hollow. It is hollow to be surrounded by a wire cloth ( 27 ) and cast-surrounded with joint compound ( 26 ). The cylinder body is fastened in a rear portion thereof by the means of a glued joint ( 14 ) and a pin ( 22 ), and is guided and supported in a front portion thereof by a bordered surface ( 15 ), in a glued joint ( 25 ). The body ( 12 ) is provided with an aperture ( 16 ) for fastening means and, if the cylinder body is hollow, a reduction plug ( 21 ).  
     
     
         7 . A reinforcement device according to  claim 1 , comprising the device according to one embodiment, wherein the rear portion of the device is elongated ( 31 ), and comprises a movable part ( 34 ) on the cylinder body. Further, the cylinder body ( 32 ) and the portion filling the lead through ( 30 ) in the wallboard are included. The cylinder body ( 32 ), having its front portion ( 30 ) and its rear portion ( 31 ), provides a fixed unit. The unit is mounted in a rear portion thereof by the means of a glued joint ( 14 ) and a pin ( 22 ), and is guided and supported in a front portion thereof by a surface ( 15 ). Further, a glued joint ( 14 ) is included, which glues the movable part to the rear portion of the front wallboard. Further, a reduction plug ( 21 ) is included, having an aperture for fastening means ( 16 ) if the cylinder body is hollow, and a wire cloth ( 27 ) is included, wherein the device can be filled with joint compound. Further, the movable part is turned 180 degrees in relation to the fixed unit. Further, pull-strings ( 33 ) are included, which are attached to the movable part ( 34 ), and the use of these pull-strings to move the movable part and to rotate it along the cylinder body is included. Further, a lock for threading onto these pull-strings is included.  
     
     
         8 . A reinforcement device according to  claim 1 , comprising the device without the cylindrical intermediate portion. The rear plate ( 38 ) is rectangular, or essentially rectangular. The front plate ( 30 ), which can be provided with glue ( 25 ), is thread onto the pull-strings ( 33 ), which are fastened in the rear plate ( 38 ). The device can be turned in an optional direction in a full circle, or 380 degrees. The plate ( 28 ) is provided with glue ( 14 ). The front plate ( 32 ) is comprised by an elliptic front side and a circular back side.  
     
     
         9 . Use of a reinforcement device according to  claim 1  in connection with reinforcement of stud frame walls.  
     
     
         10 . Use of a reinforcement device according to  claim 1  in connection with reinforcement of more rigid walls, for example hollow brick walls or light concrete walls or the similar.
