Efforts in the tension elements 6, acting through the fixing device 5, pull the trim panel 4, giving it a design position. When uploading walling pitched part of the load creates in the longitudinal elements I and 2 operating torque and reactive efforts in the tension elements 6, which by means of the fixing device 5, the lower casing 4 is transmitted to the brackets 7, and using the latter in the longitudinal members 1 and 2 are additional torques opposite operational. The transverse elements 3 together with the longitudinal members 1 and 2 provide geometric immutability of the cladding holes 8 in the longitudinal element rolling part 2 serve for the passage of the tension elements 6 for ease of connection with them by means of the clamping device 5 and the brackets 7.In the proposed technical solution torques generated from the tension of the tension elements and the reactive forces in the elements of tension reduce operating torque, which allows you to refuse the transverse elements in the passage and intermediate the longitudinal element, and this has led the local imperfections (pagibig). The locking device can be performed over the entire length of the building envelope or individual elements installed discretely, and connected with the casing, for example, by welding.
