DETAILED DESCRIPTION OF THE INVENTION

[0020] FIGS. 1, 2 and 4 show a vertical lath A that includes cross laths C screwed down thereon wherein the vertical lath A contacts an insulation layer B of a roof or a faade wall.

[0021] The known sliding formwork brick 1 illustrated in FIG. 1 includes a plate 2 wherein upper and lower rectangular reaction bearings 3 and 4 are formed at a back side of the plate 2. The upper bar shaped reaction bearing 3 is supported in a contact line on the cross lath C. The cross lath C includes two side surfaces that are arranged at a right angle relative to each other and a side surface Cl oriented at a slant angle and forming a contact surface for the back side of the plate 2.
