         5 . The construction plate according to  claim 1 , wherein the core layer is a honeycomb board, and wherein the honeycomb is manufactured from plastic material or from a paper mass. 
     
     
         6 . A construction plate according to  claim 1 , further comprising a support layer on the top side and a reinforcement layer on a bottom side, which is provided with a wide-meshed woven grid or a grid structure on the bottom side. 
     
     
         7 . The construction plate according to  claim 1 , wherein a coating mortar of a connection layer is poured on in liquid form, and is later leveled out and smoothed under the effect of the force of gravity so that it hardens in this form. 
     
     
         8 . The construction plate according to  claim 1 , wherein the basic material of the coating mortar of the connection layer is selected or mixed from lime mortar, gypsum mortar or cement mortar. 
     
     
         9 . The construction plate according to  claim 1 , wherein the basic material of the coating mortar of the connection layer is selected or mixed from loam or from gypsum for construction material. 
     
     
         10 . The construction plate according to  claim 1 , wherein the basic material comprises a commercially available filler admixture, a hardened reaction resin, preferably epoxy resin having 2 components. 
     
     
         11 . The construction plate according to  claim 1 , wherein the compressive strength of the connection layer, measured individually according to the DIN EN 13892 standard, is at least 25 N/mm 2 . 
     
     
         12 . The construction plate according to  claim 11 , wherein the compressive strength of the connection layer, measured individually according to the DIN EN 13892 standard, is between 30-50 N/mm 2 . 
     
     
         13 . The construction plate according to claim', wherein the connection layer can be coated with mortar adhering to tiles or with another adhesive material without leveling and smoothing. 
     
     
         14 . The construction plate according to  claim 1 , wherein the connection layer can be coated with: basic materials that do not contain a solvent; with paint coat materials; and with covering layers means without leveling and smoothing. 
     
     
         15 . The construction plate according to  claim 1 , wherein the non-woven glass fiber layer has a surface coating weight amount of 100 g/m 2  at the most. 
     
     
         16 . The construction plate according to  claim 1 , wherein the thickness of the transition mortar layer is between 0.1 and 2.5 mm. 
     
     
         17 . The construction plate according to  claim 1 , wherein the non-woven glass fiber layer is fully covered by the connection layer ( 7 ). 
     
     
         18 . The construction plate according to  claim 1 , wherein the non-woven glass fiber layer is fully covered by the connection layer with the exception of at least one part in the edge region of the construction plate.
