A METHOD FOR PREPARATION OF RECIPROCAL PRESSING SURFACE (21,22), OF SEGMENTS OF A CONTRUCTION (1), THIS CONTRUCTIONS (1) BEING ACHIEVED BY JUXTAPOSITION AND ASSEMBLY OF SUCH SEGMENTS (2) COMPRISING SUCH RECIPROCAL PRESSING SURFACES (21,22), REFERRED TO AS FIRST AND SECOND SURFACE (21,22), THIS METHOD INCLUDING A STEP ACCORDING TO WHICH, PRIOR TO ASSEMBLY OF THE SEGMENTS (2), A LAYER (3) OF A CONNECTING MATERIAL (4) IS APPLIED TO AT LEAST ONE OF SAID FIRST AND SECOND SURFACE (21, 22), THE FUNCTION OF WHICH CONNECTING MATERIAL IS TO CONSTITUTE A FLUID-TIGHT SEAL BETWEEN THESE FIRST AND SECOND SURFACES (21,22), ONCE ASSEMBLED, THIS METHOD BEING CHARACTERISED IN THAT -TO FORM A CONNECTING MATERIAL (4), A MATERIAL (4) IS SELECTED FROM AMONG CONNECTING MATERIALS WHICH ARE, IN ORDER TO OBTAIN GOOD CONNECTING CONDITIONS BETWEEN SURFACES, CURRENTLY RECOMMENDED FOR USE IN MAKING A THICK LAYER, BECAUSE OF THEIR DURATION OF HARDENING WHICH IS INVERSELY PROPORTIONAL TO THE VALUE OF THE THICKNESS OF THE LAYER, -PRIOR TO THE JUXTAPOSITION OF ONE SEGMENT (1) TO ANOTHER SEGMENT (1), AT LEAST ONE LAYER (3) OF THE SELECTED CONNECTING MATERIAL (4) IS APPLIED, BY SPRAYING, ON AT LEAST ONE OF THE SAID FIRST AND SECOND SURFACES (21,22) INTENDED TO CO-OPERATE, AND, DURING THE APPLICATION OF THIS LAYER (3), A THICKNESS (5) OF A MAXIMAL VALUE IS GIVEN TO THIS LAYER (3) SUCH THAT THE HARDENING OF THE CONNECTING MATERIAL (4) IS DELAYED AT LEAST FOR THE DURATION OF THE OPERATIONS OF JUXTAPOSITION AND POSITION ADJUSTMENT OF THE SEGMENTS (1), AND THIS IS SUCH A WAY AS TO ALLOW USE OF THIS CONNECTING MATERIAL (4) AS LUBRICATION AGENT BETWEEN THE SAID FIRST AND SECOND SURFACES (21, 22). |
