A method of and wall sheet for building up a silo with lining and a method of manufacturing wall sheets for such a silo. The wall sheets are pre-formed wall sheets, comprising a base sheet and a sheet of lining material, bonded thereto in a slightly staggered manner. The lining material covers a number of bolt holes of the base sheet and already fitted in the covered bolt holes are fastening means, secured against rotation and also covered by the lining material. After the wall sheet has been mounted, free edge strips of the layer of lining material fall over uncovered edge zones of adjacent wall sheets. Connecting sheets of lining material are welded together along the edges, and, if necessary, the overlapping strips are bonded to the subjacent wall sheets.
A method of building up a silo or tank with a lining by means of pre-formed, substantially rectangular, wall sheets, connected to each other by means of screw connections for forming a complete silo wall, characterized in that wall sheets are used provided, along the edges thereof, with bolt holes, the bolt holes in zones located along at least two connecting edges being provided with fastening members secured against rotation, and the zones comprising said fastening members and the rest of each wall sheet being covered, on the inside thereof, by a layer of lining material bonded to the wall sheet, leaving free two other free edge zones provided with bolt holes, said layer of lining material extending by edge strips beyond the edges of the zones having bolt holes provided with fastening members, and that the wall sheets are fastened to each other by means of the fastening members and the bolt holes in a manner such that said edge strips of the layer of lining material of a wall sheet cover the free edge zones of two adjacent wall sheets, and that the adjacent edges of the layers of lining material of different wall sheets are sealingly bonded to each other.
A wall sheet for building up a silo or tank, comprising a pre-formed base sheet provided, along the circumference thereof, with rows of bolt holes, characterized in that on the inside of the silo to be built the wall sheet is provided with a layer of lining material, bonded to the base sheet, said layer of lining material leaving free the bolt holes along two connecting edge zones and covering the bolt holes along two other connecting zones, the covered bolt holes being provided with fastening means also covered by the layer of lining material and the layer of lining material, at the location of said other connecting zones, having free edge strips extending beyond the edges of the base sheet.
A passage element for mounting in an opening in at least one of a wall sheet of a silo or tank wherein said passage element, in mounted condition, has a flange adapted to abut against the wall sheet and provided with bolt holes wherein fastening members are adapted to fit, the flange being provided with lining material covering the bolt holes in the flange and having at least one edge strip extending beyond the circumferential edge of the flange, said edge strip adapted to bond to the lining material of the wall sheet.
