Construction monitoring device, construction monitoring method, construction monitoring system and construction practice system for seal and storage medium

The invention relates to a construction monitoring device, a construction monitoring program, a construction monitoring method, a construction monitoring system and a construction practice system for a seal and a storage medium. According to the construction monitoring device for a seal, during construction of a seal, the seal is clamped into a flange joint and fastened with a plurality of bolts for sealing. The construction monitoring device for a seal is provided with a pattern information generation unit, wherein the pattern information generation unit generates a plurality of coordinates extending radially from a center point; target axial force of the bolts or detected axial force of the bolts is represented by distances from the center point on all the coordinate; and a first distribution pattern based on the target axial force or a second distribution pattern based on the detected axial force is generated on the coordinates by connecting the target axial force or the detected axial force on the adjacen
