FIELD: civil engineering; large prefab panel used in construction of various-purpose buildings and structures. SUBSTANCE: interior wall panel is made of thermally treated concrete mix and contains string-type reinforcement in the form of tensioned pieces extended over panel length and located in rows within panel thickness. Panel has slots 7,8,9 in its surface which are located both along its vertical ribs and along its horizontal ribs, and panel is also provided with internal anchors located in two rows within panel thickness, and remaining in concrete. Anchors are rectangular in shape and provided with supporting flats and they are interconnected inside panel thickness before its formation. Panels are joined through internal anchors and for this purpose bodies of internal anchors are provided with frontal internal anchors and for this purpose bodies of internal anchors are provided with frontal vertical protrusions having holes extending to panel slots. Connection of protrusions of internal anchors 5 is effected by additional connecting articles and their ribs are secured in anchor protrusions by means of pins and bolts with washers and nuts inserted into extended longitudinal and inline holes or into one vertical and other horizontal hole in plates of connecting articles. String reinforcement is made of endless line wound around internal anchors in double-axis direction and in two rows within panel thickness with rigid fastening of both ends of line on bodies of internal anchors so as to prevent creeping of concrete along metal reinforcement string.
