FIELD: construction.
SUBSTANCE: invention relates to multiuse support structure for pillars, supports, masts or other lengthy objects based on anchor reversibly fixed in ground, inserted into ground or other base. Fastening device for fixation of lengthy object, having lower part of substantially permanent cross section, in its base comprises at least one extended clamping element with surface inverted inside, shape of which provides for possibility to locate it along and around part of specified lower part of object, and lengthy vessel having inner cavity, shape and dimensions of which make it possible to locate combination of at least one clamping element and specified lower part of object. Besides each specified at least one clamping element has upper and lower ends and surface inverted outside and narrowing in internal direction from specified upper end in direction towards specified lower end in the first part near specified upper end and in the second part near specified lower end, and inner cavity of vessel narrows in inner direction in according first and second parts, besides when using fastening device, pressure applied downwards to specified clamping element may create wedging contact between specified surface inverted outside and vessel near upper end and lower end. Also method is described for fixation of lengthy object in base, as well as method for removal of lengthy object fixed in base with application of fastening device.
EFFECT: development of simple and efficient device, which supports pillar, making it possible to withdraw pillar and periodically shift it, besides having minimum effect at site, when pillar is not installed.
