PROTECTION SYSTEM FOR CONSTRUCTION STRUCTURES FROM OVER-STANDARD EXPLOSIVE, SHOCK AND SEISMIC EFFECTS Russian patent published in 2018 - IPC E04H9/02 E02D27/34 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction and can be used for protection and guarantee the vitality of building structures with repeated over-standard dynamic impacts. System comprises a support, its lower part is fixed on a support surface and is made of separate support plates. Support plates are designed to install steel collapsible inserts with cross sections in the form of rings and are installed in depressions made on the supporting surface. Depth of the recesses is equal to the total thickness of the support plate and the folded wall insert. Each support plate width is not less than πR, where R is the outer radius of the folded insert, and the length corresponds to the length of the folded insert. Foldable inserts are uniformly installed on the supporting surface, and their length is determined by the given dependences taking into account the outer radius of the folded insert, the thickness of its wall, resistance of the material and the current load. Additionally flat jacks are installed on the supporting surface, connected to the pump station Number of jacks is chosen according to the weight of the construction structure and the lifting capacity of the jack. For the installation of the jacks in the supporting surface, grooves are made, the depth of them corresponds to the working output of the piston to a height not less than the outer diameter of the collapsible insert.

EFFECT: protection system has a minimum readiness for repeated over-standard explosive, shock and seismic impacts, it eliminates the mobility of the foldable inserts under the influence of loads and, thereby, ensures maximum preservation of the performance characteristics of the building structure.
