REINFORCING-SHEATHING BLOCK Russian patent published in 1995 - IPC

FIELD: construction. SUBSTANCE: reinforcing- sheathing block has vertical girder chords and horizontal webs for inner sheathing plates formed as trays with sides fixed in hermetically sealed relation to vertical and horizontal edges of joined inner sheathing plates. As a result hermetically sealed cavity system is formed. In emergency leakage occurred in the areas of joint welding of inner sheathing plates may be easily eliminated without interrupting operation of atomic power plant by using hermetically sealed cavities. EFFECT: improved strength and tightness of joint connections of fixed sheathing plates, enhanced reliability in operation of blocks and specific constructions of atomic power plants. 5 dwg
