RISALITA FOR RECONSTRUCTING BUILDING Russian patent published in 1996 - IPC

FIELD: civil engineering. SUBSTANCE: lean-to represents a risalita of story spatial blocks installed one on top of the other. The blocks are attached to building 2 and have face-surface wall 3 and lateral walls 4 and floor 5. Each member is made in the form of a whole spatial pre-fabricated block. Lateral walls 4 of the block have bevels 6 in the upper part to be used as guide, and wedge-type projections 7 in lower part. Contact surfaces of latter are parallel. Such wall structure allows one to provide high accuracy in installation and self-stopping blocks in design position without use of any additional equipment. Wedge-type projections 7 of the block being installed provide self-stopping spatial block in the design position and additionally squeeze wall 2 of the building being reconstructed in the process of assembly when moving along guide bevels of lateral walls 4. EFFECT: one can reduce significantly manual labour, increase technological efficiency when assembly, increase productivity, simplify installation, improve stiffness of the building. 3 dwg
