LEAVE-IN-PLACE FORM BLOCK Russian patent published in 2008 - IPC E04B2/86 

FIELD: construction.

SUBSTANCE: invention pertains to the construction field and may be used for construction of leave-in-place form for building external and internal solid-cast and heat insulating walls of multi purpose buildings and constructions without further coating. Leave-in-place form block consists of two concrete plates accommodating inserted female screws. Metal construction hooks engaged at the ears of plastic strainers are screwed into the female screws. Varying depth of hook screwing in adjusts upright position of plates placing. Usage of hooks of various thicknesses and consecutive connection of strainers makes possible getting forms for building up walls of various thicknesses. Plates may be manufactured with decorative coating heating layer making walls building much easier. Blocks in the same row are connected between each other by means of wire strainers. Blocks in neighboring rows are connected by plastic strainers. Form construction consists in its consecutive extension starting from the bottom row. Further rows are placed over the bottom one until reaching the required height. Metal reinforcement, embedded elements may be set into the space between the walls of the form in order to avoid slotting for laying of service lines and perforation of openings and doors at full thickness of the wall.

EFFECT: simplified assembly of the form; reduction of storage and transportation expenses; cost reduction of assembly works; possibility of preliminary assembly of heat insulating layers; possibility of usage of plates in the form as a ready for operation coating of the wall under construction; simplification of building walls of various thicknesses.
