REINFORCING MEMBER FOR REINFORCEMENT OF HEAT-INSULATING WALL STRUCTURES AND METHOD OF ITS PRODUCTION Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: in reinforcing member intended for reinforcement of heat-insulating wall structures, anchor hooks are made in the form of tapered thickenings of oval cross-section with subsequent lengths or constant or reduced cross-section. Value of large axis of oval cross-section increases from d to 1.5d. Value of small axis is at least not less than d, where d - diameter of load-bearing stem. Angle of tapered thickening in plane of large axis is equal to 3-10 deg as to axis of load-bearing stem. Length of subsequent section with constant or reducing cross-section is equal to 15-20% of length of anchor hook. Supporting flange of bush is made at angle of 45-90 deg with respect to longitudinal axis of bush. In production of reinforcing member, at first stage strands of glass fibre impregnated in polymeric binding material are drawn through compressing die so as to form continuous pipe. External diameter of this pipe is equal to maximal dimension of tapered thickening of anchor hook. At inlet to compressing die, inserted into pipe being formed through distance determined by length of load-bearing stem of reinforcing member is embedded member which determines configuration of dual anchor hooks of subsequent and preceding load-bearing stems of reinforcing member. At second stage, circular threads are placed with tension so as to make pipe together with embedded parts in the form of continuous stem with alternating dual anchor hooks. Finishing operation consists in cutting hardened stem across middle of dual anchor hooks. Application of aforesaid method and procedure increases load-bearing capacity of reinforcing member together with prolonging service life of building structures and widening area of use. EFFECT: higher efficiency. 4 cl, 2 dwg
