JOINING MEMBER Russian patent published in 2000 - IPC

FIELD: construction engineering. SUBSTANCE: joining member can be used as anchoring component for joining wall panels, brick walls, etc. Joining member is made up of central rod and end anchoring parts which are manufactured from unidirectional mineral fibers impregnated in hardening polymeric binding agent. Anchoring parts are provided with insert made of unidirectional fibers impregnated in hardening polymeric binding agent or it can be made of ceramic material. Number of continuous fibers in any lateral cross-section over entire length of joining member is constant. In end anchoring parts, fibers are located over periphery of insert. Central rod is provided with locking limiter, which can be manufactured from porous elastic plastic material. In function of binding agent it is possible to use mixture of liquid and hard epoxy resins, or vinylether binding agent can be employed. Acceptable in function of unidirectional fibers is cord fabric with ratio of weft and warp respectively from 1:20 to 1:40. Surface of joining member in anchoring parts can have lateral flutes of 0.1-0.5 mm depth. Insert can be made of taper-cylindrical configuration. Application of aforesaid embodiment of joining member allows for higher anchoring capacity together with retention of alkali-resistance characteristic. EFFECT: higher efficiency. 6 cl, 3 dwg
