CONNECTION METHOD FOR COMPOSITE STRUCTURES AND UNITS Russian patent published in 2005 - IPC

FIELD: building, particularly connections specially adapted for particular building parts or for particular building structures and units.

SUBSTANCE: method involved using embedded members made as metal cylindrical cartridges arranged in concrete body of units to be connected in joint area thereof and metal connection member. Cylindrical cartridge interior is previously filled with adhesive composition. One end of connection member is placed in metal cartridge of the first unit to be joined, another end is inserted in that of the second one. Flange is welded to metal cartridge end. Flange is bored at 40° - 50° for the depth of 0.5 - 0.7 of flange thickness and conical flange bore passes into cylindrical one having dimension corresponding to metal connection diameter, which forms fixing clawing funnel. Ratio between inner cartridge diameter and connection member diameter is equal to d_c,in/d_cm = 1.5 - 2.0, where d_c,in is inner cartridge diameter, d_cm is metal connection diameter. Wherein resting outline is formed in area of metal cartridge abutment to flange. Resting outline has ledge of not less than 5 mm when connection member diameter is 10 - 30 mm, which prevents shear deformation development, increases squeezing degree and blocks metal connection. Cartridge has length L_c = (10-12)·d_cm, which prevents slip of metal connection.

EFFECT: simplified assemblage technology.
