METHOD FOR MANUFACTURE OF SANDWICH STRUCTURES Russian patent published in 1995 - IPC

FIELD: construction. SUBSTANCE: method for manufacture of sandwich structures is effected by application of filter of cementing strips 2 on opposite sides of strip billets 1. Two cementing strips are arranged on each billet along its longitudinal edges and width "a" of each billet equals sum of required thickness H of filler in three-layer structure and double width "b" of cementing strips. Strip billets 1 are laid between two sidings 3 and 4 parallel to each other and spaced at interval "t" not less than width "b" of cementing strip 2. Cementing strips are arranged in staggered order in plane of cross-section of package. Billets 1 are joined with sidings 3 and 4 in places of application of cementing strips 2, and then, sidings are separated by longitudinal displacement of one relative to the other in direction square to cementing strips by displacing edges of each billet towards each other, and value B of displacement is equal to width "a" of billet 1 reduced to thickness δ and double width "b" of cementing strip 2. Produced three-layer structure is subject to fixation. EFFECT: higher efficiency. 2 dwg
