MODULE FOR MAKING CONCRETE ARTICLES, HOLLOW-CORE DEVICE, USE OF GRID FOR MAKING MODULE AND CONCRETE ARTICLE Russian patent published in 2019 - IPC E04B5/32 

FIELD: construction.

SUBSTANCE: invention relates to construction, specifically to a module for making concrete articles. Module comprises row (2) consisting of multiple cavities (100) fixed in grid frame consisting of at least two grids (10, 20) passing in longitudinal direction, planes of which are oriented across or under inclination relative to horizontal. Each of the grids has at least one first and one second longitudinal rods (11, 12; 21, 22), as well as multiple transverse rods (13, 23) connected to the longitudinal rods. At least one of the openings on the outer side has for each grid at least one first fixing device and at least one second fixing device (311, 321, 412, 422), which are located relative to each other so that both grates due to placement first longitudinal rod (11, 21) in first fixing device (311, 321) and placement of the second longitudinal rod (12, 22) in the second fixing device (412, 422) are fixed between fixing devices, at least with geometrical closure and with retention of all of void-forming agents (100).

EFFECT: technical result of invention is simplification of manufacturing.
