MESHY JOINT DISPLACEMENT SECTION AND METHOD FOR ITS MANUFACTURING Russian patent published in 2010 - IPC E04F13/08 B21D5/06 B21D47/02 B21D31/02 

FIELD: construction.

SUBSTANCE: invention refers to construction industry, and namely to manufacturing and design of meshy joint displacement profile. Specified number of notch groups rows is arranged along the whole width to comply with number of sections simultaneously produced from single stock, avoiding areas of solid metal at its edges, between rows and groups of notches. In each row of notch group notches are equal to length, parallel to each other and are arranged at the angle opposite to each other. Further longitudinal chutes are shaped. In the subsequent stands of profile-bending mill notches are drawn due to serial formation of two walls coupled along radius to the specified height, from sections of solid metal symmetrically to longitudinal axis of each row of notch group. At the same time rows of notch groups are transformed into meshy sections with cells in the form of parallelogram. After section walls have been produced with specified height, chutes are rolled until horizontally flat. Further longitudinal cutting of stock is carried out. Then arched shape is imparted to flat bases of sections by rolls of profile-bending mill, and sections are cut with the necessary length. Sections have two side walls of specified height coupled along radius, and arched notched-drawn bases that outgo from them towards opposite directions with rows of cells in the form of parallelogram arranged at the angle to longitudinal axis towards each other.

EFFECT: reduced consumption of metal.
