METHOD bolted connections of parts and bolted connections NODE

摘要

1. A method for bolting parts on which the bolt is made of a rod and a support head separately, the rod is made of two sections: a cylindrical section with a thread deposited on one end of the rod and a spread portion - at the opposite end a support head is performed with a through hole, designed to accommodate the expanded portion of the rod, the rod is inserted into the hole of the head and the supporting parts produce compound by passing the rod through performed in said hole parts with followed by fitting and tightening the nut, wherein the extended rod section is performed by a sphere, and the surfaces of through holes bearing head is shaped cone, which fits over the entire height of the cone opening head the spherical surface of the widened portion of the rod, wherein the hole for the bolt rod into connected parts made of conditions provide a gap between the cylindrical surfaces of holes and positioned therein sterzhnya.2. A method according to claim 1, characterized in that the extended portion of the bolt rod operate spheres with a diameter D is at least 1,6d, where d - diameter of the rod, and with a truncated end of the widened portion perpendicular to its axis is not more than 1 / 3D, and support head operate minimum height 0,3D with a through hole having a side support surface of the head diameter d + 4 ... 5 mm, and the parameters of the elements are bolted to each other in the following relation, where D- diameter of the support surface of the head, h - the maximum height of the irregularities on the surface NOSTA compressible parts in the area supporting n
