SEISMIC FIXTURE FOR T-SHAPED PART OF EXPANSION JOINT OF LATTICE STRUCTURE Russian patent published in 2013 - IPC E04B9/00 

FIELD: construction.

SUBSTANCE: fixture is designed to cover a longitudinal gap between a pair of sections of T-shaped parts of a lattice structure. The fixture has a cross-like shape in the horizontal projection, formed by a set of four non-detachable branches. Branches have the shape of the cross section in the form of the tilted "U" letter. The parts of the lattice structure have the shape of the tilted "T" letter with a hollow reinforcing bulge on their upper edge. One of branches has a longitudinal cut that accepts the fixture, and other ones - places for acceptances of fixtures. The cut and acceptance places accept the fixture and make it possible for the fixture to be fixed in the bulge of the T-shaped part. Remaining branches are placed so that they are fixed relative to sections of crossing sections of T-shaped parts with the help of fixtures. The cut is arranged so that the appropriate section of the T-shaped part of the lattice structure folds in telescopic manner inside the branch, whenever a non-standard force is applied to the section of the T-shaped part of the lattice structure.

EFFECT: improved resistance to collapse under seismic forces.
