Device for basing welded trusses at testing on static and cyclic strength is arranged as upper movable pressing element and support with high rigidity, between those welded truss being studies is installed. Pressing element is arranged as equal-arm lever with semi-cylindrical rigid contact supports distance between which is equal to distance between the upper units of truss. Support has two lower semi-cylindrical supports with inter-axial separation that is equal to mounting length of truss, and two end supports one of which is fixed semi-cylindrical, second one is movable semi-spherical, installed on springy element. |
