FIELD: construction.
SUBSTANCE: bolt connection includes a rail 1, attachable parts: the left pad 2 and the right pad 3, the bolt 4, track and a differential threaded connector 7 with the brake 10. The bolt 4 has the thread 5 with the pitch S and the tenon 6, matched to the same slot of the left pad 2. The differential threaded connector 7 has internal fine thread with the pitch S, conforming to the thread pitch 5 of the bolt 4, and from outside there is large thread 8 with the pitch S1 > S. From the outside on the differential threaded connector 7 the hexagon head 9 for standard key is provisioned. The brake 10 has a hole with the thread matching the thread 8 of the differential screw connector 7. The brake from the side of the right pad 3 has an outer cone 11 contacting with tapered hole of the right pad 3 with similar taper rate, and from the opposite side it has shaped section 12 for the special key. The brake 10 is screwed onto the entire length of the section of large thread of the differential threaded connector 7 up to tight contact 13 of end face planes.
EFFECT: improvement of reliability of the bolted connection.
