Embodiment approach

[0051] As an embodiment of the present invention, the locking member 15 is a screw 21, and the axial center of the upper surface of the No. 1 nut 1 is provided with a No. 2 threaded hole 22, and the No. 2 threaded hole 22 is used for Cooperate with the screw 21; the screw 21 is used to make the steel wire rope 2 tighten the friction block 17 by cooperating with the second threaded hole 22; when the locking member 15 is a screw 21, the screw 21 can vertically straight movement, thereby driving the steel wire rope 2 to move in the vertical direction; when the screw 21 is screwed down, the steel wire rope 2 is in a loose state, and at this time, the elastic member 19 squeezes the friction block 17 to fasten the inner wall of the No. 1 nut 12; At this time, the bolt has the function of loosening; at the same time, the bolt is not easy to disassemble; when the screw 21 is turned upwards, the steel wire rope 2 tightens the friction block 17, so that the friction block 17 does not con...

Abstract

The invention belongs to the technical field of construction and in particular relates to a metro rail paving method. A detachable locking bolt adopted by the method comprises a first screw cap, a first screw and a first nut. The first screw and the first screw cap are coaxially and fixedly mounted on the bottom surface of the first screw cap, and the first screw cap is arranged on an outer layerof the first screw in a sleeving mode; a first through hole penetrating to the bottom surface of the first screw cap is formed in the bottom surface, far away from the first screw cap, of the first screw; a second through hole penetrating to the first through hole is formed in the upper surface of the first screw cap; a locking part is fixedly mounted on the upper surface of the first screw cap; and the other end of a steel wire rope penetrates a mounting plate, the first through hole and the second through hole and is connected to the locking part. By arranging a friction block and an elasticpart to extrude the first nut, the bolt is locked. By arranging the first screw to drive the steel wire to move in the vertical direction, the bolt is convenient to detach, and the using efficiency of the metro rail paving method is improved.

Description

technical field [0001] The invention belongs to the technical field of construction, in particular to a subway track laying method. Background technique [0002] With the continuous improvement of the level of urbanization in our country, urban transportation has entered a period of rapid development, but the contradiction of road congestion has become increasingly prominent, and the role of subways in urban rail transit construction has become more and more obvious. In recent years, various places have increased subway construction , as a modern way of transportation, the subway has been valued by the road administration planning and loved by the common people; but in the long-term use of the subway, the firmness of the track is an important factor affecting the use of the subway; Bolts; when the bolts are prone to loosening and falling off after long-term use, technical solutions such as expansion bolts and locking bolts have appeared in the prior art to solve the technica...
