Embodiment approach

[0051] As an embodiment of the present invention, the locking member 15 is a screw 21, and the upper surface of the first nut 1 is provided with a second threaded hole 22 at the axis position, and the second threaded hole 22 is used for Use with the screw 21; the screw 21 cooperates with the second threaded hole 22 to make the wire rope 2 tighten the friction block 17; when the locking member 15 is the screw 21, the screw 21 can move vertically in the second threaded hole 22 , Thereby driving the wire rope 2 to move in the vertical direction; when the screw 21 is screwed down, the wire rope 2 is in a relaxed state, and the elastic member 19 presses the friction block 17 to fasten the inner wall of the No. 1 nut 12 at this time; The bolt has a loosening function; at the same time, the bolt is not easy to disassemble; when the screw 21 is screwed upwards, the wire rope 2 tightens the friction block 17, so that the friction block 17 does not contact the inner wall of the No. 1 nut ...

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 field of construction technology, and specifically is a method for laying subway tracks. Background technique [0002] With the continuous improvement of the level of urbanization in China, urban transportation has entered a period of rapid development, while the contradiction of road congestion has become increasingly prominent. The role of subway in urban rail transit construction has become more and more obvious. In recent years, various places have increased subway construction. As a modern mode of transportation, the subway is valued by road administration planning and loved by the people; however, in the long-term use of the subway, the firmness of the track is an important factor that affects the use of the subway; such as the use in rail assembly Bolts; when the bolts are prone to loose and fall off after a long time of use, technical solutions such as expansion bolts and locking bolts have appeared in the prior art to s...
