Embodiment Construction

[0041] The invention will be further described below in conjunction with specific embodiments.

[0042]

[0043] Such as figure 1 As shown, the track beam 400 laid along the track extension direction has a bottom mounting plate 401 made of metal material, and the bottom mounting plate 401 is welded and fixed to the track beam support plate 300 made of metal material or locked by fasteners. Several groups of track connecting structural members 100 are evenly distributed on the top of the pipe pile 200 to connect the track beam support plate 300 .

[0044] Such as Figure 2 to Figure 4 As shown, the rail connection structure 100 includes: a nut joint 1, a button barrel 2, a lower connecting rod 3, an upper connecting rod 4, a screw joint 5, a first fastening nut 6 and a second fastening nut 7. Among them, the nut joint 1 is embedded in the end of the pipe pile 200, and the nut joint 1 is tensioned and fixed by a rigid bar (such as a steel rod) embedded in the pipe pile 200....

Abstract

The invention discloses a connecting structure for a track, which comprises: a nut joint, which is embedded in the end of a pipe pile; a buckle barrel, which is screwed with the nut joint; and a lower connecting rod, whose lower end extends into the nut the upper connecting rod, whose upper end is detachably connected with the track beam support plate; and a screw joint, whose two ends are respectively screwed to the upper end of the lower connecting rod and the lower end of the upper connecting rod. This kind of connecting structure for the track indirectly realizes the installation height adjustment of the track beam support plate relative to the top of the pipe pile by adjusting its own assembly length, so as to solve the problem of inconvenient adjustment of the track beam laying height, and then improve the smoothness of the track surface laying.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a connection structure for rails. Background technique [0002] Pile foundations are usually composed of piles and pile caps connected to the top of the piles. If the pile body is completely buried in the soil and the bottom surface of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the cap is If the bottom is above the ground, it is called a high cap pile foundation. Regardless of whether it is a low-cap pile foundation or a high-cap pile foundation, for track or building construction operations, pile foundation construction is a relatively important construction link. [0003] It is usually difficult to ensure that the height of each pile body is even during the pile foundation construction operation. Moreover, since track projects usually take several months or years, for pile foun...
