DETAILED DESCRIPTION

[0034] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0035] In the description of the present application, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. It should be understood that the terms "first", "second", etc. are used to describe various information in the present application, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, the "first" information can also be referred to as "second" information without departing from the scope of the present application, and similarly, the "second" information can also be referred to as "first" information.

[0036] As Figures 1 to 3As shown, the preferred embodiment of the embedded rail mounting seat of the present application comprises a first prefabricated beam 1, a second prefabricated beam 2 and a plurality of connecting rods 3: the upper end of the first prefabricated beam 1 is provided with a first rail receiving groove 11, the second prefabricated beam 2 is arranged in parallel and spaced apart with the first prefabricated beam 1, and the upper end of the second prefabricated beam 2 is provided with a second rail receiving groove 21; each connecting rod 3 is arranged in parallel and spaced apart between the first prefabricated beam 1 and the second prefabricated beam 2 along the length direction of the first prefabricated beam 1, specifically, the length direction of each connecting rod 3 is perpendicular to the length direction of the first prefabricated beam 1; the first end of each connecting rod 3 is screwed with the first prefabricated beam 1, the second end of each connecting rod 3 is screwed with the second prefabricated beam 2, and the thread rotation directions of the two ends of each connecting rod 3 are opposite; each connecting rod 3 is connected with a locking mechanism for fixing itself on the first prefabricated beam 1 and / or the second prefabricated beam 2. The connecting rod 3 not only can play the role of connecting the first prefabricated beam 1 and the second prefabricated beam 2, but also can adjust the distance between the first prefabricated beam 1 and the second prefabricated beam 2 by rotating the connecting rod 3, so that the distance between the first rail receiving groove 11 and the second rail receiving groove 21 is adjustable, which is convenient for adjusting the track gauge in the subsequent maintenance process of the embedded rail mounting seat; moreover, each connecting rod 3 is connected with a locking mechanism for fixing itself on the first prefabricated beam 1 and / or the second prefabricated beam 2, after the track gauge is adjusted in place, the connecting rod is fixed by using the locking mechanism, so that the track gauge is fixed.

[0037] Among them, there are many ways to implement the locking mechanism. For example, after the track gauge is adjusted into place, a fixing rod is welded on the outside of the connecting rod, and then the other end of the fixing rod is welded to the first precast beam or the second precast beam. When the track gauge needs to be adjusted during maintenance, the end of the fixing rod can be cut off; in this embodiment, the first end of each connecting rod 3 is provided with a first threaded section 31 screwed to the first precast beam 1, and the first end of each connecting rod 3 is provided with a second threaded section 32 located outside the first precast beam 1, and the thread rotation direction of the second threaded section 32 is opposite to that of the first threaded section 31. The outer side of the second threaded section 32 is screwed with a first clamping sleeve 41, and each first clamping sleeve 41 is in contact with the first precast beam 1 at one end facing the first precast beam 1. Specifically, the rotation direction of the second thread segment 32 is opposite to that of the first thread segment, and the end of the first compression sleeve presses against one side of the first precast beam. When the connecting rod 3 is loose, the movement direction of the first compression sleeve 41 is opposite to the movement direction of the first precast beam 1. Since the end of the first compression sleeve presses against one side of the first precast beam, when the first precast beam moves toward the middle of the connecting rod 3, the first compression sleeve 4 will move toward the direction close to the first precast beam 1. At this time, the first compression sleeve 4 and the first precast beam 1 will interfere with each other, thereby preventing the first precast beam 1 from moving toward the direction close to the second precast beam 2. Therefore, the first compression sleeve 4 can play a role in preventing the connecting rod 3 from loosening. In addition, the end of the first compression sleeve 41 abuts against the side wall of the first precast beam 1. By judging the degree of fit between the end of the first compression sleeve 41 and the side wall of the first precast beam 1, the verticality of the first precast beam 1 and the connecting rod 3 can also be judged, and the parallelism between the first precast beam 1 and the second precast beam 2 can be indirectly judged. In this embodiment, as Figure 2 As shown, the connecting rod 3 is provided with a first threaded segment 31, a second threaded segment 32, a connecting segment 33, a third threaded segment 34 and a fourth threaded segment 35 in sequence from the first end to the second end. The fourth threaded segment 35 is screwed to the second precast beam 2. The outer side of the third threaded segment 34 is screwed with a second compression sleeve 42. The second compression sleeve 42 abuts against the side wall of the second precast beam 2 toward one end of the second precast beam 2.

[0038] To facilitate the installation of the first compression sleeve 41, in this embodiment, the inner diameter of the first compression sleeve is larger than the outer diameter of the first threaded segment 31; further, the inner diameter of the second compression sleeve 42 is larger than the outer diameter of the fourth threaded segment 35; specifically, before connecting the connecting rod 3 to the first precast beam 1 and the second precast beam 2, the first compression sleeve 41 is first passed through the first threaded segment 31 and then screwed to the outside of the second threaded segment 32, and the second compression sleeve 42 is passed through the fourth threaded segment 35 and then screwed to the outside of the third threaded segment 34, which facilitates the installation of the first compression sleeve 41 and the second compression sleeve 42, and facilitates the adjustment of the degree of compression of the first compression sleeve 41 on the first precast beam 1 and the degree of compression of the second compression sleeve 42 on the second precast beam 2.

[0039] In the embodiment, the first embedded part 51 is embedded at the position opposite to each connecting rod 3 of the first precast beam 1, each first embedded part 51 is provided with a threaded hole matched with each connecting rod 3, and the end of each first embedded part 51 facing the outer side of the first precast beam 1 abuts against the end of each first pressing sleeve 41. Since the first precast beam 1 is a concrete beam, the end of the first pressing sleeve 41 abuts against the end of the first embedded part 51, which can avoid the concrete from being broken due to the end of the first pressing sleeve 41 pressing on the concrete surface, and avoid the locking failure of the first pressing sleeve 41 to the connecting rod 3 caused by the broken concrete. In the embodiment, the second embedded part 52 is embedded at the position opposite to each connecting rod 3 of the second precast beam 2, and the second section of each connecting rod 3 is screwed with the second embedded part 52, and the end of each second pressing sleeve 42 abuts against the end of each second embedded part 52.

[0040] In order to improve the connection strength of the first embedded part 51 in the first precast beam 1, in the embodiment, one end of each first embedded part 51 in the first precast beam 1 is fixed with a first anti-pulling part 511 and a second anti-pulling part 512 arranged crosswise with the first anti-pulling part 511. Further, one end of each second embedded part 52 in the second precast beam 2 is fixed with a third anti-pulling part and a fourth anti-pulling part arranged crosswise with the third anti-pulling part.

[0041] In the embodiment, in order to facilitate the transportation of the first precast beam 1 and the second precast beam 2, the embedded track mounting seat includes two lifting rings, and each lifting ring is fixed with a screw rod part for being inserted into the threaded hole of the first embedded part 51. The screw rod part is installed in the threaded hole of the first embedded part 51, and the lifting rope or hook of the lifting device is inserted into the lifting ring to lift the first precast beam 1. That is, in the embodiment, the threaded hole of the first embedded part 51 not only plays a connecting role with the connecting rod 3, but also plays a connecting role with the lifting ring, thereby facilitating the lifting of the first precast beam 1.

Specifically, by controlling the thickness value of the lateral adjusting pads 71 located on both sides of the embedded track mounting base, the transverse position of the embedded track mounting base in the mounting groove 61 can be adjusted, the first and second precast beams 1 can be moved away from each other by the rotating connecting rods 3 to ensure that the distance between the first and second precast beams 1 is appropriate, so that the distance between the first and second rail receiving grooves 11, 21 meets the gauge requirement, and the first and second precast beams 1 can press the lateral adjusting pads 71 located on both sides of the embedded track mounting base respectively, so that the embedded track mounting base can be stably clamped in the mounting groove 61; the two side groove walls of the mounting groove 61 can apply a constraint to prevent the distance between the first and second precast beams 1 from increasing, and the first and second pressing sleeves 41, 42 can apply a constraint to prevent the first and second precast beams 1 from moving closer to each other, so that the distance between the first and second precast beams 1 remains stable; when the gauge needs to be adjusted, only the thickness of the lateral adjusting pads 71 needs to be adjusted, and then the distance between the first and second precast beams 1 can be adjusted by rotating the connecting rods 3. In the embodiment, the support foundation is a concrete foundation poured at the bottom of the tunnel segment 8.
