In this way, the second guide member is inserted into or pulled out of the first guide member in the longitudinal direction of the track beam 1 so that the screeding structure 30 can be fitted to the guide rail 21. Illustratively, the size of the guide groove 104 in the height direction of the rail beam 1 is reduced to form a reduced area, taking a plane perpendicular to the longitudinal direction of the rail beam 1 as a projection plane. In this way, during the lateral movement of the guide platform 103 along the track beam 1, the part of the guide platform 103 with the size larger than the reduced area cannot be separated from the reduced area, so that the guide platform 103 is limited to be separated from the guide groove 104 along the lateral direction of the track beam 1. On the other hand, the guide groove 104 and the guide platform 103 are more stably matched, and the guide platform 103 is prevented from shaking in the guide groove 104.

The specific shape of the guide groove 104 is not limited, and in an exemplary embodiment, a plane perpendicular to the longitudinal direction of the rail beam 1 is used as a projection plane, and a projection pattern of the guide groove 104 is substantially T-shaped. In another embodiment, the projection pattern of the guide groove 104 is substantially gourd-shaped, taking a plane perpendicular to the longitudinal direction of the track beam 1 as a projection plane. In another embodiment, the projected pattern of the guide groove 104 is substantially polygonal or irregular, etc.

In one embodiment, the adjusting structure 40 is a plurality of adjusting structures 40, and the plurality of adjusting structures 40 are arranged at intervals along the longitudinal direction of the guide rail 21. A plurality of adjustment structures 40 to more precisely adjust the height of the guide rail 21 at different locations in the longitudinal direction.
