High-speed maglev prestressed track board and construction method thereof
The invention discloses a high-speed maglev prestressed track board and a construction method thereof, and belongs to the technical field of maglev tracks. The high-speed magnetic levitation prestressed track board comprises a track board body of a rectangular structure, and M longitudinal prestressed steel bars are arranged in the track board body. The functional areas are arranged on the two sides of the track plate in the longitudinal direction; wherein N vertical through holes are formed in the track plate, adjusting mechanisms for conducting prestress control on the transverse prestressed steel bars are arranged in the vertical through holes, and the adjusting mechanisms are connected with the functional areas on the two sides through the transverse prestressed steel bars. The adjusting mechanism has the advantages that based on the requirement of the high-speed magnetic levitation prestressed track board for transverse prestress, the adjusting mechanism can be used for conveniently applying prestress to the transverse prestressed steel bars, so that the prestress of the transverse prestressed steel bars meets the high-standard requirement of the high-speed magnetic levitation track board all the time; the high-speed magnetic levitation prestressed track board adopts a transverse and longitudinal bidirectional prestressed design; the track plate can better disperse and absorb stress when bearing an external load.
本发明公开了一种高速磁浮预应力轨道板及其施工方法，属于磁浮轨道技术领域；高速磁浮预应力轨道板包括矩形结构的轨道板，在轨道板内设有M根纵向预应力钢筋；沿纵向设置在轨道板两侧的功能区；其中：在轨道板上开设有N个竖向通孔，在竖向通孔内设置有对横向预应力钢筋进行预应力控制的调节机构，所述调节机构通过横向预应力钢筋与两侧的功能区连接。本发明的优点是：基于高速磁浮预应力轨道板对横向预应力的需求，利用调节机构能够方便地对横向预应力钢筋施加预应力，使得横向预应力钢筋的预应力始终满足高速磁浮轨道板的高标准要求；高速磁浮预应力轨道板采用横、纵向的双向预应力设计；轨道板在承受外部载荷时能够更好地分散和吸收应力。
