Between the section of track, F steel section jointing structure is provided between the adjacent section of track connecting device of expansion joint position, and this structure not only needs to ensure between the section of track in vertical and horizontal installation alignment, also needs to the dilatation at expansion joint between the adaptation section of track simultaneously. Being big quantity research, Japan Patent JP2003184007A for these domestic and international multiple mechanisms, Chinese patent CN202509345U, CN103966928 are proposed the attachment structure of different types. Japan Patent JP2003184007A disclosed a kind of joint design preventing track dislocation in 2003, this structure is made up of the auxiliary connection of the outer lower limb end of the auxiliary connection under F shaped steel wing plate and F shaped steel, wherein F shaped steel wing plate is point cantact with auxiliary connection under plate, control the vertical and transversion malposition between the section of track by the auxiliary connection of the outer lower limb end of the design of F shaped steel wing plate low groove and F shaped steel, adapt between the section of track longitudinally opposite flexible by grooved hole. Chinese patent CN202509345U disclosed a kind of section of track connecting joint in 2012, this structure is made up of the outer magnetic pole key auxiliary connection matched with F shaped steel and wing plate auxiliary connection, is designed by " convex " font of wing plate auxiliary connection slide block or U shape and outer magnetic pole key auxiliary connection controls the vertical and transversion malposition between the section of track.Chinese patent CN103966928 disclosed a kind of medium-and low-speed maglev system track F rail joint design in 2014, this structure has the interior gathering sill of longitudinal extension, outer gathering sill on the inside bottom of two F shaped steel link wing rails, outside side wall, the opening of U-shaped connecting plate embeds the vertical and transversion malposition in two grooves to control between the section of track, U-shaped connecting plate has long slot bore, longitudinally opposed flexible to adapt between the section of track.
Although above attachment structure all can meet the connection request of the section of track in theory, but still suffer from attachment structure and adapt to the flexible not enough situation of section of track temperature.
Summary of the invention
Therefore, for the deficiency overcoming prior art to exist, the present invention provides one can effectively prevent adjacent two F shaped steel vertical and transversion malposition, improves the section of track medium-and low-speed maglev system F steel section jointing structure in the installation accuracy at rail gap place.
For solving above-mentioned technical problem, medium-and low-speed maglev system F steel section jointing structure of the present invention includes wing plate lower connecting plate, clamping plate, outer lower limb side connecting plate and two are provided with interior lower limb, outer lower limb, the F shaped steel of web and wing plate, the two ends of described wing plate lower connecting plate are connected with the wing plate of both sides with clamping plate respectively through the first bolt, described outer lower limb sidewall is provided with the groove along circuit longitudinal extension, described outer lower limb side connecting plate is provided with long slot bore in the side near clamping plate, described outer lower limb side connecting plate is provided with circular hole in the side away from clamping plate, described outer lower limb side connecting plate is bolted in groove by second.
Beneficial effects of the present invention is as follows: 1, the present invention achieves the connection of adjacent two F shaped steel by wing plate lower connecting plate and outer lower limb side connecting plate, can effectively prevent adjacent two F shaped steel vertical and transversion malposition, improve the section of track installation accuracy at rail gap place.
2, the present invention adapts to expansion joint telescopic displacement under TEMPERATURE FORCE effect between adjacent two sections of track.
3, present configuration is simple, processing cost is low, easy for installation, for ease of maintenaince.
After reading in conjunction with the accompanying the detailed description of embodiment of the present invention, the other features and advantages of the invention will become clearer from.
