In the present embodiment, the length of the beam B12 is 12.076m; the length of the longitudinal beam A11 is 24.88m; the number of the longitudinal beams C13 is three; the width of each plate 3 is 18.6cm; the width of the longitudinal positioning chute 4 between two adjacent flat plates 3 is 14mm; the difference in length between any two beams D14 is not more than 20cm.
3 longitudinal beams C13 are arranged between two opposite end surfaces of the two cross beams B12, and a cross beam D14 is also arranged between the longitudinal beam A11 and the adjacent longitudinal beam C13 and between any two adjacent longitudinal beams C13; the cross member D14 is disposed along the central axis of the longitudinal member a11 in the width direction. In the embodiment, the longitudinal beam A11, the transverse beam B12, the longitudinal beam C13 and the transverse beam D14 all adopt 16-number I-steel; the longitudinal beam C13 and the transverse beam D14 are additionally arranged on the supporting framework 1 of the rectangular frame body structure, so that the bearing capacity of the device can be effectively improved, and the structure of the device is more stable; the joints of the cross beams and the longitudinal beams are connected through welding.
The slide assembly 5 includes a body bar 52 placed perpendicular to the width direction of the flat plate 3; the height of the main body bar 53 is 35mm and the length is 400mm; the transverse positioning chute 51 is opened at the top of the main body bar 52 and extends along the length direction thereof; and the cross section of the notch of the beam positioning chute 51 is T-shaped; convex plates 53 are provided on the front and rear sides of the main body bar 52 in the width direction thereof, respectively; the convex plate 53 is movably connected with the first sliding block 54 through bolts. Angle steel 2 is respectively arranged on the lower bottom surfaces of two adjacent flat plates 3 along the extending direction of a longitudinal positioning chute 6; the distance between the two opposite end surfaces of the two angle steels 2 is matched with the width of the first sliding block 54. In the present embodiment, the number of the convex plates 53 on the sliding assembly 5 is 4, and the convex plates are symmetrically arranged on the front end face and the rear end face of the sliding assembly; the cross section of the notch of the cross beam positioning chute 51 with the T-shaped structure can effectively prevent the rotary positioning assembly 6 from falling out of the notch along the height direction; the purpose of the angle steel 2 is to limit the degree of freedom of the first slider 54, preventing it from rotating below the slab, affecting the accuracy of the sliding assembly 5 along the longitudinal positioning chute 6.
