Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1 to 3, a steel plate longitudinal slope adjusting device for a box girder embedded support comprises a bottom plate 1, and a first vertical plate 2 and a second vertical plate 3 on two sides of the bottom plate 1, wherein support columns 4 are symmetrically arranged on the upper end surface of the bottom plate 1, close to the first vertical plate 2; a first flat plate 5 is arranged at the upper end of the supporting column 4; studs 6 are symmetrically arranged on two sides of the middle of the upper end surface of the first flat plate 5; a screw 7 is arranged on the stud 6 in a penetrating way; a rotating rod 8 is arranged at one end of the screw rod 7 penetrating out of the bottom surface of the first flat plate 5, and a second flat plate 9 is arranged on the top side of the screw rod 7; two vertical gaps 10 are formed in the side wall of the first vertical plate 3 corresponding to the two sides of the second flat plate 9; bolts 11 penetrate through two sides of the second flat plate 9, and fastening nuts 12 are arranged at one ends of the bolts 11 penetrating through the gaps 10; the top of the second vertical plate 3 is rotatably connected with a top plate 13; the free end of the top plate 13 is erected on the second vertical plate 3; two support columns 4 are arranged; four studs 6 are provided.
