[0023] Embodiment 1

[0024] A kind of large-span beam anti-toppling support, comprising:

[0025] Fixed rod 3, the front end of fixed rod 3 is provided with clamping groove 4, and clamping groove 4 is used for clamping and fixing the flange of I -beam;

[0026] Telescopic rod 9, the first end of which is rotatably connected to fixed rod 3, and the second end is hinged to fixed plate 10, which is used to fix the web of the I-beam.

[0027] This utility model places a large-span I-beam 1 steel beam on sleepers 2, and sets multiple anti-tipping supports at intervals along both sides of the large-span steel beam. The flanges of the I-beam are clamped and fixed by fixing rods 3, and the web of the I-beam is fixed by telescopic rods 9. The support 8 is fixed to the ground, so that the I-beam 1 steel beam is effectively supported and more stable, and is not easy to tip over.
