in the figure: the device comprises a cross bar 1, a hanging ring 2, a sliding sleeve 3, a hook 4, a clamp 5, a threaded rod 6, a top block 7, a lifting lug 8, a threaded sleeve 9, a locking nut 10, an L-shaped hanging rod 11, a groove 12, an adjusting block 13, a supporting contact plate 14, a pin shaft 15 and section steel 16.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1, 2 and 3, the section steel lifting device for building construction comprises a cross rod 1 and a lifting ring 2 fixed in the center of the cross rod, wherein sliding sleeves 3 are symmetrically sleeved on two sides of the cross rod 1, the lower part of each sliding sleeve 3 is fixed with a clamp 5 through a hook 4, each clamp 5 consists of a threaded rod 6, a top block 7, a lifting lug 8, a threaded sleeve 9, a locking nut 10 and an L-shaped lifting rod 11, the threaded rod 6 is sequentially screwed with the locking nut 10 and the threaded sleeve 9 from top to bottom, the top of the threaded rod 6 is fixed with the lifting lug 8, the bottom of the threaded rod 6 is fixed with the top block 7, the two sides of the threaded sleeve 9 are hinged and fixed with the L-shaped lifting rods 11, the L-shaped lifting rods 11 are integrally formed by an inclined rod and the cross rod, a groove 12 is formed in the cross rod at the lower part of the L-shaped lifting rods 11, an adjusting block 13 is arranged in the groove 12, the, a supporting contact plate 14 arranged above the recess 12 is fixed to the top of the adjusting block 13.

The fixture 5 is fixedly connected with the hook 4 through the lifting lug 8, and the hook 4 is fixed with the sliding sleeve 3.

The contact surface of the upper part of the contact plate 14 is formed in a concavo-convex shape.

The sliding sleeve 3 and the cross rod 1 are arranged in a transition fit mode.

The working principle is as follows: when the utility model is used, the L-shaped suspender 11 at the lower part of the two fixtures 5 is propped open to enable the cross rod to enter the inner side of the section steel 16, and the supporting contact plate 14 on the L-shaped suspender is contacted with the upper part of the inner side of the section steel 16, the locking nut 10 is loosened to rotate the threaded rod 6 to move downwards to enable the top block 7 at the lower part of the L-shaped suspender to be contacted with and pressed against the upper part of the section steel 16, the locking nut 10 is rotated downwards to lock the threaded sleeve 9, so that the fixtures 5 firmly fix the section steel 16, the supporting contact plate 14 which can rotate is arranged at the inner side of the cross rod of the L-shaped suspender 11, so that the L-shaped suspender can be ensured to be closely contacted with the inner side of the section steel 16 when fixing different specification models, and can be ensured to be firmly fixed;
