Referring to fig. 1 to 3, it is shown that the cantilever steel beam is fixed using the turnable double-rib cantilever steel beam fixing device, and the cantilever steel beam in this embodiment is an i-beam. According to the utility model discloses a girder steel fixing device encorbelments comprises elastic snap ring 6 etc. of double-ribbed snap ring 2, L shape connecting rod 3 and the 3 tip of L shape connecting rod. Double-rib snap ring 2 comprises two vertical parallel U-shaped vertical arm muscle 2-1 and two horizontal parallel gluten 2-2 for block girder steel 4 from girder steel 4 top. Each U-shaped vertical arm rib 2-1 is vertically connected with one end of the two gluten bars 2-2 at the same side. The length of gluten 2-2 is greater than the width of girder steel 4, and the U-shaped top of founding wall muscle 2-1 is equal to the sum of girder steel height, concrete floor thickness and 3 diameter three of L shape connecting rod to the height of bottom for when girder steel fixing device encorbelments when fixed girder steel 4, can be fully with girder steel 4 chucking. One end of the L-shaped connecting rod 3 is bent into an L shape, so that the L-shaped connecting rod 3 can be clamped on the vertical wall rib 2-1 to clamp the steel beam 4 from the bottom, and the L-shaped connecting rod 3 can be used as a handle for pulling the L-shaped connecting rod 3; the other end is provided with two blind holes 8, and the blind holes 8 are internally used for installing the elastic snap ring 6 with the gap. An opening above the U-shaped closed end of the two vertical wall ribs 2-1 penetrates through the L-shaped connecting rod 3 connected with the two vertical wall ribs 2-1, an elastic snap ring 6 is clamped in a blind hole 8 on the L-shaped connecting rod 3, and the L-shaped connecting rod 3 is prevented from moving left and right as shown in figure 5.
Adopt the utility model discloses a fixing device's advantage lies in, the double-ribbed snap ring can reuse, and the installation is simple with the dismantlement, and the cost of manufacture is low, and external influence factor is few, and application scope is extensive.
