Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Examples

A fixing device suitable for the assembly type installation of an overhanging steel structure comprises a steel beam clamp and a clamp connecting rod 1; as shown in fig. 1, the sheet metal steel plate that the girder steel anchor clamps adopt 20cm thick is made and is formed, including left anchor clamps 2 and right anchor clamps 3, left anchor clamps 2 include left splint 21, the lower extreme of left splint 21 is equipped with left C clamp groove 22, left C clamp groove 22 forms overall structure with left splint 21 welding, right anchor clamps 3 include right splint 31, the lower extreme of right splint 31 is equipped with right C clamp groove 32, right C clamp groove 32 forms overall structure with right splint 31 welding, be equipped with the wooden backing plate 4 between left splint 21 and the right splint 31, the three is connected through two sets of bolt assembly 5, the centre that lies in two sets of bolt assembly 5 on left splint 21 and the right splint 31 all is equipped with through-hole 6, two through-hole 6 mutual dispositions, as shown in fig. 2, 3, anchor clamps connecting rod 1 passes through-hole 6 and connects each girder steel anchor clamps, the both ends of anchor clamps connecting rod 1 all are equipped with fixed pin 7, fixed pin 7 is arranged perpendicularly with anchor clamps connecting rod 1.

In the embodiment, as shown in fig. 3, the cantilever steel structure 8 is connected to the ground by using a jig in a hoisting manner, the cantilever steel structure 8 is formed by splicing a tail end i-beam 81 and a cantilever end i-beam 82, and the beam clamps are arranged on the upper and lower flanges of the cantilever end i-beam 82 by using the left C-shaped clamping groove 22 and the right C-shaped clamping groove 32 and are connected and fixed by using the bolt assembly 5. Connect the girder steel anchor clamps of arranging on the edge of a wing with each end I-shaped girder steel 82 of encorbelmenting as whole through anchor clamps connecting rod 1, the both ends of anchor clamps connecting rod 1 all adopt fixed pin 7 fixed with girder steel anchor clamps, prevent anchor clamps connecting rod 1 drunkenness or roll. After the I-shaped steel beams 82 at the overhanging ends are connected and fixed through the fixing devices, the overall rigidity is high, the I-shaped steel beams are hoisted to a construction working surface by adopting an integral hoisting method, and after the I-shaped steel beams are firmly connected with a steel structure, the fixing devices on the I-shaped steel beams 82 at the overhanging ends can be detached.

The utility model discloses can avoid the high altitude to hoist section by section and encorbelment the end girder steel, improve the rigidity and the stability of the steel construction of encorbelmenting, guarantee whole hoist and mount's security, have that the construction is simple, ann tears open advantages such as convenient, safe and reliable, the steel construction installation accuracy of encorbelmenting is better.

The above is only the embodiment of the present invention, not the limitation of the patent scope of the present invention, all the equivalent structures made by the contents of the specification and the drawings are directly or indirectly applied to other related technical fields, all the same principle is within the patent protection scope of the present invention.
