[0002] Steel-concrete structure is a mixed structure of steel and concrete, and its structural materials mainly include steel, steel bars and concrete. This type of structure includes a frame-core tube structure composed of an outer steel frame or steel-concrete, steel tube concrete frame and a reinforced concrete core tube, and a tube-in-tube structure composed of an outer steel frame or steel-concrete, steel tube concrete frame tube and a reinforced concrete core tube. In construction, in order to improve construction efficiency, steel-concrete structure is usually formed and then hoisted to a designated location for assembly.
[0003] The commonly used lifting method at present is to use a rope loop to bind and fix the two ends of the steel-concrete structure and then lift it through a crane. However, since the rope loop tied to the steel-concrete structure is flexible, during the lifting process, if the steel-concrete structure shakes greatly due to external factors, the rope loop will slide, making the steel-concrete structure unbalanced and greatly skewed, making the steel-concrete structure prone to falling, which can easily cause damage to the connection of the steel-concrete structure and pose a safety hazard.

An adjusting rod 11 is fixedly connected to the side, and the outer surface of the adjusting rod 11 contacts the outer surface of the hook plate 8. A hook seat 9 is fixedly connected to the top of the adjusting plate 1 and located at the center position. One side of the hook plate 8 is clamped with the bottom end of the hook seat 9. Among them, by setting the connecting rod 5, it can shrink when pulled, so as to control the distance between the clamping sleeves 4 and achieve the clamping and fixing effect. By setting the hook plate 8 and the hook seat 9, the connecting rod 5 can be limited to achieve the effect of automatic unloading and fixing. By setting the hook rod 6, the bottom plate of the steel-concrete structure can be dragged to achieve lifting.
[0022] like Figure 1-4As shown, the interiors of the four clamping sleeves 4 are respectively slidably connected with the outer surfaces of the four hook rods 6, and a plurality of fixing through holes 15 are penetrated on one side of the four hook rods 6. The outer surfaces of the four clamping sleeves 4 are penetrated and inserted with fixing bolts 16, and the outer surfaces of the fixing bolts 16 are inserted with the interiors of the fixing through holes 15. By providing the fixing through holes 15, the hook rod 6 can be fixed by cooperating with the fixing bolts 16. By providing a plurality of fixing through holes 15, the elongation of the hook rod 6 can be adjusted to realize the lifting of steel-concrete structures of different sizes.
[0023] like Figure 4 As shown, both side walls inside the two square through holes 3 are provided with limiting grooves 13, and both sides of the four clamping sleeves 4 are fixedly connected with limiting blocks 14. The outer surfaces of the eight limiting blocks 14 are slidably connected with the inner surfaces of the four limiting grooves 13 respectively, which can limit the clamping sleeves 4 to prevent them from being skewed and improve stability.
[0024] like Figure 2 and Figure 3 As shown, two positioning grooves 10 are provided on one side of the hook seat 9, and two positioning plates 12 are fixedly connected to the outer surface of the hook plate 8. The outer surfaces of the two positioning plates 12 are movably plugged into the two positioning grooves 10 respectively to position the hook plate 8.
[0025] like Figure 1 , Figure 2 and Figure 3 As shown, four positioning sleeves 18 are fixedly connected to the top of the adjustment plate 1, and positioning rods 19 are slidably connected inside the four positioning sleeves 18. One end of the four positioning rods 19 is fixedly connected to the bottom end of the lifting plate 2, which can improve the overall structural strength.
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, a limiting plate 20 is fixedly connected to the bottom end of the lifting plate 2 and near the four corners, and movable plates 21 are slidably connected inside the four limiting plates 20.

By providing the elastic anti-skid pad 17, the friction between the clamping sleeve 4 and the steel-concrete structure can be increased, thereby improving the gripping force.
[0028] The utility model provides a steel-concrete structure assembly hoisting construction device, the specific working principle is as follows:
[0029] The adjustment plate 1 is lifted to the top of the steel-concrete structure, and the adjustment plate 1 is in contact with the top surface of the steel-concrete structure. The lifting plate 2 is pressed down under the action of gravity, driving the adjustment block 7 and the hook plate 8 to descend. During the descent, the adjustment block 7 rotates and drives the adjustment rod 11 to move and push the hook plate 8 to fall off from the inside of the hook seat 9, thereby releasing the restriction on the connecting rod 5. Then, the lifting plate 2 is lifted by a crane. During the rising process of the lifting plate 2, the two connecting rods 5 are driven to rise and the four clamping sleeves 4 are pulled to contract inside the square through hole 3 to clamp the two sides of the steel-concrete structure. The hook rod 6 hooks the bottom of the steel-concrete structure to quickly fix the steel-concrete structure. Due to the weight of the steel-concrete structure itself, the connecting rod 5 is further stretched, so that the clamping sleeve 4 fixes the steel-concrete structure more tightly. After the steel-concrete structure is placed in the specified position, the lifting plate 2 drops again and drives the adjustment block 7 and the hook plate 8 to move. The bottom of the hook plate 8 slides on the surface of the hook seat 9 and is engaged with the hook seat 9 to limit the connecting rod 5 and complete the unloading. When it is necessary to lift steel-concrete structures of different sizes, adjust the length between the hook rod 6 and the clamping sleeve 4, and then adjust it to a size matching the steel-concrete structure through the fixing through hole 15 and the fixing bolt 16, so as to realize the lifting of steel-concrete structures of different sizes.
