Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a steel cage hoisting structure. Background Art

[0002] In civil engineering construction, in the common high-rise building cast-in-place pile foundation structure steel cage hoisting construction, iron wire is usually used to tie the main reinforcement or spiral stirrups of the steel cage. This method has random and loose binding points, which can easily cause the steel cage to fall from a high altitude, posing a great safety hazard. Moreover, the steel cage cannot be guaranteed to be vertical after lifting, and it will be difficult for the crooked steel cage to enter the pile hole. After it is in place, the position of the steel cage cannot be guaranteed to be accurate, thus affecting the quality of the pile.

[0003] In the prior art, there is a method of using a fixing device for fixing the main reinforcement to connect the steel wire rope for lifting. The main reinforcement is clamped by the fixing device, and the fixing device is connected to the steel wire rope, so that the main reinforcement is connected to the steel wire rope. This lifting method is more reliable than the binding method with random binding points, but the fixing device is often unstable, which may cause the main reinforcement to slip out of the fixing device and cause the steel cage to fall from a high altitude.

[0006] The first connector and the second connector each include two arc-shaped fasteners, one end of the two fasteners are hinged to each other through a hinge rod, and the other end is provided with a connecting plate, and the connecting plate is provided with connecting holes. The connecting holes on the two connecting plates are arranged opposite to each other, and the two connecting plates are connected together by bolts.

[0007] One end of the connecting rod is hinged to the lifting ring.

[0008] The plurality of first fixing structures surround the outer periphery of the plurality of second fixing structures.

[0009] The steel cage hoisting structure also includes a blocking member, which is fixed to the main reinforcement. During hoisting, the blocking member, the first connecting member, and the second connecting member are fixed on the same main reinforcement from top to bottom.

[0010] The blocking member includes two arc-shaped fasteners, one end of the two fasteners is hinged to each other through a hinge rod, and the other end is provided with a connecting plate, and the connecting plate is provided with connecting holes. The connecting holes on the two connecting plates are arranged opposite to each other, and the two connecting plates are connected together by bolts.

[0026] A steel cage hoisting structure comprises a steel wire rope 1 and a hoisting ring 2; the hoisting ring 2 is provided with a plurality of through holes 3 for the steel wire rope 1 to pass through, and the plurality of through holes 3 are arranged on the hoisting ring 2 at equal intervals around the center of the hoisting ring 2. During hoisting, the hoisting ring 2 is placed directly above the steel cage, and the center of the hoisting ring 2 is aligned with the axis of the steel cage; one end of the steel wire rope 1 is a lifting end 4 for lifting by a crane, and the other end is provided with a through hole 3, and the end of the other end of the steel wire rope 1 is provided with a fixing structure 1 for fixing the steel cage, and the fixing structure 1 comprises a connecting piece 7, and the main reinforcement 5 of the steel cage is fixed by the connecting piece 7, so as to facilitate the subsequent lifting of the steel cage.

[0027] The lifting ring 2 is provided with a plurality of fixed structures 2 corresponding one to one with the fixed structures. The fixed structure 2 includes a connecting rod 6. One end of the connecting rod 6 is connected to the lifting ring 2, and the other end is provided with a connecting piece 2 8 for connecting the main reinforcement 5 of the steel cage. The connecting piece 2 8 is located directly below the connecting piece 1 7. The connecting piece 2 8 is also fixed to the main reinforcement 5 of the steel cage, and the corresponding connecting piece 1 7 and the connecting piece 2 8 are fixed on the same main reinforcement, and are arranged one above and one below. The setting of the connecting piece 2 8 plays a secondary fixing role, and the cooperation of the two makes the main reinforcement 5 and the lifting structure more stably fixed.

[0028] The steel cage hoisting structure, during hoisting, the hoisting ring 2 is placed just above the steel cage, and then the main reinforcement 5 of the steel cage is fixed by the fixing piece 1, and at the same time, the main reinforcement fixed by the plurality of fixing structures 2 and the corresponding fixing structure 1 is fixed, that is, the corresponding fixing structure 1 and the fixing structure 2 are fixed on the same main reinforcement, and the fixing structure 1 and the fixing structure 2 are arranged one above and one below to play a secondary reinforcement role, which is more stable than fixing by only one fixing structure, and the fixing structure 2 is connected to the hoisting ring 2, and the steel cage can be fixed by the hoisting ring and the steel wire rope, so that the steel cage can be quickly returned to the center during subsequent hoisting. After the steel cage is fixed to the hoisting structure, the lifting end 4 at one end of the steel wire rope 1 is connected to the crane hook, and the crane is lifted to lift the steel cage to the air, and after the steel cage is vertical, the steel cage is lowered to the pile hole to complete the hoisting of the steel cage; in this process, since the fixing structure 1 and the fixing structure 2 are simultaneously connected to the same main reinforcement 5 of the steel cage, the main reinforcement 5 of the steel cage is double fixed, which can effectively prevent the main reinforcement 5 from being separated from the hoisting structure.

[0029] In the utility model, both the connector 1 7 and the connector 2 8 include two arc-shaped fasteners 10, one ends of the two fasteners 10 are hinged to each other through a hinge rod 11. Specifically, one end of the fastener 10 is provided with a hole, and the hinge rod 11 passes through the holes of the two fasteners 10, and both ends of the hinge rod 11 are provided with blocking sections for preventing the fastener 10 from sliding out of the hinge rod 11, and the diameter of the blocking section is larger than the diameter of the hinge rod 11.

[0030] The other end of the fastener 10 is provided with a connecting plate 12, and the connecting plate 12 is provided with connecting holes. The connecting holes on the two connecting plates 12 are arranged opposite to each other, and the two connecting plates 12 are connected together by bolts 13. When the first and second connecting members 8 are fixed to the main reinforcement 5, the main reinforcement 5 is placed between the two fasteners 10, the two fasteners 10 are closed, and the bolts 13 are passed through the connecting holes of the two connecting plates 12 at the same time to fix the two connecting plates 12, and at the same time, the two fasteners 10 clamp the main reinforcement 5, so that the main reinforcement 5 is fixed. The structure is simple, the operation is convenient, and the assembly and disassembly are also convenient.

[0031] In the utility model, one end of the connecting rod 6 is hinged to the lifting ring, which is convenient for turning the direction when lifting the steel cage in the early stage, and smoothly lifting it from a horizontal position on the ground to a vertical position on the ground.

[0032] In the present invention, the plurality of fixed structures 1 surround the plurality of fixed structures 2, and the connecting member 1 7 and the connecting member 2 8 are located between the fixed structure 1 and the fixed structure 2, and are arranged one above the other.

[0033] In the utility model, the steel cage lifting structure also includes a blocking member 9. The structure of the blocking member 9 is the same as that of the connecting member 1 7 and the connecting member 2 8. During lifting, the blocking member 9 is fixed on the main reinforcement 5 and fixed above the connecting member 1 7. That is to say, the blocking member 9, the connecting member 1 7 and the connecting member 2 8 are arranged from top to bottom on the same main reinforcement 5. The blocking member 9 is neither connected to the wire rope 1 nor to the lifting ring 2, but is directly fixed to the main reinforcement 5. The connecting member 1 7 and the connecting member 2 8 will be subjected to the upward pulling force and the downward gravity of the steel cage, so the steel cage may slide down. However, the blocking member 9 is not subjected to the pulling force or the gravity, but only has the friction force with the main reinforcement 5. Compared with the connecting member 1 7 and the connecting member 2 8, it can prevent the main reinforcement 5 from sliding out of the connecting member 1 7, thereby further avoiding the separation of the steel cage from the lifting structure.

[0034] In the utility model, the fixing structure 1 includes a mounting block 14, the diameter of which is larger than the diameter of the through hole 1 3; the mounting block 14 is fixed to the end of the other end of the wire rope 1, and the mounting block 14 is fixed to the hinge rod 11, so that the connecting member 7 is fixed on the mounting block 14.

[0035] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
