Description

Technical Field

[0001] The utility model relates to a rigging and belongs to the field of rigging. Background Art

[0002] The application of prefabricated components in the construction industry is becoming more and more extensive, especially in prefabricated buildings, in which the main components are prefabricated components. The widespread application of prefabricated components has also given rise to the development of its hoisting industry.

[0003] At present, there is a lifting method that is to cast the corresponding embedded lifting sleeve into the prefabricated component at the same time when casting the prefabricated component, and then directly use the threaded lifting device to connect the component for lifting. This method is widely used, convenient for lifting, and highly safe. However, the traditional lifting device is a ring eye lifting device, which is generally used for vertical lifting, such as Figure 5 As shown, threaded steel and a threaded sleeve are first embedded in the concrete, wherein the threaded steel is threadedly connected to the threaded sleeve, and one end of the threaded steel extends out of the concrete. During lifting, the threaded cable head on the eye sling is threadedly fixed to the end of the threaded steel extending out of the concrete, and the lifting device is connected to the annular cable of the eye sling before lifting. Since the threaded cable head on the eye sling and the annular cable are pressed and fixed, the use of this eye sling will greatly reduce its breaking load when subjected to lateral force.

[0004] Therefore, there is a need for a rigging that can achieve multi-angle lifting and avoid reducing its breaking load when subjected to lateral forces. Summary of the Invention

[0005] The technical problem to be solved by the utility model is: in order to overcome the deficiencies of the prior art, a rigging is provided which can realize multi-angle lifting and avoid reducing the breaking load thereof when subjected to lateral force.

[0006] The technical solution adopted by the utility model to solve the above problems is: a rigging, including a sling, the sling is fixedly connected to a pressure block, the sling is squeezed by the pressure block to form an 8-shaped structure, the 8-shaped structure includes a first ring opening and a second ring opening, the pressure block is located between the first ring opening and the second ring opening, the first ring opening is provided with a ring, and the ring is fixedly connected to a threaded cable head.

[0007] Preferably, the diameter of the first ring opening is smaller than the diameter of the second ring opening.

[0008] Preferably, the pressing block is made of aluminum.

[0009] Compared with the prior art, the advantages of the present invention are:

[0010] The utility model provides a rigging. During the lifting process of the sling, the second ring opening and the sleeve ring can generate relative rotation, that is, the sleeve ring and the second ring opening are in an interlaced movable connection. During the lifting process at an angle, the sling will not bend or deform and be subjected to local stress, thereby ensuring the strength, thereby realizing multi-angle lifting and avoiding reducing the breaking load when subjected to lateral force.

[0018] A first ring opening 11 and a second ring opening 12 . DETAILED DESCRIPTION

[0019] like Figure 1-4 As shown, a rigging in this embodiment includes a sling 1, the sling 1 is fixedly connected to a pressure block 2, and the sling 1 is squeezed into an 8-shape by the pressure block 2. The 8-shaped structure includes a first ring opening 11 and a second ring opening 12. The pressure block 2 is located between the first ring opening 11 and the second ring opening 12. The diameter of the first ring opening 11 is smaller than that of the second ring opening 12. A ring 3 is sleeved on the first ring opening 11, and a threaded cable head 4 is fixedly connected to the ring 3. The material of the pressure block 2 is aluminum;

[0020] The rigging has the following states during use:

[0021] In the first state, after the threaded steel bar 6 and the threaded sleeve 7 are embedded from the upper surface of the concrete 5, the threaded cable head 4 is screwed to the end of the threaded steel bar 6 extending out of the concrete 5, and the lifting device is connected to the second ring opening 12. The second ring opening 12, the first ring opening 11 and the concrete 5 are arranged from top to bottom;

[0022] In the second state, after the threaded steel bar 6 and the threaded sleeve 7 are embedded from the side of the concrete 5, the threaded cable head 4 is screwed to the end of the threaded steel bar 6 extending out of the concrete 5, and the lifting device is connected to the second ring opening 12. The second ring opening 12 and the first ring opening 11 are distributed up and down, and the distribution direction of the first ring opening 11 and the second ring opening 12 is parallel to the side of the concrete 5;

[0023] Of course, in addition to the above two states, the rigging also has a third state, that is, when the surface of the threaded steel bar 6 and the threaded sleeve 7 embedded in the concrete 5 is an inclined surface, the second ring opening 12 and the first ring opening 11 are both distributed up and down;

[0024] In the above three states, during the lifting process, the second ring mouth 12 and the ring 3 of the sling 1 can generate relative rotation, that is, the ring 3 and the second ring mouth 12 are in an interlaced movable connection. During the angled lifting process, the sling 1 will not bend and deform and be subjected to local stress, thereby ensuring strength, thereby realizing multi-angle lifting and avoiding reducing its breaking load when subjected to lateral force. Among them, the breaking tensile force of the rigging is greater than 4 times the lifting load.
