Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically a special lifting bolt for prefabricated walls. Background Technology

[0002] At present, prefabricated walls are quite common on construction sites. The existing installation methods mostly use tower cranes as transportation tools, and then use ropes and lifting points of the prefabricated walls for transportation and installation. Often, the safety of hoisting is ignored. Some lifting points of prefabricated walls cannot guarantee the safety of lifting. Existing lifting points lead to reduced hoisting efficiency and make it difficult to guarantee effective positioning, increasing safety hazards. Utility Model Content

[0003] The purpose of this utility model is to provide a special lifting bolt for prefabricated walls. By combining the bolt body with the lifting ring, it is convenient to install the lifting ring on the prefabricated wall. At the same time, the lifting plate is closely fitted with the prefabricated wall, increasing the friction between the bolt body and the prefabricated wall, ensuring the stability between the bolt body and the prefabricated wall, thereby ensuring the safety of the prefabricated wall hoisting and solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a special prefabricated wall hanger bolt, comprising:

[0005] Bolt body;

[0006] The bolt body includes a bolt body, which is mounted on a lifting ring. A lifting device partition is welded to the outside of the lifting ring, and the lifting device partition is located outside the bolt body.

[0007] The bolt body includes a bolt post and a bolt head. The bolt head and one end of the bolt post are integrally formed. The lifting ring has a first through hole and a second through hole at the upper and lower positions.

[0008] Preferably, the lifting ring has a through hole, which communicates with the second through hole and is located on the side of the lifting ring away from the first through hole. The bolt post is located in the through hole, and the bolt head is located in the second through hole.

[0009] Preferably, the lifting ring is welded to the top of the lifting device partition, the lifting device partition has a circular hole at its center, the bolt post is located in the circular hole, and the bolt head is located in the second through hole.

[0010] Preferably, a lifting pad is fitted on the outer side of the bolt post, and the outer diameter of the lifting pad is smaller than the size of the bolt head.

[0011] Preferably, the bolt body is installed on the precast wall, the top of the precast wall has a pre-embedded hanging nail hole, the bolt column is threaded to the hanging nail hole, and the side of the lifting device partition away from the lifting ring is attached to the precast wall.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model connects the bolt body to the precast wall by threading the bolt post with the pre-embedded lifting nail hole. The lifting ring and the first through hole facilitate the connection of the bolt body with a lifting rope. The subsequent stable connection between the lifting plate and the lifting ring ensures that the bolt body increases friction after contacting the precast wall, preventing the bolt body from rotating and falling off the precast wall. This increases the stability between the bolt body and the precast wall, providing a safety guarantee for the assembly of the precast wall.

[0014] This utility model allows the bolt body to be rotated without changing the position of the lifting ring, so that the lifting device partition can be attached to the precast wall. This avoids the bolt body being fixedly connected to the lifting ring and the lifting device partition, which would cause the lifting device partition to slide and rub against the surface of the precast wall when the bolt body is rotated, resulting in wear on the lifting device partition and shortening the service life of the bolt body.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] like Figures 1-2 As shown, a special hanging bolt for prefabricated walls includes:

[0023] Bolt body;

[0024] The bolt body includes a bolt body 1, which is mounted on a lifting eye 2. A lifting device partition 3 is welded to the outside of the lifting eye 2, and the lifting device partition 3 is located on the outside of the bolt body 1.

[0025] The bolt body 1 includes a bolt post 101 and a bolt head 102. The bolt head 102 is integrally formed with one end of the bolt post 101. The lifting ring 2 has a first through hole 4 and a second through hole 5 at the upper and lower positions.

[0026] The lifting ring 2 has a through hole 6, which is connected to the second through hole 5 and is located on the side of the lifting ring 2 away from the first through hole 4. The bolt post 101 is located in the through hole 6, and the bolt head 102 is located in the second through hole 5.

[0027] By passing the bolt post 101 through the through hole on the lifting ring 2, the tension on the bolt body 1 is directly applied to the lifting ring 2. The lifting ring 2 is used to connect the bolt body 1 to the rope. The lifting plate 3 only serves to limit the bolt body 1 and prevent the bolt body 1 from rotating, which would cause the bolt post 101 to separate from the lifting pin hole 10.

[0028] Among them, such as Figure 2 As shown:

[0029] A lifting pad 8 is fitted on the outer side of the bolt post 101. The outer diameter of the lifting pad 8 is smaller than the size of the bolt head 102. By setting the lifting pad 8, the friction between the bolt post 101 and the lifting pin hole 10 is increased, the stability of the bolt body is improved, and the bolt post 101 is prevented from rotating.

[0030] Furthermore, such as Figure 5 As shown:

[0031] The bolt body is installed on the precast wall 9. The top of the precast wall 9 has a pre-embedded hanging nail hole 10. The bolt column 101 is threadedly connected to the hanging nail hole 10. The side of the lifting plate 3 away from the lifting ring 2 is attached to the precast wall 9. The pre-embedded hanging nail hole 10 on the precast wall 9 does not affect the integrity of the appearance of the precast wall 9, nor does it affect the installation of the precast wall 9. Example 2

[0032] like Figure 3-4 As shown, a special hanging bolt for prefabricated walls includes:

[0033] Bolt body;

[0034] The bolt body includes a bolt body 1, which includes a bolt post 101 and a bolt head 102. The bolt head 102 is integrally formed with one end of the bolt post 101. A lifting ring 2 is provided on the outer side of the bolt body 1. The lifting ring 2 has a first through hole 4 and a second through hole 5 at the upper and lower positions. The lifting ring 2 is welded to the top of the lifting device partition 3. A circular hole 7 is provided at the center of the lifting device partition 3. The bolt post 101 is located in the circular hole 7, and the bolt head 102 is located in the second through hole 5.

[0035] By connecting the bolt body 1 to the lifting device partition 3, and then welding the lifting ring 2 to the lifting device partition 3, the bolt body 1 and the lifting ring 2 are indirectly connected. The lifting device partition 3 disperses the traction force on the bolt body 1, preventing the lifting ring 2 from being subjected to excessive tension and deforming.

[0036] Preferred, such as Figure 3-4 As shown:

[0037] A lifting pad 8 is fitted on the outer side of the bolt column 101. The outer diameter of the lifting pad 8 is smaller than the size of the bolt head 102.

[0038] It is worth noting that, such as Figure 5 As shown:

[0039] The bolt body is installed on the precast wall 9. The top of the precast wall 9 has a pre-embedded hanging nail hole 10. The bolt column 101 is threadedly connected to the hanging nail hole 10. The side of the lifting device partition 3 away from the lifting ring 2 is attached to the precast wall 9.

[0040] In practical use, the bolt body is threaded into the pre-embedded ceiling hole on the precast wall 9 through the bolt post 101. The bolt body 1 is rotated so that the lifting plate 3 fits against the outside of the precast wall 9. Then, the bolt body is connected to the first through hole 4 on the lifting ring 2 through the rope on the tower crane, and the precast wall 9 is lifted and installed by the bolt body.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
