Abstract
Description
Technical Field
[0001] This utility model relates to the field of tower crane attachment embedded parts technology, specifically to a recyclable tower crane attachment embedded part with shock absorption function. Background Technology
[0002] Traditional tower crane attachments are typically embedded inside concrete structures, and once their location is determined, they cannot be changed or removed after construction. This not only wastes materials but also makes their placement inflexible. Furthermore, when the building reaches a certain height, multiple anchor points need to be added to connect with the tower crane. Traditional tower crane attachments lack seismic design, and in earthquake-prone areas, the tower crane is easily damaged by earthquakes without seismic resistance devices, making it unable to effectively withstand the impact of seismic forces.

The back plate is disposed on one side of the building beam body, and the lug plate is disposed on the other side of the building beam body. The tower crane attachment also includes a screw and a nut. The screw is sequentially connected to the back plate, the building beam body, and the lug plate. The nut is installed on the screw. An anti-seismic damping connection device is also provided on the lug plate. An anti-seismic damping elastic element is connected to the anti-seismic damping connection device. A connecting rod is provided on the tower crane attachment section, and the connecting rod is connected to the anti-seismic damping elastic element.

[0027] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 5 The recyclable tower crane attachment with shock absorption function shown includes: a back plate 1, a lug plate 2, and a tower crane attachment section 8. The back plate 1 is disposed on one side of the building beam body 9, and the lug plate 2 is disposed on the other side of the building beam body 9. The tower crane attachment also includes a screw rod 3 and a nut. The screw rod 3 is sequentially connected to the back plate 1, the building beam body 9, and the lug plate 2. The nut is installed on the screw rod 3. The lug plate 2 is also provided with a seismic damping connection device 12, and a seismic damping elastic element 6 is connected to the seismic damping connection device 12. The tower crane attachment section 8 is provided with a connecting rod 7, and the connecting rod 7 is connected to the seismic damping elastic element 6.
[0029] The aforementioned recyclable tower crane attachment with shock absorption function connects the seismic damping elastic element 6 and the tower crane attachment section 8 to the building beam body 9 via the back plate 1 and ear plate 2. During use, the screw 3 is used to sequentially cooperate with the back plate 1, the building beam body 9 and the ear plate 2 to achieve a detachable connection, which facilitates the later turnover of the tower crane attachment and enables reuse, reducing costs. At the same time, the seismic damping elastic element 6 can absorb vibrations, reduce the vibration during earthquakes, and thus reduce damage to the tower crane, giving the tower crane a certain impact resistance.
[0030] like Figure 1 As shown, in this embodiment, the tower crane attachment also includes a connector 5. The seismic damping connection device 12 has a seismic damping connection hole 13 corresponding to the connector 5. The diameter of the seismic damping connection hole 13 is 50mm. The connector 5 is connected to the seismic damping connection hole 13. The seismic damping connection device 12 is connected and installed with the seismic damping elastic element 6 through the setting of the connector 5. When vibration occurs, the seismic damping elastic element 6 absorbs the vibration, reduces the vibration during the earthquake, and thus reduces the damage to the tower crane.
[0031] like Figure 2 and Figure 5 As shown, in this embodiment, the back plate 1 has a back plate hole 11, and the ear plate 2 has an ear plate hole 10. Both the back plate hole 11 and the ear plate hole 10 are connected to the screw 3. The diameter of the back plate hole 11 is 26mm, the diameter of the ear plate hole 10 is 26mm, and the number of both the back plate hole 11 and the ear plate hole 10 is 6. By connecting the back plate hole 11 and the ear plate hole 10 to the screw 3, the seismic damping elastic element 6 and the tower crane attachment section 8 are connected to the building beam body 9. At the same time, the detachable connection form is adopted, which facilitates the later turnover of the tower crane attachment embedded parts, realizes reuse, and reduces costs.
[0032] like Figure 1 As shown, in this embodiment, the nut is a double-layer nut 4, which is connected to the screw 3. The structure of the double-layer nut 4 can effectively improve the connection strength between the back plate 1, the ear plate 2 and the building beam body 9, and ensure the safe use of the tower crane's attached embedded parts.
[0033] like Figure 1 As shown, in this embodiment, the length of the screw 3 is 500mm; the screw 3 is an M24 high-strength bolt, which is mainly made of round steel material and has full threads. The length and model of the screw 3 can be adjusted according to the usage requirements.
[0034] like Figure 2As shown, in this embodiment, the ear plate 2 has a length of 500mm, a width of 400mm, a thickness of 20mm, and is made of Q235 steel. The lateral spacing between the ear plate holes 10 is 161mm, the longitudinal spacing between the seismic damping connection devices 12 is 145mm, and the thickness of the seismic damping connection device 12 is 20mm. The length and width of the ear plate holes 10 at the four corners from the nearest edge of the ear plate 2 are both 50mm. The above dimensions can be adjusted according to actual construction needs.
[0035] like Figure 5 As shown, in this embodiment, the back plate 1 has a length of 500mm, a width of 400mm, a thickness of 20mm, and is made of Q235 steel. The lateral spacing between the back plate holes 11 is 161mm, and the distance between the back plate holes 11 at the four corners and the nearest edge of the back plate 1 is 50mm. The above dimensions can be adjusted according to actual construction needs.
[0036] like Figure 1 As shown in this embodiment, during the installation of the tower crane attachment embedded part, the installation of the embedded part requires that during the process of binding the reinforcing bars of the beam, the φ30 steel sleeve is fixed to the reinforcing bars of the building beam body 9 according to the positions of the back plate hole 11 and the ear plate hole 10. This is used to fix the back plate 1 and the ear plate 2 to the building beam body 9 through the screw rod 3. When pouring concrete at the position of the tower crane attachment embedded part, an early strength agent should be added so that the concrete component can reach the strength requirements for installing the embedded part in advance. After demolding, the back plate 1 and the ear plate 2 are fixed to the building beam body 9 by the screw rod 3. The two sides of the screw rod 3 are tightened and fixed with M24 double-layer nuts 4 and washers. Then, the seismic damping connection device 12 and the seismic damping elastic element 6 are connected and installed through the connector 5. The seismic damping elastic element 6 is connected to the connecting rod 7. After the installation is completed, the crane can be installed on the tower crane attachment section 8.
[0037] Using this recyclable tower crane attachment with shock absorption function, taking the construction of a 33-story residential building as an example, the material usage is as follows: back plate 1: 376.8Kg, ear plate 2: 678.24Kg, screw rod 3: 127.8Kg, totaling 1055.04Kg for the 20mm thick steel plate and 127.8Kg for the φ24 round steel. Using traditional pre-embedded crane attachments, the material usage is: 1356.48Kg for the 20mm thick steel plate. The φ24 round steel weighs 172.8Kg. Based on the above calculations and comparisons, it is evident that using recyclable tower crane attachments with shock absorption function saves 301.4Kg of 20mm thick steel plate and 45Kg of round steel compared to traditional crane attachments in this project, resulting in a total material cost saving of 1384.68 yuan. Furthermore, this project involves a 33-story residential building; if these recyclable tower crane attachments with shock absorption function are used in multiple projects and buildings, costs can be further reduced.
[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
