Description

Technical Field

[0001] This utility model relates to the field of support technology for external luffing tower cranes in the core tube of super high-rise buildings, and specifically to a support device for luffing tower cranes in super high-rise buildings. Background Technology

[0002] With the rapid advancement of industrialization, commercialization, and urbanization in modern society, land resources are becoming increasingly scarce. Under the pressure of limited land supply, the upward development of buildings has become an inevitable trend. Today, high-rise and super high-rise buildings are ubiquitous in major cities. Steel structures, due to their numerous significant advantages, are gradually becoming the preferred choice in the engineering field. These advantages include excellent earthquake and wind resistance, a smaller footprint, faster construction speed, and lower foundation construction costs.

[0003] Due to the significant weight of steel structures, ordinary tower cranes are insufficient to meet their lifting and hoisting requirements. Therefore, in actual construction, tower cranes with larger lifting capacities are required. The ultra-high-rise external luffing tower crane is a type of tower crane specifically designed for ultra-high-rise office buildings and other similar construction projects. The luffing tower crane is typically attached to the core tube structure of the tower, effectively transferring the load generated during operation to the overall structure of the building through a scientifically designed anchoring and support system. To ensure the overall stability of the luffing tower crane throughout the construction process and prevent safety accidents caused by swaying or overturning, support frames are usually installed on the tower crane during construction to further enhance its stability and safety.

[0004] However, traditional external luffing jib tower crane support frames for super high-rise buildings have some significant drawbacks in practical use. One major drawback is the cumbersome connection between the outer perimeter of the tower crane and the support frame, requiring substantial time and manpower for assembly. This complex connection method not only increases construction difficulty but also hinders the overall assembly of the support frame, severely reducing overall assembly efficiency and extending the construction period. Furthermore, when disassembling and maintaining the tower crane, this complex connection method also complicates the disassembly process, increasing maintenance costs and difficulty. These problems not only affect the construction progress and quality of super high-rise buildings but also pose a potential threat to construction safety. Utility Model Content

[0039] Please see Figures 1 to 10This embodiment provides a support device for a super high-rise luffing jib tower crane, including support embedded parts, two main support beams 1, two secondary support beams 2, two secondary beam tie rods 3, two horizontal support rods 4, and two inclined support rods 5. The support embedded parts are pre-embedded in the core tube 9, serving as the connection foundation between the entire support structure and the core tube 9. They provide reliable anchoring points for components such as the main support beams 1, horizontal support rods 4, and inclined support rods 5, ensuring that the support structure can be firmly attached to the core tube 9, effectively transferring the tower crane's load to the building structure, and guaranteeing the stability and safety of the support structure. The two main support beams 1 are arranged opposite each other, and one end of each main support beam 1 is detachably connected to the support embedded parts. The main support beams 1 are the main load-bearing components of the support structure, bearing the loads from the tower crane and other components, and transferring them to the support embedded parts and the building structure. The two secondary support beams 2 are arranged opposite each other and detachably connected to the top of the two main support beams 1, forming the upper frame of the support structure together with the main support beams 1, further enhancing the stability of the structure. Two secondary beam tie rods 3 are detachably connected to the two supporting secondary beams 2, facing each other. The tie rods 3 strengthen the connection between the supporting secondary beams 2, enhancing the overall rigidity of the upper frame of the support structure and preventing deformation or displacement of the supporting secondary beams 2 under stress, thus ensuring the stability of the support structure. Two horizontal support rods 4 are located on the left and right sides of the two supporting main beams 1, respectively. One end of each horizontal support rod 4 is detachably connected to the embedded support component, and the other end is detachably connected to the end of each supporting main beam 1 furthest from the embedded support component. The horizontal support rods 4 provide support and constraint to the supporting main beams 1 in the horizontal direction, limiting their horizontal displacement, improving the horizontal stability of the support structure, and ensuring the stability of the tower crane during operation. Two inclined support rods 5 are located below the two main support beams 1, and one end of each inclined support rod 5 is detachably connected to the embedded support component. The other end of each inclined support rod 5 is detachably connected to the end of each main support beam 1 away from the embedded support component. Through the inclined support of the inclined support rods 5, the vertical stability and anti-overturning ability of the support structure are enhanced, the vertical and horizontal loads from the tower crane are effectively distributed, and the bearing capacity and safety of the entire support structure are improved.

[0040] The secondary support beam 2 has a mounting section 201 at its top for connecting to the U-shaped bracket on the outside of the tower crane body. The mounting section 201 has several screw holes 2011 that mate with the U-shaped bracket, allowing the U-shaped bracket and the secondary support beam 2 to be connected by bolts. Compared to traditional, cumbersome connection methods, bolt connection is simpler and faster, improving assembly efficiency and facilitating subsequent disassembly and maintenance. Preferably, the U-shaped bracket and the secondary support beam 2 are connected by 10.9 grade high-strength bolts. 10.9 grade high-strength bolts have high tensile strength and yield strength, capable of withstanding large loads. Using 10.9 grade high-strength bolts ensures that the connection has sufficient strength and reliability under these loads, effectively preventing loosening or damage and guaranteeing the overall stability and safety of the tower crane support structure.

[0041] Please see Figure 10 In one embodiment, the supporting embedded parts include two main beam supporting embedded parts 6, two horizontal supporting embedded parts 7, and two inclined supporting embedded parts 8. The two main beam supporting embedded parts 6 and the two horizontal supporting embedded parts 7 are located on the same horizontal line, and the two main beam supporting embedded parts 6 are located between the two horizontal supporting embedded parts 7. The two inclined supporting embedded parts 8 are located directly below the two main beam supporting embedded parts 6. One end of the two main beam supporting embedded parts 6, the two horizontal supporting embedded parts 7, and the two inclined supporting embedded parts 8 are embedded in the core tube 9. The other end of the two main beam supporting embedded parts 6 is detachably connected to two supporting main beams 1, the other end of the two horizontal supporting embedded parts 7 is detachably connected to two horizontal support rods 4, and the other end of the two inclined supporting embedded parts 8 is detachably connected to two inclined support rods 5. The aforementioned embedded support components ensure a more uniform and rational distribution of forces in the horizontal and vertical directions, effectively enhancing the stability and anti-overturning capacity of the entire support structure. This allows it to better withstand various loads generated during the operation of the luffing jib tower crane, ensuring its safe operation.

[0042] In one embodiment, the main beam support embedded part 6, the horizontal support embedded part 7, and the inclined support embedded part 8 each include an embedded part at one end and a connecting part at the other end. The connecting parts of the main beam support embedded part 6, the horizontal support embedded part 7, and the inclined support embedded part 8 are connected to the main support beam 1, the horizontal support rod 4, and the inclined support rod 5 respectively via pins. Pin connections offer the advantages of strong connection and easy disassembly. During installation, construction personnel can quickly connect the support components to the embedded parts, improving assembly efficiency. During disassembly and maintenance, the components can be easily disassembled, facilitating inspection, repair, and replacement of components in the support structure, reducing maintenance costs and difficulty. Furthermore, the pin connection method allows for fine-tuning of the support components within a certain range to adapt to different construction conditions and installation requirements. This enables the support structure to better adapt to various errors and changes that may occur during the construction of super high-rise buildings, ensuring the installation accuracy and stability of the support structure, and further improving the reliability and safety of the entire luffing jib tower crane support structure.

[0043] Please see Figure 2 , Figure 7 Specifically, the connecting part of the main beam support embedded part 6 includes a first fixing plate 601 and two first lugs 602 vertically disposed on the first fixing plate 601, with the two first lugs 602 arranged parallel to each other. Each first lug 602 has a first pin hole 6021 that mates with a pin shaft, and the central axes of the two first pin holes 6021 coincide.

The thickness of the second lug 101 matches the spacing between the two first lugs 602, and the second lug 101 has a second pin hole 1011 that mates with a pin shaft. The aforementioned arrangement of the first lugs 602 and the second lugs 101 allows the pin shaft to be smoothly inserted and tightly connected to the main beam support embedded part 6 and the main beam 1, ensuring the stability of the connection, reducing shaking and displacement caused by excessive connection gaps, and improving the overall performance of the support structure.

[0044] In addition, several first reinforcing side ribs 603 are provided between the first fixed plate 601 and the two first lugs 602, and several second reinforcing side ribs 102 are provided on both sides of the second lug 101. The first reinforcing side ribs 603 and the second reinforcing side ribs 102 effectively enhance the strength and rigidity of the connection between the main beam support embedded part 6 and the main beam support 1, improve the reliability and stability of the entire connection, and ensure the safe operation of the luffing tower crane support structure.

[0045] Please see Figure 3 , Figure 6 , Figure 8Specifically, the connecting part of the horizontal support embedded part 7 includes a second fixing plate 701 and two third lugs 702 vertically arranged on the second fixing plate 701. The two third lugs 702 are arranged parallel to each other, and each third lug 702 has a third pin hole 7021 that mates with a pin shaft.

The two fourth lugs 103 are arranged parallel to each other, and each fourth lug 103 has a fourth pin hole 1031 that mates with a pin shaft. The central axes of the two fourth pin holes 1031 coincide with each other. Both ends of the horizontal support rod 4 are provided with fifth lugs 401. The thickness of the fifth lugs 401 matches the distance between the two third lugs 702 and the distance between the two fourth lugs 103. Each fifth lug 401 has a fifth pin hole 4011 that mates with a pin shaft. The aforementioned third ear piece 702, fourth ear piece 103, and fifth ear piece 401 enable the pin to be smoothly inserted and tightly connected to the horizontal support embedded part 7 and the horizontal support rod 4, and the horizontal support rod 4 and the support main beam 1, ensuring the stability of the connection, reducing the shaking and displacement caused by excessive connection gaps, and improving the overall performance of the support structure.

[0046] In addition, several third reinforcing side ribs 703 are provided between the second fixed plate 701 and the two third lugs 702, and several fourth reinforcing side ribs 104 are provided between the main support beam 1 and the two fourth lugs 103. The third reinforcing side ribs 703 and the fourth reinforcing side ribs 104 effectively enhance the strength and rigidity of the connection between the horizontal support rod 4, the horizontal support embedded part 7, and the main support beam 1, improve the reliability and stability of the entire connection, and ensure the safe operation of the luffing tower crane support structure.

[0047] Please see Figure 2 , Figure 7 , Figure 9Specifically, the connecting part of the inclined support embedded part 8 includes a third fixing plate 801 and two sixth ear pieces 802 vertically arranged on the third fixing plate 801. The two sixth ear pieces 802 are arranged parallel to each other, and each sixth ear piece 802 has a sixth pin hole 8021 that mates with a pin shaft. The central axes of the two sixth pin holes 8021 coincide with each other. Two seventh ear pieces 105 are provided at one end of the main beam 1 away from the main beam support embedded part 6. The two seventh ear pieces 105 are arranged parallel to each other, and each seventh ear piece 105 has a seventh pin hole 1051 that mates with a pin shaft. The central axes of the two seventh pin holes 1051 coincide with each other. Eighth ear pieces 501 are provided at both ends of the inclined support rod 5.

The aforementioned sixth ear piece 802, seventh ear piece 105, and eighth ear piece 501 allow the pin to be smoothly inserted and tightly connected to the inclined support embedded part 8 and the inclined support rod 5, and the inclined support rod 5 and the support main beam 1, ensuring the stability of the connection, reducing the shaking and displacement caused by excessive connection gaps, and improving the overall performance of the support structure.

[0048] In addition, several fifth reinforcing side ribs 803 are provided between the third fixed plate 801 and the two sixth ear pieces 802, and several sixth reinforcing side ribs 106 are provided between the main support beam 1 and the two seventh ear pieces 105. The fifth reinforcing side ribs 803 and the sixth reinforcing side ribs 106 effectively enhance the strength and rigidity of the connection between the inclined support embedded part 8 and the inclined support rod 5, improve the reliability and stability of the entire connection part, and ensure the safe operation of the luffing tower crane support structure.

[0049] In one embodiment, two secondary support beams 2 are bolted to the tops of two main support beams 1, and two secondary beam tie rods 3 are bolted between the two secondary support beams 2. Bolted connections are more convenient for installation and disassembly compared to other connection methods (such as welding). During construction, workers can use specialized tools to quickly tighten or loosen the bolts, improving construction efficiency and shortening the construction cycle. When maintenance, repair, or adjustment of the tower crane support structure is required, the secondary support beams 2 and tie rods 3 can be easily separated from other components, facilitating inspection, repair, and replacement of each component, which is beneficial for the long-term maintenance and management of the support structure.

[0050] Preferably, the secondary supporting beam 2 is connected to the main supporting beam 1 using 10.9 grade high-strength bolts, and the secondary beam tie rod 3 is connected to the secondary supporting beam 2 using 10.9 grade high-strength bolts. 10.9 grade high-strength bolts have high tensile strength and yield strength, enabling them to withstand large loads. Using 10.9 grade high-strength bolts ensures that these connections have sufficient strength and reliability under various loads, effectively preventing loosening or damage, and guaranteeing the stability and safety of the entire support structure.

[0051] Please see Figures 2 to 6 In one embodiment, lifting lugs 107 are provided at both ends of the top of the main support beam 1, the secondary support beam 2, the horizontal support rod 4, and the inclined support rod 5. During the installation of the support device for a high-rise luffing jib tower crane, the main support beam 1, the secondary support beam 2, the horizontal support rod 4, and the inclined support rod 5 are usually heavy and large in size. By providing lifting lugs 107 at both ends of the top, construction workers can directly connect the hooks of lifting equipment (such as tower cranes, cranes, etc.) to the lifting lugs 107 to accurately lift and move the components to the designated position, which greatly improves the efficiency and convenience of component installation and reduces the difficulty and risk of manual handling.
