Description

Technical Field

[0001] The present invention relates to the technical field of super high-rise core tube external hanging boom tower crane support, and in particular to a super high-rise core tube external hanging boom tower crane support structure and an installation method thereof. Background Art

[0002] In recent years, the industrialization, commercialization and urbanization of modern society have become increasingly intense. Due to limited land, buildings are forced to develop high, and high-rise and super-high-rise buildings are common in large cities. Steel structures have the advantages of earthquake resistance, wind resistance, small footprint, fast construction speed, and low foundation cost. They are gradually becoming the preferred structural type in engineering.

[0003] Since the steel structure itself is heavy, ordinary tower cranes cannot meet the lifting and hoisting requirements, so a boom tower crane with a larger lifting capacity is required. The super-high-rise external boom tower crane is a super-high-rise tower crane designed for super-high-rise office buildings. The boom tower crane is generally attached to the core tube of the tower, and the load of the tower crane is transferred to the structure of the building through a reasonable anchoring and support system. In order to ensure the overall stability of the boom tower crane during the construction process and avoid safety accidents caused by the shaking or overturning of the tower crane, a support frame is usually installed on the tower crane.

[0004] However, the traditional super-high-rise external boom tower crane support frame has some obvious defects in actual use. Among them, the connection method between the circular frame outside the tower crane body and the support frame is relatively cumbersome, and it takes a lot of time and manpower to assemble. This cumbersome connection method not only increases the difficulty of construction, but also brings obstacles to the overall assembly of the support frame, seriously reduces the overall assembly efficiency, and prolongs the construction period. In addition, when the tower crane needs to be disassembled and maintained, this complex connection method also brings inconvenience to the disassembly work, and increases the maintenance cost 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. Summary of the invention

[0047] See also Figures 1 to 10This embodiment provides a super-high-rise core tube external boom tower crane support structure, including support embedded parts, two support main beams 1, two support secondary beams 2, two secondary beam tie rods 3, two horizontal support rods 4 and two oblique support rods 5. The support embedded parts are embedded in the core tube 9 as the connection basis between the entire support structure and the core tube 9, providing reliable anchor points for components such as the support main beam 1, the horizontal support rod 4 and the oblique support rod 5, ensuring that the support structure can be firmly attached to the core tube 9, effectively transferring the load of the tower crane to the building structure, and ensuring the stability and safety of the support structure. The two support main beams 1 are arranged opposite to each other on the left and right, and one end of the two support main beams 1 is detachably connected to the support embedded parts respectively. The support main beam 1 is the main force-bearing component of the support structure, bearing the load from the tower crane and other components, and transferring it to the support embedded parts and the building structure. The two support secondary beams 2 are opposite to each other in front and back and are detachably connected to the top of the two support main beams 1, and together with the support main beams 1, they constitute the upper frame of the support structure, further enhancing the stability of the structure. The two secondary beam tie rods 3 are opposite to each other and are detachably connected between the two supporting secondary beams 2. The secondary beam tie rods 3 play a role in strengthening the connection between the supporting secondary beams 2, thereby enhancing the overall rigidity of the upper frame of the supporting structure, preventing the supporting secondary beams 2 from being deformed or displaced when subjected to force, and ensuring the stability of the supporting structure. The two horizontal support rods 4 are respectively located on the left and right sides of the two supporting main beams 1, and one end of the two horizontal support rods 4 is detachably connected to the supporting embedded parts, and the other end of the two horizontal support rods 4 is detachably connected to one end of the two supporting main beams 1 away from the supporting embedded parts. The horizontal support rods 4 play a role in supporting and restraining the supporting main beams 1 in the horizontal direction, limiting the displacement of the supporting main beams 1 in the horizontal direction, improving the horizontal stability of the supporting structure, and ensuring the stability of the tower crane during operation. The two oblique support rods 5 are respectively located below the two supporting main beams 1, and one end of the two oblique support rods 5 are detachably connected to the supporting embedded parts, and the other ends of the two oblique support rods 5 are detachably connected to one end of the two supporting main beams 1 away from the supporting embedded parts. Through the oblique supporting effect of the oblique support rods 5, the vertical stability and anti-overturning ability of the supporting structure are enhanced, the vertical load and horizontal load from the tower crane are effectively shared, and the bearing capacity and safety of the entire supporting structure are improved.

[0048] Among them, the top of the supporting secondary beam 2 is provided with a mounting portion 201 for connecting the circular bracket outside the tower crane body, and the mounting portion 201 is provided with a plurality of screw holes 2011 that match the circular bracket, so that the circular bracket and the supporting secondary beam 2 can be connected by bolts. Compared with the traditional cumbersome connection method, the bolt connection method is simpler and faster, improves the assembly efficiency, and is also convenient for subsequent disassembly and maintenance. Preferably, the circular bracket and the supporting secondary beam 2 are connected by 10.9-grade high-strength bolts. The 10.9-grade high-strength bolts have high tensile strength and yield strength and can withstand large loads. The use of 10.9-grade high-strength bolts can ensure that the connection parts have sufficient strength and reliability under these loads, effectively prevent the connection from loosening or damage, and ensure the overall stability and safety of the tower crane support structure.

[0049] See also Fig.10 In one embodiment, the support embedded parts include two main beam support embedded parts 6, two horizontal support embedded parts 7 and two oblique support embedded parts 8. The two main beam support embedded parts 6 and the two horizontal support embedded parts 7 are located on the same horizontal line, and the two main beam support embedded parts 6 are located between the two horizontal support embedded parts 7. The two oblique support embedded parts 8 are respectively located directly below the two main beam support embedded parts 6. One ends of the two main beam support embedded parts 6, the two horizontal support embedded parts 7 and the two oblique support embedded parts 8 are embedded in the core tube 9, and the other ends of the two main beam support embedded parts 6 are respectively detachably connected to the two supporting main beams 1, the other ends of the two horizontal support embedded parts 7 are respectively detachably connected to the two horizontal support rods 4, and the other ends of the two oblique support embedded parts 8 are respectively detachably connected to the two oblique support rods 5. The arrangement of the above-mentioned supporting embedded parts makes the force distribution of the supporting structure in the horizontal and vertical directions more uniform and reasonable, effectively enhances the stability and anti-overturning ability of the entire supporting structure, can better withstand the various loads generated by the boom tower crane during operation, and ensure the safe operation of the tower crane.

[0050] In one embodiment, the main beam support embedded parts 6, the horizontal support embedded parts 7 and the oblique support embedded parts 8 all include an embedded part arranged at one end and a connecting part arranged at the other end, and the connecting parts of the main beam support embedded parts 6, the horizontal support embedded parts 7 and the oblique support embedded parts 8 are respectively connected to the supporting main beam 1, the horizontal support rod 4 and the oblique support rod 5 through a pin. The pin connection has the characteristics of firm connection and convenient disassembly. During the installation process, the construction personnel can quickly connect the support components with the embedded parts, which improves the assembly efficiency; during disassembly and maintenance, the components can also be easily disassembled, which is convenient for inspection, maintenance and replacement of the support structure, reducing the maintenance cost and difficulty. In addition, the pin connection method allows the support components to be fine-tuned within a certain range to adapt to different construction conditions and installation requirements, so that the support structure can better adapt to various errors and changes that may occur during the construction of super-high-rise buildings, ensure the installation accuracy and stability of the support structure, and further improve the reliability and safety of the entire boom tower crane support structure.

[0051] See also Figure 2 , Figure 7 Specifically, the connection part of the main beam support embedded part 6 includes a first fixing plate 601 and two first ear pieces 602 vertically arranged on the first fixing plate 601, and the two first ear pieces 602 are arranged in parallel on the left and right. The first ear pieces 602 are respectively provided with first pin holes 6021 that match the pin shaft, and the central axes of the two first pin holes 6021 coincide with each other; a second ear piece 101 is provided at one end of the supporting main beam 1 close to the main beam support embedded part 6, and the thickness of the second ear piece 101 matches the spacing between the two first ear pieces 602, and a second pin hole 1011 that matches the pin shaft is provided on the second ear piece 101. The above-mentioned first ear piece 602 and second ear piece 101 enable the pin shaft to be smoothly inserted into and tightly connected to the main beam support embedded part 6 and the supporting main beam 1, thereby ensuring the stability of the connection, reducing the shaking and displacement caused by the excessive connection gap, and improving the overall performance of the supporting structure.

[0052] In addition, a number of first reinforcing side ribs 603 are arranged between the first fixed plate 601 and the two first ear pieces 602, and a number of second reinforcing side ribs 102 are arranged on both sides of the second ear piece 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 supporting embedded parts 6 and the supporting main beam 1, improve the reliability and stability of the entire connection part, and ensure the safe operation of the boom tower crane support structure.

[0053] See also Figure 3 , Figure 6 , Figure 8Specifically, the connecting portion of the horizontal support embedded part 7 includes a second fixed plate 701 and two third ear pieces 702 vertically arranged on the second fixed plate 701, the two third ear pieces 702 are arranged in parallel up and down, and the third ear pieces 702 are respectively provided with third pin holes 7021 that match the pin shaft, and the central axes of the two third pin holes 7021 coincide with each other; two fourth ear pieces 103 are arranged at one end of the supporting main beam 1 away from the main beam supporting embedded part 6, the two fourth ear pieces 103 are arranged in parallel up and down, and the fourth ear pieces 103 are respectively provided with fourth pin holes 1031 that match the pin shaft, and the central axes of the two fourth pin holes 1031 coincide with each other; fifth ear pieces 401 are arranged at both ends of the horizontal support rod 4, the thickness of the fifth ear piece 401 matches the spacing between the two third ear pieces 702 and the spacing between the two fourth ear pieces 103, and the fifth ear piece 401 is provided with a fifth pin hole 4011 that matches the pin shaft. The third ear piece 702, the fourth ear piece 103 and the fifth ear piece 401 arranged above enable the pin shaft to be smoothly inserted into and tightly connect the horizontal support embedded part 7 and the horizontal support rod 4, the horizontal support rod 4 and the supporting main beam 1, thereby ensuring the stability of the connection, reducing the shaking and displacement caused by excessive connection gap, and improving the overall performance of the supporting structure.

[0054] In addition, several third reinforcing side ribs 703 are arranged between the second fixed plate 701 and the two third ear pieces 702, and several fourth reinforcing side ribs 104 are arranged between the supporting main beam 1 and the two fourth ear pieces 103.

[0055] See also Figure 2 , Figure 7 , Fig. 9Specifically, the connecting portion of the oblique support embedded part 8 includes a third fixed plate 801 and two sixth ear pieces 802 vertically arranged on the third fixed plate 801, the two sixth ear pieces 802 are arranged parallel to each other, and the sixth ear pieces 802 are respectively provided with sixth pin holes 8021 that match the pin shaft, and the central axes of the two sixth pin holes 8021 coincide with each other; two seventh ear pieces 105 are arranged at one end of the supporting main beam 1 away from the main beam supporting embedded part 6, the two seventh ear pieces 105 are arranged parallel to each other, and the seventh ear pieces 105 are respectively provided with seventh pin holes 1051 that match the pin shaft, and the central axes of the two seventh pin holes 1051 coincide with each other; eight ear pieces 501 are arranged at both ends of the oblique support rod 5, the thickness of the eighth ear piece 501 matches the spacing between the two sixth ear pieces 802 and the spacing between the two seventh ear pieces 105, and the eighth ear piece 501 is provided with an eighth pin hole 5011 that matches the pin shaft. The above-mentioned arrangement of the sixth ear piece 802, the seventh ear piece 105 and the eighth ear piece 501 enables the pin shaft to be smoothly inserted into and tightly connect the oblique support embedded part 8 and the oblique support rod 5, the oblique support rod 5 and the supporting main beam 1, thereby ensuring the stability of the connection, reducing the shaking and displacement caused by excessive connection gap, and improving the overall performance of the supporting structure.

[0056] In addition, several fifth reinforcing side ribs 803 are arranged between the third fixed plate 801 and the two sixth ear pieces 802, and several sixth reinforcing side ribs 106 are arranged between the supporting main beam 1 and the two seventh ear pieces 105.

[0057] In one embodiment, two supporting secondary beams 2 are connected to the tops of two supporting main beams 1 by bolts, and two secondary beam tie rods 3 are connected between the two supporting secondary beams 2 by bolts. Bolt connection is more convenient in installation and disassembly than other connection methods (such as welding, etc.). During the construction process, construction personnel can use special tools to quickly tighten or loosen bolts, which improves construction efficiency and shortens the construction period. When the tower crane support structure needs to be maintained, overhauled or adjusted, the supporting secondary beams 2 and secondary beam tie rods 3 can also be separated from other components more conveniently, which is convenient for inspection, repair and replacement of each component, and is conducive to the long-term maintenance and management of the support structure.

[0058] Preferably, the supporting secondary beam 2 is connected to the supporting main beam 1 by 10.9-grade high-strength bolts, and the secondary beam tie rod 3 is connected to the supporting secondary beam 2 by 10.9-grade high-strength bolts. 10.9-grade high-strength bolts have high tensile strength and yield strength, and can withstand large loads. The use of 10.9-grade high-strength bolts can ensure that these connection parts have sufficient strength and reliability under various loads, effectively prevent the connection from loosening or damage, and ensure the stability and safety of the entire supporting structure.

[0059] See also Figures 2 to 7 In one embodiment, both ends of the top of the supporting main beam 1, the supporting secondary beam 2, the horizontal support rod 4 and the oblique support rod 5 are provided with lifting ears 107. During the installation process of the super-high-rise core tube external boom tower crane support structure, the supporting main beam 1, the supporting secondary beam 2, the horizontal support rod 4 and the oblique support rod 5 are usually heavy and large in size. By providing the lifting ears 107 at both ends of the top, the construction personnel can use the hook of the lifting equipment (such as tower crane, crane, etc.) to directly connect with the lifting ears 107, and 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.

[0060] See also Fig.11 In one embodiment, a method for installing a super high-rise core tube external boom tower crane support structure includes:

[0061] Step S1, construction preparation: measure and lay out, complete the installation of the main beam support embedded parts 6, horizontal support embedded parts 7, and inclined support embedded parts 8 on the core tube 9, and pour the outer wall concrete of the core tube 9, and prepare the tools, materials and related information required for installing the support device.

[0062] Among them, in the measurement and setting-out link, in addition to determining the position of the embedded parts, the verticality, flatness and other parameters of the core tube 9 should also be accurately measured to ensure that the basic conditions for the installation of the supporting structure meet the requirements. At the same time, for the installation of embedded parts, it is necessary to strictly follow the design drawings and specifications to ensure the positioning accuracy and anchoring depth of the embedded parts. Before pouring the concrete of the outer wall of the core tube 9, it is necessary to check the position and fixation of the embedded parts again to prevent the embedded parts from being displaced during the concrete pouring process. When preparing tools and tools, appropriate lifting equipment (such as tower cranes, car cranes, etc.), lifting rigging (such as wire ropes, shackles, etc.) and installation tools (such as wrenches, torque wrenches, etc.) should be equipped according to the weight and size of each component of the supporting structure. For materials, the supporting main beam 1, the supporting secondary beam 2 and other components should be inspected on site, and their quality certification documents, appearance quality, etc. should be checked to ensure that the materials meet the design requirements. In terms of relevant materials, in addition to construction drawings and technical briefing documents, construction record forms, quality inspection reports, etc. should also be prepared to record and trace the construction process.

[0063] Step S2, installing the supporting main beam 1: after the supporting main beam 1 is manufactured in the factory, it is transported as a whole to the construction site, and the supporting main beams 1 are installed one by one.

[0064] Among them, after the supporting main beam 1 is transported to the construction site, its appearance should be checked first to see if there is any deformation, damage, etc. If any problems are found, they need to be repaired or replaced in time. During installation, the supporting main beam 1 is lifted by lifting equipment so that it is aligned with the main beam support embedded part 6, and the supporting main beam 1 is connected to the embedded part through the pin. During the connection process, a torque wrench should be used to tighten the pin nut according to the torque value required by the design to ensure a firm connection. At the same time, it is necessary to check whether the installation angle and position of the supporting main beam 1 meet the design requirements. If there is any deviation, make adjustments in time.

[0065] Step S3, installing the horizontal support rods 4: after the horizontal support rods 4 are manufactured in the factory, they are transported as a whole to the construction site, and the horizontal support rods 4 are installed one by one.

[0066] Among them, after the horizontal support rod 4 is transported to the site, an appearance inspection is also carried out. During installation, one end of the horizontal support rod 4 is first connected to the horizontal support embedded part 7 through a pin, and then the position of the horizontal support rod 4 is adjusted so that the other end is aligned with the corresponding connection point on the support main beam 1, and then connected with a pin. In order to ensure the installation accuracy of the horizontal support rod 4, a measuring instrument (such as a total station, a level, etc.) can be used to measure and adjust its horizontality and verticality. During the installation process, attention should be paid to the tightness of the connection between the horizontal support rod 4 and the support main beam 1 and the embedded parts to avoid gaps.

[0067] Step S4, installing the oblique support rods 5: after the oblique support rods 5 are manufactured in the factory, they are transported as a whole to the construction site, and the oblique support rods 5 are installed one by one.

[0068] Among them, the installation of the oblique support rod 5 is similar to that of the horizontal support rod 4, but due to its inclination angle, the installation difficulty is relatively large. Before installation, the installation angle and position of the oblique support rod 5 must be determined according to the design drawings and marked. During installation, the oblique support rod 5 is lifted by a lifting device so that one end is connected to the oblique support embedded part 8 through a pin, and then the angle and position of the oblique support rod 5 are slowly adjusted so that the other end is aligned with and connected to the corresponding connection point on the supporting main beam 1. During the connection process, attention should be paid to the stress condition of the oblique support rod 5 to prevent it from being deformed due to uneven stress. After the installation is completed, the oblique support rod 5 can be subjected to a stress test to ensure that it can normally withstand the design load.

[0069] Step S5, installing the supporting secondary beams 2: after the supporting secondary beams 2 are manufactured in the factory, they are transported as a whole to the construction site, and the supporting secondary beams 2 are installed one by one.

[0070] Among them, after the supporting secondary beam 2 is transported to the site, its appearance and size are checked. During installation, the supporting secondary beam 2 is placed on the top of the supporting main beam 1, and the supporting secondary beam 2 is connected to the supporting main beam 1 through 10.9 grade high-strength bolts. When tightening the bolts, the operation must be carried out in accordance with the prescribed sequence and torque value to ensure that the connection is firm and the force is evenly applied. During the installation process, attention should be paid to the flatness and levelness of the supporting secondary beam 2, and tools such as a level can be used for measurement and adjustment.

[0071] Step S6, installing the secondary beam tie rods 3: after the secondary beam tie rods 3 are manufactured in the factory, they are transported as a whole to the construction site, and the secondary beam tie rods 3 are installed one by one.

[0072] Among them, the secondary beam tie rod 3 is inspected after being transported to the site. During installation, the secondary beam tie rod 3 is placed between the two supporting secondary beams 2, and the secondary beam tie rod 3 is connected to the supporting secondary beam 2 by 10.9 grade high-strength bolts. During the connection process, attention should be paid to the installation position and angle of the secondary beam tie rod 3 to ensure that it can effectively enhance the connection stiffness between the supporting secondary beams 2. After the installation is completed, the secondary beam tie rod 3 can be preloaded to ensure that it meets the design requirements.

[0073] The above-mentioned installation method of the super-high-rise core tube external boom tower crane support structure does not need to occupy the work site and does not need to set up the ground-mounted disc-type scaffolding, which reduces the safety risks during the erection process and eliminates the erection links, thereby improving work efficiency, greatly reducing construction costs, and shortening the construction period.
