Description

Technical Field

[0001] This utility model relates to the field of tall steel structure building technology, specifically to a tower crane wall-mounted connection device for tall steel structure buildings. Background Technology

[0002] In the construction of tall steel structure buildings, tower cranes are the main vertical transportation machinery. As the building height continues to increase, the height of the tower cranes also increases accordingly. To ensure the stability of the tower cranes, they need to be connected to the steel structure through wall-mounted devices.

[0003] The building has a tube-in-tube all-steel frame structure. The main structure cannot be pre-embedded with wall-mounted connectors, resulting in no attachment points for the tower crane to be installed on the wall. Therefore, it is necessary to design a wall-mounted connection device to achieve a reliable connection with the main steel structure.

[0004] Traditional wall-mounted devices mainly consist of embedded parts and support beams. The length of the support beams is fixed, and the support beams of the corresponding length need to be made according to the distance between the tower crane and the building. This results in the support beams not being able to be reused, causing material waste. As the tower crane climbs, the overturning moment of the tower crane on the wall gradually increases, which makes it a critical issue whether the wall can withstand the force transmitted by the tower crane through the support frame.

[0005] Therefore, there is an urgent need for a new technology that can solve the problem of poor support. Utility Model Content

[0006] The purpose of this utility model is to provide a wall-mounted connection device for tower cranes in tall steel structure buildings to overcome the problems existing in the prior art. This utility model can achieve reliable attachment on a tube-in-tube all-steel structure, significantly improving the anti-overturning stability.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a wall-mounted connection device for tower cranes in tall steel structure buildings, comprising: An extended wall-mounted connector includes an arc-shaped wall-mounted connector and a U-shaped component. The U-shaped component is rotatably connected to the arc-shaped wall-mounted connector. The arc-shaped wall-mounted connector is used for welding to the steel column of the main structure, and the U-shaped component is used for welding to the end of the tower crane boom. Several right-angle shear keys are provided, and the arc-shaped wall-mounted connector is welded to the steel column through several right-angle shear keys to enhance the shear resistance and overall stability of the joint.

[0008] According to one embodiment of the present invention, the U-shaped component includes several U-shaped end plates and several U-shaped web plates. Every two U-shaped web plates are rotatably connected to the front and back sides of the arc-shaped wall-mounted connector for adjusting the tension angle. Each U-shaped end plate is connected to the bottom of every two U-shaped web plates.

[0009] According to one embodiment of the present invention, one end of the arc-shaped wall-mounted connector is an arc-shaped notch, and the other end of the arc-shaped wall-mounted connector is a wavy curved structure. The wavy curved structure includes a first outward protrusion, an inward concave portion, and a second outward protrusion connected in sequence, and mounting holes are opened on the first outward protrusion and the second outward protrusion.

[0010] According to one embodiment of the present invention, every two U-shaped web plates are rotatably connected to the front and back sides of the arc-shaped wall-mounted connector through a pin-fitting mounting hole.

[0011] According to one embodiment of the present invention, the curvature of the arc-shaped notch is adapted to the outer surface of the steel column.

[0012] According to one embodiment of the present invention, each U-shaped end plate is welded to the bottom of every two U-shaped web plates.

[0013] According to one embodiment of the present invention, the included angle between the arc-shaped wall-mounted connector and the web of the U-shaped component is 45°~60°.

[0014] According to one embodiment of the present invention, the arc-shaped wall-mounted connector is a prefabricated arc-shaped steel plate.

[0015] According to one embodiment of the present invention, one right-angled side of each right-angled shear key is welded to one side of the arc-shaped wall-mounted connector, and the other right-angled side of each right-angled shear key is welded to the side of the steel column.

[0016] According to one embodiment of the present invention, the right-angle shear key is a right-angle steel plate.

[0017] The above technical solution has the following advantages or beneficial effects: This utility model provides a wall-attachment connection device for tower cranes in tall steel structures. By welding the curved wall-attachment connector to the curved surface of the main steel column, reliable attachment is achieved on all-steel cylinder-in-cylinder structures where pre-embedded parts cannot be used, solving the problem of lack of attachment points for tall steel tower cranes. The U-shaped and curved components are rotatably connected by pins, allowing for stepless adjustment of the optimal tension angle of the jib from 45° to 60°, ensuring the optimal force transmission path and significantly improving anti-overturning stability. Furthermore, by welding right-angle shear keys at multiple key nodes, the shear strength and overall stiffness of the connection nodes are greatly enhanced, effectively suppressing the risk of overturning moment caused by the increased overturning moment due to tower crane ascent. This device uses a prefabricated dry connection, requiring only welding and pinning on-site. Construction is quick, quality is controllable, and it is unaffected by seasons. While ensuring structural safety, it significantly improves construction efficiency, saves materials and time, and provides a safe, economical, and efficient standardized solution for tower crane wall attachment in similar complex steel structure projects.

[0018] In some embodiments, by specifically defining the U-shaped component as including a U-shaped end plate and a U-shaped web, and employing a "double web clamping" structure in which every two U-shaped webs are rotatably connected to the front and back sides of the arc-shaped wall-mounted connector, the integrity and torsional stiffness of the hinged joint between the U-shaped component and the arc-shaped connector are greatly enhanced. The symmetrical layout can effectively resist the multidimensional loads transmitted from the jib, prevent the instability risk that may occur from a single-sided connection, and ensure the stability and reliability of the force transmission at the joint. The rotatable connection between the U-shaped web and the arc-shaped wall-mounted connector is the core of realizing the stepless adjustment of the jib angle. This structure allows the tensioning angle of the jib to be precisely and flexibly adjusted on the installation site according to the actual relative position of the tower crane and the steel column. Adjusting and locking the angle within the optimal range of 45° to 60° as required by industry standards ensures that the jib is always in the best axial stress state, efficiently transferring the tower crane load to the main structure. On the other hand, it also gives the device strong adaptability to working conditions, enabling it to cope with minor dimensional deviations that may occur during construction, improving fault tolerance and installation efficiency. Furthermore, the bottom connection of each U-shaped end plate with the bottom of a pair of U-shaped web plates together forms a stable U-shaped support structure, providing a wide, flat, and rigid operating interface for subsequent welding to the end of the tower crane jib, ensuring the quality and force transmission performance of the weld between the jib and the connecting device, and further enhancing the safety redundancy of the entire wall-mounted system.

[0019] In some embodiments, the arc-shaped notch at one end of the connector can achieve a high-precision curved surface fit with the outer surface of the main steel column, greatly increasing the welding contact area and ensuring the continuity and uniformity of load transfer from the connecting device to the main structure. This effectively reduces the risk of local stress concentration and improves the load-bearing capacity and safety margin of the node. The wavy curved structure at the other end (including a first outward protrusion, an inward concave portion, and a second outward protrusion) effectively disperses and absorbs the complex alternating stress from the auxiliary arm without significantly increasing the weight of the component. The mounting holes on the two outward protrusions provide precise positioning for the double-sided symmetrical hinge of the U-shaped web, ensuring the stability of the rotation center. This is the key structural foundation for achieving precise and reliable adjustment of the auxiliary arm angle.

[0020] In some embodiments, the U-shaped web and the arc-shaped wall-mounted connector are rotatably connected by pins, forming the core of the angle adjustment of the entire device. The pin connection provides a robust and precise hinged node that can withstand the tensile, compressive, and shear loads transmitted by the jib. At the same time, it allows construction personnel to flexibly and steplessly adjust the tension angle of the jib on the installation site, ensuring that it is precisely locked in the optimal mechanical force transmission range of 45° to 60°. This significantly optimizes the stress state of the wall-mounted rod, enhances the overall stability of the tower crane, and the dry connection method is convenient to construct and highly reliable. It does not require complex on-site processing, effectively improving installation efficiency and accuracy, and ensuring the repeatability and safety redundancy of the connection node.

[0021] In some embodiments, by precisely matching the curvature of the arc-shaped notch to the outer surface of the steel column, a tight fit with the maximum area between the connector and the main structure is achieved. This not only significantly increases the effective welding area and ensures the uniformity and continuity of load transfer, but also effectively avoids local stress concentration, greatly improves the stiffness and load-bearing reliability of the node connection, and fundamentally enhances the overall stability of the wall-mounted device.

[0022] In some embodiments, the defined welded structure brings key improvements to the structural integrity and mechanical performance of the device. By welding the end plate of the U-shaped component to the bottom of a pair of U-shaped component webs, a rigid U-shaped box structure is formed, which greatly enhances the bending and torsional stiffness of the U-shaped component itself, enabling it to effectively resist the complex alternating loads from the tower crane jib. This integrally formed structure provides a stable and reliable base for the butt welding of the jib ends, ensuring a smooth and complete path for force transmission from the jib to the connecting device.

[0023] In some embodiments, the included angle between the arc-shaped wall-mounted connector and the web of the U-shaped component is limited to 45°~60°, which determines the optimal angle range for force transmission of the jib. This ensures that the tower crane load can be transmitted to the main steel column through the jib in the most efficient form of axial force, greatly optimizing the force flow path and significantly reducing the bending moment and stress concentration at the connection node. This effectively improves the fatigue resistance, load-bearing capacity and long-term safety and reliability of the entire wall-mounted device.

[0024] In some embodiments, by defining the arc-shaped wall-mounted connector as a prefabricated arc-shaped steel plate, high-precision factory production of the component is achieved. Through prefabrication, it is possible to ensure that the arc curvature perfectly matches the outer surface of the steel column, ensuring welding quality and connection strength. At the same time, it significantly reduces on-site measurement, cutting and other operations, significantly improves construction efficiency and installation accuracy, and ensures the reliability and consistency of the node from the source.

[0025] In some embodiments, each right-angled shear key is welded to the arc-shaped wall-mounted connector and the side of the main steel column through its two mutually perpendicular right-angled sides, forming a stable triangular reinforced node. This transforms the shear force, which was originally mainly transmitted by the butt weld between the arc plate and the steel column, into compressive or tensile stress directly borne by the right-angled shear key, greatly enhancing the node's ability to resist the horizontal load and overturning moment of the tower crane. Its fully welded double right-angled side structure effectively disperses local stress, significantly improving the shear stiffness and overall stability of the connection device, providing a key guarantee for the safe operation of tall tower cranes under complex wind and dynamic loads.

[0026] In some embodiments, by defining the right-angle shear key as a right-angle steel plate, the standardized geometry and excellent mechanical properties of the right-angle steel plate provide efficient and reliable shear reinforcement for the node. Its two vertical sides provide an ideal welding plane for welding operations, ensuring high-quality full weld connections with the arc-shaped wall-mounted connectors and steel columns. This significantly enhances the shear bearing capacity and overall stiffness of the node, effectively suppresses relative displacement and deformation at the connection, and improves the safety and durability of the structure.

[0034] Example: This utility model proposes a wall-mounted connection device for tower cranes in tall steel structure buildings, which possesses sufficient strength, rigidity, stability, and rotation adjustment function points to meet tensioning angle requirements.

[0037] In some embodiments, each pair of U-shaped web plates 2 are rotatably connected to the front and back sides of the arc-shaped wall-mounted connector 4 via pins 3 and mounting holes.

[0038] In some embodiments, the mounting hole is adapted to the size of the pin 3.

[0039] In some embodiments, the mounting hole is a pin hole.

[0040] In some embodiments, the U-shaped web plate 2 is fixed to the arc-shaped wall-mounted connector 4 by a pin 3, and the assembled extended wall-mounted connector is hoisted to the predetermined position and welded to the main steel column 6, with the other end welded to the end of the attached arm.

[0041] In some embodiments, the curvature of the arc-shaped notch is adapted to the outer surface of the steel column 6.

[0042] In some embodiments, each U-shaped end plate 1 is welded to the bottom of every two U-shaped web plates 2.

[0045] In some embodiments, the arc-shaped wall-mounted connector 4 is a prefabricated arc-shaped steel plate.

[0046] In some embodiments, the arc-shaped wall-mounted connector 4 may be made of Q345 steel.

It meets the hoisting needs of large components on site, promotes construction progress, saves costs, and raises the quality and safety of the project to the predetermined goals.

Improper installation, such as substandard self-made support rods, lack of anti-torsional supports, or substitution of pins, shafts, or bolts for the attachment device, can weaken the tensile, torsional, and compressive strength of the attachment system, increasing safety hazards. This utility model can also solve the above-mentioned technical problems, facilitate installation, and easily achieve an angle of 45°~60° between the steel column 6 and the tower crane arm.

[0054] When using the aforementioned wall-mounted connection device for tower cranes in tall steel structures: Step 1: After designing the dimensions of the curved wall-mounted connector 4, the drawings are delivered to the steel component processing plant for prefabrication. After processing, the components are transported to the site, where the prefabricated curved wall-mounted connector 4 (i.e., the steel component) is inspected and accepted. After passing the inspection, it is used. The U-shaped plate is then fabricated. After the U-shaped plate is fabricated, the quality of all welds is checked to avoid quality problems. The curved wall-mounted connector 4 is connected to the web plate 2 of the U-shaped component using pins 3. The assembled extended wall-mounted connector is hoisted to the predetermined position and welded to the main steel column. The other end is welded to the end of the attached arm. To effectively reinforce the tower crane wall-mounted connection device, right-angle steel plates are used as shear keys, i.e., right-angle shear keys 5. Eight right-angle shear keys 5 are used to reinforce each node, four at the top and four at the bottom, with full welding at the contact points.

[0055] Step 2: After the tower crane wall-mounted connection device is installed, move the tower crane boom to the predetermined position and weld the tower crane boom to the end steel plate of the assembly.

It can make the connection between the connector and the web plate 2 of the U-shaped part tight, with good stress performance, fatigue resistance, and seismic performance, thus improving the practicality of the extended wall-mounted connector.

[0058] The right-angle shear key 5 in this utility model has a simple structure, is easy to process, and has good rigidity and stability. It adopts a double-sided welding method, with full welding at the contact parts, which effectively strengthens the tower crane wall-mounted connection device.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
