Description

Technical Field

[0001] This utility model relates to the field of cantilever construction technology, specifically to a cantilever connection structure. Background Technology

[0002] Cantilevered steel structures are widely used in high-rise buildings, cultural and sports centers, transportation hubs, and other construction projects. These structures typically feature long overhangs and heavy self-weight loads. Traditional tower cranes and crawler cranes, limited by their working radius and lifting capacity curves, frequently face insufficient lifting torque when installing on the far-end cantilever sections. Statistics show that when the radius exceeds the rated value by 30%, the failure rate of conventional hoisting methods reaches as high as 72%, forcing construction companies to use costly specialized equipment or temporary structural reinforcement measures, resulting in poor economic efficiency.

[0003] When a small number of cantilevered steel components in a project are long and far from existing fixed hoisting equipment, or when the movement and adjustment of mobile hoisting equipment are limited, and the maximum lifting weight exceeds the maximum lifting distance of the hoisting equipment, but does not exceed the maximum lifting weight by more than 20%, temporarily replacing them with larger hoisting equipment is not economical and will prolong the construction period. Utility Model Content

[0004] In view of this, the present invention provides a cantilever component connection structure to solve the problem that when a small number of cantilever steel components in a project are long and far from existing fixed hoisting equipment, or when the movement and adjustment of mobile hoisting equipment are limited, and the maximum lifting weight exceeds the maximum lifting distance of the hoisting equipment, but does not exceed the maximum lifting weight by more than 20%, it is economical to temporarily replace the larger hoisting equipment and prolong the construction period.

[0005] This utility model provides a cantilever component connection structure, including:

[0006] Cantilevered component; the cantilevered component is configured as a split type;

[0007] A connecting structure is installed on the cantilever member to fix the split cantilever member into an integral structure.

[0008] Beneficial effects: The building foundation is constructed vertically, with embedded parts added within the foundation during construction. The cantilevered components are then horizontally installed on these embedded parts. The cantilevered components are designed as separate units, specifically divided into two sections. During installation, each section can be installed individually, and then the connecting structure is used to assemble the separate cantilevered components into a unified load-bearing structure. This structure is particularly useful when a small number of cantilevered steel components are long, far from existing fixed hoisting equipment, or when the movement and adjustment of mobile hoisting equipment are limited, exceeding the maximum lifting capacity of the equipment's maximum lifting distance. By segmenting the components to reduce the single lifting weight and rotating the installation to reduce torque, it adapts to lifting limitations, avoids the need for large hoisting equipment, and saves costs, making it especially suitable for space-constrained scenarios.

[0009] In one alternative embodiment, the cantilever member includes:

[0010] An anchorage section for the cantilevered component, wherein the anchorage section for the cantilevered component is horizontally installed on the building foundation;

[0011] A rotating section of a cantilever member, wherein the rotating section of the cantilever member is installed at the end of the anchoring section of the cantilever member away from the building base;

[0012] The connecting structure is installed between the anchoring section of the cantilever member and the rotating section of the cantilever member.

[0013] In one alternative embodiment, a first connecting surface is provided at the end of the cantilever member anchorage section away from the building base;

[0014] The rotating section of the cantilever component near the anchoring section of the cantilever component has a second connecting surface corresponding to the first connecting surface;

[0015] The first connecting surface has the same shape and size as the second connecting surface.

[0016] Beneficial effects: Facilitates subsequent welding work and ensures the stability of the connection between the anchorage section and the rotating section of the cantilever component.

[0017] In one alternative embodiment, the outer diameter of the cantilever member gradually decreases from the end closest to the building base to the end furthest from the building base.

[0018] Beneficial effects: From the end closest to the building base to the end furthest from the building base, the lower flange surface of the cantilever member gradually slopes upward. This ensures that the center of the cantilever member is close to the building base after installation, reducing the torque and guaranteeing the stability between the cantilever member and the building base.

[0019] In one optional embodiment, the connection structure includes: a first connector and a second connector, wherein the first connector is installed at the end of the upper flange of the cantilever member anchoring section away from the building base, and the second connector is installed at the end of the upper flange of the cantilever member rotating section near the cantilever member anchoring section, corresponding to the first connector.

[0020] The first connector is hinged to the second connector.

[0021] In one optional embodiment, the connection structure includes: a first connecting lug and a second connecting lug, wherein the first connecting lug is installed at the end of the lower flange of the cantilever member anchorage section away from the building base, and the second connecting lug is installed at the end of the lower flange of the cantilever member rotation section near the cantilever member anchorage section, corresponding to the first connecting lug.

[0022] Beneficial effects: Before assembling the cantilever component connection structure, the cantilever component is pre-assembled. The first connector is fixed to the side of the upper flange of the anchoring section of the cantilever component near the first connection surface, and the first connecting lug is fixed to the side of the anchoring section of the cantilever component near the first connection surface. The second connector is fixed to the side of the upper flange of the rotating section of the cantilever component near the second connection surface, and the second connecting lug is fixed to the side of the lower flange of the anchoring section of the cantilever component near the second connection surface. During assembly, the anchoring section of the cantilever component is hoisted first, and the end of the anchoring section away from the first connection surface is fixed to the building foundation, ensuring that the anchoring section of the cantilever component is horizontal. Next, the hook is installed on the lifting lug to lift the rotating section of the cantilever component, bringing the rotating section close to the anchoring section until the right end of the upper flange of the anchoring section is close to the end of the upper flange of the rotating section near the second connecting surface. The first and second connecting pieces are then close together, and the construction workers install them, hinged together. The hook is then slowly released, causing the rotating section of the cantilever component to rotate along the hinged position of the first and second connecting pieces. Finally, the first and second connecting surfaces come into contact, and a temporary connection is made by connecting the first and second connecting lugs. The connection gap between the first and second connecting surfaces is welded to fix the split cantilever component into an integral structure. The first connecting piece, the second connecting piece, the first connecting lug, and the second connecting lug are then removed, and the installation is complete. Through the aforementioned structure and installation steps, under restricted lifting conditions, the oversized components are segmented and their single lifting weight is reduced by rotating and connecting the cantilevered components. The torque is reduced through pin-shaft rotation, adapting to lifting limitations and improving the success rate of lifting. Furthermore, it eliminates the need for additional large lifting equipment, saving costs. Before installation, the pin-shaft connection nodes between the first and second connecting components, as well as temporary connection measures between the first and second connecting lugs, can be calculated and designed to ensure the safety of the construction project.

[0023] In one alternative embodiment, the cantilever member connection structure further includes a lug fixed to the upper flange of the rotating section of the cantilever member.

[0024] In one alternative implementation, the connecting structure is made of an alloy material.

[0025] Beneficial effects: Ensures the connection stability between the anchoring section and the rotating section of the cantilever component when the hook is released, preventing the rotating section from shifting due to breakage and affecting subsequent welding. Further avoids safety issues caused by the rotating section of the cantilever component falling off. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] Cantilevered steel structures are widely used in high-rise buildings, cultural and sports centers, transportation hubs, and other construction projects. These structures typically feature long overhangs and heavy self-weight loads. Traditional tower cranes and crawler cranes, limited by their working radius and lifting capacity curves, frequently face insufficient lifting torque when installing on the far-end cantilever sections. Statistics show that when the radius exceeds the rated value by 30%, the failure rate of conventional hoisting methods reaches as high as 72%, forcing construction companies to use costly specialized equipment or temporary structural reinforcement measures, resulting in poor economic efficiency.

[0038] When a small number of cantilevered steel components in a project are long and far from existing fixed hoisting equipment, or when the movement and adjustment of mobile hoisting equipment are limited, and the maximum lifting weight exceeds the maximum lifting distance of the hoisting equipment, but does not exceed the maximum lifting weight by more than 20%, temporarily replacing them with larger hoisting equipment is not economical and will prolong the construction period.

[0039] To solve the above technical problems, the following will be combined with... Figures 1 to 4 The following describes embodiments of the present invention.

[0040] According to an embodiment of the present invention, a cantilever component connection structure is provided, including a building base 1, a cantilever component 2, and a connection structure 3.

[0041] In this embodiment, as Figures 1 to 4 As shown, the building base 1 is constructed vertically. During construction, embedded parts are added within the building base 1, and the cantilevered component 2 is horizontally installed on the embedded parts. The cantilevered component 2 is designed as a split type, specifically divided into two sections. During installation, these sections can be installed one by one, and then the connecting structure 3 is used to assemble the split cantilevered component 2 into an integral load-bearing structure. With the above structure, when a small number of cantilevered steel components are long and far from existing fixed hoisting equipment, or when the movement and adjustment of mobile hoisting equipment are limited and exceed the maximum lifting weight of the maximum lifting distance of the hoisting equipment, the segmented design reduces the single lifting weight, and the rotational installation reduces the torque, adapting to lifting restrictions and avoiding the need for large hoisting equipment, thus saving costs. This is especially suitable for space-constrained scenarios.

[0042] Specifically, such as Figures 1 to 4 As shown, the cantilever component 2 includes a cantilever component anchoring section 21 and a cantilever component rotating section 22. The cantilever component rotating section 22 is a section that exceeds the load capacity. The cantilever component anchoring section 21 is fixed on the embedded part and is horizontally set. The cantilever component rotating section 22 is installed at the end of the cantilever component anchoring section 21 away from the building base 1 through the connecting structure 3. Specifically, the connecting structure 3 is installed at the connection position between the cantilever component anchoring section 21 and the cantilever component rotating section 22.

[0043] The connecting structure 3 includes: a first connector 31, a second connector 32, a first connecting lug 33, and a second connecting lug 34. Both the first connector 31 and the second connector 32 are pin-type lugs. The first connector 31 is installed at the end of the upper flange of the cantilever member anchorage section 21 that is furthest from the building base 1. Figure 4 The second connector 32 is installed at the right end of the upper surface of the cantilever member anchoring section 21, corresponding to the first connector 31, at the end of the upper flange of the cantilever member rotating section 22 near the cantilever member anchoring section 21; that is, at the left end of the upper surface of the cantilever member rotating section 22 in section 4. The first connecting lug 33 is installed at the end of the lower flange of the cantilever member anchoring section 21 away from the building base 1, that is... Figure 4 The second connecting lug 34 is installed at the right end of the lower surface of the anchoring section 21 of the cantilever component, and at the left end of the rotating section 22 of the cantilever component.

[0044] like Figures 1 to 4 As shown, the cantilever component connection structure also includes a lug 4, which is fixed to the upper flange of the rotating section 22 of the cantilever component, that is, the lug 4 is fixed to the upper surface of the rotating section 22 of the cantilever component, and the lug 4 is located to the right of the center of gravity of the rotating section 22 of the cantilever component.

[0045] The end of the cantilever component anchorage section 21 away from the building base 1 is provided with a first connecting surface; the end of the cantilever component rotation section 22 near the cantilever component anchorage section 21 is provided with a second connecting surface corresponding to the first connecting surface.

[0046] Before assembling the cantilever component connection structure, the cantilever component 2 is pre-assembled. The first connector 31 is fixed to the side of the upper flange of the cantilever component anchoring section 21 near the first connecting surface. The first connecting lug 33 is fixed to the side of the cantilever component anchoring section 21 near the first connecting surface. The second connector 32 is fixed to the side of the upper flange of the cantilever component rotating section 22 near the second connecting surface. The second connecting lug 34 is fixed to the side of the lower flange of the cantilever component anchoring section 21 near the second connecting surface.

[0047] During assembly, the cantilever component anchorage section 21 is hoisted first, and the end of the cantilever component anchorage section 21 away from the first connection surface is fixed to the building base 1 to ensure that the cantilever component anchorage section 21 is horizontal. Next, the hook is installed on the lifting lug 4 to lift the rotating section 22 of the cantilever component, so that the rotating section 22 of the cantilever component is close to the anchoring section 21 of the cantilever component, until the right end of the upper flange of the anchoring section 21 of the cantilever component is close to the end of the upper flange of the rotating section 22 of the cantilever component near the second connecting surface, and the first connecting piece 31 and the second connecting piece 32 are close together. The construction workers install the two, and the first connecting piece 31 and the second connecting piece 32 are hinged. Then the hook is slowly released, so that the rotating section 22 of the cantilever component rotates along the hinge position of the first connecting piece 31 and the second connecting piece 32. Finally, the first connecting surface and the second connecting surface are put together. The first connecting lug 33 and the second connecting lug 34 are connected and fixed temporarily. The connection gap area between the first connecting surface and the second connecting surface is welded to fix the split cantilever component 2 into an integral structure. The first connecting piece 31, the second connecting piece 32, the first connecting lug 33 and the second connecting lug 34 are cut off, and the installation is completed.

[0048] Through the above structure and installation steps, under restricted lifting conditions, the oversized components are segmented and the single lifting weight is reduced by rotating and connecting the cantilevered components 2. The torque is reduced by rotating the pin shaft, adapting to lifting restrictions, improving the lifting success rate, and eliminating the need for additional large lifting equipment, thus saving costs. Before installation, the pin shaft connection nodes between the first connecting component 31 and the second connecting component 32, as well as the temporary connection measures between the first connecting ear plate 33 and the second connecting ear plate 34, can be calculated and designed to ensure the safety of the construction project.

[0049] In one embodiment, such as Figures 1 to 4 As shown, the first connecting surface and the second connecting surface have the same shape and size. This facilitates subsequent welding work and ensures the stability of the connection between the anchoring section 21 and the rotating section 22 of the cantilever component.

[0050] In one embodiment, the outer diameter of the cantilever member 2 gradually decreases from the end closest to the building base 1 to the end furthest from the building base 1. Specifically, Figure 4 For example, from the end closest to the building base 1 to the end furthest from the building base 1, the lower flange surface of the cantilever member 2 gradually slopes upward. This makes the center of the cantilever member 2 close to the building base 1 after installation, reducing the torque and ensuring the stability between the cantilever member 2 and the building base 1.

[0051] In one embodiment, the connecting structure 3 is made of an alloy material to ensure the connection stability between the anchoring section 21 and the rotating section 22 of the cantilever component when the hook is released, preventing the rotating section 22 of the cantilever component from shifting due to breakage and affecting subsequent welding. This further avoids safety problems caused by the rotating section 22 of the cantilever component falling off.

[0052] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
