Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a super high-rise steel beam structure and its installation method. Background Technology

[0002] A super high-rise building is defined as a building with 40 or more floors or a building height exceeding 100 meters, regardless of whether it is a residential or public building.

[0003] For super high-rise buildings, the upper floors are significantly affected by air convection, necessitating solutions for earthquake resistance and thermal insulation. Current solutions involve constructing a glass curtain wall on the exterior and adding an additional layer on top, creating an insulation zone between the two glass curtain walls to reduce heat loss. However, the exterior glass curtain wall is typically constructed from individual steel structural components. Furthermore, the greater the height and the more frequent the hoisting operations, the higher the construction risks. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a super high-rise steel beam structure and its installation method, which can reduce the risks associated with the construction of super high-rise steel structures.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a super high-rise steel beam structure, comprising a main frame and a damping device, wherein the main frame comprises a main body, and the main body is a channel steel structure with sealed upper and lower ends;

[0008] A first side rod is rotatably connected to the middle side wall of the main body. A first connecting plate is fixedly connected to the end of the first side rod. A protruding strip is fixedly connected to the lower side wall of the main body. When the first side rod rotates downward, the first connecting plate just contacts and fixes with the protruding strip. The rotation path of the end of the first side rod is arc-shaped, while the first connecting plate and the protruding strip are in planar contact. When the first side rod rotates, causing the first connecting plate to press tightly against the protruding strip, the first side rod is limited and fixed to a certain extent by the pressure of the protruding strip. During the hoisting process, the first side rod can be prevented from shaking.

[0009] A second side rod is rotatably connected to the upper groove of the main body. A second connecting plate is fixedly connected to the end of the second side rod. A second stud is provided through the middle of the main body. A fourth hole is provided at the upper part of the main body. When the main frame is installed, the second side rod is in a horizontal state. The second stud is assembled into the fourth hole, which supports the second side rod. During the hoisting process, the second side rod is confined inside the main body, and the second stud prevents the second side rod from swinging out of the main body.

[0010] The first connecting plate and the second connecting plate are respectively connected to the damping device. The damping device includes a housing, and a hydraulic chamber is provided inside the housing. A piston is provided inside the hydraulic chamber. An overflow hole is provided on the piston. A connecting rod is fixedly connected to one end of the piston, and a third connecting plate is fixedly connected to the other end of the connecting rod. The damping device allows the connection between the main frames to have a distance of movement. After the hydraulic chamber is filled with liquid, the entire device has a buffering and shock absorption effect.

[0011] Preferably, the lower end of the main body is fixedly connected with a first bolt, and the upper end of the main body is provided with a first hole. The positions of the first bolt and the first hole correspond, that is, different main bodies can be assembled vertically.

[0012] Preferably, a first rotating shaft is provided through one end of the first side rod, and the first rotating shaft is rotatably engaged with the main body. A third hole is provided on the middle side wall of the main body. When the first side rod is horizontal, the first connecting plate and the third hole are in corresponding positions, that is, the first side rod is connected to the side of the main body.

[0013] Preferably, a second rotating shaft is provided through the end of the second side rod, and the second rotating shaft is rotatably engaged with the main body.

[0014] Preferably, the housing is provided with a flow channel, and the two ends of the flow channel are respectively connected to the two ends of the hydraulic chamber. The housing is provided with an adjusting bolt threaded in, and the lower end of the adjusting bolt extends into the flow channel. The overflow hole provided on the piston cannot be adjusted, but after adding the flow channel and the adjusting bolt, the damping of the damping device can be adjusted.

[0015] Preferably, a spring is provided inside the hydraulic chamber, with one end of the spring abutting against the piston and the other end abutting against the inner wall of the hydraulic chamber. A threaded hole is provided at one end of the housing, so that the connecting rod is in an extended state under the action of the spring.

[0016] Preferably, the first connecting plate, the second connecting plate, and the third connecting plate are all provided with through holes, and the through hole on the third connecting plate is the second hole.

[0017] An installation method for a super high-rise steel beam structure, based on the aforementioned super high-rise steel beam structure, includes the following steps:

[0018] Step 1: Hoist the main frame. Before hoisting, the first and second side rods are in a vertical state, and the first connecting plate at the end of the first side rod abuts against the protruding strip. The second side rod is constricted inside the main body, and the second stud stops the second side rod, which reduces the overall hoisting size and improves the convenience and safety of hoisting.

[0019] Step 2: After the main frame is moved to the designated position, the lower end of the main body is fixedly connected to the main frame or support component that has been fixed below. Then, rotate the first side rod to a horizontal state and install a damping device at the end. The other end of the damping device is fixedly connected to the main frame or support component that has been fixed on the side. Finally, remove the second stud, rotate the second side rod to a horizontal state, and install the second stud in the fourth hole. The damping device fixedly connected to the end of the second side rod is connected to the building body.

[0020] (III) Beneficial Effects

[0021] This invention provides a super high-rise steel beam structure and its installation method. It has the following beneficial effects:

[0022] 1. In this invention, when the main frame is hoisted, the first and second side rods are converged, which reduces the radial dimension of the main body, improves the convenience and safety of hoisting, and assembles multiple steel structures into one component, so that multiple hoistings can be completed in one hoisting, reducing the risk of multiple hoistings.

[0023] 2. The present invention includes a damping device, which facilitates the installation of the steel structure and provides shock absorption and buffering capabilities for the overall steel structure. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example:

[0031] like Figure 1-4 As shown, this embodiment of the invention provides a super high-rise steel beam structure, including a main frame and a damping device. In actual construction, the damping device can be selected according to the requirements. The main frame includes a main body 2, which is a channel steel structure with sealed upper and lower ends.

[0032] The middle side wall of the main body 2 is rotatably connected to a first side rod 4. In the figure, the first side rod 4 is in a straight state. In the architectural design, if there is a curved structure, the first side rod 4 can be changed to a curved structure. At the same time, the first side rod 4 is a T-shaped steel structure. The end of the first side rod 4 is fixedly connected to a first connecting plate 5 for connecting and fixing components. The lower side wall of the main body 2 is fixedly connected to a protruding strip 3. When the first side rod 4 rotates downward, the first connecting plate 5 just contacts and fixes with the protruding strip 3. A certain force is required when the first side rod 4 rotates. Since the trajectory of the first side rod 4 at the end is an arc, and the plane of the first connecting plate 5 and the upper end surface of the protruding strip 3 are in contact as a plane, when the first side rod 4 rotates, the first connecting plate 5 and the protruding strip 3 contact and squeeze, which can limit and fix the first side rod 4 to a certain extent. During the hoisting process, the first side rod 4 may sway.

[0033] The upper part of the main body 2 is rotatably connected to a second side rod 7. Similarly, the second side rod 7 adopts a T-shaped steel structure to improve its bending resistance. The end of the second side rod 7 is fixedly connected to a second connecting plate 6. A second stud 20 is installed through the middle of the main body 2. During the hoisting process, the second side rod 7 is stored inside the main body 2. At this time, the second stud 20 blocks the second side rod 7 to prevent it from rotating and being exposed during hoisting. A fourth hole 22 is provided on the upper part of the main body 2. When the main frame is installed, the second side rod 7 is in a horizontal state. The second stud 20 is assembled into the fourth hole 22, which supports the second side rod 7. The second bolt 20 can also serve as a support for the second side rod 7.

[0034] The first connecting plate 5 and the second connecting plate 6 are respectively connected to the damping device to provide shock absorption for the steel structure. The damping device includes a housing 11, inside which is a hydraulic chamber, and inside the hydraulic chamber is a piston 14. The piston 14 is provided with an overflow hole 13. When the piston 14 moves in the hydraulic chamber, its fluid passes through the overflow hole 13. Since the diameter of the overflow hole 13 is fixed, the movement of the piston 14 is restricted, thus demonstrating the damping effect. One end of the piston 14 is fixedly connected to a connecting rod 12, and the other end of the connecting rod 12 is fixedly connected to a third connecting plate 9 for connection.

[0035] The lower end of the main body 2 is fixedly connected with a first bolt 1, and the upper end of the main body 2 is provided with a first hole 8. The positions of the first bolt 1 and the first hole 8 are corresponding, that is, the two main bodies 2 can be connected in an upper and lower position. After the first bolt 1 is inserted into the first hole 8, it can be fixed with a nut.

[0036] One end of the first side rod 4 is provided with a first rotating shaft 21, which is rotatably engaged with the main body 2 to realize the rotational engagement of the first side rod 4. A third hole 19 is provided on the middle side wall of the main body 2. When the first side rod 4 is horizontal, the first connecting plate 5 and the third hole 19 are in corresponding positions. That is, when the two main frames are side by side, the two main frames are fixedly connected by the first connecting plate 5 and the third hole 19, and by bolts and nuts.

[0037] The end of the second side rod 7 is provided with a second rotating shaft 23, which is rotatably engaged with the main body 2 to realize the rotatable connection between the second side rod 7 and the main body 2.

[0038] The housing 11 is provided with a flow channel 18, and the two ends of the flow channel 18 are respectively connected to the two ends of the hydraulic chamber. By providing the flow channel 18, the liquid in the hydraulic chamber can not only pass through the overflow hole 13, but also through the flow channel 18. The housing 11 is provided with an adjusting bolt 17 threadedly, and the lower end of the adjusting bolt 17 extends into the flow channel 18. By adjusting the adjusting bolt 17, the cross-sectional area of ​​the flow channel 18 can be adjusted, thereby controlling the flow rate of the liquid passing through the flow channel 18, and further adjusting the damping magnitude of the damping device.

[0039] A spring 15 is installed inside the hydraulic chamber. One end of the spring 15 abuts against the piston 14, and the other end abuts against the inner wall of the hydraulic chamber. The spring 15 keeps the connecting rod 12 extending outward without external force, and can also compensate for errors in the installation and design between components. One end of the housing 11 is provided with a threaded hole 16, which can be fixedly connected with bolts, i.e., used for fixed connection.

[0040] The first connecting plate 5, the second connecting plate 6, and the third connecting plate 9 are all provided with through holes for passing through bolt components to achieve connection, and the through hole on the third connecting plate 9 is the second hole 10.

[0041] An installation method for a super high-rise steel beam structure, based on the aforementioned super high-rise steel beam structure, includes the following steps:

[0042] Step 1: Hoist the main frame. Before hoisting, the first side rod 4 and the second side rod 7 are in a vertical state, and the first connecting plate 5 at the end of the first side rod 4 abuts against the protrusion 3. The second side rod 7 is constricted inside the main body 2, and the second stud 20 stops the second side rod 7. By constricting the various components, hoisting can be convenient. At the same time, integrating multiple components into one assembly can reduce the number of hoisting operations.

[0043] Step 2: After the main frame is moved to the designated position, the lower end of the main body 2 is fixedly connected to the main frame or support that has been fixed below. Then, rotate the first side rod 4 to a horizontal state and install a damping device at the end. The other end of the damping device is fixedly connected to the main frame or support that has been fixed on the side. Finally, remove the second stud 20, rotate the second side rod 7 to a horizontal state, and install the second stud 20 in the fourth hole 22. The damping device fixedly connected to the end of the second side rod 7 is connected to the building body.

[0044] It should be noted that the aforementioned main frame is erected on the outside of the building for installing the glass curtain wall, and is attached to the outward side wall of the main body 2, specifically in... Figure 1 The back side shown has related connection structures, such as threaded connection holes on the side wall, which will not be described in detail here.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
