Description

Technical Field

[0001] The present invention relates to the technical field of civil engineering construction, and particularly relates to a column-integrated built-in tower crane climbing device and a climbing method. Background Art

[0002] During the construction of existing super high-rise office buildings, tower cranes are the most important hoisting and vertical transportation machinery. The externally hung self-climbing tower crane is a erection method in which the tower crane is attached to the external wall of the building structure through two supports and automatically rises on the building structure by using an additional support. The tower crane of this erection method is arranged outside the super high-rise building, has little impact on construction, can be retained and used for a relatively long time, and greatly facilitates the vertical transportation of mechanical and electrical installation and building decoration materials. However, when it climbs, it requires another tower crane or vertical transportation equipment such as a winch or an electric hoist to assist in turning the lowest support from bottom to top and a hydraulic power system to form a new support system. Construction workers need to work at high altitudes without protection outside the super high-rise building, which is relatively dangerous, and this severely restricts the popularization and use of the externally hung self-climbing tower crane.

[0003] With the proposal of the construction technical route of column-integration, the erection method of the tower crane has also been innovated accordingly. The two ends of its support can be respectively supported on the core tube and the mega-column, thus forming a new erection method. Construction workers can operate at the core tube end and the mega-column end respectively, and the safety has been improved to a certain extent. However, the construction method of turning and transporting the lowest support has not been fundamentally changed. The tower crane also requires an additional hydraulic power system for climbing.

[0004] Therefore, how to provide a support form that can realize self-climbing for the tower crane and a tower crane non-turning climbing method, so as to improve construction efficiency and reduce safety risks, is an urgent problem to be solved in the construction of existing super high-rise office buildings using self-climbing tower cranes.

Specific embodiment

[0019] In order to describe the technical solutions of the above invention in more detail, the following specific embodiments are listed to prove the technical effects; it should be emphasized that these embodiments are used to illustrate the present invention and not to limit the scope of the present invention.

[0020] The built-in tower crane climbing device provided by the present invention, as Figures 1 to 8d shown, includes a climbing steel beam laminated frame 50, a lattice guide rail 60 and a one-way rotation limit base 70, wherein: Both ends of the climbing steel beam laminated frame 50 are respectively erected on the core tube 10 and the giant column 20 on the left and right sides; a first steel platform 11 is arranged on the core tube 10, a second steel platform 21 is arranged on the giant column 20, and the first steel platform 11 and the second steel platform 21 are connected by a connecting bridge 30 to form an integral body to achieve synchronous construction and coordinated climbing; the built-in tower crane 40 is arranged between the core tube 10 and the giant column 20 and is an important vertical transportation equipment during the construction of super high-rise building structures, and is supported on the core tube 10 and the giant column 20 on both sides during the working and climbing states; There are two lattice guide rails 60, which are respectively arranged longitudinally on the opposite sides of the core tube 10 and the giant column 20; a plurality of positioning holes 61 arranged longitudinally are provided on the lattice guide rail 60; The climbing steel beam laminated frame 50 is arranged horizontally in multiple layers and is respectively arranged between the core tube 10 and the giant column 20 as the main support structure of the built-in tower crane 40; the built-in tower crane 40 can sequentially pass through the middle of the climbing steel beam laminated frame 50; the side surface of the climbing steel beam laminated frame 50 can be retractably inserted into the positioning hole 61 of the lattice guide rail 60; The one-way rotation limit base 70 is respectively installed on the core tube 10 and the mega-column 20. The one-way rotation limit base 70 includes a resting support 71. When the climbing steel beam laminated frame 50 applies an upward force to the resting support 71, it can drive the resting support 71 to turn and displace. When a downward force is applied to the resting support 71, the resting support 71 is used to support the climbing steel beam laminated frame 50, thereby realizing one-way limit. The one-way rotation limit base 70 is used for vertically resting and fixing the climbing steel beam laminated frame 50, and is a connection medium between the climbing steel beam laminated frame 50 and the core tube 10 / mega-column 20.

[0021] The present invention can realize that the built-in tower crane 40 is supported on the core tube 10 and the mega-column 20 to form a new erection method. On this basis, a new type of climbing steel beam laminated frame 50 is provided. The climbing steel beam laminated frame 50 can realize automatic climbing by means of the lattice guide rail 60 and realize self-overturning in cooperation with the one-way rotation limit base 70. The present invention can realize the non-turning climbing of the built-in tower crane 40, avoid the danger brought by the need for a vertical transportation device to assist in turning and supporting from bottom to top in the original system, and only use the power system of the climbing steel beam laminated frame 50 when the built-in tower crane 40 climbs, without an additional power system.

[0022] In some embodiments, please refer with emphasis to Figure 2 and Figure 3 , the climbing steel beam laminated frame 50 includes an upper channel steel beam 51, a lower channel steel beam 52, telescopic corbels 54 and a double-acting hydraulic cylinder 53. The double-acting hydraulic cylinder 53 is arranged between the upper channel steel beam 51 and the lower channel steel beam 52 and is used to adjust the distance between the upper channel steel beam 51 and the lower channel steel beam 52. By extending and retracting the double-acting hydraulic cylinder 53, the self-climbing of a single climbing steel beam laminated frame 50 is realized. The telescopic corbels 54 are installed at both ends of the upper channel steel beam 51 and the lower channel steel beam 52 and can be extended and retracted by their own power. When the telescopic corbels 54 extend, they can be inserted into the corresponding positioning holes 61 to realize the fixed connection between the climbing steel beam laminated frame 50 and the core tube 10 / mega-column 20. The climbing steel beam laminated frame 50 can cooperate with the one-way rotation limit base 70 and the lattice guide rail 60 to realize self-climbing.

[0023] In some embodiments, please refer with emphasis to Figure 1 , there are two upper and lower climbing steel beam laminated frames 50. The lower climbing steel beam laminated frame 50 is vertically connected to the built-in tower crane 40 and can drive the built-in tower crane 40 to climb upward together when the climbing steel beam laminated frame 50 climbs. The upper climbing steel beam laminated frame 50 is used for horizontally limiting the built-in tower crane 40.

[0024] In some embodiments, please continue to refer to Figure 1, the two climbing steel beam laminated frames 50 and the connecting bridge 30 are respectively connected to the built-in tower crane 40 through the cross-shaped connecting frames 55. In some embodiments, please refer to Figure 4 , each climbing steel beam laminated frame 50 includes two groups arranged in parallel, the cross-shaped connecting frame 55 is installed between the two climbing steel beam laminated frames 50, and the built-in tower crane 40 passes through the cross-shaped connecting frame 55, so that the climbing steel beam laminated frame 50 forms a hoop fixation on the standard section of the built-in tower crane 40 in the middle.

[0025] Correspondingly, there are three cross-shaped connecting frames 55 in total, namely the upper, middle and lower ones. The middle and lower ones are used to connect the standard section of the built-in tower crane 40 with the upper and lower climbing steel beam laminated frames 50, and the upper one is used to connect the standard section to the connecting bridge 30 when the built-in tower crane 40 is in the climbing state. The climbing steel beam laminated frame 50 is placed on the one-way rotation limit base 70 when the built-in tower crane 40 is in the working state, and is limited in the horizontal direction through the connection with the lattice guide rail 60.

[0026] In some embodiments, please refer to Figure 5 , the one-way rotation limit base 70 further includes an attachment wall support 72, a rotating shaft 73, a limit hole 74 and a limit shaft 75. The attachment wall support 72 is fixed to the building structure (core tube 10 or mega column 20) by connecting its fixing surface to the embedded part in the building structure at the end. The placing support 71 is hinged to the attachment wall support 72 through the rotating shaft 73. The rotation of the placing support 71 drives the limit shaft 75 to move in the limit hole 74, and the two boundaries of the limit hole 74 respectively correspond to the horizontal state and the vertical state of the placing support 71. In this embodiment, the one-way rotation limit bases 70 are arranged at intervals in the vertical direction, with two layers arranged and two layers left vacant, and so on in a cycle. The lattice guide rail 60 is connected to both sides of the one-way rotation limit base 70 (covering layer by layer), and the climbing steel beam laminated frame 50 can realize self-climbing with the help of the lattice guide rail 60, and realize overflipping and landing placement in combination with the special structure of the one-way rotation limit base 70.

[0027] In some embodiments, the placing support 71 changes from the vertical state to the horizontal state under the action of gravity, and after the climbing steel beam laminated frame 50 passes through the placing support 71, the placing support 71 is reset.

[0028] That is to say, under the combined action of the limit hole 74 and the limit shaft 75, the placing support 71 is fixed at a fixed position in the natural state, namely the horizontal state. At this time, the placing surface of the placing support 71 and the fixed surface of the wall-attached support 72 form a 90° angle. When an external object collides with the placing surface of the placing support 71 from bottom to top, the placing support 71 will rotate along the rotation shaft 73, thereby creating space for the upward movement of the external object. After the external object passes through, the placing support 71 reverses under the action of gravity and enters the horizontal state again.

[0029] The present invention also provides a method for climbing a column-integrated built-in tower crane, which is applied to the column-integrated built-in tower crane climbing device as described above, and includes the following steps: The initial state in this embodiment is as follows: the one-way rotation limit bases 70 are installed on the F(n - 5), F(n - 4), F(n), F(n + 1), F(n + 4), and F(n + 5) floors. A total of two upper and lower climbing steel beam laminated frames 50 are prepared for the built-in tower crane 40 and are respectively installed above the one-way rotation limit bases 70 on the F(n - 4) and F(n + 1) floors. The lower climbing steel beam laminated frame 50 located on the F(n - 4) floor provides initial vertical and horizontal limits for the built-in tower crane 40 through the cross-shaped connection frame 55. The upper climbing steel beam laminated frame 50 located on the F(n + 1) floor provides initial horizontal limit for the built-in tower crane 40 through the cross-shaped connection frame 55; in addition, the cross-shaped connection frame 55 located on the connecting bridge 30 also provides initial horizontal limit for the built-in tower crane 40, as Figure 1 shown.

[0030] Step 10: When the cross-shaped connection frames 55 of the upper climbing steel beam laminated frame 50 located on the F(n + 1) floor and the cross-shaped connection frame 55 located on the connecting bridge 30 provide initial horizontal limits for the built-in tower crane 40, the lower climbing steel beam laminated frame 50 climbs by itself, driving the built-in tower crane 40 to gradually climb upward along the lattice guide rail 60 until the lower climbing steel beam laminated frame 50 is vertically placed on the placing surface of the placing support 71 of the one-way rotation limit base 70, as Figure 6a shown.

[0031] Step 20: The lower climbing steel beam laminated frame 50 located on the F(n) floor provides vertical and horizontal limits for the built-in tower crane 40 through the cross-shaped connection frame 55, and the cross-shaped connection frame 55 located on the connecting bridge 30 provides initial horizontal limit for the built-in tower crane 40. The upper climbing steel beam laminated frame 50 climbs along the lattice guide rail 60 by itself until it is vertically placed on the placing surface of the placing support 71 of the one-way rotation limit base 70 located on the F(n + 5) floor, as Figure 6b shown.

[0032] After completing the above steps, the climbing steel beam laminated frame 50 straddles the one-way rotating limit base 70, driving the built-in tower crane 40 to complete a non-inverted climbing. At this time, the lower climbing steel beam laminated frame 50 on the F(n) floor provides initial vertical and horizontal limits for the built-in tower crane 40 through the cross-shaped connection frame 55, and the upper climbing steel beam laminated frame 50 on the F(n + 5) floor provides initial horizontal limits for the built-in tower crane 40 through the cross-shaped connection frame 55; the cross-shaped connection frame 55 on the connecting bridge 30 also provides initial horizontal limits for the built-in tower crane 40, as Figure 6c shown.

[0033] Step 30: The built-in tower crane 40 enters the normal vertical transportation working state, and uses the first steel platform 11 and the second steel platform 21 to complete the construction of the core tube 10 and the giant column 20. During this process, the one-way rotating limit base 70 and the lattice guide rail 60 on the F(n + 8) and F(n + 9) floors are installed for subsequent construction use. Specifically, under the construction technical route of the integration of the core tube 10 and the column, the core tube 10 and the giant column 20 are integrally constructed synchronously through the first steel platform 11 and the second steel platform 21. The first steel platform 11 and the second steel platform 21 can be integrally climbed through their own climbing power systems to complete the construction of the core tube 10 and the giant column 20 in sequence.

[0034] Repeat this process in cycles to alternately complete the non-inverted climbing of the built-in tower crane 40 and the construction of the core tube 10 and the giant column 20.

[0035] Using the above method can make up for the defect of the cumbersome existing technical process. Compared with the existing technology, it reduces the use of one support and the related processes for this support, saving construction costs; reducing the steps that relevant construction personnel need to operate, improving construction efficiency, and further enhancing the safety of non-inverted direct lifting.

[0036] In some embodiments, the self-climbing steps of the climbing steel beam laminated frame 50 include: The initial state of this embodiment is: the two ends of the lower Japanese steel beam 52 of the climbing steel beam laminated frame 50 are vertically placed on the placing surfaces of the placing supports 71 of the one-way rotating limit base 70, and the telescopic corbels 54 at the ends of the upper Japanese steel beam 51 and the lower Japanese steel beam 52 both extend into the positioning holes 61 of the lattice guide rail 60 and are fixedly connected thereto. The two-way hydraulic cylinder 53 is in the state where the piston rod is retracted at this time, as Figure 7a shown.

[0037] Step 11: Retract the telescopic corbels 54 at both ends of the upper Japanese steel beam 51 through the self-power of the telescopic corbels 54; drive the piston rod of the two-way hydraulic cylinder 53 to extend, driving the upper Japanese steel beam 51 to move upward until the telescopic corbels 54 are aligned with the target positioning holes 61, asFigure 7b as shown

[0038] Step 12: Extend the telescopic bracket 54 of the upper channel-shaped H-beam 51 by its own power of the telescopic bracket 54 into the positioning hole 61 of the lattice guide rail 60 to connect and fix it thereto, and transfer the vertical force to the upper channel-shaped H-beam 51, as Figure 7c as shown

[0039] Step 13: Retract the telescopic bracket 54 of the lower channel-shaped H-beam 52 by the own power of the telescopic bracket 54; drive the piston rod of the double-acting hydraulic cylinder 53 to retract, drive the lower channel-shaped H-beam 52 to move upward until the telescopic bracket 54 is aligned with the target positioning hole 61, as Figure 7d as shown

[0040] Step 14: Extend the telescopic bracket 54 of the lower channel-shaped H-beam 52 by its own power of the telescopic bracket 54 into the positioning hole 61 of the lattice guide rail 60 to connect and fix it thereto, and transfer the vertical force to the lower channel-shaped H-beam 52, as Figure 7e as shown

[0041] Step 15: Repeat Steps 11 to 14 to complete the self-climbing of the climbing steel beam laminated frame

[0042] In some embodiments, the steps of the non-inversion climbing, that is, the steps of the climbing steel beam laminated frame 50 climbing over the one-way rotation limit base 70, include: The initial state in this embodiment is: the two ends of the lower channel-shaped H-beam 52 of the climbing steel beam laminated frame 50 are vertically placed on the placing surfaces of the placing supports 71 in the one-way rotation limit base 70, the telescopic brackets 54 at the ends of the upper channel-shaped H-beam 51 and the lower channel-shaped H-beam 52 both extend into the positioning holes 61 of the lattice guide rail 60 to connect and fix it thereto, and the double-acting hydraulic cylinder 53 is in the state where the piston rod is retracted at this time, as Figure 7a as shown

[0043] Step 21: The climbing steel beam laminated frame 50 gradually climbs upward and leaves the lower one-way rotation limit base 70 and is located below the upper one-way rotation limit base 70; drive the piston rod of the double-acting hydraulic cylinder 53 to extend, drive the upper channel-shaped H-beam 51 after retracting the telescopic bracket 54 to move upward, and gradually touch the placing surface of the placing support 71, and the placing support 71 rotates around the rotation shaft 73 to create space for the upward movement of the upper channel-shaped H-beam 51, as Figure 8a as shown

[0044] Step 22: The upper channel-shaped steel beam 51 moves upward through the upper one-way rotation limiting base 70. The supporting seat 71 of the upper one-way rotation limiting base 70 reverses under the action of gravity and returns to the horizontal state. The telescopic bracket 54 of the upper channel-shaped steel beam 51 extends out by its own power into the positioning hole 61 of the lattice guide rail 60 to be connected and fixed thereto, as Figure 8b shown.

[0045] Step 23: The lower channel-shaped steel beam 52 is located below the upper one-way rotation limiting base 70. The piston rod of the bidirectional hydraulic cylinder 53 is retracted, driving the lower channel-shaped steel beam 52 after the telescopic bracket 54 is retracted to move upward and gradually touch the supporting surface of the supporting seat 71. The supporting seat 71 rotates around the rotation shaft 73 to create space for the upward movement of the lower channel-shaped steel beam 52, as Figure 8c shown.

[0046] Step 24: The lower channel-shaped steel beam 52 moves upward through the upper one-way rotation limiting base 70. The supporting seat 71 of the upper one-way rotation limiting base 70 reverses under the action of gravity and returns to the horizontal state. The telescopic bracket 54 of the lower channel-shaped steel beam 52 extends out by its own power into the positioning hole 61 of the lattice guide rail 60 to be connected and fixed thereto. At the same time, both ends of the lower channel-shaped steel beam 52 of the climbing steel beam laminated frame 50 are vertically placed on the supporting seats 71 of the one-way rotation limiting base 70 again, as Figure 8d shown.
