Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a double-column climbing device and an attachment device based on a beam body. Background Art

[0002] In the construction of high-rise building concrete core tubes, the overall jacking platform usually relies on the vertical wall as a fulcrum due to its large weight. However, as the jacking platform develops towards lightweight, its weight is gradually reduced, and the force on the fulcrum is also reduced accordingly, making it possible to use the beam as a fulcrum. In addition, in high-rise office buildings with concrete structures, the outer circle of the structure usually lacks walls, and only the inner core tube has walls, which brings challenges to the arrangement of the jacking platform fulcrum, making it impossible to use conventional walls as fulcrum attachment sites. Therefore, in this type of building, the application of jacking platforms is almost non-existent.

[0003] It can be seen that the existing setting of the fulcrum structure of the jacking platform has limitations. It can be seen that there is an urgent need for a device that can arrange the position of the fulcrum of the jacking platform more flexibly, so as not to be restricted by the position of the wall, so that the jacking platform can be applied to a more common concrete structure system, thereby expanding the application range of the jacking platform.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0023] The present invention provides a double-column climbing device and attachment device based on a beam body, which adopts the main beam of the structure as a load-bearing member and innovatively proposes a double-column climbing method. The double columns are located on both sides of the beam body, and the load of the jacking platform is transferred to the main beam through the attachment mechanism. Compared with the traditional wall attachment device, the device can arrange the position of the fulcrum more flexibly, so it is not restricted by the position of the wall, so that the jacking platform can be applied to a more common concrete structure system, thereby expanding the application range of the jacking platform. The device has the characteristics of lightweight, easy operation, and high economy.

[0024] See also Figure 1-Figure 2 Each jacking platform 4 is divided into two climbing devices 1 by a transfer beam 5. The two climbing devices 1 are attached to the structural main beam 6 at intervals through an attachment device 2. The load is transferred to the two climbing devices 1 through the transfer beam 4, and then transferred to the structural main beam 6 through the attachment device 2.

[0025] Secondly, the attachment device 2 is also equipped with a driving device 3, and the climbing device 1 and the jacking platform 4 arranged on the climbing device 1 can be jacked up to the upper level through the jacking of the driving device 3 until the jacking platform completes the climbing of the entire floor height.

[0026] Furthermore, the climbing device in the present solution is a climbing track, which is symmetrically distributed, and the climbing track 1 is respectively and sequentially arranged through the openings 7 on both sides of the main beam 6.

[0027] The top of the climbing track 1 is connected to the jacking platform 4 through a conversion beam 5. The load of the jacking platform 4 can be transmitted to the two climbing tracks 1 through the conversion beam 5, and the two climbing tracks 1 then transmit the load force to the attachment device 2.

[0028] Climbing holes 11 are provided at regular intervals on each climbing rail 1 , and the climbing holes 11 are used to place the attachment device 2 and the driving device 3 .

[0029] The attachment devices 2 are arranged at intervals and connected with the floor slab, and are used to connect with the climbing device 1 so that the climbing device 1 is attached to the main beam 6 of the structure. Figure 3 The attachment device 2 includes a first steel beam 23 and a second steel beam 25 .

[0030] The first steel beam 23 is arranged laterally symmetrically, and a connecting component 21 is provided at the bottom thereof for fixed connection with the floor slab. The first steel beam 23 is in contact with the floor through the connecting component 21, and can transfer the load force to the structural main beam 6.

[0031] Furthermore, horizontal limit assemblies 24 are symmetrically arranged on the inner sides of the symmetrically arranged first steel beams 23 , and the climbing track 1 is located between the horizontal limit assemblies 24 . The climbing track 1 can be limited on both sides to limit the horizontal deviation of the climbing track 1 .

[0032] The second steel beams 25 are vertically symmetrically placed on the first steel beams 23, and a first latch 22 that can only rotate in one direction is set on one side of each second steel beam 25 relative to the climbing track 1, wherein the first latch 22 is used to extend into the climbing hole 11 of the climbing track 1, and the first latch 22 can only rotate upward but cannot rotate downward. Therefore, in the non-working state, since the first latch 22 cannot rotate downward, the climbing track 1 can be supported, so that the climbing track 1 is attached to the structural main beam 6.

[0033] Further, see Figure 3-Figure 4 A connecting piece 26 is also provided on the end surface of each second steel beam 25, and the connecting piece 26 is used to be hinged with the driving device 3. Through the cooperation of the driving device 3 and the attachment device 2, the climbing track 1 and the jacking platform 4 connected to the climbing track 1 can be climbed.

[0034] The driving device 3 in this solution is two sets of driving cylinders, which are symmetrically arranged and the bottoms are connected to the connecting members 26 on the attachment device 2 through pins.

[0035] See also Figure 4 A second latch 31 is symmetrically provided on one side of the driving end of the driving cylinder 3 relative to the climbing track. The second latch 31 is hook-shaped and can be engaged in the climbing hole 11 of the climbing track 1. When the driving cylinder 3 is extended, the second latch can form an upward supporting force on the climbing track 1, thereby driving the climbing track 1 to climb.

[0036] Furthermore, a track slot 32 is provided at the driving end of the driving cylinder 3 . The track slot 32 is arranged at the end and is engaged with the climbing track 1 to limit the positional relationship between the driving cylinder 3 and the climbing track 1 .

[0037] The climbing device 1 is connected to the jacking platform 4 through the conversion beam 5, and the load force of the jacking platform 4 can be transmitted to the climbing device 1. The climbing device 1 is cooperatively connected with the attachment device 2, and the attachment device 2 is connected to the floor through the connecting component 21, which can transmit the structural force of the jacking platform 4 to the structural main beam 6.

[0038] At the same time, one end of the driving device 3 is connected to the attachment device 2, and the other end is in contact with the climbing track 1 through the latch 31. Through the telescopic movement of the driving device 3 and the unidirectional rotating first latch 22 on the attachment device 2, the climbing track 1 can be continuously climbed upward.

[0039] Based on the above scheme, the double-column climbing device and the attachment device based on the beam body are constructed. The following example illustrates the working process of the device in a specific application. The specific working process is as follows:

[0040] When in working state, the attachment device 2 is connected to the floor slab of the structural main beam 6, and its first latch 22 is stuck in the climbing hole 11 of the climbing track 1. Since the first latch 22 is unidirectionally rotatable and cannot rotate downward, it supports the climbing track 1, so that the climbing track 1 is placed on the attachment device 2 and the structural main beam 6 through the first latch 22 of the attachment device 2.

[0041] When lifting, the second tongue 31 on the upper part of the driving cylinder 3 extends into the climbing hole 11 of the climbing track, and then the driving cylinder 3 extends, driving the second tongue 31 until it hits the upper surface of the climbing hole 11, and continues to extend the driving cylinder 3. The second tongue 31 provides an upward supporting force for the climbing track 1, pulling the climbing track 1 to climb upward. At the same time, during the climbing process, the climbing device 1 is disengaged from the first tongue 22 of the attachment device 2, and the first tongue 22 of the attachment device 2 can be rotated upward to prevent it from hindering the climbing of the column.

[0042] Then continue to extend the driving cylinder 3 until the first latch 22 of the attachment device 2 enters the next climbing hole, and then retract the cylinder until the first latch in the attachment device 2 abuts against the climbing hole at the climbing hole opening.

[0043] Then, the driving cylinder 3 is further retracted so that the second latching tongue 31 in the driving cylinder 3 enters the next climbing hole, thus completing a lifting stroke.

[0044] Repeat the above steps until the lifting platform completes the climb to the entire floor height.

[0045] The double-column climbing device and attachment device based on the beam body constituted by the above-mentioned scheme can arrange the position of the fulcrum more flexibly than the traditional wall attachment device, so it is not restricted by the position of the wall, so that the jacking platform can be applied to more common concrete structure systems, thereby expanding the application range of the jacking platform.

[0046] Secondly, the device as a whole adopts an assembled structure, the node structure is simple and clear, and it is convenient to disassemble and install, flexible and easy to operate.
