Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a beam-based sleeve-column climbing device and a climbing method. 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] Patent application number: 202411470983.5 proposes a double-column climbing device and an attachment device based on a beam body to solve the problem of setting the fulcrum on the beam body. However, this method has the disadvantage of requiring manual disassembly and reversal of the cylinder after each jacking, which is time-consuming and labor-intensive.

[0004] In order to solve this problem, the present invention proposes a sleeve column climbing device based on a beam body. The climbing device is divided into an outer sleeve column and an inner sleeve column. The cylinder device is connected to the bottom of the outer sleeve column and climbs with the outer sleeve column. Compared with the device of patent 202411470983.5, the device can realize the oil cylinder without reverse transportation, and there is no need to install and disassemble the oil cylinder and supporting oil pipes and other facilities back and forth, reducing the time and economic cost of manual installation and disassembly and reverse transportation of the oil cylinder on site. The device has the characteristics of lightweight, easy operation, and high economy. Summary of the invention

[0005] In view of the above technical problems existing in the existing climbing devices, the purpose of the present invention is to provide a sleeve column type climbing device and a climbing method based on a beam body. The telescopic assembly device of this scheme is connected to the bottom of the outer sleeve column and climbs with the outer sleeve column, which can realize the oil cylinder without reverse transportation, and there is no need to install and disassemble the oil cylinder and supporting oil pipes and other facilities back and forth, reducing the time and economic cost of manual installation and disassembly and reverse transportation of the oil cylinder on site. The device has the characteristics of lightweight, easy operation, high economy, etc.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a beam-based sleeve column climbing device, comprising two outer sleeve columns, a plurality of attachment devices,

[0007] The two outer sleeve columns are symmetrically arranged and sequentially pass through the openings on both sides of the main beam. The tops of the two outer sleeve columns are connected to the jacking platform by arranging a conversion beam, and the load of the jacking platform is transferred to the outer sleeve columns through the conversion beam.

[0008] The attachment device is arranged at intervals and connected with the floor slab, and is characterized in that an inner sleeve column that can slide up and down is inserted into the inner sleeve column, and climbing blocks are arranged at intervals on the inner sleeve column, and a tongue that can only rotate in one direction is arranged on the surface of the outer sleeve column and the end surface of the inner sleeve column away from the outer sleeve column on the side opposite to the attachment device for being placed on the attachment device, and the outer sleeve column and the inner sleeve column are pressed on the attachment device through the tongue to transfer the load to the structural beam.

[0009] The bottom of the outer sleeve column is connected with a first reversing claw assembly, the first reversing claw assembly is connected with a telescopic assembly, the telescopic assembly is connected with a second reversing claw assembly, the first reversing claw assembly and the second reversing claw assembly are engaged with a climbing block on the inner sleeve column;

[0010] The first reversing claw assembly and the second reversing claw assembly can form a first position and a second position by rotating. In the first position, the first reversing claw assembly and the second reversing claw assembly can only move upward in one direction relative to the climbing block. In the second position, the first reversing claw assembly and the second reversing claw assembly can only move downward in one direction relative to the climbing block.

[0011] Furthermore, the outer sleeve column is a rectangular tube outer sleeve column, and the inner sleeve column is inserted into the outer sleeve column and is an H-shaped steel inner sleeve column.

[0012] Furthermore, the end of the inner sleeve column away from the outer sleeve column is connected to a base, and a one-way flippable latch is connected to the base.

[0013] Furthermore, the attachment device includes two first steel beams and two second steel beams,

[0014] The two first steel beams are arranged symmetrically and opposite to each other in the transverse direction, and the outer sleeve column can be passed through the space between the two first steel beams. A connecting component is provided at the bottom of the first steel beam for fixed connection with the floor slab. The first steel beam contacts the floor through the connecting component and can transfer the load force to the main beam;

[0015] The two second steel beams are symmetrically connected to the opposite inner sides of the two first steel beams to connect the two first steel beams.

[0016] Furthermore, the second steel beam is matched with a tongue that can only be flipped one-way, and the tongue that can only be flipped one-way is connected to an elastic member. When the outer sleeve column and the inner sleeve column are lifted and moved upward, the tongue that can only be flipped one-way contacts the second steel beam of the adjacent attachment device and can only be flipped downward and retracted into the inner sleeve column and the outer sleeve column, and can not block the lifting movement of the outer sleeve column and the inner sleeve column. When the tongue that can only be flipped one-way passes over the second steel beam, the elastic force of the elastic member causes the tongue that can only be flipped one-way to return to its original state and rest on the second steel beam, so that the outer sleeve column and the inner sleeve column are rested on the second steel beam through the tongue that can only be flipped one-way, thereby realizing load transfer.

[0017] Furthermore, the first reversing claw assembly and the second reversing claw assembly have the same structure, and both include a mounting box, a reversing claw, and a spring;

[0018] The installation box is provided with a through hole, and the installation box is movably sleeved on the inner sleeve column through the through hole. The reversing claw is rotatably arranged in the installation box. The reversing claw is an isosceles trapezoidal structure. Both ends of the spring are respectively connected to the reversing claw and the installation box to provide elastic force.

[0037] 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 described below with reference to specific diagrams.

[0038] See also Figure 1 , Figure 2 , which is a structural schematic diagram of the beam-based column-type climbing device and climbing method provided by the present invention.

[0039] As can be seen from the diagram, the beam-based sleeve column type climbing device and climbing method provided by the present invention include three components: two outer sleeve columns 100, a plurality of attachment devices 200, and an inner sleeve column 300.

[0040] The two outer sleeve columns 100 are symmetrically arranged and sequentially pass through the openings on both sides of the main beam 1. The tops of the two outer sleeve columns 100 are connected to the jacking platform 3 by setting a conversion beam 2. The load of the jacking platform 3 is transferred to the outer sleeve columns 100 through the conversion beam 1.

[0041] The attachment devices 200 are arranged at intervals and connected with the floor slab. The inner sleeve column 300 that can slide up and down is inserted into the outer sleeve column 100. Climbing blocks 310 are arranged at intervals on the inner sleeve column 300. The outer sleeve column 100 surface and the end surface of the inner sleeve column 200 away from the outer sleeve column 100 are provided with a one-way flip-over tongue 400 on the side of the attachment device 200 for being placed on the attachment device 200. The outer sleeve column 100 and the inner sleeve column 300 are pressed on the attachment device 200 through the tongue 400 to transfer the load to the main beam 1.

[0042] The bottom of the outer sleeve column 100 is connected with a first reversing claw assembly 500, the first reversing claw assembly 500 is connected with a telescopic assembly 600, the telescopic assembly 600 is connected with a second reversing claw assembly 700, the first reversing claw assembly 500, the second reversing claw assembly 700 is engaged with the climbing block 310 on the inner sleeve column 300;

[0043] The first reversing claw assembly 500 and the second reversing claw assembly 700 can form a first position and a second position by rotating. In the first position, the first reversing claw assembly 500 and the second reversing claw assembly 700 can only move upward in one direction relative to the climbing block 310. In the second position, the first reversing claw assembly 500 and the second reversing claw assembly 700 can only move downward in one direction relative to the climbing block 310.

[0044] Compared with the prior art, the telescopic assembly 600 of this solution is connected to the bottom of the outer sleeve column 100 and climbs with the outer sleeve column 100, which can realize the oil cylinder without reverse transportation, and there is no need to install and disassemble the oil cylinder and supporting oil pipes and other facilities back and forth, reducing the time and economic cost of manual installation and disassembly and reverse transportation of the oil cylinder on site. The device has the characteristics of light weight, easy operation, high economy, etc.

[0045] Specifically, the outer sleeve column 100 is a rectangular tube outer sleeve column, and the inner sleeve column 300 is inserted into the outer sleeve column 100 and is an H-shaped steel inner sleeve column. The end of the inner sleeve column 300 away from the outer sleeve column 100 is connected to the base 320, and the base 320 is connected to a one-way flippable tongue 400.

[0046] The attachment device 200 enables the outer sleeve column 100 and the inner sleeve column 300 to be attached to the main beam 1 .

[0047] like Figure 3 The attachment device 200 includes two first steel beams 210 and two second steel beams 220.

[0048] The two first steel beams 210 are arranged laterally symmetrically relative to each other, and the outer casing column 100 can be passed through the two first steel beams 210. A connecting component 211 is provided at the bottom of the first steel beam 210 for fixed connection with the floor slab. The first steel beam 210 is in contact with the floor through the connecting component 211, and the load force can be transmitted to the main beam 1.

[0049] The two second steel beams 220 are symmetrically connected to the inner sides of the two first steel beams 210 to connect the two first steel beams 210. The second steel beams 220 cooperate with the one-way flip-over tongue 400, which is connected to the elastic member. When the outer sleeve column 100 and the inner sleeve column 300 are lifted and moved upward, the one-way flip-over tongue 400 contacts the second steel beam 220 of the adjacent attachment device 200 and can only flip downward and retract to the outer sleeve column 100. The inside of the column 100 and the inner sleeve column 300 can not block the lifting movement of the outer sleeve column 100 and the inner sleeve column 300. When the tongue 400 that can only be flipped in one direction passes over the second steel beam 220, the elastic force of the elastic member makes the tongue 400 that can only be flipped in one direction return to its original state and rest on the second steel beam 220, so that the outer sleeve column 100 and the inner sleeve column 300 are placed on the second steel beam 220 through the tongue 400 that can only be flipped in one direction, thereby realizing the transfer of load.

[0050] In actual application, when the outer sleeve column 100 and the lifting platform 3 are lifted to the upper layer as a whole, the one-way-reversible latch 400 can be turned down and retracted into the outer sleeve column 100. When the outer sleeve column 100 falls back, the latch 400 can be placed on the attachment device 100 of the upper layer, thereby realizing the lifting of the lifting platform 3 as a whole by one layer; the latch 400 on the base 320 of the inner sleeve column 300 can be placed on the attachment device 6. When the lifting platform 3 is lifted to the upper layer, the latch 400 can be turned down and retracted into the inner sleeve column 300 when the inner sleeve column 300 is lifted. When the inner sleeve column 300 falls back, the latch 400 can be placed on the attachment device 200 of the upper layer, thereby realizing the lifting of the inner sleeve column 300 by one layer. In this way, the lifting of the lifting platform 3 can be realized layer by layer.

[0051] The first reversing claw assembly 500 and the second reversing claw assembly 700 are movably arranged on the inner sleeve column 300, and the telescopic assembly 600 is connected between the first reversing claw assembly 500 and the second reversing claw assembly 700. Figure 4 The first reversing claw assembly 500 and the second reversing claw assembly 700 have the same structure, and both include a mounting box 510, a reversing claw 520, and a spring 530;

[0052] A through hole is provided on the installation box 510, and the installation box 510 can be movably mounted on the inner sleeve column 300 through the through hole. The reversing claw 520 is rotatably arranged in the installation box 510. The reversing claw 520 is an isosceles trapezoidal structure. Both ends of the spring 530 are respectively connected to the reversing claw 520 and the installation box 510, and can provide elastic force.

[0053] When the reversing claw 520 rotates to one end between the two climbing blocks 310 and moves the end to contact the upper edge of the climbing block 310, the reversing claw 520 can move upward in one direction relative to the climbing block 310, and the spring 530 biases the reversing claw 520 toward the first position, as shown in FIG. Figure 4 At this time, it is the first position and the state of lifting the outer sleeve column 100 and the lifting platform 3.

[0054] As shown in FIG. 5 , by rotating the reversing claw 520 with opposite force, the reversing claw 520 can be driven to resist the elastic force of the spring 530 and rotate. When the reversing claw 520 rotates to the other end and is located between the two climbing blocks 310, by moving the end to contact the lower edge of the climbing block 310, the reversing claw 520 can move downward in one direction relative to the climbing block 310, and the spring 530 biases the reversing claw 520 toward the second position, which is now the second position and is in the state of lifting the inner sleeve column 300.

[0055] In actual application, when the outer sleeve column and the jacking platform are in the state, the inner sleeve column 300 remains stationary, and the reversing claw 520 is set in the first position. At this time, the reversing claw 520 can only move upward relative to the inner sleeve column 300. When the telescopic assembly 600 is extended, the reversing claw 520 in the second reversing claw assembly 700 is blocked when it contacts the climbing block 310. The telescopic assembly 600 is further extended, and the reversing claw 520 in the first reversing claw assembly 500 will flip over and pass over the climbing block 310 upward when it touches the climbing block 310. After the first reversing claw assembly 500 passes over the climbing block 310, the telescopic assembly 600 is retracted, and the first reversing claw assembly 500 will be blocked by the climbing block 310. The telescopic assembly 600 is further retracted, and the reversing claw 520 in the second reversing claw assembly 700 will flip over and pass over the climbing block 310 upward when it touches the climbing block 310. At this time, the lifting platform 3 has completed a climb, and the climbing height is the spacing between adjacent climbing blocks 310. The above actions are repeated continuously until the tongue 400 of the outer sleeve column 100 is placed on the attachment device 200 of the upper layer, and the lifting platform 3 has completed the climb of one floor.

[0056] When the building construction machine completes the climbing of one floor, it starts to lift the inner sleeve column 300 and sets the reversing claw 520 to the second position. At this time, the reversing claw 520 can only move downward relative to the inner sleeve column 300. When the telescopic assembly 600 is extended, the reversing claw 520 in the first reversing claw assembly 500 is blocked. The telescopic assembly 600 is further extended. When the reversing claw 520 in the second reversing claw assembly 700 hits the climbing block 310, it will flip over and go down over the climbing block 310. After the second reversing claw assembly 700 goes over the climbing block 310, the telescopic assembly 600 is retracted. The reversing claw 520 in the second reversing claw assembly 700 is blocked by the climbing block 310. The telescopic assembly 600 is further retracted. At this time, the inner sleeve column 300 is lifted upward along with the second reversing claw assembly 700 until the climbing block 310 hits the reversing claw 520 in the first reversing claw assembly 500. The reversing claw 520 in the first reversing claw assembly 500 flips over so that the climbing block 310 passes through the reversing claw 520. At this time, the inner sleeve column 300 completes a lift, and the lifting height is the distance between the two climbing blocks 310. The above actions are repeated continuously until the latch tongue 400 of the inner sleeve column 300 is placed on the attachment device 200 of the upper layer. At this time, the inner sleeve column 300 has completed the lifting of one floor.

[0057] For the beam-based sleeve column climbing device given in this example, this example further provides a corresponding climbing solution:

[0058] S1: When climbing the outer sleeve column and the jacking platform, the reversing claw 520 is set to the first position. At this time, the reversing claw 520 can only move upward relative to the inner sleeve column 300;

[0059] S2: The outer sleeve column and the lifting platform are lifted to a floor height by repeated extension and retraction movements of the telescopic assembly 600;

[0060] S3: until the tongue 400 of the outer sleeve column 100 is placed on the attachment device 200 of the upper floor, at which time the lifting platform 3 has completed the climbing of one floor;

[0061] S4: When the inner sleeve column is lifted, the reversing claw 520 is set to the second position, and at this time, the reversing claw 520 can only move downward relative to the inner sleeve column 300;

[0062] S5: The inner sleeve column 300 is lifted to the upper floor by repeated telescopic movement of the telescopic assembly 600;

[0063] S6: until the tongue 400 of the inner sleeve column 300 is placed on the attachment device 200 of the upper layer, the inner sleeve column 300 has completed the lifting of one floor, and the lifting of one floor is completed.
