Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a hoisting method for high-rise building construction. Background Art

[0002] Tower crane is the most commonly used lifting equipment on construction sites. It is connected in length (height) by standard sections, like an iron tower. It is also called a tower crane. It is used to lift construction materials such as steel bars, wooden slats, scaffolding pipes, etc. It is an indispensable equipment in construction. When the building area exceeds the operating radius of the tower crane, multiple tower cranes need to be installed to operate simultaneously. The more tower cranes there are, the higher the cost of installation, jacking, use, maintenance and disassembly. Therefore, there are still many problems in the lifting of construction materials, which need to be solved urgently.

[0003] Patent application 202110812011.X discloses a lifting method. By modifying the existing tower crane, upper and lower booms with different boom lengths are set on the same tower crane, and then building materials at different positions are lifted according to their different lengths. This does not require the installation of more tower cranes, reducing construction costs. At the same time, since the lengths of the booms are completely different and building materials at different positions are lifted according to their lengths, safety hazards when multiple tower cranes are used can be avoided, and building materials at different positions can be lifted at the same time to effectively improve lifting efficiency.

[0004] The technical solution of the above application still has limitations in operating radius. As the number of floors increases, the structure of the equipment jacking uses more steel, the jacking is more complicated, the maintenance and disassembly costs are high, and the investment cost is high. It is not suitable for high-rise building construction. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a lifting method for high-rise building construction.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A lifting method for high-rise building construction includes the following specific steps:

[0008] S1. Installation of lifting equipment: After the construction of the first floor of the building is completed, a walking lifting equipment is installed on the roof of the first floor;

[0009] S2. Construction of the climbing foundation: First, build the core area of the second floor. The lifting equipment uses its own jacking system to climb to the roof of the core area;

[0010] S3, lifting and transporting construction consumables with lifting equipment to the core and peripheral areas of building construction;

[0011] S4. Dismantling. Each component of the hoisting equipment is of a prefabricated type. The large components are lowered to the ground by the lifting hook of the hoisting equipment itself, and the last component is lowered to the ground by a small crane.

[0012] Preferably, the hoisting equipment includes a traveling structure, a tower column body, an external climbing frame, a crossbeam track, and a hoisting trolley.

[0013] Preferably, the tower column body is assembled from multiple standard sections. The number of tower column bodies is two. Independent external climbing frames are sleeved on the outer surfaces of the two tower column bodies. Independent traveling structures are installed at the bottoms of the two tower column bodies. The crossbeam track is fixedly connected to the two external climbing frames. The hoisting trolley is slidably installed on the crossbeam track, and a lifting hook is arranged on the lower side of the hoisting trolley.

[0014] Preferably, the tower column body is assembled from multiple standard sections. The number of tower column bodies is two. Independent external climbing frames are sleeved on the outer surfaces of the two tower column bodies. Independent traveling structures are installed at the bottoms of the two tower column bodies. The crossbeam track is slidably connected to the two external climbing frames. The hoisting trolley is slidably installed on the crossbeam track, and a lifting hook is arranged on the lower side of the hoisting trolley.

[0015] Preferably, a hydraulic jacking system is arranged inside the external climbing frame. The hydraulic jacking system includes a hydraulic cylinder. The outer wall of the cylinder of the hydraulic cylinder is fixedly connected to the external climbing frame. The telescopic end of the hydraulic cylinder is detachably fixed to the standard section. Oil is injected into the hydraulic cylinder. When the telescopic end of the hydraulic cylinder extends, it drives the external climbing frame to climb upward. Or when the telescopic end of the hydraulic cylinder contracts, it drives the external climbing frame to slide downward. The external climbing frame can be fixedly connected to the tower column body by bolts.

[0016] Preferably, the crossbeam track is assembled from steel brackets. Each steel bracket is adjacent to the next one end to end, and a long strip-shaped installation space that penetrates up and down is reserved in the middle.

And the crossbeam track can be respectively fixedly connected to the external climbing frame by bolts.

[0017] Preferably, a rope winding roller is arranged inside the hoisting trolley. The rope of the lifting hook is wound around the rope winding roller. The rotation of the rope winding roller releases and winds the rope, causing the lifting hook to move up and down. A guiding roller and a driving gear are arranged inside the hoisting trolley. A tooth groove matching the driving gear is arranged on the surface of the crossbeam track. The driving gear rolls along the tooth groove, driving the hoisting trolley to reciprocate left and right along the crossbeam track.

[0021] 2. The lifting equipment proposed in this application has a crossbeam track that can extend to the outside of the building, similar to an existing tower crane, so as to realize the lifting of building materials from the ground to the roof. At the same time, when dismantling, the lifting equipment can be split into unit modules, and each unit module can be lifted to the ground using its own lifting system, thereby achieving the effect of easy disassembly.

[0031] Embodiment 1

[0032] Referring to Figure 1-6 , a hoisting method for high-rise building construction, the special hoisting equipment used in this method includes a traveling structure 1, a tower column body 2, an external climbing frame 3, a cross beam track 4, and a hoisting trolley 5. The traveling structure 1 includes two forms, namely a track-type traveling mechanism and a roller-type traveling mechanism.

[0033] In this embodiment, the tower column body 2 is assembled by a plurality of standard sections 6. The number of tower column bodies 2 is two. Independent external climbing frames 3 are sleeved on the outer surfaces of the two tower column bodies 2. Independent traveling structures 1 are installed at the bottoms of the two tower column bodies 2. The cross beam track 4 is slidably connected to the two external climbing frames 3. The hoisting trolley 5 is slidably installed on the cross beam track 4. A lifting hook 7 is provided on the lower side of the hoisting trolley 5.

[0034] A hydraulic jacking system is provided inside the external climbing frame 3. The hydraulic jacking system includes a hydraulic cylinder. The outer wall of the cylinder of the hydraulic cylinder is fixedly connected to the external climbing frame 3. The telescopic end of the hydraulic cylinder is detachably fixedly connected to the standard section 6. When the hydraulic cylinder is filled with oil, the telescopic end of the hydraulic cylinder extends, driving the external climbing frame 3 to climb upward. Or, when the telescopic end of the hydraulic cylinder contracts, it drives the external climbing frame 3 to slide downward. The external climbing frame 3 can be fixedly connected to the tower column body 2 by bolts.

[0035] Referring to the attached Figure 6 , the cross beam track 4 is assembled by steel brackets. Each steel bracket is adjacent to the head and tail, and a long strip-shaped installation space 8 that penetrates up and down is reserved in the middle. The external climbing frame 3 is arranged in the installation space 8. Sliding wheels 9 are provided on the front and rear sides of the external climbing frame 3. The external climbing frame 3 is slidably connected to the cross beam track 4 through the sliding wheels 9, and the cross beam track 4 can be respectively fixedly connected to the external climbing frame 3 by bolts.

[0036] A rope winding roller is provided inside the hoisting trolley 5. The rope of the lifting hook 7 is wound around the rope winding roller. The rotation of the rope winding roller releases and winds the rope, causing the lifting hook 7 to move up and down. Guide rollers 10 and drive gears 11 are provided inside the hoisting trolley 5. Tooth grooves matching the drive gears 11 are provided on the surface of the cross beam track 4. The drive gears roll along the tooth grooves, driving the hoisting trolley 5 to reciprocate left and right along the cross beam track 4. The hoisting trolley 5 can perform hoisting operations on the core area 12 and the peripheral area 13.

[0037] It includes the following specific steps:

[0038] S1. Installation of the hoisting equipment. After the construction of the first floor of the building is completed, a walking hoisting equipment is installed on the top floor slab of the first floor.

[0039] S2. Construction of the climbing foundation. First, the core area of the second floor is constructed. The core area refers to a structure with a height of one floor near the inner side of the overall building, including the completion of the top floor slab of the second floor, and the peripheral area is reserved. During the construction process, the hoisting equipment moves horizontally in the peripheral area to hoist the building materials required for the core area. After the core area is completed, the standard components are lifted by the hoisting equipment, and the standard section support columns are fixedly installed on the surface of the top floor slab of the second floor. The crossbeam track is fixed to the standard section support columns, the tower column body is lifted, and the external climbing frame is driven by the hoisting trolley to move on the crossbeam track, so that the tower column body is moved to the top floor slab of the second floor. As shown in the attachment Figure 3 shown, the hoisting equipment uses its own jacking system to climb to the top floor slab of the core area.

[0040] S3. Hoisting and transferring building consumables by the hoisting equipment. For the construction of the peripheral area of the building, after the peripheral area of the second floor is completed, the core area of the previous time is constructed again, and so on. As the building rises layer by layer, the hoisting equipment climbs accordingly.

[0041] S4. Dismantling. Each component of the hoisting equipment is assembled. The large components are lowered to the ground by the lifting hook of the hoisting equipment itself, and the last component is lowered to the ground by a small crane.

[0042] Embodiment 2

[0043] Different from Embodiment 1, the tower column body 2 is assembled by a plurality of standard sections 6. The number of tower column bodies 2 is two. An independent external climbing frame 3 is sleeved on the outer surface of the two tower column bodies 2. An independent walking structure 1 is installed at the bottom of the two tower column bodies 2. The crossbeam track 4 is fixedly connected to the two external climbing frames 3. The hoisting trolley 5 is slidably installed on the crossbeam track 4. A lifting hook 7 is arranged on the lower side of the hoisting trolley 5. In this embodiment, in step S2, the hoisting trolley 5 cannot drive the external climbing frame 3 to move on the crossbeam track 4, but there are standard section support columns to support the hoisting equipment, which can also ensure that the hoisting trolley 5 can carry out hoisting operations on the core area 12 and the peripheral area 13, and ensure that the hoisting equipment climbs layer by layer as the building rises.

[0044] For the hoisting method proposed in this application, Embodiment 1 is superior to Embodiment 2. Refer to the attachment Figure 4, in Embodiment 1, the crossbeam track 4 can extend outwards from the building, similar to the existing tower crane, to realize the hoisting of building materials from the ground to the rooftop. At the same time, when the hoisting equipment is disassembled, it can be split into unit modules, and each unit module can be hoisted to the ground by its own hoisting system, thus achieving the effect of being easy to disassemble. It should be noted that the walking structure 1 can be fixedly connected to the building floor to ensure the stability of the equipment.

[0045] During the construction process of high-rise buildings, the height of the building is getting higher and higher. The hoisting equipment uses its own hoisting function and jacking system to achieve climbing with a large height difference. The use and occupancy of standard sections are less, reducing the construction cost. The hoisting equipment moves on the rooftop of the building, covering the entire construction area, and it is more convenient to hoist building materials to the destination, solving the problems of limited operation radius of the existing tower crane equipment, more structural steel used for jacking, and high maintenance cost for setting up multiple tower crane equipment at the same time.

[0046] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
