Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to an automatic jacking platform for a large-scale aerial building construction machine.

[0002] The invention also relates to a construction method based on the automatic jacking platform. Background Art

[0003] The aerial building machine and its construction technology use mechanical operation and intelligent control to realize the industrialized intelligent construction of cast-in-place reinforced concrete for high-rise residential buildings. One of its obvious features is that the entire process is completed in the air layer by layer. Therefore, it is also called the "aerial building machine". The equipment platform simulates a mobile building factory, moves the factory to the construction site, and uses mechanical operation, intelligent control and other means to cooperate with the existing commercial concrete supply chain and concrete high-altitude pumping technology to carry out cast-in-place construction technology for the synchronous construction of the main structure and the integrated insulation facing panels above the ground layer by layer, using machines instead of manual labor to realize the overall cast-in-place construction of high-rise and super-high-rise reinforced concrete.

[0004] However, existing building construction machines have a small tower crane coverage range and a narrow operating space. In addition, the tower crane on the building construction machine platform is generally located relatively close to the side, and has limited coverage capacity for the middle part of a large building. If the boom is lengthened, the risk of overturning increases, which is not conducive to construction safety. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic jacking platform for a large-scale aerial building construction machine, which is conducive to adding a jacking platform in the middle of the large building, making it easy to enter the coverage range of the tower crane at the side of the building construction machine, which is conducive to improving the transportation range of materials in the middle of the large building, facilitating shortening the boom length of the tower crane at the side of the building construction machine, and ensuring construction safety.

[0006] Another object of the present invention is to provide a construction method based on the automatic jacking platform for the above-mentioned large-scale aerial building construction machine, which is conducive to the construction and implementation of cyclic jacking operations.

[0007] Regarding the technical subject of an automatic jacking platform for a large-scale aerial building construction machine, it includes Base; A platform mounted on the side of the base; Push plates, which are slidably mounted on both sides of the base; A diagonal brace, the lower end of which is hinged to the upper side of the push plate; an amplification platform, which is slidably connected to both sides of the platform and extends out of the platform, and the bottom portion of which is located outside the platform is hinged to the upper end of the diagonal support; A first positioning seat, which is fixed on both sides of the base and located below the push plate; A lead screw, the lower end of which is rotatably mounted on the first positioning seat and passes through the push plate in a threaded connection; A second positioning seat is fixed on both sides of the base and rotatably passed through by the lead screw, and is spaced above the first positioning seat and the push plate; The motor is fixed on both sides of the base, and its output shaft is fixedly connected to the lead screw; A positioning rod, which slides through the push plate and has upper and lower ends fixed on both sides of the base; The jacking mechanism is installed at the bottom of the base.

[0008] With such a structure, the augmented platform can be opened and retracted to increase the platform's coverage. When the augmented platform is opened, it is easy to enter the coverage of the building crane and facilitate the transportation of construction materials. When the augmented platform is retracted, the center of gravity can be adjusted to enhance the platform's ability to withstand adverse weather.

[0009] As a further improvement of the automatic lifting platform, a slide rail groove is arranged on the platform, and the slide rail groove is slidably adapted to be equipped with a moving block; the moving block is fixed at the bottom of the mounting seat; a tower crane is installed on the top of the mounting seat; one end of a push rod is hinged on both sides of the mounting seat, and the other end of the push rod is hinged with a fixed block, and the fixed block is fixed on the side of the amplification platform; the fixed block is slidably connected to the sliding rod, and the sliding rod is fixed on the side wall of the platform, the sliding rod is parallel to the side of the amplification platform, and the amplification platform is slidably plugged into the side wall of the platform; the side wall of the amplification platform is vertically plugged into the side wall of the platform.

[0010] With such a structure, a small tower crane can be installed on the augmented platform to form cross-coverage with the large tower crane of the building construction machine. When the augmented platform is opened, the tower crane can be extended to expand the coverage of the tower crane. When the augmented platform is retracted, the tower crane retracts to help protect against adverse weather. The platform allows the tower crane to be installed at a low position. After the platform realizes the jacking function, the height of the tower crane can be increased without the need to install extra standard sections. The added small tower crane makes the material transportation in the middle of a large building more flexible.

[0011] As a further improvement of the automatic lifting platform, the base has a cavity, the cavity is connected to the bottom surface, the bottom surface of the base has a circle of flanges, and the lifting mechanism includes: The fixed guide rail is installed on the bottom surface of the base and is arranged around a circle at intervals, and is in the form of a frame; a hydraulic cylinder mounted on the flange, with its piston sliding through the flange and extending into the fixed rail; A fixed card seat is fixedly mounted on the upper end of the fixed guide rail and is slid through by the piston of the hydraulic cylinder, with one end thereof extending horizontally out of the base; The movable clamping seat is slidably installed in the fixed guide rail and fixedly connected with the piston of the hydraulic cylinder.

[0012] With such a structure, the movable clamping seat is lifted by the hydraulic cylinder, and the movable clamping seat provides a reaction force, so that the base and the platform can be lifted.

[0013] As a further improvement of the automatic lifting platform, a space is reserved between the mounting seat and the platform, a universal ball is installed at the space, and the shell of the universal ball is embedded in the bottom of the mounting seat.

[0014] With this structure, the universal ball reduces friction and facilitates the movement of small tower cranes.

[0015] As a further improvement of the automatic jacking platform, a load-bearing mechanism is installed on the bottom surface of the platform, and the load-bearing mechanism includes a load-bearing column, a lower row of load-bearing rods and an upper row of load-bearing rods. The load-bearing column is fixedly installed on the bottom surface of the platform; one end of the lower row of load-bearing rods and the upper row of load-bearing rods are connected to the load-bearing column, and the other end is connected to the inner wall of the cavity of the base, and a belly rod is arranged between the lower row of load-bearing rods and the upper row of load-bearing rods.

[0016] By adopting such a structure and adding multiple load-bearing mechanisms, the interior of the base and the bottom surface of the platform are fully supported, which increases the overall rigidity. In addition, the rod structure support system avoids the problem of heavy deadweight of the solid structure, which helps to reduce the deadweight and facilitate jacking.

[0017] Regarding the technical topic of construction method, the specific steps are as follows: S1: When pouring the longitudinal and transverse shear walls of the elevator room on the first floor and the longitudinal and transverse shear walls of the staircase, set multiple embedded components at upper and lower intervals and left and right intervals on the shear walls; S2: After removing the formwork of the longitudinal and transverse shear walls of the elevator room on the first floor and the longitudinal and transverse shear walls of the stairwell, install the corbels on the embedded components; S3: A fixed card seat and a movable card seat are respectively placed on the upper and lower spaced corbels, and then the fixed card seat and the movable card seat are used to position the fixed guide rail 10 for assembly; the base is hoisted on the fixed guide rail, and then various components on the base are successively installed; S4: The lifting mechanism lifts up. When the bracket on the bottom of the movable card seat touches the lower end of the fixed guide rail, the base stops rising, reserving the construction space for the longitudinal and transverse shear walls of the second-floor elevator room and the longitudinal and transverse shear walls of the staircase, and the fixed card seat locates the embedded position of the second-floor embedded components; S5: After the construction of the longitudinal and transverse shear walls of the second-floor elevator room and the longitudinal and transverse shear walls of the stairwell is completed, a corbel is installed on the bottom of the fixed base to complete the force point conversion, and then the corbel on the bottom of the fixed base in the original position is removed, the limit of the movable base is released, and then the movable base is retracted, and then the corbel is installed on the bottom of the movable base to complete the force point conversion for the next round of jacking, and the corbel on the bottom of the movable base in the original position is removed, and the limit of the fixed guide rail is released, thereby completing a cycle of jacking operation, so that the tower crane on the platform gradually rises as the construction progresses.

[0018] As a further improvement of the construction method, the embedded components include embedded steel plates, embedded bolts and embedded nuts, the embedded nuts are welded to the back of the embedded steel plates; holes corresponding to the positions of the embedded nuts are drilled on the embedded steel plates; the embedded bolts pass through the embedded steel plates via the embedded nuts.

[0019] With such a structure, the embedded components can provide multiple installation points, and the threaded connection method is easy to disassemble.

[0020] As a further improvement of the construction method, the corbel includes a first angle steel and an I-beam; a hole is punched on the first angle steel, and the hole is connected to the part of the embedded bolt passing through the embedded steel plate and tightened with a first nut; the first angle steel is fixed in two rows at intervals, and the inner end of the I-beam is clamped between the two angle steels; the upper and lower flanges of the I-beam are fixed to the first angle steel by a first bolt and nut assembly, and a second angle steel is arranged between the web of the I-beam and the embedded steel plate, and the second angle steel is connected to the part of the embedded bolt passing through the embedded steel plate and tightened with a first nut, and the second angle steel and the I-beam are tightened by a second bolt and nut assembly; a sleeve is also threadedly connected to the embedded bolt passing through the second angle steel, and the sleeve is threadedly connected to the anchor rod to extend the length, an anchor plate is arranged at the outer end of the I-beam for compression, the anchor plate is passed through the anchor rod and tightened with a second nut.

[0021] Such a structure allows the I-beam to be installed stably, the anchor plate is convenient for applying prestress, and an inclined support leg can be added to the bottom of the I-beam to lean against the shear wall; the corbel is connected as a whole by threaded connection for easy disassembly.

[0022] As a further improvement of the construction method, lifting ears are provided at both ends of the anchor plate, and the lifting ears are fixedly connected with steel strands, and the upper ends of the steel strands are fixed to the embedded bolts with anchors.

[0023] With such a structure, the steel strands are convenient for hanging the ends of the I-beams, so that the I-beams as a whole are more stable.

[0024] As a further improvement to the construction method, the I-beams are arranged at intervals and can be penetrated by the piston of the hydraulic cylinder.

[0025] With such a structure, the bracket does not affect the use of the piston of the hydraulic cylinder.

[0026] The present invention is conducive to adding a jacking platform in the middle of a large building, making it easy for the platform to enter the coverage range of a tower crane at the side of a building construction machine, which is conducive to improving the transfer range of materials in the middle of the large building, facilitating shortening the boom length of the tower crane at the side of the building construction machine, and ensuring construction safety.
