Description

TECHNICAL FIELD

[0001] The present application relates to the field of building construction, in particular to an automatic jacking platform for a large building air building machine.

[0002] The present application also relates to a construction method based on the automatic jacking platform. BACKGROUND

[0003] The air building machine and its construction technology is an industrialized intelligent construction of high-rise residential cast-in-place reinforced concrete by mechanical operation and intelligent control. One of its obvious features is that all the processes are concentrated and completed layer by layer in the air. Therefore, it is also called "air building machine". The equipment platform simulates a mobile building factory, moves the factory to the construction site, cooperates with the existing commercial concrete supply chain and concrete high-altitude pumping technology by mechanical operation and intelligent control, and performs synchronous construction of the ground above structure main body and insulation finish integrated plate by layer, which is a cast-in-place construction technology that replaces manual work with machines to realize the overall cast-in-place construction of high-rise and super high-rise reinforced concrete.

[0004] However, the existing building machine has a small tower crane coverage range, a narrow operation space, and the tower crane on the building machine platform is generally located at a relatively edge position, and the coverage capacity of the central position of the large building is limited. If the jib is lengthened, the risk of overturning is increased, which is not conducive to construction safety. SUMMARY

[0005] The purpose of the present application is to provide an automatic jacking platform for a large building air building machine, which is beneficial to adding a jacking platform in the middle of a large building, making it easy to enter the coverage range of the tower crane at the edge position of the building machine, improving the transfer range of materials in the middle of the large building, shortening the length of the jib of the tower crane at the edge position of the building machine, and ensuring construction safety.

[0006] Another purpose of the present application is to provide a construction method based on the automatic jacking platform for a large building air building machine, which is beneficial to building and realizing the circulating jacking operation.

[0007] The automatic jacking platform for a large building air building machine comprises

[0008] a base;

[0009] a platform installed on the upper side of the base;

[0010] a push plate slidingly installed on both sides of the base;

[0011] a diagonal brace with a lower end hinged to the upper side of the push plate;

[0012] The expansion platform is slidably connected on both sides of the platform and extends out of the platform, and the bottom surface of the part of the platform outside the platform is hingedly connected to the upper end of the inclined brace;

[0013] The first positioning seat is fixed on both sides of the base and is located below the push plate;

[0014] The lower end of the lead screw is rotatably installed on the first positioning seat, and the lead screw is threadedly connected through the push plate;

[0015] The second positioning seat is fixed on both sides of the base and is rotatably penetrated by the lead screw, and is spaced above the first positioning seat and the push plate;

[0016] The motor is fixed on both sides of the base, and the output shaft of the motor is fixedly connected to the lead screw;

[0017] The positioning rod is slidably penetrated through the push plate, and the upper and lower ends of the positioning rod are fixed on both sides of the base;

[0018] The jacking mechanism is installed at the bottom of the base.

[0019] With such a structure, the expansion platform can be opened and retracted to increase the coverage of the platform, and the opening of the expansion platform facilitates the entry of the tower crane into the coverage range of the tower crane, which is beneficial for the transfer of construction materials. The retraction of the expansion platform can adjust the center of gravity and enhance the ability of the platform to resist adverse weather.

[0020] As a further improvement of the automatic jacking platform, a sliding rail groove is provided on the platform, and a moving block is slidably fitted in the sliding rail groove. The moving block is fixed at the bottom of the mounting seat. The tower crane is installed at the top of the mounting seat. The push rod is hingedly connected to one end of the mounting seat on both sides, and the other end of the push rod is hingedly connected to a fixed block.

When the expansion platform is opened, the tower crane can be extended to expand the coverage of the tower crane. When the expansion platform is retracted, the tower crane is retracted, which is beneficial for resisting 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 for additional standard sections.

[0037] S5: When the longitudinal and transverse shear walls of the second floor elevator hall and the longitudinal and transverse shear walls of the stairwell are completed, the bracket on the bottom surface of the fixed clamp base is installed to complete the stress point conversion, and then the bracket on the bottom surface of the original position fixed clamp base is removed to release the limit of the movable clamp base, and then the movable clamp base is retracted, and then the bracket on the bottom surface of the movable clamp base is installed to complete the stress point conversion for the next round of jacking, and the bracket on the bottom surface of the original position movable clamp base is removed to release the limit of the fixed guide rail, thereby completing a cycle of jacking operation, so that the tower crane on the platform gradually rises with the progress of the construction.
