[0026] The above-mentioned aerial building machine for prefabricated buildings also includes a perimeter purlin 9; the perimeter purlin 9 is located below the truss beam 1 and is connected to the standard section 8.

[0027] In the above-mentioned aerial building machine for prefabricated buildings, an external rack 10 is installed below the truss beam 1. The external rack 10 is an external wall construction platform for workers to perform external wall operations. The number of external racks 10 is 1-2 layers.

[0030] The above-mentioned aerial building machine for prefabricated buildings is a large steel structure frame that is set outside the building and can be automatically lifted and lowered. The steel frame is highly integrated with mechanical components and multiple construction platforms with various lifting, transportation, decoration installation, and cloth functions. Through lattice steel pipe lifting columns and multiple independent horizontal purlins, it is combined into a large-scale special mechanical equipment that simulates a "mobile building factory".

Moreover, the scheme has superior practicality and wide applicability.

[0031] Example 2

[0032] The building process of the aerial building machine for prefabricated buildings described in Example 1 is described as follows.

[0033] Step 1: Use an external crane to install the six lattice lifting columns, truss beam 1, multiple horizontal steel purlins, gantry crane 11, crane moving track 2, concrete vertical transportation device 3, and concrete placing machine 4 of the aerial building machine. The six lattice lifting columns are arranged in a rectangular structure.

[0034] Step 2: Start building the first layer. The gantry crane 11 moves along the crane moving track 2 to the top of the prefabricated component, and extends the hook downward to hook up the prefabricated component.

[0035] Step three: The gantry crane 11 moves along the crane moving track 2 to a predetermined longitudinal position, and then the hook moves laterally along the gantry of the gantry crane 11 to transport the prefabricated component to the predetermined position, and then the manipulator 6 will also move along the manipulator moving track 7 to the periphery of the prefabricated component to temporarily fix the prefabricated component.

[0036] Step 4: After all vertical components are installed, start preparing the reinforcement and formwork for the vertical load-bearing columns, and then pour the concrete.

[0037] Step 5: After the construction of the vertical components is completed, start hoisting the horizontal components, and the construction of the first floor is completed.

[0038] Step 6: Through the hydraulic pump station, the telescopic rods of the six groups of hydraulic cylinders 11 are controlled to extend at the same time, and the standard section 8 connected to the telescopic rod is lifted to the preset height, and the standard section 8 is increased by horizontal advancement to complete one lifting, and the lifting is repeated until the truss beam 1, the crane moving track 2, and the manipulator moving track 7 reach the second-floor construction height.

[0039] Step 7: Repeat the construction process of the first layer to complete the construction of the second layer, and start installing the first layer of external racks under the truss beam 1. The external rack is an external wall construction platform for workers to perform external wall operations.

[0040] Step 8: Continue to lift the aerial building machine and start building the third floor, and install the second layer of racks under the first layer of racks, that is, a total of two layers of racks 10 are installed under the truss beam 1.

[0041] Step 9: So far, the installation of the aerial building machine is completed, and then the normal cycle begins, with the main components of the nth floor being hoisted and installed from the bottom to the top. The completed (n-1) floor and (n-2) floor can be used for exterior wall decoration and other construction operations through the two layers of external racks 10 under the truss beam 1, and the construction of all floors is completed in a cycle.

[0042] Step 10: After all floors are built, start to lower the height of the lifting columns, and use the hydraulic pump station to control the extension of the telescopic rods of the six groups of hydraulic cylinders 12 at the same time. The standard sections 8 connected to the telescopic rods are lifted to a preset height, and the standard sections 8 below the standard sections 8 connected to the hydraulic cylinders 12 are removed. By pushing out the standard sections 8 one by one, the height of the entire aerial building machine is gradually lowered. When it is lowered to the lowest height, the various components of the aerial building machine are removed by an external crane.

[0043] In step 2, the pre-storage position of the prefabricated components is on the ground below the narrow sides of the rectangular structure on both sides. The stacking requirements and sequence must meet the requirements of lifting to ensure smooth lifting and installation.

[0044] In step 4, the vertical load-bearing columns are cast in place and mainly bear vertical loads and certain overturning loads.

[0045] In step five, after the construction of the vertical components is completed, it means that the horizontal components can be hoisted and installed only after the strength of the cast-in-place vertical load-bearing columns reaches a certain requirement.

[0046] In step six, each lifting requires the hydraulic synchronizer to accurately and synchronously control the extension of all hydraulic cylinders 11. The lifting height, i.e., the floor height of the prefabricated building, is an integer multiple of the length of the standard section 8.

[0047] In step eight, the height of the two-layer external rack 10 is exactly the height of two floors, which allows workers to decorate the exterior walls of two floors at the same time, thereby improving construction efficiency.

[0048] In step ten, completing the construction of all floors means completing the construction, installation, and exterior wall decoration of all floors.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
