[0045] During use, first, the U-shaped card 4 is pre-buried before pouring the F+2 layer of concrete. After the concrete pouring is completed and the strength is reached, the formwork is removed and the I-beam is installed and fixed through the U-shaped card 4; and the main body connecting aluminum mold unit 1 and the aluminum mold support rod 3 are installed in advance;

[0046] Afterwards, when constructing the ultra-high cantilevered balcony, the assembled aluminum formwork mechanism 100 is sent to the main body connection aluminum formwork unit 1 and the two are spliced ​​and fixed, and the support base 300 is fixed in the U-shaped card 4 at the same time, and then the angles of the telescopic rod 1 201 and the telescopic rod 202 are rotated, and the telescopic rod 1 201 and the telescopic rod 202 are controlled to extend and plug into the vertical card slot 301 and the oblique card slot 302 respectively, so as to realize the connection between the support assembly 200 and the support base 300, so that the telescopic rod 1 201, the telescopic rod 202 and the assembled aluminum formwork mechanism 100 form a stable fixed frame to support the assembled aluminum formwork mechanism 100, thereby forming an F+3-layer cantilevered balcony structure formwork support system, and carrying out steel bar construction, acceptance, and concrete pouring;

[0051] In the initial state, the telescopic rod 1 201 and the telescopic rod 202 are folded and stored close to the assembled aluminum mold mechanism 100 under the action of the cylinder 203, which can save space.

At the same time, the supplementary telescopic rod 204 is also connected to the cylinder 203, and the rotation of the supplementary telescopic rod 204 is controlled by the cylinder 203.

[0054] The remaining structures are the same as those of Example 1.

[0055] Example 3, reference Figure 7 , which is the third embodiment of the present invention, and this embodiment provides a method for constructing an ultra-high cantilevered balcony: the method comprises the following steps;

[0056] S1. By pre-embedded U-shaped card 4 in the main concrete structure layer 2 below the main connecting aluminum formwork unit 1;

[0057] The main concrete structure layer 2 has multiple layers, specifically divided into F, F+1, F+2, and F+3, wherein F+3 is the main connecting aluminum formwork unit 1, and at the same time, the F+2 layer concrete structure layer is provided with a plurality of aluminum formwork support rods 3 for supporting the main connecting aluminum formwork unit 1, and U-shaped cards 4 are pre-embedded before pouring the F+2 layer concrete.

[0058] S2. The support base 300 is fixed by a U-shaped card 4;

[0059] When pouring concrete for the main connecting aluminum formwork unit 1 of the F+3 layer, first fix the pipe sleeve in the supporting base 300 to the U-shaped card 4, insert the pipe sleeve into the U-shaped card 4, and fix the pipe sleeve using the U-shaped card 4, and retract the steel body 304 into the sleeve.

[0060] S3. By raising the assembled aluminum mold mechanism 100 and connecting the aluminum mold unit 1 to the main body for splicing;

[0061] The assembled aluminum mold mechanism 100 is installed with a lifting rope and fixed on the hook of the crane. The assembled aluminum mold mechanism 100 is raised by the crane until it reaches the height of the main body connected aluminum mold unit 1, and then the assembled aluminum mold mechanism 100 is spliced ​​and fixed to the main body connected aluminum mold unit 1.

[0062] Further, the scissor lift mechanism 5 can be used to lift the assembled aluminum mold mechanism 100, wherein there is a concrete layer extending outward on the F layer. When using the scissor lift mechanism 5, first mark the lifting position on the F layer, use a line to remind, and then push the scissor lift mechanism 5 to the line position and fix it;

[0063] The top of the scissors-type lifting mechanism 5 also has a sliding component 6, wherein the sliding component 6 can be made of a cylinder and a slide plate, wherein the cylinder is fixed to the top of the scissors-type lifting mechanism 5, and the slide plate is controlled by the cylinder to move relative to the scissors-type lifting mechanism 5 as a whole, and the assembled aluminum mold mechanism 100 is fixedly installed on the sliding component 6. When the scissors-type lifting mechanism 5 is used to send the assembled aluminum mold mechanism 100 to the main body connected aluminum mold unit 1 of the F+3 layer, the assembled aluminum mold mechanism 100 is first made higher than the main body connected aluminum mold unit 1, and then the pin plate of the assembled aluminum mold mechanism 100 is sent to the slot of the main body connected aluminum mold unit 1 through the sliding component 6, and then the height of the scissors-type lifting mechanism 5 is lowered so that the plug plate is plugged into the slot, thereby splicing and fixing the assembled aluminum mold mechanism 100 and the main body connected aluminum mold unit 1.

[0064] S4. The assembled aluminum mold mechanism 100 is supported by connecting the support assembly 200 to the support base 300;

At the same time, the scissor lift mechanism 5 can also be retracted and removed, and the scissor lift mechanism 5 can continue to be used in turnover construction, thereby saving manpower and material resources and improving efficiency.

[0066] S5. Assembling the aluminum mold mechanism 100 for dismantling and turnover use;

[0067] When the strength of the concrete poured at the main connecting aluminum formwork unit 1 reaches 100%, the ultra-high cantilever balcony formwork and its construction method are completely dismantled. First, the beam side formwork of the main connecting aluminum formwork unit 1 is manually dismantled, and the beam side formwork is the part with the slot 1-b. Then, the scissors-type lifting mechanism 5 is pushed into the initial drawing position of the F layer, and then raised to contact and support the assembled aluminum formwork mechanism 100. Then, the telescopic rod 1 201 and the telescopic rod 2 202 are retracted, and the support base 300 is disassembled from the F+2 layer at the same time. Finally, the assembled aluminum formwork mechanism 100 is lowered by the scissors-type lifting mechanism 5, and the assembled aluminum formwork mechanism 100 is removed. After that, the ultra-high cantilever balcony formwork is cleaned and continued to be used.
