Regarding the above-mentioned related technologies, there are defects such as full-frame construction platforms that require a large amount of steel, a large amount of installation and disassembly work, and labor-intensive; beam-type construction platforms need to be attached to the building structure and have high requirements for the building structure; lattice column-type construction platforms only provide temporary support but cannot provide a construction work surface; lattice columns and beams are used in combination, which requires a large amount of steel, has high installation and positioning requirements, and is difficult to dismantle. Summary of the invention

[0003] In order to solve the above-mentioned defects, the present application provides a self-lifting heavy-load construction platform and a construction method thereof.

[0004] In the first aspect, the present application provides a self-lifting heavy-load construction platform, which adopts the following technical solution: it includes: support columns, which are provided in at least two groups, each group is provided with two support columns; a main beam, which is connected between the two support columns in the same group; a plurality of auxiliary beams, which are connected between adjacent main beams; a plurality of support plates, which are provided and connected to the auxiliary beams to form a support platform; a lifting assembly, which is connected to the top of the support column and is used to lift the main beam; and a formwork assembly, which is connected to the auxiliary beam and is used to support the formwork.

[0005] By adopting the above technical solution, the support columns are constructed using standard sections, and the lifting components are used to lift the main beam, thereby improving the stability of the construction platform. At the same time, the construction platform does not need to be built on the building; the setting of the formwork assembly realizes the support of the building formwork, and the support plate and the auxiliary beam are used in combination to provide a construction platform for the staff, thereby improving the safety of construction.

[0006] Preferably, the lifting assembly includes: a fixed rod, fixedly connected to the top of the support column; a connecting rod, fixedly connected to both ends of the lower surface of the main beam in the length direction; an electric hoist, fixedly connected to the fixed rod and detachably connected to the connecting rod.

[0007] By adopting the above technical solution, the hook of the electric hoist is hooked on the connecting rod. At this time, the electric hoist is started, and the electric hoist drives the fixed rod to rise, thereby realizing the lifting of the main beam. When the supporting platform needs to be disassembled, the setting of the electric hoist makes it easy for the staff to disassemble the supporting platform, thereby achieving the effect of facilitating the use of the staff.

[0008] Preferably, a first connecting member for connecting the main beam and the auxiliary beam is provided between them, and the first connecting member includes: a connecting plate, fixedly connected to the upper surface of the main beam; two clamping plates are provided, and the two clamping plates are parallel and vertically fixedly connected to the upper surface of the support plate; the connecting part of the auxiliary beam is inserted between the two clamping plates.

[0009] By adopting the above technical solution, the connecting part of the auxiliary beam is inserted between the two clamping plates during use. At this time, a pin is used to penetrate the connecting part of the clamping plate and the auxiliary beam, thereby realizing the connection of the auxiliary beam, achieving the effect of facilitating use by the staff.

At the same time, the keel support is used to be inserted into the formwork keel to improve the stability of the support.

[0014] Preferably, a locking ring is sleeved on the circumferential outer wall of the adjusting rod, and the locking ring is located between the adjusting plate and the keel support.

[0022] S5. Installation of protective components;

[0023] S6. Install the mold frame assembly.

[0024] By adopting the above technical solution, the setting of the electric hoist can facilitate the staff to lift the main beam, thereby reducing the workload of the staff; at the same time, the setting of the support column, main beam and auxiliary beam can facilitate the staff to design different forms and specifications for different buildings to meet the structural requirements of different heights and different spans.

[0025] Preferably, in step S1, during foundation construction, different foundation construction methods are determined according to different construction locations; when the support column installation location has a foundation or a concrete floor, the bearing capacity is checked, and if the requirements are met, the support column is fixed by an anchor connection method; when there is no foundation at the support column installation location, a new foundation is designed; when there is a basement at the support column installation location, the floor slab is reinforced before the foundation is established.

[0026] By adopting the above technical solution, the foundation construction method is determined according to different construction environments, and the construction period is shortened and the construction cost is reduced as much as possible while meeting the bearing capacity requirements.

[0027] Preferably, in step S2, during the construction of the support columns, different methods are adopted according to the platform design specifications; when two groups of support columns are provided, the tops of the support columns all adopt the standard sections of the side column tops; when multiple groups of support columns are provided, the two groups of support columns at both ends of the length direction of the supporting platform adopt the standard sections of the side column tops, and the remaining support columns use the standard sections of the middle column tops.

[0028] By adopting the above technical solution, the setting of support columns can meet the needs of construction platforms with different spans.

[0029] Preferably, in step S3, when the main beam is lifted by an electric hoist, when the lifting height is less than 6 meters, a group of lifting components is arranged at the top of each support column; when the lifting distance is greater than 6 meters, two groups of lifting components are arranged at the top of each support column to realize alternating lifting of the main beam.

[0030] By adopting the above technical solution, the setting of the lifting components can meet the needs of construction platforms at different heights.
