[0002] Non-planar facade designs are very common in building construction. Irregular facades of the main structure can be achieved using irregular facade formwork. However, the installation process of the facade panels is relatively complex, requiring a construction platform that is compatible with the facade. It also requires a large number of connection nodes with the main structure, and involves many angles during construction. Due to the lack of support, the facade formwork is relatively difficult to erect. Summary of the Invention

[0003] The purpose of this invention is to provide a unified construction platform system and method for attaching to irregular facades, and to provide a construction operation platform for irregular facades for constructing decorative panels on irregular facades.

[0005] More preferably, the length of the two adapter pieces connected vertically is adapted to the spacing between building structural layers, and the length of a single adapter piece is 1.5~2.5m.

[0006] Furthermore, the adapter includes a central box-shaped anti-deformation structure and connecting lugs on two opposite sides of the central anti-deformation box-shaped structure. The central anti-deformation box-shaped structure has a square cross-section, and there are three connecting lugs on each side of the central anti-deformation box-shaped structure. Each connecting lug is arranged along the length of the central anti-deformation box-shaped structure. The connecting lugs connected to the connecting lug plate are provided with a number of evenly spaced strip holes, and the connecting lugs connected to the frame lug plate are provided with a number of evenly spaced bolt holes.

[0007] Furthermore, the connecting ear plate includes a base plate and two ear plates spaced apart. The bottom surface of the base plate away from the ear plates is provided with a snap-fit ​​piece. The grooved embedded part includes a track groove and an embedded rod connected to the bottom of the track groove. There are at least two track grooves, and the upper and lower track grooves are embedded in the reinforced concrete structure in parallel.

[0008] Furthermore, the two ear plates are inserted between the two connecting ear pieces and fixed by screws, and the thickness of the ear plates is equal to the distance between the two connecting ear pieces.

[0009] Furthermore, the rotary adapter connector includes connecting rods on both sides and pins for connecting the connecting rods on both sides.

[0011] In addition, each base plate is provided with at least four snap-fit ​​pieces, which are arranged in a rectangular array. The snap-fit ​​pieces are T-shaped, with the horizontal part of the T-shaped structure extending into the track groove and the vertical part extending out of the track groove to connect with the base plate.

[0013] A method for constructing a construction platform system attached to an irregular facade, characterized by comprising the following steps: S1, the grooved embedded part is prefabricated in the factory along with the connecting ear plate; S2, the grooved embedded parts and connecting ear plates are constructed upwards along with the building structure layer; S3, the adapter is connected to the connecting ear plate, and the angle of the single adapter is adjusted according to the preset angle using a protractor; S4: Adjacent adapters located on a straight line are connected via a fixed adapter connector; adjacent adapters located on a broken line or curve are connected via a rotary adapter connector.

[0014] Compared with the prior art, the present invention has the following features and beneficial effects: This application uses external adapters of different heights to connect the single frame of the operating platform. These frames can be made of steel or aluminum alloy. The strength of the materials and the size of the components of each frame are designed according to the weight of the upper and lower adapters, taking into account both horizontal wind loads and seismic loads, while also considering a certain amount of impact loads and safety redundancy.

[0015] The two adapters in this application are connected by a pin shaft to adapt to different vertical angles of the facade; the side of the single frame of the operating platform away from the main structure is connected by a frame connector with built-in rigid springs to limit the maximum separation distance of the outer side of the single frame of the operating platform, ensuring that the separation distance is not too large during use. The maximum distance can be adjusted by the elastic stiffness of the built-in spring of the outer connector.

[0016] This application uses a track-type embedded part within the main structure to connect with a connecting ear plate. The connecting ear plate connects the adapter to the main structure. The embedded part is a slot-type embedded part with a high fault tolerance rate, which can effectively solve the problem of construction deviation. It can be extended along the outer edge of the main structure or set at points. In the horizontal direction, the side of the adapter closer to the main structure is connected to the slot-type embedded part by a pin bolt. In the vertical direction, the adapter is connected by a rotary adapter connector and a fixed adapter connector to adapt to the needs of zigzag and straight frame structures. The connector with a built-in hard spring on the side of a single frame away from the main structure limits the maximum separation distance of the outer side of the hanger to ensure its functional realization.
