[0038] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0039] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0040] In addition, the terms "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0041] As Figure 1 shown is an embodiment of an arc-shaped arch connecting structure provided by the present application. In this embodiment, it comprises an arc-shaped arch, which is composed of left and right plane door frames 10, two arch door bodies 11 in the middle and arc-shaped door frames 31 on the upper and lower sides. The plane door frame 10 is fixedly connected with the curtain wall keel 13 in the curtain wall through the keel connecting mechanism, the arch door body 11 is slidingly connected with the arc-shaped door frame 31 through the sliding assembly, and the arc-shaped door frame 31 is fixedly connected with the curtain wall body 30 through the wall connecting mechanism.

[0042] It should be noted that when installing a large arc-shaped arch in an actual curtain wall building, an installation space for the arc-shaped arch will be reserved, and the left and right sides of the installation space will be adapted to the plane door frame 10. A curtain wall body will be built by erecting a curtain wall body that is overall adapted to the plane door frame 10. Since the curtain wall body is in a vertical state, it can be directly built by the curtain wall keel 13. The plane door frame keel 34 is welded at the connection point of the curtain wall keel 13 to splice the plane door frame keel 34 into the plane door frame 10.

[0043] However, when fixing the arc-shaped arch on the upper and lower sides of the reserved installation space, there will be a curved arc. If the curtain wall is continued to be built using the curtain wall keel 13, the connection points of the arc-shaped curtain wall keel 13 will be unevenly stressed if they are directly connected to the arc-shaped door frame, which will easily affect the overall load-bearing capacity of the curtain wall building. Therefore, the upper and lower sides of the arc-shaped arch will be first built into an arc-shaped structure by the curtain wall keel 13, and then the curtain wall body 30 will be cast in the arc-shaped structure part. After improving the load-bearing capacity of the arc-shaped structure of the curtain wall, the arc-shaped door frame 31 will be connected to the curtain wall body 30.

[0044] As Figure 2 shown in FIG. 3, in the technical scheme, the keel connecting mechanism comprises staggered plane door frame keels 34, an L-shaped plate 23 is arranged on the plane door frame keel 34 near the connecting point, a long hole 24 is arranged on the L-shaped plate 23, an adjusting plate 16 is arranged on the long hole 24, a threaded hole is arranged on the adjusting plate 16, and a side plate of the long hole 24 is fixedly connected to the plane door frame keel 34 through the long hole 24 on the L-shaped plate 23 and the threaded hole on the adjusting plate 16; a first sleeve 17 is fixedly arranged on the connecting point of the curtain wall keel 13, a second sleeve 18 is sleeved in the first sleeve 17, a welding plate 14 is fixedly arranged on the second sleeve 18, and the welding plate 14 is used for welding the bottom plate of the L-shaped plate 23 on the welding plate 14.

[0045] Further, in the technical scheme, a limiting protrusion 28 is arranged on the side of the adjusting plate 16 in contact with the L-shaped plate 23, a first limiting hole 29 is arranged on the L-shaped plate 23 and matched with the limiting protrusion 28, and the adjusting plate 16 is used for adjusting the fixed height of the L-shaped plate 23 on the plane door frame keel 34.

[0048] It needs to be explained that, because the connecting angle between the curtain wall body 30 and the arc-shaped door frame 31 needs to be adjusted by the wall connecting mechanism when the curtain wall body 30 and the arc-shaped door frame 31 are connected, a gap will be left in the through hole 36 on the second extension rod 26 after the first extension rod 20 and the second extension rod 26 are adjusted. The gap in the through hole 36 is filled by the Z-shaped filling block 37 to prevent the second extension rod 26 from being bent due to the large pressure on the gap in the through hole 36 when the curtain wall body 30 and the arc-shaped door frame 31 are connected and there is no entity to fill the gap, causing safety problems.

The clamping spring 47 at one end of the fixing shaft 46 and the bearing 48 in the upper connecting plate 43 are connected with each other, so that the upper connecting plate 43 at the top of the arch door body 11 and the arc-shaped door frame 31 can be conveniently and movably installed, the arch door body 11 can be independently installed, and the mechanical connection between the arch door body 11 and the circular elevator car is not needed, so that the installation difficulty is reduced.
