[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0019] like Figure 1 As shown, a fully assembled building exterior protection connection reinforcement structure provided in this embodiment includes a plurality of risers 3 enclosed in a horizontal and vertical manner along the periphery of a floor slab 1. A protection cavity 6 is formed between the enclosed plurality of risers 3, in which an operator can work.

[0020] The bottom of the riser 3 is installed on the wall panel 2 through the connection node 4. The riser 3 passes through the floor 1 and extends above the floor 1. The plurality of risers 3 located above the floor 1 are connected by steel wires 5. The diameter of the hole on the floor 1 for the riser 3 to pass through is slightly larger than the outer diameter of the riser 3.

[0021] like Figure 2 , Figure 3The connection node 4 includes a sleeve 41, a screw 42, a connection plate 43 and a nut 44. The sleeve 41 is pre-buried in the wall panel 2, one end of the screw 42 is connected to the sleeve 41, and the other end passes through the floor 1 and extends above the floor 1. The connection plate 43 is radially fixed inside the riser 3, and a hole for fixing the nut 44 is provided on the connection plate 43. The nut 44 is threadedly connected to the screw 42, and the screw 42 is placed inside the riser 3. The sleeve 41 can directly use the sleeve used for installing prefabricated components in the wall panel 2.

[0022] The riser 3 is a steel pipe with a diameter of φ48 mm. The thickness of the connecting plate 43 is 2 mm. A sealing plate 32 is provided at the top of the riser 3. The connecting plate 43 is welded to the inner wall of the riser 3. The nut 44 is inserted into the hole of the connecting plate 43, and the nut 44 is welded to the connecting plate 43. The connecting plate 43 is arranged close to the lower end of the riser 3, firstly, it is arranged close to the screw 42, which is convenient for connection with the screw 42, and secondly, it is convenient for welding. The nut 44 can be welded to the connecting plate 43 first, and then the connecting plate 43 can be welded to the riser 3. In addition, when the riser 3 is screwed and installed, the rotation direction of the riser 3 is consistent with the locking direction of the screw 42 in the sleeve 41. Alternatively, the screw 42 threadedly fixed to the sleeve 41 can be fixed by spot welding first, so that there is no requirement for the rotation direction of the riser 3, that is, there is no requirement for the installation direction of the nut 44.
