[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] like Figure 1 and Figure 2A support system for double-layer wall construction shown in FIG. 1 includes an inner formwork support assembly 1 and an outer formwork support assembly 2 that are arranged relative to each other. The inner formwork support assembly 1 includes an inner wooden formwork 10, an inner secondary keel 11 horizontally arranged on one side of the inner wooden formwork 10, and an inner main keel 12 vertically arranged on one side of the inner secondary keel 11. The outer formwork support assembly 2 includes an outer wooden formwork 20, an outer secondary keel 21 horizontally arranged on one side of the outer wooden formwork 20, and an outer main keel 22 vertically arranged on one side of the outer secondary keel 21. A casting space is formed between the inner formwork support assembly 1 and the outer formwork support assembly 2. In a preferred embodiment, the inner main keel 12 and the outer main keel 22 have the same structure. Both are spliced ​​together by a plurality of keel monomers, and two adjacent keel monomers are connected by bolts for easy disassembly and assembly.

[0019] A water-stop screw 3 is arranged between the inner mold support assembly 1 and the outer mold support assembly 2, and the two ends of the water-stop screw 3 are fixed to the inner main keel 12 and the outer main keel 22 by mountain-shaped clamps. The water-stop screw 3 includes a first screw monomer 30 and a second screw monomer 31 that can be detachably connected. Water-stop steel plates 32 are fixedly arranged on the first screw monomer 30 and the second screw monomer 31, and the two water-stop steel plates 32 are respectively arranged in the inner and outer walls. Specifically, an internal thread connection portion is fixedly arranged at one end of the first screw monomer 30, and an external thread connection portion is fixedly arranged at one end of the second screw monomer 31. The external thread connection portion is threadedly connected to the internal thread connection portion, and the two can be quickly disassembled and connected, with good connection reliability.

[0020] A fiber cement board 4 is installed between the inner and outer formwork support assemblies 1 and 2, dividing the casting space into two independent sections. Within these sections is a wall reinforcement structure, with ladder bars and locating bars added to the reinforcement structure to ensure the designed spacing. Concrete is poured on both sides of the fiber cement board 4 to form a double-layer wall. Internal and external threaded connections are located within the fiber cement board 4. During construction, nuts and washers are used to securely connect the fiber cement board 4 to the first and second screw units 30 and 31, securing the installation position of the fiber cement board 4. The nuts and washers are inserted from one side of the external and internal threaded connections.
