The cooperation of the first and second nuts with the screw allows for quick adjustment of the position of the waterproof resin sheet and the support ribs, while facilitating the securement of the waterproof resin sheet.

[0054] Preferably, the steel structure support rib 1 has a plurality of first mounting holes arranged in a vertical direction for mounting screws; the waterproof resin plate 2 has a plurality of second mounting holes arranged in a vertical direction for mounting screws; each first mounting hole is arranged in a one-to-one correspondence with each second mounting hole, facilitating the installation and connection of the screws and the waterproof resin plate.

[0055] Preferably, the present invention further comprises two aluminum templates 3 provided on both sides of the outer wall of the steel structure; the aluminum templates 3 are provided with third mounting holes for engaging with screws, and the aluminum templates 3 are detachably connected to the waterproof resin plate 2. This facilitates the assembly and disassembly of the aluminum templates and effectively improves construction efficiency.

[0056] Preferably, a second gap is provided between the aluminum template 3 and the waterproof resin plate 2. The mixed material enters the second gap so that the mixed material covers the waterproof resin plate. After the mixed material solidifies, it can protect the waterproof resin plate and avoid damage to the waterproof resin plate.

[0057] Preferably, the aluminum formwork 3 comprises a pouring hole at the top for pouring the mixed material, a gate plate 31 that slides to open and close the pouring hole, a sliding groove connected to the gate plate 31 for sliding movement, and a first drive device that drives the gate plate 31 to slide and open or close the pouring hole.

[0066] S2: placing the waterproof resin plate 2 on both sides of the steel structure support rib plate 1 and fixing them together through a connecting device;

[0067] S3: Install the aluminum formwork 3, connect the aluminum formwork 3, the steel structure column and the foundation together to form an accommodation space for the steel structure support rib plate 1 and the waterproof resin plate 2;

[0068] S4: pouring the mixed material into the accommodating space by a pouring device to form a wall surface;

[0069] S5: Wait for the mixed material to solidify and remove the aluminum template 3.

[0070] Preferably, the steel structure column used in step 1 is provided with a first limiting groove for limiting the steel structure support rib 1 and a second limiting groove for limiting the waterproof resin plate 2. The first limiting groove and the second limiting groove facilitate the installation and fixation of the steel structure support rib and the waterproof resin plate.

[0071] Preferably, in step S4, the pouring device used includes a pouring pipe for pouring the mixed material; the pouring pipe has a pouring head that matches the pouring hole, which facilitates connection and effectively improves pouring efficiency.

[0072] Preferably, the pouring device further includes a stirrer 4 connected to the pouring pipe for mixing concrete and water-absorbing foamed particles. The stirrer 4 includes a mixing chamber for containing the concrete and water-absorbing foamed particles, a stirring blade 41 within the mixing chamber, and a second drive device for driving the stirring blade 41. The second drive device drives the stirring blade to rotate, so that the stirring blade fully mixes the water-absorbing foamed particles within the mixing chamber with the concrete, and the water-absorbing foamed particles are evenly mixed into the concrete. After pouring and forming, the water-absorbing foamed particles are evenly distributed, effectively improving the quality of the wall surface.

[0073] Preferably, the mixer 4 also has a concrete feed pipe 42 connected to the mixing chamber for admitting concrete, a water-absorbing foamed particle feed pipe 43 for admitting water-absorbing foamed particles, and a mixture discharge pipe 44 for discharging the mixture from the mixing chamber. The mixture discharge pipe 44 is connected to the pouring pipe. This facilitates the entry of concrete and water-absorbing foamed particles into the mixing chamber, as well as the discharge of the mixture from the mixing chamber, effectively improving mixing efficiency.

[0074] Preferably, the second driving device includes a second driving motor for driving the mixing blade 41 to rotate, and a transmission shaft connected between the second driving motor and the mixing blade 41. The driving motor drives the transmission shaft to rotate the mixing blade to mix the concrete and the water-absorbing foaming particles.

[0075] The step of pouring the mixed material in step S4 includes:

[0076] S41: The first driving device drives the gate plate 31 to slide and open the pouring hole, connecting the mixture discharge pipe 44 to the pouring hole;

[0078] S43: Open the concrete feed pipe 42 and the water-absorbing foamed particle feed pipe 43, allowing the concrete and the water-absorbing foamed particles to enter the mixing chamber for mixing;

[0079] S44: After the concrete and the water-absorbing foaming particles are mixed and stirred, they are discharged from the mixing chamber through the mixture discharge pipe 44 and poured through the pouring hole;

[0080] S45: After the mixture is poured until it covers the steel mesh and the steel structure support rib 1, the concrete feed pipe 42 and the water-absorbing foaming particle feed pipe 43 are closed, the connection between the mixture discharge pipe 44 and the pouring hole is disconnected, and the first driving device drives the gate plate 31 to slide and close the pouring hole;

[0081] S46: All the mixed materials in the mixing chamber are discharged and the second driving device is turned off.

[0082] When pouring through the mixing and pouring head, the mixing blades can fully mix the water-absorbing foam particles with the concrete, so that the water-absorbing foam particles are evenly mixed into the concrete. Before opening the concrete feed pipe and the water-absorbing foam particle feed pipe, the driving device is activated to drive the mixing blades to prevent the concrete and water-absorbing foam particles from entering the pouring hole for pouring without mixing. At the same time, it prevents the mixed material from solidifying and being unable to be discharged from the mixing chamber. Before closing the driving device, the mixed material in the mixing chamber is discharged to prevent the mixed material from solidifying in the mixing chamber and preventing damage to the mixing and pouring head. At the same time, it prevents the water-absorbing foam particles in the mixing chamber from absorbing moisture from the concrete, causing the mixed material to solidify quickly and being unable to be discharged from the mixing chamber.

[0083] The product form of the present invention is not limited to the illustrations and embodiments of this case. Any appropriate changes or modifications made by anyone with similar ideas should be deemed to be within the patent scope of the present invention.
