[0056] Preferably, there is a first gap between the steel structure support ribs 1 and the waterproof resin plate 2. The mixture entering the first gap can strengthen the connection between the steel structure support ribs and the waterproof resin plate after solidification.

[0057] Preferably, the steel structure supporting rib plate 1 has a plurality of first through holes for the mixed material to pass through. The mixed material entering the first through holes can strengthen the connection between the steel structure supporting rib plate and the mixed material.

[0058] Preferably, the waterproof resin plate 2 has a plurality of second through holes for the mixed material to pass through. The mixed material entering the second through holes can strengthen the connection between the waterproof resin plate and the mixed material.

[0059] Preferably, the steel structure support ribs 1 and the waterproof resin sheet 2 are connected together by a connecting device, which includes a screw connecting the steel structure support ribs 1 and the waterproof resin sheet 2, a first nut located on either side of the steel structure support ribs 1 to lock the steel structure support ribs 1, and a second nut located on either side of the waterproof resin sheet 2 to lock the waterproof resin sheet 2. The cooperation of the first and second nuts with the screw allows for quick adjustment of the position between the waterproof resin sheet and the support ribs, while facilitating the securement of the waterproof resin sheet.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] Preferably, the aluminum template 3 has multiple groups of pouring holes for pouring the mixed material, and the multiple groups of pouring holes are distributed along the vertical direction on the aluminum template 3; each group of pouring holes includes two pouring holes arranged horizontally. The two horizontally arranged pouring holes can effectively speed up the pouring efficiency.

[0064] Preferably, the aluminum formwork 3 further comprises a gate plate 31 disposed at each group of casting holes and slidingly opening and closing the respective group of casting holes, a sliding groove 32 connected to the gate plate 31 for sliding the gate plate 31, and a first drive device for driving the gate plate 31 to slide and open or close the casting holes. The gate plate 31 is formed with holes corresponding to each group of casting holes. The first drive device drives the gate plate to slide within the sliding groove, thereby quickly opening or closing the casting holes, making operation simple, convenient, and fast.

[0065] Preferably, the first drive device includes a threaded seat mounted on the gate plate 31, an adjustment screw that cooperates with the threaded seat, and a drive motor that drives the adjustment screw to rotate. The threaded seat includes an adjustment nut that cooperates with the adjustment screw. The drive motor rotates the adjustment screw, and the screw and threaded seat cooperate to drive the gate plate to slide and open or close the casting hole, making operation simple, convenient, and quick.

[0066] Preferably, the aluminum formwork 3 further includes a leak-proof member for sealing the pouring hole; the leak-proof member includes a leak-proof rigid tube 41; the leak-proof rigid tube 41 has an inlet and an outlet communicating with the inlet; and the leak-proof member further includes a sealing head disposed at the outlet to seal the outlet. By providing the sealing head at the outlet to seal the outlet, the pouring hole is sealed, preventing the mixed material from flowing out of the pouring hole when the pouring head is removed.

[0067] Preferably, the closing head includes an elastic tube 42 having a closed inner hole 421, one end of which is connected to the leak-proof rigid tube 41. When the pouring head is not connected, the inner hole is closed, thereby blocking the outlet. When the pouring head is connected, the pouring head extends into the inner hole along the inlet toward the outlet, squeezing the sidewalls of the elastic tube. The sidewalls elastically deform, opening the inner hole, and the pouring head passes through the inner hole to pour. When the pouring head is removed, the sidewalls of the elastic tube return to their original shape, sealing the inner hole. The elastic tube is made of rubber.

[0068] Preferably, the leak-proof part further comprises a shell 43 which is threadedly matched with the casting hole. The matching of the shell and the casting hole facilitates the installation of the leak-proof part.

[0069] Preferably, the leakproof hard tube 41 and the closing head are fixedly arranged in the housing 43. The housing protects the leakproof hard tube and the closing head to avoid damage to the leakproof component. At the same time, the housing applies an extrusion force to the elastic tube to keep the inner hole of the elastic tube in a closed state.

[0070] Preferably, the leak-proof hard pipe 41 tapers gradually from the inlet toward the outlet, so that the leak-proof hard pipe is funnel-shaped, making it easier for the pouring pipe to extend into the inner hole.

[0071] A construction method for an assembled lightweight steel structure factory building comprises the following steps:

[0072] S1: Fix a plurality of steel structure columns on the foundation, and fix the steel structure support rib 1 between two steel structure columns;

[0073] S2: placing the waterproof resin plate 2 on both sides of the steel structure supporting rib plate 1 and fixing them together through a connecting device;

[0074] S3: Install the aluminum formwork 3, connect the aluminum formwork 3, the steel structure column and the foundation together to form an accommodating space for the steel structure support rib plate 1 and the waterproof resin plate 2;

[0075] S4: pouring the mixed material into the accommodating space by a pouring device to form a wall surface;

[0076] S5: Wait for the mixed material to solidify and remove the aluminum template 3.

[0077] In the actual implementation process, aluminum formwork is used for pouring. The repeated use of aluminum formwork can effectively reduce the generation of construction waste and protect the environment. At the same time, the aluminum formwork is light in weight, convenient for construction and installation, and effectively improves construction efficiency.

[0078] 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.

[0079] Preferably, in step S4, the pouring device used includes a pouring pipe 5 for pouring the mixed material; the pouring pipe 5 has a pouring head matching each group of pouring holes, which facilitates connection and effectively improves pouring efficiency.

[0080] Preferably, the pouring head is mounted on a support frame 6 located outside the aluminum formwork 3; the support frame 6 has a first guide rail connected to the pouring head and vertically arranged, a sliding seat 61 that carries the first guide rail, and a base 62 on which the sliding seat 61 is mounted; the base 62 has a second guide rail connected to the sliding seat 61 and extending toward the aluminum formwork 3; the support frame 6 also includes a first cylinder that drives the pouring head to slide along the first guide rail and a second cylinder that drives the sliding seat 61 to slide along the second guide rail. The first cylinder drives the pouring head to move along the first guide rail so that the pouring head is aligned with the pouring hole; the second cylinder drives the sliding seat to slide along the second guide rail so that the pouring head is inserted into the pouring hole, automatically completing the connection between the pouring pipe and the pouring hole, reducing dependence on personnel while effectively speeding up the connection efficiency.

[0081] Preferably, the pouring device further includes a stirrer 7 connected to the pouring pipe 5 for mixing the concrete and the water-absorbing foamed particles. The stirrer 7 includes a mixing chamber for containing the concrete and the water-absorbing foamed particles, a stirring blade 71 within the mixing chamber, and a second drive device for driving the stirring blade 71. 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.

[0082] Preferably, the agitator 7 further comprises a concrete feed pipe 72 connected to the mixing chamber for feeding concrete into the mixing chamber, a water-absorbing foamed particle feed pipe 73 for feeding water-absorbing foamed particles into the mixing chamber, and a mixture discharge pipe 74 for discharging the mixture from the mixing chamber. The mixture discharge pipe 74 is connected to the pouring pipe 5. This facilitates the entry of concrete and water-absorbing foamed particles into the mixing chamber and the discharge of the mixture from the mixing chamber, effectively improving mixing efficiency.

[0083] Preferably, the second driving device includes a second driving motor for driving the mixing blade 71 to rotate, and a transmission shaft connected between the second driving motor and the mixing blade 71. The driving motor drives the transmission shaft to rotate the mixing blade to mix the concrete and the water-absorbing foaming particles.

[0084] Preferably, the step of pouring the mixed material in step S4 includes:

[0085] S41: The first driving device drives the gate plate 31 at the bottom to slide and open the pouring hole. The first cylinder drives the pouring head to rise along the first guide rail so that the pouring head is aligned with the pouring hole. The second cylinder drives the sliding seat 61 to slide along the second guide rail so that the pouring head is inserted into the pouring hole.

[0086] S42: The second driving device drives the stirring blade 71 to rotate;

[0087] S43: Open the concrete feed pipe 72 and the water-absorbing foamed particle feed pipe 73 to allow the concrete and the water-absorbing foamed particles to enter the mixing chamber for mixing;

[0088] 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 74 and enter the pouring pipe 5.

[0089] S45: Concrete is poured through the pouring pipe 5 until it covers the edge of the pouring hole. The pouring is stopped, and the second cylinder drives the sliding seat 61 to slide along the second guide rail to move the pouring head out of the pouring hole. The first driving device drives the gate 31 to slide and close the pouring hole at the bottom.

[0090] S46: The first cylinder drives the pouring head to slide along the first guide rail, so that the pouring head rises to the position of another group of pouring holes; the first driving device drives the gate 31 to open the other group of pouring holes;

[0091] S47: Repeat the action and complete the pouring from bottom to top; after the pouring is completed, the second cylinder drives the sliding seat 61 to reset, and the first cylinder drives the pouring head to reset.

[0092] S48: All the mixed materials in the mixing chamber are discharged and the second driving device is turned off.

[0093] The mixing blades thoroughly mix the water-absorbing foam particles with the concrete, ensuring they are evenly incorporated into the concrete. The drive mechanism is activated before the concrete and water-absorbing foam particle feed pipes are opened to drive the mixing blades. This prevents the concrete and water-absorbing foam particles from entering the pouring holes unmixed for pouring. This also prevents the mixture from solidifying too quickly and becoming unable to be discharged. Before shutting down the drive mechanism, the mixture is discharged from the mixing chamber to prevent it from solidifying within the mixing chamber and damaging the mixing and pouring head. This also prevents the water-absorbing foam particles within the mixing chamber from absorbing moisture from the concrete, causing the mixture to solidify quickly and becoming unable to be discharged. The mixture is poured from bottom to top to prevent excessive pressure from the upper pouring port, which can prevent air bubbles from being trapped and deteriorating the quality of the resulting wall. The pouring holes are opened according to the level of the mixture during pouring to prevent the pressure required from the pouring head from increasing due to the pouring holes being below the level of the mixture, which can reduce pouring efficiency.

[0094] 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.
