[0045] In order to further explain the technical solution of the present invention, it is described in detail below through specific embodiments.

[0046] like Figure 1-4As shown, a fireproof steel structure factory building includes a foundation and a steel structure outer wall located on the foundation and connected to the foundation. The steel structure outer wall includes a steel structure support rib 1 vertically arranged in the wall, two fire-resistant panels 2 located on both sides of the steel structure support rib 1 and fixedly connected to the steel structure support rib 1, and concrete covering the steel structure support rib 1 and the fire-resistant panels 2; the fire-resistant panels 2 are parallel to the steel structure support rib 1. In the actual implementation process, by setting fire-resistant panels on both sides of the steel structure support rib, concrete is poured to cover the steel structure support rib and the fire-resistant panels in concrete. When a fire occurs, the concrete and the fire-resistant panels isolate the steel structure support rib from the fire source, and also isolate the high temperature, thereby preventing the mechanical properties of the steel structure support rib from being significantly reduced under the action of high temperature and the collapse of the steel structure factory building. This effectively improves the fire resistance of the steel structure factory building and increases the service life of the steel structure building.

[0047] Preferably, there is a first gap between the steel structure support ribs 1 and the fireproof board 2. After the concrete entering the first gap solidifies, it can strengthen the connection between the steel structure support ribs and the fireproof board.

[0048] Preferably, the steel structure supporting rib plate 1 has a plurality of first through holes for concrete to pass through. Concrete entering the first through holes can strengthen the connection between the steel structure supporting rib plate and the concrete.

[0049] Preferably, the fireproof board 2 has a plurality of second through holes for concrete to pass through. Concrete entering the second through holes can strengthen the connection between the fireproof board and the concrete.

[0050] Preferably, the steel structure support rib 1 and the fireproof board 2 are connected together by a connecting device, which includes a screw connecting the steel structure support rib 1 and the fireproof board 2, a first nut located on both sides of the steel structure support rib 1 to lock the steel structure support rib 1, and a second nut located on both sides of the fireproof board 2 to lock the fireproof board 2. Through the cooperation of the first nut, the second nut and the screw, the position between the fireproof board and the support rib can be quickly adjusted, while facilitating the fixing of the fireproof board.

[0051] Preferably, the steel structure support rib 1 has a plurality of first mounting holes arranged in a vertical direction for mounting screws; the fireproof board 2 has a plurality of second mounting holes arranged in a vertical direction for mounting screws; and 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 fireproof board.

[0052] 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 fireproof board 2, thereby facilitating the assembly and disassembly of the aluminum templates and effectively improving construction efficiency.

[0053] Preferably, a second gap is provided between the aluminum formwork 3 and the fireproof board 2. Concrete enters the second gap so that the concrete covers the fireproof board. After the concrete solidifies, the concrete can protect the fireproof board and avoid damage to the fireproof board.

[0054] Preferably, the aluminum formwork 3 has multiple groups of pouring holes for pouring concrete, and the multiple groups of pouring holes are distributed along the vertical direction on the aluminum formwork 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.

[0055] 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 drive device for driving the gate plate 31 to slide and open or close the casting holes. The gate plate 31 is formed with corresponding holes corresponding to each group of casting holes. The 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.

[0056] Preferably, the drive device includes a threaded seat mounted on the gate 31, an adjustment screw that cooperates with the threaded seat, and a drive motor that drives the adjustment screw to rotate.

[0057] 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 connected to the inlet. The leak-proof member further includes a sealing head disposed at the outlet to seal the outlet.

[0058] Preferably, the closing head includes an elastic tube 42 having a closed inner hole, 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.

[0059] 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.

[0061] 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.

[0062] A construction method for an assembled lightweight steel structure factory building comprises the following steps:

[0063] S1: Fix a plurality of steel structure columns on the foundation, and fix the steel structure support rib 1 between two steel structure columns;

[0064] S2: The fire-resistant board 2 is arranged on both sides of the steel structure supporting rib 1 and fixedly connected together by a connecting device;

[0065] 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 1 and the fire-resistant board 2;

[0066] S4: pouring concrete into the accommodating space by a pouring device to form a wall surface;

[0067] S5: Wait for the concrete to solidify and remove the aluminum formwork 3.

[0068] 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.

[0069] 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 fireproof board 2. The first limiting groove and the second limiting groove facilitate the installation and fixation of the steel structure support rib and the fireproof board.

[0070] Preferably, in step S4, the pouring device used includes a pouring pipe 5 for pouring concrete; the pouring pipe 5 has a pouring head that matches each group of pouring holes, which facilitates connection and effectively improves pouring efficiency.

[0071] 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.

[0072] The step of pouring concrete in step S4 includes:

[0073] S41: The 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.

[0074] S42: 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.

[0075] S43: 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 driving device drives the gate 31 to open the other group of pouring holes;

[0076] S44: 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.

[0077] When pouring concrete, pouring from bottom to top can avoid the formation of bubbles due to excessive pouring from the pouring port at the top, which can prevent the air from being unable to be discharged, and prevent the quality of the cast wall from deteriorating; at the same time, open the corresponding pouring holes according to the plane of the concrete during pouring, so as to avoid the pressure required by the pouring head to increase due to the pouring holes being below the plane of the concrete, and reduce the pouring efficiency.

[0078] 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.
