Abstract

This invention proposes a steel structure welding and construction process, including the following steps: setting up steel structure columns and steel structure supporting stiffeners; welding the steel structure supporting stiffeners to the steel structure columns by electric welding; setting up a waterproof resin board to connect the waterproof resin, steel structure columns, and foundation to form a space for accommodating the steel structure supporting stiffeners; and pouring a mixture to cover the steel structure supporting stiffeners and the welded joint. In actual implementation, a mixture of concrete and water-absorbing foamed particles is poured outside the welded joint. After the mixture solidifies, it covers the welded joint within the wall, strengthening the connection between the steel structures and isolating the welded joint from the external environment, thus avoiding the influence of the external environment and slowing down the corrosion of the welded joint, making the weld more robust. At the same time, the water-absorbing foamed particles in the mixture can absorb moisture from the concrete, accelerating the solidification of the concrete.

[0015] S23. Welding and fixing: After the welding gun heats the welding rod, it welds and fixes the gap between the steel structure support stiffener and the first limiting groove.

[0016] S24. Weld protection treatment: After the weld has cooled, a mixture of materials is poured outside the weld to isolate it from the external environment.

[0017] The steel structure column also has a second limiting groove to limit the waterproof resin board.

[0018] The steel structure support stiffener has multiple through holes for the mixture to pass through.

[0019] The steel structure support stiffener and the waterproof resin board are connected together by a connecting device, which includes a screw connecting the steel structure support stiffener and the waterproof resin board, a first nut located on both sides of the steel structure support stiffener to lock the steel structure support stiffener, and a second nut located on both sides of the waterproof resin board to lock the waterproof resin board.

[0020] The steel structure support stiffener has multiple first mounting holes for installing screws arranged vertically; the waterproof resin board has multiple second mounting holes for installing screws arranged vertically; each first mounting hole corresponds to each second mounting hole.

[0021] There is a gap between the waterproof resin board and the steel structure support ribs.

[0022] The waterproof resin board has multiple evenly distributed ventilation holes.

[0023] The waterproof resin board is provided with a pouring hole for pouring the mixture, a gate for opening and closing the pouring hole, a sliding groove connected to the gate for the gate to slide, and a first driving device for driving the gate to slide open or close the pouring hole; the gate is formed with a corresponding hole corresponding to the pouring hole.

[0026] The sealing head includes an elastic tube; the elastic tube has a closed inner hole, one end of which is connected to a leak-proof rigid tube.

[0027] The leak-proof component also has a housing that mates with the threaded pouring hole.

[0028] Leak-proof rigid pipes and sealing heads are fixedly installed inside the housing.

[0029] The leak-proof rigid pipe gradually tapers from the inlet to the outlet.

[0030] In step S4, the pouring device used includes a pouring pipe for pouring concrete; the pouring pipe has a pouring head that matches the pouring hole.

[0031] The pouring device also includes a mixer connected to the pouring pipe; the mixer has a mixing chamber for mixing concrete and water-absorbing foamed particles, mixing blades inside the mixing chamber, and a second drive device for driving the mixing blades; the mixer also has a concrete feed pipe connected to the mixing chamber for supplying concrete into the mixing chamber, a water-absorbing foamed particle feed pipe for supplying water-absorbing foamed particles into the mixing chamber, and a mixture discharge pipe for discharging the mixture from the mixing chamber.

[0048] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0049] like Figure 1-5 As shown, a steel structure welding and construction process includes the following steps:

[0050] S1: Fix multiple steel structure columns 1 on the foundation, and vertically install steel structure support plates 2 between two steel structure columns 1;

[0051] S2: Weld the steel structure support stiffener plate 2 to the steel structure column 1 together by electric welding;

[0052] S3: The waterproof resin board 3 is placed on both sides of the steel structure support stiffener 2, and the waterproof resin board 3 and the steel structure support stiffener 2 are connected together by a connecting device; at the same time, the waterproof resin board 3, the steel structure column 1 and the foundation are connected to form a space for accommodating the steel structure support stiffener 2.

[0053] S4: The mixture, mainly composed of concrete and water-absorbing foamed particles, is poured into the accommodating space through the pouring device. The mixture covers the steel structure support stiffener 2 and the welded joints. After the mixture solidifies, it forms the steel structure exterior wall.

[0054] In practice, a mixture of concrete and water-absorbing foamed particles is poured outside the weld joint. After the mixture solidifies, it encapsulates the weld joint within the wall, reinforcing the connection between the steel structures. At the same time, it isolates the weld joint from the external environment, preventing its impact and slowing down corrosion, thus making the weld stronger. In addition, the water-absorbing foamed particles in the mixture can absorb moisture from the concrete, accelerating its solidification.

[0055] Preferably, the steel structure column 1 has a first limiting groove for limiting the position of the steel structure supporting stiffener 2. The first limiting groove positions and fixes the steel structure supporting stiffener 2, while also facilitating welding.

[0056] Preferably, the welding step in step S2 includes:

[0057] S21. Surface cleaning: Set a bevel at the position where the steel structure support stiffener plate 2 needs to be welded, grind the bevel to remove rust, oil, water, paint and debris from the bevel surface and surrounding area; grind the first limiting groove to remove rust, oil, water, paint and debris from the first limiting groove surface and surrounding area.

[0058] S22. Drilling and fixing: Drill holes in the side wall of the first limiting groove and the steel structure support plate 2, and fix the steel structure column 1 to the steel structure support plate 2 by screws, bolts or threaded rods.

[0059] S23. Welding and fixing: After the welding gun heats the welding rod, it welds and fixes the gap between the steel structure support stiffener plate 2 and the first limiting groove.

[0060] S24. Weld Joint Protection: After the weld joint has cooled, a mixture of materials is poured over it to isolate the weld joint from the external environment. In practice, cleaning the bevel and the first limiting groove removes rust, oil, water, paint, and other debris from the weld joint, resulting in a stronger and more stable weld. Simultaneously, the drilling positions are fixed, thus securing the steel structure support ribs to the steel structure columns and facilitating welding. Pouring the mixture over the weld joint isolates it from the external environment, preventing weld damage due to corrosion and effectively reinforcing the connection between the steel structure support ribs and the steel structure columns.

[0061] Preferably, the steel structure column 1 also has a second limiting groove for positioning the waterproof resin board 3. The waterproof resin board is positioned and fixed by the second limiting groove.

[0062] Preferably, the steel structure support stiffener 2 has multiple through holes for the mixture to pass through. The mixture entering the through holes strengthens the connection between the steel structure support stiffener and the mixture after solidification.

[0063] Preferably, the steel structure support rib 2 and the waterproof resin board 3 are connected together by a connecting device. The connecting device includes a screw rod connecting the steel structure support rib 2 and the waterproof resin board 3, first nuts located on both sides of the steel structure support rib 2 to lock the steel structure support rib 2, and second nuts located on both sides of the waterproof resin board 3 to lock the waterproof resin board 3. The cooperation of the first nuts, second nuts, and screw rod further secures the waterproof resin board, facilitating pouring.

[0064] Preferably, the steel structure support rib plate 2 has multiple first mounting holes for installing screws arranged vertically; the waterproof resin board 3 has multiple second mounting holes for installing screws arranged vertically; each first mounting hole corresponds to each second mounting hole. This facilitates the installation and connection of the screws and the waterproof resin board.

[0065] Preferably, there is a gap between the waterproof resin board 3 and the steel structure support stiffener 2. The connection between the components is reinforced by filling the gap with a mixture.

[0066] Preferably, the waterproof resin board 3 has a plurality of evenly distributed vent holes 32. In actual implementation, a gel film is formed by applying gel to the outside of the waterproof resin board to seal the vent holes. After the mixture solidifies, the gel film is peeled off and the wall dries faster through the vent holes.

[0067] Preferably, the waterproof resin board 3 is provided with a pouring hole for pouring the mixture, a gate 31 for opening and closing the pouring hole, a sliding groove connected to the gate 31 for sliding the gate 31, and a first driving device for driving the gate 31 to slide open or close the pouring hole; the gate 31 has a corresponding hole corresponding to the pouring hole. By driving the gate to slide in the sliding groove through the first driving device, the pouring hole can be quickly opened or closed, making the operation simple, convenient and fast.

[0068] Preferably, the first driving device includes a threaded seat disposed on the gate plate 31, an adjusting screw cooperating with the threaded seat, and a drive motor for driving the adjusting screw to rotate; the threaded seat includes an adjusting nut cooperating with the adjusting screw. The drive motor drives the adjusting screw to rotate, and the cooperation between the screw and the threaded seat drives the gate plate to slide open or close the pouring hole, making operation simple, convenient, and quick.

[0069] Preferably, the waterproof resin board 3 also has a leak-proof component for sealing the pouring hole; the leak-proof component includes a leak-proof rigid pipe 41; the leak-proof rigid pipe 41 has an inlet and an outlet communicating with the inlet; the leak-proof component also has a sealing head disposed at the outlet and sealing the outlet. By setting a sealing head at the outlet to seal the outlet, the pouring hole is sealed, thereby preventing the mixture from flowing out of the pouring hole when the pouring head is pulled out.

[0070] Preferably, the sealing head includes an elastic tube 42; the elastic tube 42 has 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 sealing the outlet; when the pouring head is connected, the pouring head extends into the inner hole along the inlet towards the outlet, squeezing the sidewall of the elastic tube, causing the sidewall of the elastic tube to elastically deform and open the inner hole, allowing the pouring head to pass through the inner hole for pouring; when the pouring head is removed, the sidewall of the elastic tube recovers, sealing the inner hole; the elastic tube is made of rubber material.

[0071] Preferably, the leak-proof component also has a housing 43 that mates with the threaded connection of the pouring hole. The mating of the housing with the pouring hole facilitates the installation of the leak-proof component.

[0072] Preferably, the leak-proof rigid tube 41 and the sealing head are fixedly disposed inside the housing 43. The housing protects the leak-proof rigid tube and the sealing head, preventing damage to the leak-proof components. At the same time, the housing applies compressive force to the elastic tube, keeping the inner hole of the elastic tube in a closed state.

[0073] Preferably, the leak-proof rigid pipe 41 gradually tapers from the inlet to the outlet. This makes the leak-proof rigid pipe funnel-shaped, facilitating the insertion of the casting pipe into the inner hole.

[0074] Preferably, in step S4, the pouring device includes a pouring pipe for pouring the mixture; the pouring pipe has a pouring head that matches the pouring hole. This facilitates connection and effectively improves pouring efficiency.

[0075] Preferably, the pouring device further includes a mixer 5 connected to the pouring pipe; the mixer 5 has a mixing chamber for mixing concrete and water-absorbing foamed particles, mixing blades 51 located in the mixing chamber, and a second driving device for driving the mixing blades 51; the mixer 5 also has a concrete feed pipe 52 connected to the mixing chamber for supplying concrete into the mixing chamber, a water-absorbing foamed particle feed pipe 53 for supplying water-absorbing foamed particles into the mixing chamber, and a mixture discharge pipe 54 for discharging the mixture from the mixing chamber. When pouring by the mixer, the mixing blades can fully mix the water-absorbing foamed particles with the concrete, so that the water-absorbing foamed particles are evenly mixed into the concrete; after pouring and molding, the water-absorbing foamed particles are evenly distributed, effectively improving the quality of the wall surface, and at the same time, the water-absorbing foamed particles absorb water, accelerate the drying of the wall, and improve construction efficiency.

[0076] Preferably, the second driving device includes a drive motor that drives the stirring blade 51 to rotate, and a transmission shaft connected between the drive motor and the stirring blade 51. The drive motor drives the transmission shaft, causing the stirring blade to rotate.

[0077] Preferably, the step of pouring the mixture in step S4 includes:

[0078] S41: The first drive device drives the gate 31 to slide open the pouring hole and connects the mixed material discharge pipe 54 to the pouring hole;

[0079] S42: The second drive device drives the stirring blade 51 to rotate;

[0080] S43: Open the concrete feed pipe 52 and the water-absorbing foamed particle feed pipe 53 to allow the concrete and water-absorbing foamed particles to enter the mixing chamber for mixing.

[0081] S44: After the concrete is mixed with the water-absorbing foamed particles, it is discharged from the mixing chamber through the mixture discharge pipe 54 and poured through the pouring hole;

[0082] S45: After pouring the mixture to cover the steel mesh and steel structure support plate 2, close the concrete feed pipe 52 and the water-absorbing foamed particle feed pipe 53, disconnect the mixture discharge pipe 54 from the pouring hole, and drive the gate plate 31 to slide and close the pouring hole.

[0083] S46: Discharge all the mixture in the mixing chamber and turn off the second drive device. When pouring using the mixer, the mixing blades thoroughly mix the water-absorbing foamed granules with the concrete, ensuring the granules are evenly incorporated. Before opening the concrete feed pipe and the water-absorbing foamed granule feed pipe, activate the drive device to drive the mixing blades to prevent unmixed concrete and granules from entering the pouring hole. This also prevents the mixture from solidifying and becoming unable to be discharged from the mixing chamber. Discharge the mixture in the mixing chamber before turning off the drive device to prevent solidification and damage to the mixer. This also prevents the mixture from rapidly solidifying due to the water-absorbing foamed granules absorbing moisture from the concrete, thus preventing it from becoming unable to be discharged from the mixing chamber.

[0084] The product form of the present invention is not limited to the illustrations and embodiments shown in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of the present invention.
