[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model discloses a sunken roof drainage gutter.

[0022] This utility model provides, for example Figure 1-3The sunken roof drainage gutter shown includes a gutter body 1 and flanges 2. Flanges 2 are fixed to both sides of the gutter body 1. Multiple bolts 3 are threaded onto the inner wall of the gutter body 1. U-shaped columns 4 are located on the inner wall of the gutter body 1. Multiple U-shaped grooves 5 are located at the top of the gutter body 1. A fixing rod 6 is threaded onto one side of each U-shaped groove 5. A wall 7 is located at the bottom of each U-shaped groove 5. The gutter body 1 is fixed to the wall 7 via the U-shaped grooves 5. This sunken roof drainage gutter, through scientific structural design and coordinated component operation, achieves the core functions of efficient rainwater collection, orderly discharge, safe crossing of steel columns, and leak prevention. Its working principle revolves around four major systems: structural support, drainage guidance, fixed connection, and leak prevention. These systems work together to form a complete roof drainage solution, effectively solving the installation difficulties and low drainage efficiency problems caused by steel column obstruction in traditional gutters. In the structural support system, the gutter body 1, as the core load-bearing component, is made of 201 stainless steel with a thickness of 1.5mm, combining the advantages of strength and corrosion resistance. The 201 stainless steel material has excellent oxidation resistance, resisting long-term erosion from roof rainwater and avoiding the rust problems of traditional carbon steel gutters. Its 1.5mm thickness ensures the gutter is not easily deformed when bearing the weight of rainwater, roof load, and installation stress, providing a stable structural foundation for drainage. U-shaped columns 4 on the inner wall of the gutter further enhance structural stability. These columns are fixed to the inner wall of the gutter body 1 with bolts 3, forming a multi-point support structure that disperses pressure on the gutter under water accumulation, preventing dents or breakage due to excessive local stress. Especially at the sinking section crossing the steel column, the U-shaped columns 4 effectively enhance the gutter's resistance to deformation, ensuring the integrity of the drainage channel. The drainage guidance system is the core of efficient drainage, designed around the entire process of "collection-guidance-crossing-discharge." The flanges 2 fixed on both sides of the gutter body 1 play a crucial guiding role. The height of the flanges 2 is optimized to both prevent rainwater overflow and guide roof rainwater along the roof slope into the gutter. When rainwater flows from the roof to the edge of the gutter, the water-blocking structure formed by the flange 2 confines the rainwater within the gutter area, preventing rainwater from dripping directly onto the factory wall 7 or the ground and causing leakage. Addressing the issue of steel columns in steel-structured factory buildings obstructing continuous gutter installation, the gutter adopts a recessed design that spans the steel columns. The recessed section smoothly transitions with the gutter body 1, forming a continuous drainage channel. Rainwater can flow naturally along the slope of the gutter through the recessed section, preventing water accumulation dead zones due to the presence of steel columns and ensuring unobstructed drainage. The fixed connection system achieves a reliable connection between the gutter and the roof through multiple fixing structures, ensuring long-term stability. Multiple U-shaped grooves 5 at the top of the gutter cooperate with fixing rods 6 to form the main connection structure between the gutter and the wall 7. The U-shaped grooves 5 are evenly spaced at 1m intervals. This spacing design ensures even stress distribution on the gutter, avoiding loosening or deformation caused by stress concentration at local fixing points.During installation, the U-shaped locking groove 5 engages with the pre-installed mounting bracket on the wall 7 and is secured by tightening the fixing rod 6 on one side. The threaded connection between the fixing rod 6 and the U-shaped locking groove 5 has a self-locking characteristic, resisting the influence of external forces such as wind and vibration on the roof, ensuring that the gutter does not shift during long-term use. Multiple bolts 3 on the inner wall of the gutter are used to reinforce the connection between the gutter and the roof support structure. The bolts 3 pass through the gutter body 1 and are fixed to the roof purlins or support frame, forming a double fixing mode of "top U-shaped locking groove 5 + inner bolts 3," further enhancing the gutter's installation stability and preventing loosening due to water flow impact or temperature changes. The leak-proof protection system comprehensively blocks rainwater leakage paths through material selection and structural design. The 201 stainless steel material used in the gutter body 1 has excellent water tightness, and its smooth surface reduces the porosity for rainwater penetration. The 1.5mm thick plates are welded at the joints to ensure tight seams, avoiding the gap leakage problems that are common with traditional bolt 3 splicing. The waterproof layer 8, fixedly installed on one side of the gutter, is a key reinforcement measure for preventing leakage. Waterproof layer 8 uses a waterproof material highly compatible with stainless steel and fits tightly against the outer wall of the gutter at the contact point with the roof structure, forming a continuous waterproof barrier. When a small amount of rainwater accidentally seeps into the connection between the gutter and the roof, waterproof layer 8 effectively prevents further infiltration into the factory building, minimizing the risk of leakage. Simultaneously, the coordinated installation of the flange 2 with the roof's corrugated steel panels and flashing further enhances the leak-proof effect. The flange 2 is pressed into the underside of the roof structure to form a superimposed seal, reducing the possibility of rainwater seeping in through the joints. In actual operation, the various systems work together to form a complete drainage cycle: rainwater from the roof flows towards the gutter under the influence of gravity and the roof slope, and the flange 2 guides the rainwater into the gutter body 1; the rainwater flows along the internal slope of the gutter towards the drain outlet, smoothly crossing the steel column through the sunken section without water accumulation; the gutter body 1 maintains structural stability under the support of the U-shaped column 4 and the fixing system, and the stainless steel material and waterproof layer 8 work together to prevent rainwater leakage; finally, the rainwater is discharged into the downpipe through the drain outlet at the end of the gutter, completing the roof drainage process. This design not only solves the problem of steel column crossing, but also improves drainage efficiency and service life through structural optimization, achieving the goal of "one-time installation and long-term stable operation," providing a reliable guarantee for roof drainage of steel structure factory buildings.

[0023] To extend service life, such as Figure 1-3 As shown, the gutter body 1 is made of 201 stainless steel.

[0024] And for greater durability, such as Figure 1 As shown, the thickness of the gutter body 1 is 1.5mm.

[0025] And for better fixation, such as Figure 3 As shown, the interval between the multiple U-shaped buckles 5 is 1m.

[0026] Finally, for better waterproofing, such as Figure 2 As shown, a waterproof layer 8 is fixedly provided on one side of the gutter body 1.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
