Description

Technical Field

[0001] This invention relates to the technical field of metal roof waterproofing joint construction in building engineering, specifically to a fixing structure and fixing process for TPO waterproof membrane on the side of stainless steel gutters. Background Technology

[0002] Building gutters, as a key component of the roof drainage system, directly affect the safety, durability, and functionality of a building through their waterproofing performance. Their importance is mainly reflected in the following aspects: 1. Preventing structural damage and ensuring building safety: Structural erosion caused by leakage: If the gutters fail to waterproof, rainwater will continuously seep into the main building components such as concrete, steel, or wood structures. For concrete: Moisture will penetrate and cause steel reinforcement to corrode. The corroded steel expands in volume, causing the concrete to crack, peel, and reduce its load-bearing capacity. For steel structures: It will directly cause corrosion of load-bearing components such as joists and supports, weakening their structural strength. For wood structures: It will cause the wood to rot and mold, losing its load-bearing capacity. Freeze-thaw cycle damage: In cold regions, moisture that seeps into structural gaps expands in volume when freezing and contracts when thawing. This repeated freeze-thaw cycle will accelerate the cracking and pulverization of materials, causing irreversible damage. 2. Preventing indoor space flooding and ensuring functionality and property safety: This is the most direct and obvious risk. Failure of gutter waterproofing can lead to: 1. Rainwater backflow: In heavy rain, if drainage is not timely, rainwater may overflow the gutter. If the connection between the gutter and the roof material is not sealed tightly, rainwater will flow back into the room along the gaps. 2. Continuous leakage: Even if the gutter does not overflow, tiny gaps at the connection points can allow rainwater to seep in under wind pressure or capillary action. This ultimately damages ceilings, walls, and decorative layers (such as paint and wallpaper), as well as indoor appliances, furniture, and stored goods, resulting in significant economic losses. 3. Maintaining insulation performance and reducing energy consumption: Most modern buildings have an insulation layer on the roof. If gutter waterproofing fails, moisture can penetrate the insulation layer (such as rock wool or glass wool): Once the insulation material becomes damp, its insulation performance will drop sharply because water has a much higher thermal conductivity than still air. This ultimately leads to a decrease in the building's ability to stay warm in winter and cool in summer. To maintain the indoor temperature, the energy consumption of the heating or cooling system will increase significantly, resulting in energy waste and increased operating costs. 4. Enhancing System Reliability to Cope with Extreme Weather: With climate change and the increasing frequency of extreme rainstorms and strong winds, higher demands are placed on the performance of building envelope systems. Gutter waterproofing systems, especially their connection points to the roof, must possess the following characteristics: Wind uplift resistance: The waterproof membrane must not be blown up or torn under strong winds. Hydrostatic pressure resistance: Effectively prevent rainwater backflow when water accumulates in a short period. Durability: Withstand long-term exposure to sunlight, rain, and temperature fluctuations, maintaining stable performance.

[0003] In existing technologies, the TPO waterproof membrane on the sides of stainless steel gutters is typically fixed by interlocking with the roof flashing. This connection method has the following drawbacks: TPO has poor sealing between itself and the gutter, which can easily lead to rainwater leakage. Insufficient wind uplift resistance; the roll material is prone to falling off in strong winds. When the gutters are not draining properly or when rainwater overflows the gutters, rainwater backflow can easily occur, causing indoor leaks.

[0004] Patent document CN115538710A discloses a method for installing retractable wind-resistant gutters, including: gutter keel installation, gutter bottom plate installation, rock wool installation, stainless steel gutter installation, gutter side steel pressure plate installation, gutter TPO laying, glass wool, roof panel installation, and flashing installation. The gutter keel installation method includes: using a total station to measure and lay out lines on the main purlins, measuring the three-dimensional coordinates of the main gutter keel, installing the main gutter keel according to the measured coordinates, adjusting the position and elevation of the main gutter keel, and fixing the main gutter keel. Then, tack welding of the secondary keel of the gutter, i.e., 50mm square tubing and 50mm angle steel, spaced 1 meter apart, is performed. After tack welding, full welding is carried out to ensure the theoretical curvature of the gutter is met. The welding process must ensure uniform weld seams, and excess weld slag is removed and anti-corrosion treatment is applied.

[0005] In existing patent documents, utility model patent with authorization announcement number CN211143536U discloses a waterproof structure for a metal roof gutter. It includes an original U-shaped gutter and two metal roof panels inclined at both sides of the top of the original U-shaped gutter. The metal gutter also includes a U-shaped channel and two inclined plates at both sides of the top of the U-shaped channel. The cross-section of the metal gutter is funnel-shaped, with the U-shaped channel nested inside the original U-shaped gutter. The two inclined plates are respectively erected on the two metal roof panels, and XPS extruded polystyrene board is filled between the inclined plates and the metal roof panels. The outer surfaces of the metal roof panels and the metal gutter are provided with a "four-coat, one-cloth" waterproof structural layer. The U-shaped channel and the two inclined plates are integrally formed or welded together.

[0006] The newly added metal gutter in the aforementioned patent document can increase the drainage flow area and solve the problems of unreasonable original design, insufficient drainage, rainwater overflow, easy backflow into the room, rusting of many connecting parts, and increased construction costs due to complex construction process steps.

[0007] Therefore, optimizing and improving the existing TPO fixing structure and fixing process on the side of the gutter is a problem worth studying. Summary of the Invention

The galvanized support members are 50-100mm wide and spaced apart at intervals of 500-800mm.

The top of the stainless steel socket-type fixing component is welded to the stainless steel gutter, and its groove is flush with the outer side of the galvanized support component.
