[0002] With the widespread application of modern construction projects, especially steel structure factory buildings, the waterproofing problem at the junction of steel structure roofs and concrete walls has become increasingly prominent. As steel structure roofs are affected by external factors such as temperature changes, climate conditions, and wind during load-bearing and use, leakage is prone to occur at the joints between them and the walls. Traditional waterproofing structures often use fixed waterproof layers or sealing devices, which have a certain waterproofing effect, but once damaged or needing replacement, the operation is cumbersome and inconvenient. Especially in large-scale, rapidly constructed buildings such as steel structure factory buildings, the disassembly and assembly of waterproofing structures are difficult and the replacement efficiency is low, which cannot meet the requirements of modern buildings for convenient and efficient maintenance.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Reference Figures 1-3 This utility model provides an embodiment of a waterproof structure at the junction of a steel structure factory roof and a concrete wall, comprising a roof body 1, a wall body 2 fixedly connected to the lower part of the roof body 1, drainage grooves 3 evenly distributed on the upper part of the roof body 1, a slider 5 slidably connected inside the drainage groove 3 on the right side, a waterproof sleeve 4 fixedly connected to the upper part of the slider 5, the waterproof sleeve 4 slidably connected to the outside of the right side of the roof body 1, the waterproof sleeve 4 is made of rubber, the slider 5 is made of polyethylene, a waterproof component is provided on the lower left side of the waterproof sleeve 4 for waterproofing the junction of the factory roof and the concrete wall, the waterproof component includes a water-blocking arc plate 6, the water-blocking arc plate 6 is fixedly connected to the lower left side of the waterproof sleeve 4, water-blocking plates 7 are fixedly connected to the front and rear sides of the upper part of the water-blocking arc plate 6, and mounting blocks 8 are fixedly connected to the front and rear sides of the lower part of the water-blocking arc plate 6, bolts 9 are inserted inside the mounting blocks 8, and the mounting blocks 8 are fixedly connected to the wall body 2 by the bolts 9, the mounting blocks 8 are made of aluminum alloy, and the bolts 9 are made of stainless steel.
[0029] When assembling the waterproof structure at the junction of the steel structure factory roof and the concrete wall, first push the waterproof sleeve 4. Its movement causes the slider 5 to slide into the drainage channel 3. The waterproof sleeve 4 then moves the water-blocking arc plate 6, which in turn moves the mounting block 8 to the right side of the wall body 2. Next, rotate the bolt 9 to connect the mounting block 8 to the wall body 2, ensuring the waterproof structure is bonded to the wall and achieving a waterproof effect. When disassembling the waterproof structure, rotate the bolt 9 to separate it from the wall body 2. Then push the waterproof sleeve 4, causing the slider 5 to slide away from the drainage channel 3, completing the disassembly process. This simplifies the assembly and disassembly process of the waterproof structure, improves the efficiency of replacing the waterproof structure at the junction of the steel structure factory roof and the concrete wall, ensures that waterproofing treatment can be carried out quickly and conveniently, reduces maintenance costs, and improves work efficiency.
[0030] Reference Figures 1-3The water-blocking arc plate 6 has a base layer 12 inside, a waterproof layer 11 is fixedly connected to the outside of the base layer 12, and an anti-corrosion layer 10 is fixedly connected to the outside of the waterproof layer 11. The base layer 12 is made of galvanized steel plate, the waterproof layer 11 is made of EPDM rubber, and the anti-corrosion layer 10 is made of fluorocarbon coating.
[0031] By using galvanized steel sheet to ensure the load-bearing strength of the base layer 12, the structure has a stronger load-bearing capacity and can operate stably in different environments. By using EPDM rubber to improve the tensile strength and weather resistance of the waterproof layer 11, it can still maintain excellent waterproof performance under long-term exposure to various climatic conditions, preventing water penetration and structural damage. By using fluorocarbon coating material to ensure the aging resistance and acid and alkali resistance of the anti-corrosion layer 10, the service life of the material is extended, ensuring that the waterproof structure can still maintain its function and appearance in harsh environments. This greatly improves the durability and service life of the entire waterproof structure, ensuring that it can play a stable and reliable role in the long term.
[0032] Working principle: When it is necessary to assemble the waterproof structure at the junction of the steel structure factory roof and the concrete wall, push the waterproof sleeve 4 to make it slide the slider 5 into the drainage channel 3. The waterproof sleeve 4 drives the water-blocking arc plate 6 to move. The water-blocking arc plate 6 drives the mounting block 8 to slide to the right side of the wall body 2. Rotate the bolt 9 to connect the mounting block 8 to the wall body 2. When it is necessary to disassemble the waterproof structure at the junction of the steel structure factory roof and the concrete wall, rotate the bolt 9 to make it detach from the wall body 2. Push the waterproof sleeve 4 to make it slide the slider 5 away from the drainage channel 3 to complete the disassembly. This makes it easy to disassemble and assemble the waterproof structure and improves the replacement efficiency of the waterproof structure at the junction of the steel structure factory roof and the concrete wall.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
