Description

Technical Field

[0001] The utility model relates to the technical field of house waterproof structures, in particular to a waterproof reinforcement structure for old houses. Background Art

[0002] Over time, a large number of old houses face various problems. Due to their age, their construction structures and materials often have limitations. Over time, these houses are exposed to the erosion of the natural environment and the impact of human factors, and their performance gradually deteriorates.

[0003] Waterproofing and reinforcement are crucial for the maintenance of older buildings. Traditional waterproofing and reinforcement methods typically involve simply laying waterproofing membranes or applying waterproof coatings to the roof surface. However, these traditional waterproofing and reinforcement methods have numerous drawbacks.

[0004] The main drawbacks of traditional waterproof reinforcement structures are as follows: First, their waterproofing effectiveness is limited, and they are prone to leakage over time. This is because traditional waterproof membranes and coatings can degrade over time due to material aging, poor construction quality, or damage from external forces. Second, traditional structures offer poor reinforcement and are unable to effectively address structural deformation and cracking. Older homes can experience structural deformation and cracking over time due to factors such as foundation settlement and temperature fluctuations, making it difficult to effectively reinforce and repair these with traditional waterproof reinforcement structures. Furthermore, traditional structures lack thermal insulation and are unable to meet the energy-saving requirements of modern buildings. Older homes often suffer from poor insulation, which can lead to heat loss in the winter and increased exposure to high temperatures in the summer, increasing energy consumption.

[0029] The working principle of the waterproof reinforcement structure for old houses of this utility model is as follows: through the synergistic effect of the multi-layer structure, waterproofing, reinforcement and thermal insulation of old houses are achieved. The waterproof primer layer enhances the adhesion of the subsequent waterproof layer and provides preliminary waterproofing; the waterproof membrane layer forms a continuous waterproof layer to block water penetration; the waterproof coating layer fills the tiny gaps to further improve the waterproof performance. The reinforcement grid layer improves the strength and crack resistance of the overall structure to cope with possible structural deformation and cracks in the house. The thermal insulation layer reduces the energy consumption of the house and improves indoor comfort. The protective layer protects the waterproof layer and the reinforcement layer from external damage, while the finishing layer plays a role in aesthetics and protection.

[0030] The functions of each layered structure of the utility model are as follows:

[0031] 1. Roof base 1: Serves as the foundation of the entire waterproof reinforcement structure and provides support for other layers of the structure.

[0032] 2. Waterproof primer layer 2: Use acrylic waterproof primer with a thickness of 0.5-1mm. Its function is to penetrate into the roof base surface, enhance the adhesion of the subsequent waterproof layer to the base surface, and at the same time provide a preliminary waterproofing effect, preventing water from penetrating the base surface.

[0033] 3. Waterproofing membrane layer 3: Use SBS modified asphalt waterproofing membrane with a thickness of 3-5mm. Use hot melt or cold bonding method to construct the membrane. The membranes are firmly overlapped to form a continuous waterproof layer, effectively preventing large-scale water penetration.

[0034] 4. Waterproof coating layer 4: This is a polyurethane waterproof coating with a thickness of 1.5-2mm. This layer of coating fills any small gaps in the waterproof membrane, further enhancing the waterproof performance and preventing moisture from penetrating the interior of the house.

[0035] 5. Reinforcement Mesh Layer 5: Made of glass fiber mesh with a mesh size of 5mm x 5mm. It is fixed to the waterproof coating layer with an adhesive to enhance the overall structural strength and crack resistance, preventing cracks in the house due to structural deformation or external forces.

[0036] 6. Thermal insulation layer 6: Use extruded polystyrene board with a thickness of 50-60mm. This layer of material has excellent thermal insulation properties, which can effectively reduce the energy consumption of the house, reduce indoor heat loss in winter, and block the external high temperature in summer.

[0037] 7. Protective layer 7: Made of C20 fine stone concrete with a thickness of 40-50mm. Its function is to protect the waterproof and heat-insulating layer and the reinforcement layer from external damage, such as mechanical collision.

[0038] 8. Finishing layer 8: ceramic tiles are used. Not only are they beautiful, but they also further protect the entire waterproof reinforcement structure and extend its service life.

[0039] The construction steps of this utility model are as follows:

[0040] 1. Base treatment: Clean the roof surface of old houses, removing loose parts, dust, and debris to ensure a flat and solid surface. Use a broom, shovel, or other tools for cleaning. For stubborn stains, use detergent. Repair any cracks and potholes in the surface, using materials such as cement mortar to ensure a flat surface.

[0041] 2. Apply waterproof primer: Mix the acrylic waterproof primer evenly and apply it evenly to the roof surface using a roller brush or spray gun, ensuring the primer layer is 0.5-1mm thick. Allow the primer to dry, which generally takes about 24 hours, depending on the ambient temperature and humidity.

[0042] 3. Lay the waterproofing membrane: Prepare the SBS modified asphalt waterproofing membrane and cut it to fit the roof area. Apply the membrane using either the hot melt or cold gluing method. The hot melt method uses a spray gun to heat the bottom surface of the membrane to securely bond it to the base surface; the cold gluing method uses a specialized adhesive to adhere the membrane to the base surface. Ensure the overlap between the membranes is at least 100mm, and the joints are tightly sealed.

[0043] 4. Apply waterproof coating: Stir the polyurethane waterproof coating evenly and apply it evenly to the waterproof membrane using a roller brush or spray gun, ensuring a thickness of 1.5-2mm. Wait for the waterproof coating to dry, which usually takes about 24 hours.

[0044] 5. Lay the reinforcement mesh layer: Prepare the fiberglass mesh and cut it into the appropriate size. Use adhesive to stick the mesh to the waterproof coating layer, making sure the mesh is flat, wrinkle-free, and firmly bonded.

[0045] 6. Lay the insulation layer: Prepare the extruded polystyrene board and cut it according to the roof area. Lay the extruded polystyrene board on the reinforcement grid layer and fix it with fixings to ensure the insulation layer is flat and firm.

[0046] 7. Pour the protective layer: Prepare C20 fine aggregate concrete and mix it according to the specified mix ratio. Pour the fine aggregate concrete onto the thermal insulation layer and vibrate it with a flat vibrator to ensure the concrete is dense. Smooth the concrete surface to ensure the protective layer thickness reaches 40-50mm.

[0047] 8. Lay the finishing layer: Select appropriate tiles and lay them out according to the design requirements. Use tile adhesive to attach the tiles to the protective layer, ensuring the tiles are flat and secure, with even gaps. Fill the gaps between the tiles with a dedicated grout to ensure a beautiful finish.

[0048] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
