Description

Technical Field

[0001] The utility model relates to the technical field of decoration keels, and more particularly to a nearly zero-energy-consumption assembled exterior protective wall vertical keel structure. Background Art

[0002] The exterior wall structure of a building typically consists of the following layers, which may vary depending on design requirements and building standards: Load-bearing walls (or non-load-bearing walls): These are the core structural components of the exterior wall, responsible for bearing the weight of the building or serving as partitions. Common materials include bricks, concrete blocks, or reinforced concrete slabs. Load-bearing walls primarily provide support and structural stability. Insulation: This layer improves the building's thermal insulation and reduces heat exchange between indoors and outdoors. Common insulation materials include polystyrene foam (EPS), extruded polystyrene (XPS), rock wool, and glass wool. The thickness and type of insulation are typically determined by the building's location and climate. Waterproofing: This prevents rainwater and moisture from penetrating the wall. Waterproofing typically utilizes materials such as waterproof coatings, asphalt-based membranes, or waterproof membranes, and is particularly important in rainy or humid environments. Decorative layer (exterior finish): This is the outermost layer of the exterior wall, providing both decorative and protective functions. Common decorative materials include exterior wall paint, tiles, stone, and glass curtain walls. Beyond aesthetics, it also further enhances a building's weatherproofing, UV resistance, and other capabilities. Air layer (optional): In some building structures, an air layer is left between the insulation and the load-bearing walls. This design further enhances thermal insulation while reducing the effects of moisture on the walls. The combination of these layers not only improves the building's durability but also effectively provides insulation, soundproofing, and waterproofing, ensuring comfortable use and energy efficiency.

[0003] However, existing keel structures or walls have some common shortcomings:

[0004] 1. Insufficient sound insulation performance. Due to the single material, the traditional keel wall structure usually cannot effectively soundproof and easily causes indoor and outdoor noise interference, especially in high-noise areas.

[0005] 2. Poor thermal insulation performance and high energy consumption. Many existing wall structures use single insulation materials with limited thermal insulation effects, which easily lead to high energy consumption. Especially in cold or hot climates, indoor temperature regulation becomes more difficult and energy consumption increases significantly.

[0006] 3. Traditional wall materials with poor fire resistance, such as wooden keels or ordinary insulation materials, may not be resistant to high temperatures in a fire and are easy to burn, posing a major fire hazard.

[0007] 4. Poor weather resistance and deformation resistance. Many existing wall structures are easily deformed or damaged under adverse weather conditions (such as strong winds and heavy rains). They lack long-term weather resistance, especially the exterior finishing materials are prone to falling off.

[0008] 5. The exterior finish has poor stability. Traditional walls often use a single paint or veneer tiles for exterior finishes, which are prone to cracking or falling off due to factors such as thermal expansion and contraction, affecting the appearance and durability of the building. Utility Model Content

[0009] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a nearly zero-energy-consumption assembled exterior retaining wall vertical keel structure.

[0010] To achieve the above-mentioned objectives, the present invention provides the following technical solutions, which mainly include: a nearly zero-energy assembled exterior retaining wall vertical keel structure, which is arranged on the outside of the main wall and fixed by expansion bolts or embedded parts. The keel structure includes vertical keels arranged longitudinally and horizontal keels arranged transversely. The vertical keels and the horizontal keels are arranged in a staggered manner, and sound insulation boards and sound insulation felts are installed between adjacent keels. A composite insulation layer is arranged near the outer surface of the main wall, and a rock wool board, a cement board, a steel plate fish scale mesh, a steel wire mesh and a cement mortar layer are arranged on the outer surface of the keel structure from the inside to the outside.

[0011] Preferably, the vertical keels and the horizontal keels are arranged to penetrate and cross each other, and the vertical and horizontal spacings of the keels are between 400-600 mm.

[0012] Preferably, the vertical keel and the horizontal keel are either light steel keel or aluminum alloy keel.

[0013] Preferably, the composite insulation layer is made of multiple layers of insulation materials, and the insulation materials include one or more of mineral wool, foam glass, polystyrene foam board, and polyurethane foam. The outermost layer of the composite insulation layer is a fireproof material layer.

[0014] Preferably, polystyrene foam boards or extruded polystyrene boards are further provided on both sides of the rock wool board to clamp the rock wool board in the middle.

[0015] Preferably, an air layer is provided between the rock wool board and the cement board, and the thickness of the air layer is 20-50 mm.

[0016] Preferably, a steel plate fish scale mesh is provided on the outside of the cement board. The steel plate fish scale mesh is a welded structure with a plurality of rectangular holes on the surface. The hole diameter is 200-250 mm. The rectangular holes are interconnected and a spine connecting strip is provided in the middle.

[0017] Preferably, a steel wire mesh is provided on the outside of the steel plate fish scale mesh, and the steel wire mesh and the steel plate fish scale mesh are bound together by iron wire, with a binding spacing of 300-400mm.

[0018] The beneficial effects are as follows: The composite insulation layer uses multiple layers of insulation materials (mineral wool, foam glass, polystyrene foam board, polyurethane foam, etc.) to ensure the efficient thermal insulation performance of the wall, helping to reduce energy consumption and meet the requirements of near-zero-energy buildings. The outer layer of the insulation material is fireproof, further enhancing the safety of the wall, especially in the event of a fire, and providing better fire protection. Rock wool board, as the main insulation material, has excellent thermal insulation and fireproof properties. At the same time, polystyrene foam board is installed on both sides to further enhance the thermal insulation effect of the wall, reduce thermal bridges, and achieve better energy savings. Steel plate fish scale mesh and steel wire mesh provide a solid external decorative support, allowing the surface to be further coated with cement mortar, thus achieving a beautiful exterior wall effect. This design ensures the wall's strength while also allowing for personalized exterior wall decoration according to design requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1:

[0026] A near-zero-energy prefabricated exterior wall vertical purlin structure is installed outside the main wall and secured to the main wall using expansion bolts or embedded components. The purlin structure comprises vertical purlins 2 arranged longitudinally and transverse purlins 1 arranged transversely, staggered at 400mm intervals. Sound insulation panels are installed between adjacent purlins, and soundproofing felt is applied to the panels to enhance the wall's soundproofing performance.

[0027] On the outer surface close to the main wall, a composite insulation layer 3 is provided. The composite insulation layer 3 includes a composite material combination of mineral wool and foam glass, and the outermost layer is a fireproof material layer. The outer surface of the composite insulation layer 3 is sequentially installed with a rock wool board 4, a cement board 5, a steel plate fish scale mesh 6, a steel wire mesh 7 and a cement mortar layer 8. Among them, the aperture of the steel plate fish scale mesh 6 is 200mm, and a number of rectangular holes are formed by welding on the surface. The steel plate fish scale mesh 6 and the outer steel wire mesh 7 are tied together with iron wire at a spacing of 300mm. The combination of the steel plate fish scale mesh 6 and the steel wire mesh 7 effectively enhances the overall strength and impact resistance of the wall, while providing adhesion to the exterior wall to facilitate the subsequent construction of the cement mortar layer.

[0028] This structure can effectively improve the thermal insulation and sound insulation effects of the building through the composite insulation layer 6, multi-layer sound insulation materials and a strong keel support system. It is suitable for buildings in noise-sensitive areas and meets the energy-saving requirements of near-zero energy buildings.

[0029] Example 2:

[0030] Based on Example 1, the keel structure and insulation material selection were further optimized. The vertical keels 2 and horizontal keels 1 are constructed of aluminum alloy, offering improved corrosion resistance and lightweight properties, making them suitable for high-humidity environments and construction projects with weight constraints. The spacing between the vertical and horizontal keels is set at 600 mm to accommodate larger exterior wall panels.

[0031] The design of the composite insulation layer 3 uses a combination of polystyrene foam and polyurethane foam, further enhancing the wall's thermal insulation. The polystyrene foam panels are placed on either side of the rock wool board 4, sandwiching it between them. This effectively prevents heat loss and improves the overall stability of the insulation layer.

[0032] Furthermore, a 30mm air layer is provided between the rock wool board 4 and the cement board 5 to enhance the wall's ventilation, prevent condensation accumulation caused by temperature fluctuations, and extend the wall's service life. The 250mm-diameter steel scale mesh 6 on the outside of the cement board 5, combined with the wire-bound steel mesh 7, further enhances the wall's fire resistance and durability. This wall structure is suitable for cold climates, effectively controlling the temperature difference between indoors and outdoors, and ensuring energy savings.

[0033] Example 3:

[0034] This prefabricated exterior wall structure, suitable for high-rise buildings, utilizes lightweight steel keels. Vertical keels (2) and horizontal keels (1) intersect and intersect with each other, spaced 500 mm apart. The keels are secured to the exterior of the high-rise building's main structure with expansion bolts, providing high wind pressure resistance. To further enhance the wall's sound insulation, sound insulation panels and felt are installed between adjacent keels. The panels utilize a double-layer design, with the felt laid between the two layers of panels.

[0035] The composite insulation layer 3 is made of polyurethane foam and foam glass, with an outer layer of fire-resistant material to ensure wall stability in high-temperature environments. Rock wool panels 4, cement boards 5, and an exterior finish system are sequentially installed on the exterior surface of the composite insulation layer 3. The exterior finish system uses dry-hanging stone, which is fixed to the cement boards via a point-type connection system, ensuring that the high-rise building's exterior finish can withstand strong winds, rain, and snow.

[0036] A 50mm-thick air layer is designed between the cement board 5 and the rock wool board 4 to enhance thermal and sound insulation and prevent moisture from affecting the insulation layer. By optimizing the keel layout and material selection, this structure meets the high fire protection, sound insulation, and energy conservation requirements of high-rise buildings while ensuring the safety and aesthetics of the exterior wall.
