Description
Technical Field
[0001] This utility model relates to the field of rammed earth wall technology, and in particular to an improved structure for reinforcing the corners of rammed earth walls with stone. Background Technology
[0002] Rammed earth walls, as a building material with a long history and cultural value, are widely used in traditional and rural architecture due to their advantages such as environmental protection, energy saving, and low cost. In particular, rammed earth walls are regarded as a natural and sustainable building method in some ecological buildings and cultural heritage protection. However, with the development of modern building technology and the improvement of building standards, traditional rammed earth walls have revealed some shortcomings, especially in terms of structural stability, erosion resistance, aesthetics, and construction efficiency, and can no longer fully meet the needs of modern buildings.
[0003] shortcomings of traditional rammed earth walls
[0004] 1. Insufficient tie strength:
[0005] Traditional rammed earth walls are prone to cracking due to weak bonding between internal materials, especially at corners where insufficient tension makes the wall connections weak.
[0006] 2. Poor resistance to erosion:
[0007] Rammed earth walls are not very resistant to moisture and external natural factors. When exposed to rainwater, snowmelt and other environments for a long time, they are prone to peeling, weathering or delamination, especially at corners, where they are easily subjected to greater impact and erosion.
[0008] 3. Poor aesthetic appearance:
[0009] Traditional rammed earth walls are usually untreated, with rough surfaces and monotonous colors, which cannot meet the high requirements of modern architecture for aesthetics and decoration. Moreover, they are easily damaged when exposed to the outside world for a long time, affecting the overall image of the building.
[0010] 4. Low construction efficiency and difficulty in quality control:
[0011] Traditional construction methods rely on manual compaction, lack standardized and mechanized construction tools, have long construction cycles, and make it difficult to control the quality consistently. Uneven compaction or uneven stress can easily occur during the construction process.
[0012] Therefore, it is essential to invent a method for reinforcing the corners of rammed earth walls with stone materials to improve the structure. Utility Model Content
[0013] To address the aforementioned technical problems, this utility model provides an improved stone-reinforced corner structure for rammed earth walls, solving the issues of insufficient tensile strength, poor erosion resistance, poor aesthetics, low construction efficiency, and difficulty in quality control inherent in existing structures. The improved stone-reinforced corner structure for rammed earth walls includes a rammed earth wall, an attached mesh, an adhesive concrete layer, a protective base block, an attachment layer, and decorative rubble. The attached mesh is fixedly installed on the surface of the rammed earth wall, and the adhesive concrete layer is applied to the surface of the attached mesh. The protective base block is bonded to the surface of the adhesive concrete layer and connected and fixed to the rammed earth wall. The attachment layer is applied to the surface of the protective base block, and the decorative rubble is bonded to the surface of the attachment layer.
[0014] The protective base block includes a base slab, a stud groove, a rotating end, tie bars, and installation tools. The base slab protective base block is bonded to the surface of the bonded concrete layer, and the stud groove is opened on the surface of the base slab. The rotating end is fixedly installed at one end of the tie bar. The tie bar passes through the stud groove and is driven into the interior of the rammed earth wall by rotating the rotating end with the installation tools.
[0015] Decorative rubble includes a slab substrate, a bottom roughened layer, and a surface decorative layer. The bottom roughened layer is located at the bottom of the slab substrate and is bonded to the surface of the attachment layer. The surface decorative layer is located on the surface of the slab substrate.
[0016] The protective base layer blocks include two shapes: straight plates and "L"-shaped plates. The straight plates are installed on the flat surface of the rammed earth wall, while the "L"-shaped plates are installed at the corners of the rammed earth wall. The depth of the stud groove is consistent with the thickness of the rotating end, and the surface of the reinforcing bars is threaded, connecting the protective base layer blocks to the rammed earth wall through rotation. An adhesive layer is applied to the surface and joints of the protective base layer blocks, serving the following functions: ① Enhancing structural stability: Through the bonding between the base plate and the rammed earth wall, the protective base layer blocks strengthen the structural integrity of the wall surface and corners. ① It provides a solid foundation, preventing the wall from cracking or falling off under stress or environmental changes; ② It enhances erosion resistance: The protective base layer is particularly suitable for corner areas of rammed earth walls. The "L"-shaped plate design provides additional protection in these key areas, significantly improving the wall's resistance to rain and snow erosion; ③ It facilitates construction and installation: The protective base layer includes studs, rotating ends, and tie rods. Combined with installation tools, it can be quickly fixed, making construction convenient and efficient; ④ It serves as an intermediate support layer: Located between the bonded concrete layer and the attachment layer, the protective base layer acts as a load-bearing and connecting intermediate layer, providing a stable foundation for the installation of decorative rubble.
[0017] Decorative rubble includes two shapes: straight slabs and "L"-shaped slabs. The straight slabs are installed on the flat surface of the rammed earth wall, while the "L"-shaped slabs are installed at the corners. The rubble stones are interlocked. The bottom roughened layer is treated to remove imperfections. The surface decorative layer can be finished with textures such as bush-hammered, pineapple, or flamed finishes. This process serves several purposes: ① It improves the wall's resistance to environmental erosion: As an outer covering material, the decorative rubble effectively resists wind, rain, frost, and other external natural factors, extending the service life of the rammed earth wall. The roughened bottom layer enhances adhesion to the outer layer, preventing the rubble stones from falling off and maintaining long-term stability. ② Enhance the aesthetic appearance of the wall: The surface of the decorative rubble stone is treated to present various textures such as lychee, pineapple, and flamed, improving the overall visual effect and texture of the building. Different texture designs can adapt to various style requirements, suitable for both traditional buildings and modern designs; ③ Enhance the overall structural strength: The decorative rubble stone, in the form of straight slabs and "L"-shaped slabs, is tightly integrated with the plane and corner parts of the rammed earth wall, and is interlocked with each other, which not only provides a decorative effect, but also improves the structural strength and shear resistance; ④ Serves as an impact barrier: The decorative rubble stone covers the protective base block and the attachment layer, forming an external hard barrier that can effectively absorb and disperse physical impacts from the outside, protecting the internal rammed earth wall.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. The protective base block of this utility model has the following functions: ① Enhancing structural stability:
[0020] The protective base layer blocks, through the bonding between the base slab and the rammed earth wall, enhance the structural stability of the wall surface and corners, preventing cracking or detachment under stress or environmental changes; ② Improve erosion resistance: The protective base layer blocks are particularly suitable for corner areas of rammed earth walls. The "L"-shaped design provides additional protection in these critical areas, significantly improving the wall's resistance to rain and snow erosion; ③ Facilitate construction and installation: The protective base layer blocks include studs, rotating ends, and tie rods, which, combined with installation tools, allow for rapid fixing, making construction convenient and efficient; ④ Serv as an intermediate support layer: Located between the bonded concrete layer and the attachment layer, the protective base layer blocks act as a load-bearing and connecting intermediate layer, providing a stable foundation for the installation of decorative rubble.
[0021] 2. The decorative rubble of this utility model has the following functions: ① Improves the wall's resistance to environmental erosion: As an outer covering material, the decorative rubble can effectively resist the erosion of the wall by wind, rain, frost, and other external natural factors, extending the service life of the rammed earth wall. The roughening treatment of the bottom roughened layer enhances the adhesion with the attached layer, preventing the decorative rubble from falling off and maintaining long-term stability; ② Enhances the wall's aesthetic appearance: The surface of the decorative rubble, after treatment, can present various textures such as lychee surface, pineapple surface, and flamed surface, improving the overall visual effect and texture of the building. Different texture designs can adapt to various style requirements, suitable for both traditional buildings and modern designs; ③ Enhances the overall structural strength: The decorative rubble, in the form of straight plates and "L"-shaped plates, is tightly integrated with the plane and corner parts of the rammed earth wall, interlocking and splicing with each other, not only providing a decorative effect but also improving the structural strength and shear resistance; ④ Serves as an impact barrier: The decorative rubble, covering the protective base block and the attached layer, forms an external hard barrier that can effectively absorb and disperse physical impacts from the outside, protecting the internal rammed earth wall.
