Description

Technical Field

[0001] The utility model relates to an assembled exterior wall, in particular to a composite light-weight assembled exterior wall, and belongs to the technical field of building engineering. Background Art

[0002] The exterior wall is an important part of the building envelope. Traditional masonry exterior walls have the problems of heavy weight and single functionality. With the development of the construction industry and the changing needs, the exterior wall materials and structures are also constantly improving and updating. New exterior walls such as new material masonry structures, integrated insulation and decoration exterior walls, and composite sandwich panel exterior walls are gradually replacing traditional masonry exterior walls. Since most composite panels are finished panels assembled on site, their layered structures are fixed, which leads to poor environmental adaptability of composite panel exterior walls. For buildings with energy-saving design requirements, they often cannot meet the relevant requirements of energy saving and green buildings due to their low material thickness and unreasonable material structure. Therefore, it is necessary to improve the existing technology. Summary of the invention

[0005] The horizontal and vertical keels are both set as long straight rods with C-shaped cross-sections. The wall frame is formed by a number of horizontal keels spaced apart from top to bottom and a number of vertical keels spaced apart from left to right, which are cross-spliced ​​with each other. The wall frame is set between the upper and lower floor slabs, and is connected to the structural beams and columns corresponding to the upper and lower floor slabs by bolts and nuts so that the entire wall can be supported by the keel. The keel with a C-shaped cross-section effectively reduces its own weight while ensuring the structural strength.

[0006] A flange is provided between the bottom of the wall frame and the lower floor slab. The flange is provided as a long rectangular boss, and its length is adapted to the length of the floor slab and the length of the wall frame, so as to improve the waterproof performance of the bottom of the wall through the flange.

[0007] The insulation block is a rock wool block, which is filled in a rectangular frame surrounded by adjacent horizontal and vertical keels, so as to improve the wall insulation effect through the rock wool block.

[0008] The keel width and rock wool block thickness are set as required to meet the insulation requirements of building walls in different regions.

[0009] The fiber cement board is configured as a rectangular board, which is attached to both sides of the wall frame. Each fiber cement board is connected to a horizontal or vertical keel by a number of bolts and nuts. The fiber cement boards are sequentially spliced ​​into a whole according to the size of the wall frame, so as to ensure the wall performance through the fiber cement board's light weight, high strength, waterproof, fireproof, acid and alkali resistance and other characteristics.

[0010] The anti-corrosion and flame-retardant decorative panel is configured as a rectangular panel, which is connected to the fiber cement panel via a horizontal connecting beam, wherein the horizontal connecting beam comprises an L-shaped lower beam and an L-shaped upper beam, wherein: the vertical section of the L-shaped lower beam is connected to the inner fiber horizontal panel, the vertical section of the L-shaped upper beam is connected to the outer anti-corrosion and flame-retardant decorative panel, the horizontal section of the L-shaped lower beam and the horizontal section of the L-shaped upper beam are connected to each other via bolts and nuts, so that a cavity is formed between the fiber horizontal panel and the anti-corrosion and flame-retardant decorative panel, so as to increase the wall thickness while reducing the wall weight, and has good anti-corrosion, flame-retardant, heat-insulating, thermal-preserving and decorative effects.

[0011] A shedding piece is provided between the bottom of the anticorrosive and flame-retardant decorative board outside the fiber cement board and the lower floor slab. The top edge of the shedding piece is connected to the bottom edge of the anticorrosive and flame-retardant decorative board, and the bottom edge is connected to the lower floor slab surface, so as to improve the drainage capacity of the bottom of the wall.

[0012] The utility model has the following advantages and effects: by adopting the above scheme, the wall composed of keel, insulation block, fiber cement board and anti-corrosion flame retardant decorative board can greatly reduce the structural weight, thereby improving the overall earthquake resistance of the building, reducing the structural load, reducing the construction cost, and having excellent fireproof, waterproof and thermal insulation performance. In addition, the keel width and rock wool block thickness can be adjusted according to the location of the building, so as to ensure the thermal insulation of the wall.
