[0024] Example 1

[0025] A type of reinforced concrete basement shear wall, such as Figures 1-3 As shown, the structure includes a wall, which consists of a cap beam 1, a double-layer plate, and a base 6 from top to bottom. The double-layer plate is composed of two combined plates 4 and sound insulation cotton 3 fixed between the two combined plates 4 by bolts. The shear wall structure composed of the double-layer plate and the cap beam 1 and base 6 placed on the upper and lower parts of the double-layer plate has the advantages of good sound insulation and waterproof effect, and can be replaced by imitation splicing. When the outer surface of the shear wall is damaged by cracks, impacts, etc., one layer of combined plate 4 can be chiseled off for replacement, and waterproof membrane can be laid and fixed on the outer surface, so that the surface of the new shear wall structure is restored to flatness, improving the aesthetics and structural stability.

[0026] Preferably, a waterproof layer 2, such as waterproof coating or waterproof membrane, is adhered to the outer surface of the wall; in this embodiment, it is a waterproof membrane. This effectively avoids increasing the risk of leakage in the basement due to the influence of the surrounding soil environment.

[0027] Furthermore, the combined panel 4 includes a main wall panel 401, a grid 402 fixed to one side of the main wall panel 401 by bolts, and a partition 403 fixed to one side of the grid 402 by bolts. During assembly, the main wall panel 401 is attached to the sound insulation cotton 3. During use, the grid 402 is used to separate the partition 403 and the main wall panel 401, which effectively prevents water from the external environment from seeping into the main wall panel 401 and causing damage to its materials, and also plays a certain role in sound insulation.

[0028] Preferably, the upper and lower end faces of the main wall panel 401 are provided with tenon blocks 4011 that are integral with it. The main wall panel 401 is tenoned to the bottom face of the cap beam 1 and the top face of the base 6 through the upper and lower tenon blocks 4011 respectively. During assembly, the combined plate 4 is inserted into the corresponding side of the cap beam 1 and the base 6 through the tenon blocks 4011 on it, which is convenient for installation.

[0029] More preferably, the main wall panel 401 is composed of a reinforcing cage 8 and a filling layer 7 filled inside the reinforcing cage 8, and reinforcing ribs 803 are welded to all four corners of the reinforcing cage 8; the setting of reinforcing ribs 803 can effectively improve the overall strength of the structure.

[0030] The filling layer 7 can be concrete and crack-resistant fibers;

[0031] As a supplement, the reinforcing cage 8 is composed of several frame-shaped transverse steel bars 802 and several frame-shaped longitudinal steel bars 801, and the transverse steel bars 802 and longitudinal steel bars 801 are welded in an alternating manner. The setting of the reinforcing cage 8 increases the tensile strength of the main wall panel 401. When used in conjunction with the filling layer 7 which increases the pressure of the main wall panel 401, it not only ensures the structural strength of the main wall panel 401, but also improves its structural stability.

[0032] Working principle: During assembly, the composite panel 4 is inserted into the corresponding side of the cap beam 1 and base 6 via the tenon 4011. The shear wall structure, composed of double-layer panels and cap beams 1 and bases 6 placed on the upper and lower layers of the double-layer panels, has the advantages of good sound insulation and waterproofing, and is replaceable with a simulated splicing method. When cracks or impact damage occur on the outer surface of the shear wall, a layer of composite panel 4 can be chiseled off for replacement, and waterproof membrane can be laid and fixed on the outer surface, thereby restoring the surface of the new shear wall structure to a smooth state, improving its aesthetics and structural stability.
