Construction method of externally-wrapped multi-cavity steel plate concrete composite shear wall
The invention provides a construction method of an externally-wrapped multi-cavity steel plate concrete composite shear wall, and belongs to the technical field of steel structure building construction. The construction method comprises the following steps that 1, the externally-wrapped multi-cavity steel plate concrete composite shear wall is constructed; 2, the top of the shear wall is covered with a top steel plate, and the top steel plate and the top of the shear wall are sealed; 3, a vacuumizing device is adopted for pumping air in the steel plate and the shear wall, and the vacuumizing state is kept for at least preset time; 4, the vacuumizing device is closed and moved away, the top steel plate is opened, and laitance on the surface of concrete in the shear wall is removed; and 5, the steps 1 to 4 are repeated according to a preset construction scheme. According to the construction method, the closed space formed by combining the shear wall and the top steel plate is vacuumizedthrough the vacuumizing device, so that the pressure in the shear wall is reduced, bubbles in concrete in the shear wall are slowly moved upwards out of the concrete surface, the concrete is filled more fully, the compactness of the concrete is guaranteed, and the void rate of the steel-concrete joint surface is reduced.
本申请提供一种外包多腔钢板混凝土组合剪力墙施工方法，属于钢结构建筑施工技术领域。包括：步骤一，施工外包多腔钢板混凝土组合剪力墙；步骤二，在剪力墙顶部覆盖顶钢板，使顶钢板与剪力墙顶部密封设置；步骤三，采用抽真空装置抽取钢板与剪力墙内的空气，并保持抽真空状态至少预设时间；步骤四，关闭并移走抽真空装置，打开顶钢板，清理剪力墙内混凝土表面浮浆；步骤五，根据预设构建方案，重复操作步骤一至步骤四。该方法通过利用抽真空装置，对剪力墙和顶钢板组合成的密闭空间进行抽真空操作，使得剪力墙内的压强降低，从而使得剪力墙内混凝土中的气泡缓慢上移出混凝土面，混凝土填充更加充实，保证混凝土密实度，降低钢混结合面的脱空率。
