一种混凝土结构与ALC板连接式墙体施工技术

A Kind of Wall Construction Technology Connected Between Concrete Structure and ALC Strips

某医院工程地下室外墙和人防区域内墙采用钢筋混凝土墙体,电梯井道内隔墙采用蒸压加气混凝土砌块砌筑,其余部位室内内隔墙均采用ALC蒸压加气混凝土条板,不同材质墙体在热膨胀、结构受力上具有较大差异,长期使用后极易导致墙体在接缝处脱开,使墙面产生缝隙,同时易在潮湿环境中渗水导致墙皮脱落等问题。采用不同材质墙体连接技术,可以提高2种不同材质结构的整体抗震性能,增强墙面一体性和整体性,有效地解决了不同材质墙体连接处因产生裂缝而导致墙面天然石粉抹灰出现空鼓、开裂、脱落等缺陷问题,为以后类似工程中的不同材质墙体连接积累了经验,具有一定的推广性和可行性。

Reinforced concrete walls are used for the outer wall of the basement and the inner wall of the civil air defense area of a hospital project, autoclaved aerated concrete blocks are used for the internal partition wall of the elevator shaft, and ALC autoclaved aerated concrete strips are used for the indoor partition walls in other parts.Walls of different materials have great differences in thermal expansion and structural stress. After long-term use, it is very easy to cause the wall to detach at the joints, causing cracks in the wall, and it is easy to seep water in the wet environment, causing the wall skin to fall off and other problems. The use of wall connection technology with different materials can improve the overall seismic performance of two different material structures and enhance the integrity and integrity of the wall. It effectively solves the problems of hollowing, cracking, falling off and other defects of natural stone powder plastering on the wall surface caused by cracks at the connection of walls with different materials, and accumulates experience for the connection of walls with different materials in similar projects in the future, which has certain popularization and feasibility.
