建筑施工中正在砌筑或已经砌筑好的墙体,在尚未安装楼板或屋面时遇到大风的情况下,如果不及时采取必要的加固措施(如加临时支撑),将有被风吹倒的可能。这类事故特别在沿海地区发生较多。因此,根据风力的大小,对墙体的自由高度作出具体规定,是保证施工安全必不可少的一项技术措施。《砌体工程施工及验收规范》GBJ14—66(修订本)第12条规定:“对尚未安装楼板或屋面的墙体,当可能遇大风时,应根据风力和墙的高度、长度、宽度、部位及容重等因素,采取支撑等措施,以保证其稳定性”。在施工中执行这一规定显然有一定的
In the construction of a wall that is being built or has been masonry, if a strong wind is encountered when the floor or roof has not been installed, if the necessary reinforcement measures (such as temporary support) are not taken in time, there will be wind blowing down. Possible. This type of accident has occurred especially in coastal areas. Therefore, according to the size of the wind, the specific provisions for the free height of the wall are an indispensable technical measure to ensure the safety of the construction. Regulation 12 of the “Code for Construction and Acceptance of Masonry Projects” GBJ14-66 (Revised) stipulates: “For walls that have not yet been installed with slabs or roofs, they should be based on the height, length, width, and height of wind and walls when high winds may be encountered. The factors such as the parts and the bulk density shall be taken to support their stability." The implementation of this provision in construction is obviously certain
