在高校科研及教学实验室建筑中,按其用途,对建筑的隔声、保湿、隔震等方面有不同的要求。除建筑设计中的常规细部作法外,在施工中住住会遇到一些新问题,需要采取特殊的施工方法。一.双道墙墙身构造:计算测试、计量中心等建筑为满足隔声、隔震、保温的要求,设计多采有夹缝空腔墙构造,即双道墙。外侧墙厚240mm,内侧墙厚120mm,两墙中间为60-120mm空气隔声层或轻质保温材料隔层。当墙体高度超过4m时,为保证砖墙砌体的整体稳定性,施工时可将内外两道墙间用240mm单砖间隔拉结砌筑,其具体作法是,沿墙体纵向及墙高方向每隔1m在两墙砌体间以搭桥方式砌一块240mm单砖,类似简化空斗墙。上下层拉结砖应间隔排列。
In the construction of scientific research and teaching laboratories in colleges and universities, according to their uses, there are different requirements for sound insulation, moisturization, and vibration isolation of buildings. In addition to the general details of the architectural design, there are some new problems in the construction and residence, and special construction methods are needed. 1. Double wall wall structure: Calculation test, measurement center and other buildings to meet the requirements of sound insulation, vibration isolation, and thermal insulation, the design uses multiple sandwich cavity wall structure, that is, double wall. The outer wall thickness is 240mm, the inner wall thickness is 120mm, and the middle of the two walls is 60-120mm air sound insulation layer or light insulation material compartment. When the wall height exceeds 4m, in order to ensure the overall stability of the brick wall masonry, during the construction, the two walls inside and outside can be masonry with 240mm single-brick intervals, the specific method is that the wall height and wall height A 240mm single brick is bridged between the two wall masonry structures every 1m to bridge the wall. The upper and lower layers should be arranged at intervals.
