摘　　要：针对房建项目整体施工质量难以检测的问题,研究基于物联网的房建项目试验检测方法。基于物联网技术中的无线传感技术,经由移动设备的摄像头、北斗卫星导航系统(BDS)实时采集现场检测数据,进行建筑保温性能、抗压强度、抗震性能的检测。结果表明:挂板饰面外墙的保温效果最优;混凝土养护龄期时间越长,其抗压强度与弹性模量的变异系数越小,说明龄期延长,外界对混凝土的影响不断降低;在龄期一致时,标准条件养护试件的强度值与弹性模量均大于相同条件养护试件,标准条件养护试件的变异性较小,说明其受环境影响较小;在不同地震波时,框-剪结构的加速度响应幅度均显著高于框-剪抗震结构,框-剪结构的最大加速度分别是1180 cm/s^(2)、1400 cm/s^(2)、500 cm/s^(2);框-剪抗震结构的最大加速度均是34.9 cm/s^(2),隔震结构可降低结构加速度响应,延长其使用期限。Aiming at the problem that the overall construction quality of housing construction project is difficult to detect,the test and detection method of housing construction project based on Internet of things is studied.Based on the wireless sensing technology in the Internet of things technology,through the camera of the mobile device,BeiDou Navigation Satellit System,real-time on-site detection data is collected to detect the building's thermal insulation performance,compressive strength and seismic performance.The test and analysis results show that the thermal insulation effect of hanging plate facing exterior wall is the best.The longer the concrete curing age,the smaller the variation coefficient of compressive strength and elastic modulus,indicating that the age is prolonged and the external influence on concrete is decreasing.When the age is the same,the strength value and elastic modulus of the specimens cured under standard conditions are greater than those cured under the same conditions,and the variability of the specimens cured under standard conditions is small,indicating that they are less affected by the environment.Under different seismic waves,the acceleration response amplitude of frame shear structure is significantly higher than that of frame shear structure.The maximum accelerations of frame shear structure are 1180,1400 and 500 cm/s^(2) respectively.The maximum acceleration of frame shear wall seismic structures is 34.9 cm/s^(2).The isolated structure can reduce the acceleration response of the structure and prolong its service life.
