摘要
目的根据现浇混凝土模板侧压力试验结果,对现行模板规范中的侧压力计算公式进行验证,为实际工程模板搭设提供可靠的计算依据.方法采用高精度振弦式压力盒对现场浇筑混凝土柱和剪力墙进行压力监测,通过对实测数据分析,验证现行模板规范公式的适用性.结果部分监测点的最大压力值超过模板规范系数影响公式计算值,模板规范液体压强公式计算值与监测点最大压力值较接近.结论按目前模板规范给出的计算公式进行模板支撑的搭设,规范系数影响公式计算结果与实际侧压力值相差较大.采用液体压强公式进行工程模板压力计算偏于安全.
According to the results of cast-in-place concrete formwork lateral pressure test, to verify the formula for calculating the side pressure in the current template specification, to provide reliable calculation basis for the actual project template erection. The methods employed is high precision vibrating string pressure box for pressure monitoring of concrete column and shear wall, Through the analysis of the measured data, the applicability of the current template specification formula will be verified. The result is that the maximum pressure value of some monitoring points exceed the formula calculation value of template specification coefficient, the calculation value of the liquid pressure formula according to the template specification is close to the maximum pressure value of the monitoring points. According to the calculation formula given by the current template specification to carry out the erection of formwork support, The formula calculation results of the formula coefficient influence is difference from the actual side pressure value. Using the liquid pressure formula to calculate the pressure of the project template is safe.
