目前,在一些中小型工程施工中,未在现场设置养护室,而是自制一些养护箱或水池,用普通温度计测定水温,用加减冷水或温水的方法调节水温,这种养护试块的方法很不可靠。为解决中小型建筑工地混凝土试块的标准养护问题,我们采用河北省冀县起重运输机械厂的HWS-2型混凝土试块养护箱等一系列产品。HWS—2型混凝土试块养护箱功率2kW,电源电压AC220V。可容纳15cm见方的试块24组72块,可调温度范围10℃～80℃,控制湿度范围RH90%以上,外形尺寸820×780×1700mm,对中小型建筑工地,可用养护箱代替试块标养室。养护箱搬运灵活,可重复使用,从长远看可
At present, during the construction of some small and medium-sized projects, instead of setting up a curing room on site, some conservation boxes or pools are made by ourselves. The water temperature is measured by an ordinary thermometer, and the water temperature is adjusted by adding or subtracting cold or warm water. This method of conserving test blocks Very unreliable. In order to solve the problem of standard maintenance of concrete blocks in small and medium-sized construction sites, we adopted a series of products such as the HWS-2 concrete block retaining box and the lifting and transportation machinery plant in Hebei Province. HWS-2 concrete block maintenance box power 2kW, power supply voltage AC220V. Accommodates 24 groups of 72 blocks of 15cm square, with an adjustable temperature range of 10°C to 80°C, a control humidity range of RH90% or more, and an external dimension of 820×780×1700mm. For small and medium-sized construction sites, a maintenance box can be used in place of the test blocks. Support room. The conservation box is flexible to handle and can be reused. It can be used in the long term.
