    首先,先剖析一下楼承板厂家偷工减料的几种状况
    Firstly, the paper analyses the situation of jerry-building and material reduction in floor support plate manufacturers.
    一种状况就是:厚度减薄,这是楼承板厂家明目张胆的偷工减料。诸如用0.8mm厚度钢板冒充1.0mm厚度钢板;
    The first condition is that the thickness is thinned, which is the blatant jerry-building material reduction of floor deck manufacturers. Such as using 0.8mm thickness steel plate as 1.0mm thickness steel plate;
    第二种状况就是:屈从强度和镀锌量作假,这个是楼承板厂家比拟荫蔽的偷工减料比方,采购方请求选用410Mpa的强度,楼承板厂家仅用345 Mpa强度资料或者235Mpa的;而或用180g/m2镀锌量,而仅仅用60g/m2镀锌量;
    The second situation is that the yield strength and galvanizing quantity are falsified. This is the stolen material reduction analogy of the floor deck manufacturer. The purchaser requests to select 410 Mpa strength. The floor deck manufacturer only uses 345 Mpa strength information or 235 Mpa strength information, or uses 180 g/m2 galvanizing quantity instead of 60 g/m2 galvanizing quantity.
    第三种状况就是:资料的进料宽度减少,比方进料宽度为1250mm,而更后成型为720mm宽,而有些不良楼承板厂家进料宽度为1190mm,更后成型也为720mm宽,谁不知断面性质降低了不少。

    The third situation is that the width of material feeding is reduced, for example, the width of material feeding is 1250 mm, while the width of final forming is 720 mm, while the width of material feeding is 1190 mm for some poor floor bearing plate manufacturers, and the width of final forming is 720 mm. Who knows that the nature of cross-section has been reduced a lot.

    关于一种状况,一是用游标卡尺来卡,但由于原本厚度比拟薄,可能会呈现误差,所以另一个方法就是称重。很简单,从楼承板的上面割一米长的样本,用比拟精准的用具停止称重,依照M=ρv的公式,求出V,然后求出厚度,那么能否厚度减薄了如指掌。
    As for the first situation, one is to use vernier calipers to calibrate, but because the original thickness is comparatively thin, there may be errors, so the other method is weighing. Simply cut a meter-long sample from the top of the floor deck, stop weighing with a comparatively accurate tool, according to the formula of M = P v, get the V, and then calculate the thickness, then whether the thickness can be reduced like the palm of your hand.
    针对第二种状况,只能采用第三方检测的办法来处理,普通7个工作日就出结果了。
    In view of the second situation, only the third-party detection method can be used to deal with it, and the results will come out in 7 working days.
    第三种状况,用货单位能够把现场供货的尺寸与标准图集的详细尺寸对照,假如发现尺寸不对便为压型钢板厂家偷工减料。
    In the third case, the supplier can compare the size of the on-site supply with the detailed size of the standard atlas. If the size is found to be incorrect, it will be jerry-built by the profiled steel plate manufacturer.
