本文介绍美国一种如何对砌体砌筑施工的施工工效进行预估的方法。引入“人.天”的概念,将砌筑过程中的每一项任务转化为所需的“人.天”数;用图表方式给出不同厚度和重量的标准尺寸混凝土空心砌块砌体的砌筑工效数值。对影响砌筑工效的各种因素,包括块型、砌筑灰缝形式,等等,则引入用百分数表示的时间损失率来加以调整。使用此方法,使砌块砌体砌筑工效的预估和施工进度管理,变得非常容易并可以量化。
This article describes how to estimate the work efficiency of masonry construction in the United States. The introduction of the concept of “people. Days”, the masonry process of each task into the required number of “people. Days” number; given the different thickness and weight of the standard size concrete hollow masonry Masonry masonry work efficiency numerical. Various factors that affect the efficiency of masonry, including block, masonry, and so on, are introduced by adjusting the percentage of time lost. Using this method, it is easy and quantifiable to make estimates of blockwork efficiency and schedule management of block masonry.
