《健筑工人》1998年第3期刊登了《预制钢筋砖过梁的施工》(以下简称《预》文)一文,我们认为此法不可取,也不宜推广,理由如下。1.浪费材料,增加工程造价经测算,文中介绍的方法比规定的钢筋砖过梁的造价要高得多。首先,钢筋用量增加了1倍多。其次,用混凝土替代砂浆,细石混凝土的单方造价也比砂浆单方造价高得多。另外,因板薄,起板、运输、安装时易断裂,会造成较多的破损浪费。 “Building Workers” published the article “Prefabricated Reinforced Concrete Beams Construction” (hereinafter referred to as “pre-text”) in the 3rd issue of 1998. We believe that this method is not desirable and should not be promoted for the following reasons. 1. The waste of materials and the increase of project cost are estimated. The method described in the article is much higher than the cost of the stipulated rebar truss. First of all, the use of reinforcing bars has more than doubled. Second, using concrete instead of mortar, the unilateral cost of fine stone concrete is much higher than that of mortar alone. In addition, due to the thin plate, it is easy to break when it is lifted, transported, and installed, resulting in more damage and waste.
