一、概述1.大型预制构件简介大型预制构件指的是构成3个112m 跨的预应力钢筋混凝土构件,不包括挂箱和其他工字梁。计有墩间横梁、塔间横梁、跨中横梁、卡丝梁、短纵梁和工字梁(V_3、V_4)共128件,混凝土体积为4920m~3,总重12300t。构件长短、轻重不一,长5.1m 至63.64m,重37t 至460t。由于预制构件的外形尺寸偏大(偏差为正号),按起重船计算机显示的构
I. Overview 1. Introduction of Large Prefabricated Components Large prefabricated components refer to the three prestressed reinforced concrete components constituting 112m span, excluding hanging boxes and other I-beams. There are 128 pier girders, tower girders, mid-span girders, girder girders, short girders and I-beams (V_3, V_4), with a concrete volume of 4920m 3 and a total weight of 12300t. Length of the components, varying in severity, length 5.1m to 63.64m, weight 37t to 460t. As the prefabricated parts of the larger size (deviation is a positive sign), according to crane ship computer display structure
