平卧式预制四角空心方块,块体的脱膜起吊以往采用千斤顶将块体顶活,然后穿纲丝绳兜脚或用钢钩钩底的起吊方法。此方法施工麻烦,速度慢,而且容易损坏块体的棱角。如果采用四脚空心方块专用吊夹,则施工方便,速度快,不易损坏块体的棱角。2~t四角空心方块吊夹整体结构如图1所示。下面简述其设计及应用情况。 Horizontal horizontal prefabricated square hollow block, the lifting of the block lifting the past using the jack to the top of the block live, and then wear a wire rope foot or steel hook hook at the end of the lifting method. This method of construction trouble, slow, and easy to damage the corners of the block. If the use of four-legged Hollow box hanging clamp, the construction is convenient, fast, easy to damage the edges and corners of the block. 2 ~ t four square hollow box hanging clip overall structure shown in Figure 1. The following brief description of its design and application.
