国内成熟的比较简单的网架安装工艺有以下几种:The mature and relatively simple grid installation techniques in China are as follows:
1、满堂红脚手架屋面组对工艺:此工艺是从地面搭脚手架一直到屋面下檐,使屋面形成一个大平台,屋面网架就在平台上进行组装。1. Mantanghong scaffolding roof assembly process: This process is to build scaffolding from the ground to the lower eaves of the roof, so that the roof forms a large platform, and the roof grid is assembled on the platform.
此工艺的优点:安全、大型吊装机械使用少、组对速度快、质量有保证。缺点是脚手架搭设工作量大,脚手架用量大,不适合上下交叉施工。The advantages of this process: safety, less use of large hoisting machinery, fast assembly speed, and guaranteed quality. The disadvantage is that the workload of scaffolding is large, and the amount of scaffolding is large, which is not suitable for up and down cross construction.
2、地面分布组对,空中对接工艺:此工艺是在地面将网架组对呈一段一段的网架,由两台抬吊到空中进行分块组对,网架从一头往另一头逐步推进。2. Ground distribution pairing and aerial docking process: This process is to assemble the grids on the ground into a section of grids, and lift them into the air by two sets to carry out block pairing, and the grids are gradually advanced from one end to the other. .
此工艺的有点:节省脚手架的使用,占用馆内施工场地少,无需大吨位起吊设备。能有效解决屋面施工脚手架与地面看台土建施工的矛盾。缺点是:占用两步吊车时间长,高空作业多,空中组对难度大,危险性大。The advantages of this process: save the use of scaffolding, occupy less construction space in the pavilion, and do not need large-tonnage lifting equipment. It can effectively solve the contradiction between roof construction scaffolding and ground stand civil construction. The disadvantages are: it takes a long time to occupy the two-step crane, and there are many high-altitude operations, which makes it difficult and dangerous to assemble in the air.
3、地面小单元组对,空中组对工艺:此方法就是在地面只组对一球三杆,吊到空中进行组装,需要临时支柱配合安装。3. Small unit pairing on the ground, pairing process in the air: This method is to assemble only one ball and three rods on the ground, and then hang them in the air for assembly, which requires temporary pillars to cooperate with the installation.
此工艺优点:速度快,无需大吨位吊车配合,占用场地少,能有效解决屋面作业与看土建同时施工的矛盾。缺点是:高空作业,危险性高。The advantages of this process are: fast speed, no need for large-tonnage cranes, less space occupation, and can effectively solve the contradiction between roofing work and civil engineering construction at the same time. The disadvantage is: high-altitude operation, high risk.
