1.空心方管的用料及质量问题。

1. Material and quality issues of hollow square tubes.

铁艺大门在大陆，现在有一个非常不好的现象，那就是大量的使用空心管材铁料。并不是说不能使用空心管材铁料，而不能使用太薄的方管、圆管。大家看到，由于成本的问题，有的业主、甲方、施工单位、开发商在选购铁艺大门时严重的压价，在招投标过程中，将压的很低，严重者甚会压到低于制作成本，使得有些济南铁艺大门厂家，为了保住成本或者微薄的利润，在材料使用上选用低成本的材料，甚偷工减料，以次充好。有时甲方就公开说明可以使用薄壁的管材。这种情况的出现，都大大减少了铁艺制品的使用寿命。一些铁艺大门大量的使用空心管材铁料，对铁艺大门的系数造成了很大的影响。

The Iron Art Gate is located in mainland China, and now there is a very bad phenomenon, which is the extensive use of hollow pipes and iron materials. This does not mean that hollow pipes and iron materials cannot be used, and too thin square and round pipes cannot be used. As you can see, due to cost issues, some homeowners, party A, construction units, and developers have severely pressed prices when selecting iron art gates. During the bidding process, prices are kept very low, and in severe cases, they may even be lower than the production cost. This has led some Jinan iron art gate factories to choose low-cost materials or even cut corners to replace inferior materials in order to maintain costs or slim profits. Sometimes the first party publicly states that thin-walled pipes can be used. The occurrence of this situation greatly reduces the service life of iron products. Some iron gates heavily use hollow pipes and iron materials, which has a significant impact on the safety factor of iron gates.

2.大型铁艺大门门楼的问题。

2. Safety issues with large iron gate buildings.

由于铁艺大门的门楼高度很高，它的安装和使用的特殊性就显现出来。许多铁艺大门的门楼使用了铸铁花，铸铁花与熟铁的焊接有一定的规范，但因在高空，落差大，在结构设，就要遵守的有关钢结构的设计规范，并针对铸铁花注意一个原则：加强防坠落设计，在结构原理上达到即使铸铁花开焊也不会坠落下来。

Due to the high height of the gate tower of the iron gate, its unique installation and use are evident. Many iron gate gatehouses use cast iron flowers, and there are certain standards for the welding of cast iron flowers and wrought iron. However, due to the high altitude and large drop, when designing the structure, it is necessary to comply with the relevant national design specifications for steel structures, and pay attention to a principle for the cast iron flowers: strengthen anti fall design, and achieve the structural principle that even if the cast iron flowers are welded, they will not fall.

巨型门楼的门柱地脚加强板的设计和处理不用多说，但根部的防水设计不要遗漏，一定要有混凝土式的散水方案，防止根部的雨水侵蚀。为了确保铁艺大门的门楼横跨结构部位在安装时的准确就位，在地面加工过程中要严格控制尺寸公差，在左右两边立柱安装时，严格控制垂直地面，力保吊装时与两面立柱的准确合拢。

It goes without saying much about the design and treatment of the reinforcement plate for the foot of the giant gate tower's door pillar, but the waterproof design at the root should not be overlooked. There must be a concrete style apron plan to prevent rainwater erosion at the root. In order to ensure the accurate positioning of the cross structural parts of the iron gate during installation, dimensional tolerances should be strictly controlled during the ground processing process. When installing the left and right columns, vertical ground should be strictly controlled to ensure accurate closure with the two columns during lifting.

3.铁艺大门工人的人身问题，也是个普遍存在的大问题。

The personal safety issue of iron gate workers is also a common problem.

我们看到，许多铁艺大门作坊的工人，根本无可言，拼命工作，拼命抢工期，血的教训历历在目。出现员工人身事故的主要原因，大多是的意识不足，制度不健全，不重视管理，只图省小钱；在施工之前，没有施工组织设计环节，各种措施和员的配置不到位。

We see that many workers in iron gate workshops have no safety at all, working hard and rushing to work, and the lesson of blood is vividly remembered. The main reasons for employee safety accidents are mostly due to leaders' insufficient safety awareness, inadequate systems, lack of emphasis on management, and a desire to save small amounts of money; Before construction, there was no construction organization design process, and various safety measures and the allocation of safety personnel were not in place.

一要防污染。尤其是在除锈、喷漆作业时，配备防护面具，防止有毒的粉尘、气体、液体侵入体内。

One must prevent pollution. Especially during rust removal and painting operations, protective masks should be equipped to prevent toxic dust, gases, and liquids from entering the body.

二是防触电。电动工具的绝缘和检查，绝缘手套、绝缘鞋的配备，雨天雾天等湿度大的天气时的施工，都要严格遵守操作规程。作业周边环境的电力设施的考察和提防，都要心中有数。

The second is to prevent electric shock. The insulation and inspection of electric tools, the provision of insulated gloves and shoes, and the construction in rainy and foggy weather with high humidity must strictly follow the operating procedures. Be aware of the inspection and precautions for the power facilities in the surrounding environment of the job.

三是防高空坠落。

The third is to prevent high-altitude falls.
