近期检查了几个在施钢结构项目工地，看到的钢结构安装形式有管桁架、门式钢架、钢框架等，也发现了一些问题。那么钢结构检查与验收环节的注意事项怎样呢？下面济南轻型钢结构厂家为您讲解。

Recently, several domestic and foreign steel construction project sites have been inspected, and the steel structure installation forms seen include pipe truss, portal steel frame, steel frame, etc., and some problems have also been found. What are the precautions for the inspection and acceptance of steel structures? Next, Jinan light steel structure manufacturer will explain to you.

钢结构制作时，应主要关注构件表面的喷砂效果。大部分构件表面的喷砂等级为Sa2.5级，如果达不到这个级别，防锈底漆涂装的附着力就不够，构件到达现场后，尤其是在潮湿、有盐雾的海边地区，将对结构件的防锈带来不利的影响。

During the fabrication of steel structure, the sandblasting effect of the component surface shall be mainly concerned. The sandblasting grade of most component surfaces is Sa2.5. If this grade is not reached, the adhesion of the antirust primer coating will not be enough. After the components arrive at the site, especially in the humid and salt fog coastal areas, it will have a negative impact on the antirust of structural components.

还要关注构件涂装完防锈底漆、中间漆后的效果和涂装范围，涂装完的构件表面应该均匀、无明显皱皮、流坠、针眼、和气泡。

Attention should also be paid to the effect and coating range of the components after the application of anti-rust primer and intermediate paint. The painted component surface should be uniform and free of obvious wrinkles, sags, pinholes and bubbles.

若监理无特殊要求，对摩擦连接的接触面要封牛皮纸，保护摩擦连接面，使其不被油漆污染，若防护不到位，该面有油漆，到达现场后，必须使用电动钢刷进行打磨，不得使用砂轮打磨。

If the supervisor has no special requirements, the contact surface of the friction connection shall be sealed with kraft paper to protect the friction connection surface from paint pollution. If the protection is not in place, the surface has paint. After arriving at the site, it must be polished with electric steel brush instead of grinding wheel.

构件准备出厂之前，应尽量进行钢结构预拼装，尤其是空间管桁架形式，拼装的主要目的是、发现安装问题，同时检验制作的精度和构件焊接所需要预留的焊接间隙的正确性，以及高强螺栓连接的100%通过性。

Before the components are ready to leave the factory, the steel structure shall be pre-assembled as much as possible, especially in the form of space pipe truss. The main purpose of the assembly is to eliminate and find installation problems, and at the same time, the accuracy of the fabrication and the correctness of the welding gap required for the welding of the components, as well as the 100% passability of the high-strength bolt connection.

此外在钢结构涂装过程中，现场项目部要置备湿度计，监测涂装现场的环境湿度。若空气湿度大于85%，则不可进行涂装施工，包括防腐涂装和防火涂装，这点必须引起重视。

In addition, during the coating process of steel structures, the on-site project department shall prepare a hygrometer to monitor the environmental humidity at the coating site. If the air humidity is greater than 85%, the coating can not be carried out, including anti-corrosion coating and fireproof coating, which must be paid attention to.

门型钢架（厂房）安装必须先安装有柱间支撑部位，保证结构形成稳定的空间体系，并不会导致结构变形。不得从任意一头安装，以免出现倒塌。更多相关事项就来我们网站http://www.jnghbxg.com进行咨询吧!

The portal steel frame (plant) must be installed with the support between columns to ensure that the structure forms a stable space system and will not cause permanent deformation of the structure. Do not install from either end to avoid collapse. Come to our website for more relevant matters http://www.jnghbxg.com Consult!
