近期檢查了幾個(gè)在施鋼結(jié)構(gòu)項(xiàng)目工地，看到的鋼結(jié)構(gòu)安裝形式有管桁架、門式鋼架、鋼框架等，也發(fā)現(xiàn)了一些問題。那么鋼結(jié)構(gòu)檢查與驗(yàn)收環(huán)節(jié)的注意事項(xiàng)怎樣呢？下面濟(jì)南輕型鋼結(jié)構(gòu)廠家為您講解。

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.

鋼結(jié)構(gòu)制作時(shí)，應(yīng)主要關(guān)注構(gòu)件表面的噴砂效果。大部分構(gòu)件表面的噴砂等級為Sa2.5級，如果達(dá)不到這個(gè)級別，防銹底漆涂裝的附著力就不夠，構(gòu)件到達(dá)現(xiàn)場后，尤其是在潮濕、有鹽霧的海邊地區(qū)，將對結(jié)構(gòu)件的防銹帶來不利的影響。

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.

還要關(guān)注構(gòu)件涂裝完防銹底漆、中間漆后的效果和涂裝范圍，涂裝完的構(gòu)件表面應(yīng)該均勻、無明顯皺皮、流墜、針眼、和氣泡。

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.

若監(jiān)理無特殊要求，對摩擦連接的接觸面要封牛皮紙，保護(hù)摩擦連接面，使其不被油漆污染，若防護(hù)不到位，該面有油漆，到達(dá)現(xiàn)場后，必須使用電動(dòng)鋼刷進(jìn)行打磨，不得使用砂輪打磨。

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.

構(gòu)件準(zhǔn)備出廠之前，應(yīng)盡量進(jìn)行鋼結(jié)構(gòu)預(yù)拼裝，尤其是空間管桁架形式，拼裝的主要目的是消除、發(fā)現(xiàn)安裝問題，同時(shí)檢驗(yàn)制作的精度和構(gòu)件焊接所需要預(yù)留的焊接間隙的正確性，以及高強(qiáng)螺栓連接的100%通過性。

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.

此外在鋼結(jié)構(gòu)涂裝過程中，現(xiàn)場項(xiàng)目部要置備濕度計(jì)，監(jiān)測涂裝現(xiàn)場的環(huán)境濕度。若空氣濕度大于85%，則不可進(jìn)行涂裝施工，包括防腐涂裝和防火涂裝，這點(diǎn)必須引起重視。

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.

門型鋼架（廠房）安裝必須先安裝有柱間支撐部位，保證結(jié)構(gòu)形成穩(wěn)定的空間體系，并不會(huì)導(dǎo)致結(jié)構(gòu)變形。不得從任意一頭安裝，以免出現(xiàn)倒塌。更多相關(guān)事項(xiàng)就來我們網(wǎng)站http://1myl.com進(jìn)行咨詢吧!

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://1myl.com Consult!
