結構建筑體系具有穩定的基礎和堅固的骨架，它逐漸影響著各行業的發展現狀和未來前景。下面我們一起來了解一下鋼結構工程施工的注意事項。

Structural building system has stable foundation and solid skeleton, which gradually affects the development status and future prospects of various industries. Let's take a look at the precautions for steel structure construction.

鋼結構工程施工前要組織監理人員、施工單位技術人員對設計圖紙及相關技術標準進行會審，做好技術交底。

Before the construction of steel structure works, the supervisor and the technical personnel of the construction unit shall be organized to jointly review the design drawings and relevant technical standards, and make technical disclosure.

濟南輕型鋼結構構件入場驗收，確保質量滿足設計要求，內容包括鋼結構規格型號無誤、除銹防銹、焊接質量等。

Jinan light steel structure members were accepted on site to ensure that the quality meets the design requirements, including the correctness of steel structure specifications and models, rust removal and rust prevention, welding quality, etc.

根據設計要求進行基礎預埋地腳螺栓，并進行混凝土澆筑。

According to the design requirements, the foundation shall be embedded with anchor bolts and the concrete shall be poured.

現場吊裝，遵循“先柱后梁、先下后上、從中間往兩邊”的吊裝原則，先進行鋼柱吊裝，吊起柱腳與地腳螺栓相距30厘米左右時人工扶正后擰緊螺栓，完成鋼柱安裝;然后進行鋼梁吊裝，吊裝椽條。

On site hoisting shall follow the hoisting principle of "column before beam, down before up, and from the middle to both sides". The steel column shall be hoisted first. When the distance between the column foot and the anchor bolt is about 30cm, the bolts shall be tightened after manual righting to complete the installation of the steel column; Then the steel beam shall be hoisted, and finally the rafters shall be hoisted.

對吊裝結構進行校正，鋼柱的校正用吊線錘檢測，對出現歪斜的鋼柱用墊板校正;鋼梁的校正用水平儀檢測后用千斤頂和倒鏈進行校正。

The hoisting structure shall be calibrated, the steel column shall be calibrated with a plumb bob, and the steel column with deflection shall be calibrated with a base plate; The steel beam shall be calibrated with a jack and chain block after being tested with a level gauge.

施工安全，因為鋼結構工程的吊裝涉及高處作業和人機協作，操作人員要佩戴安全帽，系掛安全繩，同時需要安全指揮員指揮吊裝。

Construction safety, because the hoisting of steel structure works involves high-altitude operation and man-machine cooperation, the operators shall wear safety helmets and hang safety ropes, and the safety commander is required to command the hoisting.

建筑材料加工制造工藝準備：

Preparation for processing and manufacturing process of building materials:

材料需要有材質證明。

Materials shall have material certificates.

根據設計計算出的每根桿件下料長度和桿件規格，分類堆放，便于下一步施工。

According to the blanking length and specification of each member calculated in the design, it shall be stacked by category for the convenience of the next construction.

根據鋼管的相貫尺寸，考慮壁厚和坡口的影響，采用自動切割機自動切割相貫線。

According to the intersecting size of the steel pipe and considering the influence of the wall thickness and groove, the automatic cutting machine is used to cut the intersecting line automatically.

濟南輕型鋼結構在焊接過程中，為了盡量減少節點處應力集中的不利影響，支管與主管之間的連接焊縫應在一周內連續順利地進行焊接。如果主管有對接焊縫，營口應規劃一個坡口，以確保焊縫熔透。

During the welding process of Jinan light steel structure, in order to minimize the adverse effect of stress concentration at the joint, the connecting weld between the branch pipe and the main pipe should be welded continuously and smoothly within one week. If the main pipe has butt weld, Yingkou shall plan a groove to ensure weld penetration.

質檢人員對焊縫進行超聲波探傷。如果發現不合格焊縫，應進行標記，并及時通知焊工返工。

Quality inspection professionals conduct ultrasonic flaw detection for welds. If unqualified welds are found, they shall be marked and the welder shall be informed to rework in time.

主桁架和次桁架應預組裝成一個單元組并編號。

The main truss and secondary truss shall be pre assembled into a unit group and numbered.

濟南輕型鋼結構構件表面進行干噴砂除銹處理，等級為，刷兩道油性防銹底漆，然后刷表面面漆。

The surface of Jinan light steel structure members shall be subject to dry sand blasting and derusting treatment. The grade is, and two coats of oil-based antirust primer shall be applied, and then the surface finish paint shall be applied.
