設計要點

Design points

要根據某一系統的某一樓層管道圖紙，并標明接口位置。

According to the pipeline drawing of a certain floor of a system, and indicate the interface location.

管道的設計應從起點開始編號，起點一般為接口位置，相同截面規格相同長度的節點應為相同編號，應按順序編號。為了便于有組織的施工。

The design of pipelines should be numbered from the starting point, which is generally the interface position. Nodes with the same cross-sectional specifications and length should be numbered in the same order. For the convenience of organized construction.

管道的設計應當顯示分支吊架的位置，分支吊架的位置間隔和所有材料的規格需要符合后述規格要求和技術規定。

The design of pipelines should display the position of branch hangers, and the spacing of branch hangers and the specifications of all materials should comply with the following specifications and technical regulations.

山東通風管道的設計應優先考慮彎頭和內徑滿足內外同心彎頭要求內徑長度要求。

The design of ventilation ducts in Shandong should prioritize considering elbows and inner diameters that meet the inner diameter length requirements of concentric elbows.

管道設計應標出彎頭位置變徑位置管道軸線位置管道底部標高。

The pipeline design should indicate the position of the bend, the position of the pipeline axis, and the elevation of the pipeline bottom.

加工需要注意的問題

Issues to be noted in processing

通風管道加工不能在其內部設置鋼筋骨架或鋼筋，如果添加會影響管道的質量。

The processing of ventilation ducts cannot have steel reinforcement skeletons or steel bars installed inside, as adding them will affect the quality of the ducts.

加工不能使用c型直角插入和s型插入的連接方式。 對于特殊管道，不能采用卡扣式咬合口。通風管制作完成后，需要用清洗液清洗，達到標準后才能進行密封。

The connection method of C-shaped right angle insertion and S-shaped insertion cannot be used for processing. For special pipelines, snap on bite openings cannot be used. After the production of the ventilation pipe is completed, it needs to be cleaned with cleaning solution to meet the standards before sealing can be carried out.

減少管道加工過程中出現縱向接縫，不能橫向接縫，并且管道間隙應按照設計的清潔水平要求用密封劑堵塞，管道板材接縫的密封面應位于通風管道壁的正壓側。山東通風管道加工過程中應采取防腐措施。管道零件需要鍍鋅。

Reduce the occurrence of longitudinal joints during pipeline processing, instead of transverse joints, and the pipeline gap should be blocked with sealant according to the design cleanliness level requirements. The sealing surface of the pipeline plate joint should be located on the positive pressure side of the ventilation pipeline wall. Anti corrosion measures should be taken during the processing of ventilation pipes in Shandong. Pipeline parts need to be galvanized.
