| 通风预埋短管如何制作、安装？ How to make and install the ventilation embedded short pipe? 施工单位应对各种需要预埋、预制的风管应提前加工和制作，防护通风染毒区的风管材料和制作要满足设计要求。如无设计要求，短管厚度应采用大于或等于3mm的钢板焊接，其焊缝应饱满、均匀、严密不漏气。密闭翼环应采用厚度大于3mm的定送水 保定骨伤骨病 铜鼎铜钟 淤泥固化设备 保定舞蹈 化粪池钢模具 保定网站建设钢板制作，钢板应平整，其翼高为30～50mm，密闭翼环与穿墙短管的结合部应双面满焊。密闭翼环应位于墙体厚度的中间，并应与周围墙体结构钢筋焊牢。穿墙密闭短管的轴线应与墙面垂直，管端面平整。密闭短管两端伸出墙面的长度应大于100mm。墙体开洞处钢筋须在洞口两侧增设八字形钢筋加固处理。 The construction unit shall process and fabricate all kinds of air ducts that need to be embedded and prefabricated in advance, and the materials and fabrication of air ducts in the protective ventilation and poisoning area shall meet the design requirements. If there are no design requirements, the thickness of the short pipe shall be welded with a steel plate greater than or equal to 3mm, and the weld shall be full, uniform, tight and free of air leakage. The closed wing ring shall be made of steel plate with a thickness of more than 3mm. The steel plate shall be flat and its wing height shall be 30 ~ 50mm. The joint between the closed wing ring and the short pipe through the wall shall be fully welded on both sides. The closed wing ring shall be located in the middle of the wall thickness and shall be firmly welded with the structural reinforcement of the surrounding wall. The axis of the closed short pipe passing through the wall shall be perpendicular to the wall, and the end face of the pipe shall be flat. The length of both ends of the closed short pipe protruding from the wall shall be greater than 100mm. The reinforcement at the opening of the wall shall be reinforced by adding eight shaped reinforcement on both sides of the openin |
