空气绝缘桥架热浸镀锌的托盘桥架镀层表面应均匀,无毛刺、过烧、挂灰、伤痕、局部为镀锌等缺陷,不得有影响安装的锌瘤,螺纹的镀层应光滑;螺栓连接件应能拧入。喷涂桥架应平整、光滑、均匀、不起皮、无气泡水泡。
The coating surface of hot-dip galvanized tray tray of air insulated tray shall be uniform, free of defects such as burr, over burning, ash hanging, scar and local galvanization, without zinc tumor affecting installation, and the coating of thread shall be smooth; Bolted connections shall be screwed in. The spraying bridge shall be flat, smooth, uniform, free of peeling and bubbles.
桥架焊缝表面均匀,不得有漏焊、裂纹、夹渣、烧穿、弧坑等缺陷。各类弯通及附件规格,应适合工程布置条件,并与托盘、梯架配套;支吊架规格选择,应按托盘、梯架规格配置,并应满足荷载的要求。根据施工图确定始端到终端位置,沿图纸标定走向,找好水平、垂直、弯通,用粉线袋或画线沿桥架走向在墙壁、顶棚、地面、梁、板、柱等处弹线或画线,并均匀档距画出支、吊、托架位置。
The weld surface of the bridge shall be uniform and free of defects such as missing welding, crack, slag inclusion, burn through and arc pit. The specifications of various bends and accessories shall be suitable for the engineering layout conditions and shall be matched with pallets and ladders; The specifications of supports and hangers shall be configured according to the specifications of trays and ladders, and shall meet the requirements of load. Determine the position from the beginning to the end according to the construction drawing, mark the direction along the drawing, find the horizontal, vertical and curved connection, snap lines or draw lines along the bridge direction on the walls, ceilings, floors, beams, plates, columns, etc., and draw the positions of supports, hoists and brackets with uniform span.
1.空气绝缘桥架支吊架安装支架与吊架所用钢材应平直,无显著扭曲。下料后长短偏差应在3mm范围内,切口处应无卷边、毛刺。
1. The steel used for the installation of supports and hangers of air insulated bridge shall be straight without significant distortion. After blanking, the length deviation shall be within 3mm, and the notch shall be free of curling and burr.
2.空气绝缘桥架钢支架与吊架应焊接牢固,无显著变形,焊接前厚度超过4mm的支架、铁件应打坡口,焊缝均匀平整,焊缝长度应符合要求,不得出现裂纹、咬边、气孔凹陷、漏焊等缺陷。
2. The steel support and hanger of air insulated bridge shall be welded firmly without significant deformation. Before welding, the support and iron parts with a thickness of more than 4mm shall be beveled, the weld shall be uniform and flat, the weld length shall meet the requirements, and there shall be no defects such as crack, undercut, air hole depression and missing welding.
3.空气绝缘桥架根据支架承受的荷重,选择相应的膨胀螺栓及钻头;所选钻头长度应大于膨胀套管的长度,打孔的深度应以将套管全部埋入墙内或顶板内后为标准,表面平齐为宜。应先清除干净打好的孔洞内的碎屑,然后再用木锤将膨胀螺栓敲进洞内,应保证套管与建筑物表面平齐,螺栓端部外露,敲击时不得损伤螺栓的丝扣。埋好螺栓后,用螺母配上相应的垫圈将支架或吊架直接固定在金属膨胀螺栓上。
3. The air insulated bridge shall select the corresponding expansion bolt and drill bit according to the load borne by the support; The length of the selected drill bit shall be greater than the length of the expansion casing. The drilling depth shall be based on the standard after all the casing is embedded in the wall or roof, and the surface shall be flush. The debris in the drilled hole shall be removed first, and then the expansion bolt shall be knocked into the hole with a wooden hammer. It shall be ensured that the casing is flush with the building surface, the bolt end is exposed, and the screw thread of the bolt shall not be damaged during knocking. After embedding the bolts, fix the supports or hangers directly on the metal expansion bolts with nuts and corresponding washers.
