资料简介:

将检验项目:
1、熟悉图纸,找出图纸所示的各个避雷接地的接地体的位置,需要焊接的部位等;
2、在土建施工无防水要求的基础或深基础时,根据图纸和设计的要求部位,弹线定位所需要焊接钢筋的位置;
3、根据图纸要求,将底板筋搭接焊好,钢筋的搭接尺寸应不小于直径的6倍。且应双面施焊,焊接牢固,并应清除焊渣。
4、在将主筋与底板筋进行搭接焊,检查不应有漏焊,且主筋的根数不少于2根,并在地面以下焊接接地连接板,并应及时清理焊渣。
5、在回填土完毕后,应测试接地电阻,若不满足,可从接地连接板做人工接地体,达到满足设计要求为止。
6、避雷带施工:避雷卡子的间距应控制在1m,且应生根于女儿墙的圈梁,避雷带的搭接焊,应在镀锌圆钢的6倍以上(即100mm左右),在阴阳角等部位应做成圆弧状,避雷带应与屋顶所有铁质器件可靠连接,保证接地连续性,最后将引下线(不少于2根主筋)分别与避雷带可靠焊接。

The test items:
1, familiar with the drawings, as shown in the drawings to identify the various lightning grounding of grounding position, need to weld the parts, etc.;
2, no water required in the civil construction of deep foundation or basis, in accordance with the requirements of design drawings and parts, playing the line needed to locate the location of welded steel;
3, according to drawings, the bottom bar lap weld, lap steel bar size shall be not less than 6 times the diameter. And facilities should be double-sided welding, welding firm, and should remove welding slag.
4, longitudinal bars and floor in the bar for lap welding, welding inspection should not be tainted, and the root of the number of longitudinal bars of not less than two, and welding in the ground below ground interconnect, and should promptly clean up welding slag.
5, in the backfill has been completed, ground resistance should be tested, if met, can be done manually from the ground interconnect grounding, to meet the design requirement.
6, with construction of lightning: lightning fastener spacing should be controlled at 1m, and should be rooted in the parapet of the ring beam, lightning with the lap welding, galvanized round steel should be more than 6 times (that is 100mm or so), the Yin and Yang angle were to be made arc-shaped, with lightning all the iron roof of the device should be reliable connection, to ensure ground continuity, and finally deflectors (not less than two longitudinal bars) were reliable and lightning with welding.
