　　风管安装的质量检验

Quality inspection of air duct installation

　　一、风管安装时应注意的问题

1、 Safety issues to pay attention to during the installation of air ducts

　　1 起吊时，严禁人员在被吊风管下方，风管上严禁站人。

When lifting, it is strictly prohibited for personnel to be under the suspended air duct, and standing on the air duct is strictly prohibited.

　　2 应检查风管内、上表面有无重物，以防起吊时，坠物伤人。

2. Check for heavy objects inside and on the surface of the air duct to prevent injury from falling objects during lifting.

　　3 对于较长风管，起吊速度应同步进行，首尾呼应，防止由于一头过高，中段风管法兰受力大而造成风管变形。

For longer air ducts, the lifting speed should be synchronized and coordinated from head to tail to prevent deformation of the duct due to excessive force on the flange of the middle section due to one end being too high.

　　4 抬到支架上的风管应及时安装，不能放置太久。

The air duct lifted onto the bracket should be installed in a timely manner and should not be left for too long.

　　5 对于暂时不安装的孔洞不要提前打开；暂停施工时，应加盖板，以防坠人坠物事故发生。

Do not open holes that are not temporarily installed in advance; When suspending construction, cover plates should be added to prevent accidents caused by falling people or objects.

　　使用梯子不得缺挡，不得垫高使用。

When using a ladder, do not miss the gear or elevate it.

　　使用梯子的上端要扎牢，下端采取防滑措施。

The upper end of the ladder should be securely fastened and anti slip measures should be taken at the lower end.

　　送风支管与总管采用直管形式连接时，

When the air supply branch pipe is connected to the main pipe in a straight pipe form,

　　插管接口处应设导流装置。

A guiding device should be installed at the insertion interface.

　　二、风管安装质量检验

2、 Quality inspection of air duct installation

　　风管安装后，可用拉线或吊线的方法进行检查。一般只要支吊架安装得正确，风管接得平直，风管应能保持横平竖直。风管安装的允许偏差为水平度不大于3mm/m，总偏差不大于20mm。

After the installation of the air duct, it can be checked by pulling or hanging wires. Generally, as long as the supports and hangers are installed correctly and the air ducts are connected straight, the air ducts should be able to maintain horizontal and vertical straightness. The allowable deviation for the installation of air ducts is that the levelness shall not exceed 3mm/m, and the total deviation shall not exceed 20mm.

　　GB50243-2016《通风与空调工程施工质量验收规范》要求：

GB50243-2016 "Code for Acceptance of Construction Quality of Ventilation and Air Conditioning Engineering" requires:

　　6.2.9 风管系统安装完毕后，应按系统类别要求进行施工质量外观检验。合格后，应进行风管系统的严密性检验，漏风量除应符合设计要求和本规范第4.2.1条的规定外，尚应符合下列规定：

After the installation of the air duct system, the construction quality and appearance inspection should be carried out according to the requirements of the system category. After passing the inspection, the tightness of the air duct system should be inspected. In addition to meeting the design requirements and the provisions of Article 4.2.1 of this specification, the air leakage should also comply with the following regulations:

　　1 当风管系统严密性检验出现不合格时，除应修复不合格的系统外，受检方应申请复验或复检。

When the tightness inspection of the air duct system fails, in addition to repairing the unqualified system, the inspected party should apply for re inspection or re inspection.

　　2 净化空调系统进行风管严密性检验时，N1级～N5级的系统按高压系统风管的规定执行；N6级～N9级，且工作压力小于等于1500Pa的，均按中压系统风管的规定执行。

When conducting air duct tightness inspection on the 2 purification air conditioning system, N1 to N5 level systems shall comply with the regulations for high-pressure system air ducts; For grades N6 to N9, and with a working pressure of less than or equal to 1500Pa, the regulations for medium pressure system air ducts shall be followed.

　　检查数量：微压系统，按工艺质量要求实行全数观察检验；低压系统，按Ⅱ方案实行抽样检验；中压系统，按Ⅰ方案实行抽样检验；高压系统，全数检验。

Inspection quantity: Micro pressure system, implement full observation inspection according to process quality requirements; Low voltage system, implement sampling inspection according to scheme II; Medium voltage system, implement sampling inspection according to Plan I; High voltage system, complete inspection.

　　检查方法：除微压系统外，严密性测试按本规范附录C的规定执行。

Inspection method: Except for the micro pressure system, the tightness test shall be carried out in accordance with the provisions of Appendix C of this specification.
