The utility model has the advantages of strong environmental adaptability, fast installation speed, long service life, thermal insulation, etc. It is widely used in road, railway, construction and other field operations of temporary buildings. With the continuous improvement of people's safety awareness, the lightning protection problem of container mobile house in steel structure engineering has become the main concern of customers, so it is necessary to install lightning protection device. So, how to do the lightning protection work of container activity room well? Below with container room small make up to understand together!

怎樣做好防雷工作?

How to do lightning protection work well?

屋防雷，主要包括外部防雷系統(tǒng)、和內(nèi)部防雷系統(tǒng)，金屬屋面防雷屬于外部防雷系統(tǒng)，傳統(tǒng)建筑的防雷模式，是富蘭克林的傳統(tǒng)避雷針、或避雷針結合防雷網(wǎng)絡。

The metal roof lightning protection belongs to the external lightning protection system. The lightning protection mode of traditional buildings is Franklin's traditional lightning rod, or lightning rod combined lightning protection network.

然而，彩鋼屋面板的金屬板相對較薄，因此不可能安裝又高又重的傳統(tǒng)避雷針，因此，在設計金屬屋面建筑時，應根據(jù)防雷設計的五個要素，考慮如何防止屋面雷擊。

However, the metal plate of color steel roof panel is relatively thin, so it is impossible to install high and heavy traditional lightning rod. Therefore, in the design of metal roof building, we should consider how to prevent roof lightning according to the five elements of lightning protection design.

1、建筑物內(nèi)外防雷裝置的接閃器功能

1. Lightning arrester function of lightning protection devices inside and outside buildings

安裝在活動房屋內(nèi)的接閃器，可根據(jù)實際情況采用避雷針、避雷帶或防雷網(wǎng)等接閃器，所選接閃器應具有特定的耐電流和耐壓性、連續(xù)接閃器效果，以及接閃器與建筑物之間的美觀統(tǒng)一性。

The lightning arrester installed in the movable house can use lightning rod, lightning strip or lightning protection net according to the actual situation. The selected lightning arrester should have specific current resistance and voltage resistance, continuous lightning arrester effect, and aesthetic unity between the lightning arrester and the building.

2、下行導線的分流效果

2. Shunting effect of downward conductor

下行導線的厚度和數(shù)量直接影響分流效果，如果有許多引下線，通過每個引下線的雷電電流很小，感應范圍也很小。

The thickness and number of down conductors directly affect the shunt effect. If there are many down conductors, the lightning current passing through each down conductor is very small, and the induction range is also very small.

引下線之間的距離，不應小于規(guī)范中的規(guī)定，當建筑物很高且引下線很長時，應在建筑物中間增加一個均壓環(huán)，以降低引下線的電感壓降。

The distance between down conductors shall not be less than that specified in the specification. When the building is very high and the down conductor is very long, a grading ring shall be added in the middle of the building to reduce the inductive voltage drop of down conductors.

3、活動室內(nèi)各部分電位平衡

3. Potential balance of each part in activity room

為滿足防雷裝置的要求，防雷裝置應與梁、板、柱、基礎可靠焊接、綁扎或搭接，各種金屬設備和金屬管道應同時焊接或夾緊在一起，這使得整個活動房屋成為一個良好的等電位體。

In order to meet the requirements of the lightning protection device, the lightning protection device should be reliably welded, bound or lapped with the beam, plate, column and foundation, and all kinds of metal equipment and metal pipes should be welded or clamped together at the same time, which makes the whole movable house a good equipotential body.
              

4、接地效果

4. Grounding effect

良好的接地效果，是防雷成功的重要保證之一，集裝箱活動房防雷接地設置，應符合設計和規(guī)范要求，接地電阻測試合格。

Good grounding effect is one of the important guarantees for the success of lightning protection. The lightning protection grounding setting of container mobile room should meet the design and specification requirements, and the grounding resistance test should be qualified.

采用獨立接地方式時，鉆深埋接地極(約4~12m)效果為好，深孔接地極可以輕松到達地下水位，降低接地極的用鋼量。

When the independent grounding mode is adopted, the effect of drilling deep buried grounding electrode (about 4 ~ 12m) is better. The deep hole grounding electrode can easily reach the groundwater level and reduce the steel consumption of grounding electrode.

5、有效走線

5. Effective routing

在集裝箱活動房的防雷設計中，務必考慮到防雷系統(tǒng)與這種管道的關聯(lián)，為了確保在防雷設施接閃時這種管道沒受危害，應當將這種電纜線穿于金屬軟管內(nèi)，以保持靠譜的屏蔽掉。

In the lightning protection design of container mobile house, the connection between the lightning protection system and the pipeline must be considered. In order to ensure that the pipeline is not harmed when lightning protection facilities are connected, the cable should be put through the metal hose to keep reliable shielding.

然后把這種路線的主干線，豎直一部分設定在高層住宅房屋建筑的管理中 心位置，且防止挨近作為引退出的柱筋，以盡可能變小被磁感應的范疇。

Then, the vertical part of the main line of this route is set at the management center of high-rise residential buildings, and it is prevented from getting close to the column bar as the exit, so as to reduce the area of magnetic induction as much as possible.
