大家都知道在安裝卷簾門的時(shí)候，經(jīng)常都用到膨脹螺絲，但是要想把膨脹螺絲固定好，卻不是一件簡(jiǎn)單的事情。濟(jì)南富強(qiáng)門業(yè)從事安裝卷簾門的實(shí)踐中，積累了經(jīng)驗(yàn)，在這里和朋友們一塊分享一下。
We all know that the expansion screw is often used when installing the rolling shutter door, but it is not a simple thing to fix the expansion screw well. Jinan Fuqiang door industry engaged in the installation of rolling shutter door practice, accumulated experience, here and friends to share.
普通卷簾門，在門簾包括卷軸包箱和墻面的結(jié)合處用的著膨脹螺絲，固定軌道的時(shí)候也用得著膨脹螺絲，電動(dòng)門在電動(dòng)卷軸兩側(cè)的輪盤上用得著膨脹螺絲，還有包箱的兩側(cè)方盤和電動(dòng)門軌道也用得著膨脹螺絲等等。
For ordinary rolling shutter doors, expansion screws are used at the joint of the curtain, the box and the wall. The expansion screws are also used for fixing the track. The expansion screws are used for the wheel discs on both sides of the electric reel for the electric doors. The expansion screws are also used for the square plates on both sides of the bag box and the electric door track.


在用電錘打膨脹螺絲孔的時(shí)候，因?yàn)閴锩娴臉?gòu)造組成不同，在使用同一號(hào)膨脹螺絲的時(shí)候，把膨脹螺絲螺母擰緊到高限，其膨脹力大小不同，遇到松軟的構(gòu)造成分，膨脹力度會(huì)達(dá)不到要求，遇到這樣的情況，也需要調(diào)整大一些的膨脹螺絲去配備，具體配多大的，要看能不能將螺絲擰緊到高限能否達(dá)到力度要求為標(biāo)準(zhǔn)。
When using an electric hammer to punch the expansion screw hole, because of the different structural composition in the wall, when using the same expansion screw, the expansion screw nut is tightened to the high limit, and the expansion force is different. In case of soft structural components, the expansion strength will not meet the requirements. In such a case, it is also necessary to adjust the larger expansion screw to equip, and how large the expansion screw is, It depends on whether the screw can be tightened to the high limit and whether it can meet the strength requirements.
但是還會(huì)遇到特殊情況，就是用再大的膨脹螺絲也達(dá)不到要求咋辦，我們會(huì)用適當(dāng)?shù)慕饘俾萁z桿將墻穿透，固定面的背面，用合適的金屬桿和穿透墻的金屬桿焊接結(jié)實(shí)，再去固定墻正面的其他構(gòu)件。只有這樣才能保證卷簾門安裝結(jié)實(shí)，堅(jiān)固耐用，叫客戶們用的舒心放心。
But there will be special cases, even if the expansion screw can not meet the requirements. We will use the appropriate metal screw rod to penetrate the wall, fix the back of the fixed surface, weld the appropriate metal rod and the metal rod penetrating the wall firmly, and then fix the other components on the front of the wall. Only in this way can we ensure that the rolling shutter door is installed firmly and durable, so that customers can feel comfortable and at ease.
