厨房油烟净化器选择时要注意什么？
翻板车库门的门板顶在墙上无法正常翻转，如果是在安装过程中，一个原因可能是弯轨幅度太小，导致门板顶在天花板上，二是墙壁上有障碍物阻挡活动门板运行；三是双轨的小弯安装不对，检验双轨的安装是否正确，可以看小弯压在大弯上面是否刚好和门板一样高。如果是已经使用了一段时间的车库门出现门板卡主的现象，可以检查一下导轨内部是否有异物卡住，或者是轨道里面的螺丝是否松动，还可以检查一下轮子是否脱轨，如果门板被卡主，建议暂停使用遥控电动开门，以免电机受损。
The top of the door panel of the flap garage door cannot flip normally on the wall. If it is in the installation process, one reason may be that the bending rail amplitude is too small, causing the door panel to top on the ceiling, and the other is that there are obstacles on the wall to block the movement of the movable door panel; Third, the small bend of the double track is not installed correctly. Check whether the installation of the double track is correct. You can see whether the small bend is just as high as the door plate on the big bend. If the garage door that has been used for a period of time is jammed, you can check whether there is foreign matter stuck inside the guide rail, or whether the screws inside the rail are loose, and check whether the wheel is derailed. If the door panel is jammed, it is recommended to suspend the use of remote electric door opening to avoid damage to the motor.
翻板车库门开启以后，钢丝绳是否还在受力的问题。翻板门开启后，活动门板悬挂在天花板下方的轨道上，此时门体的重量由轨道承担，所以这时候钢丝绳是基本不受力的，但是有预紧力在拉着。翻板门开启以后，因为活动门板的重量基本都在轨道上，所以轨道的安装需要进行加固。特别是弯直轨经过的地方有落水管和其他障碍物遮挡，或者直接是悬空的，都可以用三角钢打吊轨进行固定。
Whether the steel wire rope is still under stress after the flap garage door is opened. After the flap door is opened, the movable door panel is suspended on the track under the ceiling. At this time, the weight of the door body is borne by the track, so at this time, the steel wire rope is basically unstressed, but there is a preload pulling. After the flap door is opened, because the weight of the movable door panel is basically on the track, the installation of the track needs to be strengthened. In particular, the place where the curved straight rail passes through is covered by downpipes and other obstacles, or directly suspended, can be fixed by using triangular steel to hit the lifting rail.
这也是为什么我们之前总在讲车库内部障碍物的原因。安装车库门，前提条件就是要求门洞两侧和顶部都得有承重的受力点，这样才能承担得起车库门开启以后的重量。如果是自建房，车库门顶部用的彩钢瓦，彩钢瓦不具备承重功能，屋顶下面又没有承重的横梁，这样的车库就没办法安装翻板车库门，这种情况下可以选择在门口安装卷帘门。
This is why we always talk about obstacles in the garage before. The precondition for installing the garage door is that there must be load-bearing points on both sides and top of the door opening, so that the weight after the garage door is opened can be borne. If it is a self-built house, the color steel tile used on the top of the garage door does not have the load-bearing function, and there is no load-bearing beam under the roof, so the garage cannot install the flap garage door. In this case, you can choose to install the rolling shutter door at the door.
