開口樓承板在施工過程中是否應該留洞，以及留洞大小的影響，了解透徹詳情，對我們的施工以及后期維修都是很有必要的，在此為大家介紹一下開口樓承板施工怎么留洞呢？

Should holes be left in the construction process of open floor support plates, and the impact of hole size? It is necessary to have a thorough understanding of the details for our construction and later maintenance. We would like to introduce how to leave holes in the construction of open floor support plates?

如果留洞的過程中，洞口的尺寸大于500mm*500mm時，這個時候，施工人員應該先開洞，反側，如果小于這個尺寸，那就是后開洞。其實，在實際的工作過程中，應該是先留洞為好。

If the size of the opening is greater than 500mm * 500mm during the process of leaving a hole, the construction personnel should first open the hole on the opposite side. If it is smaller than this size, it is called a later opening. In fact, in the actual work process, it is better to leave a hole first.

什么是先留洞好呢？其實很多人都知道，樓承板在鋪設時候，是直接在鋼梁上用焊釘穩定的，施工人員鋪設樓承板是想在樓面中間留出一個口子裝其他東西，這時候，如果是先開洞的話，樓承板樓面承受的承載能力會大大收到影響，將有可能影響到施工質量。重要的是，先開洞的話，如果是次梁跨度小的話，影響應該不大，萬一是跨度超過了承受范圍，這是一件很危險的事情，樓承板就相當于懸在空中沒有支撐能力，混凝土如果不夠堅固的話，還有可能發生坍塌事件。

What is better to leave a hole first? In fact, many people know that when laying the floor support plate, it is directly stabilized on the steel beam with welding nails. The construction personnel lay the floor support plate to leave a hole in the middle of the floor to install other things. At this time, if the hole is opened first, the bearing capacity of the floor support plate will be greatly affected, which may affect the construction quality. It is important to first open a hole. If the span of the secondary beam is small, the impact should not be significant. If the span exceeds the bearing range, it is a very dangerous thing. The floor support plate is like hanging in the air without support capacity. If the concrete is not strong enough, there is still a possibility of collapse.
