開(kāi)口樓承板在施工過(guò)程中是否應(yīng)該留洞，以及留洞大小的影響，了解透徹詳情，對(duì)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(kāi)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(guò)程中，洞口的尺寸大于500mm*500mm時(shí)，這個(gè)時(shí)候，施工人員應(yīng)該先開(kāi)洞，反側(cè)，如果小于這個(gè)尺寸，那就是后開(kāi)洞。其實(shí)，在實(shí)際的工作過(guò)程中，應(yīng)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(shí)很多人都知道，樓承板在鋪設(shè)時(shí)候，是直接在鋼梁上用焊釘穩(wěn)定的，施工人員鋪設(shè)樓承板是想在樓面中間留出一個(gè)口子裝其他東西，這時(shí)候，如果是先開(kāi)洞的話(huà)，樓承板樓面承受的承載能力會(huì)大大收到影響，將有可能影響到施工質(zhì)量。重要的是，先開(kāi)洞的話(huà)，如果是次梁跨度小的話(huà)，影響應(yīng)該不大，萬(wàn)一是跨度超過(guò)了承受范圍，這是一件很危險(xiǎn)的事情，樓承板就相當(dāng)于懸在空中沒(méi)有支撐能力，混凝土如果不夠堅(jiān)固的話(huà)，還有可能發(fā)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.
