开口楼承板在施工过程中是否应该留洞，以及留洞大小的影响，了解透彻详情，对我们的施工以及后期维修都是很有必要的，在此为大家介绍一下开口楼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?

如果留洞的过程中，洞口的尺寸大于500mm*500mm时，这个时候，施工人员应该先开洞，反侧，如果小于这个尺寸，那就是后开洞。其实，在实际的工作过程中，应该是先留洞为好。

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？其实很多人都知道，楼承板在铺设时候，是直接在钢梁上用焊钉稳定的，施工人员铺设楼承板是想在楼面中间留出一个口子装其他东西，这时候，如果是先开洞的话，楼承板楼面承受的承载能力会大大收到影响，将有可能影响到施工质量。重要的是，先开洞的话，如果是次梁跨度小的话，影响应该不大，万一是跨度超过了承受范围，这是一件很危险的事情，楼承板就相当于悬在空中没有支撑能力，混凝土如果不够坚固的话，还有可能发生坍塌事件。

55世纪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.
