Recently, I came across a post online where someone was asking about how the model of a pressed steel plate is expressed. Before diving into this question, we need to clarify what exactly a "building board" is.
In mainland specifications, when pressed steel plates are used to support floor concrete, they are referred to as "pressed steel plates." Essentially, the term starts with "YX," which stands for "pressure type," followed by the wave height, wave distance, and effective width. Occasionally, it might also be represented using the initials "YXB," standing for "pressed plate."
Now, if you're still a bit confused, let me break it down further with an example. Take the YXB66-240-720 board type as an illustration. This specific type of pressed steel plate was used in the 2018 Youth Construction Group Yantai Port project, supplied by our company in Shandong Shengbo.
Here's what the numbers mean: YXB66-240-720 refers to a pressed steel plate with a wave height of 66mm, a wave distance of 240mm, and an effective width of 720mm. Sometimes, the wave distance is omitted, leaving us with YXB66-720. Alternatively, it could be written as YX66-240-720(B), indicating that it's a closed-end steel plate.
The above explanation provides a very formal way of expressing these models. However, in practice, people in the industry often use shorthand for common types of pressed steel plates. For instance, the "555-type pressed steel plate" corresponds to YXB65-185-555, while "2W" refers to YXB51-305-915, and "3W" to YXB76-305-915.
This shorthand makes communication easier among professionals but can be confusing for those unfamiliar with the terminology. Understanding these details is crucial for anyone involved in construction or related fields, especially when specifying materials for projects.
The lifting ring nut refers to the part that the nut and the bolt or the screw are screwed together for fastening, and it is an original part that all production machinery must use. The lifting ring nut is a commonly used fixing pendant in engineering. There is a thread under the nut, which can be drilled according to its different specifications and fixed by the screw.
