There are more and more application scenarios of floor support plate, but there are still many people who don't know the thickness of this floor support plate. Today, let's see how to choose the thickness of the floor bearing plate.
There are more and more application scenarios of floor support plate, but many people still don't know the thickness of this kind of floor support plate. Today, let's take a look at how to select the thickness of the floor bearing plate.
The floor bearing plate is mainly used as the formwork, but there are also closed floor bearing plates as the structural part of the floor. Therefore, different customers will be confused when using it. Mainly reflected in: first, I don't know how to choose the thickness; 2、 Selection of materials. Let's first introduce the characteristics and design requirements of these two kinds of floor bearing plates:
1、 Open floor bearing plate. The bearing plate of this floor slab is mainly used as a formwork. His requirement is not to rust in the construction stage and not to collapse and deform in the construction stage. Generally speaking, our galvanizing quantity is not less than 80g, but due to market competition, the products produced by some steel mills are only 40g, or the design institute does not require galvanizing in architectural design. In this way, the common galvanized coil is widely used in various small buildings. We have also encountered many projects using open floor bearing plates, which have certain requirements for galvanizing: for example, Nanjing Greenland project, yx51-226-678 floor bearing plates need 120g galvanizing.
2、 Closed floor bearing plate. As the bearing part of the floor, the design institute will have material requirements and galvanized content requirements (Q345B material, 275g). But in fact, some of our customers will reduce the material requirements when choosing: for example, the profile steel plate of Shucheng gymnasium adopts Q345B material with thickness of 0.8, and there is no requirement for zinc content. In fact, this is not in line with the design - but this is the reality.
