Consumer friends must pay attention to its specifications and models when purchasing floor bearing plates. If you encounter problems you don't understand, please consult the floor bearing plate manufacturer at any time. If you randomly select the specifications and models of floor bearing plates, it will directly affect the project quality!
First of all, the wave height of the floor support plate shall be selected according to the thickness of the whole floor. Generally speaking, the lower the wave height, the lower the bearing capacity, and then the greater the wave crest distance, the smaller the bearing capacity. According to the requirements of China Steel navel concrete construction standard, the concrete protective layer on the reinforcement shall not be less than 2.5cm, that is, the wave height of the floor support plate itself + the thickness of the steel mesh (generally 2cm) + 2.cm protective layer ≤ floor thickness. Therefore, if the thickness of the whole floor is within 10cm, 7U it is better to choose wave height 40 series, and the thickness of the whole floor is within 10-13cm, Zui is better to choose wave height 50 series, and Zui is better to choose wave height 75 series if it is more than 13cm.
The thickness of the floor support plate is selected. The thickness of the floor support plate mainly depends on the thickness of the floor slab and the distance from the secondary beam of the steel structure. This calculation is very technical! It is calculated based on the section modulus and section moment of inertia of the floor support plate
