How much is the thickness of the floor usually chosen? General floor manufacturers are not standard. In fact, the thickness of the multi thick base plate is mainly determined by the thickness of the floor and the spacing between the secondary beams. This calculation has technical content. It is based on the section modulus of the floor plate, the calculation of the section moment of inertia and other relevant information, and then the judgment basis of the general situation as follows:

　　介绍这两种楼板的特点和设计要求:

　　Firstly, the characteristics and design requirements of these two kinds of floor are introduced

　　，打开地板。此楼板主要用作模板，他的要求是在施工阶段不要生锈，在施工阶段不能出现塌陷变形。一般来说，我们的镀锌量不低于80克，但是由于市场竞争，钢厂生产的产品，有的只有40克，或者设计院在建筑设计中不需要锌的含量。这进一步提高了常见的镀锌线圈用于各种各样的小建筑。

　　First, turn on the floor. This floor slab is mainly used as formwork, and its requirement is not to rust in the construction stage and collapse deformation is not allowed in the construction stage. Generally speaking, our zinc content is no less than 80g, but due to market competition, some products produced by steel mills are only 40g, or the design institute does not need zinc content in architectural design. This further enhances the most common galvanized coil used in a wide variety of small buildings.

　　二、无声地板。作为楼面承载力的一部分，设计院将有材料要求和镀锌量要求(Q345B材料，275克)。然而，事实上，我们的一些客户会降低材料的使用要求。

　　2、 Silent floor. As part of the floor bearing capacity, the design institute will have material requirements and galvanizing requirements (Q345B material, 275g). However, in fact, some of our customers will reduce the use requirements of materials.

　　,本文为您提供了摘要,底板的厚度主要看地板的厚度和间距的次梁,这种计算技术内容,它是基于地板板截面模量,计算截面惯性矩和其他有关资料,小编只是说的一般情况的判断依据:

　　Finally, this paper provides you with a summary. The thickness of the bottom plate mainly depends on the thickness of the floor and the secondary beam of the spacing. This calculation technology is based on the section modulus of the floor plate, the calculation of the section moment of inertia and other relevant information. It is just the judgment basis for the general situation

　　一、正常情况下，钢梁间距在2m以内，底板承重板厚度0.75-0.8mm。

　　1、 Under normal conditions, the spacing between steel beams is within 2m, and the thickness of bearing plate of bottom plate is 0.75-0.8mm.

　　2. 2-2.5m楼板厚度0.8-1.0。

　　2. 2-2.5m floor thickness 0.8-1.0.

　　三、跨度在3-4米的楼板厚度用1.5mm，超过5米的跨度终采用临时支撑。

　　3、 The thickness of the slab with a span of 3-4m is 1.5mm, and the span with a span of more than 5m is finally supported temporarily.

　　以上仅从板厚角度考虑，没有充分考虑板形、强度等因素。还有一个我们往往忽略的因素是，螺杆的好坏也决定了楼板的厚度，螺杆越好，楼板的承载能力就越强。

　　The above is only considered from the perspective of plate thickness, without fully considering the shape, strength and other factors. Another factor that we often ignore is that the quality of the screw also determines the thickness of the floor. The better the screw, the stronger the bearing capacity of the floor.

　　以上是楼板厚度的判断依据，希望对你有所帮助。

　　The above is the judgment basis of floor thickness, hope to help you.
