楼承板，也被称为压型钢板、钢承板、钢楼承板，在多层建筑中扮演着重要的支承角色，负责承担楼层荷载并向立柱等垂直支撑部位传递。以下是楼承板的种类和厚度的详细介绍：

　　Floor support plate, also known as profiled steel plate, steel support plate, steel floor support plate, plays an important supporting role in multi story buildings, responsible for bearing floor loads and transmitting them to vertical support parts such as columns. The following is a detailed introduction to the types and thicknesses of floor slabs:

　　一、楼承板的种类

　　1、 Types of floor slabs

　　砖混板式楼承板：由砖混构件进行组合形成，属于传统的建筑结构类型。

　　Brick concrete slab floor slab: It is a traditional type of building structure formed by combining brick concrete components.

　　钢筋混凝土板式楼承板：由钢筋混凝土构件进行组合形成，具有较好的承载性能和稳定性。

　　Reinforced concrete slab floor slab: composed of reinforced concrete components, it has good load-bearing performance and stability.

　　预制板式楼承板：由预制混凝土构件进行组合形成，具有较强的防火和防水性能。

　　Prefabricated slab floor slab: composed of prefabricated concrete components, it has strong fire and waterproof performance.

　　钢板混凝土楼承板：由钢筋混凝土和钢板组成，具有较高的承载性能和连通性。

　　Steel reinforced concrete floor slab: composed of reinforced concrete and steel plates, it has high bearing capacity and connectivity.

　　钢筋桁架楼承板：主要材料是细石混凝土底模和钢筋桁架，钢筋桁架是经过处理的高强度钢筋，能承受较大的重量。细石混凝土底模一般用425水泥、细沙、细石等构成，具有良好的稳定性和防潮性。

　　Steel bar truss floor slab: The main materials are fine aggregate concrete bottom formwork and steel bar truss. The steel bar truss is processed high-strength steel bars that can withstand large weights. Fine aggregate concrete bottom formwork is generally composed of 425 cement, fine sand, fine aggregate, etc., which has good stability and moisture resistance.

　　压型钢板楼承板：表面有波浪形状，轻便且便宜，但承载力较低。

　　Pressed steel plate floor support plate: The surface has a wavy shape, which is lightweight and inexpensive, but has a lower bearing capacity.

　　全钢楼承板：完全由钢材制成，通常用于结构较轻或对承载力要求不太高的建筑中。

　　Full steel floor slab: made entirely of steel, usually used in buildings with lighter structures or less demanding bearing capacity.

　　此外，楼承板还可根据形状分为开口楼承板、全闭口型楼承板、燕尾式楼承板（也叫缩口型楼承板）等。

　　In addition, floor slabs can be divided into open floor slabs, fully closed floor slabs, and dovetail floor slabs (also known as tapered floor slabs) according to their shape.

　　二、楼承板的厚度

　　2、 Thickness of floor slab

　　楼承板的厚度规格多样，常见的有0.8mm、1.0mm、1.2mm、1.5mm等，也有0.75mm、0.90mm等规格。楼承板的厚度选择主要取决于其跨度、荷载要求以及使用场景。例如：

　　There are various thickness specifications for floor slabs, commonly including 0.8mm, 1.0mm, 1.2mm, 1.5mm, as well as 0.75mm, 0.90mm, and other specifications. The thickness selection of the floor slab mainly depends on its span, load requirements, and usage scenarios. For example:

　　在正常情况下，当钢梁之间的跨度在2米以内时，可选用厚度为0.75至0.8毫米的楼层板。

　　Under normal circumstances, when the span between steel beams is within 2 meters, floor slabs with a thickness of 0.75 to 0.8 millimeters can be selected.

　　跨度在2至2.5米之间时，可选用0.8至1.0毫米厚的楼层板。

　　When the span is between 2 and 2.5 meters, floor slabs with a thickness of 0.8 to 1.0 millimeters can be selected.

　　跨度在三至4米时，需要用厚度为1.5毫米的楼层板。

　　When the span is between three and four meters, a floor slab with a thickness of 1.5 millimeters is required.

　　超过5米的跨度时需要加临时支撑。

　　Temporary support is required when the span exceeds 5 meters.

　　在实际应用中，建议根据具体的设计要求和使用场景选择合适的楼承板厚度，以确保其承载能力和使用寿命。

　　In practical applications, it is recommended to choose the appropriate thickness of the floor slab based on specific design requirements and usage scenarios to ensure its bearing capacity and service life.

　　综上所述，楼承板的种类和厚度多样，选择时需要根据具体的使用场景和设计要求进行综合考虑。

　　In summary, there are various types and thicknesses of floor slabs, and the selection needs to be comprehensively considered based on specific usage scenarios and design requirements.
