支撑楼板混凝土的压型钢板称为压型钢板，也称楼承板和钢承压板。下面介绍一下它的特点和注意事项。

The profiled steel plate supporting the floor concrete is called profiled steel plate, also known as floor bearing plate and steel bearing plate. Here are its features and precautions.

楼承板的特征:

Characteristics of floor bearing plate:

1.满足主体钢结构快速施工的要求，在短时间内提供牢固的工作平台，采用多层铺设压型钢板，分层浇筑混凝土板的流水施工。

1. Meet the requirements of rapid construction of the main steel structure, provide a solid working platform in a short time, and adopt the flow construction of laying profiled steel plates in multiple layers and pouring concrete slabs in layers.

2.在使用阶段，采用楼承板作为混凝土楼板的受拉钢筋，也提高了楼板的刚度，节省了钢筋和混凝土的用量。

2. In the use stage, the floor bearing plate is used as the tensile reinforcement of the concrete floor, which also improves the rigidity of the floor and saves the amount of reinforcement and concrete.

3.压型钢板表面的压花可以使楼承板与混凝土产生较大的粘结力，使其形成一个整体，加上加劲肋，使楼承板体系具有较高的承载力。

3. The embossing on the surface of profiled steel plate can make the floor bearing plate and concrete produce a large bonding force, so that it forms a whole. With stiffeners, the floor bearing plate system has a high bearing capacity.

4.在悬臂状态下，楼承板仅用作模板。悬臂的长度可以根据楼承板的截面特性来确定。为了防止悬臂板开裂，应根据结构工程师的设计在支撑处安装负筋。

4. In the cantilever state, the floor bearing plate is only used as a formwork. The length of the cantilever can be determined according to the section characteristics of the floor bearing plate. In order to prevent the cantilever plate from cracking, negative reinforcement should be installed at the support according to the design of the structural engineer.

Precautions for Jinan floor bearing plate:

一般钢结构的柱网间距为5~9.0m×8~15m，次梁间距为3m，而楼承板的下料长度为4.97~8.97m，运输安装困难，特别是从圆弧区域垂直吊装带时，从上到下次梁之间难以穿套，打乱了次梁的正常焊接过程。

The column grid spacing of general steel structure is 5~9.0m × 8~15m, the spacing between secondary beams is 3M, while the blanking length of the floor bearing plate is 4.97~8.97m, which makes it difficult to transport and install. Especially when the belt is vertically hoisted from the arc area, it is difficult to wear a sleeve from top to the next beam, disrupting the normal welding process of the secondary beam.

如果下料长度控制在3~6m，就可以避免垂直运输时次梁无法吊装的问题。起吊时应使用楼承板专用软吊索。每次起吊时，检查软吊索是否撕裂或切割。楼承板探头放在钢梁上时要防止。

If the blanking length is controlled at 3~6m, the problem that the secondary beam cannot be hoisted during vertical transportation can be avoided. Special soft slings for floor bearing plates shall be used for lifting. During each lifting, check whether the soft sling is torn or cut. When the floor bearing plate probe is placed on the steel beam, it should be prevented.

操作人员在铺设材料时应佩戴安全带，并确保在铺设材料时将其固定在周围的安全绳上。焊接熔透点焊用于连接。焊接前应准备好废弧试焊，调整好焊接电流。

Operators shall wear safety belts when laying materials and ensure that they are fixed on the surrounding safety ropes when laying materials. Welding penetration spot welding is used for connection. Before welding, the waste arc test welding shall be prepared and the welding current shall be adjusted.

由于楼承板底部没有水平模板和垂直支撑，浇筑混凝土时布料不能过于集中，要用平板振动器及时分担振动。楼承板的特征和注意事项就是这样了，您可以关注我们网站http://www.jnhxtcg.com了解更多。

Since there is no horizontal formwork and vertical support at the bottom of the floor bearing plate, the distribution of concrete cannot be too concentrated, and the vibration should be shared in time with a flat vibrator. This is the characteristics and precautions of the floor support plate. You can pay attention to our website http://www.jnhxtcg.com Learn more.
