支撐樓板混凝土的壓型鋼板稱為壓型鋼板，也稱樓承板和鋼承壓板。下面介紹一下它的特點和注意事項。

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.

樓承板的特征:

Characteristics of floor bearing plate:

1.滿足主體鋼結(jié)構(gòu)快速施工的要求，在短時間內(nèi)提供牢固的工作平臺，采用多層鋪設(shè)壓型鋼板，分層澆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.在使用階段，采用樓承板作為混凝土樓板的受拉鋼筋，也提高了樓板的剛度，節(jié)省了鋼筋和混凝土的用量。

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.壓型鋼板表面的壓花可以使樓承板與混凝土產(chǎn)生較大的粘結(jié)力，使其形成一個整體，加上加勁肋，使樓承板體系具有較高的承載力。

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.在懸臂狀態(tài)下，樓承板僅用作模板。懸臂的長度可以根據(jù)樓承板的截面特性來確定。為了防止懸臂板開裂，應根據(jù)結(jié)構(gòu)工程師的設(shè)計在支撐處安裝負筋。

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:

一般鋼結(jié)構(gòu)的柱網(wǎng)間距為5~9.0m×8~15m，次梁間距為3m，而樓承板的下料長度為4.97~8.97m，運輸安裝困難，非常是從圓弧區(qū)域垂直吊裝帶時，從上到下次梁之間難以穿套，打亂了次梁的正常焊接過程。

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.

如果下料長度控制在3~6m，就可以避免垂直運輸時次梁無法吊裝的問題。起吊時應使用樓承板專用軟吊索。每次起吊時，檢查軟吊索是否撕裂或切割。樓承板探頭放在鋼梁上時要防止。

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.

操作人員在鋪設(shè)材料時應佩戴安全帶，并確保在鋪設(shè)材料時將其固定在周圍的安全繩上。焊接熔透點焊用于連接。焊接前應準備好廢弧試焊，調(diào)整好焊接電流。

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.

由于樓承板底部沒有水平模板和垂直支撐，澆筑混凝土時布料不能過于集中，要用平板振動器及時分擔振動。樓承板的特征和注意事項就是這樣了，您可以關(guān)注我們網(wǎng)站http://www.xpj55507.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.xpj55507.com Learn more.
