闭口楼承板在施工过程中确实需要浇筑混凝土。以下是闭口楼承板施工的相关要点：

　　The closed-end floor slab does indeed require pouring concrete during the construction process. The following are the key points related to the construction of closed-end floor slabs:

　　钢筋敷设 ：在楼承板上敷设钢筋，以增强其承载能力和稳定性。

　　Reinforcement laying: Lay reinforcement on the floor slab to enhance its load-bearing capacity and stability.

　　浇筑混凝土 ：在楼承板上均匀浇筑混凝土，确保其达到设计强度。

　　Pouring concrete: evenly pour concrete on the floor slab to ensure it reaches the design strength.

　　表面处理 ：浇筑完成后，对楼承板表面进行清洗和处理，以提高其美观性和耐久性。

　　Surface treatment: After pouring, clean and treat the surface of the floor slab to improve its aesthetics and durability.

　　排板与连接 ：闭口型组合楼承板排板时，按跨距顺排，与钢梁顺接，板底平整，有足够与钢梁实接面积，因此不需要额外处理。

　　Plate arrangement and connection: When arranging the closed-end composite floor support plates, they should be arranged in sequence according to the span and connected to the steel beams. The bottom of the plate should be flat and have sufficient solid connection area with the steel beams, so no additional treatment is required.

　　防火涂料 ：由于闭口型组合楼承板与钢梁的结合方式，钢梁上翼板顶面无需喷防火涂料。

　　Fireproof coating: Due to the combination of the closed-end composite floor slab and the steel beam, the top surface of the upper wing plate of the steel beam does not need to be sprayed with fireproof coating.

　　需要注意的是，混凝土的厚度、钢筋的选型以及搭接长度等都需要根据具体的设计要求和施工规范来确定。

　　It should be noted that the thickness of concrete, selection of steel bars, and overlap length all need to be determined according to specific design requirements and construction specifications.
