閉口樓承板在施工過程中確實需要澆筑混凝土。以下是閉口樓承板施工的相關要點：

　　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:

　　鋼筋敷設 ：在樓承板上敷設鋼筋，以增強其承載能力和穩定性。

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

　　澆筑混凝土 ：在樓承板上均勻澆筑混凝土，確保其達到設計強度。

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

　　表面處理 ：澆筑完成后，對樓承板表面進行清洗和處理，以提高其美觀性和耐久性。

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

　　排板與連接 ：閉口型組合樓承板排板時，按跨距順排，與鋼梁順接，板底平整，有足夠與鋼梁實接面積，因此不需要額外處理。

　　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 ：由于閉口型組合樓承板與鋼梁的結合方式，鋼梁上翼板頂面無需噴防火涂料。

　　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、鋼筋的選型以及搭接長度等都需要根據具體的設計要求和施工規范來確定。

　　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.
