The invention discloses a prestressed hollow floor slab and a construction method thereof, and relates to the technical field of prefabricated floor slabs. The prestressed hollow floor slab comprisesa slab body, longitudinal bars and transverse bars are arranged in the slab body, the slab body further comprises transverse bar grooves, the transverse bars penetrate through the transverse bar grooves and match with the transverse bar grooves, slopes are arranged on the two sides of the slab body, and the length of the transverse bars does not exceed the slopes; and the construction method of the prestressed hollow floor slab comprises the following steps that 1, the floor slabs are hoisted; 2, the floor slabs are arranged, and the side faces are spliced; 3, a prefabricated steel bar frame is placed; 4, the transverse bars of the transverse bar grooves are connected with the prefabricated steel bar frame; 5, concrete is poured into a V-shaped groove; and 6, the concrete is solidified andformed. According to the prestressed hollow floor slab and the construction method thereof, the splicing positions of the floor slabs are not prone to cracking, high in the crack resistance, good inthe integrity, are not prone to being damaged or broken at corners, quite convenient in actual production, hoisting and transportation, and the technical problems that the cracking and convenient production and transportation cannot be achieved at the same time in current prefabricated floor slab construction are solved.
本发明公开了一种预应力空心楼板及其施工方法，涉及预制楼板技术领域，包括板体，板体内设有纵筋和横筋，板体还包括横筋凹槽，横筋贯穿横筋凹槽并与横筋凹槽相匹配，板体两侧设有斜面，且横筋长度不超出斜面；一种预应力空心楼板的施工方法，步骤一，吊装楼板；步骤二，将楼板排列，使侧面拼合；步骤三，放置预制钢筋架；步骤四，将横筋凹槽的横筋与预制钢筋架连接；步骤五，将V型槽内浇筑混凝土；步骤六，待混凝土凝固成型；本发明中的一种预应力空心楼板，其楼板拼接处不易开裂、抗裂性强、整体性好，边角处不易破损缺角，实际生产和吊装、运输十分便利，解决了目前预制楼板施工中开裂和便于生产运输不能同时兼有的技术性难题。
