Manufacturing method of plate rib type prefabricated composite floor slab
The invention discloses a manufacturing method of a plate rib type prefabricated composite floor, which belongs to the field of constructional engineering and comprises the following steps of: 1, placing a prefabricated plate with a key groove on a mold table; 2, side molds are arranged on the side portions of the prefabricated slabs, end molds with gravel grooves are arranged at the ends of the prefabricated slabs, openings of the gravel grooves face upwards, and the gravel grooves are filled with gravel; 3, a truss is arranged in the gravel groove, chord ribs of the truss are anchored into gravel, and bottom ribs protrude out of the upper surface of the prefabricated slab; prestressed reinforcements are arranged in the length direction of the prefabricated slab, and the two ends of the prestressed reinforcements penetrate through the end molds and are fixed through prestressed pedestals; distribution bars are arranged in the width direction of the prefabricated slab; 4, a cast-in-place concrete layer is poured in the area defined by the end formworks and the side formworks; and 5, the side molds and the end molds are dismantled after maintenance, and gravel is cleaned till the truss and the coarse aggregate of the cast-in-place concrete layer are exposed. According to the method, exhaust of the cast-in-place concrete layer is smooth, the shear resistance of the cast-in-place concrete layer is good, the connection performance of the overlapping face is good, and the size precision is high.
本发明公开了一种板肋式预制组合楼板的制作方法，属于建筑工程领域，包括以下步骤：步骤1.将带键槽的预制板放置在模台上；步骤2.在预制板的侧部设置侧模，端部设置带砂砾槽的端模，砂砾槽槽口朝上，砂砾槽内填充砂砾；步骤3.在砂砾槽内布置桁架，桁架的弦筋锚入砂砾内，底筋凸出于预制板的上表面；沿预制板的长度方向布置预应力钢筋，预应力钢筋的两端穿过端模并用预应力台座固定；沿预制板的宽度方向布置分布筋；步骤4.在端模和侧模围合形成的区域内浇筑现浇混凝土层；步骤5.养护后拆除侧模和端模，清理砂砾至露出桁架和现浇混凝土层粗骨料。本发明涉及的方法现浇混凝土层排气顺畅，现浇混凝土层的抗剪性能墙，叠合面的连接性能好，尺寸精度高。
