预制钢筋混凝土空心板已广泛用在民用建筑的楼板及屋面板中。目前预制多孔板基本上是园孔空心板,也有方孔和椭园孔的。板厚一般为120毫米及180毫米,园孔通常为φ83及φ140。空心楼板在砖墙上搁置长度以10毫米为宜,端头孔一般用预制混凝土块填塞或砂浆红砖堵砌。空心板端头堵孔的作用: 1.防止搁置在烟道孔部份的空心板串烟; 2.用在厨房、卫生间的空心板一旦沿孔漏水,可防止串水;
Prefabricated reinforced concrete hollow slabs have been widely used in the floor slabs and roof slabs of civil buildings. At present, the prefabricated porous plate is basically a hollow hollow plate, and also has a square hole and an elliptical hole. The plate thickness is generally 120 mm and 180 mm, and the holes are usually φ83 and φ140. The length of the hollow floor slab is preferably 10 mm on the brick wall. The end holes are usually plugged with precast concrete blocks or mortar bricks. The role of hollow plate end plugging holes: 1. To prevent the strands of cigarettes stranded in the flue hole part; 2. Used in the kitchen, bathroom hollow plate once the leakage of water along the hole, can prevent string of water;
