Method for manufacturing fan reserved hole of roof prefabricated slab
The invention provides a fan reserved hole of a roof prefabricated slab. The fan reserved hole of the roof prefabricated slab comprises a steel frame beam and the roof prefabricated slab. The roof prefabricated slab is of a U-shaped structure. The outer surface of the upper end of the roof prefabricated slab has a length of 200 mm. The height of the roof prefabricated slab is 670mm, and the steelframe beam is arranged at the position, close to one side, of the outer surface of the lower end of the roof prefabricated slab. A method for manufacturing the fan reserved hole of the roof prefabricated slab comprises the following steps that the roof prefabricated slab is poured in the factory; according to the method for manufacturing the fan reserved hole of the roof prefabricated slab, firstthe prefabricated slab is poured in the factory, then a mold is erected at the opening position, steel bars are tied, concrete pouring is carried out to manufacture the fan reserved hole, and then theprefabricated slab and the fan reserved hole are maintained. The on-site installation eliminates the process of manufacturing the hole, and other roof manufacturing methods can be directly carried out, the work efficiency of users is improved, and the use efficiency of roof prefabricated slab is improved.
本发明提供了一种屋面预制板风机预留洞口，包括钢架梁与屋面预制板，所述屋面预制板呈U型结构，所述屋面预制板的上端外表面的长度为200mm，所述屋面预制板的高度为670mm，所述屋面预制板的下端外表面靠近一侧的位置设置有钢架梁，一种屋面预制板风机预留洞口的制作方法，包括如下步骤：在工厂浇筑屋面预制板；这种屋面预制板风机预留洞口的做法是在工厂先浇筑好预制板，然后在洞口位置支模、绑扎钢筋、浇筑混凝土来制作出风机预留洞口，然后对预制板及风机预留洞口进行养护，现场安装省去了制作洞口的工序，可直接进行其他屋面的做法，提高使用者的工作效率，提高屋面预制板的使用效率。
