Novel mounting base

The utility model discloses a novel mounting base which comprises a base body, side plates are arranged on the side faces of the base body, a base with the width larger than that of the base body is arranged at the bottom of the base body, at least one side of the base is in gradient connection with the side plates on the side faces of the base body on the same side, and a U-shaped groove is formed in the top of the base body. The prefabricated slab can be lifted through the mounting base, and the situation that the prefabricated slab is soaked in water can be effectively avoided; the area of the base is enlarged, more anti-seepage materials can be contained, the situation of water seepage is more effectively prevented, and corrosion and perforation of the bottom of the prefabricated slab can be effectively prevented; the slope between the base and the side plate can enlarge the included angle in contact with the ground, meets the construction requirements of rooms for purification, and is suitable for being
