As shown in FIGS. 1 to 4 , the anti-dropping device 100 for a clean room waffle bucket includes: a waffle bucket 1 , which is set at a predetermined position when constructing a clean room waffle floor 101 , and then engages with the clean room waffle. In the floor 101, a waffle hole 102 is formed through the clean room waffle floor 101. The inner side of the top of the waffle bucket 1 has a step 11; and a round cover plate 2 is arranged on the top of the waffle bucket 1; The outer edge of the cover plate 2 is provided with a lower flange 3; the bottom of the lower flange 3 has at least a gap 31 and the lower flange is placed on the step 11 of the waffle bucket 1; and at least one fixed elastic piece 4, There is a fixing part 41 and an elastic deformation part 42 arranged on the outer side of the fixing part and extending upward and outward for a predetermined length; the fixing part 41 is fixed in the notch 31 of the lower flange 3, so that the elastic deformation part 42 is set in the Between the lower flange 3 and the inner side surface of the waffle bucket 1; with this structure, it is convenient to use the elastic deformation part when the waffle bucket 1 is deformed The elasticity of 42 fixes the round cover plate 2 on the top of the waffle bucket 1, thereby preventing items such as on-site construction personnel and tools from falling, and providing on-site transportation and construction tools 103 (such as self-propelled vehicles) walking. This will be explained in detail below.

When constructing the clean room waffle floor 101 , a large number of waffle buckets 1 are usually used. There are many types of known waffle buckets, and their structures are conventional techniques, so they will not be repeated here. During the forming process of the waffle floor 101 , the waffle bucket 1 may maintain a cylindrical shape, or may be slightly deformed. However, there are a lot of waffle holes 102 in the waffle floor 101 on the first floor. Therefore, it takes a lot of time to set up the corresponding round cover after determining whether it is deformed one by one. Round covers add a lot of cost. The main purpose of this creation is to facilitate the installation of a round cover plate in a waffle bucket that maintains a cylindrical shape or a slight deformation, and improves the conventional round cover plate 2 without ventilation rate.
