Description

Technical Field

[0001] The present invention relates to a clean room waffle bucket anti-falling device, and in particular to a clean room waffle bucket anti-falling device which can prevent objects such as on-site construction personnel and tools from falling while maintaining a predetermined ventilation rate, and provide on-site transportation and construction equipment (such as self-propelled vehicles) for walking. Background Art

[0002] like Fig. 9 As shown, a plurality of waffle holes 102 are provided on the waffle floor 101 of a current clean room to discharge pollutants such as dust and suspended particles in the air.

[0003] However, the number of waffle holes 102 on the clean room waffle floor 101 is large, and smaller people can be allowed to pass through, so there will be a problem of on-site construction workers, tools and other items falling. In addition, when it is necessary to provide on-site transportation and construction equipment 103 (such as a self-propelled vehicle) to travel, it is necessary to install a round cover plate 104 on the waffle hole 102 of the clean room waffle floor 101. However, the difference between the outer diameter of the existing round cover plate and the inner diameter of the waffle barrel should be controlled within a predetermined range, for example, the predetermined range should be controlled below 1 mm to reduce the sliding and vibration of the round cover plate. However, during the forming process of the waffle floor, the waffle barrel may maintain a cylindrical shape or may be slightly deformed. If the deformation of the waffle barrel exceeds the predetermined range, there will be a problem that the existing round cover plate is not easy to install. If various types of round covers are prepared to correspond to the deformation of the waffle barrel, a lot of costs will be added. In addition, the conventional circular cover plate 104 almost hermetically covers the waffle holes 102 of the clean room waffle floor 101 , causing the waffle holes 102 of the clean room waffle floor 101 to lose ventilation effect. Summary of the invention

[0004] The present invention is to solve the above-mentioned shortcomings. The present invention provides a clean room waffle bucket anti-fall device which can prevent objects such as on-site construction personnel and tools from falling while maintaining a predetermined ventilation rate, and provides on-site transportation and construction equipment (such as self-propelled vehicles) for walking.

[0005] The above-mentioned object of the present invention is achieved through the following technical solutions: a clean room waffle bucket anti-falling device, comprising a waffle bucket, which is arranged at a predetermined position when constructing a clean room waffle floor, and then is engaged in the clean room waffle floor to form a waffle hole that penetrates the clean room waffle floor; the inner side of the top of the waffle bucket has a step portion; and a circular cover plate, which is arranged on the top of the waffle bucket; the outer edge of the circular cover plate is provided with a lower flange; the bottom of the lower flange has at least one notch and the lower flange is placed on the step of the waffle bucket; and at least one fixed spring sheet, which has a fixed portion and an elastic deformation portion arranged on the outside of the fixed portion and extending upward and outward by a predetermined length; the fixed portion is fixedly arranged in the notch of the lower flange, so that the elastic deformation portion is arranged between the lower flange and the inner side of the waffle hole.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0027] like Figures 1 to 8As shown, a clean room waffle bucket anti-falling device 100 includes a waffle bucket 1, which is arranged at a predetermined position when constructing a clean room waffle floor 101, and then is engaged in the clean room waffle floor 101 to form a waffle hole 102 that penetrates the clean room waffle floor 101. The top inner side of the waffle bucket 1 has a step 11; and a circular cover plate 2 is arranged on the top of the waffle bucket 1; the outer edge of the circular cover plate 2 is provided with a lower flange 3; the bottom of the lower flange 3 has at least one notch 31 and the lower flange is placed on the step 11 of the waffle bucket 1; and at least one The fixing spring 4 has a fixing portion 41 and an elastic deformation portion 42 disposed outside the fixing portion and extending upward and outward by a predetermined length; the fixing portion 41 is fixedly disposed in the notch 31 of the lower flange 3, so that the elastic deformation portion 42 is disposed between the lower flange 3 and the inner side surface of the waffle barrel 1; with this structure, when the waffle barrel 1 is deformed, the elasticity of the elastic deformation portion 42 can be used to fix the circular cover plate 2 to the top of the waffle barrel 1, thereby preventing objects such as construction personnel and tools on site from falling, and providing on-site transportation and construction equipment 103 (such as a self-propelled vehicle) to travel. This will be described in detail below.

[0028] When constructing a clean room waffle floor 101, a large number of waffle barrels 1 are mostly used. There are many types of known waffle barrels, and their structures are prior art, so they will not be described in detail. During the molding process of the waffle floor 101, the waffle barrel 1 may maintain a cylindrical shape, or it may be slightly deformed. However, there will be a large number of waffle holes 102 in a layer of waffle floor 101, so if you want to distinguish whether they are deformed one by one and then set the corresponding round cover plates, it will not only take a lot of time, but also prepare various round cover plates corresponding to the deformation of the waffle barrels, which will increase a lot of costs. The main purpose of the present invention is to facilitate the setting of round cover plates in waffle barrels that maintain a cylindrical shape or have slight deformations, and to improve the existing round cover plates 2 without ventilation rate.

[0029] The circular cover plate 2 is disposed on the top of the waffle barrel 1. The outer edge of the circular cover plate 2 is provided with a lower flange 3; the bottom of the lower flange 3 has at least one notch 31, and the lower flange 3 is placed on the step 11 of the waffle barrel 1. In addition, the central portion of the bottom of the circular cover plate 2 may be provided with a plurality of ribs to increase the strength. Generally speaking, the difference between the outer diameter of the existing circular cover plate and the inner diameter of the waffle barrel can only be controlled within a very small predetermined range. The predetermined range may be less than 1 mm, and almost all of them make the outer diameter of the circular cover plate slightly smaller than the inner diameter of the waffle barrel to stabilize the circular cover plate and reduce the circular cover plate from sliding and vibrating in the waffle barrel. However, in the case where the waffle barrel may be deformed, there is often a problem that the existing circular cover plate cannot be placed in the waffle barrel. The circular cover plate 2 of the present invention is provided with at least one fixing spring 4, so that the circular cover plate 2 can be used for the waffle barrel 1 that maintains a cylindrical shape or has a slight deformation.

[0030] The fixing spring 4 has a fixing portion 41 and an elastic deformation portion 42 arranged outside the fixing portion 41 and extending upward and outward by a predetermined length; the fixing portion 41 is fixed to the notch 31 of the lower flange 3, so that the elastic deformation portion 42 is arranged between the lower flange 3 and the inner side surface of the waffle bucket 1; in this case, the difference between the outer diameter of the circular cover plate and the inner diameter of the top of the waffle bucket can be controlled within a relatively large predetermined range, and this predetermined range can be, for example but not limited to, less than 3 mm.

[0031] like Figure 5-6 As shown, the circular cover plate 2a may also have several through holes 21a to have a predetermined ventilation rate. The circular cover plate 2a may have several through holes 21a with a square cross section. Depending on the needs of the use, the number and aperture of the through holes 21a of the circular cover plate 2a can be adjusted, for example, the circular cover plate 2a has a ventilation rate of 55%-75%. By improving the circular cover plate 2a, it is possible to prevent items such as on-site construction personnel and tools from falling while maintaining a predetermined ventilation rate, and provide on-site transportation and construction equipment 103 (such as a self-propelled vehicle) to walk. In addition, by designing the circular cover plate 2a with through holes 21a, it is also convenient for users to remove the circular cover plate 2a from the waffle hole 102, so as to perform work such as repairing or replacing the circular cover plate 2a. Furthermore, the design of the circular cover plate 2a with through holes 21a can not only make the circular cover plate 2a have a ventilation rate, but also achieve the effect of reducing weight. In addition, an annular portion 22a may be provided around the circular cover plate 2a; the annular portion 22a is used to be clamped on the top of the waffle barrel 1, and there is no through hole on the annular portion 22a, which can increase the strength of the overall structure.

[0032] like Figure 7 As shown, the circular cover plate 2b may also have a plurality of through holes 21b with a circular cross section, the number and diameter of which can be adjusted according to the needs of the use, for example, the circular cover plate 2b has a ventilation rate of 25%-45%. In addition, among the through holes 21b of the circular cover plate 2b, at least one of the through holes 21b has a diameter larger than a finger, so that the user can easily take out the circular cover plate 2b.

[0033] like Figure 8 As shown, in addition to adjusting the cross-sectional shape, number and aperture of the through hole, the circular cover plate 2c may further include: an annular body 22c, disposed on the top of the waffle barrel; and a plurality of mutually intersecting support frames 23c, disposed inside the annular body; each support frame is spaced a predetermined distance apart to form a through hole 21c. The number of support frames 23c is not limited, and the number of support frames 23c may be adjusted according to the usage, thereby controlling the size of the through hole 21c. For example, two horizontal support frames and two vertical support frames may be provided on the annular body 22c, thereby enabling the circular cover plate 2c to have a ventilation rate of 80%-95%.

[0034] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
