Description

Technical Field

[0001] The utility model belongs to a safety auxiliary tool for a construction site, which is a rotatable driving protection cover plate at an opening of a waffle plate floor and a protection structure thereof. Background Art

[0002] In recent years, the chip manufacturing industry has rapidly grown, and the proportion of modern large-scale, high-tech integrated circuit production plant construction projects in the construction market has been increasing. Due to the specialized nature of production work in modern large-scale, high-tech electronics plants, high ventilation performance is often required. Waffle panels are a structure tailored to meet this requirement. Due to their unique perforated structure, waffle panels meet both the structural requirements of the plant and the ventilation requirements, making them widely used in various large-scale, high-tech electronics plant construction projects.

[0003] Waffle slabs are formed by regularly arranged holes in the floor. Due to their unique structure, they significantly impact on-site construction. These holes force construction workers to divert their attention to avoid the holes, impacting efficiency and even safety. The holes also restrict the stacking of materials, potentially causing them to fall through the holes to the lower floor, causing damage or even injury. The holes also complicate the use of construction equipment, prohibiting the use of forklifts, lift trucks, and other construction vehicles. Without these tools, many processes cannot proceed normally.

[0004] When working on waffle slabs, the holes need to be sealed. The traditional way to seal holes is to cover them with steel plates. This method is relatively simple, but it also has obvious drawbacks:

[0005] 1. Ordinary steel plates are used to directly cover the opening. Due to the lack of a fixing device, the steel plates are unstable and prone to slipping during construction, exposing the opening and affecting the safety and stability of the vehicle operation above it, resulting in poor covering effect.

[0006] Second, when using integral steel plates for covering, although it can solve the problems of covering stability and driving operation safety, the opening and the plate surface are covered together, the covering area is large, and the cost is high; during use, due to the load of construction materials and construction equipment, large-area covering steel plates are prone to deformation and warping, and the material loss rate is high.

[0007] Therefore, how to design a fixed, turnover, adjustable, low-loss, high-strength modern clean workshop waffle plate driving operation protective steel cover has become our current problem to be solved. Utility Model Content

[0008] The purpose of the utility model is to provide a revolving driving protection cover plate and its protection structure at the opening of the waffle plate floor, and to solve the technical problems that when the existing waffle plate is used to protect the hole, ordinary block steel plates are used to directly cover the hole, which has no fixing device, the steel plate is unstable, and it is easy to slip, causing the opening to be exposed, affecting the safety and stability of the vehicle operation on it, and the covering effect is poor; and to solve the technical problems that the use of integral steel plates for covering requires covering the opening and the plate surface together, the covering area is large, the cost is high, the load is large during use, and a large area of ​​the covered steel plate is prone to deformation and warping, and the material loss rate is high.

The keel transverse groove 223 and the keel bolt hole 224 are centered and arranged at the same height in the height direction of the slide plate 221.

[0047] The removable connector 4 is a bolt, including a first bolt 41 and a second bolt 42. The rail's transverse groove 213 is aligned front-to-back with the keel's bolt hole 224 and is removably connected via the first bolt 41. The rail's bolt hole 214 is aligned front-to-back with the keel's transverse groove 223 and is removably connected via the second bolt 42. The two bolts secure the top keel 22 to the forked center rail keel 21 at two points, creating a more secure connection. The top keel 22 can be fixed between the edge of the opening and the forked center rail keel 21, thereby securing the steel cover in place and preventing it from slipping during vehicle operation, significantly improving safety.

[0048] The plate length of the slide plate 221 is the same as that of the fixed fork rail plate 211, both of which are rectangular plates and have the same plate length.
