[0002] With the rapid development of modern construction industry, higher requirements are put forward for the safety, efficiency and quality of construction. In complex projects such as high-rise buildings and large public facilities, there are often horizontal openings such as material transfer openings and wire laying openings on the construction operation layer. In order to effectively prevent construction personnel or objects from accidentally falling into the openings, the construction protection of horizontal openings is particularly important. Traditional protective measures often have many shortcomings. For example, the installation and disassembly process of traditional protective facilities is usually complicated and time-consuming, lacks sufficient strength and stability, and protruding handles are easy to trip, resulting in poor protection effect, low construction efficiency and high maintenance cost. Therefore, finding a more efficient, safe and economical horizontal opening protection technology has become an urgent need in the industry. Utility Model Content

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0023] As shown in the figure, a working layer horizontal hole protection device described in the utility model includes an upper cover plate 1 and a lower frame 2. The size of the upper cover plate 1 is larger than the size of the horizontal hole. Symmetrical semicircular holes 3 are opened in the middle of the upper cover plate 1. The slats left between the symmetrical semicircular holes 3 serve as handles 4. The lower frame 2 is arranged on the back of the upper cover plate 1. The size of the lower frame 2 is consistent with the size of the horizontal hole to be protected. The lower frame 2 is a frame structure vertically surrounded by aluminum alloy square tubes.

[0024] The utility model discloses a protective device for a horizontal opening of a working layer, wherein a lower frame 2 is a frame structure formed by four aluminum alloy square tubes in a vertical direction, the lower frame 2 is 50 mm high, and a steel plate is welded on the upper portion as an upper cover plate 1, and two handles 4 are made on the upper cover plate 1 (semicircular holes are directly opened without coming up). When in use, the handles 4 are held, and the lower frame 2 is directly clamped in the opening position so that it fits tightly with the edge of the opening. The length and width of the upper cover plate 1 are larger than the size of the opening, so that it can effectively cover the horizontal opening of the working layer, thereby improving the construction safety of the working layer.

[0025] Since the handle 4 is directly opened on the upper cover plate 1 without any protruding part, people will not trip when walking on it.

[0026] The device is provided with a reinforcing tube 7 in the middle of the lower frame 2, which is welded to the lower frame 2 into a whole, thereby increasing the strength and ensuring that the upper cover plate 1 will not bend or deform.

[0027] The utility model is provided with a semicircular bracket 5 below the handle 4, which can effectively prevent impurities and air from entering the interior of the concrete during the concrete pouring process, thereby ensuring the purity and final quality of the concrete.

[0028] In order to prevent the operator from stepping on the handle 4 and causing it to deform, the utility model provides a support rod 6 below the handle 4 and fixedly connected with the bracket 5 to increase stability.

[0029] The utility model provides a chamfer 8 on the lower edge of the lower frame 2 to facilitate insertion into the horizontal hole.

[0030] In addition, the utility model is provided with a connecting hole 9 on the edge of the upper cover plate 1. After installation, a suitable fixing member or connecting member is used to firmly fix the upper cover plate 1 on the hole to prevent it from shifting or falling off during use.

[0031] The device has light weight, strong bearing capacity, convenient construction and good stability, which can effectively prevent people or objects from accidentally falling into the hole and improve safety during the construction process. It is also easy to disassemble and can be reused, which not only improves construction efficiency but also saves materials and costs.

[0032] Since the lower frame 2 can fit closely to the edge of the hole, its stability and safety during the construction process are ensured; this stable protective structure can effectively prevent damage and deformation of the edge of the hole, protect the safety of construction workers, and also help keep the hole clean and beautiful.

[0033] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
