[0066] Optionally, the diamond pattern plate, the flat bean pattern plate, etc. The surface of the pattern plate has a convex rib structure, which can increase the friction and play a role in preventing slipping.

[0067] Convex rib structure: The convex rib structure on the surface of the pedal panel 112 can effectively prevent workers from slipping when walking on the pedal panel 112, protecting the safety of workers when inspecting or maintaining the roof unit 11.

[0068] The embodiment is as shown in the figure. Figure 2 Preferably, the adjacent connecting ends of the plurality of roof units 11 are provided with a complementary slot 14.

[0069] The complementary slot 14 is arranged at the connecting end of the adjacent roof panel unit 11, and the complementary slot 14 is arranged at the four corners of the roof panel unit 11. The role of the complementary slot 14 is to form a certain gap at the corner when the plurality of roof panel units 11 are connected, which facilitates the avoidance of the column or other obstacles on the construction platform, so that the roof panel unit 11 can be more flexibly arranged to adapt to the construction platform of different shapes.

[0070] Preferably, the complementary slot 14 is a square slot.

[0081] The upper surface of the roof panel unit is provided with a plurality of reinforcing ribs, which are parallel to each other and extend along the length direction (or width direction) of the roof panel unit. The parallel arrangement of the reinforcing ribs can effectively improve the bending strength and rigidity of the roof panel unit in the direction perpendicular to the reinforcing ribs. When the ceiling bears a vertical load (such as a falling object impact), the reinforcing ribs can disperse and transfer the load, preventing the roof panel unit from deforming or being damaged. The parallel arrangement of the reinforcing ribs also facilitates the processing and installation of the roof panel unit, and the structure is relatively simple. The perpendicular arrangement of the reinforcing ribs can improve the bending strength and rigidity of the roof panel unit in all directions, and can effectively support and disperse the load from any direction. The grid-like reinforcing rib structure has higher overall strength and stability, and can better cope with complex stress conditions and harsh construction environments.

[0082] Preferably, Q235 steel is used, which has good strength, rigidity and economy, and can meet the structural strength and safety performance requirements of the protective ceiling.

[0083] In summary, the utility model provides a protective ceiling suitable for right-angle door opening construction platform. The protective ceiling is composed of a roof panel assembly, a support assembly and an adjusting assembly. The roof panel assembly provides effective top protection to prevent falling objects from high altitude, and the reinforcing ribs further improve the strength and carrying capacity of the roof panel. The support assembly ensures the stable support of the protective ceiling and connects with the construction platform guardrail through the brace to enhance the stability of the overall structure. The adjusting assembly realizes the flexible adjustment of the height of the protective ceiling, so that it can adapt to the requirements of construction platforms of different heights. The preferred structural design, such as the laminated roof panel unit, metal material and corrosion-resistant coating, patterned tread panel, make-up slot and make-up plate, and the application of square tube material, further improves the protection performance and safety performance of the protective ceiling.

[0084] The working principle of the protective ceiling suitable for right-angle door opening construction platform is as follows:

[0085] 1. The protection principle of the roof panel assembly:

[0086] A plurality of top plate units are arranged continuously along the top edge of the construction platform to form a complete roof covering structure, like a solid roof, directly blocking objects that may fall from the air, such as tools, building materials or debris, etc., to provide safety protection. A plurality of reinforcing ribs on the upper surface of the top plate unit, like building columns, enhance the structural strength and rigidity of the top plate unit. When the roof is impacted by falling objects, the reinforcing ribs can disperse and absorb the impact force, preventing the top plate unit from deforming or breaking, and ensuring the integrity and protection effect of the roof structure. The top plate crossbar located at the outer edge of the top plate unit connects a plurality of top plate units into a whole and is connected with the support assembly and the adjustment assembly. The top plate crossbar, like a frame beam, improves the overall rigidity and stability of the top plate assembly, enabling it to withstand greater loads and impacts, and providing a stable connection foundation for subsequent support and adjustment.

[0087] 2. The stability support principle of the support assembly:

[0088] The lower vertical rod directly bears the gravity and external impact force from the top plate assembly. The lower crossbar connects the two lower vertical rods together to form a stable bottom support structure, ensuring the overall stability of the protective roof and preventing it from tipping over or swaying. The threaded connection between the lower vertical rod and the lower crossbar ensures the connection strength, while facilitating installation and disassembly. The first end of the brace is threadedly connected with the top plate crossbar of the top plate assembly, and the second end of the brace is firmly connected with the guardrail of the construction platform through the connecting part. Connecting the protective roof with the main structure of the construction platform into a whole effectively enhances the lateral stability of the protective roof, resisting the risk of overturning caused by wind or other external factors.

[0089] 3. The height adjustment principle of the adjustment assembly: The lower end of the movable vertical rod is sleeved on the upper end of the lower vertical rod to form a telescopic sleeve structure. The movable vertical rod, like a telescopic rod, can slide up and down inside the lower vertical rod, thereby changing the overall height of the protective roof. A plurality of through holes are provided on the movable vertical rod and the lower vertical rod for height adjustment. By inserting a locking pin into the selected through hole, the position of the movable vertical rod relative to the lower vertical rod can be fixed, and the protective roof can be locked at the desired height. Different heights of through holes are combined to realize stepwise adjustment of the height of the protective roof to adapt to different heights of the construction platform or operation requirements.

[0090] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the scope of the technical solution of the present application.
