Elevator shaft all-round protection facilities Technical Field

[0001] This invention relates to a construction site protection facility, specifically a comprehensive protection facility for elevator shafts. Prior Technology

[0002] An elevator shaft is a vertical space within a building specifically designed for elevator operation. It typically runs through multiple floors and houses the elevator car, guide rails, cables, and related mechanical equipment. Therefore, elevator shafts are a necessary space to reserve in a building.

[0003] Before a building is completed, elevator shafts typically lack proper doors and safety features, making them high-risk areas. These risks include: the danger of construction workers or others accidentally stepping into the shaft and falling – the most common and serious accident; insufficient temporary lighting increasing visibility and leading to accidents; and the risk of unauthorized personnel accidentally entering the shaft if adequate protective and warning signs are not provided. Therefore, without the installation of safety features and strengthened on-site management and personnel training during construction, accidents are highly likely to occur. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a comprehensive protective facility for elevator shafts that can improve construction site safety.

[0005] This novel all-around protective facility for elevator shafts is installed in an elevator shaft. The elevator shaft has a surrounding wall that encloses a passageway. The elevator shaft includes at least one transverse opening spanning the passageway and at least one longitudinal opening formed in the surrounding wall and spaced apart from the transverse opening. The all-around protective facility includes a transverse protective unit and a longitudinal protective unit. The transverse protective unit is used to cover the transverse opening and includes a plurality of fasteners fixed to the surrounding wall, a plurality of support frames attached to the fasteners, and a plurality of templates laid and fixed to the support frames. The longitudinal protective unit includes a rollable warning canvas disposed on the surrounding wall, which is used to cover the longitudinal opening.

[0006] Another technical aspect of this invention is that the template of the transverse protective unit is made of a light-transmitting material.

[0007] Another technical aspect of this invention is that the transverse protection unit further includes a grid layer disposed on the support frame, and the template is disposed and fixed on the grid layer.

[0008] Another technical aspect of this invention is that the lateral protection unit also includes a first fall protection net disposed below the support frame.

[0009] Another technical aspect of this invention is that the lateral protective unit also includes a second fall protection net located below the first fall protection net.

[0016] The advantage of this new invention is that, by fixing the fastener of the transverse protection unit to the surrounding wall, and then attaching the support frame to the fastener, and then setting and fixing the template, a stable and non-slip support platform is provided to block the transverse opening. At the same time, the longitudinal protection unit is used to block the longitudinal opening, which greatly improves the safety of the interior of the unfinished building and eliminates occupational hazards such as falls and rolls caused by the space of the elevator shaft. Simple Explanation of the Diagram

[0017] Figure 1 is a three-dimensional schematic diagram illustrating the installation location of a preferred embodiment of the new all-around elevator shaft protection facility, wherein the installation location is an elevator shaft; Figure 2 is a side view schematic diagram illustrating the structure of a transverse protective unit in this preferred embodiment; and Figure 3 is a front view schematic diagram illustrating the composition of a longitudinal protection unit in this preferred embodiment. Implementation

[0018] The features and technical content of this invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the accompanying drawings. Before proceeding with the detailed description, it should be noted that similar elements are represented by the same reference numerals. The directional terms used in the following embodiments, such as up, down, left, right, front, back, bottom, and top, are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0019] Referring to Figure 1, a preferred embodiment of the novel all-around protection facility for elevator shafts is shown. It is installed in an elevator shaft 1, wherein the elevator shaft 1 has a surrounding wall 11 that surrounds a passage 10. The elevator shaft 1 includes at least one transverse opening 12 spanning the passage 10, and at least one longitudinal opening 13 formed on the surrounding wall 11 and spaced apart from the transverse opening 12. Generally, the number of the transverse openings 12 and the longitudinal openings 13 corresponds to the number of floors in the building. Referring to Figures 2 and 3, the all-around protection facility for elevator shafts includes a transverse protection unit 2 (Figure 2) and a longitudinal protection unit 3 (Figure 3). In the following description, each transverse protection unit 2 is described in relation to a single transverse opening 12, and each longitudinal protection unit 3 is described in relation to a single longitudinal opening 13.

[0020] As shown in Figure 2, the lateral protective unit 2 is used to cover the lateral opening 12, and includes a plurality of fasteners 21 fixed to the surrounding wall 11, a plurality of support frames 22 attached to the fasteners 21, and a plurality of templates 23 laid and fixed to the support frames 22. Referring to Figure 3, the longitudinal protective unit 3 includes a rollable warning canvas 31 disposed on the surrounding wall 11, which is used to cover the longitudinal opening 13. Through the above design of the lateral protective unit 2, the lateral opening 12 can be basically blocked, and with the warning canvas 31 of the longitudinal protective unit 3, it also has the basic function of blocking the longitudinal opening 13.

[0021] Referring to Figure 2, it should be further explained that the locking fastener 21 of the transverse protective unit 2 is installed on the surrounding wall 11 either pre-embedded or post-installed. Regardless of whether it is pre-embedded or post-installed, the locking fastener 21 is stably attached to the surrounding wall 11 and will not easily move or fall off. The locking fastener 21 will be removed by cutting after construction is completed.

[0022] More specifically, the template 23 of the horizontal protective unit 2 is made of a light-transmitting material. This ensures sufficient light within the elevator shaft 1 when the building is not powered, improving visibility and safety for construction workers and avoiding operational risks in dimly lit environments. Furthermore, a grid layer 24 can be installed on the support frame 22. This grid layer 24 is attached to the support frame 22 using wire or other similar fixing methods. The template 23 is then positioned on this grid layer 24, further enhancing the stability of the template 23.

[0023] Furthermore, the transverse protective unit 2 also includes a first fall arrest net 25 disposed below the support frame 22, and a second fall arrest net 26 disposed below the first fall arrest net 25. In this preferred embodiment, the first fall arrest net 25 is a fixed fall arrest net disposed below the template 23, serving as a second layer of protection. The second fall arrest net 26 is installed after the template 23 is laid, and its main function is to allow construction workers to hook their safety ropes (main ropes) to the pre-installed O-rings when dismantling the template 23 and the support frame 22, ensuring the safety of the dismantling operation.

[0024] As shown in Figure 3, the longitudinal protection unit 3 also includes a fence 32 installed on the surrounding wall 11 and a toe board 33 installed on the surrounding wall 11. The warning canvas 31, the fence 32, and the toe board 33 are arranged from top to bottom to jointly cover the longitudinal opening 13. The warning canvas 31 blocks the upper half of the longitudinal opening 13 and is printed with warning text. The fence 32 blocks the lower half of the longitudinal opening 13 and has a lock 321 to prevent accidental opening. The toe board 33 serves to alert personnel to the possibility of entering the longitudinal opening 13. The longitudinal protection unit 3 also includes a platform structure calculation sheet and checklist 34, installed on the fence 32. The platform structure calculation sheet and checklist 34 are mainly used to ensure construction safety, structural stability, and management and usage. The platform structure calculation sheet is a technical document that performs structural and load analysis on construction platforms (such as construction scaffolding platforms, work platforms, etc.), with a focus on safety verification. The checklist is a site management tool used to track and control the platform's usage and safety status. Additionally, the longitudinal protection unit 3 includes a safety belt hook 35 installed on the surrounding wall 11 and a safety auxiliary handrail 36 installed on the surrounding wall 11. When construction workers need to enter the elevator shaft 1 through the longitudinal opening 13, they must hook their safety rope onto the safety belt hook 35 to provide a safety guarantee against falls, while the safety auxiliary handrail 36 provides a gripping function.

[0025] In summary, this novel all-around elevator shaft protection facility utilizes the locking fastener 21 of the horizontal protection unit 2, which is fixed to the surrounding wall 11. The support frame 22 is then attached to the locking fastener 21, and the template 23 is fixed in place, providing a stable and non-slip support platform to block the horizontal opening 12. Furthermore, the first fall protection net 25 and the second fall protection net 26 can be added as a second layer of protection. Simultaneously, the longitudinal protection unit 3 blocks the longitudinal opening 13, and the safety belt hook 35 and safety auxiliary handrail 36 are included, significantly improving the safety of unfinished building interiors and reducing occupational hazards such as falls and rolls caused by the elevator shaft space. This effectively achieves the purpose of this novel system.
