Description

Technical Field

[0001] This utility model relates to the technical field of building construction, specifically to an elevator shaft operating platform with a protective net for the opening. Background Technology

[0002] Elevator shafts are areas posing significant safety risks during construction. When installing formwork within elevator shafts during structural construction, an operating platform typically needs to be erected. Traditionally, this is done using coupler-type steel pipe scaffolding, and separate edge protection is required for the shaft opening. The erection of the operating platform is labor-intensive and often lacks standardization. In most projects, the elevator shaft protection is only installed after the formwork support system has been dismantled, resulting in installation lagging behind the structural construction progress. This necessitates an operating platform and protection method that is easy to use, cost-effective, and offers high safety standards. Utility Model Content

[0032] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0033] Example 1

[0034] like Figure 1 and Figure 2 As shown in the figure, an elevator shaft operating platform with a protective net for openings in this embodiment includes a platform plate 1, a support frame and a protective net for openings 2. The platform plate 1 is fixed to the top of the support frame and is arranged horizontally. One side of the support frame is the protective side for openings. The lower end of the protective side for openings is provided with a floor slab connection part 4. The protective net for openings 2 is fixed to the protective side for openings. The distance between the upper end of the protective net for openings 2 and the upper end of the support frame is no more than 20cm, which can prevent people or objects from falling.

[0035] like Figure 1As shown, in one specific embodiment, the platform plate 1 is a rectangular steel plate, and the mesh side length of the protective netting 2 is no greater than 40mm. The rectangular steel plate can be 3mm thick, which can effectively prevent objects from falling into the elevator shaft. The bottom of the rectangular steel plate can be supported by 8# channel steel to enhance the overall strength and stability of the top, ensuring that it will not easily deform or be damaged when subjected to large impact forces.

[0036] In this embodiment, the floor slab connection part 4 is used to connect with the floor slab fixing component installed on the floor slab 5 of the floor below the construction layer. The floor slab connection part 4 can be made of channel steel welded into a ┌-shaped structure, used to snap onto the edge of the floor slab 5 of the floor below the construction layer, and then connected and fixed to the floor slab fixing component using bolts. The floor slab connection part 4 can also be reinforced and fixed to the bracket by connecting rod 41.

[0037] This embodiment describes an elevator shaft operating platform with a protective netting at the opening. In actual construction, considering the space requirements for on-site operations, the platform's planar dimensions are reduced by 60mm compared to the elevator shaft opening. This ensures effective protection of the elevator shaft while providing necessary operating space for construction personnel. Specifically, three φ12mm steel bars are first welded securely to the support frame according to design requirements, effectively reinforcing the opening protection. After the steel bar welding is completed and inspected, the protective netting is installed, ensuring it is firmly installed without any loosening.

[0038] In this embodiment, the protective netting for the opening can be connected to the protective side of the opening by bolts or by welding. The entire support frame can be made of welded channel steel and can be a cubic structure or a triangular structure.

[0039] In this embodiment, an elevator shaft operating platform with a protective netting around the opening is used by installing floor slab fixing components at the marked position on the floor slab 5 one floor below the construction floor. Bolts are used to ensure a secure connection between the floor slab connection part 4 and the floor slab fixing components. A tower crane is used to hoist the elevator shaft operating platform to the construction floor 7, maintaining stability during the hoisting process to avoid shaking and collisions. After the elevator shaft operating platform is hoisted to the installation position, it is slowly lowered until the floor slab connection part 4 is aligned with the floor slab fixing components, and then connected with bolts. After connection, each connection is checked for security; any loose parts are reinforced immediately. The platform slab 1 is secured to the side wall of the construction floor 7 using wooden wedges 6. When the platform needs to be moved, the tower crane is used to hook the lifting ring and smoothly hoist it to the next construction floor 7. The above installation steps are repeated on each construction floor.

[0040] This embodiment describes an elevator shaft operating platform with a protective net for openings. By installing a protective net on the opening protection side of the support frame, it can provide safety protection for the openings near the edges, solving the problems of large safety hazards, low construction efficiency, and poor versatility in existing elevator shaft protection systems. This improves the safety, convenience, and economy of the elevator shaft operating platform and its protection.

[0041] Example 2

[0042] Based on Example 1, this example provides a preferred solution for protective netting at openings. For example... Figure 1 As shown, the protective netting 2 at the opening of the hole in this embodiment has multiple climbing holes 21. By creating multiple climbing holes in the protective netting, the netting can not only provide protection for the opening but also facilitate construction workers to climb the netting to the platform.

[0043] like Figure 1 As shown, a further embodiment of this problem involves arranging the multiple climbing holes 21 in a staggered manner from bottom to top. This staggered arrangement of the climbing holes from bottom to top facilitates climbing by construction workers.

[0044] like Figure 1 As shown, in a preferred embodiment, a horizontally arranged foot pedal 22 is provided at the bottom of the climbing hole 21, and the foot pedal 22 extends into the support. By providing the foot pedal, foot support can be provided for construction workers.

[0045] Optionally, the support frame's opening protection side or the opening protection net 2 may also be equipped with multiple climbing handles. These climbing handles facilitate climbing by construction workers holding onto them.

[0046] This embodiment features multiple climbing holes in the protective netting at the opening, allowing the netting to serve both as a protective barrier and a climbing ladder, making it highly convenient. To ensure climbing safety and the structural strength of the netting, the wires can be made of steel with a diameter of approximately 1-3 mm. Alternatively, horizontal reinforcing bars can be welded to the locations of the climbing holes, attaching them to the footboard and the uprights on both sides of the netting.

[0047] Example 3

[0048] Based on Embodiment 1 or Embodiment 2, this embodiment provides a preferred solution for the platform board 1. For example... Figure 1 and Figure 2 As shown, in this embodiment, a ring of channel steel 12 is fixed around the platform plate 1, with the open side of the channel steel 12 facing the platform plate 1. By fixing a ring of channel steel around the platform plate, the channel steel can serve as a kick plate, forming a construction boundary.

[0049] Example 4

[0050] Based on Embodiment 1, Embodiment 2, or Embodiment 3, this embodiment provides an optional solution for the platform plate 1. Multiple lifting rings 11 are fixed to the upper surface of the platform plate 1. By fixing multiple lifting rings to the platform plate, it is convenient to use a tower crane to lift the entire elevator shaft operating platform to the installation floor. Tower cranes facilitate the convenient transport of this operating platform, eliminating the need for repeated construction and dismantling on each floor, significantly improving construction efficiency and saving labor and material costs.

[0051] Specifically, four lifting rings 11 can be set at the four corners of the platform plate 1.

[0052] Example 5

[0053] Based on any of the above embodiments, this embodiment provides an alternative solution for the support. For example... Figure 1 and Figure 2 As shown, the support frame includes two uprights 3, two horizontal bars 31, two vertical bars 32, and two diagonal braces 33. Both uprights 3 are arranged vertically, and their upper and lower ends are fixedly connected by the two vertical bars 32. The two ends of each horizontal bar 31 are fixedly connected to the upper end of one upright 3 and the upper end of one diagonal brace 33, respectively. The lower end of each diagonal brace 33 is fixedly connected to the lower end of the upright 3. The horizontal bar 31, diagonal brace 33, and upright 3 together form a right-angled triangular support frame. The platform plate 1 is fixed to the two horizontal bars 31. The support frame, formed by the interconnection of horizontal bars, uprights, vertical bars, and diagonal braces, is a stable and reliable structure.

[0054] Preferred, such as Figure 1 and Figure 2 As shown, the support also includes a reinforcing frame 34 and a reinforcing rod 35. The reinforcing frame 34 is fixed at the middle position of the two uprights 3 and the two diagonal braces 33. The two ends of the reinforcing rod 35 are respectively fixed at the right angle position of the right-angled triangular support frame and at the middle position of the diagonal brace. By setting the reinforcing frame and the reinforcing rod, the structural strength of the support is increased.

[0055] In this embodiment, the uprights 3, horizontal bars 31, vertical bars 32, and diagonal braces 33 can all be made of channel steel. After cutting the channel steel to the required dimensions, the uprights 3, horizontal bars 31, and diagonal braces 33 are welded together sequentially to form a right-angled triangular support frame. Then, the two right-angled triangular support frames are welded and fixed together using the vertical bars, ensuring that the uprights are vertical, and the horizontal and vertical bars are horizontal and perpendicular to each other. The diagonal braces are arranged at an angle to reinforce the support. An optional design for the vertical bar 32 is that it can be a long, strip-shaped structure used as a kickboard.

[0056] In this embodiment, the uprights 3 are made of 16# channel steel and are vertically installed at the four corners and a suitable middle position of the platform. As the main load-bearing components, they withstand the pressure from the top structure and external loads. The diagonal braces 33 are made of 12# channel steel and connect the uprights and crossbars at a certain angle, providing reinforcement and improving the lateral force resistance of the support structure. The crossbars 31 are made of 16# channel steel and connect horizontally to the uprights, enhancing the lateral stability of the platform and forming a unified frame for the entire support structure. The platform is fixed to the floor slab using 16# channel steel, and wooden wedges 6 are used to further adjust the platform's levelness and stability.

[0057] Throughout the entire elevator shaft operating platform manufacturing process, each welding step undergoes quality inspection. This includes checking for full welds, absence of incomplete welds or gaps, measurement of component dimensions to ensure they meet design requirements, and inspection of the verticality, flatness, and overall stability of the supporting structure. Before installation, all components are inspected again to ensure no damage or deformation. All connections are checked, such as the connection between the floor slab and the floor slab fixings, the connections between the uprights and horizontal bars and diagonal braces, and the welds between the reinforcing bars and the uprights, ensuring secure and reliable connections. Protective components are also inspected, checking that the protective netting at openings is securely installed and undamaged. Before hoisting, the performance and safety of the tower crane are carefully checked to ensure the lifting equipment is intact. The tower crane hook is reliably connected to the lifting ring of the elevator shaft operating platform. During hoisting, a designated person directs the operation, maintaining platform stability and preventing swaying or collisions. When hoisting to the construction floor, the elevator shaft operating platform is slowly lowered until its bottom is precisely aligned with the floor slab fixings on the floor below the construction floor. The connection is then checked again for secureness. When a platform is needed, first loosen the connection between the platform and the floor slab fasteners, and use the same hoisting method to smoothly hoist the platform to the target floor. Repeat the installation and inspection process on the target floor.
