Description

Technical Field

[0001] This application relates to the field of building construction safety protection technology, and in particular to a reusable modular elevator shaft protection system. Background Technology

[0002] In high-rise building construction, elevator shaft openings are of paramount importance for safety protection. Currently, the common methods are to erect guardrails using steel pipes with fasteners, or to embed components in the wall and then weld protective netting. These traditional methods have significant drawbacks: First, steel pipe erection is inefficient and unstable, and its removal leaves numerous bolt holes or weld points on the wall, compromising structural integrity and requiring costly repairs. Second, traditional protective devices are mostly rigid structures, unable to flexibly adapt to openings of different sizes, resulting in poor reusability. Finally, their protective function is limited, with limited overall stability and impact resistance.

[0003] Therefore, there is an urgent need in this field for an elevator shaft protection solution that can provide robust and reliable protection without damaging the building structure, can be quickly installed and disassembled and can be efficiently recycled, and can intelligently adapt to different working conditions. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a reusable modular elevator shaft protection system and method. This system achieves damage-free installation, excellent stability, and wide adaptability through a unique oblique clamping mechanical design and modular flexible connections.

[0005] The technical solutions provided in the embodiments of this specification are as follows: In a first aspect, this utility model provides a reusable modular elevator shaft protection system, comprising: A core protection module consists of at least two protection units connected in series by a flexible connector, the flexible connector allowing relative rotation between adjacent protection units within a certain angular range; At least one adjustable lateral anchoring mechanism, the anchoring mechanism comprising: A constraint device fixed to the outermost protective unit of the core protection module, the constraint device comprising a pressure-bearing plate parallel to the wall and a fastening nut detachably connected to the core protection module; An anchoring tie plate pre-embedded in the concrete side wall of the elevator shaft opening; A fastening bolt that passes through the fastening nut and is screwed onto the anchoring tab; The pressure-bearing support plate is not parallel to the plane of the core protection module, so that when the fastening bolts are tightened, the pressure-bearing support plate generates a pressing force perpendicular to the wall surface, thereby pressing the core protection module tightly against the front of the elevator shaft opening.

[0006] Furthermore, the side of the pressure-bearing plate opposite to the fastening nut is inclined, and the included angle α between it and the plane of the core protection module is 85°≤α<90° or 90°<α≤95°.

[0007] Furthermore, the restraint device also includes a reinforcing rib plate that is welded perpendicularly to the pressure-bearing support plate, and the reinforcing rib plate is also welded to the frame of the protective unit.

[0008] Furthermore, the bottom edge of the protective unit is bent inward to form an integrated water-blocking edge.

[0009] Furthermore, the protective unit is provided with T-shaped grooves on both sides, and the fastening nut is provided with a T-shaped slider that matches the T-shaped groove on one side.

[0010] Furthermore, the flexible connector is a double-hinged metal louver chain or a high-strength engineering plastic hinge.

[0011] Secondly, this utility model also provides a method for installing the above-mentioned reusable modular elevator shaft protection system, comprising the following steps: S1: Before pouring the concrete for the side wall of the elevator shaft, locate the anchoring tie plate according to the opening size and pre-embed it in the template; S2: After the concrete formwork is removed, place the connected core protection modules in front of the elevator shaft opening; S3: Align the constraint device of the adjustable lateral anchoring mechanism with the position of the anchoring tab; S4: Pass the fastening bolt through the fastening nut and screw it onto the anchoring tab; S5: Continuously tighten the fastening bolts, and use the angle between the pressure plate and the wall to stably press the core protection module into the set position.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Revolutionary mechanical fixing principle: By designing the pressure-bearing plate to be non-parallel to the protective surface, a compressive force is generated when the bolts are tightened, which pushes the entire protective system towards the wall, creating a "tightening as it is pulled" mechanical effect. This greatly enhances the overall stability and impact resistance of the system, solving the problems of insecure fixing and easy shaking in traditional methods.

[0013] 2. Truly zero-destruction and highly recyclable: All stress points are based on pre-embedded anchoring tabs, requiring zero drilling and welding to the main structure. Dismantling only requires removing the bolts and cutting off and grinding the exposed tabs. The main system (protective modules, restraint devices, bolts) can be 100% recycled, making it economical and environmentally friendly.

[0014] 3. Excellent adaptability and installation efficiency: The modular design and flexible connections allow the system to adapt flexibly to elevator shaft openings of different widths and layouts, making it as easy to unfold and adjust as a "curtain." Installation requires no open flame or professional electrician; it can be completed quickly with just a wrench, significantly improving efficiency.

[0015] 4. Functional integration and enhanced safety: The one-piece molded water barrier effectively prevents water from flowing into the shaft; the magnetic warning light strip provides proactive safety warnings, improving the intelligence level of the protection system and nighttime safety.

[0016] 5. Robust and durable structure: The added reinforcing ribs ensure the rigidity and durability of the restraint device under complex stress; the pull-out resistance design on the anchoring tabs ensures the reliability of the embedded parts and eliminates the possibility of detachment at the source.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0024] This specification provides an example of a reusable modular elevator shaft protection system. Please refer to [link / reference]. Figures 1-3 As shown, it mainly consists of a core protection module and at least one set (usually two sets, left and right) of adjustable lateral anchoring mechanisms.

[0025] The core protection module consists of two or more protection units 1 connected in series by flexible connectors 5. In this embodiment, the frame 12 of the protection unit 1 is welded from 40mm×40mm square steel pipes, and the interior is fully covered with steel wire mesh 11. The flexible connector 5 is a double-hinged metal louver, which allows relative angular rotation between adjacent protection units 1. This allows the entire protection surface to adapt to uneven wall surfaces during installation, or to be folded during storage and transportation, saving space.

[0026] At the bottom of each protective unit 1, its frame 12 is bent inward and welded to seal, forming an integrated water barrier. This water barrier not only effectively prevents floor maintenance water, rainwater, etc. from flowing into the elevator shaft, but its integrated structure is also more robust and aesthetically pleasing than toe boards added later.

[0027] The adjustable lateral anchoring mechanism mainly includes a restraint device 2, an anchoring tab 3, and a fastening bolt 4. The restraint device 2 is welded to the frame 12 of the outermost protective unit 1 of the core protective module. The restraint device 2 consists of a pressure-bearing plate 21 parallel to the wall surface 6, a fastening nut 22 detachably connected to the core protective module, and a reinforcing rib connecting the pressure-bearing plate 21 and the frame 12. Crucially, the installation posture of the entire restraint device 2 results in an angle α between the pressure-bearing plate 21 and the plane of the core protective module. In this embodiment, this angle α is set to 87°. This subtle angle is the source of the compressive force. For further explanation, please refer to [link to relevant documentation]. Figure 4 and Figure 5 As shown, the protective unit has T-shaped grooves 13 on both sides, and a T-shaped slider 23 matching the T-shaped groove is provided on one side of the fastening nut. In use, the fastening nut is slid into the T-shaped groove via the T-shaped slider, achieving a sliding connection with the protective unit. When the bolt is tightened, the protective unit can move up and down relative to the fastening nut, achieving a tight fit between the protective unit and the wall. The anchoring tie 3 is a 4mm thick steel plate with multiple pull-out ribs stamped on its embedded end to enhance its anchoring force in the concrete. During the structural construction phase, it is precisely embedded in the walls on both sides of the elevator shaft opening.

[0028] During installation, the assembled core protection module is placed upright at the elevator shaft opening, with its side restraint device 2 aligned with the pre-embedded anchoring tab 3. Then, a fastening bolt 4 (such as an M8 bolt) is passed through the fastening nut 22 and screwed into the threaded hole of the anchoring tab 3. As the bolt 4 is continuously tightened, due to the included angle α, the axial tensile force F of the bolt is decomposed into two components: one parallel to the wall and one perpendicular to the wall and pointing towards it. This pressure component firmly "presses" the entire core protection module against the wall at the elevator shaft opening, further providing installation stability.

[0029] In addition, a solar-powered warning light strip (not shown in the picture) is magnetically attached to the top frame of the core protection module. It can automatically flash in dim light, serving as a good warning.

[0030] Removal is a completely reversible process: unscrew bolt 4 and retract the protective system. Exposed ends of anchoring tabs 3 on the wall can be cut off and smoothed using an angle grinder without damaging the structure.

[0031] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0032] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
