Description

Technical Field

[0001] This utility model belongs to the technical field of construction safety protection facilities, specifically relating to a prefabricated multi-layer folding hard isolation device for elevator shafts. Background Technology

[0002] Elevator shaft openings are a common type of opening on construction sites. Due to their large vertical height and open state, they are prone to safety accidents such as falls from heights and being struck by objects. Therefore, effective horizontal protection of elevator shaft openings is crucial to ensure the safety of construction workers and the smooth progress of construction.

[0003] Currently, there are two main types of protection for elevator shaft openings: One method uses steel profiles as supports, with steel pipe scaffolding erected on top. While this method provides some safety, it is cumbersome, requiring significant manpower and time for construction and dismantling. Furthermore, it presents high safety risks during construction and dismantling, potentially leading to injury or equipment damage. The other method involves pre-embedded steel mesh, with scaffolding laid on top. This method has poor impact resistance; the protective structure is easily damaged by significant impacts, failing to effectively guarantee construction safety. Additionally, the pre-embedded steel mesh needs to be cut later in construction, increasing labor costs and posing potential safety risks during the cutting process.

[0004] With the continuous development of construction technology, some new types of elevator shaft protection devices have been proposed, but these devices still have certain limitations. For example, the utility model patent with publication number CN222414164U discloses a prefabricated elevator shaft inner protective layer platform. This device is too bulky, inconvenient for on-site installation and reuse, its components are too scattered, its integration level is low, and it lacks secondary protection measures, resulting in insufficient safety assurance. Another example is the invention patent application with publication number CN119641117A, which discloses a foldable guardrail for use in elevator shafts and its usage method. However, the protection at the observation window position is inadequate, it does not consider the actual collision problems of hinged protective plates and steel zippers, and it lacks a second connecting device, resulting in poor impact resistance.

[0005] Therefore, developing a prefabricated multi-layer folding hard isolation device for elevator shafts to solve the problems of existing protective devices and improve the safety protection level of elevator shaft openings has important practical significance and broad application prospects. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies and provide a modular multi-layer folding hard isolation device for elevator shafts.

[0007] The specific technical solution adopted in this utility model is as follows:

[0008] This utility model provides a multi-layer folding hard isolation device for elevator shaft assembly, including a main frame, a limiter, a horizontal grid and a triangular grid; the main frame includes parallel longitudinal beams and a main frame transverse beam vertically fixed between the two longitudinal beams.

[0009] Several space frame buckles are fixed at intervals on the outer side of each main frame longitudinal beam. A space frame pin is set on one longitudinal side of the horizontal space frame, matching the number of space frame buckles on the main frame longitudinal beam. The space frame pin is inserted into the space frame buckle, so that the horizontal space frame rotates circumferentially about the main frame longitudinal beam. The top view of the horizontal space frame is a trapezoidal plane, and the hypotenuse of the horizontal space frame is hinged to the triangular space frame through a hinge.

[0010] Several limiters for locking the structural beams of the installation layer are provided at intervals on the main frame beams on one side of the main frame, and rope buckles for fixing the connecting structure are provided on the main frame beams on the other side; the other end of the connecting structure is connected to the structural wall of the upper layer of the installation layer.

[0011] Preferably, both the main frame crossbeams and the main frame longitudinal beams are made of square steel tubes and are fixed together as a whole by welding.

[0012] Preferably, the horizontal space frame and triangular space frame on the outer side of the main frame longitudinal beam are fully unfolded into a rectangular planar whole.

[0013] Preferably, the connection structure uses a steel wire rope or an adjustable steel rod.

[0014] Preferably, buffer pads are provided at the ends of the limiter and the longitudinal beams of the main frame; the buffer pads are made of rubber.

[0015] Preferably, the upper structural beam of the installation layer is provided with an open-type buckle with a pull ring, one end of the connecting structure is connected to the rope buckle on the main frame beam, and the other end is connected to the pull ring on the structural wall.

[0016] Preferably, the space frame buckle is fixed to the longitudinal beam of the main frame by welding or bolting.

[0017] Preferably, the space frame pin is fixed to one longitudinal side of the horizontal space frame by welding or bolting.

[0018] Preferably, the hinge is fixed between the inclined sides of the horizontal space frame and the triangular space frame by bolt connection.

[0019] Preferably, the outer frames of the horizontal space frame and the triangular space frame are both made of square steel pipes welded into a whole, with perforated mesh in the middle.

[0020] Compared with the prior art, this utility model has the following advantages:

[0021] (1) The folding hard isolation device provided by this utility model has good safety: 1) The inclined horizontal grid can effectively unload the falling object, and the rubber design at the end can achieve buffering, significantly reducing the impact risk of falling objects on personnel and equipment; 2) The main frame in this utility model can bear the force independently, which is convenient for protection. At the same time, the steel wire rope serves as a second safety insurance, further enhancing the safety of the device; 3) Operators do not need to enter the well to perform high-altitude operations. They only need to operate at the well side to complete the installation and dismantling, which effectively reduces the safety hazards of high-altitude operations.

[0022] (2) The device provided by this utility model adopts a prefabricated structure, which can be folded together in multiple layers, and has a high degree of integration. The device is small in size after folding, which is convenient for transportation and turnover during construction. At the same time, the prefabricated integrated design reduces the number of procedures and improves the installation efficiency. During the installation process, collisions may occur between the horizontal space frame and the structural wall. Through the secondary folding and unfolding of the triangular space frame, not only are collisions avoided, but flexible adjustment of the protection is also achieved to meet the needs of different construction scenarios.

[0023] (3) The installation of this device does not require drilling and chiseling. It only requires the use of open-type buckles inserted into the wall to fix the hanging point, which not only protects the wall structure, but also simplifies the installation process and improves the construction quality.

Detailed Implementation

[0031] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below. Technical features in various embodiments of this utility model can be combined appropriately without conflict.

[0032] As a preferred embodiment of this utility model, this embodiment provides a prefabricated multi-layer folding hard isolation device for elevator shafts. This folding hard isolation device is installed inside the elevator shaft to prevent building debris from entering the elevator shaft during construction, keeping the elevator shaft relatively clean and creating a good environment for subsequent elevator installation and commissioning.

[0033] like Figure 1 As shown, the folding rigid isolation device provided by this utility model includes a main frame 1, a limiter 2, a horizontal space frame 3, and a triangular space frame 4. The main frame 1 includes parallel longitudinal beams 102 and a main frame transverse beam 101 vertically fixed between two longitudinal beams 102. In this embodiment, both the transverse beam 101 and the longitudinal beams 102 are made of square steel tubing, and the four square steel tubing are welded together to form an integral main frame 1. It should be noted that those skilled in the art can also select other suitable profiles, such as channel steel or I-beams, according to actual working conditions.

[0034] like Figure 3 As shown, in this embodiment, several space frame buckles 7 are fixed at intervals on the outer side of each main frame longitudinal beam 102. The space frame buckles 7 can be made of round steel pipes cut into semi-circular steel sheets of a certain length, and are fixed to the main frame longitudinal beam 102 by welding. One longitudinal edge of the horizontal space frame 3 is fixed with space frame pins 8, matching the number of space frame buckles 7 on the main frame longitudinal beam 102, by welding. The space frame pins 8 are inserted into the space frame buckles 7, allowing the horizontal space frame 3 to rotate circumferentially about the main frame longitudinal beam 102. In this embodiment, the outer frames of the horizontal space frame 3 and the triangular space frame 4 are both made of square steel pipes welded together as a whole, with perforated mesh in the middle. Perforated mesh is a type of metal sheet, made by punching regularly arranged holes in the sheet. Perforated mesh is usually made of steel or aluminum plates and has a certain strength and toughness. The relatively small aperture of the perforated mesh effectively prevents debris, small tools, and other foreign objects from falling from the middle part of the isolation device during construction.

[0035] Several limiters 2 are spaced apart on the main frame beam 101 on one side of the main frame 1 to hold the structural beam 12 of the installation layer. In this embodiment, the limiters 2 are also made of square steel tubes and are set perpendicular to the main frame beam 101. It should be noted that the angle between the limiters 2 and the main frame beam 101 can also be adjusted according to the actual installation angle. On the other side of the main frame 1, the main frame beam 101 is provided with rope buckles 10 for fixing the connecting structure 5; the other end of the connecting structure 5 is connected to the structural wall 13 of the upper layer of the installation layer. In order to prevent the folding hard isolation device from damaging the structural wall, buffer pads are provided at the ends of the limiters 2 and the main frame longitudinal beam 102 in this embodiment. The buffer pads can be made of rubber. It should be noted that those skilled in the art can also use other elastic steel materials as needed.

[0036] like Figure 4 As shown, in this embodiment, the top view of the horizontal space frame 3 is a trapezoidal plane. The hypotenuse of the horizontal space frame 3 is hinged to the triangular space frame 4 via hinge 9. The hinge 9 is fixed between the hypotenuses of the horizontal space frame 3 and the triangular space frame 4 by bolt connection. When the horizontal space frame 3 and the triangular space frame 4 outside the main frame longitudinal beam 102 are fully unfolded, they form a rectangular plane as a whole, specifically as shown below. Figure 5 As shown.

[0037] An open-type clip 6 is fixed on the structural wall 13 above the installation layer of the elevator shaft where the folding rigid isolation device needs to be installed. A schematic diagram of the open-type clip 6 is shown below. Figure 6 As shown, the open-type buckle 6 is also provided with a pull ring 11 for fixing the connection structure 5. Those skilled in the art can select appropriate profiles to configure the open-type buckle 6 and pull ring 11 according to actual working conditions. Figure 2 As shown, one end of the connecting structure 5 is fixed to the pull ring 11 on the structural beam 12 of the upper layer of the installation layer, and the other end is fixed to the rope buckle 10 on the main frame crossbeam 101. In this embodiment, the connecting structure 5 directly uses a steel wire rope. It should be noted that the connecting structure 5 can also use an adjustable steel tie rod.

[0038] Next, this embodiment also provides a construction method for the above-mentioned prefabricated multi-layer folding hard isolation device for elevator shafts, the specific steps of which are as follows:

[0039] Step 1: Lowering the folded rigid isolation device

[0040] Secure one end of the wire rope to the rope buckle 10 on the main frame beam 101; then tighten the other end of the wire rope on the upper layer of the installation layer and lower the folded rigid isolation device from top to bottom to the installation layer. Maintain appropriate tension on the wire rope during the lowering process to prevent the device from shaking. After lowering, ensure that the limiter 2 at one end of the main frame longitudinal beam 102 is precisely engaged with the structural beam 12 on one side of the installation layer; continue lowering the folded rigid isolation device until the other end of the main frame longitudinal beam 102 abuts against the structural wall 13 of the installation layer. Ensure that the folded rigid isolation device rests stably against the structural wall of the elevator shaft.

[0041] Step 2: Deploying and Fixing the Main Frame

[0042] Unfold the horizontal space frames 3 on both sides of the main frame 1, so that they abut against the structural walls 13 on both sides of the installation layer; after the horizontal space frames 3 are stable against the wall, unfold the triangular space frames 4 on the inclined side of the horizontal space frames 3 to complete the full enclosure protection. Check the unfolded state of the horizontal space frames 3 and the triangular space frames 4 to ensure that they are in close contact with the structural walls.

[0043] Step 3: Secure the wire rope

[0044] Fix the open-type buckle 6 to the bottom of the structural wall 13 on the upper layer of the installation layer; fix the other end of the steel wire rope to the pull ring 11 on the open-type buckle 6, adjust the tension of the connecting structure 5 to make it taut, and complete the installation of the folding hard isolation device.

[0045] After construction is completed, the folding rigid isolation device needs to be removed. The removal process is carried out in reverse order of the construction steps. This construction process ensures that the installation and removal of the prefabricated multi-layer folding rigid isolation device in the elevator shaft are safe, efficient, and meet technical requirements.

[0046] The embodiments described above are merely preferred solutions of this utility model, and are not intended to limit the scope of this utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this utility model. Therefore, all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
