Description

Technical Field

[0001] This application relates to the field of building engineering technology, and in particular to a building safety railing. Background Technology

[0002] With the development of technology in the field of construction safety protection, construction safety railing technology has emerged. This technology usually adopts a single piece of steel or aluminum alloy structure, with fixed posts on both sides, to ensure the safety of the construction site. Traditional construction safety railings are difficult to adapt to the uneven ground of the construction site.

[0003] In related technologies, height-adjustable column structures are typically used, and anchor bolts or pads are used to help fix them to the uneven ground to alleviate the tilting problem caused by uneven terrain, thereby ensuring that multiple guardrails can be smoothly connected.

[0004] However, due to the rigid design of a single guardrail, the aforementioned guardrails can only adapt to local height adjustments when laid continuously, making them difficult to use on the overall undulations of complex terrain. When laying guardrails continuously, each section of guardrail needs to be adjusted one by one; otherwise, the guardrails cannot be connected smoothly, which is time-consuming and labor-intensive, and may also lead to overall tilting or gaps due to not fitting the ground. Utility Model Content

[0005] Therefore, it is necessary to provide a construction safety railing that can quickly adapt to complex terrain, reduce manual adjustments, ensure the smooth connection of multiple construction safety railings, and is suitable for large-scale construction in sandy or uneven construction site environments.

[0006] A construction safety railing, comprising:

[0007] First protective section;

[0008] The second protective section is set up sequentially along the extension direction of the building's protective railing, along with the first protective section.

[0009] A universal joint device is located between the first protective section and the second protective section. The universal joint device includes a cross-shaped connecting frame and at least two Y-shaped swing frames. One end of one Y-shaped swing frame is connected to the first protective section, and the other two ends of the Y-shaped swing frame are pivotally connected to the opposite ends of the cross-shaped connecting frame. One end of the other Y-shaped swing frame is connected to the second protective section, and the other two ends of the Y-shaped swing frame are pivotally connected to the other opposite ends of the cross-shaped connecting frame.

[0010] In one embodiment, multiple universal joint devices are provided, and the multiple universal joint devices are arranged at intervals along the direction of gravity.

[0011] In one embodiment, the first protective section is provided with a first connecting groove, and one end of the Y-shaped swing frame connected to the first protective section is located in the first connecting groove.

[0012] The second protective section has a second connecting groove, and one end of the Y-shaped swing frame that is connected to the second protective section is located in the second connecting groove.

[0013] In one embodiment, one end of one of the Y-shaped swing frames is detachably connected to the first protective section;

[0014] One end of another Y-shaped swing frame is detachably connected to the second protective section.

[0015] In one embodiment, a plurality of insertable blocks are provided on the side of the first protective section away from the second protective section; a plurality of plug-in blocks are provided on the side of the second protective section away from the first protective section; the insertable blocks of the building protective railing are used to connect to the plug-in blocks of another building protective railing; the plug-in blocks of the building protective railing are used to connect to the insertable blocks of another building protective railing.

[0016] In one embodiment, one of the inserted block and the connecting block is provided with a magnet, and the other is provided with a magnetic attraction element; the magnet of the building safety railing is used to attract the magnetic attraction element of the other building safety railing; the magnetic attraction element of the building safety railing is used to attract the magnet of the other building safety railing.

[0017] In one embodiment, the bottom surface of the first protective section is provided with at least two first insert rods; the bottom surface of the second protective section is provided with at least two second insert rods.

[0018] In one embodiment, the bottom of the first insert is a pointed structure; the bottom of the second insert is a pointed structure.

[0019] In one embodiment, the first protective section has a first cavity containing a plurality of first springs, the two ends of which are respectively connected to the horizontal opposite sides of the first protective section, and the axial direction of the springs is parallel to the wall thickness direction of the building guardrail.

[0020] The second protective section has a second cavity containing multiple second springs. The two ends of the second springs are connected to the horizontal opposite sides of the second protective section, and the axial direction of the second springs is parallel to the wall thickness direction of the building's protective railing.

[0021] In one embodiment, the insert block has a U-shaped structure, and the slot of the insert block faces the height direction; the plug block has a U-shaped portion;

[0022] The U-shaped structure of a building safety railing is used to connect the U-shaped part of another building safety railing.

[0023] The U-shaped section of a building safety railing is used to connect to the U-shaped structure of another building safety railing.

[0024] Compared with existing technologies, the beneficial effects of this utility model on the aforementioned construction safety railings are as follows:

[0025] 1. The first protective section, as the starting module of the building safety railing, can provide a stable positioning point for the second protective section, laying the foundation for the flexible placement and extension of subsequent modules.

[0026] The second protective section, along with the first protective section, is set sequentially along the extension direction of the building's protective railing. As a continuation module of the first protective section, it can flexibly adjust its angle according to changes in terrain, including the horizontal angle due to uneven terrain, to ensure the overall continuity of the building's protective railing and its conformity to changes in the ground, as well as to change the placement angle and direction of the building's protective railing according to the specific area or edge line of the construction site.

[0027] 2. A universal joint device, located between the first and second protective sections, includes a cross-shaped connecting frame and at least two Y-shaped swing frames. The cross-shaped connecting frame, as the core structure of the universal joint, provides multi-directional rotational adjustment, enabling flexible connection between the protective sections. This ensures the adaptability of the construction safety railing in complex terrain, improves its stability, and prevents it from tipping over or becoming unstable. One end of one Y-shaped swing frame is connected to the first protective section, and its other two ends are pivotally connected to opposite ends of the cross-shaped connecting frame, allowing for flexible swinging of the first protective section. One end of the other Y-shaped swing frame is connected to the second protective section, and its other two ends are pivotally connected to opposite ends of the cross-shaped connecting frame, also allowing for flexible swinging of the second protective section. The Y-shaped swing frames provide multi-point support, ensuring a smooth transition between the first and second protective sections.

[0028] 3. The flexible parts of the universal joint device enable the construction project's protective railing to quickly adapt to sandy or undulating terrain, avoiding the problems of suspension or tilting that occur with traditional protective railings. On-site construction only requires the installation of the first protective section, and the second protective section can be installed by adjusting the angle through the universal joint device. There is no need to measure the ground or make repeated adjustments, which greatly simplifies the installation process. Attached Figure Description

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] See Figures 1-5 The diagram shown is a structural schematic of a building safety railing in one embodiment of this application. The building safety railing provided in one embodiment of this application includes: a first protective section 1, a second protective section 2, and a universal joint device 3.

[0042] The first protective section 1 and the second protective section 2 can be either protective panels or protective fences. Multiple construction protective fences are set up in sequence to isolate areas at the construction site and protect construction safety.

[0043] The second protective section 2 and the first protective section 1 are sequentially installed along the extension direction of the construction safety railing. Both sections can be made of sturdy metal materials, possessing sufficient strength and rigidity to withstand external impacts. Specifically, the first and second protective sections 1 and 2 can be manufactured as cuboids of suitable length, adapting to the undulations of common construction terrain. Their length aligns with the extension direction of the construction safety railing, while their height and width meet protection standards and practical application scenarios, ensuring effective prevention of personnel and objects from entering hazardous areas while facilitating installation and use.

[0044] See Figure 3 and Figure 4 The universal joint device 3 is located between the first protective section 1 and the second protective section 2, forming a unified whole between them, and can be flexibly adjusted at multiple angles according to the terrain. The universal joint device 3 includes a cross-shaped connecting frame 31 and at least two Y-shaped swing frames 32. The cross-shaped connecting frame 31 is similar to the shape of a "+", and its four ends are pivotally connected to the Y-shaped swing frames 32. One end of one of the Y-shaped swing frames 32 is connected to the first protective section 1, and the other two ends of the Y-shaped swing frame 32 are pivotally connected to opposite ends of the cross-shaped connecting frame 31, allowing the Y-shaped swing frame 32 to rotate freely within a certain range around the pivot. One end of another Y-shaped swing frame 32 is connected to the second protective section 2, and the other two ends of the Y-shaped swing frame 32 are pivotally connected to the other opposite ends of the cross-shaped connecting frame 31, thereby realizing the multi-angle flexible connection of the first protective section 1 and the second protective section 2. Indicatively, when encountering terrain undulations or needing to turn at the construction site, the Y-shaped swing frame 32 can adjust its angle according to the actual situation to ensure the continuity and adaptability of the construction project's protective railing.

[0045] The first protective section 1, as the starting module of the building safety railing, can provide a stable positioning point for the second protective section 2, laying the foundation for the flexible placement and extension of subsequent modules.

[0046] The second protective section 2 is set sequentially along the extension direction of the first protective section 1. As a continuation module of the first protective section 1, it can flexibly adjust its angle according to changes in terrain, including the horizontal angle due to uneven terrain, to ensure the overall continuity of the construction project's protective railing and its conformity to changes in ground, as well as to change the placement angle and direction of the construction project's protective railing according to the specific area or edge line of the construction site.

[0047] The universal joint device 3 is located between the first protective section 1 and the second protective section 2. The universal joint device 3 includes a cross-shaped connecting frame 31 and at least two Y-shaped swing frames 32. The cross-shaped connecting frame 31, as the core structure of the universal joint, provides multi-directional rotational adjustment, enabling flexible connection between the protective sections. This ensures the adaptability of the construction project's protective railing in complex terrain, improves its stability, and prevents it from tilting or becoming unstable. One end of one Y-shaped swing frame 32 is connected to the first protective section 1, and its other two ends are pivotally connected to opposite ends of the cross-shaped connecting frame 31, enabling flexible swinging of the first protective section. One end of the other Y-shaped swing frame 32 is connected to the second protective section 2, and its other two ends are pivotally connected to opposite ends of the cross-shaped connecting frame 31, enabling flexible swinging of the second protective section 2. The Y-shaped swing frame 32 provides multi-point support, allowing for a smooth transition between the first protective section 1 and the second protective section 2.

[0048] The flexible components of the universal joint device 3 enable the construction guardrail to quickly adapt to sandy or undulating terrain, avoiding the problems of suspension or tilting that occur with traditional guardrails. On-site construction only requires the installation of the first protective section 1, and the second protective section 2 can be installed by adjusting the angle through the universal joint device 3. There is no need to measure the ground or make repeated adjustments, which greatly simplifies the installation process.

[0049] See Figure 2 Multiple universal joint devices 3 are provided, and the multiple universal joint devices 3 are arranged at intervals along the direction of gravity. The multiple universal joints can enhance the stability of the connection between the first protective section 1 and the second protective section 2, and facilitate the second protective section 2 to determine the angle of conforming to the ground contour according to the position of the first protective section 1. At the same time, the multiple universal joint devices 3 can disperse the impact force when the building guardrail is subjected to external impact, avoid stress concentration on a single connection point, enhance the firmness of the connection, and improve the overall stability and impact resistance of the building guardrail.

[0050] See Figure 2 The first protective section 1 has a first connecting groove 11. One end of the Y-shaped swing frame 32 that connects to the first protective section 1 is located in the first connecting groove 11. The first connecting groove 11 is a groove structure of a specific shape, and its size and shape match the end of the Y-shaped swing frame 32. The main function of the first connecting groove 11 is to provide positioning and fixing space for the connection between the Y-shaped swing frame 32 and the first protective section 1. Embedding the end of the Y-shaped swing frame 32 into the connecting groove can ensure the accuracy and stability of the connection and prevent the Y-shaped swing frame 32 from shifting or falling out during use. Furthermore, it shortens the connection distance between the first protective section 1 and the second protective section 2 and prevents the gap between the first protective section 1 and the second protective section 2 from being too large, which would affect the safety of the construction site.

[0051] The second protective section 2 has a second connecting groove 21, and one end of the Y-shaped swing frame 32 that connects to the second protective section 2 is located in the second connecting groove 21. The first connecting groove 11 and the second connecting groove 21 can conceal most of the Y-shaped swing frame 32 within the protective section, thereby reducing the maintenance cost of the Y-shaped swing frame 32.

[0052] See Figure 2 One end of one of the Y-shaped swing brackets 32 is detachably connected to the first protective section 1;

[0053] One end of another Y-shaped swing bracket 32 ​​is detachably connected to the second protective section 2.

[0054] Indicatively, the Y-shaped swing frame 32 and the protective section can be connected by threads, bolts, or pins. During transportation, the construction safety railing can be disassembled into multiple parts, reducing transportation volume and ease of handling, thus improving transportation convenience. When the universal joint device 3 is damaged, it is not necessary to replace or remove the entire construction safety railing; only the universal joint device 3 needs to be replaced, reducing maintenance costs and extending the overall service life of the construction safety railing.

[0055] See Figure 1 and Figure 2 The first protective section 1 has multiple insertable blocks 4 on the side away from the second protective section 2; the second protective section 2 has multiple connector blocks 5 on the side away from the first protective section 1. The insertable blocks 4 of one construction project's protective railing are used to connect to the connector blocks 5 of another construction project's protective railing; the connector blocks 5 of another construction project's protective railing are used to connect to the insertable blocks 4 of another construction project's protective railing. This achieves modular connection between construction project protective railings. Through the cooperation of the insertable blocks 4 and connector blocks 5, adjacent construction project protective railings are securely connected, quickly constructing a continuous protective barrier and ensuring the safety of the construction site.

[0056] In one embodiment, one of the insertion block 4 and the connection block 5 is provided with a magnet, and the other is provided with a magnetic attraction element; schematically, the magnetic attraction element can be a magnet, or a component made of iron plate or ferromagnetic material. The magnet of one construction safety railing is used to attract the magnetic attraction element of another construction safety railing; the magnetic attraction element of one construction safety railing is used to attract the magnet of another construction safety railing. When the insertion blocks 4 and connection blocks 5 of the two construction safety railings approach each other, the attraction between the magnet and the magnetic attraction element will cause them to automatically align and fit tightly, reducing manual calibration during the connection process and improving the accuracy and speed of installation. Furthermore, the magnetic force between the magnet and the magnetic attraction element, to a certain extent, prevents the connecting parts from loosening due to vibration or external force, ensuring the stability of the construction safety railing during use.

[0057] See Figure 1 , Figure 2 and Figure 5 The bottom surface of the first protective section 1 is provided with at least two first insert rods 12; the bottom surface of the second protective section 2 is provided with at least two second insert rods 22. The first insert rods 12 and the second insert rods 22 can be inserted into the ground. The first insert rods 12 can fix the first protective section 1 in the vertical direction, and the second insert rods 22 can fix the second protective section 2, thereby fixing the entire construction project safety railing to the ground. When the construction project safety railing is subjected to lateral impact force, the first insert rods 12 and the second insert rods 22 can respectively resist the lateral displacement tendency of the first protective section 1 and the second protective section 2, maintaining the upright state of the construction project safety railing. Especially in construction sites with uneven terrain or strong winds, the stabilizing effect of the first insert rods 12 and the second insert rods 22 ensures that the construction project safety railing can stably perform its protective function and protect the safety of construction personnel and equipment.

[0058] See Figure 2 and Figure 5 The bottom of the first insertion rod 12 is a pointed structure 6; the bottom of the second insertion rod 22 is a pointed structure 6. The pointed structure 6 helps the first insertion rod 12 and the second insertion rod 22 to be inserted into the ground more easily. When the construction project guardrail is installed on the ground, by applying a certain pressure, the pointed structure 6 of the first insertion rod 12 or the second insertion rod 22 can pierce the ground surface and penetrate deep into the ground, thereby providing additional fixing force.

[0059] See Figure 2 and Figure 5The first protective section 1 has a first cavity 13, and the first cavity 13 contains a plurality of first springs 14. The first cavity 13 in the first protective section 1 provides a space for the plurality of first springs 14. The two ends of the first springs 14 are respectively connected to the horizontal opposite sides of the first protective section 1. The axial direction of the first springs 14 is parallel to the wall thickness direction of the building protective railing. The second protective section 2 has a second cavity 23, and the second cavity 23 contains a plurality of second springs 24. The two ends of the second springs 24 are respectively connected to the horizontal opposite sides of the second protective section 2. The axial direction of the second springs 24 is parallel to the wall thickness direction of the building protective railing. Construction safety railings can be constructed using thin stainless steel plates. When an external force impacts the railing, the impact deforms the plate, compressing the spring. The spring then undergoes corresponding elastic deformation based on the magnitude of the impact force, converting the impact energy into stored elastic potential energy. This reduces the direct impact of external forces on the railing, minimizing the risk of injury. The presence of the spring significantly enhances the protective performance and durability of the railing. By absorbing and dispersing impact energy, the spring reduces the likelihood of fatigue damage caused by frequent impacts, extending the service life of the railing.

[0060] See Figure 1 and Figure 2 The insert block 4 has a U-shaped structure, and the slot of the insert block 4 faces the height direction; the connecting block 5 has a U-shaped part 51; the U-shaped structure of the building guardrail is used to connect the U-shaped part 51 of another building guardrail; the U-shaped part 51 of the building guardrail is used to connect the U-shaped structure of another building guardrail. This structural design makes the connection between building guardrails more stable and convenient. When connecting two building guardrails, the U-shaped structure of one building guardrail can be inserted into the U-shaped part 51 of another building guardrail to form a nested connection. The shapes and sizes of the insert block 4 and the connecting block 5 match each other to ensure a tight connection that is not easy to loosen. Furthermore, it can realize the rapid insertion to build a continuous building guardrail barrier, improving the laying efficiency of building guardrails.

[0061] In the application of this application, the construction safety railing is used in an illustrative manner. The first protective section 1 of the first construction safety railing is first inserted into the ground according to the terrain. Then, the universal joint device 3 is used to adjust the second protective section 2 to conform to the terrain. The insertion block 4 of the first protective section 1 of the second construction safety railing is connected to the insertion block 5 of the second protective section 2 of the first construction safety railing, and magnetic assisted fixation is completed at the same time. The first protective section 1 of the second construction safety railing automatically aligns with the angle of the second protective section 2 of the first construction safety railing, and is quickly laid. Then, the angle of the second protective section 2 of the second construction safety railing is adjusted according to the universal joint device 3 of the second construction safety railing, and the railings are connected and installed in sequence.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
