Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a sealing device for adjacent walls and ordinary reserved openings. Background Technology

[0002] During the construction of building projects, when the shorter side of a vertical opening is less than 500mm, sealing measures should be taken to prevent people from falling and eliminate safety hazards.

[0003] Traditional methods of sealing openings typically involve using timber and formwork, directly nailed to the floor slab, or custom-made protective panels for the opening dimensions. For openings adjacent to walls, nailing not only damages the structural structure but also results in insecure fixation and easy loosening. Custom-made protective panels cannot be applied to openings of different sizes, are inconvenient to disassemble and reuse, and are difficult to handle, reducing work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a sealing device for wall-mounted and ordinary reserved openings. Through the combined action of the adjustment mechanism and the limiting mechanism, the specifications of the sealing device can be adjusted at will according to the size of the opening, so as to achieve sealing of any wall-mounted and ordinary reserved openings. The whole process is simple to operate, highly versatile, and has a high turnover rate, thus achieving the purpose of reducing costs, increasing efficiency, and improving project quality.

[0005] This utility model is achieved through the following technical solution:

[0006] A sealing device for use in wall-mounted and conventional pre-reserved openings, comprising:

[0007] A protective panel, wherein multiple protective panels are arranged together to form a frame structure, and the frame structure is supported on the outer edge of the reserved opening;

[0008] An adjustment mechanism is located inside the frame structure, and both ends of the adjustment mechanism are respectively connected to the inner sidewall of the frame structure via sliding components, which allow the adjustment mechanism to slide along the inner edge of the frame structure.

[0009] A limiting mechanism, comprising a first limiting component and a second limiting component, wherein the first limiting component is fixedly connected to the corner of the frame structure, and the second limiting component is connected below the adjusting mechanism and slides with the adjusting mechanism;

[0010] A cover plate that covers the upper surface of the frame structure.

[0011] In this design, the frame structure formed by the interconnected protective plates provides basic support for the entire device and fits tightly with the outer edge of the reserved opening, playing a preliminary protective and positioning role. The adjustment mechanism is connected to the frame structure through a sliding component, allowing it to slide flexibly within the frame. This enables the device to be adaptively adjusted according to different opening sizes, enhancing its versatility. Meanwhile, the first limiting component of the limiting mechanism is fixed at the corner of the frame, and the second limiting component slides with the adjustment mechanism. Both limit the device from multiple dimensions, ensuring its stability and safety at the opening. When the cover plate covers the upper surface of the frame, it can further prevent personnel or objects from falling through the opening, ensuring the safety of the construction site.

[0012] As a further embodiment of the sealing device, the cover plate is connected to one side of the frame structure via a hinge mechanism.

[0013] In this design, the cover plate is connected to one side of the frame structure via a hinge mechanism, giving it an openable and closable function. When it is necessary to inspect, maintain, or perform related construction operations above the opening, the cover plate can be easily opened, allowing workers to access the opening and improving operational convenience. When the opening is not in use, the cover plate can be quickly closed, restoring the opening to its protective state and ensuring the safety of personnel and materials at the construction site.

[0014] As a further embodiment of the sealing device, the free end of the cover plate and the side end of the frame structure are provided with matching latches.

[0015] In this design, the locking mechanism securely fastens the cover plate to the frame structure, preventing unauthorized personnel from opening the cover plate and effectively reducing the risk of accidents, thus ensuring the safety of personnel at the construction site. Simultaneously, the locking mechanism ensures that the cover plate will not easily open even when the device is subjected to external impacts, such as collisions with objects or accidental contact by personnel, keeping the sealing device in a state of optimal protection at all times.

[0016] As a further embodiment of the sealing device, the first limiting component includes a first limiting plate, which is an angle steel cut from a stainless steel plate and welded to the upper end face of one corner of the frame structure. When the reserved opening is adjacent to a wall, the first limiting plate is placed close to the wall edge.

[0017] In this solution, the first limiting plate is made of stainless steel angle steel and welded to the upper end of one corner of the frame. When facing the reserved opening in the wall, it is placed close to the wall side, which can effectively prevent the sealing device from being displaced or overturned to the wall side due to external forces, such as people stepping on it or objects hitting it.

[0018] As a further embodiment of the sealing device, the first limiting component also includes a second limiting plate, which is an angle steel cut from a stainless steel plate and welded to the lower end face of the same corner as the first limiting plate, and the second limiting plate is at least a resting distance away from the outer edge of the corner.

[0019] In this design, the second limiting plate and the first limiting plate together enhance the limiting effect of the sealing device. When the device is placed at the opening, the second limiting plate can interact with the edge of the opening to limit the horizontal displacement of the device and prevent the sealing device from sliding along the edge of the opening.

[0020] As a further embodiment of the blocking device, the adjusting mechanism includes a pair of position adjusting plates, which are orthogonally distributed and can slide relative to each other.

[0021] In this design, orthogonally distributed, mutually sliding pairs of position adjustment plates allow the sealing device to precisely adapt to various sizes and shapes of adjacent walls and ordinary pre-reserved openings. In actual construction scenarios, workers can flexibly adjust the internal dimensions of the sealing device by sliding the position adjustment plates according to the specific size of the opening, ensuring a tight fit and efficient sealing. This not only improves the device's versatility and reduces the hassle of frequently replacing sealing devices of different specifications due to differences in opening dimensions, but also increases work efficiency, reduces construction costs, and makes sealing operations more convenient and efficient.

[0022] As a further embodiment of the sealing device, the sliding assembly includes a support plate, and the inner walls of all the protective plates are connected to the support plate. The upper surface of the support plate is provided with a first guide groove, and the two ends of the position adjusting plate slide along the oppositely arranged first guide grooves through limiting nuts.

[0023] In this design, the support plate is connected to the inner wall of the protective plate, providing a stable support foundation for the position adjustment plate and ensuring the stability of the entire adjustment structure. The first guide groove is formed on the upper surface of the support plate, defining the direction of the sliding of the position adjustment plate, ensuring that the position adjustment plate can only move along a specific path, thus ensuring that the adjustment process is precise and orderly. The limiting nut connects the position adjustment plate to the first guide groove, not only realizing the sliding function of the position adjustment plate, but also allowing for flexible control of the fixed state of the position adjustment plate by tightening or loosening the limiting nut.

[0024] As a further embodiment of the sealing device, the position adjustment plate has a second guide groove in the middle along its own length direction, and the second guide grooves on the position adjustment plate, which are arranged in pairs, are locked at the intersection by corresponding limit nuts.

[0025] In this design, the second guide groove, in conjunction with the limiting nut, allows for more precise and flexible size adjustment of the paired position adjustment plates as they slide relative to each other. Construction personnel can freely adjust the relative positions of the position adjustment plates within a wider range based on the actual size of the opening, greatly enhancing the device's adaptability to openings of different sizes and ensuring a tight fit to various openings, thus improving the sealing effect.

[0026] As a further embodiment of the sealing device, the second limiting component includes a third limiting plate, which is an angle steel cut from a stainless steel plate. The third limiting plate is welded to the lower end of the limiting nut at the intersection of the paired position adjusting plates and moves synchronously with the position adjusting plates.

[0027] In this design, when the position adjustment plate is adjusted according to the size of the opening, the third limiting plate will also move to the corresponding position. It provides additional horizontal restraint to the sealing device, enhancing its resistance to horizontal forces and preventing horizontal displacement of the sealing device at the opening. Especially when the opening shape is irregular or affected by lateral forces, the third limiting plate effectively maintains the stability of the device, ensuring that it always maintains a good sealing state at the opening.

[0028] As a further embodiment of the sealing device, the second limiting component also includes a fourth limiting plate, which is connected to the free end of the third limiting plate, and the fourth limiting plate and the third limiting plate form a hook for engaging with the reserved opening near the floor slab.

[0029] In this design, when the sealing device is placed at the pre-reserved opening, the hook can be firmly engaged with the floor slab near the opening, providing strong support and restraint from below. This not only effectively prevents the sealing device from swaying or shifting during use, ensuring it securely covers the opening and reducing the risk of people and objects falling through, but also provides additional anchoring force in case of accidents such as accidental stepping or equipment collision, making the device less likely to be overturned or displaced.

[0030] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0031] 1. This utility model, by setting an adjustable position adjustment plate and cooperating with the limit nut, can flexibly adjust the size of the sealing device according to the actual size of the opening; whether it is a wall-mounted opening or an ordinary reserved opening, it can easily achieve sealing, which greatly improves the versatility of the device. After use, the device can be easily removed by adjusting the limit nut, which is convenient for recycling and reuse, improving work efficiency and reducing construction costs.

[0032] 2. This utility model achieves drilling-free installation through the first limiting component and the second limiting component, reducing damage to the main structure; the first limiting component ensures that the device will not fall off when stepped on when used at wall openings; the second limiting component limits the device from multiple directions, so that the sealing device can be stably fixed in the left, right, up and down directions, effectively reducing the complexity of edge protection construction and improving the convenience and safety of construction.

[0033] 3. This utility model has a locking buckle welded on the cover plate, which locks the cover plate to the protective plate to prevent it from being opened or damaged by others, thus ensuring the safety and civilized construction quality of the construction site. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0041] Example 1

[0042] This embodiment 1 provides a sealing device for adjacent walls and ordinary reserved openings, such as... Figures 1-3As shown, the device includes protective plates 2, an adjustment mechanism, a limiting mechanism, and a cover plate 1. Four protective plates 2, cut from stainless steel, are joined together to form a rectangular frame structure, providing basic support for the entire device. The frame structure supports the outer edge of the reserved opening and fits tightly with it, providing initial protection and positioning. The adjustment mechanism is located inside the frame structure, with both ends connected to the inner wall of the frame structure via sliding components. These components allow the adjustment mechanism to slide along the inner edge of the frame structure, enabling adaptive adjustments based on different opening sizes and enhancing versatility. The limiting mechanism includes a first limiting component and a second limiting component. The first limiting component is fixedly connected to the corner of the frame structure, while the second limiting component is connected below the adjustment mechanism and slides with it, limiting the device from multiple dimensions to ensure its stability and safety at the opening. The cover plate 1 covers the upper surface of the frame structure to prevent personnel or objects from falling through the opening, ensuring safety at the construction site.

[0043] Please refer to Figure 1 As shown, the cover plate 1 is cut from a single piece of stainless steel. The outer edge of the cover plate 1 is the same size as the frame structure. A hinge 4 is installed at one edge of the cover plate 1 and connected to the protective plate 2, giving the cover plate 1 the function of opening and closing. The free end of the cover plate 1 and the side end of the frame structure are equipped with matching latches 5 for locking, preventing unauthorized personnel from opening the cover plate 1, and effectively reducing the risk of accidents.

[0044] Please refer to Figure 1 As shown, the adjustment mechanism includes a pair of position adjustment plates 3, and the sliding component includes a support plate. The inner walls of all protective plates 2 are connected to the support plate. The pair of position adjustment plates 3 are orthogonally distributed and connected to the corresponding support plates. The pair of position adjustment plates 3 can slide relative to each other, so that the sealing device can accurately adapt to various sizes and shapes of adjacent walls and ordinary reserved openings. Specifically, the upper surface of the support plate is provided with a first guide groove. The two ends of the position adjustment plate slide along the oppositely arranged first guide groove through the limit nut 6. In application, the range of movement of the position adjustment plate 3 can be controlled by controlling the length of the guide groove. For example, according to the specification requirements, vertical openings and non-vertical openings with a short side length of less than 500mm need to be sealed. That is, when the limit nut 6 slides along the guide groove to the edge limit position, the position and length of the guide groove meet the maximum size of the opening to be sealed according to the specification requirements.

[0045] Meanwhile, in this embodiment, the position adjustment plate 3 is made of two strip steel plates cut from stainless steel plate, that is, the pair of position adjustment plates 3 are staggered with each other, and a second guide groove is cut in the middle part of the position adjustment plate 3 according to the size of the limiting nut 6. The second guide groove is cut along the length direction of the position adjustment plate 3. The second guide grooves on the pair of position adjustment plates 3 are locked at the intersection by the corresponding limiting nut 6. Therefore, the position of the position adjustment plate 3 on the support plate can be adjusted at will according to the size of the opening, thereby achieving the protection requirements.

[0046] Please refer to the following: Figure 1 and Figure 2 As shown, the first limiting component includes a first limiting plate 7. The first limiting plate 7 is an angle steel cut from a stainless steel plate and welded to the upper end face of one corner of the frame structure. When the reserved opening is adjacent to a wall, the first limiting plate 7 is placed close to the wall side. In this way, the first limiting plate 7 can effectively prevent the sealing device from shifting or flipping to the side adjacent to the wall due to external forces, such as people stepping on it or objects hitting it.

[0047] Meanwhile, the first limiting component also includes a second limiting plate 8. The second limiting plate 8 is an angle steel cut from a stainless steel plate and welded to the lower end face of the same corner as the first limiting plate 7. The second limiting plate 8 is at least a resting distance away from the outer edge of the corner. When the device is placed in the opening, the second limiting plate 8 can interact with the edge of the opening to limit the horizontal displacement of the device and prevent the sealing device from sliding along the edge of the opening.

[0048] To further limit the displacement of the limiting device, please refer to [link / reference needed]. Figure 1 and Figure 2 As shown, the second limiting component includes a third limiting plate 9, which is an angle steel cut from stainless steel plate. The third limiting plate 9 is welded to the lower end of the limiting nut 6 at the intersection of the paired position adjusting plates 3. It moves synchronously with the position adjusting plates 3. When the position adjusting plates 3 are adjusted according to the size of the opening, the third limiting plate 9 will also move to the corresponding position. The third limiting plate 9 plays an additional limiting role for the sealing device in the horizontal direction, enhancing the device's ability to resist horizontal external forces.

[0049] Meanwhile, the second limiting component also includes a fourth limiting plate 10, which is connected to the free end of the third limiting plate 9. The fourth limiting plate 10 and the third limiting plate 9 form a hook for engaging with the reserved opening near the floor slab. When the sealing device is placed in the reserved opening, this hook can be tightly engaged with the reserved opening near the floor slab, providing strong support and limiting the device from below, thus achieving the upper and lower limit requirements of the sealing device.

[0050] The implementation principle of this embodiment:

[0051] Installation at a standard pre-reserved opening: Move the sealing device to the standard pre-reserved opening. First, align one corner of the frame structure with one corner of the opening, so that the protective plate 2 is supported on the outer edge of the opening. Adjust the size using the adjustment mechanism. Loosen the limiting nut 6 and slide the position adjustment plate along the first guide groove according to the size of the opening. At the same time, use the second guide groove in the middle of the position adjustment plate 3 and the limiting nut 6 at their intersection to precisely adjust the internal size of the device until it fits the opening. After adjustment, tighten the limiting nut 6 to fix the position adjustment plate 3. Then, let the hook formed by the fourth limiting plate 10 and the third limiting plate 9 of the second limiting component engage with the floor slab near the opening to complete the upper and lower limits of the device. Finally, close the cover plate 1 and lock the cover plate 1 to the frame structure with the latch 5 to prevent accidental opening.

[0052] Installation at the pre-reserved opening in the wall: Move the sealing device to the pre-reserved opening in the wall, and place the corner of the protective plate with the first limiting plate 7 welded to it tightly against the wall edge, ensuring a tight fit between the first limiting plate 7 and the wall. Then, using its blocking device, flip it to one side of the wall. Next, as with ordinary pre-reserved opening installation, adjust the position adjusting plate 3 to fit the opening size and fix it in place. Ensure that the hook of the second limiting component is engaged near the floor slab at the opening, achieving upper and lower limiting. After completion, close the cover plate 1 and lock it with the latch 5 to ensure the safety of the opening.

[0053] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
