[0029] like Figures 1 to 9 The diagram illustrates an embodiment of the external wall hole sealing device of this utility model. It includes a sealing component and a sealing rod 1. The sealing component comprises multiple sets of sealing plate assemblies 2, each 2 being rotatably connected to the sealing rod 1 for folding or unfolding. When the sealing component is folded, it reduces space occupation, allowing for quick passage through external wall holes. This not only facilitates operation but also improves the device's applicability to holes of different sizes. When unfolded, the sealing component fits snugly against the external wall to seal the hole. This external wall hole sealing device, through its folding and unfolding configuration, allows construction workers to install it from inside the external wall for sealing from the outside. Only one person is needed to complete the sealing operation, reducing high-altitude work and suspended platform installation time. This improves construction efficiency, reduces labor costs, ensures sealing quality, and enhances safety.

[0030] In this embodiment, each sealing plate assembly can also be folded or unfolded. Each group of sealing plate assemblies 2 includes a first sealing plate 21 rotatably connected to the sealing rod 1 and two second sealing plates 22 symmetrically arranged on both sides of the first sealing plate 21. The two second sealing plates 22 in each group are rotatably connected to the first sealing plate 21 in the same group. In this embodiment, not only can each sealing plate assembly 2 rotate relative to the sealing rod 1 to fold or unfold, but each sealing plate assembly 2 itself can also be folded or unfolded, better realizing unfolding sealing or folding to suit the construction of holes of different sizes.

[0031] In this embodiment, when the sealing component is fully unfolded, the sealing component can form a plane perpendicular to the sealing rod 1. When the sealing component is folded, each second sealing plate 22 rotates away from the sealing rod 1, and the two second sealing plates 22 in the same group move closer to each other; each first sealing plate 21 rotates towards the sealing rod 1.

[0032] In this embodiment, the sealing component also includes a center plate 3 connected to the sealing rod 1, and each sealing plate assembly 2 is rotatably connected to the center plate 3. The center plate 3 is provided with a mounting nut, and the sealing rod 1 has threads on its surface and is detachably connected to the center plate 3 via the mounting nut. Each first sealing plate 21 is rotatably connected to the center plate 3, and multiple first sealing plates 21 are evenly distributed along the outer periphery of the center plate 3. In this embodiment, the center plate 3 is square, and the number of sealing plate assemblies 2 is four. The four sealing plate assemblies 2 are tightly connected to the center plate 3: the four first sealing plates 21 correspond to and are tightly connected to the four sides of the center plate 3; the second sealing plate 22 is triangular, and in this embodiment, it is an equilateral right triangle, with its hypotenuse used for rotatable connection to the first sealing plates 21 in the same group. The four sealing plate assemblies 2 are connected to the center plate 3 to form a square planar structure perpendicular to the sealing rod 1 when unfolded, thereby increasing the sealing area and improving the sealing quality. When the sealing components are folded, the first sealing plate 21 rotates and folds toward the direction of the sealing rod 1, and the right-angle vertices 221 of the two second sealing plates 22 in the same group move away from the sealing rod 1 and move closer to each other.

[0033] In this embodiment, an adjustment component is also included. The adjustment component includes a push-pull member 4 and multiple connecting members 5. Each sealing plate assembly 2 is connected to the push-pull member 4 via a connecting member 5. The push-pull member 4 is slidably connected to the sealing rod 1 to control the movement of the sealing plate assembly 2, thereby realizing the folding or unfolding function of the sealing component. In this embodiment, the push-pull member 4 includes a sleeve that is slidably fitted outside the sealing rod 1. One end of each connecting member 5 is connected to the sleeve, and the other end is connected to the corresponding first sealing plate 21 and / or second sealing plate 22.

[0034] In this embodiment, each connector 5 is detachably connected to the sealing plate assembly 2. The detachable connection method can be flexibly selected based on the technical knowledge of those skilled in the art. For example, the adjustment component also includes a connecting ring provided on the corresponding first sealing plate 21 or second sealing plate 22. Each connector 5 has a locking hook at the end away from the push-pull member 4 to be detachably connected to the connecting ring. When the sealing plate assembly 2 is unfolded and attached to the outside of the wall, multiple locking hooks can be separated from the corresponding connecting rings to disassemble the push-pull member 4 and multiple connectors 5. At this time, only the sealing rod 1 is placed in the hole. When the concrete poured into the hole later reaches a certain strength, the sealing rod 1 can be disassembled, and the external wall hole sealing device can be completely disassembled. There is no residue in the concrete, which not only ensures construction cost but also improves sealing quality and ensures sealing tightness. When the hole is small, the connector 5 can also be connected to the corresponding first sealing plate 21 and / or second sealing plate 2 by wire. During construction, quick disassembly is achieved by inserting the disassembly device into the hole and cutting the wire.

[0035] In this embodiment, a fixing component is also included, which includes a clamping plate 6. The clamping plate 6 is slidably connected to the sealing rod 1 to adjust the distance between it and the sealing plate assembly 2.

[0036] The fixing component also includes a fastening nut 7. The surface of the sealing rod 1 is threaded, and the clamping plate 6 has a movable hole to be fitted onto the sealing rod 1 and limited by the fastening nut 7, which can be threadedly connected to the sealing rod 1. In this embodiment, the sealing component is placed outside the exterior wall, the clamping plate 6 is placed inside the exterior wall, and the movement of the clamping plate 6 is limited by the fastening nut 7 to clamp and fix the exterior wall hole sealing device to the wall. When the sealing component is fixed outside the exterior wall to seal the hole, the clamping plate 6, which is located inside the exterior wall, can not only play a fixing role, but also partially seal the hole. For example, the bottom of the hole can be sealed by the clamping plate 6, and the gap between the clamping plate 6 and the top of the hole forms a mortar outlet 9 to facilitate filling the hole with sealing materials such as concrete. In other embodiments, the clamping plate 6 can also cover the entire hole, and the mortar outlet 9 can be formed by opening a pouring hole on the clamping plate 6 to realize the function of filling sealing materials.

[0037] The method of using this utility model includes the following steps:

[0038] Construction workers fold the sealing component on one side of the exterior wall. Using the sealing rod 1, they move the folded sealing component in the first direction to pass it through the hole. They then move the push-pull component 4 in the second direction and, through multiple connectors 5, move the sealing plate assembly 2 to unfold the sealing component. The unfolded sealing component fits against the exterior wall to seal the hole on the other side of the exterior wall.

[0039] In this embodiment, the first direction is opposite to the second direction.

[0040] The specific working process of this embodiment is as follows:

[0041] The sealing rod 1, sealing component, push-pull component 4, and multiple connectors 5 are interconnected. Construction workers stand inside the exterior wall and fold the sealing component to reduce space occupation. Specifically, the folding method involves rotating the two second sealing plates 22 of each group away from the sealing rod 1 and rotating each first sealing plate 21 towards the sealing rod 1. In a specific application scenario, when the construction worker is inside the wall and the sealing component is fully unfolded, the sealing component is parallel to the wall with its back facing the wall and its front facing away from the wall. The sealing rod 1 is perpendicular to the wall. Folding the sealing component involves first folding each second sealing plate 22 towards the wall so that its right-angle vertex 221 points towards the wall, and then rotating each first plate 21 towards the rod 1 to complete the folding. At this point, the intersection of each connector 5 and the push-pull component 4 is closer to the wall than its intersection with the corresponding first sealing plate 21 or second plate 22.

[0042] The folded sealing component is passed through the hole via the sealing rod 1. Then, the push-pull piece 4, which is slidably mounted on the sealing rod 1, is pulled back, and the first sealing plate 21 and the second sealing plate 22 are moved through multiple connecting pieces 5, causing the sealing component to unfold and seal the hole on the outside of the exterior wall. It should be understood that the above description of the usage scenario is only for the convenience of describing the folding and unfolding method of this embodiment, and does not specify the folding order of the first sealing plate 21 and the second sealing plate 22. Their relative relationship with the wall surface when unfolded or folded can be adjusted based on the usage location of the exterior wall hole sealing device and the adaptability of the scenario.

[0043] Separate the multiple connectors 5 from the corresponding first sealing plate 21 and / or second sealing plate 22 to disassemble the push-pull member 4 and the multiple connectors 5.

[0044] Inside the exterior wall, the clamping plate 6 is fitted onto the sealing rod 1, and the clamping plate 6 and the sealing component are clamped to both sides of the exterior wall by tightening the nuts 7. Concrete is then injected into the ash outlet 9 to fill the internal space of the hole.

[0045] Once the concrete reaches a certain strength, the external wall hole sealing device can be completely disassembled for reuse.

[0046] This embodiment can reduce the hidden dangers of high-altitude operations outside the wall, reduce the need for suspended platform installation, ensure the sealing quality, allow one person to carry out the work independently, and the device can be disassembled and reused, thereby improving sealing efficiency, ensuring sealing quality, and reducing construction costs.

[0047] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
