Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a quick-sealing device for screw holes in the wall support of a climbing scaffold with reinforced rock wool strip composite panels. Background Technology

[0002] As a commonly used construction scaffolding device in high-rise buildings, the post-construction repair of its wall-mounted supports is receiving increasing attention from engineers. Traditional methods for sealing the bolt holes of these supports require plugging with dry-hardened cement mortar from the outside, followed by injecting mortar from the inside after the outer mortar has fully set. This method is sufficient for buildings without reinforced rock wool composite panels, provided the construction quality is maintained. However, for walls using reinforced rock wool composite panels, higher construction efficiency is required. Once the scaffolding supports are removed, the holes must be immediately plugged and sealed. Otherwise, with only two layers of supports remaining after removal, the scaffolding will remain stationary for an extended period, affecting its stability and safety. Traditional methods of plugging bolt holes require the dry-hardened mortar to fully set to achieve sufficient strength, and rapid plugging cannot guarantee a tight seal, leading to the risk of leakage in the exterior wall. Therefore, a rapid plugging device for the bolt holes of reinforced rock wool composite panel climbing scaffolding wall-mounted supports is needed to address these issues. Utility Model Content

[0003] The technical problem to be solved by this utility model is to address the shortcomings of the prior art by providing a quick-sealing device for screw holes in climbing frame wall supports of reinforced rock wool strip composite panels. Its structure is reasonably designed. By setting a fixing plate at the end of the concrete sealing component and setting a rubber waterproof pad on the fixing plate, the screw holes can be quickly sealed, thus not affecting the installation of the integrated insulation board of the exterior wall. It can effectively improve construction efficiency, improve waterproofing effect, and reduce the risk of leakage of the exterior wall.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a quick-sealing device for screw holes of reinforced rock wool strip composite board climbing frame wall support, including a concrete sealing component for inserting into one end of the screw hole and for quick sealing thereunder. One end of the concrete sealing component extending into the screw hole is provided with a pre-embedded steel bar, and the other end of the concrete sealing component is provided with a fixing plate. The fixing plate and the concrete sealing component are connected by a pre-embedded plate, one end of which is embedded in the concrete sealing component, and the other end of which is fixedly connected to the fixing plate. The fixing plate is connected to the outer wall around the screw hole by screws. A rubber waterproof pad is provided on the side of the fixing plate near the concrete sealing component. The cross-section of the concrete sealing component is circular, and the diameter of the end of the concrete sealing component extending into the screw hole is smaller than the diameter of the other end of the concrete sealing component.

[0005] The aforementioned quick-sealing device for screw holes in the reinforced rock wool strip composite board climbing frame wall support includes a fixing plate comprising a circular ring plate and two connecting plates symmetrically arranged on both sides of the circular ring plate.

[0006] The aforementioned quick-sealing device for screw holes in the reinforced rock wool strip composite board climbing frame wall support has pre-drilled holes on the connecting plate for screws to pass through.

[0007] In the aforementioned quick-sealing device for screw holes of the reinforced rock wool strip composite board climbing frame wall support, the rubber waterproof pad is annular, and the outer diameter of the rubber waterproof pad is larger than the diameter of the screw hole.

[0008] In the aforementioned quick-sealing device for screw holes of the reinforced rock wool strip composite board climbing frame wall support, the inner diameter of the annular plate is smaller than the hole diameter of the screw hole and not smaller than the inner diameter of the rubber waterproof pad, and the outer diameter of the annular plate is not smaller than the outer diameter of the rubber waterproof pad.

[0009] The aforementioned quick-sealing device for screw holes in the climbing frame wall support of reinforced rock wool strip composite board has a rectangular embedded plate with one end fixed to the inner ring of a circular plate. The end of the embedded plate extending outside the concrete sealing component is flush with the outer side of the circular plate.

[0010] The aforementioned quick-sealing device for screw holes in the reinforced rock wool strip composite board climbing frame wall support includes a concrete sealing component comprising a first cylindrical section, a tapered variable diameter section, a second cylindrical section, and an enlarged end arranged sequentially from the end furthest from the fixed plate to the end closest to the fixed plate. The diameter of the first cylindrical section is equal to the minimum diameter of the tapered variable diameter section, the diameter of the second cylindrical section is equal to the maximum diameter of the tapered variable diameter section, and the maximum diameter of the enlarged end is equal to the diameter of the screw hole.

[0011] The aforementioned quick-sealing device for screw holes in the climbing frame wall support of reinforced rock wool strip composite board is provided, wherein the pre-embedded steel bars and concrete sealing components are arranged coaxially.

[0012] This utility model has the following advantages compared with the prior art: 1. This utility model sets a fixing plate at the end of the concrete sealing component and connects the fixing plate to the external wall with screws. When the climbing frame support is removed, the screw hole can be quickly sealed, thus not affecting the installation of the integrated external wall insulation board, which can effectively improve construction efficiency.

[0013] 2. This utility model improves the waterproof effect and reduces the risk of leakage by setting a rubber waterproof pad on the fixing plate to seal the gap between the fixing plate and the exterior wall.

[0014] 3. This utility model provides a pre-embedded steel bar at one end of the concrete sealing component that extends into the screw hole. This pre-embedded steel bar can solve the problem of bonding between the concrete sealing component and the subsequent grouting mortar in the screw hole, ensuring a stronger overall bond between the new and old materials.

[0015] In summary, the present invention has a reasonable structural design. By setting a fixing plate at the end of the concrete sealing component and setting a rubber waterproof pad on the fixing plate, the screw hole can be quickly sealed, thus not affecting the installation of the integrated external wall insulation board. This can effectively improve construction efficiency, enhance waterproofing, and reduce the risk of external wall leakage.

[0020] like Figure 1 and Figure 2 As shown, this utility model includes a concrete sealing component 2 for quickly sealing one end of a screw hole 1. One end of the concrete sealing component 2 extending into the screw hole 1 is provided with a pre-embedded reinforcing bar 3, and the other end of the concrete sealing component 2 is provided with a fixing plate 4. The fixing plate 4 and the concrete sealing component 2 are connected by a pre-embedded plate 5. One end of the pre-embedded plate 5 is embedded in the concrete sealing component 2, and the other end of the pre-embedded plate 5 is fixedly connected to the fixing plate 4. The fixing plate 4 is connected to the outer wall surrounding the screw hole 1 by screws 6. A rubber waterproof pad 7 is provided on the side of the fixing plate 4 near the concrete sealing component 2. The cross-section of the concrete sealing component 2 is circular, and the diameter of the end of the concrete sealing component 2 extending into the screw hole 1 is smaller than the diameter of the other end of the concrete sealing component 2.

[0021] In actual use, by setting a fixing plate 4 at the end of the concrete sealing component 2 and connecting the fixing plate 4 to the outer wall with screws, the screw hole 1 can be quickly sealed after the climbing frame support is removed, thus not affecting the installation of the integrated insulation board of the outer wall and effectively improving construction efficiency.

[0022] It should be noted that the rubber waterproof gasket 7 is glued to one side of the fixing plate 4. By setting the rubber waterproof gasket 7 on the fixing plate 4, the gap between the fixing plate 4 and the external wall can be sealed by the rubber waterproof gasket 7, thereby improving its waterproof effect and reducing the risk of leakage from the external wall.

[0023] In addition, by setting a pre-embedded steel bar 3 at one end of the concrete sealing part 2 that extends into the screw hole 1, the pre-embedded steel bar 3 can solve the problem of bonding between the concrete sealing part 2 and the post-grouting mortar in the screw hole 1, and ensure the overall integrity of the bonding between the new and old materials is strengthened.

[0024] In this embodiment, the fixing plate 4 includes an annular plate 41 and two connecting plates 42 symmetrically arranged on both sides of the annular plate 41.

[0025] In actual use, the fixing plate 4 and the connecting plate 42 are integrally formed, and the fixing plate 4 is a steel plate.

[0026] In this embodiment, the connecting plate 42 has a through hole 8 for the screw 6 to pass through.

[0027] In this embodiment, the rubber waterproof pad 7 is annular, and the outer diameter of the rubber waterproof pad 7 is larger than the diameter of the screw hole 1.

[0028] In this embodiment, the inner diameter of the annular plate 41 is smaller than the diameter of the screw hole 1 and not smaller than the inner diameter of the rubber waterproof pad 7, and the outer diameter of the annular plate 41 is not smaller than the outer diameter of the rubber waterproof pad 7.

[0029] In this embodiment, the embedded plate 5 is rectangular and one end of it is fixed to the inner ring of the annular plate 41. The end of the embedded plate 5 extending outside the concrete sealing component 2 is flush with the outer side of the annular plate 41.

[0030] In this embodiment, the concrete sealing component 2 includes a first cylindrical section 21, a tapered variable diameter section 22, a second cylindrical section 23, and an enlarged end 24 arranged sequentially from the end away from the fixed plate 4 to the end closer to the fixed plate 4. The diameter of the first cylindrical section 21 is equal to the minimum diameter of the tapered variable diameter section 22, the diameter of the second cylindrical section 23 is equal to the maximum diameter of the tapered variable diameter section 22, and the maximum diameter of the enlarged end 24 is equal to the diameter of the screw hole 1.

[0031] In practice, the diameter of the second cylindrical section 23 is smaller than the diameter of the screw hole 1, and the enlarged end 24 is used to expand one end of the second cylindrical section 23 outward until it fits against the hole wall of the screw hole 1.

[0032] In practical use, the concrete sealing component 2 adopts an alternating design of conical and cylindrical sections to form a multi-level sealing surface. By fitting the conical surfaces together, the contact area with the wall of the screw hole 1 is increased, reducing the risk of local stress concentration. Moreover, this structure is similar to the "conical surface fitting" principle of the inverted conical anchor bolt, which can improve the pull-out resistance by about 50%. In addition, the segmented structure allows each segment to adjust the cone angle independently (such as 60°-90°). By optimizing the cone angle through fluid simulation, a more uniform mortar flow and pressure distribution can be achieved.

[0033] It should be noted that the cylindrical section in the concrete sealing component 2 can be used as a positioning reference to simplify the centering operation during installation and avoid the deviation problem caused by the direct insertion of the conical section. In addition, the segmented design of the concrete sealing component 2 facilitates the staged grouting. The consistency of the grout and the grouting pressure of each segment can be controlled in a targeted manner to reduce voids or delamination defects. For example, the conical section can use high water retention mortar with a delamination degree of ≤30mm, while the cylindrical section focuses on fluidity.

[0034] In this embodiment, the pre-embedded steel bar 3 and the concrete sealing component 2 are arranged coaxially.

[0035] In actual use, the climbing frame support is first removed, and then the sealing device is inserted into the screw hole 1, so that the rubber waterproof pad 7 on the inner side of the fixing plate 4 is in contact with the surface of the outer wall. The fixing plate 4 is then fastened to the outer wall by screws 6, and the rubber waterproof pad 7 is squeezed. After the outer side construction is completed, indoor grouting can be carried out by injecting cement mortar into the screw hole 1.

[0036] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
