Technical Field

[0001] The utility model relates to the technical field of wall reserved hole blocking construction, in particular to a concrete outer wall screw hole blocking device. Background Art

[0002] At present, a large number of through-wall screws are used in the construction of the exterior walls of shear walls and frame-shear structures. The sealing of through-wall screw holes involves the risk of leakage in the exterior walls, and must be taken seriously during construction. In the case of exterior wall leakage, a large part is caused by the loose sealing of the screw holes. The traditional methods of sealing the screw holes in the exterior walls are: flushing out the PVC pipe and cleaning it; first filling the inner wall with cement sand; filling the expansion cement mortar from the outside to the inside, inserting steel bars, smoothing the surface, and then applying cement-based waterproof coating. This method is not easy to operate, the depth of cement mortar insertion cannot be controlled, and the sealing does not meet the requirements.

[0003] Therefore, it is necessary to provide a new concrete exterior wall screw hole plugging device to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] See also Figures 1 to 5 The embodiment of the utility model provides a concrete exterior wall screw hole sealing device, which includes: an abutment plate 1, a sealing component 3 and a driving component 4.

[0025] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A coaxially arranged threaded rod 2 is fixedly embedded on the abutment disk 1, and a blocking component 3 and a driving component 4 are sleeved on the threaded rod 2;

[0026] The sealing component 3 includes an elastic pleated airbag 31, which is sleeved on the threaded rod 2, and an annular center connecting plate 32 is fixedly embedded at the bottom of the elastic pleated airbag 31, and an elastic storage bag 33 is fixedly installed at the bottom of the annular center connecting plate 32, and the elastic storage bag 33 is filled with a foaming agent 332, and the annular center connecting plate 32 and the elastic storage bag 33 are coaxially arranged with the elastic pleated airbag 31, and the annular center connecting plate 32 and the elastic storage bag 33 are sleeved on the threaded rod 2, the bottom of the elastic storage bag 33 is fixedly connected to the inner disk wall of the abutting disk 1, and a thin bag groove 331 is opened on the outer circle bag wall of the elastic storage bag 33.

[0027] It should be noted that: the threaded rod 2 is used to insert the abutment disk 1 into the screw hole of the concrete outer wall, and the driving component 4 is used to press the elastic pleated airbag 31. As the elastic pleated airbag 31 is compressed and radially expanded and extended, the elastic storage bag 33 is also compressed and radially expanded and extended. Since a thin bag groove 331 is provided on the outer wall of the elastic storage bag 33, as the outer wall of the elastic storage bag 33 is restricted by the screw hole and the thin bag groove 331 is forced to withstand the pressure to the limit, the thin bag groove 331 cracks, so that the foaming agent 332 in the elastic storage bag 33 is sprayed out, so that the gap between the elastic pleated airbag 31 and the screw hole can be filled very quickly and cooperate with the expanded elastic pleated airbag 31 to avoid the elastic pleated airbag 31 from falling out or leaking. The expanded elastic pleated airbag 31 can completely block the screw hole, improve the sealing degree, and prevent leakage. Subsequently, cement can be used to smooth the screw hole of the concrete outer wall.

[0028] It is worth noting that after the elastic storage bag 33 is broken, the contact force of the inner bag wall of the elastic pleated airbag 31 is reduced. At this time, the driving component 4 is continued to compress the elastic pleated airbag 31 to further enhance the sealing and firmness of the elastic pleated airbag 31 and the screw hole;

[0029] Wherein, a plurality of ground spikes 11 are fixedly installed at the bottom of the abutment plate 1, so as to increase the friction force at the bottom of the screw hole of the concrete outer wall.

[0030] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The driving assembly 4 includes a threaded socket disk 41, which is sleeved on the threaded rod 2 and threadedly connected to the threaded rod 2, and a rotating ring 44 for driving the threaded socket disk 41 to rotate is installed on the threaded socket disk 41. Specifically, the bottom plate surface of the threaded socket disk 41 is fixedly connected to the upper bag wall of the elastic pleated airbag 31, and a plurality of annularly distributed sleeves 42 are fixedly installed on the threaded socket disk 41, and a sliding rod 43 with a sliding connection is inserted in each of the sleeves 42. The rotating ring 44 is fixedly mounted on the rod heads of the plurality of sliding rods 43, and the rotating ring 44 is sleeved on the annular groove 2a opened at the end of the threaded rod 2 and is rotatably connected to the annular groove 2a.

[0031] It should be noted that: by rotating the rotating ring 44, the sliding rod 43 drives the threaded socket disk 41 to be screwed in along the threaded rod 2 through the sleeve 42, so that when the threaded socket disk 41 is screwed in along the threaded rod 2, the sleeve 42 slides along the sliding rod 43 to extend, and as the threaded socket disk 41 is screwed in along the threaded rod 2, the threaded socket disk 41 presses the elastic pleated airbag 31.

[0032] The working principle of the concrete exterior wall screw hole plugging device provided by the utility model is as follows:

[0033] The threaded rod 2 is used to insert the contact plate 1 into the screw hole of the concrete outer wall, and the driving component 4 is used to press the elastic pleated airbag 31. Specifically, by rotating the rotating ring 44, the sliding rod 43 drives the threaded sleeve plate 41 to be screwed in along the threaded rod 2 through the sleeve 42, so that when the threaded sleeve plate 41 is screwed in along the threaded rod 2, the sleeve 42 slides along the sliding rod 43 to extend, and as the threaded sleeve plate 41 is screwed in along the threaded rod 2, the threaded sleeve plate 41 presses the elastic pleated airbag 31, and as the elastic pleated airbag 31 is compressed and radially expands and extends, the elastic storage bag 33 is also compressed and radially extended. As the outer wall of the elastic material storage bag 33 is provided with a thin bag groove 331, the outer wall of the elastic material storage bag 33 is restricted by the screw hole and the thin bag groove 331 is forced to withstand the pressure to the limit, and the thin bag groove 331 cracks, so that the foaming agent 332 in the elastic material storage bag 33 is ejected, so that the gap between the elastic pleated airbag 31 and the screw hole can be filled very quickly and cooperate with the expanded elastic pleated airbag 31 to avoid the elastic pleated airbag 31 from falling out or leaking. The expanded elastic pleated airbag 31 can completely block the screw hole, improve the sealing degree, and prevent leakage.
