Description

Technical Field

[0001] The utility model relates to the technical field of house construction, in particular to a blocking plate for a reserved hole in a wall. Background Art

[0002] During the construction process of a building, it is often necessary to reserve holes in the wall due to reasons such as the erection of cantilevered external frames. The holes are then filled and sealed after the frames are removed. Sealing the exterior walls of high-rise buildings is somewhat difficult. With the development of the times, sealing technology is also constantly improving. For example, the new exterior wall bolt hole sealing technology based on BIM technology outputs the required number and specifications of precast concrete cones through the BIM model, thereby improving construction efficiency and accuracy. In addition, some advanced construction techniques such as grouting and grouting are also widely used in the sealing of reserved wall openings. At the same time, wall reserved hole sealing baffles have also emerged and have been continuously developed.

[0003] For example, a Chinese patent (publication number: CN215859056U) discloses a casting structure for reserved holes in an exterior wall, wherein the outer formwork is sealed at the hole outside the reserved hole, and the inner formwork is sealed at the hole inside the reserved hole. The casting port of the inner formwork is connected to the reserved hole, and the casting assembly includes a pumping pump and a guide pipe. The inner cavity of the pumping pump is connected to the reserved hole through the guide pipe. When the pumping pump is started, the pumping pump can pump concrete into the reserved hole through the guide pipe. After the pouring is completed, the connection between the pumping pump and the guide pipe is released, and a sealing measure is taken at the pipe mouth of the guide pipe away from the inner formwork. After the concrete reaches the curing time, the inner formwork and the outer formwork are removed, and the guide pipe and the concrete in the guide pipe can be directly chiseled out, which reduces the workload of chiseling concrete in the later stage, has high construction efficiency, and good casting quality. Moreover, the inner formwork does not need to be tilted relative to the reserved hole, which makes it easier to reinforce the inner formwork and the outer formwork.

[0004] However, this device cannot guarantee construction safety, because the fixing of the formwork on the exterior wall requires manual work outside the building, which is prone to accidents and further reduces construction safety. Therefore, a baffle with a reserved hole in the wall is proposed to solve the above problem. Utility Model Content

[0024] In addition, the feed assembly 3 includes two partitions 302 that are abutted against the right side of the wall 1. The right sides of the two partitions 302 are movably connected to the feed seat 301.

[0026] In this embodiment, the feed seat 301 on the feed component 3 can ensure smooth entry of cement mortar, and at the same time, in conjunction with the stabilizing component 4 and the telescopic baffle 5, it can further improve the safety of use.

[0027] Please refer again Figure 1 and Figures 3 to 4 In order to improve the safety of the operation, the stabilizing component 4 in this embodiment includes a rotating rod 401 rotatably connected to the inner side of the feeding component 3. A hexagonal head 402 is fixed to the right side of the rotating rod 401 and to the right side of the pad 2. The hexagonal head 402 can be conveniently fixed with an electric drill, further improving the disassembly and assembly efficiency. A reversing part 403 located in the wall 1 is provided on the left side of the rotating rod 401, and a threaded rod 404 is fixed to the left side of the reversing part 403.

[0028] In addition, the left side of the rotating rod 401 passes through the pad 2 and the connecting hole in sequence and extends into the wall 1. The rotating rod 401 is rotatably connected to the connecting hole through two sealed bearings. The reversing part 403 is composed of a universal joint 4031 and a bellows 4032. The left and right sides of the universal joint 4031 are respectively fixed to the rotating rod 401 and the threaded rod 404. The universal joint 4031 can change direction at will. When the telescopic baffle 5 needs to be passed through the reserved hole, it is only necessary to rotate the telescopic baffle 5 to a horizontal state and press the two limit plates 503 to pass the telescopic baffle 5 through the reserved hole, thereby improving the user's safety.

[0029] It can be known that the telescopic baffle 5 includes a moving block 501 threaded with the threaded rod 404, a plurality of compression springs 502 are fixed on the front and rear sides of the moving block 501, the compression springs 502 are arranged to ensure that the telescopic baffle 5 is restored smoothly after the telescopic baffle 5 successfully passes through the reserved hole, and further ensure the sealing tightness of the plugging, and the opposite sides of the plurality of compression springs 502 are fixed with limit plates 503.

[0030] It should be further explained that the front and rear sides of the moving block are penetrated into the inner side of the limit plate and are fixed with stable plates, the outer side of the stable plate is penetrated into the inner wall of the limit plate and is in sliding connection with the inner wall of the limit plate, the limit plate is provided with a through hole for the moving block to penetrate, the inner wall of the limit plate is provided with a sliding groove for the stable plate to slide, the diameter of the through hole is smaller than the diameter of the stable plate, the limit block is arranged to limit the limit plate 503, so that the moving block 501 and the limit plate 503 are prevented from being completely separated, and the service life of the device is further improved.

[0031] In the embodiment, the cooperation of the universal joint 4031 and the telescopic baffle 5 can make the telescopic baffle 5 pass through the reserved hole smoothly, without manual outdoor installation, and can effectively improve the safety of the user.

[0032] It can be understood that the cooperation of the feeding assembly 3 and the stable assembly 4 can effectively improve the sealing tightness of the plugging, and the cooperation of the universal joint 4031 and the compression spring 502 can complete the plugging of the reserved hole without outdoor operation, which can effectively improve the safety.

[0033] The working principle of the above embodiment is as follows:

[0034] Before sealing the reserved hole in the wall 1, first assemble the feeding component 3, the stabilizing component 4 and the telescopic baffle 5, and pass the telescopic baffle 5 through the reserved hole. At the same time, pull the feeding component 3 toward the indoor direction with force to make the telescopic baffle 5 fit tightly with the wall 1. Then rotate the stabilizing component 4. Since the threaded rod 404 is threadedly connected with the telescopic baffle 5 and under the friction of the wall 1, the feeding component 3 is gradually approached to the wall 1 until it fits tightly with the wall 1. When the feeding component 3 fits tightly with the wall 1, insert the partition 302 to improve the stabilizing effect of the feeding component 3, and further insert the partition 303 according to the actual size of the hole. And pour cement mortar from the top of the feed seat 301, the cement mortar enters the reserved hole through the feed hole, until the cement mortar strength meets the requirements, rotate the hexagonal head 402, so as to realize the disassembly of the stabilizing component 4 and the feed component 3 together, and when the telescopic baffle 5 needs to be disassembled, the user only needs to use a longer net bag to net the telescopic baffle 5 and knock down the telescopic baffle 5 with a long rod, and finally fill the remaining holes with cement mortar to complete the sealing of the reserved hole in the wall 1 and ensure the aesthetics. The device is easy to use and safe. No need to go outdoors to complete the sealing of the reserved hole, which can greatly increase the safety of the user.
