[0002] In current building engineering, due to the requirements of some buildings, it is necessary to drill holes in the built floor slabs. Drilling operations are inevitably carried out in basic building engineering. After the construction is completed, the holes need to be filled. However, when drilling the holes, the floor slabs are drilled through, so it is more troublesome to fill them. If only one side is filled, there will be defects on the other side. If both sides are filled simultaneously, the labor cost will increase. Some hole filling devices for building engineering cannot protect the pipe bodies when sleeving the pipe bodies.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-5 , the present utility model provides a technical solution: a hole filling device for building engineering, including an upper cover plate 1 and a lower cover plate 2. A spring 3 is fixedly connected to the inner sides of the upper cover plate 1 and the lower cover plate 2. The spring 3 is fixedly connected to a fixed piece 4. The springs 3 are evenly distributed at the bottom end of the fixed piece 4. The fixed piece 4 is fixedly connected to a sleeve fixing structure 5. An arc ring 6 is fixedly connected to the upper end of the upper cover plate 1. Two slide bars 7 are fixedly connected to the lower end of the upper cover plate 1. The two slide bars 7 are respectively fixed on the left and right sides of the upper cover plate 1. A set of card teeth 8 are fixedly connected to the far ends of the two slide bars 7 away from each other. Upper fixing blocks 9 are fixedly connected to the left and right ends of the upper cover plate 1. The two slide bars 7 respectively penetrate to the lower sides of the two upper fixing blocks 9. Lower fixing blocks 10 are fixedly connected to the left and right ends of the lower cover plate 2. The two lower fixing blocks 10 respectively correspond to the upper fixing blocks 9. When the pipe body is sleeved, as the spring 3 is deformed by force, the internal force of the upper cover plate 1 and the lower cover plate 2 becomes more uniform, protecting the pipe body. After the upper cover plate 1 and the lower cover plate 2 are connected, the lower end of the upper cover plate 1 will fit with the upper end of the pipeline.

[0020] Rotating shafts 11 are rotatably connected to the front and rear inner walls of the two lower fixing blocks 10. The front ends of the two rotating shafts 11 respectively penetrate to the front sides of the two lower fixing blocks 10. Rotating blocks 12 are fixedly connected to the front ends of the two rotating shafts 11. Clamping bars 13 are fixedly connected to the upper ends of the two rotating shafts 11. The two clamping bars 13 are respectively clamped with the two sets of teeth 8. When the sliding bar 7 penetrates through the lower fixing block 10, the teeth 8 cause the clamping bars 13 to rotate through the rotating shafts 11. When the sliding bar 7 cannot move downward, it indicates that the upper cover plate 1 and the lower cover plate 2 are connected, and the clamping bars 13 will be clamped in the teeth 8. When the sliding bar 7 moves upward, because the clamping bars 13 are stuck in the teeth 8, the left ends of the clamping bars 13 will be connected to the left inner wall of the lower fixing block 10, thus restricting the sliding bar 7 from moving upward. It is necessary to push the rotating block 12 upward to make the rotating shaft 11 rotate clockwise following the rotating block 12, and at the same time the clamping bar 13 also rotates. When the clamping bar 13 rotates and is not connected to the teeth 8, the upper cover plate 1 and the lower cover plate 2 can be separated.

[0021] Inside the sleeve fixing structure 5, a limiting block 501, a rubber sealing ring 502, an outer wall hot melt adhesive 503 and a sleeve pipe 504 are sequentially arranged. Limiting blocks 501 are fixedly connected to both sides of the rubber sealing ring 502. The limiting blocks 501 are evenly distributed on both sides of the rubber sealing ring 502. A sleeve pipe 504 is fixedly connected to one side of the rubber sealing ring 502. An outer wall hot melt adhesive 503 is fixedly connected to the top of the sleeve pipe 504. The cross-section of the outer wall hot melt adhesive 503 is lower than the highest point of the sleeve pipe 504. Through the arrangement of fixing the rubber sealing ring 502 by the limiting blocks 501, the sealing performance inside is greatly improved. At the same time, through the arrangement of the outer wall hot melt adhesive 503, the external connectivity is significantly improved. Thus, the sealing function of this device is realized.

[0022] Fixed shafts 14 are fixedly connected between the front and rear inner walls of the lower fixing block 10. The two fixed shafts 14 are respectively located above the clamping bars 13.

[0023] The shapes of the teeth 8 are all right-angled triangles.

[0024] Working principle: When the slider 7 penetrates through the lower fixed block 10, the locking teeth 8 will cause the locking bar 13 to rotate through the rotating shaft 11. When the slider 7 cannot move downward, it indicates that the upper cover plate 1 and the lower cover plate 2 are connected. The locking bar 13 will be clamped in the locking teeth 8. When the slider 7 moves upward, because the locking bar 13 is clamped in the locking teeth 8, the left end of the locking bar 13 will be connected to the left inner wall of the lower fixed block 10, thereby restricting the slider 7 from moving upward. It is necessary to push the rotating block 12 upward to make the rotating shaft 11 rotate clockwise following the rotating block 12, and at the same time the locking bar 13 also rotates. When the locking bar 13 rotates and is not connected to the locking teeth 8, the upper cover plate 1 and the lower cover plate 2 can be separated. When the pipe body is sleeved, as the spring 3 is deformed by force, the force inside the upper cover plate 1 and the lower cover plate 2 becomes more uniform, protecting the pipe body. After the upper cover plate 1 and the lower cover plate 2 are connected, the lower end of the upper cover plate 1 will fit against the upper end of the pipeline.
