Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a filling device for reserved holes in building structures. Background Technique

[0002] During the construction of high-rise and multi-storey cast-in-place buildings, measures such as cantilever unloading platforms and cantilever external frame systems are usually set up on higher floors to improve work safety and material turnover. Most of the cantilever members in the cantilever unloading platforms and cantilever external frame systems use I-beams to be tied by steel bars in the reserved holes in the floor slabs to achieve cantilever. The construction method of the reserved holes in the existing building structures is as follows: PVC pipes are pre-buried on the steel bar skeletons. After the concrete is poured and completed, the holes formed inside the PVC pipes are the reserved holes. After the cantilever members are removed later, the holes need to be filled.

[0003] After retrieval, the existing patent (publication number: CN217326611U) discloses a filling device for reserved holes in building structures, which includes an embedded casing pair (1) and a crack prevention cylinder assembly (2); the crack prevention cylinder assembly includes an upper cylinder (21), a lower cylinder (22) and crack-catching steel bars (23). The upper cylinder is a hollow cylindrical structure with openings at both the top and the bottom. The lower cylinder is a hollow cylindrical structure with an opening at the top and a closed bottom. The upper cylinder is coaxially connected above the lower cylinder by several crack-catching steel bars to form a crack prevention cylinder assembly; the embedded casing pair is a hollow cylindrical structure with openings at both the top and the bottom. The upper opening diameter of the embedded casing pair is larger than the lower opening diameter. The embedded casing pair is embedded in the building structure (3), and the crack prevention cylinder assembly is coaxially placed in the building structure. Cement mortar is filled in the crack prevention cylinder assembly and the gap between the crack prevention cylinder assembly and the embedded casing pair. The utility model can avoid the cracking and sliding of the cement mortar filled in the reserved holes.

[0004] However, in the above scheme, when the filling device is in use, it lacks the effect of strengthening and supporting the holes. When the building body undergoes thermal expansion and contraction, it will squeeze the holes, causing the holes to deform and resulting in the problem of unstable filling.

[0005] In view of this, the utility model proposes a filling device for reserved holes in building structures. Content of the Utility Model

There is a hole body 2 inside the building body 1. A support plate 3 that fits the building body 1 is arranged below the hole body 2. A first screw 4 that is screwed into the inside of the building body 1 is threadedly connected inside the support plate 3. An embedding ring 5 is arranged above the support plate 3 and fits inside the hole body 2. A retaining ring 6 is fixedly connected to the inner wall of the embedding ring 5. A bottom plate 7 fits on the top of the retaining ring 6. A second screw 14 that is screwed into the inside of the retaining ring 6 is threadedly connected inside the bottom plate 7. An inner support plate 8 fits on the inner wall of the embedding ring 5. A limiting rod 9 is fixedly connected to the tail of the inner support plate 8. A concave hole 10 is arranged inside the limiting rod 9. A screw rod 11 that is screwed into the inside of the bottom plate 7 is threadedly connected inside the concave hole 10.

[0031] In this embodiment, six groups of inner support plates 8 are arranged equidistantly about the center of the limiting rod 9. The six groups of inner support plates 8 are made of steel plates. By arranging six groups of inner support plates 8 made of steel plates, the embedding ring 5 can have better anti-extrusion ability, so as to better support the hole body 2.

[0032] In this embodiment, the six groups of inner support plates 8 are all in a tightly fitting state with the inner wall of the embedding ring 5. When the inner support plates 8 are placed into the inside of the embedding ring 5, the inner support plates 8 will fit with the inner wall of the embedding ring 5 at this time, so as to play a role in supporting the embedding ring 5 and prevent the embedding ring 5 from deforming due to extrusion.

[0033] In this embodiment, the retaining ring 6 is designed in an arc shape on the inner wall of the embedding ring 5. The bottom plate 7 forms a limiting structure through the retaining ring 6. The bottom plate 7 can seal the bottom of the hole body 2 to prevent concrete from falling from the bottom of the hole body 2.

[0034] In this embodiment, the support plate 3 is in a "cross" shape structure. The inner support plates 8 are flush with the top of the embedding ring 5. The support plate 3 can play a supporting role for the embedding ring 5, and the support plate 3 is fixed by the first screw 4. After the concrete inside the hole body 2 solidifies, the support plate 3 can be disassembled.

[0035] In this embodiment, the concave hole 10 is provided at the center of the limiting rod 9, and the screw rod 11 is completely hidden inside the concave hole 10. The fact that the screw rod 11 is completely hidden inside the concave hole 10 can enhance the integrity of the limiting rod 9.

[0036] In this embodiment, screw holes matching the second screw 14 are provided inside both the embedding ring 5 and the bottom plate 7. The bottom plate 7 forms a fixed structure through the second screw 14. The bottom plate 7 can be fixed by the second screw 14. When the opening direction of the hole body 2 is at any angle, it can prevent the bottom plate 7 from falling off the embedding ring 5.

[0037] Embodiment 2

[0038] On the basis of Embodiment 1, a preferred embodiment of a filling device for reserved holes in a building structure provided by the present utility model is as Figures 1 to 6 shown: Waterproof coiled materials 12 are attached to both the top and bottom of the embedding ring 5, and a reinforcing ring 13 is fixedly connected to the side surface of the inner support plate 8.

[0039] In this embodiment, the waterproof coiled material 12 completely wraps the hole body 2. By providing the waterproof coiled material 12, the waterproof coiled material 12 will block the hole body 2, and can prevent water from penetrating into the inside of the hole body 2 after the hole body 2 is filled.

[0040] In this embodiment, the reinforcing ring 13 and the inner support plate 8 are arranged in a cross shape, and the height of the reinforcing ring 13 is the same as that of the embedding ring 5. By providing the reinforcing ring 13, the reinforcing ring 13 and the inner support plate 8 cross each other, which can further enhance the anti-deformation ability of the inner support plate 8 and make the hole body 2 more stable after being filled.

[0041] Working principle and usage process of the utility model: First, when it is necessary to fill the hole body 2, first attach the support plate 3 to the bottom of the building body 1 and make it located below the hole body 2, and fix the support plate 3 with the first screw 4. Then, lay a set of waterproof coiled materials 12 on the support plate 3. Next, place the embedding ring 5 into the interior of the hole body 2, place the bottom plate 7 on the top of the retaining ring 6, and screw the second screw 14 into the interior of the retaining ring 6 to fix the bottom plate 7. Then, place the inner support plate 8 into the interior of the embedding ring 5. At this time, the inner support plate 8 will fit against the inner wall of the embedding ring 5 to support the embedding ring 5 and prevent the embedding ring 5 from deforming due to extrusion. At this time, the inner support plate 8 can be fixed by screwing the screw rod 11 into the bottom plate 7. Since the screw rod 11 is completely hidden inside the concave hole 10, the integrity of the limiting rod 9 can be enhanced. After the embedding ring 5 and the inner support plate 8 are fixed, pour concrete into the hole body 2 to make the interior of the hole body 2 solid and fill the hole body 2. The bottom plate 7 can prevent the concrete from falling. Finally, place a set of waterproof coiled materials 12 on the top of the embedding ring 5 and cover the waterproof coiled materials 12 with concrete again. By setting the waterproof coiled materials 12, the waterproof coiled materials 12 will cover the hole body 2 and can prevent water from penetrating into the interior of the hole body 2 after the hole body 2 is filled. By setting the reinforcement ring 13, the reinforcement ring 13 and the inner support plate 8 cross each other, which can further enhance the anti-deformation ability of the inner support plate 8 and make the hole body 2 more stable after being filled.
