Description

Technical Field

[0001] The utility model relates to the field of floor construction, in particular to a reusable floor hole hanging device. Background Art

[0002] During the construction process of a building, various holes need to be reserved on the floor, such as setting-out holes, material transfer holes, etc., and these holes need to be blocked during the later construction.

[0003] In traditional hole hanging construction, generally, a formwork plus iron wire method is used, that is, an iron wire is fixedly connected to the formwork, the formwork is blocked below the hole, the iron wire passes through the hole and is tied to a fixed object above the hole opening, and then concrete is poured into the hole. After the concrete solidifies, the formwork and the iron wire are removed. However, after removal, the iron wire will leave holes on the cast concrete, posing a leakage hazard; another hole hanging method uses steel pipes for back jacking formwork support. When the floor is too high, it is difficult to support the formwork with steel pipes for back jacking, consuming resources.

[0004] Therefore, a reusable floor hole hanging device is now proposed. Content of the Utility Model

[0005] In order to improve the problem that it is difficult to support the formwork with steel pipes for back jacking during the traditional hole hanging construction, and at the same time, there is a leakage hazard in the formwork plus iron wire method, the utility model provides a reusable floor hole hanging device.

[0006] The utility model provides a reusable floor hole hanging device, adopting the following technical scheme:

[0007] A reusable floor hole hanging device includes a floor, a hole hanging opened on the floor, and a hole hanging component installed at the hole hanging. The hole hanging component includes a baffle located at the bottom of the floor and a sleeve threadedly installed in the middle of the baffle. The middle of the sleeve is a solid structure. A screw rod is threadedly connected to the top of the sleeve. A connecting cylinder is threadedly connected to the outer surface of the screw rod. The outer surface of the bottom of the connecting cylinder is rotatably connected with an inverted U-shaped buckle. The hole hanging component further includes two support keels lapped on the hole hanging. The two support keels are respectively located on both sides of the screw rod. The inverted U-shaped buckle is located above the support keels.

[0008] By adopting the above technical scheme, by rotating the connecting cylinder 6, the inverted U-shaped buckle 7 is driven to move downward. Under the supporting action of the support keel 8, the baffle 3 stably blocks the hole hanging 2, thus facilitating the pouring of concrete into the hole hanging.

[0009] Optionally, the baffle is one of a steel plate or an aluminum alloy plate.

[0010] By adopting the above technical scheme, the baffle has a certain rigidity to ensure that the concrete pouring is not deformed under pressure.

[0011] Optionally, a screw head is welded to the upper surface of the baffle, and the screw head is threadedly connected to the inside of the sleeve.

[0012] By adopting the above technical solution, it is convenient to separate the baffle 3 from the sleeve 4 in the later stage.

[0013] Optionally, rotating rods are fixedly connected to both sides of the connecting cylinder.

[0014] By adopting the above technical solution, the arrangement of the rotating rod 10 facilitates the rotation of the connecting cylinder 6.

[0015] Optionally, a water stop plate is fixedly connected to the outer surface of the middle part of the sleeve.

[0016] By adopting the above technical solution, the arrangement of the water stop plate 11 improves the waterproof effect between the sleeve 4 and the cast concrete.

[0017] Optionally, the height of the sleeve is adapted to the thickness of the floor slab.

[0018] By adopting the above technical solution, it is ensured that the upper screw rod 5 can be smoothly removed.

[0019] Optionally, a limiting groove is formed on the upper surface of the supporting keel, a limiting block is fixedly connected to the lower surface of the inverted U-shaped buckle, and the limiting block is inserted into the inside of the limiting groove.

[0020] By adopting the above technical solution, the arrangement of the limiting groove 12 and the limiting block 13 prevents displacement between the supporting keel 8 and the inverted U-shaped buckle 7, thereby ensuring the stability of the installation of the lower baffle 3.

[0021] In summary, the present utility model has the following beneficial effects:

[0022] 1. Through the arrangement of the hole hanging assembly of the present utility model, the installation of the baffle can be realized without punching holes in the floor slab, improving the traditional hole hanging construction method that generally uses templates and iron wires. After removal, the iron wires will leave holes in the cast concrete, posing a potential leakage problem; moreover, the hole hanging assembly is easy to disassemble and install, and is not affected by the floor height, solving the problem of difficult backtop formwork support with steel pipes when the floor is too high.

[0023] 2. The baffle, screw rod, inverted U-shaped buckle, supporting keel, etc. in the hole hanging assembly of the present utility model can be reused after removal, saving resources and costs. BRIEF DESCRIPTION OF THE DRAWINGS

The hole-hanging component includes a baffle 3 located at the bottom of the floor slab 1 and a sleeve 4 threadedly installed in the middle of the baffle 3. The baffle 3 is one of a steel plate or an aluminum alloy plate, with a certain rigidity to ensure that it does not deform under the pressure of concrete pouring. A screw head 9 is welded on the upper surface of the baffle 3, and the screw head 9 is threadedly connected inside the sleeve 4. The setting of this structure facilitates the separation of the baffle 3 and the sleeve 4 in the later stage. Further, the height of the screw head 9 is not less than 5 cm, which improves the connection strength between the screw head 9 and the sleeve 4 and is not easy to fall off.

[0031] Referring to Figures 1-3 , a screw rod 5 is threadedly connected to the top of the sleeve 4, a connecting cylinder 6 is threadedly connected to the outer surface of the screw rod 5, and rotating rods 10 are fixedly connected to both sides of the connecting cylinder 6. The setting of the rotating rods 10 facilitates the rotation of the connecting cylinder 6. The outer surface of the bottom of the connecting cylinder 6 is rotatably connected to an inverted U-shaped buckle 7, and the inverted U-shaped buckle 7 is rotatably connected to the connecting cylinder 6 through a bearing. The hole-hanging component further includes two supporting keels 8 lapped on the hole for hanging 2, the two supporting keels 8 are respectively located on both sides of the screw rod 5, and the inverted U-shaped buckle 7 is located above the supporting keel 8. By rotating the connecting cylinder 6, the inverted U-shaped buckle 7 is driven to move downward. Under the supporting action of the supporting keel 8, the baffle 3 stably blocks the hole for hanging 2, thereby facilitating the pouring of concrete into the hole for hanging.

[0032] Referring to Figures 1-3 , a limiting groove 12 is opened on the upper surface of the supporting keel 8, a limiting block 13 is fixedly connected to the lower surface of the inverted U-shaped buckle 7, and the limiting block 13 is inserted into the limiting groove 12. The setting of the limiting groove 12 and the limiting block 13 prevents displacement between the supporting keel 8 and the inverted U-shaped buckle 7, thereby ensuring the stability of the installation of the lower baffle 3.

[0033] Referring toFigure 2 and Figure 3 , a water stop plate 11 is fixedly connected to the outer surface of the middle part of the sleeve 4. The setting of the water stop plate 11 improves the waterproof effect between the sleeve 4 and the cast concrete. Further, the diameter of the water stop plate 11 is greater than 70 mm to ensure the waterproof quality. At the same time, the middle part of the sleeve 4 is a solid structure to ensure that there will be no leakage from the sleeve 4 after the screw 5 is removed.

[0034] Refer to Figures 1-3 , the height of the sleeve 4 is adapted to the thickness of the floor slab 1 to ensure that the upper screw 5 can be removed smoothly.

[0035] The implementation principle of the present utility model is as follows:

[0036] First, by rotating the connecting cylinder 6, the inverted U-shaped buckle 7 is driven to move downward. Under the supporting action of the supporting keel 8, the baffle 3 stably blocks the hanging hole 2, realizing the installation of the baffle 3;

[0037] Next, concrete is poured into the hanging hole 2 to realize the plugging of the hanging hole 2;

[0038] Finally, when the concrete solidifies, the connecting cylinder 6 is rotated in the reverse direction, and the supporting keel 8 is taken out from below the inverted U-shaped buckle 7; the screw 5 is rotated to separate the screw 5 from the sleeve 4, and at the same time, the lower baffle 3 is separated from the sleeve 4 to realize recycling.
