Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] Embodiment 1:

[0041] As Figures 1-4 shown, this embodiment provides an adjustable PVC hanging formwork tool, including a first outer cylinder 1 and a second outer cylinder 2 that are mutually clamped, and an adjusting unit sleeved in the first outer cylinder 1 and the second outer cylinder 2; wherein, N groups of adjusting units are arranged in sequence, where N is a natural number greater than or equal to 1, denoted as the first adjusting unit, the second adjusting unit,..., the Nth adjusting unit, and their outer diameters decrease sequentially from outside to inside; the inner diameter of the adjusting unit located on the outside is adapted to the outer diameter of the adjacent adjusting unit located on its inside; different numbers of adjusting units are arranged, and an overall PVC hanging formwork tool with different inner diameters can be formed, so as to adapt to the sizes of pipes passing through the floor slab.

[0042] In this embodiment, the first outer cylinder 1 and the second outer cylinder 2 are rotationally symmetric. The first outer cylinder 1 includes a first flat plate 11 and a first arc plate 12 that are fixedly connected. The first flat plate 11 is a semi-circular flat plate, and the first arc plate 12 is semi-circular; a first card slot 13 and a first snap 14 are respectively arranged at both ends of the first arc plate 12; among them, the first snap 14 is rotatably connected to one end of the first arc plate 12, and a first nut 15 is threadedly connected to one end of the first snap 14. More specifically, the first card slot 13 is fixedly connected to one end of the first arc plate 12, which is a cylindrical connecting block with a slot formed thereon, thus forming a card slot. The first snap 14 is fixedly connected to the other end of the first arc plate 12, and a first connecting slot 16 identical to the first card slot 13 is arranged at this end. The first snap 14 is rotatably connected to the slot of the first connecting slot 16. Further, the first snap 14 includes a first sleeve 141 and a first screw 142 fixedly connected to the first sleeve 141. The first sleeve 141 is vertically arranged in the slot of the first connecting slot 16 and is rotatably connected to the first connecting slot 16 by a screw 17. The first nut 15 is threadedly connected to the first screw 142 of the first snap 14.

[0043] The second outer cylinder 2 includes a second flat plate 21 and a second arc plate 22 that are fixedly connected. The second flat plate 21 is a semi-circular flat plate, and the second arc plate 22 is semi-circular; a second card slot 23 and a second snap 24 are respectively arranged at both ends of the second arc plate 22. The second snap 24 is rotatably connected to one end of the second arc plate 22, and a second nut 25 is threadedly connected to one end of the second snap 24. More specifically, the second card slot 23 is fixedly connected to one end of the second arc plate 22, and the structure of the second card slot 23 is the same as that of the first card slot 13. The second snap 24 is fixedly connected to the other end of the second arc plate 22, and a second connecting slot 26 identical to the second card slot 23 is arranged at this end. The second snap 24 is rotatably connected to the slot of the second connecting slot 26. Further, the second snap 24 includes a second sleeve 241 and a second screw 242 fixedly connected to the second sleeve 241.

[0044] By rotating the first snap 14, the first sleeve 141 can rotate around the screw 17 as an axis. When the screw 142 of the first snap 14 is inserted into the second card slot 23, rotate the first nut 15 so that the end of the first nut 15 abuts against the second card slot 23, where the diameter of the first nut 15 is greater than the height of the second card slot; the same operation is performed on the second snap 24 to insert it into the first card slot 13, and then the first outer cylinder 1 and the second outer cylinder 2 are connected.

[0045] In this embodiment, inside the outer cylinder composed of the first outer cylinder 1 and the second outer cylinder 2, multiple groups of adjusting units are arranged. By arranging different numbers of adjusting units, a PVC suspension form tool with different inner diameters can be formed as a whole, so as to adapt to the sizes of different pipes passing through the floor slab, and thus the reserved hole in the floor slab can be effectively formed for concrete pouring.

[0046] Specifically, each group of adjusting units includes two adjusting half-cylinders arranged oppositely. N groups of adjusting units are arranged in sequence, where N is a natural number greater than or equal to 1, denoted as the first adjusting unit, the second adjusting unit,..., the Nth adjusting unit, and their outer diameters decrease sequentially from outside to inside. The Nth adjusting unit includes an Nth adjusting flat plate and an Nth adjusting half-cylinder fixedly connected. The Nth adjusting flat plate is a semi-circular flat plate, and the Nth adjusting half-cylinder is a semi-circular structure. The inner diameter of the Nth adjusting half-cylinder is adapted to the outer diameter of the (N + 1)th adjusting half-cylinder. The outer contour of the Nth adjusting flat plate is flush with the outer contours of the first flat plate and the second flat plate.

[0047] In this embodiment, two groups of adjusting units are arranged, that is, N = 2. That is to say, the adjusting units in this embodiment include a first adjusting unit 3 and a second adjusting unit 4.

[0048] The first adjusting unit 3 includes a first adjusting flat plate 31 and a first adjusting half-cylinder 32 fixedly connected. The first adjusting flat plate 31 is a semi-circular flat plate, and the first adjusting half-cylinder 32 is a semi-circular structure. The outer diameter of the first adjusting half-cylinder 32 is adapted to the inner diameters of the first outer cylinder 1 and the second outer cylinder 2, that is, after assembly, the outer contours of the upper flat plates are flush. Two first adjusting units 3 are arranged and can be spliced relatively. After splicing, they are located inside the first outer cylinder 1 and the second outer cylinder 2 and are respectively abutted against them. The two first adjusting half-cylinders 32 are respectively located above the first flat plate 11 and the second flat plate 21, and their outer contours are flush. When arranging one group of adjusting units can meet the suspension form operation of the pipe, the two first adjusting half-cylinders 32 form a bottom plate for pouring concrete after splicing, and can keep the poured part flat.

[0049] The second adjusting unit 4 includes a second adjusting flat plate 41 and a second adjusting half-cylinder 42 fixedly connected. The second adjusting flat plate 41 is a semi-circular flat plate, and the second adjusting half-cylinder 42 is a semi-circular structure. Two second adjusting units 4 are arranged and can be spliced relatively. After splicing, the two second adjusting flat plates 41 are located above the two first adjusting flat plates 31, and their edges can be flush. Therefore, when arranging two groups of adjusting units, the inner diameter of the tool as a whole is suitable for the pipe. At this time, the two second adjusting flat plates 42 located at the top form a bottom plate for pouring concrete after splicing, keeping the flatness of the poured part.

[0050] The adjustable PVC suspended formwork tool provided in this embodiment, when in use, selects an appropriate number of adjusting units according to the outer diameter of the corresponding pipeline. Among them, the first adjusting half cylinders 31 of the two first adjusting units 3 abut against the inner side walls of the first outer cylinder 1 and the second outer cylinder 2, and the outer walls of the second adjusting half cylinders 41 of the two second adjusting units 4 abut against the inner side walls of the two first adjusting units 3, and so on; the two first adjusting plates 31 are respectively located above the first plate 11 and the second plate 21, and the two second adjusting plates 41 are respectively located above the two first adjusting plates 31, and so on. After being assembled, the inner diameter of the adjusting unit located at the innermost side is adapted to the outer diameter of the pipeline, that is, it just wraps around the outer wall of the pipeline; the adjusting plate located at the uppermost side serves as the bottom plate for pouring concrete at the reserved hole, which can ensure the flatness of the pouring. After installing each adjusting unit in sequence, finally, the first outer cylinder 1 and the second outer cylinder 2 are sleeved on the outermost layer, and the first buckle 13 and the second buckle 23 are respectively clamped on the second clamping groove 24 and the first clamping groove 14, the first nut 15 and the second nut 16 are tightened, and the screws at each buckle are tightened, thereby realizing the fixed connection of the first outer cylinder 1 and the second outer cylinder 2.

[0051] The adjustable PVC suspended formwork tool provided in this embodiment selects an appropriate number of adjusting units according to the outer diameter of the corresponding pipeline. After the tool is assembled, the inner diameter of the adjusting unit located at the innermost side is adapted to the outer diameter of the pipeline, that is, it just wraps around the outer wall of the pipeline; the adjusting plate located at the uppermost side serves as the bottom plate for pouring concrete at the reserved hole, which can ensure that the pouring construction surface is flat and smooth, the product is closely joined with the pipeline and the floor slab, and the mortar is not easy to leak; after construction, the wall and the pipeline are clean and tidy, and there is no need to invest in manual cleaning and grinding later. There is no need to connect with iron wire between the upper and lower layers, eliminating the potential water seepage hazard caused thereby. And the form removal time can be greatly advanced.

[0052] In the operation process of using this adjustable PVC suspended formwork tool, the construction speed is fast and the installation is extremely convenient and fast. The two half outer cylinders and the adjusting units are pre-assembled, and one person can operate independently downstairs, and a set can be installed in a few seconds. Only one person is required to operate downstairs during form removal, and the form removal is rapid. It improves the construction efficiency and saves labor input. It can be reused multiple times, there is no need to repeatedly purchase plywood and iron wire, and there is no need for carpentry production, saving material costs.
