Description

Technical Field

[0001] This utility model relates to the field of water-stop screw technology, specifically a carbon fiber water-stop screw. Background Technology

[0002] In the construction industry, water-stop bolts, also known as through bolts, are required. When pouring wall panels, water-stop bolts can be used as formwork to tie the formwork. After construction is completed, the exposed bolts on the outside need to be cut off, and the part embedded in the wall remains inside the wall. At the same time, a water-stop plate is welded in the middle of the traditional water-stop bolt to prevent water from seeping into the interior of the wall along the bolts inside the wall.

[0003] The current water-stop screw rod has the following problems: (1) The cut-off part cannot be used, resulting in waste of resources and increased cost; (2) During pouring, the concrete is restricted by the limiting plate, but the limiting plate and the water-stop screw rod are only connected by threads, without additional support structure, which easily leads to the concrete squeezing the limiting plate, causing the limiting plate to shift outward, thus resulting in inconsistent concrete thickness. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a carbon fiber water-stop screw rod to solve the problems of resource waste and inconsistent casting thickness caused by existing water-stop screw rods.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A carbon fiber water-stop screw includes a screw body made of carbon fiber composite material. The middle surface of the screw body is smooth, and a sleeve is fixedly connected to the middle of the smooth part. Multiple water-stop plates are fixed on the sleeve. The outer walls on both sides of the screw body are provided with first external threads. The two ends of the screw body are provided with threaded holes, and end rods are threadedly connected through the threaded holes. The outer wall of the end rod is provided with a second external thread that matches the first external thread. The diameter of the end rod is the same as that of the screw body. A limit plate and a positioning sleeve are threadedly connected to the end rod. Tightening the limit plate can make it threadedly connected to the screw body. Multiple support rods are pivotally connected to the positioning sleeve. The ends of the support rods are rotatably connected to hooks through rotary bearings. Multiple positioning rods that match the support rods are fixed on the side of the limit plate facing the positioning sleeve, and the hooks are hung on the corresponding positioning rods.

[0007] Preferably, one end of the end rod is fixed with an insert rod, which is threadedly connected to the screw hole of the screw body.

[0008] With the above technical solution, the end rod is threaded into the screw hole of the screw body through the insertion rod thread, so that the end rod is connected to the screw body.

[0009] Preferably, the smooth portion of the screw body is coated with a nano-hydrophobic coating.

[0010] Through the above technical solution, the middle surface of the screw body is coated with a nano-hydrophobic coating, which effectively reduces the capillary water seepage path.

[0011] Preferably, the contact area between the smooth part of the screw body and the sleeve is provided with two sealing grooves, and a sealing ring is engaged in the two sealing grooves.

[0012] The above technical solution, by setting two sealing grooves and inserting sealing rings in the sealing grooves, can prevent water from seeping through the screw body.

[0013] Preferably, the outer wall of the waterstop sheet is provided with a corrugated pattern.

[0014] The above technical solution adds a corrugated pattern to the outer wall of the waterstop to enhance its bonding force with the concrete.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) After the casting is completed, the main body of the screw is embedded in the concrete, while the end rod and the limiting plate can be removed from the main body of the screw for future use, reducing material waste.

[0017] (2) During pouring, the concrete can be restricted by the limiting plate. The thickness of the wall is between the two limiting plates. The limiting plate is supported by the positioning sleeve and the support rod, which can prevent the limiting plate from shifting or bending, so that the wall thickness is consistent.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-5 A carbon fiber water-stop screw includes a screw body 1 made of carbon fiber composite material. The middle surface of the screw body 1 is smooth and coated with a nano-hydrophobic coating to effectively reduce capillary seepage paths. A sleeve 2 is fixedly connected to the middle of the smooth part, preferably welded. Multiple water-stop plates 3 are fixed on the sleeve 2. The outer walls on both sides of the screw body 1 are provided with a first external thread. The two ends of the screw body 1 are provided with screw holes 4, and end rods 5 are threadedly connected through the screw holes. The outer wall of the end rod 5 is provided with a second external thread that matches the first external thread. The diameter of the end rod 5 is the same as that of the screw body 1. An insertion rod 12 is fixed to one end of the end rod 5. The insertion rod 12 is threadedly connected to the screw hole 4 of the screw body 1. When the insertion rod 12 is fully threaded into the screw hole 4, the end rod 5 is connected to the screw body 1.

[0027] The end rod 5 is threadedly connected to a limiting plate 6 and a positioning sleeve 7. When the end rod is aligned with the screw body 1, the first external thread aligns with the second external thread. At this time, tightening the limiting plate 6 allows it to be threadedly connected to the screw body 1. Multiple support rods 8 are pivotally connected to the positioning sleeve 7, i.e., a connecting seat is fixed to the positioning sleeve. One end of each support rod is movably connected to the connecting seat via a pin, and the other end of each support rod 8 is rotatably connected to a hook 10 via a rotary bearing 9. Multiple positioning rods 11 matching the support rods are fixed to the side of the limiting plate 6 facing the positioning sleeve, i.e., a connecting plate is connected to the limiting plate 6, and the positioning rods 11 are vertically connected to the connecting plate. The hooks 10 are hung on the corresponding positioning rods 11. The hooks 10 can be rotated via the rotary bearing 9 so that they are always hung above the positioning rods 11, preventing them from falling off.

[0028] Two sealing grooves are provided at the contact point between the smooth part of the screw body 1 and the sleeve, and sealing rings 13 are engaged in the two sealing grooves. By setting two sealing grooves and engaging the sealing rings 13 in the sealing grooves, water can be prevented from penetrating through the screw body 1, thereby further improving the sealing performance.

[0029] The sleeve, the water-stop plate, the end rod, the limiting plate, the support rod, and the positioning sleeve can all be made of carbon fiber composite material, which improves strength and corrosion resistance and reduces weight.

[0030] In summary, the working principle of this embodiment is as follows:

[0031] During pouring, end rods 5 are installed at both ends of the screw body 1, and then the limiting plates 6 are screwed on. The limiting plates 6 restrict the concrete, meaning the concrete is poured between the two limiting plates 6. The thickness of the wall is defined between the two limiting plates 6. Then, the positioning sleeve 7 is screwed on so that the hook on the support rod 8 can be hung on the positioning rod 11. The positioning sleeve 7 and the support rod 8 support the limiting plates 6, thus preventing them from shifting or bending and ensuring a consistent wall thickness. After pouring, the screw body 1 is embedded in the concrete, and then the end rods 5 and the limiting plates 6 are removed from the screw body 1 for future use, reducing material waste.

[0032] Example 2

[0033] Based on Example 1, the outer wall of the waterstop 3 is provided with a corrugated pattern. Adding a corrugated pattern to the outer wall of the waterstop enhances the bonding force with the concrete.
