Description

Technical Field

[0001] This utility model relates to the field of steel wire stress corrosion testing technology, and specifically to a medium container for steel wire stress corrosion testing. Background Technology

[0002] Cables are widely used in cable-supported bridge structures such as suspension bridges, cable-stayed bridges, and suspender arch bridges, playing a crucial role in ensuring the safety of modern bridges and other large structures.

[0003] Stress corrosion, a common disease affecting cables, causes significant damage. In experimental studies of cable stress corrosion processes, because the cable is immersed in the corrosive medium, tension occurs during stress loading, leading to relative displacement between the cable and the corrosion container. This makes it easy for the corrosive medium to leak from the test setup, causing pollution of the laboratory environment. Furthermore, traditional corrosion test containers are difficult to reuse.

[0009] Preferably, each of the rods has a gradually sloping tip on its outward side, which is harpoon-shaped. The tip of the rod engages with the inclined surface of the frustum-shaped groove.

If the harpoon-shaped waterproof through-hole assembly requires the installation of a uniform cross-section steel wire, the circular rubber waterproof gasket needs to be placed on the outer surface of the uniform cross-section steel wire, and a through-hole nut is used; tightening the through-hole nut solves the problem of corrosive medium leakage. The through-hole nut can also be tightened again while tensioning the cable to prevent corrosive medium leakage. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Example 1

[0025] This embodiment proposes a medium container for stress corrosion of steel wire, such as... Figure 1-5 As shown, the system includes a corrosion container substrate 1 and two waterproof components symmetrically arranged on both sides of the corrosion container substrate 1. Through holes for accommodating steel wires 7 of uniform cross-section are provided on both sides of the corrosion container substrate 1. Each waterproof component includes a waterproof through-type assembly 2, a circular rubber waterproof gasket, and a through-type nut 3. Multiple waterproof components are arranged in pairs, uniformly along the length of the corrosion container substrate 1.

[0026] Waterproof through-type composite structure 2 is a columnar structure, such as... Figure 2 As shown, where, Figure 2 (a) is a 3D diagram. Figure 2(b) is a partial sectional view, showing a through groove larger than the through hole along the axial direction; one end of the waterproof through-hole assembly 2 is fixedly connected to one side of the corrosion container substrate 1, and the other end has multiple outwardly extending rods evenly distributed circumferentially; the outer ring of the waterproof through-hole assembly 2 is threaded; the annular rubber waterproof gasket is inserted into the through groove; the annular rubber waterproof gasket has a through hole along the axial direction to accommodate the passage of the equal-section steel wire 7, preferably, to facilitate the installation of the equal-section steel wire 7, the side wall of the annular rubber waterproof gasket has a slot to accommodate the passage of the equal-section steel wire 7, extending to the axial direction and communicating with the through hole; the through-hole nut 3 is threaded with the outer ring of the waterproof through-hole assembly 2, such as... Figure 3 As shown, where, Figure 3 (a) is a 3D diagram. Figure 3 (b) is a partial sectional view; the bottom end of the through-type nut 3 is provided with a frustum-shaped groove, the groove wall of which is a gradually sloped slope, and the sloped slope matches the tip of the rod; when the through-type nut 3 is threadedly engaged with the waterproof through-type combination structure 2, the ends of multiple rods are drawn inward due to the gradually sloped slope, so that the annular rubber waterproof pad and the steel wire 7 with equal cross section are tightly attached.

[0027] To increase compatibility, each member has a gradually sloping tip on the outward side, resembling a harpoon. The tip of the member engages with the inclined surface of the frustum-shaped groove. When the through-type nut 3 is threaded into the waterproof through-type assembly structure 2, the tips of multiple members taper inward due to the gradually sloping inclined surface.

[0028] When not conducting tests, use the closed nut 4, such as Figure 4 As shown, where, Figure 4 (a) is a 3D diagram. Figure 4 (b) is a partial sectional view; the sealing nut 4 is threaded into the waterproof through-hole assembly 2 when no test is performed, and the annular rubber waterproof gasket that is inserted into the waterproof through-hole assembly 2 does not have a through hole, such as Figure 1 and 5 As shown, where, Figure 5 (a) is the first annular rubber waterproof gasket 5. Figure 5 (b) is the second annular rubber waterproof pad 6.

[0029] To increase connection strength, a chamfer is provided at the connection between the waterproof through-type composite structure 2 and the corrosion container substrate 1. A chamfer is also provided at the connection between the rod and the other end of the waterproof through-type composite structure 2.

[0030] In this embodiment, if the waterproof through-type combined structure does not require the installation of the equal-section steel wire 7, only the second cylindrical rubber waterproof gasket 6 and the sealing nut 4 are needed. Tightening the sealing nut 4 will solve the problem of corrosive medium leakage. If the waterproof through-type combined structure requires the installation of the equal-section steel wire 7, then the first annular rubber waterproof gasket 5 needs to be placed on the outer surface of the equal-section steel wire, and a through-type nut 3 needs to be used. Tightening the through-type nut 3 will solve the problem of corrosive medium leakage. The through-type nut 3 can also be tightened again while tensioning the cable to prevent corrosive medium leakage.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
