[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes joint bolts 1 and connecting plate 2; the flange ends of several joint bolts 1 are set in concrete, and the connecting plate 2 is sleeved on several joint bolts 1;

[0028] It also includes:

[0029] The waterstop frame 3 is fixed on the concrete, and several joint bolts 1 are located inside the waterstop frame 3. The waterstop frame 3 is movably locked in the groove 4 of the connecting plate 2. By cooperating with the groove 4, the waterstop frame 3 blocks the connection gap between the connecting plate 2 and the concrete, preventing seawater from contacting the joint bolts 1 and improving the service life of the joint bolts 1. A limit frame 18 is fixed on the outer wall of the waterstop frame 3. The limit frame 18 is set to abut against the side wall of the connecting plate 2 to block the connection gap between the connecting plate 2 and the waterstop frame 3.

[0030] Water-stop pad 5 is fixed on the inner wall of the groove 4, and the top of the water-stop frame 3 is set to abut against the water-stop pad 5 to improve the sealing between the water-stop frame 3 and the connecting plate 2.

[0031] The connecting frame 6 is fixed to the bottom of the inner wall of the waterstop frame 3, and the bottom of the groove 4 is provided with a connecting groove 7. The connecting frame 6 is inserted into the connecting groove 7. The connecting frame 6 is used to increase the gradient between the connecting frame 6 and the groove 4, thereby improving the waterstop performance of the waterstop frame 3.

[0032] Nuts 8, wherein there are several nuts 8, which are threaded onto the joint bolt 1, and the nuts 8 are engaged with and abut against the connecting plate 2. A sealing component 9 is disposed on the nuts 8, and the sealing component 9 includes:

[0033] The closed ring 10 consists of several closed rings 10, which are fixed at equal intervals on the connecting plate 2. The joint bolt 1 is inserted into the closed ring 10, and the nut 8 is located inside the closed ring 10 to protect the nut 8.

[0034] The limiting groove ring 11 is a plurality of rings, which are fixed on the ring wall of the corresponding closed ring 10. The limiting groove ring 11 plays a limiting role.

[0035] A plurality of limiting caps 12 are threaded onto the ring wall of the closing ring 10, and the bottom end of the limiting cap 12 is engaged within the limiting groove ring 11. After the limiting caps 12 are installed, they are connected to the limiting groove ring 11 by welding, avoiding direct welding of the nut 8 to the connecting plate 2, thus improving the service life of the nut 8. Several protrusions 14 are fixed at equal angles on the ring wall of the limiting caps 12, and the protrusions 14 are located above the limiting groove ring 11. The protrusion 14 drives the limiting cap 12 to rotate, which facilitates the installation of the limiting cap 12 on the joint bolt 1. The ring wall of several limiting caps 12 is fixed with limiting rings 15. The limiting rings 15 are set to abut against the top of the limiting groove ring 11. The limiting rings 15 are located below the protrusion 14, which facilitates blocking the opening of the limiting groove ring 11. The top of several limiting caps 12 is provided with connection points 16. The connecting rod 17 is fixed on the corresponding connection points 16, which facilitates the connection of the limiting caps 12 on the same side and fixes the position of the limiting caps 12.

[0036] A sealing ring 13, wherein there are several sealing rings 13, which are fixed to the bottom end of the limiting cap 12. The sealing rings 13 are configured to abut against the inner wall of the limiting groove ring 11 to improve the sealing performance between the limiting cap 12 and the limiting groove ring 11.

[0037] When using this utility model, the operator first inserts the connecting plate 2 into the joint bolt 1, so that the water-stop frame 3 is inserted into the groove 4 and the connecting frame 6 is inserted into the connecting groove 7. Then, several nuts 8 are installed on the corresponding joint bolt 1, so that the nuts 8 are located in the closing ring 10, and the connecting plate 2 is fixed on the concrete. Then, the limiting cap 12 is threaded onto the corresponding closing ring 10, so that the bottom end of the limiting cap 12 is inserted into the limiting groove ring 11, and the limiting ring 15 abuts against the top end of the limiting groove ring 11. Then, the limiting cap 12 is connected to the limiting groove ring 11 by welding. Finally, the connecting rod 17 is welded to the corresponding connection point 16 to connect several limiting caps 12 on the same side together.

[0038] Compared with the prior art, the beneficial effects of this utility model are:

[0039] By inserting the water-stop frame 3 and the connecting frame 6 into the groove 4 and the connecting slot 7, the gradient structure is used to improve the sealing between the connecting plate 2 and the concrete slab, reduce the contact between the joint bolt 1 and seawater, and thus improve the service life of the joint bolt 1.

[0040] The sealing component 9 is set up to seal the nut 8 and the structural bolt by using the sealing ring 10 and the limiting cap 12 to prevent the nut 8 and the joint bolt 1 from directly contacting the seawater.

[0041] A limiting ring 15 is installed to block the top opening of the limiting groove ring 11, thereby reducing the permeability of seawater.

[0042] A limiting frame 18 is installed to block the connection gap between the connecting plate 2 and the water-stop frame 3, thereby reducing the permeability of seawater.
