[0024] To better understand the technical solutions of the embodiments of the present utility model, the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0025] It should be clear that the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope protected by the embodiments of the present utility model.

[0026] As Figure 1 and Figure 2 shown, an embodiment of the present utility model discloses a middle seam profile 10, which is used to connect two adjacent and parallel prefabricated bathroom wall panels 20.

[0027] The overall structure of the middle seam profile 10 is a "soil"-shaped structure. It includes a spacer 1, a first plugboard 2, a second plugboard 3 and a backplate 4.

[0028] The spacer 1 can be arranged between two adjacent prefabricated bathroom wall panels 20. It has a first connection surface 11 and a second connection surface 12 which are relatively positioned. The two side edges of the spacer 1 are respectively the first side edge and the second side edge. The first side edge is located at the lower part of the spacer 1 in Figure 1 and the second side edge is located at the upper part of the middle spacer 1 in Figure 1 the middle. A caulking adhesive connection part 13 which can contact with the caulking adhesive to improve the connection strength of the caulking adhesive is provided at the first side edge of the spacer 1. The width of the caulking adhesive connection part 13 is smaller than the width of the spacer 1.

[0029] The first plugboard 2 is vertically arranged on the first connection surface 11 of the spacer 1. The first plugboard 2 can be inserted into the vertical groove on the side wall of the prefabricated bathroom wall panel 20. A fishbone structure 21 is provided on the first plugboard 2. The fishbone structure 21 is composed of multiple grooves. The fishbone structure can accommodate the sealant. When the sealant solidifies, it can improve the connection strength between the sealant and the first plugboard​​The second plug plate 3 is vertically arranged on the second connecting surface 12 of the partition plate 1. The second plug plate 3 can be inserted into the vertical slot of the side wall of the prefabricated bathroom wall plate 20. A guide structure 31 is arranged on the free end of the second plug plate 3 for guiding the insertion of the second plug plate 3 into the vertical slot. The guide structure 31 is a structure with a tapered cross section as a whole, and the thickness decreases as it approaches the free end, so as to facilitate the insertion into the vertical slot.

[0031] The back plate 4 is a flat structure as a whole, and is vertically arranged at the second side of the partition plate 1. The back plate 4 extends to both sides from the partition plate 1. The side of the back plate 4 close to the first plug plate 2 forms a first groove 51 together with the first plug plate 2 and the first connecting surface 11; and the side of the back plate 4 close to the second plug plate 3 forms a second groove 52 together with the second plug plate 3 and the second connecting surface 12.

[0032] Referring to Figure 2 In use, the joint profile 10 is connected between two prefabricated bathroom wall plates 20.

[0033] First, the joint profile 10 is connected with the right prefabricated bathroom wall plate 20 in Figure 2 The first plug plate 2 is inserted into the vertical slot of the side wall of the prefabricated bathroom wall plate 20, and the vertical slot and the first plug plate 2 are bonded with sealant. A large amount of sealant is stored in the fishbone structure 21 on the first plug plate 2, which improves the connection effect and sealing effect of the first plug plate 2 and the prefabricated bathroom wall plate 20 after solidification. Then, the self-tapping screw 30 is struck on the back plate 4 to reliably fix the back plate 4 and the right prefabricated bathroom wall plate 20 as a whole. The prefabricated bathroom wall plate 20 is inserted into the first groove 51, and the first groove 51 can position and protect the edge of the prefabricated bathroom wall plate 20.

[0034] Then, the second plug plate 3 of the joint profile 10 is inserted into the vertical slot of the left prefabricated bathroom wall plate 20. When inserted, the guide structure 31 of the second plug plate 3 can guide the smooth insertion of the second plug plate 3. The second plug plate 3 and the vertical slot of the left prefabricated bathroom wall plate 20 are connected by sealant, which improves the connection effect and sealing effect.

[0035] After insertion, the joint 40 between the two prefabricated bathroom wall plates 20 is sealed with sealant. After the sealant enters the joint 40, it is combined with the sealant connecting part 13, which improves the connection strength of the sealant and effectively improves various problems such as cracking and falling off of the sealant.

[0036] Therefore, the middle joint profile can reliably connect two assembled bathroom wallboards 20, form mechanical sealing and connection, form double sealing with the wallboard gap, ensure the connection strength, improve the sealing and waterproof effect, improve the problem of the caulking cracking and falling, improve the installation efficiency, and ensure the connection effect.

[0037] Further, a fishbone structure 41 is arranged on the surface of the side of the back plate 4 close to the first plug-in plate 2 and facing the first plug-in plate 2, and the sealant can be applied here, so that the connection effect between the back plate 4 and the assembled bathroom wallboard 20 is improved.

[0038] The side of the back plate 4 close to the first plug-in plate 2 is provided with a screw positioning structure 42 on the surface away from the first plug-in plate 2, which can assist in positioning the self-tapping screw 30 and ensure the accurate position of the self-tapping screw 30.

[0039] The guide structure 31 of the second plug-in plate is a two-stage tapered guide structure with gradually decreasing width, so that the guide effect is improved and the structural strength is ensured.

[0040] From Figure 1 It can be known that the first side edge of the spacing plate 1 is provided with a gradually changing part 14 extending to the caulking adhesive connecting part 13 and gradually decreasing in width, the end of the gradually changing part 14 is connected with the caulking adhesive connecting part 13 and forms a containing groove containing caulking adhesive. The width of the gradually changing part 14 close to the caulking adhesive connecting part 13 is smaller than the caulking adhesive connecting part 13, so that the containing groove is formed. After the caulking adhesive enters the containing groove, the caulking adhesive connecting part 13 can be surrounded, so that the connection strength of the caulking adhesive is further improved.

[0041] The free end of the side of the back plate 4 close to the second plug-in plate 3 is provided with an expansion part 43 expanding outward, which can guide the assembled bathroom wallboard 20 to enter the second groove 52, and facilitate the installation of the assembled bathroom wallboard 20.

[0042] The embodiment of the utility model further discloses an assembled bathroom. The assembled bathroom comprises at least two adjacent and parallel assembled bathroom wallboards 20, the side wall of the assembled bathroom wallboard 20 is provided with a vertical groove, and it further comprises the above-mentioned middle joint profile 10, the first plug-in plate and the second plug-in plate of the middle joint profile 10 are respectively inserted into the vertical grooves of the adjacent side walls of two adjacent assembled bathroom wallboards, and the side of the back plate close to the first plug-in plate is fixed with the assembled bathroom wallboard through the self-tapping screw. The assembled bathroom wallboard is a magnesium crystal plate composite wallboard, and can also be other wallboards.

[0043] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of protection of the present application.
