Among them, the splicing edge 211 of the metal roof panel 210 can be inserted into the clamping groove 116 of the roofing additional layer adapter 100, and then by operating the locking member 120, the first clamping jaw 114 and the second clamping jaw 115 can clamp the splicing edge 211. The keel 300 can be placed into the corresponding installation groove 111, and then the keel 300 can be locked through the locking module 130 on the installation groove 111. Thus, the roofing additional layer adapter 100 provided by the present utility model can connect the keel 300 and the splicing edge 211 of the metal roof panel 210 of the waterproof roofing layer 200 in a clamping manner, facilitating the installation of the keel 300, being conducive to the addition of the on-site additional layer 400. At the same time, the contact between the keel 300 and the waterproof roofing layer 200 is reduced, thereby reducing the wear on the waterproof roofing layer 200 and ensuring the waterproof performance of the waterproof roofing layer 200.

[0033] Referring to Figure 1 and Figure 2 , according to some embodiments of the present utility model, the locking module 130 includes a first threaded connector 131 and a first locking nut 132. Installation holes 112 are provided on opposite side walls of the installation groove 111. The first threaded connector 131 passes through the installation holes 112. A limiting portion 133 is provided at one end of the first threaded connector 131, and the other end is screwed with the first locking nut 132. The installation groove 111 is located between the limiting portion 133 and the first locking nut 132. Among them, a through hole for the first threaded connector 131 to pass through is provided on the keel 300. With the above setting, when installing the keel 300, by tightening the first locking nut 132, the first threaded connector 131 can be fixed on the main body 110, and the first threaded connector 131 passing through the keel 300 can support the keel 300, and the side wall of the installation groove 111 can limit the position of the keel 300 in the horizontal direction.

[0034] Referring to Figure 1 and Figure 2, according to some embodiments of the present utility model, the locking module 130 includes two positioning plates 134. The installation groove 111 is located between the two positioning plates 134. The two positioning plates 134 are located between the limiting part 133 and the first locking nut 132. Positioning holes are provided on the positioning plates 134. The first threaded connector 131 passes through the positioning holes on the two positioning plates 134. The limiting part 133 and the first locking nut 132 are respectively abutted against the two positioning plates 134. Among them, a plurality of positioning teeth 1341 are provided on the positioning plates 134 in the up-and-down direction, and a plurality of tooth grooves 113 are provided on the side wall of the installation groove 111 in the up-and-down direction. The positioning teeth 1341 on the positioning plates 134 are clamped in the corresponding tooth grooves 113. Thus, after the first locking nut 132 is tightened, the positioning plates 134 are fixed on the side wall of the installation groove 111 through the cooperation of the positioning teeth 1341 and the tooth grooves 113. The first threaded connector 131 can be positioned and supported by the side walls of the positioning holes on the positioning plates 134. Through the above settings, the first threaded connector 131 can be fixed on the main body 110 more firmly.

[0035] Refer to Figure 1 and Figure 2 , according to some embodiments of the present utility model, the installation hole 112 is a strip-shaped hole extending in the up-and-down direction. The first threaded connector 131 can adjust its position up and down along the installation hole 112, and the positioning plate 134 can follow the first threaded connector 131 to adjust its position. Among them, the upper end of the strip-shaped hole is open to facilitate the installation of the first threaded connector 131 and also facilitate the disassembly and assembly of the first threaded connector 131 later.

[0036] Thus, in some embodiments, the keel 300 can be abutted against the bottom wall of the installation groove 111. For keels 300 with different thickness dimensions, the height of the through holes on the keel 300 for the first threaded connector 131 to pass through may be different. At this time, since the installation hole 112 is set as a strip-shaped hole, the installation position of the first threaded connector 131 can be adjusted according to the actual situation to successfully complete the installation of the keel 300; in some other embodiments, refer to Figure 5 , the keel 300 can be spaced from the bottom wall of the installation groove 111. At this time, the keel 300 is supported by the first threaded connector 131. By adjusting the installation position of the first threaded connector 131, the installation height of the keel 300 can be adjusted. Among them, due to the above-mentioned setting of the positioning plate 134, after the first locking nut 132 is tightened, the positioning plate 134 can effectively position and support the first threaded connector 131 so that the first threaded connector 131 is fixed on the main body 110.

[0037] Refer to Figure 1 and Figure 2, according to some embodiments of the present utility model, the first threaded connector 131 is a stud, and the limiting portion 133 is arranged as a second locking nut. Thus, by tightening the first locking nut 132 and the second locking nut, the two limiting plates and the first threaded connector 131 can be fixed on the main body 110.

[0038] It should be noted that the above-mentioned locking module 130 can also adopt other setting methods. For example, the locking module 130 includes locking bolts screwed on the opposite side walls of the installation groove 111. Then, during the installation process of the keel 300, the keel 300 is installed into the installation groove 111 and abuts against the bottom wall of the installation groove 111. Then, the locking bolts on the side wall of the installation groove 111 are tightened so that the locking bolts abut against the keel 300, thereby completing the installation and fixation of the keel 300.

[0039] Refer to Figure 1 and Figure 2 , according to some embodiments of the present utility model, the locking member 120 is a second threaded connector. The upper end of the first clamping jaw 114 is fixedly connected to the main body 110, and the second clamping jaw 115 is detachably fixed to the first clamping jaw 114 through the locking member 120. The clamping groove 116 is formed by enclosing the lower section of the first clamping jaw 114 and the lower end of the second clamping jaw 115. Thus, during the installation process of the keel 300, the second clamping jaw 115 can be brought closer to and fixed on the first clamping jaw 114 through the locking member 120, so that the splicing edge 211 of the metal roof panel 210 is firmly clamped in the clamping groove 116.

[0040] Refer to Figure 1 and Figure 2 , according to some embodiments of the present utility model, one of the first clamping jaw 114 and the second clamping jaw 115 is provided with a first positioning groove 1151 and the other is provided with a first positioning rib 1141. The first positioning rib 1141 is inserted into the first positioning groove 1151. One of the first clamping jaw 114 and the second clamping jaw 115 is provided with a second positioning groove 1142 and the other is provided with a second positioning rib 1152. The second positioning rib 1152 is inserted into the second positioning groove 1142. The locking member 120 is located between the first positioning rib 1141 and the second positioning rib 1152. With the above setting, the second clamping jaw 115 can be more firmly fixed on the first clamping jaw 114.

[0041] Refer to Figure 1 and Figure 2 , according to some embodiments of the present utility model, the locking member 120 passes through the first clamping jaw 114 and the second clamping jaw 115. Third locking nuts 140 are installed at both ends of the locking member 120. The first clamping jaw 114 and the second clamping jaw 115 are located between the two third locking nuts 140. Thus, by tightening the third locking nuts 140, the second clamping jaw 115 can be brought closer to and fixed on the first clamping jaw 114.

[0042] It should be noted that the above locking member 120 can also be arranged in other ways. For example, the locking member 120 is a bolt, and the bolt passes through the first jaw 114 and is screwed to the second jaw 115. Thus, by tightening the bolt, the second jaw 115 can be fixed to the first jaw 114.

[0043] In the specific implementation process, the keels 300 on the waterproof roofing layer 200 can be arranged in a variety of different ways. For example: Refer to Figures 3 to 5 For the waterproof roofing layer 200 with a gentle slope, multiple keels 300 can be arranged side by side. At this time, the length direction of the keel 300 can be parallel or perpendicular to the splicing edge 211; Refer to Figure 6 , for the waterproof roofing layer 200 with a large slope, it is necessary to improve the connection strength between the additional layer 400 and the waterproof roofing layer 200. At this time, all the keels 300 are arranged in a mesh cross pattern. Thus, the length direction of a part of the keels 300 is parallel to the splicing edge 211, and the length direction of the other part of the keels 300 is perpendicular to the splicing edge 211.

[0044] Refer to Figure 1 , according to some embodiments of the present utility model, the length direction of the installation groove 111 is parallel to the length direction of the clamping groove 116. At this time, the roofing additional layer adapter 100 is suitable for the installation of the keel 300 parallel to the splicing edge 211.

[0045] According to some embodiments of the present utility model, the length direction of the installation groove 111 is perpendicular to the length direction of the clamping groove 116. At this time, the roofing additional layer adapter 100 is suitable for the installation of the keel 300 perpendicular to the splicing edge 211.

[0046] Refer to Figures 3 to 6 , according to a metal planting roofing of the second aspect embodiments of the present utility model, it includes a waterproof roofing layer 200, at least two keels 300, the above-mentioned roofing additional layer adapter 100 and at least one additional layer 400. The waterproof roofing layer 200 includes metal roofing panels 210 laid side by side in the left - right direction. The left and right ends of the metal roofing panels 210 have splicing edges 211 protruding upwards, and the adjacent two splicing edges 211 on the adjacent two metal roofing panels 210 are hermetically connected; the keels 300 are located on the upper side of the waterproof roofing layer 200; the roofing additional layer adapter 100 is arranged between the keels 300 and the waterproof roofing layer 200; the additional layer 400 is placed on the keels 300, and at least one additional layer 400 is a planting layer; wherein, the roofing additional layer adapter 100 clamps the corresponding two adjacent splicing edges 211 through the clamping groove 116, the keel 300 is placed in the corresponding installation groove 111 and locked by the corresponding locking module 130, and there is a gap between the keel 300 and the splicing edge 211.

[0047] For the metal planting roof provided by the present utility model, during the process of installing the additional layer 400, the splicing edge 211 of the metal roof panel 210 can be inserted into the clamping groove 116 of the roof additional layer adapter 100, and then by operating the locking member 120, the first clamping jaw 114 and the second clamping jaw 115 clamp the splicing edge 211. The keel 300 can be placed into the corresponding installation groove 111, and then the keel 300 is locked by the locking module 130 on the installation groove 111. Thus, the roof additional layer adapter 100 connects the keel 300 and the splicing edge 211 of the metal roof panel 210 of the waterproof roof layer 200 in a clamping manner, facilitating the installation of the keel 300, being conducive to the installation of the on-site additional layer 400. At the same time, the contact between the keel 300 and the waterproof roof layer 200 is reduced, thereby reducing the wear on the waterproof roof layer 200, ensuring the waterproof performance of the waterproof roof layer 200, and forming a gap between the additional layer 400 and the waterproof roof layer 200, which is conducive to the discharge of hot air and the volatilization of water vapor, improving the dryness of the roof system and not affecting the drainage function of the metal roof system.

[0048] Referring to Figure 3 and Figure 6 , in some embodiments, the additional layer 400 is composed of multiple plate units 410, and these plate units 410 are laid on the keel 300 one by one.
