DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0023] See also Figures 1 to 4 A side keel connector is used to connect the side keel 10 and the secondary keel 20, including a first connecting portion 31 and a second connecting portion 32 connected to each other. The side keel 10 is C-shaped, including an upper limit plate 11 provided with a limiting folded edge 111 and a lower support plate 12 opposite to the upper limit plate 11. The first connecting portion 31 is provided with a positioning groove 312, and the positioning groove 312 is plug-connected with the limiting folded edge 111. The second connecting portion 32 is provided with a connecting plate 321 for connecting the secondary keel 20.

[0024] The side keel 10 is C-shaped and rolled. The upper limit plate 11 is arranged above the lower support plate 12 and is relatively parallel to the lower support plate 12. The upper limit plate 11 is provided with a limited folding edge 111 at one end facing outward. The limited folding edge 111 is formed by bending the end of the upper limit plate 11 toward the lower support plate 12. The limited folding edge 111 extends along the length direction of the upper limit plate 11. The secondary keel 20 is arranged perpendicular to the side keel 10. The end of the secondary keel 20 is inserted into the side keel 10. The bottom surface of the secondary keel 20 is located on the lower support plate 12. The width of the lower support plate 12 is greater than the width of the upper limit plate 11, so as to increase the contact area between the secondary keel 20 and the lower support plate 12, thereby increasing the support stability of the side keel 10 on the secondary keel 20.

[0025] The connecting member 30 includes a first connecting portion 31 and a second connecting portion 32. The first connecting portion 31 is used to connect the side keel 10, and the second connecting portion 32 is used to connect the secondary keel 20. The first connecting portion 31 includes a positioning plate 311, which is vertically arranged. The positioning groove 312 is arranged on the upper end surface of the positioning plate 311. When connecting the positioning groove 312 with the limiting folding edge 111, the first connecting portion 31 needs to be inserted between the upper limit plate 11 and the lower support plate 12. In order to smoothly engage the positioning groove 312 with the limiting folding edge 111, the height of the first connecting portion 31 should be less than the height of the side keel 10, that is, the distance between the upper limit plate 11 and the lower support plate 12. In this embodiment, the two positioning plates 311 are arranged in parallel and spaced apart, and the two positioning grooves 312 are simultaneously engaged with the limiting folding edge 111 to increase the connection stability between the first connecting portion 31 and the side keel 10. The positioning groove 312 passes through the positioning plate 311 , and the positioning groove 312 can move along the limiting folding edge 111 to adjust the position of the first connecting portion 31 on the side keel 10 , thereby adjusting the connection position between the secondary keel 20 and the side keel 10 .

[0026] The secondary keel 20 is U-shaped, rolled and formed, and includes side panels 21 arranged opposite to each other; when connected to the side keel 10, the secondary keel 20 is perpendicular to the side keel 10, the end of the secondary keel 20 is inserted into the side keel 10, and the bottom of the secondary keel 20 is placed on the lower support plate 12. The second connecting part 32 includes two relatively parallel and vertically arranged connecting plates 321, and the connecting plates 321 are provided with connecting holes 323. Screws are arranged in the connecting holes 323 to connect the side panels 21 and the connecting plates 321, and fix the second connecting part 32 to the secondary keel 20. The screws are located on the side of the secondary keel 20, and the bottom surface of the secondary keel 20 can be kept flat, which is convenient for the subsequent installation and positioning of the gypsum board. The two connecting plates 321 are connected by a lap plate 322, and the lap plate 322 is mounted on the two side plates 21 of the secondary keel 20. The two connecting plates 321 are located on the outer side of the side plates 21 of the secondary keel 20. Preferably, the distance between the relative inner end surfaces of the two connecting plates 321 is the same as the distance between the outer end surfaces of the two side plates 21. When the second connecting portion 32 is connected to the secondary keel 20, the two connecting plates 321 are respectively fitted with the two side plates 21, thereby increasing the connection stability between the second connecting portion 32 and the secondary keel 20.

[0027] Furthermore, in order to enable the two side panels 21 of the secondary keel 20 to stably support the lap plate 322, a bent portion 211 is provided at the upper end of the side panel 21, and the bent portions 211 on the two side panels 21 are bent relative to each other, and the lap plate 322 is overlapped on the bent portions 211 to increase the contact area between the lap plate 322 and the side panel 21, so that the lap plate 322 can be stably placed on the two side panels 21.

[0028] The upper end surface of the lap plate 322 is not higher than the end surface where the notch of the positioning groove 312 is located, so as to ensure that when the positioning groove 312 is connected to the limiting folded edge 111, the lap plate 322 is just overlapped on the side plate 21; after the positioning groove 312 is connected to the limiting folded edge 111, the positioning groove 312 limits the displacement perpendicular to the length direction of the side keel 10 to prevent the first connecting part 31 from detaching from the side keel 10; the lap plate 322 limits the displacement in the vertical direction to prevent the positioning groove 312 from moving up and down relative to the limiting folded edge 111; in this embodiment, the upper end surface of the lap plate 322 is flush with the end surface where the notch of the positioning groove 312 is located. Based on the above structure, when the first connection part 31 is connected to the side keel 10, the first connection part 31 needs to be rotated so that the positioning groove 312 rotates from bottom to top to engage with the limiting folding edge 111. Therefore, in order to avoid interference between the bottom of the first connection part 31 and the secondary keel 20 during the rotation process, the bottom of the first connection part 31 is set to a rounded corner, specifically, the bottom end of the positioning plate 311 is set to a rounded corner. Further, near one end of the second connection part 32, the top surface of the positioning plate 311 is higher than the notch of the positioning groove 312 to prevent the positioning groove 312 from being separated from the limiting folding edge 111.

[0029] Furthermore, in order to prevent the second connecting portion 32 from being separated from the secondary keel 20 during the adjustment process, a tail plate 324 is provided on the lap plate 322, and the tail plate 324 and the first connecting portion 31 are respectively provided at two opposite ends of the lap plate 322, and the tail plate 324 is perpendicular to the lap plate 322, and the width of the tail plate 324 is smaller than the distance between the two side plates 21. When the connecting member 30 is connected to the secondary keel 20, the tail plate 324 is located between the two side plates 21, and along the width direction of the tail plate 324, limited ends 325 are provided at both ends of the tail plate 324, and the limited ends 325 are bent upward, and the distance between the two limited ends 325 is greater than the distance between the two bent portions 211 on the secondary keel 20. When installing the connecting piece 30, first connect the first connecting part 31 and the side keel 10 through the positioning groove 312, and then press down the lap plate 322 to make the tail plate 324 clamped downward between the two side plates of the secondary keel 20, and the limiting ends 325 at both ends of the tail plate 324 respectively abut against the two bent parts 211 on the secondary keel 20, thereby limiting the displacement of the lap plate 322 in the vertical direction, so as to prevent the lap plate 322 from being separated from the secondary keel 20 when the connecting piece 30 has not yet been fixedly connected to the secondary keel 20.

[0030] The first connection part 31 and the second connection part 32 are formed in one piece, and a plate is vertically arranged between the two limiting plates, and the plate is connected to the lap plate 322 to connect the first connection part 31 and the second connection part 32. Specifically, the installation method is: when connecting the secondary keel 20 and the side keel 10, first insert the end of the secondary keel 20 into the side keel 10, so that the bottom of the secondary keel 20 overlaps the lower support plate 12, and then put the two positioning plates 311 between the two side plates 21 of the secondary keel 20, move the first connection part 31 along the secondary keel 20, and rotate the first connection part 31 so that the first connection part 31 enters between the upper limit plate 11 and the lower support plate 12, and the limiting folded edge 111 is stuck in the positioning groove 312. During the rotation process, the lap plate 322 is placed on the side plate 21 On the top, the two connecting plates 321 are moved to the outside of the two side plates 21; the connecting piece 30 is moved along the length direction of the secondary keel 20 to confirm that the positioning groove 312 is stably engaged with the limiting folding edge 111 and the connecting piece 30 will not fall out, and then the secondary keel 20 is moved to adjust the connection position between the second connecting part 32 and the secondary keel 20. After determining the position, a screw is placed in the connecting hole 323 to fix the second connecting part 32 and the secondary keel 20; finally, the secondary keel 20 is moved along the length direction of the side keel 10 to determine the connection position between the secondary keel 20 and the side keel 10.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
