[0023] See also Figures 1 to 3 The utility model provides a connection assembly of a geogrid, including a connection piece, an extension piece and a connection pin 7.

[0024] The connecting member includes a connecting arm 3 and two cross arms 2, wherein the two cross arms 2 are connected by the connecting arm 3, and the two cross arms 2 are parallel to each other, the cross arm 2 has a cylindrical structure with a hollow portion, and the end of the cross arm 2 is provided with an opening connected to the hollow portion, and the cross arm 2 is provided with a first connecting hole 5 that penetrates along the thickness direction of the cross arm 2.

[0025] Optionally, the connecting arm 3 and the cross arm 2 can be made of metal, such as iron, aluminum, etc., so that the connecting piece has a certain structural strength. In addition, the connecting arm 3 and the two cross arms 2 are an integrated structure to facilitate molding and improve the connection strength.

[0026] It should be noted that the connector is used to connect with the groove 10 on the wall module 9. Specifically, the connecting arm 3 of the connector is embedded in the groove, and the two cross arms 2 are respectively exposed outside the groove. The groove 10 on the wall module is a prefabricated groove, and its shape is similar to the base plate of the connecting arm 3. When connecting, it is only necessary to embed the connecting arm 3 in the groove, and the cross arm 2 is automatically exposed outside the groove. In addition, the arc groove is generally set to an arc shape to facilitate grooving. Therefore, the connecting arm 3 is set to an arc-shaped structural member, which can be conveniently connected to the groove of the wall module on the one hand, and can also be conveniently connected to the connecting arm 3 and the connecting column of the cylindrical structure on the other hand.

[0027] The extension piece includes two extension arms 1, and the two extension arms 1 are respectively embedded in the hollow parts of the two cross arms 2 through the openings. Optionally, the extension arms 1 are made of metal, such as iron, aluminum, etc., so that the extension arms 1 have a certain structural strength. The front bottom of the extension arm 1 is provided with a card slot 4, which is used to connect with the connecting rod at the edge of the geogrid 9. The opening of the card slot 4 is inclined toward the rear and lower part of the extension arm 1, so that the connecting rod at the edge of the geogrid 9 can slide out of the card slot 4, so that the connection between the two is more stable. Specifically, the card slot 4 is a U-shaped slot, which is convenient for grooving.

[0028] When the connection assembly is in use, it is only necessary to embed the connecting arm 3 of the connecting piece into the groove of the wall module, so that the cross arm 2 and the extension arm 1 are exposed outside the groove, and then connect the slot 4 on the extension arm 1 to the connecting rod at the edge of the geogrid. This connection method is simple and has high connection efficiency.

[0029] The cross arm 2 is also provided with a plurality of second connection holes 6 penetrating along the thickness direction thereof, and the connection pin 7 sequentially penetrates the second connection holes 6 and the first connection holes 5 to connect the cross arm 2 with the extension arm 1. When the connection pin 7 is connected to different second connection holes 6, the extension arm 1 extends out of the end of the cross arm 2 by different lengths, that is, the extension length of the extension arm 1 from the end of the cross arm 2 can be adjusted. Therefore, the extension length of the extension arm 1 can be adjusted according to the spacing between the edge of the geogrid and the wall module, which is more convenient to use.

[0030] Optionally, the cross-section of the hollow portion is in the shape of a vertical bar, and the two extension arms 1 are both plate structures, thereby preventing the extension arms 1 from rotating in the hollow portion and facilitating the correspondence between the first connecting hole 5 and the second connecting hole 6, thereby facilitating the installation of the connecting pin 7.

[0031] Furthermore, the number of the second connecting holes 6 is 5-10, and the spacing between adjacent second connecting holes 6 is equal, and the spacing between adjacent second connecting holes 6 is set between 1-3 cm. For example, the number of the second connecting holes 6 can be 8, and the spacing between the second connecting holes 6 can be set to 1 cm, so as to facilitate the matching of the spacing between the edge of the geogrid and the wall module with the extended length of the extension arm 1.

[0032] Specifically, the connecting pin 7 includes a connecting rod and a limiting plate, wherein the limiting plate is fixed to one end of the connecting rod, and the outer diameter of the limiting plate is larger than the inner diameter of the second connecting hole 6, thereby preventing the connecting pin 7 from sliding out of the first connecting hole 5 or the second connecting hole 6. In addition, a through hole may be provided at one end of the connecting rod away from the limiting plate, and a vertical pin may be installed in the through hole, thereby further preventing the connecting pin 7 from sliding out of the first connecting hole 5 or the second connecting hole 6.

[0033] The above are only preferred implementations of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
