Technical Field

[0001] The utility model relates to the technical field of geocells, in particular to a geocell node connection structure. Background Art

[0002] Geocell is a geotechnical reinforcement material with a honeycomb structure formed by strong connections of high-strength ribs. It is flexible and can be folded up during transportation. It can be opened and filled with soil, concrete or other fillers during use to form a structure with strong lateral restraint and rigidity. It can be used as a cushion to increase the bearing capacity of soft foundations, or it can be laid on slopes to form slope protection structures, and it can also be used to build retaining structures, etc.

[0003] With the widespread application of geocells in the field of reinforcement, the requirements for the mechanical indicators of plastic geocell nodes are getting higher and higher. The geocells connected by traditional U-shaped steel nails not only have low peel strength and shear strength of the nodes, but also the plug-in U-shaped steel nails are easily corroded, causing the nodes to spread apart, and losing the basic function of the geocell to prevent the side limit of the filler. Therefore, improving the corrosion resistance of geocell node plug-ins and significantly improving the peel strength and shear strength of plug-in plastic geocell nodes are technical problems that need to be solved urgently today.

[0004] Invention patent CN104389303A discloses a geocell with a special connection, which realizes the connection of the node position through a U-shaped double-head plug-in, but the connection strength is low and it is easy to separate under force. Utility Model Content

[0033] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0034] Embodiment 1:

[0035] like Figures 1 to 13 As shown, a geocell node connection structure of the utility model includes a connection component and two sheets 1. The two sheets 1 are bonded together at the connection to form a double-layer sheet. Both sheets 1 are long thin sheet structures with the same width. The double-layer sheet positions formed at the connection are connected through the connection component.

[0036] The double-layer sheet is provided with at least two connecting parts arranged along the length direction of the sheet 1, so that two connections at two locations of the double-layer sheet are achieved through the two connecting parts arranged in the length direction, thereby improving the connection effect.

[0037] The connection portion is provided with a plurality of dividing slits, which extend along the length direction of the sheet 1, and the plurality of dividing slits of each connection portion are arranged along the width direction of the sheet 1, so that the connection portion is divided into a plurality of small pieces 2 arranged along the width direction of the sheet 1 by the plurality of dividing slits, and each small piece 2 has a uniform width.

[0038] The small pieces 2 are convex outwards to form a receiving space inside, and the convexity is an arc-shaped structure. The adjacent small pieces 2 in the connecting part are convex in opposite directions to the two sides of the double-layer sheet 1 respectively, so that the multiple receiving spaces form a through space 3 that penetrates along the width direction of the sheet 1; Figure 6 As shown, Figure 6 Two through spaces are provided in the middle and arranged along the length direction of the sheet 1.

[0039] In this embodiment, there are two connecting parts, and the number of small pieces 2 of the two connecting parts is equal and corresponding, so the small pieces 2 of the two connecting parts correspond to each other. In this embodiment, the corresponding small pieces 2 of the two connecting parts protrude to the same side, such as Figure 2 As shown, it can be clearly seen that the top small pieces of the two connecting parts are both bulged to the right, and the second small pieces are both bulged to the left.

[0040] The connection assembly includes a plug-in 7 and connection plates 4 located on both sides of the double-layer sheet. The connection plates 4 are rectangular plates and their width is not less than the width of the sheet 1. The connection plates 4 are provided with a plurality of connection blocks 5 extending to the accommodation space. If any small sheet 2 protrudes to one side, the back side of the protruding direction is provided with a connection block 5 located on the connection plate 4. Figure 4 , 5 As shown, the connection blocks 5 on the two connection plates 4 are arranged alternately up and down.

[0041] The connecting plate 4 is provided with a groove 8 adapted to the outward protrusion of the small piece 2. In this way, the protrusion on the small piece 2 is avoided, making it easier for the connecting plate 4 to fit the double-layer sheet. Figure 4 , 5 As shown, the grooves 8 on the two connecting plates 4 are arranged alternately up and down.

[0042] The connection block 5 is provided with a socket 6. The connection block 5 is provided in the accommodation space. The connection block 5 may be a separate integral structure, or may include two blocks, both of which are provided with a socket 6. In this embodiment, the connection block is a separate integral structure.

[0043] The plug-in 7 includes at least two plug-in shafts 71. In this embodiment, since two connecting parts are provided, that is, there are two through spaces 3, two plug-in shafts 71 are provided. The plug-in shaft 71 is inserted into the through space 3 of the connecting part and extends through all corresponding sockets 6 in the through space.

[0044] like Figure 7 As shown, the lower end of the plug shaft 71 is provided with an anti-falling portion 73, the outer diameter of the anti-falling portion 73 is larger than the outer diameter of the plug shaft 71, and the front end of the anti-falling portion 73 is conical, and a notch 74 is provided on the anti-falling portion 73. The outer dimensions of the upper end of the plug shaft 71 are larger than the diameter of the socket 6, so that the plug shaft 71 is limited after being inserted into the socket 6. In this embodiment, the upper ends of the two plug shafts 71 are fixedly connected by a connecting rod 72. In other implementations of this embodiment, the upper ends of the two plug shafts 71 are not connected, and the outer dimensions of the upper end of the plug shaft 71 are larger than the diameter of the socket 6.

[0045] The thickness of the connecting block 5 is equal to the width of the small piece 2, so after the connecting block 5 is inserted between two adjacent small pieces 2, it plays a limiting role.

[0046] The end of the connecting block 5 is arc-shaped so as to fit the shape of the protrusion.

[0047] Embodiment 2:

[0048] like Figure 8-13 As shown,

[0049] The connecting parts are provided with two, the number of small pieces 2 of the two connecting parts is equal and they are arranged correspondingly, and the adjacent small pieces 2 of the connecting parts are convex in opposite directions, such as Fig.12 As shown, the same small piece 2 is convex in opposite directions in the two connecting parts, and the rest is implemented in the same way as in the first embodiment.

[0050] Embodiment 3:

[0051] The connection part of this embodiment is provided with a through space 3 that passes through the width direction of the sheet 1 through which a plurality of accommodating spaces are formed; the connection component includes a plug-in 7 and a connection plate 4 located on both sides of the double-layer sheet, the connection plate is provided with a plurality of connection blocks 5 extending to the accommodating space, the connection block 5 is provided with a socket 6, the plug-in 7 includes an insertion shaft 71, the insertion shaft 71 is inserted into the through space 3 of the connection part and passes through all corresponding sockets 6 extending into the through space.
