Description

Technical Field

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

[0002] As a three-dimensional reticular structure material widely used in geotechnical engineering, subgrade reinforcement, slope protection and ecological treatment fields, the geocell is formed by crisscrossing high-strength polymer belts to form honeycomb units, and its three-dimensional constraint effect is used to improve the shear strength and overall stability of the soil mass. In the prior art, the node connection process of the geocell is the core link determining its mechanical properties. At present, the mainstream technology uses methods such as welding, riveting or injection part connection to fix adjacent belts at the cross nodes. For example, hot melt welding makes the surface layer of the belt melt and bond by local heating, riveting uses metal or plastic rivets to penetrate the belt to achieve mechanical locking, and injection part connection fixes the cross nodes by installing connection buckles at the cross points.

[0003] Injection part connection is a relatively common connection and fixation form. The patent application number is 2024203254899, and the patent name is a geocell with strengthened nodes, which discloses the following structural form: The geocell includes: a belt body, on which a positioning unit is arranged. The positioning unit is composed of a plurality of mutually parallel strip-shaped through holes, and the length direction of the strip-shaped through holes is parallel to the length direction of the belt body. There are multiple positioning units and they are linearly arrayed along the length direction of the belt body; a connecting piece, the connecting piece includes a first buckling piece and a second buckling piece that can be buckled towards each other, and when buckled, the first buckling piece and the second buckling piece are mutually embedded, and the positioning units of the two belt bodies at the node overlap and are clamped between the first limiting unit and the second limiting unit; the geocell also includes a locking piece for locking the first buckling piece and the second buckling piece after buckling towards each other, and the locking piece includes a first pin part and a second pin part.

[0004] In order to improve the tensile strength at the node, Patent Application No. 2024203254899 uses the cooperation of the first pin part and the second pin part to lock and limit the first buckling piece and the second buckling piece after buckling towards each other, so as to improve the anti-peeling strength. However, the use of the locking piece, although it can improve the tensile strength, requires both the first pin part and the second pin part to be accurately inserted in place during the assembly process, making the product assembly process particularly complicated and restricting the production efficiency.

[0005] Based on the above technical problems, there is an urgent need for a new type of node connection structure that can significantly improve the tensile and anti-peeling strengths of the node on the premise of avoiding damage to the performance of the belt body, while simplifying the structure, reducing the assembly difficulty, and improving the assembly efficiency.

[0032] To clearly illustrate the technical features of this solution, the following elaborates on this solution through specific implementation manners. Embodiment 1

[0033] As Figure 1-8 shown, the utility model includes a geocell body. The geocell body is composed of a plurality of strips, and the strips are locked by a plurality of locking buttons to form a plurality of cells. The locking button includes a first connecting member 1 and a second connecting member 2. The first connecting member 1 includes a first base 11, on which a plurality of first through holes 13 are arranged at intervals. A first arc-shaped supporting plate 4 is arranged below each first through hole 13. Every two adjacent first through holes 13 are separated by a first partition board 3. A first arc-shaped inserting block 5 is arranged on the top surface of each first partition board 3. First limiting projections 6 are arranged on the two side surfaces of each first arc-shaped inserting block 5.

[0034] The second connecting member 2 includes a second base 12, on which a plurality of second through holes 14 are arranged at intervals. A second arc-shaped supporting plate 10 is arranged below each second through hole 14. Every two adjacent second through holes 14 are separated by a second partition board 8. Second arc-shaped inserting blocks 9 are arranged on the top surfaces of the two side walls of the second base 12 and on the top surface of each second partition board 8. Second limiting projections 7 that cooperate with the first limiting projections 6 are arranged on the side surface of each second arc-shaped inserting block 9.

[0035] The first connecting member 1 and the second connecting member 2 are buckled. The first arc-shaped inserting block 5 is inserted into the corresponding second through hole 14 and abuts against the second arc-shaped supporting plate 10. The second arc-shaped inserting block 9 is inserted into the corresponding first through hole 13 and abuts against the first arc-shaped supporting plate 4. The first limiting projections 6 and the second limiting projections 7 are mutually engaged to achieve locking.

[0036] In this embodiment, second limiting projections 7 are arranged on the inner side surfaces of the second arc-shaped inserting blocks 9 located on the top surfaces of the two side walls, and second limiting projections 7 are arranged on the two side surfaces of the second arc-shaped inserting blocks 9 located on the top surface of the second partition board 8.

[0037] In this embodiment, as Figure 4 shown, the first limiting projection 6 is a slope structure, and the thickness of the first limiting projection 6 gradually increases from the upper part to the lower part of the first arc-shaped inserting block 5.

[0038] In this embodiment, as Figure 7 shown, the second limiting protrusion 7 is a ramp structure, and the thickness of the second limiting protrusion 7 gradually increases from the upper part to the lower part of the second arc-shaped insert block 9.

[0039] In this embodiment, the lengths of the first connecting member 1 and the second connecting member 2 are not equal, and the length of the first connecting member 1 is less than that of the second connecting member 2.

[0040] In this embodiment, the first base 11, the first arc-shaped supporting plate 4, the first partition plate 3, the first arc-shaped insert block 5, and the first limiting protrusion 6 are integrally injection-molded.

[0041] In this embodiment, the second base 12, the second arc-shaped supporting plate 10, the second partition plate 8, the second arc-shaped insert block 9, and the second limiting protrusion 7 are integrally injection-molded.

[0042] During specific use, as Figure 9 shown, a plurality of mutually parallel long strip slots 16 are pre-cut at the connection node of the strip 15. The long strip slots 16 of the two strips at the connection node are overlapped, and then the first connecting member 1 and the second connecting member 2 are buckled at the connection node. The overlapped long strip slots are clamped between the first connecting member 1 and the second connecting member 2. Multiple narrow strip edges are formed at the connection node due to the cutting of a plurality of long strip slots. Part of the narrow strip edges are pushed into the second through hole 14 by the first arc-shaped insert block 5, and the other part of the narrow strip edges are pushed into the first through hole 13 by the second arc-shaped insert block 9. The connection node is locked under the fitting action of the first limiting protrusion 6 and the second limiting protrusion 7, thereby preventing the strip at the connection node from detaching.

[0043] The utility model innovatively designs the structures of the first connecting member 1 and the second connecting member 2. Through the coordinated use of the first through hole 13, the first arc-shaped supporting plate 4, the first arc-shaped insert block 5, the first limiting protrusion 6, the second through hole 14, the second arc-shaped supporting plate 10, the second arc-shaped insert block 9, and the second limiting protrusion 7, and the locking is achieved by the mutual fitting of the first limiting protrusion 6 and the second limiting protrusion 7, thereby preventing the strip at the connection node from detaching. The tensile and peel resistance strengths at the node are significantly improved. At the same time, the structure is simplified, and the first connecting member 1 and the second connecting member 2 can be assembled by buckling, reducing the assembly difficulty and improving the assembly efficiency. Embodiment 2

[0044] As Figure 10 shown, the difference between Embodiment 2 and Embodiment 1 is that the lengths of the first connecting member 1 and the second connecting member 2 are equal.
