Description

Technical Field

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

[0002] In the prior art, the nodes of the geocell are generally connected by welding, riveting, U-shaped buckle connection, etc. to connect two belts, thereby forming the node structure of the geocell.

[0003] However, the mechanical properties of the geocell nodes formed by welding and riveting are poor (for example, the tensile strength at the node is much lower than the tensile strength of the belt itself). When the geocell is subjected to a large lateral tensile force, the node is very easy to be damaged, causing the two belts at the node to separate, resulting in the overall mesh structure of the geocell being destroyed, and unable to continue to effectively constrain the filler in the cell; although the geocell node formed by connecting the two belts with a U-shaped buckle has greatly improved mechanical properties compared to the geocell node formed by welding and riveting, the U-shaped buckle is usually made of metal, and its open end is easy to scratch construction workers (such as a polyester warp knitted geocell proposed in patent document CN219621743U, the open end of the U-shaped nail buckle is not protected, and when the geocell is laid, the open end of the U-shaped nail buckle is easy to scratch construction workers).

[0004] In addition, patent document CN217203974U proposes a geocell connector, which forms a node of the geocell by interlocking two fasteners and clamping a belt body. However, the first fastener and the second fastener used therein are of different structures (the two fasteners have the characteristics of male and female buckles).

[0009] Furthermore, the limiting unit also includes a clamping portion extending along the height direction of the base, and the clamping portions are arranged on both sides of the first protrusion along the width direction of the base and on both sides of the second protrusion along the width direction of the base; when the two fasteners are buckled toward each other along the height direction of the base, the distance between the clamping portion of one fastener and the clamping portion of the other fastener is equal to twice the thickness of the belt body.

[0010] Furthermore, the plurality of limiting units are arranged in an array along the length direction of the substrate, and for any two adjacent limiting units, the two adjacent limiting units are adjacent to each other in the length direction of the substrate.

[0017] 1. A geocell with a fastener node provided by an embodiment of the present disclosure has a belt body at the node divided into a plurality of strips by slits, and the strips on both sides of the slits are in different bending shapes. When the belt body is subjected to longitudinal tension, the strip between the first convex section and the first concave section will be pressed toward the first convex section, thereby increasing the friction between the strip and the first convex section. Obviously, the greater the tension, the greater the force with which the strip will be pressed toward the first convex section, and thus the greater the friction, which is conducive to limiting the displacement of the strip along the width direction of the fastener base, so that the node of the geocell can withstand a greater tension along the length direction of the belt body; in addition, the two fasteners have the same structure, which means that only one set of molds can be designed and manufactured to produce the fasteners required for the node connection of the geocell.

After the construction personnel pull the geocell to expand into a mesh shape, the connecting piece and the connecting part are threadedly connected at the node at the edge of the geocell, and then the plug section of the fixed plug rod is inserted into the third through hole of the connecting piece and inserted into the soil below, thereby anchoring the node at the edge of the geocell in the soil below, thereby preventing the expanded geocell from retracting, and facilitating the subsequent filling of the cell;

[0019] 3. The geocell of a fastener node provided in the embodiment of the present disclosure can strengthen the transverse tensile strength and longitudinal tensile strength of the belt body itself by providing a first reinforcing rib and a second reinforcing rib.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with the embodiments and drawings. The schematic implementation mode and description of the utility model are only used to explain the utility model and are not intended to limit the utility model. It should be noted that the utility model is already in the actual development and use stage.

[0033] The nodes of existing geocells are generally connected by welding, riveting, U-shaped buckle connection, etc. to connect the two belts, thereby forming the node structure of the geocell. However, the mechanical properties of the geocell nodes formed by welding and riveting are poor. When the geocell is subjected to a large lateral tension, the node is very easy to be damaged, causing the two belts at the node to separate, resulting in the destruction of the overall mesh structure of the geocell, and it is impossible to continue to form an effective constraint on the filler in the cell; although the geocell node formed by connecting the two belts with a U-shaped buckle has a significant improvement in mechanical properties compared to the geocell node formed by welding and riveting, the U-shaped buckle is usually made of metal, and its open end is easy to scratch construction workers.

[0034] In addition, there are geocell nodes formed by two fasteners that interlock and clamp the belt body. However, the two fasteners used are of different structures (the two fasteners have the characteristics of male and female buckles). These fasteners are usually produced by injection molding. Two fasteners with different structures require two sets of molds to produce, which is costly.

[0035] The utility model provides a geocell with a fastener node, which can at least partially overcome the above technical problems, can improve the mechanical properties of the geocell node, and has the characteristics of high safety and low cost.

[0036] Embodiment 1:

[0037] Please refer to Figures 1 to 7 , in a geocell of a fastener node provided in this embodiment:

[0038] like Figure 1 As shown, for any belt body 1 of the geocell, a plurality of clamping parts 11 evenly distributed along the length direction of the belt body 1 are provided on the belt body 1, and the clamping parts 11 are composed of a plurality of mutually parallel slits 111, and the length direction of the slits 111 is parallel to the length direction of the belt body 1, and the slits 111 penetrate the belt body 1 along the thickness direction of the belt body 1;

[0039] For any node of the geocell, two fasteners 2 and a locking member are provided at the node; the fastener 2 includes a base 21, and a plurality of limit units are fixedly provided above the base 21; when the two fasteners 2 are buckled toward each other along the height direction of the base 21, the limit unit of one fastener 2 and the limit unit of the other fastener 2 are interlocked with each other; the clamping parts 11 of the two belt bodies 1 at the node overlap, and the overlapping clamping parts 11 are clamped by the two fasteners 2 between the limit unit of one fastener 2 and the limit unit of the other fastener 2; the locking member is used to lock the two fasteners 2 buckled toward each other at the node.

[0040] Preferably, the plurality of limiting units are arranged in an array along the length direction of the base 21, and any two adjacent limiting units are adjacent to each other in the length direction of the base 21. Accordingly, the structure of the mold for injection molding the fastener 2 can be simplified, thereby reducing the cost of mold manufacturing.

[0041] Specifically, the limiting unit includes a first protrusion 22 and a second protrusion 23 extending along the height direction of the base 21, and the first protrusion 22 and the second protrusion 23 are adjacent to each other in the length direction of the base 21;

[0042] When the two fasteners 2 are buckled toward each other along the height direction of the base 21, the first protrusion 22 of one fastener 2 is engaged with the first protrusion 22 of the other fastener 2, and the second protrusion 23 of one fastener 2 is engaged with the second protrusion 23 of the other fastener 2;

[0043] The slit 111 is located at a position where the first protruding portion 22 and the second protruding portion 23 are adjacent to each other.

[0044] More specifically, the first raised portion 22 includes an arc-shaped first raised section 221 and an arc-shaped first recessed section 222, and a first transition section 223 is connected between the first raised section 221 and the first recessed section 222;

[0045] The second raised portion 23 includes an arc-shaped second raised section 231 and an arc-shaped second recessed section 232, and a second transition section 233 is connected between the second raised section 231 and the second recessed section 232;

[0046] The first convex section 221 and the second concave section 232 are located on the same side of the base 21 , and the first concave section 222 and the second convex section 231 are located on the same side of the base 21 ;

[0047] When the two fasteners 2 are buckled toward each other along the height direction of the base 21, the first raised section 221 of one fastener 2 cooperates with the first recessed section 222 of the other fastener 2; the second raised section 231 of one fastener 2 cooperates with the second recessed section 232 of the other fastener 2.

[0048] Accordingly, the two belt bodies 1 at the node are clamped by two buckled fasteners 2 of the same structure, and the first protrusion 22 and the second protrusion 23 on the buckle 2 present a staggered characteristic. Correspondingly, the belt body 1 clamped between the two buckles 2 also presents a staggered shape, thereby forming a stable node structure. Specifically, the belt body 1 at the node is divided into a plurality of strips by the slit 111, and the strips on both sides of the slit 111 are in different bending shapes. When the belt body 1 is subjected to longitudinal tension (i.e., the length direction of the belt body 1), the strip located between the first raised section 221 and the first recessed section 222 will be pressed toward the first raised section 221, thereby increasing the friction between the strip and the first raised section 221. Obviously, the greater the tension, the greater the force with which the strip will be pressed toward the first raised section 221, and thus the greater the friction, which is conducive to limiting the displacement of the strip along the width direction of the base 21 of the fastener 2, so that the node of the geocell can withstand a greater tension along the length direction of the belt body 1; more specifically , when the two belt bodies 1 at the node are respectively subjected to longitudinal tension and the directions of the tension are opposite (in the geocell technology industry, the node force in this case is called the node being subjected to shear force), the strips between the first raised section 221 and the first recessed section 222 are both pressed toward the first raised section 221, and the friction forces on the two belts can be used to offset the tensions on each of them, thereby increasing the upper limit of the shear force that the node can withstand; in addition, the two fasteners 2 have the same structure, which means that only one set of molds can be designed and manufactured to produce the fasteners 2 required for the geocell node connection. Compared with the prior art, the cost of a set of molds is saved, which is beneficial to improving the economic benefits of the geocell. It should be understood that when the belt body 1 is subjected to longitudinal tension, the force conditions of the strips between the second raised section 231 and the second recessed section 232 are similar, which will not be repeated here.

[0049] Preferably, both sides of the belt body 1 are roughened, for example, a plurality of convex points, convex edges or grooves are provided on both sides in the thickness direction of the belt body 1. Thus, the friction between the belt body 1 and the buckle 2 and between the belt body 1 and the belt body 1 at the node can be enhanced, thereby further enhancing the mechanical properties of the lifting node.

[0050] Preferably, the limiting unit further includes a clamping portion 24 extending along the height direction of the base 21, and the clamping portions 24 are provided on both sides of the first protrusion 22 along the width direction of the base 21 and on both sides of the second protrusion 23 along the width direction of the base 21;

[0051] When the two fasteners 2 are buckled toward each other along the height direction of the base 21 , the distance between the clamping portion 24 of one fastener 2 and the clamping portion 24 of the other fastener 2 is equal to twice the thickness of the belt body 1 .

[0052] Accordingly, the belt body 1 at the end of the length direction of the slit 111 at the node is clamped by the clamping parts 24 of the two fasteners 2. When the belt body 1 at the node is subjected to a force forcing the belt body 1 to be wound, the belt body 1 is not easily torn into a strip shape.

[0053] More preferably, a groove 29 is formed from the bottom of the base 21 toward the first raised section 221 and the second raised section 231 .

[0054] As a result, the wall thickness of the fastener 2 can be made nearly uniform. Since the fastener 2 is usually produced by injection molding, the density, quality, and mechanical properties of each part of the fastener 2 with uniform wall thickness are consistent, which also avoids deformation such as warping of the fastener 2 during the cooling process after injection molding, thereby ensuring the quality of the fastener 2. In addition, the groove 29 can also make the connection between the filler in each cell and the fastener 2 stronger after the geocell is laid (the filler enters the groove 29), which is beneficial to avoid the geocell from being detached from the filler during use (detached along the width direction of the belt body 1).

[0055] Embodiment 2:

[0056] This embodiment is based on Embodiment 1, except that, in this embodiment:

[0057] A first mounting plate 25 and a second mounting plate 26 are respectively fixedly disposed at both ends of the base 21 along the length direction;

[0058] The first mounting plate 25 and the first protruding section 221 are located on the same side of the base 21 , and the second mounting plate 26 and the second protruding section 231 are located on the same side of the base 21 ;

[0059] The fastener 2 is provided with a first through hole 27 and a second through hole 28. The first through hole 27 penetrates the first mounting plate 25 and the first raised section 221 along the length direction of the base 21, and the second through hole 28 penetrates the second mounting plate 26 and the second raised section 231 along the length direction of the base 21.

[0060] The locking member includes two insertion rod portions 31;

[0061] When the two fasteners 2 are fastened together, for any fastener 2, the first through hole 27 of the fastener 2 is coaxial with the second through hole 28 of the other fastener 2, and the two insertion rod portions 31 are respectively inserted into the first through hole 27 and the second through hole 28 of the fastener 2.

[0062] Accordingly, by respectively inserting the two insertion rod portions 31 of the locking member into the first through hole 27 and the second through hole 28 of one of the fasteners 2 in the fastened state, the two fasteners 2 in the fastened state can be locked, thereby forming a reliable node structure. When the node is subjected to tension and / or peeling force (in the geocell technology industry, the node being subjected to tension refers to the situation where both ends of one of the belt bodies 1 at the node are subjected to the first tension, and both ends of the other belt body 1 are subjected to the second tension, and the first tension and the second tension are in opposite directions and coincide with the thickness direction of the belt body 1 at the node; the node being subjected to peeling force refers to the situation where two belt bodies 1 located on the same side of the node are respectively subjected to forces that force the two belt bodies 1 to separate and force the node to be destroyed), the insertion rod portion 31 bears the external force, thereby being able to increase the upper limit of the tension and / or peeling force that the node can withstand; preferably, the insertion rod portion 31 is made of stainless steel, so that the insertion rod portion 31 has stronger bending resistance and anti-corrosion ability.

[0063] Specifically, Figure 8 As shown, the locking member further includes a connecting portion 32, the two inserting rod portions 31 are fixedly connected to the same side of the connecting portion 32, and the two inserting rod portions 31 are parallel to each other;

[0064] The geocell further comprises a fixing assembly, which comprises a fixing rod and a connecting member 5;

[0065] One end of the connecting member 5 is threadedly connected to the connecting portion 32, and the other end of the connecting member 5 is provided with a third through hole 51;

[0066] The fixed rod includes a rod section 41 and a limiting section 42. The rod section 41 is smaller than the diameter of the third through hole 51, and the limiting section 42 is larger than the diameter of the third through hole 51. Preferably, one end of the rod section 41 away from the limiting section 42 is pointed.

[0067] Preferably, if Figure 8 As shown, the above-mentioned threaded connection is to set a screw hole on the connecting portion 32 and set a corresponding screw at one end of the connecting member 5, thereby, no protruding screw structure is presented on the geocell, thereby avoiding the protruding screw structure from causing trouble to the transportation and storage of the geocell (such as the protruding screw structure scratching the transporter, the protruding screw structure in the stacked geocell during storage damaging the belt body 1, etc.); obviously, the screw can also be set on the connecting portion 32 and the corresponding screw hole can be set at one end of the connecting member 5, and the present application does not limit this.

[0068] Since the geocell is in a folded state for a long time during storage and transportation, when laying the geocell, even if the construction workers pull it to expand it into a mesh shape, the geocell still has a strong tendency to shrink (referring to the tendency to shrink to the folded state). By setting a fixing component, after the construction workers pull the geocell to expand it into a mesh shape, the connector 5 and the connecting part 32 are threadedly connected at the node at the edge of the geocell (in this process, the construction workers hold one end of the third through hole 51 of the connector 5, and the connector 5 itself can form a force arm, which is convenient for the threaded connection between the connector 5 and the connecting part 32), and then the plug section 41 of the fixed plug rod is inserted into the third through hole 51 of the connector 5 and inserted into the soil below, thereby anchoring the node at the edge of the geocell in the soil below, thereby avoiding the shrinkage of the expanded geocell and facilitating the subsequent filling of the cell. Obviously, each node of the geocell in the expanded state can also be anchored in the soil below by fixing components, thereby further strengthening the connection between the geocell and the soil below, thereby better realizing the restraint effect on the filling in the cell.

[0069] Embodiment 3:

[0070] like Fig. 9 As shown, this embodiment is based on Embodiment 1, except that, in this embodiment:

[0071] A plurality of first reinforcing ribs 12 are sandwiched inside the belt body 1 . The first reinforcing ribs 12 are arranged along the length direction of the belt body 1 . The first reinforcing ribs 12 are steel strands or steel wires with a threaded steel structure.

[0072] Accordingly, the geocell of the fastener node provided in this embodiment has a greatly improved tensile strength of the belt body 1 in the longitudinal direction (along the length direction of the belt body 1), so that the geocell of the fastener node has a stronger tensile capacity. On the basis of the greatly improved tensile strength at the geocell node, it is ensured that the belt body 1 of the geocell itself will not be broken during use, thereby ensuring that the integrity of the geocell with a mesh structure is not destroyed; in addition, using a steel strand or a steel wire with a threaded steel structure as the first reinforcing rib 12 can make the first reinforcing rib 12 and the belt body 1 more closely combined, thereby facilitating the formation of an integral tensile belt body 1; and the first reinforcing rib 12 is arranged along the length direction of the belt body 1, which is conducive to avoiding the situation where the first reinforcing rib 12 needs to be cut off when making the slit 111, thereby reducing the difficulty of opening the slit 111 (specifically, reducing the requirements for the tool for opening the slit 111 and the force required to operate the tool).

[0073] Preferably, a plurality of second reinforcing ribs 13 are disposed inside the belt body 1, and an angle is formed between the first reinforcing ribs 12 and the second reinforcing ribs 13. αThe second reinforcing rib 13 is selected from one or more of glass fiber, carbon fiber, and braided cotton thread; wherein 70°≤ α ≤90°.

[0074] Accordingly, the geocell of the fastener node provided in this embodiment has a greatly improved tensile strength of the belt body 1 in the transverse direction (along the width direction of the belt body 1). On the one hand, when the belt body 1 is subjected to transverse tension, the second reinforcing ribs 13 can effectively prevent the belt body 1 from being torn into multiple strips (i.e., cracks appear in the length direction). On the other hand, at the end position of the length direction of the slit 111, the second reinforcing ribs 13 cut by the slit 111 can effectively prevent the slit 111 from extending further (especially when the belt body 1 at the node is pulled), thereby ensuring that the formed geocell can maintain a complete mesh structure even when it is pulled by external forces during use. Since it is inevitable to cut the second reinforcing ribs 13 when opening the slit 111, one or more of glass fiber, carbon fiber, and braided cotton thread are selected as the second reinforcing ribs 13, while improving the transverse tensile strength of the belt body 1, the difficulty of opening the slit 111 is reduced.

[0075] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
