Description

Technical Field

[0001] The utility model relates to the technical field of geogrids, in particular to a geogrid with a stable structure. Background Art

[0002] Geogrids are made of high molecular weight polymers such as polypropylene and polyvinyl chloride through thermoplasticization or molding to form a two-dimensional grid or a three-dimensional grid screen with a certain height. When used in civil engineering, they are called geogrids. During the manufacturing process, the polymer molecules of plastic geogrids rearrange and orient themselves during the heating and elongation process, strengthening the connection between the molecular chains and achieving the purpose of improving their strength. Their elongation is only 10% to 15% of the original sheet. If anti-aging materials such as carbon black are added to the geogrid, it can be made to have better acid and alkali resistance, corrosion resistance, and aging resistance.

[0003] Chinese patent publication number CN214573846U discloses a reinforced pressure-resistant geogrid, which includes a frame bar, the number of which is two, a transverse rib is provided between the two frame bars, the two ends of the transverse rib are respectively fixedly connected to the frame bar, and the number of the transverse ribs is several. This reinforced pressure-resistant geogrid is provided with transverse ribs, longitudinal ribs, anchor ribs and reinforcing ribs, and the reinforcing ribs can prevent the geogrid from being damaged due to stretching, thereby greatly improving the tensile resistance of the geogrid and greatly improving the geogrid. The pull-out coefficient of the grid in the soil structure improves the stability of the soil structure. The transverse convex bars, longitudinal convex blocks and anchor convex blocks increase the contact area between the geogrid and the construction layer after the geogrid is buried in the construction layer, thereby enhancing the reinforcement effect of the geogrid. The transverse convex bars greatly improve the strength of the transverse ribs, thereby improving the overall strength of the geogrid. The geogrid in the above technical solution is a fixed structure, which is very inconvenient to transport and lay, and has poor flexibility. For this reason, the utility model discloses a structurally stable geogrid for solving the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a geogrid with a stable structure to solve the problem in the above background technology that the traditional geogrid is a fixed structure, which is very inconvenient to transport and lay and has poor flexibility.

[0005] To achieve the above objectives, the present invention solves the above technical problems as follows:

[0008] As a further solution of the present invention, the lowest end of the long bolt is threadedly connected to a stud, and an end of the stud away from the limiting nut is provided with a cone thorn.

[0009] As a further solution of the present invention, the locking assembly includes a guide cylinder fixed on the lower side of the longitudinal grating plate and a lock hole located on the transverse grating plate, a piston plate is slidably sleeved in the guide cylinder, a guide rod is fixedly connected to the upper side of the piston plate, the top end of the guide rod passes through the guide cylinder and the longitudinal grating plate and is fixedly connected to an L-shaped rod, a spring is sleeved on the outside of the guide rod and located between the piston plate and the top wall of the guide cylinder, and the guide rod extends into the lock hole at one end away from the piston plate.

[0010] As a further solution of the present invention, one end of the longitudinal grating plate and the transverse grating plate are both provided with an L-shaped structure, one side of the L-shaped structure of the longitudinal grating plate is fixedly connected to two clamping plates, and the end side of the transverse grating plate away from the L-shaped structure is fixedly connected to two clamping plates, and the ends of the two adjacent clamping plates away from each other are fixed with hooks.

DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the embodiments.

[0028] See also Figure 1-6 The utility model provides a geogrid with a stable structure, including a longitudinal grid plate 1 and a transverse grid plate 2. Several of the longitudinal grid plates 1 are arranged at equal intervals, and several of the transverse grid plates 2 are arranged at equal intervals. The longitudinal grid plates 1 and the transverse grid plates 2 are staggered with each other.

[0029] Specifically, the staggered arrangement of the grid plates increases the load-bearing area of ​​the geogrid, allowing the geogrid to withstand a greater load. Moreover, due to the regular staggered arrangement of the grid plates, the geogrid can be folded, which reduces the space occupied and facilitates transportation and storage.

[0030] Furthermore, the two adjacent longitudinal grating plates 1 and the two transverse grating plates 2 together form a parallelogram structure, and one end of the longitudinal grating plate 1 and the transverse grating plate 2 is provided with an L-shaped structure, and one side of the L-shaped structure of the longitudinal grating plate 1 is fixedly connected to two clamping plates 5, and the end side of the transverse grating plate 2 away from the L-shaped structure is fixedly connected to two clamping plates 5, and the ends of the two adjacent clamping plates 5 away from each other are fixed with hooks 51.

[0031] Specifically, when connecting adjacent geogrids, the L-shaped structure can ensure that the adjacent geogrids can be located in the same plane, which not only facilitates the installation process, but also provides additional support points, making the geogrid more stable when subjected to pressure and tension.

[0032] Furthermore, the longitudinal grid plate 1 and the transverse grid plate 2 are both provided with a slot 6 at one end away from the clamping plate 5, and the width of the slot 6 is smaller than the spacing between adjacent clamping hooks 51;

[0033] Specifically, since the width of the slot 6 is smaller than the spacing between the hooks 51, the hooks 51 are not easy to fall out after being inserted into the slot 6, which increases the overall structural stability of the geogrid and can quickly connect multiple geogrids together, thereby improving the efficiency and speed of construction. Conversely, by compressing the distance between adjacent hooks 51 to shorten the distance, the adjacent geogrids can be easily separated.

[0034] Furthermore, the clamping plate 5 and the column head 35 are respectively located on both sides of the grid structure formed by the longitudinal grid plate 1 and the transverse grid plate 2;

[0035] Specifically, the stud 35 can not only prevent the nut from being stripped, but also improve the grip of the geogrid with the aid of the cone thorns 36. The hook 51 on the clamping plate 5 can prevent adjacent geogrids from separating, thereby connecting multiple geogrids into one, enhancing the overall effect. During civil engineering construction, the clamping plate 5 is arranged on the upper side of the geogrid to facilitate the disassembly and assembly process. It is worth noting that the longitudinal grid plate 1 and the transverse grid plate 2 are made of plastic material. The clamping plate 5 and the hook 51 can be made of a plastic material with a certain degree of elasticity.

[0036] Furthermore, the staggered positions of the longitudinal grid plate 1 and the transverse grid plate 2 are connected by a positioning assembly 3, and the positioning assembly 3 includes a first countersunk hole 31 located on the longitudinal grid plate 1 and a second countersunk hole 32 located on the transverse grid plate 2. A long bolt 33 passes through the first countersunk hole 31 and the second countersunk hole 32, and the bottom of the long bolt 33 is threadedly connected to a limit nut 34;

[0037] Specifically, through the cooperation of the first countersunk hole 31 and the second countersunk hole 32, the relative position between the longitudinal grid plate 1 and the transverse grid plate 2 can be accurately positioned to prevent the two from separating and ensure the stability of the structure. On the other hand, the first countersunk hole 31 and the second countersunk hole 32 can avoid the exposure of the ends of the long bolts 33 and the limiting nuts 34.

[0038] Furthermore, the lowest end of the long bolt 33 is threadedly connected to a stud 35 , and an end of the stud 35 away from the limiting nut 34 is provided with a cone thorn 36 .

[0039] Specifically, the spikes 36 can increase the friction between the geogrid and the soil, improve the grip of the geogrid at the construction site, and prevent the geogrid from sliding or shifting. After tightening the column head 35, the column head 35 and the limiting nut 34 are frictionally pressed to prevent the limiting nut 34 from loosening easily.

[0040] Further, the outermost two longitudinal grid plates 1 and the adjacent transverse grid plate 2 are detachably connected with a locking assembly 4, the locking assembly 4 comprises a guide cylinder 41 fixed on the lower side of the longitudinal grid plate 1 and a lock hole 42 on the transverse grid plate 2, a piston plate 43 is slidably sleeved in the guide cylinder 41, the upper side of the piston plate 43 is fixedly connected with a guide rod 44, the top end of the guide rod 44 penetrates through the guide cylinder 41 and the longitudinal grid plate 1 and is fixedly connected with an L-shaped rod 45, the outer side of the guide rod 44 and between the piston plate 43 and the top wall of the guide cylinder 41 is sleeved with a spring 46, the end of the guide rod 44 away from the piston plate 43 extends into the lock hole 42;

[0041] Specifically, when the geogrid needs to be unfolded, the L-shaped rod 45 is pulled upwards to drive the piston plate 43 to compress the spring 46, so that the guide rod 44 moves upwards, when the end of the L-shaped rod 45 is aligned with the lock hole 42, the L-shaped rod 45 is released, due to the elastic force of the spring 46, the guide rod 44 will quickly reset, and the end away from the piston plate 43 will be inserted into the lock hole 42, thereby locking the perpendicular state of the longitudinal grid plate 1 and the transverse grid plate 2, when the geogrid needs to be folded, the guide rod 44 is released by operating the L-shaped rod 45, so that it is withdrawn from the lock hole 42, thereby releasing the locking state, facilitating the folding and transportation of the geogrid.

[0042] Working principle:

[0043] In use, first, the folded geogrid is pulled to the state that the longitudinal grid plate 1 and the transverse grid plate 2 are perpendicular to each other, the L-shaped rod 45 is pulled upwards to drive the piston plate 43 to compress the spring 46, then the L-shaped rod 45 is released after being rotated to the state that the end thereof is aligned with the lock hole 42, the end of the L-shaped rod 45 will be inserted into the lock hole 42, so that the longitudinal grid plate 1 and the transverse grid plate 2 can maintain the perpendicular state, then the two clamping plates 5 of the adjacent geogrid are aligned and inserted into the clamping groove 6, under the action of the pressure, the clamping plate 5 deforms and passes through the clamping groove 6 and resets, the clamping hook 51 can prevent the adjacent geogrids from being separated from each other, and can connect multiple geogrids into one, thereby improving the overall effect.
