Description
Technical Field
[0001] The utility model relates to the technical field of geotechnical building materials, in particular to a split geogrid. Background Art
[0002] Geogrids are divided into unidirectional geogrids and bidirectional geogrids. The bidirectional geogrids are in a net shape. Geogrids are used for reinforcing dams and roadbeds, slope protection, reinforcing the walls of holes, and reinforcing the foundations of permanent load-bearing areas such as large airports, parking lots, and wharf freight yards. Geogrids can not only increase the bearing capacity of road foundations, extend the service life of road foundations, but also prevent the road surface from collapsing or cracking, and keep the ground beautiful and tidy. When laying bidirectional geogrids, several rolls of bidirectional geogrids are often used to lay on the ground. After laying, the longitudinal grid bars of adjacent geogrids are pulled by U-shaped nails, and then the U-shaped nails are nailed to the ground to realize the connection between adjacent two geogrids and the connection between the geogrid and the ground. When using polyester yarn bundle geogrids with wider grid bars, the parts of the longitudinal grid bars of two geogrids close to the U-shaped nails may be curled and bent after being pulled by the U-shaped nails. During construction, the curling and bending of the longitudinal grid bars at the U-shaped nails should be minimized to keep the longitudinal grid bars flat. There is an urgent need for a split geogrid that can ensure the flatness at the connection of two geogrids and is convenient to connect. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a split geogrid that can ensure the flatness at the connection of two geogrids and is convenient to connect.
[0004] To solve the above technical problem, the utility model includes a first grid and a second grid arranged at intervals. The first grid includes a plurality of first cross grid bars arranged at intervals horizontally and a plurality of first longitudinal grid bars arranged at intervals vertically. The second grid includes a plurality of second cross grid bars arranged at intervals horizontally and a plurality of second longitudinal grid bars arranged at intervals vertically. Its structural feature is that: the tops of the first longitudinal grid bar and the second longitudinal grid bar with the smallest horizontal distance are provided with a first adhesive layer and the bottoms are provided with a second adhesive layer. A first hook plate is adhesively bonded to the top of the first adhesive layer. The first hook plate includes a first horizontal plate body. Any one end of the left and right ends of the first horizontal plate body is provided with a first vertical plate body extending downward. A second hook plate is adhesively bonded to the bottom of the second adhesive layer. The second hook plate includes a second horizontal plate body with the top end abutted against the bottom end of the first vertical plate body. One end of the second horizontal plate body away from the first vertical plate body is provided with a second vertical plate body extending upward to abut against the first horizontal plate body. The minimum horizontal distance from the first vertical plate body to the second vertical plate body is greater than the maximum horizontal distance between the first longitudinal grid bar and the second longitudinal grid bar provided with the first adhesive layer and the second adhesive layer. At least two ground nails passing through the second hook plate are arranged at intervals on the first hook plate.
[0005] After adopting the above structure, the first adhesive layer and the second adhesive layer preliminarily connect the first longitudinal grid bar and the second longitudinal grid bar, and the first grid and the second grid are first preliminarily connected relatively stably through the first adhesive layer and the second adhesive layer, and then the first hook plate and the second hook plate are taken. First, the first hook plate is bonded to the top of the first longitudinal grid bar and the second longitudinal grid bar through the first adhesive layer. When positioning the position of the first hook plate before bonding, the inner side surface of the first longitudinal plate body of the first hook plate is pressed against the outer side surface of the first longitudinal grid bar or the second longitudinal grid bar, and then the first horizontal plate body is attached to the first adhesive layer; then the second hook plate is bonded to the bottom of the first longitudinal grid bar and the second longitudinal grid bar through the second adhesive layer. When positioning the position of the second hook plate before bonding, the inner side surface of the second longitudinal plate body of the second hook plate is pressed against the outer side surface of the second longitudinal grid bar or the first longitudinal grid bar, and then the second horizontal plate body is attached to the first longitudinal grid bar. On the second adhesive layer, the first adhesive layer and the second adhesive layer are used to achieve a stable connection between the first longitudinal grid bar, the second longitudinal grid bar and the first hook plate and the second hook plate. The pressing of the first hook plate and the second hook plate prevents the bending and curling of the connection between the first longitudinal grid bar and the second longitudinal grid bar, ensuring the flatness of the connection between the first grid bar and the second grid bar. Finally, the first hook plate and the second hook plate are fixed to the ground by piercing and hammering the ground nails. The overall operation is simple and convenient, and the first hook plate and the second hook plate can be quickly and conveniently connected to the first longitudinal grid bar and the second longitudinal grid bar and the first hook plate and the second hook plate are connected to the ground, and the operation is efficient. The horizontal spacing from the first longitudinal plate body to the second longitudinal plate body can effectively avoid the first longitudinal grid bar and the second longitudinal grid bar, prevent the first longitudinal grid bar and the second longitudinal grid bar from being staggered and overlapped, and the first longitudinal plate body and the second longitudinal plate body can also limit the first longitudinal grid bar and the second longitudinal grid bar.
[0006] Furthermore, the first hook plate is detachably connected to the second hook plate through an anti-slip mechanism. By providing the anti-slip mechanism, the operator can conveniently take the first hook plate and the second hook plate as a set; and can also ensure that after the first hook plate and the second hook plate are bonded to the first longitudinal grid bar and the second longitudinal grid bar, the first hook plate and the second hook plate connected by the anti-slip mechanism can stably and reliably press the first longitudinal grid bar and the second longitudinal grid bar.
[0007] Furthermore, the anti-slip mechanism includes a rotating shaft arranged on the side wall of the first hook plate, the second hook plate is provided with a boss, the rotating shaft is hinged with a claw hook that can abut against the bottom of the boss, and the anti-slip mechanism is provided with two groups and is respectively arranged on the left and right sides or the front and back sides of the first hook plate and the second hook plate. By providing the rotating shaft, the boss and the claw hook, the claw hook is rotated so that the claw hook abuts against the bottom of the boss to achieve the connection between the first hook plate and the second hook plate, and the claw hook is reversed so that the claw hook is out of contact with the bottom of the boss to separate the first hook plate from the second hook plate, so that the first hook plate and the second hook plate can be detachably connected together.
[0008] Further, the ground nail includes a stress-bearing end, at the bottom of which there is a nail body extending downward and passing through the first hook plate and the second hook plate. The diameter of the nail body is smaller than the minimum outer diameter of the stress-bearing end. At the bottom of the nail body, there is an inverted conical piercing end. The nail body is inserted with a soil-dividing plate. The lower part of the soil-dividing plate has an entering plate with an outer diameter gradually increasing from bottom to top. The maximum outer diameter of the entering plate is equal to the width of the soil-dividing plate. By providing the entering plate and the soil-dividing plate, when hammering the ground nail, if the soil is hard, the ground nail can be rotated to drive the entering plate and the soil-dividing plate to rotate, so as to stir the hard soil to loosen the soil, ensuring the smooth progress of the subsequent hammering and fixing operation of the ground nail. The shape of the entering plate can ensure the smooth entry of the soil-dividing plate into the soil.
[0009] Further, a downwardly concave groove is provided at the top of the stress-bearing end. By providing the groove, the tip of tools such as a screwdriver and a spade can be inserted into the groove by the operator, and the ground nail can be conveniently rotated by rotating the tool.
[0010] In summary, the utility model has the advantages of reasonable structure and convenient use. BRIEF DESCRIPTION OF THE DRAWINGS
