Description

Technical Field

[0001] This invention relates to the field of geogrid construction technology, and more specifically, to a vertical geogrid tensioning device with tension monitoring and a construction method thereof. Background Technology

[0002] Geogrids are widely used in the construction of soil structures such as retaining walls. They enhance the bearing capacity, improve stability, and extend the service life of soil structures. During construction, they require flat, wrinkle-free laying, maximal tension, and fixation with nails. Chinese Patent CN211898531U discloses a geogrid tensioner for use in retaining wall construction. It includes horizontal bars with several hooks spaced apart on them. These hooks are connected to the geogrid. Applying force to the bars results in a relatively uniform tension transmitted to the geogrid. A tension gauge facilitates accurate prestressing by operators, further improving the prestressing effect. While this geogrid tensioner achieves uniform tension, it is difficult for operators to apply force to the bars during construction, thus requiring further optimization and improvement. Summary of the Invention

[0003] To address the aforementioned problems, one objective of this invention is to provide a vertical geogrid tensioning device and construction method with tension monitoring. This device allows operators to quickly and stably apply tension force to the geogrid, thereby improving the efficiency of geogrid tensioning construction.

[0004] This invention provides a vertical geogrid tensioning device with tension monitoring, comprising:

[0005] Upright pole, triangular base, swing arm, linkage mechanism, and tensioning seat;

[0006] The upright is mounted on a triangular base. The swing arm and the linkage mechanism are rotatably connected to the upright. One end of the linkage mechanism is connected to the swing arm, and the other end is connected to the tensioning seat. The tensioning seat is used to hook with the geogrid. The swing arm swings to drive the linkage mechanism to move the tensioning seat and tension the geogrid.

[0007] Preferably, the vertical geogrid tensioning device with tension monitoring also includes a footplate connected to the triangular base.

[0008] Preferably, in the vertical geogrid tensioning device with tension monitoring, the bottom of the triangular base and the pedal is provided with several protruding nails; the nails are located at the part of the triangular base or pedal that contacts the ground.

[0009] Preferably, in the vertical geogrid tensioning device with tension monitoring, the triangular base includes a vertical plate and an inclined plate, the top edges of the vertical plate and the inclined plate are connected, and the bottom edges of the vertical plate and the inclined plate are in contact with the ground, forming a stable triangular support structure.

[0010] Preferably, in the vertical geogrid tensioning device with tension monitoring, the linkage mechanism includes a first link and a second link. The upper end of the first link is hinged to the swing arm, the lower end of the first link is hinged to the second link, the middle part of the second link is rotatably connected to the upright, and the lower end of the second link is connected to the tensioning seat.

[0011] Preferably, in the vertical geogrid tensioning device with tension monitoring, the swing arm is a bent arm.

[0012] Preferably, in the vertical geogrid tensioning device with tension monitoring, a spring force gauge is connected between the linkage mechanism and the triangular base.

[0013] Preferably, in the vertical geogrid tensioning device with tension monitoring, the tensioning base includes: a crossbar and several hooks, the hooks being mounted on the crossbar, and a mounting seat for hinged connection with the linkage mechanism being provided on the crossbar.

[0014] Preferably, in the vertical geogrid tensioning device with tension monitoring, the crossbar is directly connected to the triangular base by an elastic support.

[0015] Preferably, in the vertical geogrid tensioning device with tension monitoring, the crossbar is provided with a through hole, and the triangular base is provided with a sliding rod, one end of which moves through the elastic support and the through hole.

[0016] A construction method for the vertical geogrid tensioning device with tension monitoring, comprising:

[0017] The tensioning rod is used to hang a geogrid on the hook of the tensioning seat, and the triangular base is placed on the ground foundation.

[0018] Construction workers stand on the triangular base or footboard, hold the upright with one hand, and operate the swing arm with the other. By swinging the swing arm, the linkage mechanism is driven to swing, which in turn drives the tensioning seat to move towards the triangular base, thereby tensioning the geogrid.

[0019] After fixing the geogrid with pins, release the swing arm, and under the action of the elastic support, the tensioning seat will be reset. The hook will be detached from the geogrid, and the upright pole will be lifted and moved to the next geogrid for tensioning.

[0020] The present invention has at least the following beneficial effects:

[0021] First, the structure in the device of the present invention that applies force to the tensioning seat includes a triangular base, a vertical pole, a swing arm, and a linkage mechanism. The triangular base forms a stable triangular support structure with the ground. The vertical pole is set on the triangular base for the operator to hold. The swing arm and linkage mechanism are rotatably set on the vertical pole for the operator to operate. During tensioning construction, the worker steps on the triangular base or a footboard, holds the vertical pole with one hand, and pulls the swing arm with the other, thereby driving the linkage mechanism to tension the geogrid. Therefore, the tensioning force can be applied to the geogrid very quickly and stably, thus improving construction efficiency.

[0022] Secondly, the vertical geogrid tensioning device with tension monitoring of the present invention has a simple structure and does not have a motor or battery, so it is lightweight. Operators can carry the upright pole and move it quickly, making it flexible and convenient to perform full-width tensioning operations on each geogrid.

[0023] Third, the present invention is also equipped with a foot pedal, which is convenient for the operator to step on and improves stability. The triangular base and the bottom surface of the foot pedal are provided with nails, which effectively improves the grip on the ground and prevents slipping. It can effectively cope with different ground conditions.

[0024] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0025] Figure 1 This is a schematic diagram of the vertical geogrid tensioning device with tension monitoring described in this invention.

[0026] Figure 2 This is a schematic diagram of the tensioning seat body described in this invention. Detailed Implementation

[0027] The present invention will be further described in detail below with reference to examples, so that those skilled in the art can implement it based on the description.

[0028] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0029] like Figure 1 and Figure 2 As shown, a vertical geogrid tensioning device with tension monitoring includes:

[0030] 1. Upright pole, 2. Triangular base, 7. Swing arm, 8. Linkage mechanism, and 4. Tensioning seat;

[0031] The upright 1 is mounted on the triangular base 2. The swing arm 7 and the linkage mechanism 8 are rotatably connected to the upright 1. One end of the linkage mechanism 8 is connected to the swing arm 7, and the other end of the linkage mechanism 8 is connected to the tensioning seat 4. The tensioning seat 4 is used to hook with the geogrid 10. The swing arm 7 swings to drive the linkage mechanism 8 to swing, thereby driving the tensioning seat 4 to move and tension the geogrid 10.

[0032] For details, please refer to Figure 1 The upright 1 is fixed to the triangular base 2 by welding or bolting. The upright is easy for operators to hold and apply force to, and also easy to carry and move. The triangular base supports the ground, forming a stable support structure that facilitates tensioning operations. In the illustration, the swing arm 7 and the linkage mechanism 8 are connected and hinged to the upright 1 via a rotating shaft or hinge shaft, allowing it to swing. The swing arm is preferably a 7-shaped bent structure, an arc-shaped bent structure, or other bent structures, designed to drive the linkage structure to swing. Preferably, the linkage structure includes a first link and a second link. In the illustration, the upper end of the first link is hinged to the lower end of the swing arm, the lower end of the first link is hinged to the upper end of the second link, the middle part of the second link is connected or hinged to the upright via a rotating shaft or hinge shaft, and the lower end of the second link is hinged to the tensioning seat 4. When the swing arm swings, the first link drives the second link to swing, thereby driving the tensioning seat 4 to move. The tensioning seat 4 is equipped with hooks 5 for hooking the geogrid.

[0033] During operation, the worker holds the upright pole 1, hooking the tensioning seat 4 onto the geogrid 10. The triangular base 2 is placed on the ground, and the worker steps on the triangular base 2 to make it more stable. Then, holding the upright pole 1 with one hand and operating the swing arm 7 with the other, the worker drives the tensioning seat 4 to move and tension the geogrid 10 through the linkage mechanism 8. Then, the worker uses pins to fix the tensioned geogrid 10. After fixing, the worker moves the upright pole to the next geogrid for tensioning.

[0034] Furthermore, in another implementation, such as Figure 1 As shown, it also includes a pedal 3 connected to the triangular base 2. The pedal 3 facilitates the operator's footsteps and increases the contact with the ground.

[0035] Furthermore, in another implementation, such as Figure 1 As shown, the bottom of the triangular base 2 and the pedal 3 are provided with several protruding nails; preferably, the nails are located at the part of the triangular base or pedal that contacts the ground. In the illustration, the bottom of the triangular base 2 is provided with several first nails 201, and the bottom of the pedal 3 is provided with several second nails 301. The nails can be screws, bolts, or other protruding structures that can increase grip. The nails are preferably evenly spaced and the nails are welded or bolted to the triangular base or pedal.

[0036] Furthermore, in another implementation, such as Figure 1 As shown, the triangular base 2 includes a vertical plate and an inclined plate. The top edges of the vertical plate and the inclined plate are connected and fixed, and the bottom edges of the vertical plate and the inclined plate are in contact with the ground, forming a stable triangular support structure. This structure is very simple and lightweight, and can be fixed by welding two plates together, without the need for a base plate, making it easy to manufacture and durable. Preferably, the nails are provided along the bottom edges of the vertical plate and the inclined plate.

[0037] Furthermore, in another embodiment, the linkage mechanism 8 includes a first link and a second link. The upper end of the first link is hinged to the swing arm 7, and the lower end of the first link is hinged to the second link. The middle part or a position near the middle of the second link is rotatably connected to the upright, and the lower end of the second link is connected to the tensioning seat. In the illustration, the middle part of the second link is connected to the upright 1 via a hinge shaft, thereby enabling it to swing back and forth, thus driving the tensioning seat to move back and forth.

[0038] Furthermore, in another implementation, such as Figure 1 As shown, the swing arm is a bent arm. Preferably, it is a figure-7 shaped bent arm, but an arc-shaped arm can also be used, as long as it is convenient for the operator to operate and can drive the linkage mechanism to move.

[0039] Furthermore, in another implementation, such as Figure 1 As shown, both the upright and the swing arm are equipped with handles for easy gripping.

[0040] Furthermore, in another implementation, such as Figure 1 As shown, a spring balance 9 is connected between the linkage mechanism 8 and the triangular base 2. The spring balance can provide the operator with a rough tension reference, facilitating the monitoring of the tension.

[0041] Furthermore, in another implementation, such as Figure 1 and 2 As shown, the tensioning seat 4 includes a crossbar and several hooks 5. The hooks 5 are mounted on the crossbar, and a mounting seat 402 for hinged connection with the linkage mechanism is provided on the crossbar. In the illustration, the lower end of the linkage mechanism 8 is provided with a hinge groove 801, and a rotating shaft is provided on the mounting seat. The rotating shaft passes through the hinge groove 801, so that the lower end of the linkage mechanism is rotatably connected to the mounting seat. When the linkage mechanism 8 swings, the lower end of the linkage mechanism 8 drives the tensioning seat 4 to move back and forth.

[0042] Furthermore, in another implementation, such as Figure 1 As shown, the crossbar is directly connected to the triangular base 2 by an elastic support 6. The elastic support can be a spring, which can provide elastic support to tension and restore the seat body.

[0043] Furthermore, in another implementation, such as Figure 1 and 2As shown, the crossbar is provided with a through hole 401, and the triangular base 2 is provided with a sliding rod. One end of the sliding rod is fixed to the triangular base, and the other end moves through the interior of the elastic support 6 and the through hole 401, so that the tensioning seat 4 can move back and forth.

[0044] One implementation process of the present invention is as follows:

[0045] like Figure 1 As shown, the tensioning pole is used to hook the hook 5 of the tensioning seat 4 onto a geogrid 10. The triangular base 2 is placed on the ground. The construction worker steps on the triangular base 2 or the footboard 3, holds the pole 1 with one hand, and operates the swing arm 7 with the other. The swing arm swings, driving the linkage mechanism 8 to swing, which in turn moves the tensioning seat 4 towards the triangular base 2, thus tensioning the geogrid 10. Then, the geogrid is fixed with pins. After releasing the swing arm 7, the tensioning seat returns to its original position under the action of the elastic support 6, disengaging the hook from the geogrid. The worker then moves the pole to the next geogrid for tensioning. This tensioning device completes the tensioning of the entire geogrid with a single pull of the swing arm. Compared with traditional screw tensioning and electric tensioning, it is faster, more efficient, simple in structure, lightweight, and easy to transport and carry. It is very suitable for tensioning operations on construction sites. A geogrid about 1 meter wide can be tensioned with a single pull of the swing arm, greatly improving construction efficiency.

[0046] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for the present invention. Further modifications can be readily implemented by those skilled in the art.
