Technical Field

[0001] The utility model provides a ground anchor device for building construction, and relates to the technical field of ground anchors. Background Art

[0002] At the construction site, anchoring devices are often needed to anchor some temporarily erected equipment to ensure their stable operation and ensure the safety of operations. Ground anchors can be divided into anchor piles, anchor points, anchor ingots, and drag pits. Ground anchors are often used in lifting operations to fix towing ropes, wind ropes, winches, guide pulleys, etc. Ground anchors are generally made of steel wire ropes, steel pipes, reinforced concrete prefabricated parts, round logs, etc. as embedded parts and buried underground.

[0003] In the prior art, in order to facilitate the burying of ground anchors underground, a spiral blade is usually set at the bottom end of the anchor rod, and then the ground anchor is inserted into the ground in a rotating form through professional equipment. Compared with hammering it into the ground by external force, it is more convenient and safer. However, during construction, since the ground anchors need to be rotated with the help of professional large-scale rotating equipment, they can only be operated one by one, and the installation process will be more dependent on external equipment. In addition, the existing anchor rods are mainly fixed by deep insertion into the ground, and the firmness between the upper smooth section of the anchor rod and the ground is poor. For this reason, we propose a construction ground anchor device. Utility Model Content

Specifically, the driving shaft 11 can be driven to rotate by the motor 12, and the driving shaft 11 can drive the connecting head 9 to rotate, and the connecting head 9 can drive the lower rod body 1 to rotate, and the spiral blade 2 can be used to drill into the ground downward to continuously bury the ground anchor, such as Figure 3 As shown, two layers of plug-in rings 10 are provided inside and outside, which is beneficial to improving the stability of the connection between the upper rod body 3 and the connector 9 and preventing dust from penetrating.

[0021] Furthermore, if Figure 2 , Figure 4As shown, a cavity 13 is provided on the inner side of the upper rod body 3 in the utility model, and a reinforcement member 14 is provided in the cavity 13. The reinforcement member 14 includes a limit rod 21 fixedly connected to the inner wall of the cavity 13, an insertion rod 18 slidably arranged on the outside of the limit rod 21, a fixing ring 20 sleeved on the outside of the insertion rod 18 and fixedly connected to the inner side of the cavity 13, a rotating sleeve 22 rotatably arranged on the outside of the fixing ring 20, and a gear 19 fixedly connected to the end of the rotating sleeve 22. A threaded hole is provided at the center of the gear 19, the insertion rod 18 passes through the threaded hole, and an external thread matching the threaded hole is provided on the outer wall of the insertion rod 18, a through hole 8 matching the insertion rod 18 is provided on the side wall of the upper rod body 3, a tip is provided at the front end of the insertion rod 18, and a guide seat 17 slidably connected to the insertion rod 18 is fixedly connected to the inner wall of the cavity 13. Specifically, the cross-section of the limiting rod 21 is rectangular or cross-shaped, and is used to limit the insertion rod 18 so that the insertion rod 18 cannot rotate and can only move axially along the limiting rod 21. When the gear 19 rotates, the threaded hole cooperates with the external external thread of the insertion rod 18 to form a threaded transmission, which can drive the insertion rod 18 to move axially along the limiting rod 21, extend out of the through hole 8, and be inserted into the external soil to reinforce the upper rod body 3.

[0022] Furthermore, if Figure 2 As shown, the top of the upper rod body 3 in the utility model is fixedly connected with an end cover 4, the inner side of the end cover 4 is fixedly connected with a threaded sleeve 15, the inner thread of the threaded sleeve 15 is connected with a screw rod 6, one end of the screw rod 6 is connected with a ring 5, and the other end is rotatably connected with a rack rod 16 meshing with a gear 19, and the inner side of the rack rod 16 is slidably connected with a rectangular rod 23. Specifically, a round shaft is provided at the bottom end of the rack rod 16, and a mounting hole matching the round shaft is opened at the bottom end of the screw rod 6. The round shaft is rotatably connected in the mounting hole through a bearing. The width of the rack rod 16 is smaller than the inner diameter of the threaded sleeve 15, that is, the rack rod 16 can move up and down freely in the threaded sleeve 15 without any movement obstruction with the inner wall of the threaded sleeve 15. The rectangular rod 23 guides the rack rod 16, so that the rack rod 16 cannot rotate and can only move up and down. When the lifting ring 5 is rotated and the screw rod 6 is screwed downward into the threaded sleeve 15, the screw rod 6 pushes the rack rod 16 to move downward, so that the rack rod 16 drives the gear 19 to rotate.

Specifically, Figure 2 As shown, at least four reinforcement members 14 are provided to ensure the reinforcement effect of the upper rod body 3 .

[0024] Furthermore, if Figure 1As shown, the bottom edge of the end cover 4 in the present invention is fixed with a ground nail 7, and the ground nail 7 is evenly arranged around the circumference of the end cover 4. When the ground anchor is buried underground, the end cover 4 fits the ground, and the ground nail 7 is inserted into the ground, and the ground nail 7 further improves the overall stability of the ground anchor.

[0025] Furthermore, in the utility model, a socket is also provided at the top of the end cover 4, a dust cover is provided on the outside of the socket, a wire is connected between the socket and the motor 12, and the wire is embedded in the inner wall of the upper rod body 3. The motor 12 can be connected to an external power supply through the wire and the socket, and the electrical connection method of the motor can adopt the existing wiring structure, which is a prior art known to those skilled in the art, so it will not be described in detail.

[0026] Working principle: Start the motor 12 to drive the lower rod body 1 to rotate, and drive the anchor to drill into the ground continuously through the spiral blade 2. After the anchor is completely underground, rotate the lifting ring 5 to screw the screw 6 downward into the threaded sleeve 15. The screw 6 pushes the rack rod 16 to move downward, and the rack rod 16 drives the gear 19 to rotate. The gear 19 drives the insertion rod 18 to extend out of the upper rod body 3 and insert it into the surrounding soil to reinforce the upper rod body 3.

[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
