[0002] A pre-embedded foot bolt anchor is a connector pre-buried in a concrete structure. It is usually composed of a screw, nut, gasket and other accessories. One end of the anchor is embedded in the concrete, and the other end is exposed on the concrete surface. It is used to connect and fix other structural components, such as steel columns, equipment brackets, etc.

[0003] During the construction of embedded parts, finished anchor parts of fixed size have certain limitations during the construction process. The anchor parts made on site need to spend a certain amount of time and energy to make them when used, and the embedded depth cannot be flexibly adjusted to adapt to different installation requirements. In addition, the integrity between the anchor parts is poor when a single embedded anchor part is used, which may cause the embedded parts to become loose or shifted during subsequent use, affecting the stability and safety of the overall structure. For this reason, it is necessary to provide a concrete embedded foot bolt anchor and ground fixing structure, which adopts the characteristics of adjustable embedded depth and mutual restraint between anchor parts through embedded plates, so as to improve the stability and supporting performance of the overall support base point, reduce the later maintenance costs and safety hazards caused by loose fixation, and improve the overall quality and efficiency of the project.

[0022] Hereinafter, embodiments of the embedded part foot bolt anchor and ground fixing structure of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4The utility model shows an embedded foot bolt anchor and ground fixing structure of an embodiment of the present invention, including a concrete platform 1: an embedded plate 2 is provided on the top of the concrete platform 1, and steel guard plates 4 are attached to the four sides of the concrete platform 1. Two L-shaped embedded rods 5 are welded to the side of the steel guard plate 4 close to the concrete platform 1, and the L-shaped embedded rods 5 are implanted into the interior of the concrete platform 1. Through the coordinated use of the steel guard plate 4 and the L-shaped embedded rods 5, the surface of the concrete platform 1 is wrapped and protected, thereby improving the overall stability of the concrete platform 1 and enhancing the supporting stability of the subsequent docking structure with the embedded plate 2 or the docking screw 31. Bolt anchor assemblies 3 are provided at the four corners of the top of the embedded plate 2. The bolt anchor assembly 3 includes a docking screw 31 that is penetrated from the top of the embedded plate 2 to the inner wall of the concrete platform 1. Two third nuts 8 are threadedly connected to the top of the surface of the docking screw 31. The surface of the docking screw 31 is provided with an anti-slip gasket 9. The anti-slip gasket 9 is squeezed on the top of the embedded plate 2 by the third nut 8. The surface of the threaded sleeve 33 is annularly provided with a plurality of immersion Hole 10, embedded screw 32 is provided below the docking screw 31, and support frames 6 are provided on the front and rear sides of the bottom of the embedded plate 2. The top of the support frame 6 is provided with an arc-shaped through hole 7 adapted to the docking screw 31 and the embedded screw 32. The two ends of the support frame 6 are respectively placed on the top of the two steel guard plates 4. The top of the support frame 6 is tightly fitted with the bottom of the embedded plate 2. The setting of the support frame 6 supports the embedded plate 2, so that the bottom of the embedded plate 2 can contact with the concrete platform 1, thereby making The concrete platform 1 has a good supporting effect on the steel guard plate 4 after solidification. The opposite ends of the docking screw 31 and the embedded screw 32 are threadedly connected with a threaded sleeve 33, and the bottom of the surface of the embedded screw 32 is provided with an anti-slip embedded plate 34. The top and bottom of the anti-slip embedded plate 34 are provided with a first nut 35 threadedly connected to the embedded screw 32, and the top and bottom of the threaded sleeve 33 are provided with a second nut 36. The two second nuts 36 are respectively threadedly connected to the surfaces of the docking screw 31 and the embedded screw 32.

[0024] Working principle: When using the present invention, the user first encloses the steel guard plate 4 to form a rectangular cavity, and then places the support frame 6 on the top of the steel guard plate 4. Then, the embedded depth is adjusted. When adjusting, the user rotates the threaded sleeve 33 to adjust the spacing between the docking screw 31 and the embedded screw 32. After the adjustment is completed, the user rotates the two second nuts 36 to clamp the position of the threaded sleeve 33 to prevent the docking screw 31, the embedded screw 32 and the threaded sleeve 33 from rotating on their own. Then, the user passes the docking screw 31 through the top of the embedded plate 2 and makes the bottom of the embedded plate 2 contact with the top of the support frame 6. The docking screw 31, the embedded screw 32, the threaded sleeve 33 and the anti-slip embedded plate 34 are all located in the cavity formed by the four steel guard plates 4. Then the user pours concrete into the cavity, and the fluid concrete enters the inner cavity of the threaded sleeve 33 from the immersion hole 10, and contacts the docking screw 31 and the embedded screw 32. After the concrete is completely solidified, the anti-slip embedded plate 34, the embedded screw 32, the docking screw 31 and the threaded sleeve 33 are all fixed, and the support frame 6 and the embedded plate 2 are also fixed. Finally, the user screws the third nut 8 so that the anti-slip gasket 9 is tightly pressed on the top of the embedded plate 2. The subsequent installation structure can be welded to the top of the embedded plate 2 or threadedly connected to the docking screw 31.

[0025] To sum up: the embedded foot bolt anchor and the ground fixing structure, through the cooperation of the concrete platform 1 and the steel guard plate 4, provide a stable installation platform for the embedded plate 2. At the same time, through the setting of the bolt anchor assembly 3, the embedded plate 2 is threadedly fixed, so that the embedded plate 2 can be fixed by the thread squeeze at the same time, and can also be fixed by the concrete platform 1 after solidification, so as to achieve the purpose of adjustable embedded depth and high installation strength.
