[0003] The traditional anti-floating anchor head device of fine-rolled threaded steel bar usually sets a nut with a nut at the end of the steel bar for anchoring connection, but the contact area between the nut and the structure is small and cannot effectively transfer more loads.

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0028] like Figure 1 , Figure 2 As shown, a precision-rolled threaded steel anti-floating anchor structure comprises an anchor rod body 1 and an anchor joint 2. The anchor joint 2 is located at the upper end of the anchor rod body 1 and comprises a positioning nut 21, an anchor head steel plate 22 and an anchor nut 23.
[0029] like Figure 1 , Figure 2 As shown, the positioning nut 21 is threadedly connected to the anchor rod body 1, mainly controlling the position of the anchor head steel plate 22, and can control the installation height of the anchor head steel plate 22 in the base plate, thereby improving the shear resistance of the base plate concrete below the anchor head steel plate 22.
[0030] like Figure 1 , Figure 2 As shown, the anchor head steel plate 22 is sleeved on the anchor rod body 1 and is located above the positioning nut 21, and mainly plays the role of bearing the buoyancy of the groundwater on the bottom plate transmitted from the bottom plate in the vertical direction.
[0031] like Figure 1 , Figure 2 As shown, the anchor nut 23 is threadedly connected to the anchor rod body 1 and is used to compress the anchor head steel plate 22. The anchor nut 23 mainly fixes the anchor head steel plate 22 and the anchor rod body 1 and transmits the force borne by the anchor head steel plate 22 to the anchor rod body 1. Its specifications correspond to those of the anchor rod body 1, and the specifications and dimensions of the anchor head steel plate 22 and the specifications and quantity of the anchor nut 23 can be adjusted according to the design bearing capacity characteristic value.
[0032] After the grouting and curing of the anti-floating anchor is completed, the positioning nut 21 is installed on the anchor rod body 1 according to the design requirements, and then the anchor head steel plate 22 is passed through the anchor rod body 1 and placed on the positioning nut 21, and finally the anchor nut 23 is passed through the anchor rod body 1 until the anchor head steel plate 22 is firmly fixed.
[0033] Therefore, during the construction process, the size of the anchor head steel plate 22 and the number of anchor nuts 23 can be adjusted according to the maximum bearing capacity of the anti-floating anchor rod to ensure the construction effect. At the same time, placing the positioning nut 21 under the anchor head steel plate 22 can control the installation height of the anchor head steel plate 22 in the base plate, thereby improving the shear resistance of the base plate concrete under the anchor head steel plate 22.
[0034] At the same time, the anchor joint 2 has a simple structure and is easy to process. The materials used are all finished materials processed in the factory. They can be processed in large quantities in the factory and then transported to the construction site, reducing on-site processing and production, making procurement convenient and installation quick, which can significantly improve on-site construction efficiency.
[0035] like Figure 1 , Figure 3 As shown, a plurality of bearing members 3 are arranged at intervals at the lower end of the anchor rod body 1. The bearing member 3 comprises a sleeve 31 and a bearing plate 32. The sleeve 31 is threadedly connected to the anchor rod body 1, and the bearing plate 32 is arranged at the upper end of the sleeve 31.
[0036] like Figure 1 , Figure 3 As shown, a circle of notches 33 are arranged at intervals at the outer edge of the bearing plate 32, and a stiffening plate 34 is arranged between the outer wall of the sleeve 31 and the lower end surface of the bearing plate 32. The stiffening plate 34 is located between two adjacent notches 33, and the bending position of the stiffening plate 34 is arranged in a circular arc transition shape.
[0037] By arranging the bearing member 3, anti-floating nodes can be formed at various positions of the anchor rod body 1, thereby increasing the overall structural strength and anti-floating ability of the anchor rod body 1, ensuring the stability of the base structure, and at the same time improving the shearing resistance of the entire anti-floating anchor rod to the bottom, thereby ensuring the structural strength and stability of the anti-floating anchor rod.
[0038] like Figure 1 , Figure 4 As shown, the lower end of the anchor rod body 1 is provided with an anti-floating member 4 capable of expanding outwards, and the anti-floating member 4 includes a tube body 41 , a plate body 42 and a driving mechanism 43 .
[0039] like Figure 1 , Figure 4 As shown, the tube body 41 is threadedly connected to the lower end of the anchor rod body 1, the upper end of the plate body 42 is rotatably connected to the lower end of the tube body 41, and the driving mechanism 43 is used to control the lower end of the plate body 42 to flip outward.
[0040] like Figure 1 , Figure 4 As shown, the driving mechanism 43 includes a driving rod 44, a driving tube 45 and a push rod 46. The driving rod 44 is vertically arranged in the tube body 41, and the driving tube 45 is vertically slidably connected to the driving rod 44, and the lower end is lower than the lower end of the plate body 42. One end of the push rod 46 is rotatably connected to the outer wall of the driving tube 45, and the other end is tilted upward and rotatably connected to the lower inner wall of the plate body 42.
[0041] When installing the anti-floating anchor rod, as the anchor rod body 1 gradually extends downward, the driving tube 45 will contact the bottom wall of the ground drill hole, and during the continuous descent of the anchor rod body 1, the driving tube 45 will slide upward and control the push rod 46 to move synchronously. At this time, the push rod 46 drives the lower end of the plate body 42 to automatically flip outward, thereby realizing the automatic opening of the anti-floating component 4.
[0042] Therefore, after pouring, the outwardly expanded plate body 42 can form an anti-floating node in the opposite direction at the bottom position of the anchor rod body 1 to resist the buoyancy and surge force of groundwater, increase the overall structural strength and anti-floating ability of the anchor rod body 1, and ensure the stability of the base structure.
[0043] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
