Technical Field
[0001] The utility model relates to the field of anti-floating anchor rods, in particular to an anti-floating anchor rod structure. Background Art
[0002] In recent years, due to the large-scale development of underground space, there are more and more buildings with basements and single-building basements, and the depth is gradually increasing. Due to the small number of upper floors, the deadweight of the structure is often not enough to resist the buoyancy generated by groundwater. Therefore, it is necessary to install anti-pullout piles or anti-floating anchors.
[0003] The anti-floating anchor in the related art usually includes an anchor pile, the top of which is fixedly connected to a support frame, the anchor pile is used to be cast and fixed to the base layer, and the support frame is used to be cast and fixed to the building, thereby achieving anti-floating support for the building.
[0004] However, after the anchor piles are cast and fixed to the base layer, the anchor piles and the base layer are only fixed together by the extrusion and friction of concrete, which makes the connection strength between the anchor piles and the base layer relatively weak, thereby affecting the tensile effect of the anchor piles, which needs to be improved. Utility Model Content
[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an anti-floating anchor rod structure, which has the effect of improving the connection strength between the anchor rod pile and the foundation layer, thereby improving the tensile effect of the anti-floating anchor rod.

After the anchor pile and the base layer are cast, concrete can flow through the casting holes and be cast as one with the concrete in the base layer.
[0007] In a preferred example, the utility model can be further configured as follows: there is an angle difference between the axis lines of two adjacent casting holes, and the plurality of casting holes are arranged in a staggered manner.
[0008] In a preferred example, the utility model can be further configured as follows: the side wall of the anchor pile is integrally formed and connected with a plurality of casting plates, and the plurality of casting plates are arranged at equal intervals along the height direction of the anchor pile.
[0009] In a preferred example, the utility model can be further configured as follows: each group of the casting plates is provided with a plurality of casting plates, and the plurality of casting plates are arranged at equal intervals along the circumferential direction of the anchor pile.
[0010] In a preferred example, the utility model can be further configured as follows: a plurality of grouting holes are respectively opened on each of the casting plates.
[0011] In a preferred example, the utility model can be further configured as follows: the casting plate and the anchor pile are connected via reinforcing ribs.
[0012] In a preferred example, the utility model can be further configured as follows: an inverted cone-shaped receiving seat is fixedly connected to the bottom of the anchor pile, and the diameter of the bottom surface of the receiving seat is greater than the diameter of the anchor pile.
[0013] In summary, the utility model has the following beneficial effects:
[0014] 1. By setting a casting hole on the anchor pile, after the anchor pile and the foundation are cast, the concrete enters the casting hole and forms an integrated structure with the concrete in the foundation, which can not only limit the anchor pile in the vertical direction, but also improve the strength of the connection structure between the anchor pile and the foundation, thereby improving the tensile strength of the anti-floating anchor;
[0015] 2. By setting a casting plate on the anchor pile, the connection stability between the anti-floating anchor and the foundation is further improved, thereby improving the tensile effect of the anti-floating anchor. BRIEF DESCRIPTION OF THE DRAWINGS
