Description

Technical Field

[0001] The utility model relates to the field of building facilities, in particular to an anchor pile structure for an underground garage. Background Art

[0002] Anchor piles are a form of anti-buoyancy measure for underground structures in construction projects. They are designed to resist the upward displacement of buildings above them, and their effects are related to the level and fluctuations of the groundwater level. As surface water seeps into the soil, the accumulation of water within it increases its internal buoyancy, causing underground garages within the soil to float upward to a certain extent. To reinforce underground garages, anchor piles are often used to mitigate this buoyancy.

[0003] Anchor piles in related art typically include a supporting steel bar and multiple reinforcing steel bars. The multiple reinforcing steel bars surround the supporting steel bars and are welded to the supporting steel bars. However, when welding the supporting and reinforcing steel bars, it is difficult to ensure a constant spacing between adjacent reinforcing steel bars. If the spacing between adjacent reinforcing steel bars is uneven, it may affect the structural strength of the anchor pile and, in turn, the stability of the anchor pile. This requires improvement. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the utility model is to provide an underground garage anchor pile structure, which can ensure a constant distance between two adjacent reinforcing steel bars, ensure the structural stability of the anchor pile, and thus improve the stability of the anchor pile in use.

[0006] Each group of support rings is provided with multiple support rings, and the multiple support rings are arranged at equal intervals in the vertical direction. The side walls of each support ring are provided with multiple positioning notches, and the reinforcing steel bars can be tightly inserted into the corresponding positioning notches and welded to the support rings.

[0007] In a preferred example, the present invention can be further configured as follows: a support seat is welded and fixed to the bottom of the support steel bar, a plurality of positioning grooves are provided on the upper surface of the support seat, and the bottom ends of the plurality of reinforcing steel bars are respectively inserted into the corresponding positioning grooves and respectively welded and fixed to the support seat.

[0008] In a preferred example, the present invention can be further configured as follows: a plurality of expansion clips are fixedly connected to the edge of the bottom of the support seat, and an extrusion piece is provided at the bottom of the support seat, which can make the bottom ends of the plurality of expansion clips expand outward respectively.

[0010] In a preferred example, the present invention can be further configured as follows: the bottom of each expansion card is fixedly connected to a limiting nail, and the limiting nail can be nailed into the stratum.

[0011] In a preferred example, the present invention can be further configured as follows: a plurality of grouting holes are respectively provided on each of the support rings, and the plurality of grouting holes are arranged at equal intervals along the circumference of the corresponding support ring.

[0018] The present invention will be described in further detail below with reference to the accompanying drawings.

[0019] Reference Figure 1 、 Figure 2 An anchor pile structure for an underground garage includes a supporting steel bar 1 and a plurality of reinforcing steel bars 2. The anchor pile structure also includes three groups of support rings 3. The three groups of support rings 3 are distributed at the upper, middle and lower positions of the supporting steel bar 1. The three groups of support rings 3 are respectively sleeved on the supporting steel bar 1 and are respectively welded and fixed to the supporting steel bar 1.

[0020] Reference Figure 1 、 Figure 2 Each group of support rings 3 is provided with multiple support rings 3, and the multiple support rings 3 are arranged at equal intervals along the vertical direction. At the same time, the side wall of each support ring 3 is provided with multiple positioning notches 4, and the reinforcing steel bars 2 can be tightly inserted into the corresponding positioning notches 4 and welded to the support rings 3.

[0021] When the anchor pile structure needs to be welded and fixed, multiple reinforcing bars 2 are respectively inserted into corresponding positioning notches 4, thereby defining the welding positions of the reinforcing bars 2 and ensuring a constant spacing between adjacent reinforcing bars 2. Subsequently, the reinforcing bars 2 can be welded. This design ensures the spacing between adjacent reinforcing bars 2, thereby ensuring the structural stability of the anchor pile. It also facilitates the construction workers to quickly weld the anchor pile, improving construction efficiency.

[0022] Reference Figure 1 、 Figure 2 A support seat 5 is welded and fixed to the bottom of the supporting steel bar 1, and a plurality of positioning grooves 6 are provided on the upper surface of the supporting seat 5. The bottom ends of the plurality of reinforcing steel bars 2 are respectively inserted into the corresponding positioning grooves 6 and welded and fixed to the support seat 5 respectively. This design can not only improve the positioning effect of the reinforcing steel bars 2, but also improve the structural strength of the anchor pile.

[0023] Reference Figure 1 、 Figure 2 A plurality of expansion plates 7 are fixedly connected to the edge of the bottom of the support seat 5, and an extrusion member 8 is provided at the bottom of the support seat 5. The extrusion member 8 can make the bottom ends of the plurality of expansion plates 7 expand outward respectively, and make the expansion plates 7 tightly abut against the formation, so as to improve the connection stability between the anchor pile and the formation.

[0024] Reference Figure 1 、 Figure 2 The extrusion member 8 includes an extrusion plate 81 mounted at the bottom of the support base 5. The extrusion plate 81 is connected to the support base 5 via a telescopic rod 82. An extrusion slope 83 is provided at the top edge of the extrusion plate 81. When the construction workers drive the anchor pile into the pile hole, the extrusion plate 81 moves upward under the influence of the pile hole bottom wall. At this time, the expansion plate 7 can expand outward under the influence of the extrusion slope 83.

[0025] Reference Figure 1 、 Figure 2The bottom of each expansion card plate 7 is fixedly connected with a limit nail 9, and the limit nail 9 can be nailed into the formation to improve the connection stability between the expansion card plate 7 and the formation, thereby improving the connection structure strength between the anchor pile and the formation.
