[0036] The present utility model will be further described below with reference to the accompanying drawings in specific embodiments. See Figures 1-5 :

[0037] Embodiment 1:

[0038] This embodiment provides an assembled pier cap anchoring structure, including:

[0039] A square frame 1, with at least four square frames 1 arranged in sequence along the Z direction;

[0040] A plurality of vertical plates 2, vertically arranged and placed in sequence along the Y direction. The two sides of the vertical plate 2 in the X direction are fixed to the inner circumference of the square frame 1, and a plurality of through holes are provided on the vertical plate 2 along the Y direction;

[0041] A plurality of fixing members 3, arranged between two adjacent vertical plates 2, and both ends of the fixing member 3 are fixed to the lowermost square frame 1;

[0042] Among them, a plurality of fixing holes 32 are provided through the fixing member 3 along the Z direction, and an anchoring prestressed tendon 31 is arranged in the fixing hole 32. One end of the anchoring prestressed tendon 31 is embedded in the underlying foundation, and the other end of the anchoring prestressed tendon 31 is connected to the fixing member 3.

[0043] As Figures 1-4 shown, the vertical plate 2 is fixedly welded to the square frame 1, and a plurality of through holes for inserting fixing materials are provided on the vertical plate 2 to enhance the overall stability of the anchoring structure.

[0044] Both sides of the fixing member 3 are provided with grooves. The fixing member 3 is arranged on the square frame 1 at the bottommost part. After the square frame 1 is clamped with the grooves on the fixing member 3, it is welded and fixed. The fixing member 3 is provided with a fixing hole 32, and an anchoring prestressed tendon 31 is arranged in the fixing hole 32. During construction, one end of the anchoring prestressed tendon 31 is first embedded in the foundation ground, and the other end is inserted into the fixing hole 32 and fixed to the fixing member 3. Then, a jack is used to stretch the anchoring prestressed tendon 31 to provide prestress, and the pier cap anchoring structure is integrally fixed in the cap, so that it will not move laterally, increasing the stability of the overall structure and ensuring the accuracy of the insertion of fixing materials such as steel bars in the later construction.

[0045] The vertical plate 2, the fixing member 3, and the square frame 1 can be made of metal materials such as aluminum alloy. The present utility model is preferably made of steel, which has high strength, good wear resistance and corrosion resistance, and certain seismic resistance, and can improve the bearing capacity and durability of the anchoring structure.

[0046] In this embodiment, after the pier cap anchoring structure is installed, it is embedded into the cap, and anchoring materials such as steel bars are inserted to improve the overall load-bearing strength of the bridge. While fixing the steel bars, the pier cap anchoring structure itself also has a certain fixing and bearing capacity, which can improve the overall strength of the cap and increase the stability and durability of the bridge.

[0047] In this embodiment, the pier cap anchoring structure can assemble and fix the vertical plate 2, the square frame 1, and the fixing member 3 according to the actual situation, and adjust the number of the vertical plate 2, the square frame 1, and the fixing member 3 according to the actual needs, so as to adapt to caps of different scales and enhance the flexibility of use.

The connecting plate 4 can make the connection between the square frame 1 and the vertical plate 2 more stable, prevent the fixing structure between the vertical plate 2 and the square frame 1 from loosening due to excessive pressure, enhance the overall stability of the anchoring structure, and increase the bearing capacity of the anchoring structure.

[0051] Embodiment 2:

[0052] This embodiment provides an assembled pier cap anchoring structure, which has the following technical features in addition to the technical solutions of the above embodiment.

[0053] The through holes include:

[0054] The first steel bar reserved holes 21, there are multiple first steel bar reserved holes 21, and the first steel bar reserved holes 21 are evenly arranged along the X direction.

[0055] There are two rows of the first steel bar reserved holes 21 along the X direction, which are arranged at the upper and lower parts of the vertical plate 2. The first steel bar reserved holes 21 are used for the steel bars to pass through the vertical plate 2 along the Y direction, which can enhance the overall compressive, tensile and shear resistance of the anchoring structure. When the overall structure is subjected to external forces, the transverse steel bars can evenly distribute the external forces to the entire structure, thereby effectively improving the overall compressive and tensile resistance of the bearing platform. The setting of the transverse steel bars makes the bearing platform more stable and safe when subjected to external forces, reducing the possibility of structural deformation and damage caused by external forces.

[0056] At the same time, it can also prevent the longitudinal steel bars from sliding under the action of external loads. In a concrete structure, the deformation of the longitudinal steel bars caused by the action of loads may cause the loss of the anchoring capacity of the anchoring structure, thereby affecting the strength and stability of the bearing platform. The transverse steel bars fix the longitudinal steel bars, avoiding their sliding under the action of external forces, thus ensuring the stability and safety of the concrete structure.

[0057] The through holes further include:

[0058] The strand reserved holes 22, there are multiple strand reserved holes 22, and the strand reserved holes 22 are evenly arranged along the X direction.

[0059] The strand reserved holes 22 are arranged in two rows between the two rows of the first steel bar reserved holes 21. The strand reserved holes 22 can be used for inserting strands. After inserting the strands, the overall structure can be strengthened, and the bearing capacity and safety factor of the bearing platform can be improved. At the same time, the strands can optimize the anchoring structure, making the anchoring structure more simplified, and saving the use of steel bars and reducing the construction cost.

[0060] The through holes further include:

[0061] The tie rod anchoring reserved holes 23, there are multiple tie rod anchoring reserved holes 23, and the tie rod anchoring reserved holes 23 are evenly arranged along the X direction. The tie rod anchoring reserved holes 23 are arranged above the fixing member 3.

[0062] The tie rod anchoring reserved holes 23 are arranged in two rows below the strand reserved holes 22. The anchoring tie rods can be inserted into the tie rod anchoring reserved holes 23 to tightly connect the bearing platform with the anchoring structure, which can effectively enhance the overall stability of the structure. And the anchoring tie rods can bear the loads from above the bearing platform and effectively transfer them to the foundation. This load transfer effect helps to ensure the structural integrity and durability of the building.

[0063] Example 3:

[0064] This embodiment provides an assembled pier cap anchoring structure. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0065] Bolts 11 for connecting with the square frame are provided on both sides of the vertical plate 2 in the x direction.

[0066] A number of threaded holes are provided on both sides of the vertical plate 2 and the square frame 1 in the X direction. Bolts 11 are provided in the threaded holes, and the vertical plate 2 and the square frame 1 are fixed by the bolts 11.

[0067] The vertical plate 2 and the square frame 1 are fixed by two methods of bolts 11 and welding, making the overall pier cap anchoring structure more firm and enhancing its durability and stability.

[0068] Second steel bar reserved holes 41 for inserting vertical steel bars are provided on both the fixing member 3 and the connecting plate 4.

[0069] Third steel bar reserved holes 12 for inserting vertical steel bars are provided on the square frame 1.

[0070] The insertion of the vertical steel bars increases the quantity and density of the internal steel bars of the pier, thereby improving the load-bearing capacity of the pier. And the vertical steel bars can effectively disperse and bear the loads from the upper structure of the bridge, ensuring the stability and safety of the pier under various working conditions.

[0071] At the same time, as the service life of the bridge increases, problems such as fatigue and aging may occur in the pier structure, resulting in a reduction in the stability of the bridge. The vertical steel bars of the pier cap can enhance the stability and durability of the pier structure. It can effectively limit the deformation and displacement of the pier, ensuring the stability and safety of the bridge during long-term use.

[0072] The second steel bar reserved holes 41 and the third steel bar reserved holes 12 are arranged in a staggered manner with the first steel bar reserved holes 21, the steel strand reserved holes 22, and the tie rod anchoring reserved holes 23, that is, the laterally inserted anchoring materials and the longitudinally inserted anchoring materials are arranged in a staggered manner. They do not conflict with each other when inserted and can be mutually clamped and fixed, enhancing the overall stability of the anchoring structure.

[0073] Example 4:

[0074] This embodiment provides an assembled pier cap anchoring structure. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0075] The fixing member 3 is in an I shape, and a number of stiffening ribs 33 are provided on both sides of the fixing member 3 along the X direction.

[0076] Since the prestress and pressure on the fixing member 3 are relatively large, the stiffening rib 33 effectively increases the flexural and torsional stiffness and load-bearing capacity of the fixing member 3, preventing deformation and damage when subjected to shear and bending loads, and making the overall anchoring structure more stable and safe.

[0077] The square frame 1 includes:

[0078] Connecting ribs 13, there are multiple connecting ribs 13, and the connecting ribs 13 are fixed at the four corners of the square frame 1.

[0079] The connecting ribs 13 are welded to the four corners of the square frame 1 to form a triangular structure, stabilizing the shape of the square frame 1 so that it is not easily deformed under external pressure, and improving the overall stability of the anchoring structure.

[0080] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
