[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Embodiment: Please refer to Figs. 1 to 4 A steel column pile foundation structure, comprising a pile hole 1, a concrete pile foundation 2 located at the bottom of the pile hole 1 and a steel column body 3 embedded in the concrete pile foundation 2, the upper end of the steel column body 3 extends out of the pile hole 1, which can provide stable supporting force to ensure the stability and safety of the building.

[0026] The embodiment also comprises an annular inner steel plate 4, an annular outer steel plate 5, a plurality of shear plates 6 and a plurality of pouring holes 7.

[0027] In the embodiment, the annular inner steel plate 4 is fixed to the lower end of the steel column body 3 near the end portion, and the annular inner steel plate 4 is located above the concrete pile foundation 2, which does not affect the insertion of the steel column body 3 into the concrete pile foundation 2.

[0028] Specifically, the annular outer steel plate 5 is located at the periphery of the annular inner steel plate 4 and is attached to the pile hole 1. The plurality of shear plates 6 are fixed between the annular inner steel plate 4 and the annular outer steel plate 5 along the circumference of the annular inner steel plate 4 at equal intervals. When the steel column body 3 is inserted into the concrete pile foundation 2, the cooperation of the annular inner steel plate 4, the annular outer steel plate 5 and the plurality of shear plates 6 can prevent the steel column body 3 from tilting or deviating.

[0029] It should be noted that the plurality of pouring holes 7 are provided on the steel column body 3 along the circumference of the steel column body 3 at equal intervals, and each pouring hole 7 is located in the inner periphery of the annular inner steel plate 4, and the upper and lower ends of each pouring hole 7 extend out of the annular inner steel plate 4. After the steel column body 3 is inserted into the concrete pile foundation 2, concrete is poured into the steel column body 3, and part of the concrete will enter the gap between the steel column body 3 and the pile hole 1 through the pouring hole 7, thereby filling the gap between the steel column body 3 and the pile hole 1, so that the steel column body 3 will not tilt or deviate, improving the stability.

[0030] In the embodiment, the pouring hole 7 is long strip-shaped and arranged along the axial direction of the steel column body 3, which facilitates the concrete to enter the gap between the steel column body 3 and the pile hole 1. The annular inner steel plate 4 and the annular outer steel plate 5 are both arranged at intervals along the length direction of the pouring hole 7, which can provide stable support for the steel column body 3.

[0031] Preferably, the shear plates 6 are staggered with the pouring holes 7, which can ensure the shear capacity of the steel column body 3. Meanwhile, the existence of the shear plates 6 does not easily affect the concrete to enter the gap between the steel column body 3 and the pile hole 1 through the pouring hole 7.

[0032] It is worth mentioning that the reinforcing bars 8 are fixedly connected between the two adjacent shear plates 6 above and below, and each reinforcing bar 8 is arranged along the axial direction of the steel column body 3. Through the cooperation of the shear plates 6 and the reinforcing bars 8, the shear capacity of the steel column body 3 can be ensured, and the uplift capacity of the steel column body 3 can be improved.

[0033] Since the pouring hole 7 is arranged on the steel column body 3, in order to further ensure the shear capacity of the steel column body 3, the following design is made:

[0034] The steel column body 3 is arranged with a fixed rod 9 inside along the axial line and located inside the pouring hole 7. A plurality of connecting pieces 10 are fixedly arranged at intervals along the axial direction of the fixed rod 9, and the end of each connecting piece 10 away from the fixed rod 9 is fixed to the inner side of the steel column body 3. Specifically, the connecting piece 10 comprises a plurality of shear rods fixedly arranged at intervals along the circumferential direction of the fixed rod 9 between the steel column body 3 and the fixed rod 9. The shear rods are staggered with the pouring holes 7, which can further ensure the shear capacity of the steel column body 3 and make the overall structure of the steel column body 3 more stable.

[0035] The working principle is as follows:

[0036] The lower end of the steel column body 3 is inserted into the poured concrete pile foundation 2. During the insertion process, the cooperation of the annular inner steel plate 4, the annular outer steel plate 5 and the shear plate 6 can prevent the steel column body 3 from tilting or deviating in the pile hole 1. After the steel column body 3 is inserted into place, the concrete is poured into the steel column body 3, and the concrete enters the gap between the steel column body 3 and the pile hole 1 through the pouring hole 7. After the concrete is filled, the concrete is allowed to solidify, which can ensure the shear capacity and the uplift capacity of the steel column body 3 under the action of the concrete, the shear plate 6, the reinforcing bar 8 and the connecting piece 10.
