[0006] Height-adjusting nuts and washers are provided between the base steel plate and the embedded steel plate.

[0007] The base steel plate and the embedded steel plate are sealed by filling concrete.

[0008] The steel bars penetrate the base steel plate and are fixed to prevent loosening by double nuts and washers.

[0009] The base steel plate is provided with holes matching the positions of the steel bars, and the holes are grooved in a direction perpendicular to the line.

[0010] The foundation steel plate is provided with connecting steel bars, the interior of the precast concrete column is provided with structural steel bars, and the connecting steel bars and the structural steel bars are welded to form a whole.

[0016] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by technicians in the same industry:

[0017] like Figure 1-3 As shown in the figure, marks 1-10 respectively represent: precast concrete column 1, double nut and washer 2, foundation steel plate 3, height adjustment nut and washer 4, embedded steel plate 5, steel bar 6, concrete 7, hole 8, slot 9, threaded section 10.

[0018] Example: Figures 1 to 3 As shown, the prefabricated track columns for the parking lot in this embodiment are used to install prefabricated concrete columns 1 for supporting rails on the civil construction floor.

[0019] Specifically, the bottom of the precast concrete column 1 in this embodiment is provided with a foundation steel plate 3, and the two are prefabricated simultaneously to form an integral structure. Specifically, connecting steel bars arranged in a plum blossom shape are welded on the foundation steel plate 3, and then the structural steel bars of the precast concrete column 1 are tied, and the connecting steel bars and the structural steel bars are welded to form an integral structure, and then concrete is poured by formwork casting to form the precast concrete column 1.

[0020] In this embodiment, if Figure 2 As shown, a hole 8 for connecting with the embedded parts in the underlying civil engineering floor is provided on the foundation steel plate 3, and a groove 9 is provided in the vertical line direction on the hole 8.

[0021] Combination Figure 1 and Figure 3 As shown, a pre-buried steel plate 5 and a steel bar 6 are pre-buried in the civil engineering floor. The pre-buried steel plate 5 and the steel bar 6 are welded and fixed. The bottom of the steel bar 6 is bent and arranged inside the civil engineering floor to increase the connection performance between the two. The top of the steel bar 6 extends above the civil engineering floor and can pass through the hole 8 opened on the foundation steel plate 3. Figure 3 As shown, the top protruding end of the steel bar 6 is a threaded section 10. After the steel bar 6 passes through the hole 8, it can be fixed to prevent loosening by a double nut and a washer 2 matching the threaded section 10, so that the embedded steel plate 5 and the foundation steel plate 3 are fixedly connected to form a whole, thereby realizing the fixation of the precast concrete column 1.

[0022] In this embodiment, since the hole 8 has a slot 9 in the vertical line direction, when the precast concrete column 1 is installed and positioned, the slot 9 can be used to adjust the spacing between two precast concrete columns 1 on the line, thereby ensuring the track gauge. Specifically, the steel bar 6 passes through the hole 8 and out of the base steel plate 3 and slides along the slot 9, thereby adjusting the position of the precast concrete column 1 in the vertical line direction.

[0023] In this embodiment, if Figure 1 As shown, a height adjustment nut and a washer 4 are provided between the foundation steel plate 3 and the embedded steel plate 5, and the verticality of the precast concrete column 1 can be adjusted by the height adjustment nut and the washer 4. After the adjustment is completed, concrete 7 is used to fill and seal.

[0024] Although the above embodiments have described the concepts and embodiments of the purpose of the utility model in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the utility model without departing from the scope of the claims, so they are not described one by one here.
