[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength composite precast concrete component with impact resistance, comprising a concrete component body, connecting grooves, grouting holes, positioning grooves, positioning elements, positioning holes, a base plate, an installation pipe, and spiral angled stirrups. The connecting grooves are distributed on the side ends of the concrete component body, the grouting holes are distributed at the bottom of the concrete component body, the positioning grooves are opened at the four corners of the bottom end of the concrete component body, the positioning elements are installed in the positioning grooves, the positioning holes are opened through the positioning elements, the base plate is connected to the four positioning elements inside the concrete component body, the bottom end of the installation pipe is fixed to the middle of the base plate, and the spiral angled stirrups are installed inside the concrete component body through the installation pipe.

[0006] Based on the above technical solution, the spiral angled stirrup includes a stirrup frame, connecting holes, spiral angled bars, a bracket, and a sleeve. The stirrup frame has connecting holes distributed along its edges. The spiral angled bars connect all the stirrup frames at equal intervals through the connecting holes. The bracket is installed inside the stirrup frame, and the sleeve is installed in the middle of the bracket and is slidably connected to the side end of the mounting pipe.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1 to 4 As shown, a high-strength composite precast concrete component with impact resistance includes a concrete component body 1, connecting grooves 2, grouting holes 3, positioning grooves 4, positioning elements 5, positioning holes 6, a base plate 7, an installation pipe 8, and spiral angled stirrups 9. The connecting grooves 2 are distributed on the side of the concrete component body 1, the grouting holes 3 are distributed at the bottom of the concrete component body 1, the positioning grooves 4 are opened at the four corners of the bottom of the concrete component body 1, the positioning elements 5 are installed in the positioning grooves 4, the positioning holes 6 are opened through the positioning elements 5, the base plate 7 is connected to the four positioning elements 5 inside the concrete component body 1, the bottom end of the installation pipe 8 is fixed to the middle of the base plate 7, and the spiral angled stirrups 9 are installed inside the concrete component body 1 through the installation pipe 8.

[0016] The spiral angled stirrup 9 includes a stirrup frame 10, connecting holes 11, spiral angled ribs 12, a bracket 13, and a sleeve 14. The connecting holes 11 are distributed on the edge of the stirrup frame 10. The spiral angled ribs 12 connect all the stirrup frames 10 at equal intervals through the connecting holes 11. The bracket 13 is installed inside the stirrup frame 10. The sleeve 14 is installed in the middle of the bracket 13 and is slidably connected to the side end of the mounting tube 8.

[0017] The spiral angled stirrup 9 provides impact-resistant support for the concrete component 1 under the support of the installation pipe 8.

[0018] The working principle of this invention is as follows: During installation, the concrete component 1 is positioned and installed against the pre-reserved steel bars on the ground using the bottom positioning component 5. Grouting is then performed on the concrete component 1 through the grouting hole 3 to complete the installation. The stirrup frame 10 inside the concrete component 1 is helically angled by the helical angled bars 12. This not only supports the concrete component 1 but also enhances its toughness. When subjected to external impact, the stirrup frame 10, with its helical angled bars 12, distributes the external force evenly according to biomimicry, and the force is transmitted to the installation pipe 8 through the bracket 13 for absorption, thereby improving impact resistance.

[0019] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
