[0011] Preferably, as the above technical solution, the support portion is a plurality of triangular support blocks arranged at intervals along the circumferential direction of the sleeve.

[0012] Preferably, as the above technical solution, there are four rod portions.

[0013] Preferably, as the above technical solution, the expansion rings are evenly arranged at intervals on the outer wall of the rod portion.

[0014] Preferably, as the above technical solution, the number of the triangular support blocks is set to three.

[0015] The beneficial effects of the utility model are as follows:

[0016] (1) The utility model can increase the contact area between the rod part and the concrete by means of a plurality of expansion rings arranged at intervals on the outer wall of the rod part, thereby increasing the stability of the embedded bolt structure and reducing the possibility of bolt loosening;

[0017] (2) The utility model plays a role of support and positioning during the bolt installation process through the arranged footrests. Through the detachably arranged footrests, the footrests can be replaced according to specific situations to use the footrests with the best positioning and support effects.

[0020] For the purposes of making the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0021] Embodiment

[0022] As Figure 1 shown, Figure 1 Fig. shows the overall structural schematic diagram of the embedded bolt in the embodiment;

[0023] This device includes:

[0024] The rod part 10, a plurality of rod parts 10 are arranged vertically, and a threaded section 11 is arranged at the top of the rod part 10;

[0025] The expansion ring 21, a plurality of expansion rings 21 are arranged at intervals on the outer wall of the rod part 10;

[0026] The footrest 23, the footrest 23 is detachably arranged at the bottom end of the rod part 10.

[0027] Specifically, the expansion ring 21 is arranged as an annular shape, and the expansion ring 21 and the screw rod 10 are integrally formed by casting, which simplifies the manufacturing process; there are four rod parts 10; the expansion rings 21 are evenly arranged at intervals on the outer wall of the rod part 10.

[0028] Through a plurality of expansion rings 21 arranged at intervals on the outer wall of the rod part 10, the contact area between the rod part 10 and the concrete can be increased, thereby increasing the stability of the embedded bolt structure and reducing the possibility of bolt loosening.

[0029] The foot support 23 plays a role of support and positioning during the bolt installation process. With the removably arranged foot support 23, it is possible to replace the foot support 23 according to specific circumstances to use the foot support 23 with the best positioning and support effects.

[0030] As Figure 1 shown, Figure 1 Figure 7 shows the overall structural schematic diagram of the embedded bolt in the embodiment;

[0031] It further includes a reinforcing rod 22, and the reinforcing rod 22 is arranged between adjacent rod parts 10 and connects the two.

[0032] Specifically, the end parts of the reinforcing rod 22 are respectively arranged on one of the expansion rings 21 of the corresponding rod part 10. The reinforcing rod 22 plays a role in connecting multiple rod parts 10 and further increases the stability of bolt installation.
