[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model. Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art in the field to which the present utility model belongs. The words such as "including" used herein mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects.

[0023] An embodiment of the present utility model provides a strengthened structure for a concrete embedded part, as Figure 1 shown, which includes a metal ring 1, a fiber sleeve 2, and a fiber bundle 3. The metal ring 1 is fixedly connected to the embedded part. At least one fiber sleeve 2 is arranged on the outer ring of the metal ring 1. The actual number of the fiber sleeves 2 can be set according to actual needs. A fiber bundle 3 is arranged inside the fiber sleeve 2.

[0024] Specifically, an arc-shaped groove is arranged on the outer ring of the metal ring 1, and the fiber sleeve 2 is connected in the arc-shaped groove of the metal ring 1.

[0025] Specifically, the fiber sleeve 2 is composed of multiple fiber round tubes connected in parallel and a locking member 21. The locking member 21 is used to tie up the fiber round tubes.

[0026] Specifically, the fiber bundle 3 is composed of several fiber tubes, and both ends of the fiber bundle 3 are spread out circumferentially outward.

[0027] In some embodiments, as Figure 2 shown, the side of the fiber sleeve 2 away from the metal ring 1 is spread out flatly outward.

[0028] In some embodiments, the fiber sleeve 2 can be snapped into the arc-shaped groove of the metal ring 1 by a snap connection method, or can be fixedly connected by an adhesive method, as long as the fiber sleeve 2 and the metal ring 1 can maintain the structural stability before concrete pouring.

[0029] In some embodiments, the embedded part is cylindrical and has the same outer diameter as the inner diameter of the metal ring 1.

[0030] In some embodiments, the shape of the metal ring 1 can be adjusted according to the shape of the embedded part. For example, if the embedded part is square, the metal ring 1 is adaptively adjusted to a square ring, as long as the inner diameter of the metal ring 1 is the same as the outer diameter of the embedded part and the metal ring 1 can be sleeved on the embedded part.

[0031] In some embodiments, the shape of the metal ring 1 can be any solid, which is used for pre-patch connection at the bottom and top of the embedded part.

[0032] In some embodiments, as Figures 3 - 4 shown, after the embedded part and the strengthening structure of the present embedded part are installed, concrete is poured. During the pouring process of the concrete, the scattered fiber bundles 3 will to a certain extent hinder the falling of the concrete, and there will be a situation where no concrete flows into the lower side of the fiber bundles 3. Therefore, according to the downward acting force of the concrete poured on the fiber bundles 3, the present utility model provides an adaptive deformation structure to improve the possible problems.

[0033] Specifically: the central parts of several fiber tubes of the fiber bundle 3 are connected by a connecting disc 34. A first connecting rod 33 and a second connecting rod 35 are slidably connected in the connecting disc 34. The first connecting rod 33 is slidably connected to the adjacent second connecting rod 35. Swing rods 32 are rotatably connected to the opposite sides of the first connecting rod 33 and the second connecting rod 35. Mounting seats 31 are arranged at the ends of the fiber tubes. The side of the swing rod 32 far from the connecting disc 34 is rotatably connected to the mounting seat 31; when the concrete is poured downward, some of the upper fiber tubes are bent horizontally under the corresponding acting force, so that the mounting seat 31 drives the swing rod 32 to rotate, thereby causing the first connecting rod 33 or the second connecting rod 35 to move inward, and the overall expansion range of the end of the fiber bundle 3 is reduced, which can reduce the resistance to the concrete.

[0034] In some embodiments, as Figure 5 shown, a torsion spring 36 is connected between the swing rod 32 and the adjacent first connecting rod 33, and a torsion spring 36 is also connected between the swing rod 32 and the adjacent second connecting rod 35; the torsion spring 36 can make the swing rod 32 have a resilience and a restoring force, so that the fiber tube can be restored to a certain extent, ensuring the strengthening structure of the fiber bundle 3, and the resilience enables the swing rod 32 to drive the fiber bundle 3 to swing by a certain amplitude to shake off the concrete.

[0035] In some embodiments, as Figure 6 shown, a number of balls 37 are arranged on the sides of the first connecting rod 33 and the second connecting rod 35 close to the connecting disc 34. Symmetrically distributed top beads 38 are arranged on the side of the connecting disc 34 close to the balls 37. Elastic members are connected between the top beads 38 and the connecting disc 34. The top beads 38 are in extrusion fit with the corresponding balls 37; during the process of the first connecting rod 33 or the second connecting rod 35 moving inward, it will drive the balls 37 to move inward, so that the balls 37 are in extrusion fit with the top beads 38, thereby generating a certain vibration, and the concrete can be shaken off through the vibration, and the full contact between the fiber bundle 3 and the concrete can be ensured, preventing the unevenness of the concrete below the fiber bundle 3 due to the blockage of the fiber bundle 3.

[0036] In some embodiments, the present invention also discloses one of the installation methods of the reinforced structure of the concrete embedded part, specifically including:

[0037] S1: Install the embedded part in the concrete;

[0038] S2: Pass the metal ring 1 through the embedded part in the hole and fix it on the embedded part with a binder;

[0039] S3: Install the fiber sleeve 2 and the fiber bundle 3 on the metal ring 1;

[0040] S4: According to the size of the embedded part, install multiple reinforced structures of the embedded part in layers. Each layer of the reinforced structure of the embedded part rotates horizontally by a certain angle so that the vertical positions of the fiber bundles 3 of each reinforced structure of the embedded part are different, and then pour concrete to form.

[0041] Although the embodiments of the present invention have been described in detail above, it is obvious to those skilled in the art that various modifications and changes can be made to these embodiments. However, it should be understood that such modifications and changes fall within the scope and spirit of the present invention as described in the claims. Moreover, the present invention described herein can have other embodiments and can be implemented or realized in various ways.
