Detailed Description

The utility model will be described in detail below with reference to the drawings in connection with embodiments. It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. For convenience of description, the words "upper", "lower", "left" and "right" are used hereinafter to denote only the directions corresponding to the upper, lower, left, and right directions of the drawings, and do not limit the structure.

As shown in fig. 2-4, the pre-buried sleeve provided in this embodiment includes a cylinder 11 and internal threaded holes 12 separately provided at two ends of the cylinder 11. The cross section of the cylinder 11 is circular, and the cylinder has an axial length L, if phi 25mm is arranged between the cylinders 11, the aperture of the internal threaded hole 12 is phi 16mm, so that the wall of the internal threaded hole 12 is thick, and the connection stability is improved. The outer surface of the cylinder 11 is provided with ribs 13 and patterns 14. The ribs 13 extend in the axial direction, and the ribs 13 are disposed on two opposite sides of one of the cylinder 11. The tail end of the convex rib 13 is arc-shaped.

The patterns 14 are arranged at intervals along the axial direction of the cylinder 11 to form a group, and two groups of patterns 14 are arranged on the other two opposite sides of the cylinder 11. The patterns 14 in the same group are inclined in one direction. The pattern 14 is in the shape of a blade.

As shown in fig. 5 and 6, the present utility model further provides a prefabricated component connection structure, which includes the first component 2, the second component 3, the third component 4 and the embedded sleeve 1. The first member 2 and the second member 3 are horizontally opposed, and the third member 4 is interposed between the first member 2 and the second member 3.

The embedded sleeve 1 is embedded in a plurality of parts in the thickness of the third member 4, the third member 4 is provided with counter bores 41 at two ends of the embedded sleeve 1, and the counter bores 41 are communicated with the internal threaded holes 12, so that the internal threaded holes 12 of the embedded sleeve 1 are exposed out of the surface of the third member 4. I.e. the thickness of the third member 4 is equal to the sum of the axial length L of the pre-buried sleeve 1 and the thickness of the two counter bores 41.
