In the figure:

10. a sleeve body; 20. a partition plate; 30. a grid member; 11. grouting holes; 12. a groove; 13. a rib; 21. a feed through hole; 22. and (4) air holes.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the grouting sleeve of the present invention includes a sleeve body 10, a partition plate 20 disposed on the top end of the sleeve body 10, and a grid member 30 disposed in the sleeve body 10 and under the partition plate 20.

The sleeve body 10 is cylindrical, and may be square cylindrical. The sleeve body 10 may be a steel cylinder, and a grouting hole 11 extending along an axial direction thereof is formed therein, so that high-strength mortar is injected through the grouting hole 11 to be combined with the sleeve body 10.

The sleeve body 10 forms grooves 12 and ribs 13 alternately arranged on the inner surface of the grouting hole 11, wherein the grooves 12 and the ribs 13 are respectively annular and alternately arranged along the longitudinal direction of the sleeve body. The cross section of each convex rib 13 is isosceles trapezoid, and the height thereof is 0.24 mm. The cross section of each groove 12 is also an isosceles trapezoid, and the extension lines of the two waists of the isosceles trapezoid where the grooves are located are vertically intersected. The arrangement of the convex ribs 13 and the grooves 12 in the sleeve body 10 can enhance the connection between the sleeve body and the high-strength mortar, so that the transmission of force between the high-strength mortar and the sleeve body 10 is facilitated.

In specific implementation, the structure of the sleeve body 10 is not limited by this embodiment, and the inside of the sleeve body 10 may be a structure of the groove 12 and the protruding rib 13, or a plurality of protruding blocks may be disposed on the inner surface of the grouting hole 11 of the sleeve body 10 at equal intervals along the longitudinal direction thereof. Each lug is of an annular structure, the cross section of each lug can be in a right trapezoid shape, the lower bottom of each lug is connected with the sleeve body, the right-angled waist is located above the sleeve body, and the oblique waist is located below the sleeve body.

The partition plate 20 is a plate body, and the outer diameter thereof is larger than that of the sleeve body 10. The middle part of the clapboard 21 is provided with a material passing hole 21. The partition plate 20 is uniformly provided with a plurality of ventilation holes 22 at the periphery thereof and at the periphery of the inner side of the sleeve body 10.

The grid member 30 is a mesh member formed of reinforcing bars arranged crosswise to the longitudinal direction, and is blocked on the inner wall of the sleeve body 10 and is arranged adjacent to the lower side of the partition 20. The grid member 30 is spaced from the separator 20 by a distance of 5-10 cm. The mesh holes in the mesh member 30 are the same size.

During grouting, concrete mortar enters from the bottom end of the sleeve body 10 through the grouting holes 11, rises to the position of the grid component 30, is blocked by the grid component 30 and then is positioned at the position of the partition plate 20, then passes through the through holes 21 in the middle of the partition plate 20, and small air bubbles in the concrete mortar are discharged through the air holes 22, so that the concrete mortar is prevented from forming large air bubbles after passing through the partition plate 20 to influence the performance of the concrete mortar. The grouting sleeve is simple in structure, convenient and practical.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
