[0005] A grouting-free sleeve connection device is characterized in that it includes a sleeve body and steel bars, reserved rebar insertion holes are respectively provided at both ends of the sleeve body, threaded holes are respectively provided on the side of the sleeve body and corresponding to the reserved rebar insertion holes, one end of the steel bar is provided with a reserved through hole, the end is located in the reserved rebar insertion hole, the reserved through hole and the threaded hole are aligned, and are tightened and connected by bolts.

[0006] The grouting-free sleeve connection device is characterized in that two reserved through holes are provided on the steel bar, and there are also two corresponding threaded holes on the side plate of the sleeve body.

[0007] The grouting-free sleeve connection device is characterized in that a gasket is provided between the bolt and the threaded hole.

[0008] The grouting-free sleeve connection device is characterized in that a protruding cylinder is provided on one side of the sleeve body, a threaded hole connected to the sleeve body is provided in the cylinder, and the bolt is tightened by passing through the threaded hole and the reserved reinforcing bar hole.

[0009] The beneficial effect of the utility model is: it can be seen from the above technical scheme that the present application provides a grouting-free sleeve connection device, which uses a sleeve mechanical connection method to connect the prefabricated section and the steel bars at the end to be connected, avoiding the connection defect problem caused by incomplete grouting when using a grouting sleeve.

[0010] The present invention effectively connects the steel bar and the sleeve by tightening bolts, has a simple structure, high working efficiency, and is suitable for popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0012] Figure 1 It is a three-dimensional schematic diagram of the sleeve of the utility model;

[0013] Figure 2 It is a cross-sectional view of the sleeve of the utility model;

[0015] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the embodiments of the present application are within the scope of protection requested by the present application.

[0016] like Figure 1-3 As shown: a grouting-free sleeve connection device, which includes a sleeve body 1 and a steel bar 2, wherein reserved reinforcement holes 3 are respectively provided at both ends of the sleeve body, and threaded holes 4 are respectively provided on the side of the sleeve body and corresponding to the reserved reinforcement holes, one end of the steel bar is provided with a reserved through hole, and the end is located in the reserved reinforcement hole, the reserved through hole and the threaded hole are aligned, and are tightened and connected by a bolt 5; two reserved through holes are provided on the steel bar, and there are also two corresponding threaded holes on the side plate of the sleeve body; a gasket 6 is provided between the bolt and the threaded hole.

[0017] Furthermore, a protruding cylinder 7 is provided on one side of the sleeve body, and a threaded hole communicating with the sleeve body is provided in the cylinder, and the bolt is tightened by passing through the threaded hole and the reserved reinforcing bar hole.

[0018] The steps to use are as follows:

[0019] Step 1: When the prefabricated component is produced, a perforation is reserved at the required position of one end of the steel bar connected to the sleeve, and the sleeve is connected to the steel bar with bolts;

[0020] Step 2: Cast the prefabricated component so that the reserved reinforcing bar hole and the side threaded hole at the other end of the sleeve are exposed on the surface of the prefabricated component;

[0021] Step 3: During installation, treat the reserved dowel bars in the same way, insert them into the exposed section of the prefabricated component sleeve and tighten them with bolts.

[0022] The device effectively connects the steel bars inside the prefabricated component with the reserved steel bars to be connected using dry bolts. When the prefabricated component is produced, a perforation is reserved at the required position of one end of the steel bar connected to the sleeve, and then the steel bar at the perforated end is inserted into one end of the sleeve, so that the perforation of the steel bar and the threaded hole on the side of the sleeve are aligned, and then tightened with bolts. When pouring concrete, the reserved dowel hole and the threaded hole on the side of the sleeve are exposed; when installing on site, the end of the dowel reserved on site is treated in the same way and inserted into the exposed section of the prefabricated component sleeve. At the same time, the perforation of the dowel and the threaded hole on the side of the sleeve are aligned, and then tightened with bolts, and the connection is completed.

[0023] The above are only embodiments provided for the present application and are not intended to limit the present application. Although the present application is described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
