Description

Technical Field

[0001] This utility model relates to the field of rebar connecting sleeve technology, and in particular to a high-strength rebar connecting sleeve anti-disengagement structure. Background Technology

[0002] In the field of construction engineering, high-strength steel bar connections are widely used in various building structures to ensure the stability and load-bearing capacity of the structure. Steel bar connection sleeves are key components for connecting steel bars.

[0003] However, in the existing technology, the existing rebar connecting sleeves mainly achieve the connection of rebars through threaded connection. However, in actual engineering, due to the influence of factors such as vibration, impact and temperature change on the structure, the threaded connection is prone to loosening, which can lead to the rebar coming out of the sleeve and seriously affect the structural safety. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing rebar connecting sleeves mainly achieve rebar connection through threaded connection. However, in actual engineering, due to the influence of factors such as vibration, impact, and temperature changes on the structure, the threaded connection is prone to loosening, which leads to the rebar coming out of the sleeve and seriously affects the structural safety. Therefore, a high-strength rebar connecting sleeve anti-disengagement structure is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength steel bar connecting sleeve anti-disengagement structure, comprising a sleeve body, a connecting hole through the center of both ends of the sleeve body, a threaded groove on the inner wall of the connecting hole, a fixing groove on the outer wall of the middle part of the sleeve body, a hexagonal block rotatably connected to the outer walls of both ends of the sleeve body, a movable hole on the inner wall of the connecting hole, a telescopic groove inside the sleeve body, the interior of the telescopic groove communicating with the interior of the connecting hole through the movable hole, an anti-disengagement top rod movably connected to the inner wall of the telescopic groove, a threaded ring plate threadedly connected to the outer wall of the anti-disengagement top rod, and the threaded ring plate fixedly connected to the inner wall of the hexagonal block.

[0006] Preferably, the outer wall of the sleeve body is provided with a rotating groove, and the hexagonal block and the threaded ring plate are rotatably connected to the inner wall of the rotating groove.

[0007] Preferably, a rubber block is fixedly connected to the inner wall of the connecting hole.

[0008] Preferably, the inner wall of the threaded ring plate is fixedly connected with an internal thread.

[0009] Preferably, the outer wall of the anti-detachment top rod is provided with a second threaded groove, and the anti-detachment top rod is threadedly connected to the internal thread through the second threaded groove.

[0010] Preferably, an anti-slip pad is fixedly connected to the outer wall of one end of the anti-detachment top rod.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the sleeve body is rotated by using a wrench to clamp the fixing groove, so that the steel bar is connected into the connection hole. After the connection is completed, the hexagonal block is rotated to drive the threaded ring plate to rotate synchronously, so that the anti-disengagement rod in the telescopic groove extends out from the movable hole, thereby squeezing and applying pressure to the steel bar connected in the connection hole. When the steel bar is subjected to tension or other external forces and has a tendency to come out, the interaction between the threaded ring plate and the anti-disengagement rod and the steel bar is used to prevent the steel bar from continuing to move, so as to play the role of preventing disengagement, thereby improving the connection firmness of the steel bar.

[0013] 2. In this utility model, the rotation of the hexagonal block and the threaded ring plate is limited by the setting of the rotating groove, which makes it easier for the threaded ring plate to better control the extension and retraction of the anti-detachment rod. The anti-slip pad at the end of the anti-detachment rod further improves the friction between the anti-detachment rod and the surface of the reinforcing bar. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a high-strength rebar connecting sleeve anti-disengagement structure, including a sleeve body 1, with connecting holes 2 penetrating through the center of both ends of the sleeve body 1, threaded grooves 21 formed on the inner wall of the connecting holes 2, a fixing groove 3 formed on the outer wall of the middle part of the sleeve body 1, and hexagonal blocks 4 rotatably connected to the outer walls of both ends of the sleeve body 1. A movable hole 22 is formed on the inner wall of the connecting holes 2, and a telescopic groove 12 is provided inside the sleeve body 1. The interior of the telescopic groove 12 communicates with the interior of the connecting holes 2 through the movable hole 22. An anti-disengagement top rod 6 is movably connected to the inner wall of the telescopic groove 12, and a threaded ring plate 5 is threadedly connected to the outer wall of the anti-disengagement top rod 6. The threaded ring plate 5 is fixedly connected to the inner wall of the hexagonal block 4.

[0021] The specific settings and functions of this embodiment are described below. By using a wrench to rotate the sleeve body 1 through the setting of the fixing groove 3, the steel bar is connected into the connecting hole 2. After the connection is completed, the hexagonal block 4 is rotated to drive the threaded ring plate 5 to rotate synchronously, so that the anti-disengagement rod 6 in the telescopic groove 12 extends out from the movable hole 22, thereby squeezing and applying pressure to the steel bar connected in the connecting hole 2. When the steel bar is subjected to tension or other external forces and has a tendency to come out, the interaction between the threaded ring plate 5 and the anti-disengagement rod 6 and the steel bar is used to prevent the steel bar from continuing to move, thereby playing the role of preventing disengagement and improving the connection firmness of the steel bar.

[0022] Example 2: Figure 1 - Figure 3 As shown, the outer wall of the sleeve body 1 is provided with a rotating groove 11. The hexagonal block 4 and the threaded ring plate 5 are rotatably connected to the inner wall of the rotating groove 11. The inner wall of the connecting hole 2 is fixedly connected with a rubber block 23. The inner wall of the threaded ring plate 5 is fixedly connected with an internal thread 51. The outer wall of the anti-detachment rod 6 is provided with a threaded groove 61. The anti-detachment rod 6 is threadedly connected to the internal thread 51 through the threaded groove 61. An anti-slip pad 62 is fixedly connected to the outer wall of one end of the anti-detachment rod 6.

[0023] The overall effect of this embodiment is that the rotation of the hexagonal block 4 and the threaded ring plate 5 is limited by the setting of the rotating groove 11, which makes it easier for the threaded ring plate 5 to better control the extension and retraction of the anti-detachment rod 6. The anti-slip pad 62 at the end of the anti-detachment rod 6 further increases the friction between the anti-detachment rod 6 and the surface of the reinforcing bar. The rubber block 23 fills the gap between the end of the reinforcing bar and the inner wall of the connecting hole 2, thereby improving the stability of the connection.

[0024] The usage and working principle of this device are as follows: When in use, the sleeve body 1 is inserted into the reinforcing bars through the connecting holes 2 at both ends. The sleeve body 1 is rotated to connect with the reinforcing bars through the fixing groove 3 using a wrench. After the connection is completed, the hexagonal block 4 is rotated to drive the threaded ring plate 5 to rotate synchronously, so that the anti-detachment rod 6 in the telescopic groove 12 extends out from the movable hole 22, thereby squeezing and applying pressure to the reinforcing bars connected in the connecting hole 2. When the reinforcing bars are subjected to tension or other external forces and have a tendency to come out, the interaction between the threaded ring plate 5 and the anti-detachment rod 6 and the reinforcing bars prevents the reinforcing bars from continuing to move.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
