Description

Technical Field

[0001] The present application relates to the technical field of steel bar connection, and in particular to a steel bar connection joint. Background Art

[0002] In construction, we often encounter the problem of interconnection between steel bars. There are three main ways to connect steel bars: binding, mechanical connection, and welding. Among them, welding cannot guarantee its connection quality and is difficult to construct due to space limitations on the construction site. Therefore, this method is generally not used in construction.

[0003] However, although the steel bar binding connection is convenient to use, the connection firmness cannot be well guaranteed by only relying on two sections of binding wires. Although the mechanical connection is firmly installed, it is necessary to process the threads at the ends of the steel bars in advance and butt the steel bar threads on site. Moreover, since the steel bars are very long, the butt connection operation will be laborious and the connection efficiency will be low. In addition, the connection end faces of the steel bars are not visible during the connection process, and the yield rate cannot be guaranteed. Utility Model Content

[0004] In order to make the steel bar connection not only easy to install but also firmly connected, the present application provides a steel bar connection joint.

[0005] A steel bar connection joint provided in the present application adopts the following technical solution: it includes a left base block and a right base block, the left base block is fixedly connected to the right base block, the two have the same structure and are symmetrically arranged, a left fixed block is arranged at the side end of the left base block, and a right fixed block is arranged at the side end of the right base block, the left fixed block and the right fixed block have the same structure and are symmetrically arranged, and a fixing rod is arranged between the left fixed block and the right fixed block.

[0006] Optionally, a first tooth groove is provided inside the left base block and the right base block, and a blocking block is fixedly connected to the side ends of the left base block and the right base block.

[0007] Optionally, a second tooth groove is provided inside the left fixing block and the right fixing block, and the first tooth groove and the second tooth groove are combined to form a fixing hole, and the diameter of the fixing hole is slightly smaller than the diameter of the steel bar.

[0008] Optionally, the upper and lower ends of the left fixed block are fixedly connected to the left adjusting tube, and the upper and lower ends of the right fixed block are fixedly connected to the right adjusting tube. Thread grooves are provided inside the left adjusting tube and the right adjusting tube, and the thread directions of the thread grooves inside the left adjusting tube and the right adjusting tube connected to the same fixing rod are opposite.

[0009] Optionally, thread grooves are provided at both ends of the fixing rod, the thread directions of the two thread grooves are opposite, and the thread grooves at both ends are respectively engaged with the left adjustment tube and the right adjustment tube, and the fixing rods are placed in reverse directions in the same transverse and longitudinal directions.

[0010] Optionally, a baffle is fixedly connected to a side end of the fixing rod, an adjusting head is fixedly connected to the side end of the fixing rod, and a hexagonal hole is opened at the center of the adjusting head.

[0011] Optionally, a first gasket is sleeved on the outer end of the fixing rod, and a second gasket is sleeved on the outer end of the fixing rod. The first gasket and the second gasket have the same structure and are tightly attached to each other and are symmetrically arranged.

[0012] Optionally, large tooth surfaces are provided on the side ends of the first gasket and the second gasket, and the large tooth surfaces of the first gasket and the second gasket are meshed. Small tooth surfaces are provided on the side ends of the first gasket and the second gasket, and the small tooth surfaces of the first gasket and the second gasket are respectively tightly attached to the left adjusting tube, the right adjusting tube and the adjusting head.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. Insert two sections of steel bars into the fixing holes formed by the left base block and the left fixed block, and the right base block and the right fixed block respectively, and then rotate the fixing rod by means of a tool. The fixing rod rotates, and the threaded grooves at both ends thereof cooperate with the left adjusting tube and the right adjusting tube respectively, so that the left fixing block and the right fixing block can be gathered toward the center, thereby clamping the two steel bars and fixing the steel bars. The device adopts a combination of binding and mechanical connection, which has the advantages of convenient use of binding and firm fixation of mechanical connection, thereby solving the problems of the existing connection method of steel bars, namely, loose binding, complicated machine connection operation and low efficiency.

[0015] 2. By arranging the first gasket and the second gasket on the fixing rod, the fixing rod can be prevented from loosening, thereby ensuring the firmness of the steel bar connection. Specifically, when the fixing rod is fixed, the two large tooth surfaces fix it by mutual tension rather than friction, so it will not loosen due to vibration. Moreover, since the inclination angle of the large tooth surface is greater than the pitch of the fixing rod thread, a "wedge effect" will be generated at the lower end of the adjusting head. Even if the steel bar keeps shaking, the fixing rod will not loosen, which can make the steel bar connector have the advantages of being firmly installed and not loosening.

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-5 This application is described in further detail.

[0023] The present application embodiment discloses a steel bar connection joint. Figure 1 , Figure 3 As shown, it includes a left base block 1 and a right base block 2. The left base block 1 and the right base block 2 are fixedly connected. The two have the same structure and are symmetrically arranged. The side ends of the left base block 1 and the right base block 2 are both in a semicircular groove state, and a first tooth groove 6 is opened inside. A threaded groove is opened inside the first tooth groove 6 to increase friction and enable better connection with the steel bar.

[0024] See also Figure 1 , Figure 3 A left fixing block 3 is provided at the side end of the left base block 1, and a right fixing block 4 is provided at the side end of the right base block 2. The left fixing block 3 and the right fixing block 4 are used to install and fix the steel bars, and their structures are the same and are symmetrically arranged. The side ends of the left base block 1 and the right base block 2 are fixedly connected with a blocking block 7, which can not only prevent the left fixing block 3 and the right fixing block 4 from being excessively retracted, but also can restrain the positions of the left fixing block 3 and the right fixing block 4 so that they can be flush with the left base block 1 and the right base block 2. A second tooth groove 8 is provided inside the left fixing block 3 and the right fixing block 4, and a threaded groove is provided inside the second tooth groove 8 to increase friction and better connect with the steel bar. The first tooth groove 6 and the second tooth groove 8 are combined to form a fixing hole 9, and the fixing hole 9 is used to install and fix the steel bar. The diameter of the fixing hole 9 is slightly smaller than the diameter of the steel bar, which can better lock the steel bar and avoid gaps between the two.

[0025] See also Figure 1 , Figure 3A fixing rod 5 is provided between the left fixing block 3 and the right fixing block 4. The fixing rod 5 is used to drive the left fixing block 3 and the right fixing block 4 to converge toward the center to fix the steel bar. The upper and lower ends of the left fixing block 3 are fixedly connected to the left adjusting tube 10, and the upper and lower ends of the right fixing block 4 are fixedly connected to the right adjusting tube 11. The left adjusting tube 10 and the right adjusting tube 11 are provided with thread grooves inside, and the thread directions of the thread grooves inside the left adjusting tube 10 and the right adjusting tube 11 connected to the same fixing rod 5 are opposite.

[0026] See also Figure 4 , thread grooves are provided at both ends of the fixing rod 5, and the thread directions of the two thread grooves are opposite, and the thread grooves at both ends are respectively engaged with the left adjusting tube 10 and the right adjusting tube 11, so that when the fixing rod 5 is rotated, the fixing rod 5 can cooperate with the left adjusting tube 10 and the right adjusting tube 11 at the same time, thereby driving the left fixing block 3 and the right fixing block 4 to move toward the center, and the fixing rod 5 is reversed in the same horizontal and longitudinal directions of the fixing rod 5, so as to prevent the fixing rod 5 on the same side from being deflected, so as to better fix it, and the side end of the fixing rod 5 is fixedly connected with a baffle 12, and the baffle 12 is used to prevent the fixing rod 5 from falling off from the left adjusting tube 10 and the right adjusting tube 11, which can be convenient for installation, and the side end of the fixing rod 5 is fixedly connected with an adjusting head 13, and the adjusting head 13 is octagonal, which is convenient for the staff to use a wrench or pliers to rotate, and a hexagonal hole 14 is provided in the center of the adjusting head 13, and the setting of the hexagonal hole 14 enables the staff to use an electric drill and a hexagonal hole to rotate the fixing rod 5, which can not only improve the work efficiency, but also reduce the labor intensity of the staff.

[0027] See also Figure 4 , Figure 5 A first gasket 15 is sleeved on the outer end of the fixing rod 5, and a second gasket 16 is sleeved on the outer end of the fixing rod 5. The first gasket 15 and the second gasket 16 have the same structure and are symmetrically arranged close together. Large tooth surfaces 17 are arranged on the side ends of the first gasket 15 and the second gasket 16, and the large tooth surfaces 17 of the first gasket 15 and the second gasket 16 are meshed. After the fixing rod 5 is fixed, the two large tooth surfaces 17 are fixed by mutual tension (the so-called bolts that never loosen, which is the prior art). Small tooth surfaces 18 are arranged on the side ends of the first gasket 15 and the second gasket 16, and the small tooth surfaces 18 of the first gasket 15 and the second gasket 16 are respectively close to the left adjusting tube 10, the right adjusting tube, and the adjusting head 13, which can prevent the fixing rod 5 from sliding.

[0028] The implementation principle of a steel bar connection joint in the embodiment of the present application is as follows: two sections of steel bars are respectively inserted into the fixing holes 9 formed by the left base block 1 and the left fixing block 3, and the right base block 2 and the right fixing block 4, and then the fixing rod 5 is rotated by the tool and the adjusting head 13, and the fixing rod 5 is rotated so that the thread grooves at both ends thereof cooperate with the left adjusting tube 10 and the right adjusting tube 11 respectively, thereby driving the left fixing block 3 and the right fixing block 4 to move so that they gradually converge toward the center, and the diameter of the fixing hole 9 is slightly smaller than the diameter of the steel bar and has a first tooth groove 6 and a second tooth groove 8, which are used to increase the friction force, so that the two steel bars can be clamped and fixed;

[0029] When the fixing rod 5 is fixed, the two large tooth surfaces 17 fix it by mutual tension rather than friction, so it will not loosen due to vibration. Moreover, since the inclination angle of the large tooth surface 17 is greater than the pitch of the thread of the fixing rod 5, a "wedge effect" will be generated at the lower end of the adjusting head 13, so that even if the steel bar keeps shaking, the fixing rod 5 will not loosen.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
