DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0025] See also Figures 1 to 6 In the embodiment of the present invention, the beam-column node connection device of the assembled reinforced concrete frame includes a first threaded sleeve 1 and fixed blocks respectively connected at both ends of the first threaded sleeve 1. A partition 8 is fixedly connected to the middle of the inner wall of the first threaded sleeve 1, and the left and right sides of the partition 8 are fixedly connected to the second threaded sleeve 3 that matches the connecting rod 2 to be connected. The surfaces of the two second threaded sleeves 3 are sleeved with first limiting rings 4 that are clamped and matched with the clamping sleeve 9. The inner wall of the second threaded sleeve 3 is threadedly connected to the connecting rod 2, and the surface of the connecting rod 2 is threadedly connected to the first fixed block 6. The first fixed block 6 is fixedly connected to the second fixed block 7 on the side close to the first threaded sleeve 1. The second fixed block 7 is threadedly connected to the first threaded sleeve 1. The second fixed block 7 is fixedly connected to the tubular clamping sleeve 9 on the side close to the first threaded sleeve 1. The clamping sleeve 9 is clamped with the first limiting ring 4. The surface of the clamping sleeve 9 is provided with annularly distributed deformation grooves. The first limiting ring 4 is a wedge-shaped block annularly distributed along the surface of the second threaded sleeve 3, and the wedge-shaped block matches the deformation groove. The clamping sleeve 9 is a stainless steel material component.

[0026] exist Figure 3 In the figure, the first fixed block 6 and the second fixed block 7 are composed of a stepped cylinder to form an integral fixed block. The second fixed block 7 is provided with an external thread that cooperates with the first threaded sleeve 1. The axis is provided with a threaded hole that cooperates with the connecting rod 2 to be connected. The top and bottom of the first threaded sleeve 1 are both provided with two threaded holes 101, and the top and bottom of the second fixed block 7 are both provided with a second thread groove 701. The inner wall of the threaded hole 101 is threadedly connected with a second screw rod 11, and the second screw rod 11 passes through the threaded hole 101 and is threadedly connected with the second thread groove 701. The first screw rod 11, the threaded hole 101 and the second thread groove 701 constitute a connecting mechanism, and the first screw rod 11 cooperates with the threaded hole 101 and the second thread groove 701. By providing the second screw rod 11, the second fixed block 7 is tightly connected to the first threaded sleeve 1, which has an anti-falling effect.

[0027] exist Figure 5 In the embodiment, a first thread groove 601 is provided on the front of the first fixed block 6, and a first screw rod 10 is threadedly connected to the inner wall of the first thread groove 601. A notch 1001 is provided on the surface of the first screw rod 10, and the notch 1001 contacts the inner wall of the first fixed block 6. The first screw rod 10 and the first thread groove 601 provided on the first fixed block 6 constitute a rotation positioning mechanism. By providing the notch 1001, when the notch 1001 contacts the inner wall of the first fixed block 6, the first fixed block 6 can rotate freely, and when the notch 1001 no longer contacts the inner wall of the first fixed block 6, the position of the first fixed block 6 is limited, thereby achieving a limiting effect.

[0028] exist Figure 4 In the figure, a second fixing block 7 is fixedly connected to a side close to the first threaded sleeve 1 with a second limiting ring 5 wrapping the end of the clamping sleeve 9. The second limiting ring 5 is located on the outside of the clamping sleeve 9. By setting the second limiting ring 5, the possibility of the clamping sleeve 9 exceeding its own stiffness coefficient during clamping and thus breaking is avoided, thereby achieving a limiting effect.

[0029] The working principle of the present invention is as follows: the user first screws the first fixing block 6 to the surfaces of the two connecting rods 2 on the opposite side, and then rotates the first threaded sleeve 1 counterclockwise to make the second threaded sleeve 3 threadedly connected to the connecting rod 2. By setting the second threaded sleeve 3, the connecting rod 2 and the second threaded sleeve 3 are tightly connected, which plays an effective connection effect. After the connecting rod 2 and the second threaded sleeve 3 are connected to the specified position, the first fixing blocks 6 on both sides are screwed in the direction of the first threaded sleeve 1 to make the second fixing block 7 connected to the first threaded sleeve 1. By setting the second fixing block 7, the second fixing block 7 and the first threaded sleeve 1 are tightly connected, which plays a further connection effect. At the same time, the first limiting ring 4 opens the clamping sleeve 9, and the second fixing block 7 drives the clamping sleeve 9 to advance spirally. When the clamping sleeve 9 advances to the specified position, by setting the clamping sleeve 9, the clamping sleeve 9 is clamped with the first limiting ring 4, so that the second fixing block 7 and the first threaded sleeve 1 are more tightly connected, which plays an anti-falling effect. By setting the second limiting ring 5, it is avoided that the clamping sleeve 9 exceeds its own stiffness coefficient when clamping, thereby preventing the possibility of breaking, and playing a limiting effect. The clamping sleeve 9 clamps the first limiting ring 4, and then the first screw 10 is screwed to make the notch 1001 away from the connecting rod 2. By setting the notch 1001. When the notch 1001 contacts the inner wall of the first fixing block 6, the first fixing block 6 can rotate freely; when the notch 1001 no longer contacts the inner wall of the first fixing block 6, the position of the first fixing block 6 is limited, and the limiting effect is achieved, so that the first fixing block 6 cannot rotate. Then the second screw 11 is screwed into the second thread groove 701. By setting the second screw 11, the second fixing block 7 is tightly connected to the first thread sleeve 1, which has the effect of preventing it from falling off. Finally, the second fixing block 7 is fixed to complete the installation.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
