Description

Technical Field

[0001] The utility model belongs to the technical field of buckling restraint support, and in particular relates to a double-yield point buckling restraint support structure. Background Art

[0002] The buckling restrained brace is composed of a core energy absorption section and an external restraint component. When the core energy absorption section is subjected to axial pressure, the external restraint unit is used to restrain the lateral deformation of the core energy absorption section to prevent the core energy absorption section from buckling, so that the entire cross-section can yield under the action of axial force and obtain symmetrical force performance in the tensile and compressive directions. The buckling restrained brace has the characteristics of clear shock absorption mechanism, obvious shock absorption effect, safety, reliability, and economic rationality, and can meet the seismic requirements of different structures.

[0003] However, there are some problems with the existing technology: when the yield steel plate of the existing core energy absorption section is connected to the clamp plate, it is connected together using several groups of bolts in several groups of threaded holes in the clamp plate and the yield steel plate. However, the process of using bolts is relatively cumbersome and inconvenient to connect together. Therefore, we propose a double yield point buckling restrained support structure.

[0030] The two ends of the first yield steel plate 1 and the second yield steel plate 2 are respectively placed in the two groups of clamps 5, and the first insertion hole, the second insertion hole, the third insertion hole and the fourth insertion hole are matched together. When the matching is completed, the staff then operates the buckle assembly 8 to insert the lower end of the insertion rod 6 through the first insertion hole, the second insertion hole, the third insertion hole and the fourth insertion hole. After the insertion, the position of the insertion rod 6 is finally fixed by the buckle assembly 8, thereby realizing the first yield steel plate 1 and the second yield steel plate 2. The function of being convenient for fixing and connecting in the clamp 5 is achieved. In addition, the outer sleeve steel pipe 3 is sleeved on the first yield steel plate 1 and the second yield steel plate 2, so as to constrain the lateral deformation of the first yield steel plate 1 and the second yield steel plate 2 to prevent the first yield steel plate 1 and the second yield steel plate 2 from buckling.

[0031] A positioning hole is provided on the lower end surface of the insertion rod 6, and the mounting plate 4 is arranged in a T shape.

[0032] Specifically, the buckle assembly 8 includes two groups of mounting frames 801, one side of which is fixedly mounted on one side of the mounting plate 4, and one side of the other group of mounting frames 801 is fixedly mounted on one side of the fixed plate 7, and sliders 802 are slidably arranged in both groups of mounting frames 801; a connecting plate 803 is arranged between the two groups of sliders 802, and a positioning rod 804 is fixedly mounted on one end of the connecting plate 803; the positioning rod 804 and the insertion hole are arranged correspondingly, and a pull rod 805 is fixedly mounted on the other end of the connecting plate 803; a mounting hole is opened at one end of the mounting frame 801, and a sliding sleeve 806 is fixedly mounted in the mounting hole, and a guide rod 807 is slidably mounted in the sliding sleeve 806; a reset spring 808 is elastically connected to one end of the slider 802, and one end of the reset spring 808 is fixedly mounted on one end of the sliding sleeve 806; one end of the positioning rod 804 is inserted through the positioning hole through the reset spring 808.

[0033] The staff pulls the pull rod 805 to drive the connecting plate 803 to move toward the sliding sleeve 806. The movement of the connecting plate 803 drives the positioning rod 804 to move and drives the slider 802 to slide in the installation frame 801. The sliding of the slider 802 drives the return spring 808 to be compressed and drives the guide rod 807 to slide in the sliding sleeve 806. When the positioning rod 804 moves into the sliding sleeve 806, the lower end of the insertion rod 6 is then inserted through the first insertion hole, the second insertion hole, the third insertion hole and the fourth insertion hole. After the insertion, the pull rod 805 is finally relaxed. Due to the action of the return spring 808, one end of the positioning rod 804 will be inserted through the positioning hole, thereby fixing the position of the insertion rod 6. In addition, the guide rod 807 slides in the sliding sleeve 806, so that the sliding position of the slider 802 is guided and will not move out of the installation frame 801.
