Detailed implementation mode

[0025] Hereinafter, embodiments of the technical solution of the present utility model will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and thus are only examples and cannot be used to limit the protection scope of the present utility model. The specific structure of the present utility model is as Figures 1-6 shown in the figure.

[0026] A buckling-restrained brace structure includes an upper connection seat 1. On both sides below the upper connection seat 1, two buckling-restrained units are symmetrically arranged. The bottom of each buckling-restrained unit is connected to the lower connection seat 2 below it. A displacement adjustment unit is provided on each lower connection seat 2. In the installed state, the upper connection seat 1 and each lower connection seat 2 are fixed to the building 3 at their respective corresponding positions. The tops of the two buckling-restrained units are respectively movably hinged to the upper ear seats 4 fixedly connected to the corresponding positions at the bottom of the upper connection seat 1. A horizontal strengthening component is cooperatively installed between the two buckling-restrained units; in the present utility model, the entire buckling-restrained brace structure adopts two relatively arranged buckling-restrained units, which can achieve the purpose of supporting the upper and lower buildings 3. The inclined supports on both sides form multi-point supports, which can effectively ensure the stability of the entire structure; at the same time, under the action of the horizontal support in the middle of the horizontal strengthening component, it can effectively ensure the control of the lateral tension on the two buckling-restrained units.

[0027] In any of the above solutions, preferably, the buckling-restrained unit includes a buckling-restrained brace body 5. The upper end of the buckling-restrained brace body 5 is inclined inward, and the lower end is inclined outward. At the top of the buckling-restrained brace body 5, a fixed earring part 501 that is movably hinged to the upper ear seat 4 above it is integrally fixed. The bottom of the buckling-restrained brace body 5 is fixed to the top of the lower connection seat 2.

[0028] In the present utility model, the two buckling restraint units are respectively realized by two buckling restraint support bodies 5 arranged relatively obliquely, and are fixedly connected at the bottom through a lower connecting seat 2. The fixed cooperation of the lower points and the upper activities can effectively achieve the purpose of slightly limiting the position when there is a slight adjustment in the whole buckling restraint support body 5.

[0029] In any of the above solutions, preferably, the horizontal strengthening component includes a left-end sleeve 6 arranged horizontally. A right-end plug 7 is arranged on the right side of the left-end sleeve 6. A central insertion shaft 8 is integrally fixed to the left end of the right-end plug 7. The left end of the central insertion shaft 8 is movably inserted into the blind hole 9 of the left-end sleeve 6. A left flange 10 is fixed to the outer side wall of the right end of the left-end sleeve 6. A right flange 11 is fixed to the outer side wall of the left end of the right-end plug 7. The left flange 10 and the right flange 11 are coaxial and arranged at a relative interval. A left connecting ear seat 12 is fixed to the left end face of the left-end sleeve 6. A right connecting ear seat 13 is fixed to the right end face of the right-end plug 7. The left connecting ear seat 12 is movably hinged to a left fixed ear seat 14 fixed to the left buckling restraint support body 5. The right connecting ear seat 13 is movably hinged to a right fixed ear seat 15 fixed to the right buckling restraint support body 5. A plurality of tension connecting pieces are arranged along the circumference of the central insertion shaft 8. The left end of each tension connecting piece is fixed to the left flange 10, and the right end of each tension connecting piece is fixed to the right flange 11.

[0030] It should be noted that during installation, relying on the horizontal strengthening component mainly cooperates with the tension connecting pieces thereon to adjust the insertion length between the left-end sleeve 6 and the right-end plug 7, so as to achieve the purpose of adjusting the overall length of both ends of the whole horizontal strengthening component. Finally, lateral support is realized between the current two buckling restraint units, so that when the two buckling restraint units receive lateral component forces, it can play an auxiliary role in cooperating with the buckling restraint support body 5 to achieve support positioning, and further provide the lateral support stability of the whole buckling restraint support body 5 structure.

[0031] In any of the above solutions, preferably, the tension connecting piece includes a horizontally arranged double-headed stud 16. The left end of the double-headed stud 16 is screwed out through the corresponding threaded hole on the left flange 10. The right end of the double-headed stud 16 is screwed out through the corresponding threaded hole on the right flange 11. A left-end adjusting nut 17 is screwed on the external thread of the double-headed stud 16 on the left side of the left flange 10. The right end of the left-end adjusting nut 17 abuts against the outer side wall of the left flange 10. A right-end adjusting nut 18 is screwed on the external thread of the double-headed stud 16 on the right side of the right flange 11. The left end of the right-end adjusting nut 18 abuts against the outer side wall of the right flange 11.

[0032] The tension connecting piece mainly relies on the stud 16 to connect the left flange 10 and the right flange 11 on the left and right sides. Then, by using the left end adjusting nut 17 and the right end adjusting nut 18, the left flange 10 and the right flange 11 on both sides can be controlled and limited. In addition, by screwing and controlling each of the left end adjusting nut 17 and the right end adjusting nut 18, the purpose of quick locking or quick disassembly can be achieved, ensuring the convenience of operation.

[0033] In any of the above solutions, preferably, the displacement adjusting unit includes an inverted T-shaped groove 19 provided in the lower connecting seat 2 and penetrating through the thickness direction of the lower connecting seat 2. A horizontal wheel shaft 20 is fitted in the inverted T-shaped groove 19. The front and rear ends of the horizontal wheel shaft 20 both extend to the outside of the lower connecting seat 2 and are fixedly connected to the centers of the moving wheels 21 at their corresponding positions. The two moving wheels 21 are coaxially arranged, and in the moving state, the bottoms of the two moving wheels 21 are both lower than the bottom of the lower connecting seat 2.

[0034] Considering that the entire support structure needs to be displaced horizontally before installation, a displacement adjusting unit is provided here to assist the lifting equipment or manual pushing to complete the lateral displacement. When it is necessary to keep the entire displacement adjusting unit in a state of cooperating with the displacement of the entire structure, it relies on the moving wheels 21 to support on the plane between the buildings 3 at the bottom of the lower connecting seat 2, so as to achieve the purpose of quickly controlling the entire structure to be supported by each moving wheel 21, making the entire structure play a role of facilitating displacement.

[0035] In any of the above solutions, preferably, a plurality of threaded through holes are arranged at intervals along the thickness direction in the lower connecting seat 2 at the end of the horizontal section of the inverted T-shaped groove 19. An adjusting screw 22 is screwed into each threaded through hole. The inner ends of the adjusting screws 22 all extend into the corresponding inverted T-shaped groove 19 and respectively have a contact ball 23 fixedly installed at their ends. The inner ends of the contact balls 23 all abut against the outer side wall of the horizontal wheel shaft 20.

[0036] In any of the above solutions, preferably, a rotating handwheel 24 is fixedly installed at the outer end of each adjusting screw 22.

[0037] It should be noted that, considering that the bottom and top of the entire structure need to be installed separately when the horizontal shift is completed, the purpose of linking the rotation of the adjusting screw 22 by rotating the rotating hand wheel 24 is chosen here. When the adjusting screw 22 is rotated, it will achieve the purpose of shifting in the horizontal direction, so that the abutment ball 23 at its end is away from the outer wall of the horizontal wheel shaft 20, so that the two change from a tightly abutted state to a mutually separated state. When the abutment ball 23 retreats to the inside of the horizontal section on the other side of the vertical section of the inverted T-shaped groove 19, the horizontal wheel shaft 20 and the moving wheels 21 at both ends can be moved to the bottom of the vertical section of the inverted T-shaped groove 19. By pushing the horizontal wheel shaft 20 vertically upward, the bottom of the moving wheel 21 can be lifted upward and its bottom is higher than the bottom of the lower connecting seat 2, so that the moving wheel 21 can be stored. At this time, the entire shift adjustment unit is in an idle state, and the entire storage process is relatively convenient and simple to operate.

[0038] In any of the above solutions, it is preferred that the angle between the buckling restraining support body 5 and the horizontal plane is between 55° and 70°.

[0039] Setting the two buckling restraint support bodies 5 to appropriate tilt angles can reasonably control them after pre-installation so that each buckling restraint support body 5 can be subjected to downward pressure at the top to control the lateral component and the vertical component, thereby comprehensively improving the overall stability of the inclined relative structure formed by the two buckling restraint support bodies 5.

[0040] Specific working principle: In the whole buckling-restrained brace structure of the present utility model, two relatively arranged buckling-restrained units can achieve the purpose of supporting the upper and lower buildings 3, and the multi-point support formed by the inclined braces on both sides can effectively ensure the stability of the whole structure; meanwhile, under the action of the horizontal support in the middle of the horizontal strengthening component, it can effectively ensure the control of the lateral tension on the two buckling-restrained units; among them, the two buckling-restrained units respectively adopt two relatively inclined buckling-restrained brace bodies 5 to achieve cooperative support, and are fixedly connected at the bottom through the lower connecting seat 2. The fixed cooperation of the lower points and the upper activities can effectively achieve the purpose of small-scale limit when there is a slight adjustment in the whole buckling-restrained brace body 5. Generally speaking, before installation, the whole structure of this buckling-restrained brace can rely on the displacement adjustment unit installed at the bottom for bottom support of the whole structure. During support, it can achieve the overall support of the buckling-restrained brace structure under the combined action of the two displacement adjustment units, and cooperate with the hoisting equipment at the top to achieve displacement and adjustment in the horizontal direction. After moving in place, the displacement adjustment unit can be stored, and finally achieve stable support at the bottom of the whole structure; in addition, by adjusting the tensioning connecting piece at the corresponding position, the adjustment of the interval distance between the two ends of the horizontal strengthening component can be realized, and finally the adjustment of the lateral support effect on the buckling-restrained units at both ends can be achieved; the adjustment of the rotating handwheel 24 in cooperation with the adjusting screw 22 and the abutting ball 23 can achieve the pushing of the horizontal wheel shaft 20, so as to control the lifting and lowering of the horizontal wheel shaft 20 in the vertical direction. When the horizontal wheel shaft 20 is lifted, it can drive the moving wheel 21 at the end of the horizontal wheel shaft 20 to leave the ground and reach a state higher than the bottom of the lower connecting seat 2. The whole operation process is relatively fast and convenient.
