After completion, rotate the threaded rod to drive the slider A to move horizontally, and make the slider B, the connecting rod and the moving block move downward synchronously, drive the four sets of sliding rods and the protrusions to move outward synchronously, and insert the protrusions into the foundation, increase the contact area and friction between the building structure and the foundation, and complete the installation of the reinforcement mechanism;

By moving the fixing block to adjust the inclination angle of the supporting plate, the supporting plate can always fit with the outer wall of the building beam, and the supporting rod can provide auxiliary support effect, thereby improving the stability between the building beam and the pillar, thereby avoiding the problem that the building beam may shake due to lack of sufficient support, which affects the overall building structure.

[0022] The present invention provides a buffer spring and a rubber pad, etc., so that when the pillar is subjected to a large impact or earthquake, the buffer mechanism as a whole can provide a better buffering effect for the pillar, reduce the rigid impact of the impact on the pillar, and thus improve the stability of the pillar to avoid affecting the overall building structure;

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 4As shown, the present invention provides a building reinforcement engineering structure, including a pillar 1 and a building beam 2, the bottom outer wall of the pillar 1 is provided with a buffer mechanism 4, and the outer wall of the pillar 1 is provided with a support mechanism 3; the support mechanism 3 includes a mounting plate 301, the inner wall of the mounting plate 301 is slidably connected with a trapezoidal block 304, the inner wall of the mounting plate 301 is slidably connected with a bent rod 305, the inner wall of the mounting plate 301 is elastically connected with a wedge block 307 through a connecting spring 306, the inner wall of the mounting plate 301 is clamped with a connecting plate 302, the outer wall of the connecting plate 302 is provided with a clamping groove 308, the outer wall of the connecting plate 302 is provided with a groove 309, the outer wall of the connecting plate 302 is hinged with a support plate 303, the outer wall of the support plate 303 is hinged with a fixed block 311 through a support rod 310, and the inner wall of the fixed block 311 is elastically connected with an insert block 313 through a reset spring 312.

[0034] The above scheme is adopted: the pillar 1 and the building beam 2 are common building structures, and the support mechanism 3 can provide a supporting effect between the building beam 2 and the pillar 1, so that the connection between the two is more stable; the mounting plate 301 can be fixed to the outer wall of the pillar 1 by bolts or welding, and a set of mounting plates 301 can be installed on the outer wall of each side of the pillar 1, and the support mechanism 3 can be flexibly installed according to the position between the building beam 2 and the pillar 1; the bottom outer wall of the trapezoidal block 304 is flush with the bottom outer wall of the mounting plate 301, and the operator can push the trapezoidal block 304 upward; under normal conditions, the bent rod 305 is always in contact with the short side inclined surface of the trapezoidal block 304. When the trapezoidal block 304 is forced to move upward, the inclined surfaces on both sides thereof will squeeze the bent rod 305, causing it to move along the inclined surface to the long side of the trapezoidal block 304, and at the same time move horizontally to both sides, driving the wedge block 307 to slide on the inner wall of the mounting plate 301, so that the wedge block 307 can be out of contact with the slot 308.

[0035] like Figures 1 to 4 As shown, the mounting plate 301 is fixedly connected to the outer wall of the pillar 1, one end of the bent rod 305 is slidably connected to the outer wall of the trapezoidal block 304, the other end of the bent rod 305 is fixedly connected to the outer wall of the wedge block 307, and the two ends of the support rod 310 are hinged to the outer walls of the fixed block 311 and the support plate 303 respectively; one end of the connecting spring 306 is fixedly connected to the outer wall of the wedge block 307, the other end of the connecting spring 306 is fixedly connected to the inner wall of the mounting plate 301, the wedge block 307 is slidably connected to the inner wall of the mounting plate 301, and the wedge block 307 is engaged with the slot 308; one end of the return spring 312 is fixedly connected to the inner wall of the fixed block 311, the other end of the return spring 312 is fixedly connected to the outer wall of the plug block 313, the plug block 313 is slidably connected to the inner wall of the fixed block 311, and the plug block 313 is engaged with the groove 309.

[0036] The above scheme is adopted: under normal conditions, the connecting spring 306 keeps the wedge block 307 engaged in the slot 308 to ensure that the connecting plate 302 is fixed inside the mounting plate 301; and when the trapezoidal block 304 moves to disengage the wedge block 307 from the slot 308, the fixing of the connecting plate 302 can be released and removed; the support plate 303 can be turned over and contacted with the bottom end of the building beam 2, and the building beam 2 is supported by the support rod 310; the fixed block 311 on the outer wall of the support rod 310 is slidably connected to the outer wall of the connecting plate 302, and the plug block 313 in the fixed block 311 is engaged with the groove 309 to fix the position of the support rod 310, and a shift block is provided below the plug block 313. The shift block can be moved to the inner wall of the fixed block 311 by shifting the shift block, and the fixed block 311 can be moved up and down to adjust the angle between the support rod 310 and the support plate 303 by disengaging the contact with the groove 309; and Figure 2 As shown, part of the building beam 2 may be tilted on the pillar 1, and since the support plate 303 can rotate around the hinge point to be tilted and always in contact with the outer wall of the building beam 2, and then be clamped with different grooves 309 through the plug block 313, the support rod 310 and the support plate 303 can flexibly adapt to the force requirements of the building structure in different directions, thereby strengthening the support of the building beam 2.

[0037] like Figure 5 and Figure 6 As shown, the buffer mechanism 4 includes a fixed plate A401, the bottom outer wall of the fixed plate A401 is fixedly connected to the inner rod 403, the bottom outer wall of the inner rod 403 is fixedly connected to the rubber pad 404, the outer wall of the inner rod 403 is elastically connected to the sleeve rod 405 through a buffer spring 406, the bottom outer wall of the sleeve rod 405 is fixedly connected to the fixed plate B402, and the outer wall of the fixed plate B402 is provided with a reinforcement mechanism 5; the fixed plate A401 is fixedly connected to the bottom outer wall of the pillar 1, one end of the buffer spring 406 is fixedly connected to the outer wall of the sleeve rod 405, the other end of the buffer spring 406 is fixedly connected to the outer wall of the inner rod 403, and the inner rod 403 is slidably connected to the inner wall of the sleeve rod 405.

[0038] The above scheme is adopted: the fixing plate A401 can be fixed to the bottom end of the pillar 1 by welding or other means, and the buffer mechanism 4 is installed as a whole in the foundation, and the top of the fixing plate A401 is lower than the ground surface; when the pillar 1 is subjected to an earthquake or a large impact force, the buffer mechanism 4 can reduce the shaking amplitude of the pillar 1, reduce its rigid impact, and improve its stability to prevent it from tipping over; when subjected to vibration or impact, the pillar 1 will cause the inner rod 403 to slide relative to the sleeve rod 405, compressing the buffer spring 406, and the elastic deformation of the buffer spring 406 absorbs and dissipates energy, reducing the direct effect of the impact force on the pillar 1 and the entire building foundation; at the same time, the rubber pad 404 is in contact with multiple groups of buffer grooves on the inner wall of the sleeve rod 405, and will be continuously squeezed and deformed

[0039] like Figure 5 and Figure 7 As shown, the reinforcement mechanism 5 includes a fixed cone 501, the inner wall of the fixed cone 501 is threadedly connected with a threaded rod 502, the outer wall of the threaded rod 502 is rotatably connected with a slider A503, the outer wall of the slider A503 is slidably connected with a slider B504, the outer wall of the bottom end of the slider B504 is fixedly connected with a connecting rod 505, the outer wall of the connecting rod 505 is fixedly connected with a moving block 506, the outer wall of the moving block 506 is slidably connected with a sliding rod 507, and the outer wall of the sliding rod 507 is fixedly connected with a protrusion 508; the fixed cone 501 is plugged into the outer wall of the fixed plate B402, the sliders A503 and B504 are both slidably connected to the inner wall of the fixed cone 501, the connecting rod 505 is slidably connected to the inner wall of the fixed cone 501; the moving block 506 is slidably connected to the inner wall of the fixed cone 501, and the fixed cone 501 contacts the outer wall of the bottom end of the fixed plate A401.

[0040] The above scheme is adopted: the bottom of the fixed cone 501 is conical and can be inserted into the foundation to fix the fixed plate B402. The fixed plate A401 can be fixed on the fixed cone 501 by welding or bolts to provide stability for the overall structure; when the threaded rod 502 is rotated, the threaded rod 502 will move in the inner wall of the fixed cone 501. Since the slider A503 is rotatably connected to the threaded rod 502 and slidably connected to the inner wall of the fixed cone 501, the slider A503 can be moved laterally; the slider A503 and the slider B504 are both provided with inclined surfaces, and the inclined surfaces of the two are slidably connected, and the slider When A503 moves horizontally, it will drive the slider B504 to move up and down; when the slider B504 moves up and down, it will drive the connecting rod 505 and the moving block 506 to move synchronously. The moving block 506 is a frustum that is larger at the top and smaller at the bottom. When it moves, it will drive the four groups of sliding rods 507 on the outer wall to move along its outer wall. Since the sliding rods 507 are slidingly connected to the inner wall of the fixed cone 501, they can only move horizontally to the middle or outside, driving the protrusions 508 to move synchronously; the protrusions 508 can be inserted into the foundation to increase the contact area and friction, thereby further strengthening the stability of the connection between the building structure and the foundation.

[0041] The present application also proposes a construction method for a building reinforcement engineering structure, comprising the following steps:

[0042] S1. Place the fixing plate B402 in the deep pit dug in the foundation, insert the fixing cone 501 into the through groove of the fixing plate B402, and insert it downward into the foundation. After completion, rotate the threaded rod 502 to drive the slider A503 to move horizontally, and make the slider B504, the connecting rod 505 and the moving block 506 move downward synchronously, drive the four sets of sliding rods 507 and the protrusion 508 to move outward synchronously, and make the protrusion 508 insert into the foundation, increase the contact area and friction between the building structure and the foundation, and complete the installation of the reinforcement mechanism 5;

[0043] S2, fix the sleeve rod 405 on the fixing plate B402, and fix the fixing plate A401 on the top of the inner rod 403, completing the preliminary assembly of the buffer mechanism 4. At this time, the top of the fixing plate A401 is lower than the ground plane, and then fix the pillar 1 on the fixing plate A401, and fix the building beam 2 above the pillar 1;

[0044] S3. According to the relative position of the building beam 2 and the pillar 1, the mounting plate 301 is fixed at a suitable position on the outer wall of the pillar 1 to ensure that each group of support plates 303 can contact the building beam 2, and then the connecting plate 302 is installed in the mounting plate 301, and the connecting plate 302 is fixed by engaging the wedge block 307 with the card slot 308. Then, the block under the plug block 313 can be moved to make the plug block 313 disengage from the groove 309, and the fixing block 311 can be moved up and down to drive the support plate 303 to flip through the support rod 310. When the support plate 303 flips to contact the bottom end of the building beam 2, the block is released, and the plug block 313 is inserted into the corresponding groove 309 under the action of the reset spring 312 to fix the angle between the support rod 310 and the support plate 303, and the installation and adjustment of the support mechanism 3 are completed, so that it can play a stable supporting role for the building beam 2.

[0045] S4. When the building structure changes, the operator can push the trapezoidal block 304 upwards, and the trapezoidal block 304 causes the bent rod 305 to move laterally to both sides at the same time, driving the wedge block 307 to disengage from the slot 308, releasing the fixed state of the connecting plate 302 and removing it, and then fix another set of mounting plates 301 at other positions, and fix the connecting plate 302 on the set of mounting plates 301 for support. When the building beam 2 is inclined, the inclination angle of the support plate 303 can be adjusted so that it can always fit the outer wall of the building beam 2 to provide auxiliary support force, which is more flexible.

After completion, rotate the threaded rod (502) to drive the slider A (503) to move horizontally, and make the slider B (504), the connecting rod (505) and the moving block (506) move downward synchronously, drive the four sets of sliding rods (507) and the protrusions (508) to move outward synchronously, and make the protrusions (508) insert into the foundation, so as to increase the contact area and friction between the building structure and the foundation, and complete the installation of the reinforcement mechanism (5); S2, fix the sleeve rod (405) on the fixing plate B (402), and fix the fixing plate A (401) on the top of the inner rod (403), completing the preliminary assembly of the buffer mechanism (4). At this time, the top of the fixing plate A (401) is lower than the ground plane, and then fix the pillar (1) on the fixing plate A (401), and fix the building beam (2) above the pillar (1); S3. According to the relative position of the building beam (2) and the pillar (1), the mounting plate (301) is fixed at a suitable position on the outer wall of the pillar (1), ensuring that each set of support plates (303) can contact the building beam (2), and then the connecting plate (302) is installed in the mounting plate (301), and the connecting plate (302) is fixed by the wedge block (307) and the card groove (308), and then the block under the plug block (313) can be moved to make the plug block (313) and the groove (309) The fixing block (311) is disengaged from the contact, and the fixing block (311) is moved up and down, and the supporting plate (303) is driven to flip through the supporting rod (310). When the supporting plate (303) flips to contact the bottom end of the building beam (2), the shifting block is released, and the inserting block (313) is inserted into the corresponding groove (309) under the action of the return spring (312), and the angle between the supporting rod (310) and the supporting plate (303) is fixed, and the installation and adjustment of the supporting mechanism (3) is completed, so that it can play a stable supporting role for the building beam (2); S4. When the building structure changes, the operator can push the trapezoidal block (304) upwards, and the trapezoidal block (304) causes the bent rod (305) to move laterally to both sides at the same time, driving the wedge block (307) to disengage from the clamping groove (308), releasing the fixed state of the connecting plate (302) and removing it, and then fix another set of mounting plates (301) at other positions, and fix the connecting plate (302) on the set of mounting plates (301) for support. When the building beam (2) is inclined, the inclination angle of the supporting plate (303) can be adjusted so that it can always fit with the outer wall of the building beam (2) to provide auxiliary support force, which is more flexible.
