The crack sensor and the inclination sensor are electrically connected to the 4G module.

[0015] A connection method for a building structure reinforcement connection device includes the following steps: Step 1: When the floor beam needs to be strengthened, a crack sensor is fixedly installed at the front end of the crack in the floor beam, an inclination sensor is installed on the front side of the load-bearing wall, and an arch support mechanism is installed on both the front and rear sides of the floor beam. The steel bar structure inside the load-bearing wall is detected, and the positioning bolts are installed through the wall while avoiding the internal steel bars. The positioning bolts pass through both sides of the load-bearing wall and positioning plates are installed. A strengthening mechanism positioning seat is fixedly installed on one side of the positioning plate, and an upper fixing seat of the resistance type strengthening mechanism is fixedly installed on the other side of the positioning plate. A lower fixing seat of the resistance type strengthening mechanism is fixedly installed on the ground, and a resistance type strengthening mechanism is installed between the lower fixing seat and the upper fixing seat of the resistance type strengthening mechanism; Step 2: An arch support mechanism is installed between the two strengthening mechanism positioning seats. The arch support mechanism is connected to the strengthening mechanism positioning seat through a fixed end, and the angle between the strengthening mechanism positioning seat and the fixed end can change with the change of stress; Step 3: A support rod is connected to the front side of the load-bearing plate of the front arch support mechanism through a clamping mechanism, and a support rod is connected to the rear side of the load-bearing plate of the rear arch support mechanism through a clamping mechanism. When the clamping mechanism is connected to the load-bearing plate, the clamping mechanism is pushed towards the load-bearing plate, so that the locking end corresponds to the locking groove of the load-bearing plate. After the load-bearing plate enters the clamping mechanism, the locking end of the locking hook is pushed, so that the locking hook rotates towards the direction of the push block along the locking hook rotating shaft. When the locking end corresponds to the position of the locking groove of the load-bearing plate, the upper end of the locking hook is moved by the first slider provided with a compression spring on one side, and thus rotates towards the load-bearing plate, and then enters the inside of the locking groove of the load-bearing plate, thereby realizing the fixed locking of the clamping mechanism and the load-bearing plate. The first supporting plate is passed through the first supporting plate groove of the support rod and the second supporting plate groove of the locking plate. When it moves to a suitable position, the locking plate is lowered, and the limiting teeth of the locking plate are engaged with the tooth row, thereby realizing the limitation of the first supporting plate. At this time, the first supporting plate is in close connection with the floor beam through the connecting cushion plate. The force of the floor beam is transmitted to the arch support mechanism through multiple first supporting plates. Due to the curved surface shape of the arch support mechanism, the concentrated load is dispersed into a linear load along the arch ring, and the force flow is transmitted through the mutual extrusion between components, making its stress more uniform. The vertical load is decomposed into a vertical force and a horizontal thrust, both of which are transmitted to the load-bearing wall, which can reduce the bending moment and shear force at the arch crown and enhance the overall stability; Step 4: When the load-bearing wall needs to be strengthened, install an inclination sensor on the front side of the load-bearing wall, symmetrically install arched support mechanisms at the front and back below the load-bearing wall, detect the steel bar structure inside the load-bearing wall, avoid the internal steel bars and penetrate and install positioning bolts. The positioning bolts pass through both sides of the load-bearing wall and install positioning plates. Fix and install a reinforcement mechanism positioning seat on one side of the positioning plate, fix and install an upper fixed seat of the resistance reinforcement mechanism on the other side of the positioning plate, fix and install a lower fixed seat of the resistance reinforcement mechanism on the ground, install a resistance reinforcement mechanism between the lower fixed seat of the resistance reinforcement mechanism and the upper fixed seat of the resistance reinforcement mechanism, install an arched support mechanism between the two reinforcement mechanism positioning seats, and connect the arched support mechanism and the reinforcement mechanism positioning seat through a fixed end. The angle between the reinforcement mechanism positioning seat and the fixed end can change with the change of stress; Step 5: Connect a support rod through a clamping mechanism on the front side above the load-bearing plate of the arched support mechanism on the front side, and connect a support rod through a clamping mechanism on the rear side above the load-bearing plate of the arched support mechanism on the rear side. Pass the first supporting plate through the first supporting plate groove of the support rod and the second supporting plate groove of the locking plate, and engage the limiting teeth of the locking plate with the tooth row to realize the limit of the first supporting plate. At this time, the first supporting plate and the second supporting plate are attached to the load-bearing wall through a connecting cushion plate, and the force on the load-bearing wall is transmitted to the arched support mechanism through multiple first supporting plates, thereby providing stable support for the load-bearing wall; Step 6: When the load-bearing wall is subjected to the horizontal force of the arched support mechanism, the resistance reinforcement mechanism installed on the side of the load-bearing wall away from the arched support mechanism cancels each other out through the horizontal thrust of the resistance reinforcement mechanism, improves the stability of the load-bearing wall, enhances the seismic resistance of the load-bearing wall, optimizes the reinforcement structure system, can repair the existing damage of the building, delays the aging of materials, and enables the building to adapt to functional changes.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When the floor beam needs to be reinforced, an arch support mechanism is installed on the front and rear sides of the floor beam. A resistance reinforcement mechanism lower fixing seat is fixedly installed on the ground, and a resistance reinforcement mechanism is installed between the resistance reinforcement mechanism lower fixing seat and the resistance reinforcement mechanism upper fixing seat. An arch support mechanism is installed between the two reinforcement mechanism positioning seats. The arch support mechanism is connected to the reinforcement mechanism positioning seat through a fixed end. The angle between the reinforcement mechanism positioning seat and the fixed end can change with the change of stress. A support rod is connected to the front side of the load-bearing plate of the front arch support mechanism through a clamping mechanism, and a support rod is connected to the rear side of the load-bearing plate of the rear arch support mechanism through a clamping mechanism. When the clamping mechanism is connected to the load-bearing plate, the clamping mechanism is pushed towards the load-bearing plate to make the locking end correspond to the locking groove of the load-bearing plate. After the load-bearing plate enters the clamping mechanism, the locking end of the locking hook is pushed, so that the locking hook rotates towards the direction of the push block along the locking hook rotating shaft. When the locking end corresponds to the position of the locking groove of the load-bearing plate, the upper end of the locking hook is moved by the first slider provided with a compression spring on one side, so as to rotate towards the load-bearing plate, and then enter the inside of the load-bearing plate locking groove, thus realizing the fixed locking of the clamping mechanism and the load-bearing plate. The first supporting plate is passed through the first supporting plate groove of the support rod and the second supporting plate groove of the locking plate. When it moves to a suitable position, the locking plate is lowered, and the limit teeth of the locking plate are engaged with the tooth row, so as to realize the limitation of the first supporting plate. At this time, the first supporting plate and the floor beam are attached and connected through a connecting cushion plate. The force of the floor beam is transmitted to the arch support mechanism through multiple first supporting plates. Due to the curved surface shape of the arch support mechanism, the concentrated load is dispersed into a linear load along the arch ring, and the force flow is transmitted by the mutual extrusion between the components, making the force more uniform. The vertical load is decomposed into a vertical force and a horizontal thrust, both of which are transmitted to the load-bearing wall, which can reduce the bending moment and shear force at the arch crown and enhance the overall stability. When the load-bearing wall needs to be reinforced, arch support mechanisms are symmetrically installed on the front and rear sides below the load-bearing wall. A support rod is connected to the front side above the load-bearing plate of the front arch support mechanism through a clamping mechanism, and a support rod is connected to the rear side above the load-bearing plate of the rear arch support mechanism through a clamping mechanism. The first supporting plate is passed through the first supporting plate groove of the support rod and the first supporting plate groove of the locking plate. The limitation of the first supporting plate is realized through the engagement of the limit teeth of the locking plate with the tooth row. At this time, the first supporting plate and the second supporting plate are attached and connected to the load-bearing wall through a connecting cushion plate. The force of the load-bearing wall is transmitted to the arch support mechanism through multiple first supporting plates, thus providing stable support for the load-bearing wall, and solving the problems that the steel plate reinforcement connection device uses adhesives, and the quality of the steel bonding glue or improper construction is prone to cause air sensitivity problems; the carbon fiber reinforcement connection device needs to be additionally provided with a fireproof layer, and the cost is relatively high; the prestressed reinforcement connection device is technically complex, requires a professional team for construction, has a relatively high cost, and has poor seismic performance.

[0017] 2. When the resistance reinforcement mechanism installed on the side of the load-bearing wall away from the arched support mechanism is under the horizontal force of the arched support mechanism, the horizontal thrust of the resistance reinforcement mechanism is used to cancel each other out, improving the stability of the load-bearing wall, enhancing the seismic resistance of the load-bearing wall, optimizing the reinforcement structure system, repairing the existing damage of the building, delaying the aging of materials, and enabling the building to adapt to functional changes.

[0028] A connection method for a building structure reinforcement connection device includes the following steps: Step 1: When the floor beam 5 needs to be reinforced, a crack sensor 7 is fixedly installed at the front end of the crack gap of the floor beam 5, an inclination sensor 14 is installed on the front side of the load-bearing wall 3, arched support mechanisms 41 are installed on the front and back sides of the floor beam 5, the steel bar structure inside the load-bearing wall 3 is detected, and the positioning bolts are installed through avoiding the internal steel bars. The positioning bolts pass through both sides of the load-bearing wall 3 and install positioning plates 10. A reinforcement mechanism positioning seat 8 is fixedly installed on one side of the positioning plate 10, a fixed seat 11 on the resistance type reinforcement mechanism is fixedly installed on the other side of the positioning plate 10, a fixed seat 13 of the resistance type reinforcement mechanism is fixedly installed on the ground 1, and a resistance type reinforcement mechanism 12 is installed between the fixed seat 13 of the resistance type reinforcement mechanism and the fixed seat 11 of the resistance type reinforcement mechanism; Step 2: An arched support mechanism 41 is installed between the two reinforcement mechanism positioning seats 8, and the arched support mechanism 41 and the reinforcement mechanism positioning seat 8 are connected through a fixed end 9. The angle between the reinforcement mechanism positioning seat 8 and the fixed end 9 can change with the change of stress; Step 3: Connect the support rod 20 to the front side of the load-bearing plate 18 of the arch support mechanism 41 on the front side through the clamping mechanism 19, and connect the support rod 20 to the rear side of the load-bearing plate 18 of the arch support mechanism 41 on the rear side through the clamping mechanism 19. When the clamping mechanism 19 is connected to the load-bearing plate 18, push the clamping mechanism 19 towards the load-bearing plate 18 to align the locking end 33 with the locking groove 34 of the load-bearing plate. After the load-bearing plate 18 enters the clamping mechanism 19, it pushes the locking end 33 of the locking hook 27, causing the locking hook 27 to rotate towards the pushing block 24 along the locking hook rotating shaft 32. When the locking end 33 corresponds to the position of the locking groove 34 of the load-bearing plate, the upper end of the locking hook 27 is moved by the first slider 28 with a compression spring 31 arranged on one side, and thus rotates towards the load-bearing plate 18 and enters the interior of the locking groove 34 of the load-bearing plate, thereby realizing the fixed locking of the clamping mechanism 19 and the load-bearing plate 18. Pass the first support plate 15 through the first support plate groove 37 of the support rod and the second support plate groove 38 of the locking plate. When it moves to the appropriate position, lower the locking plate 35. The limiting teeth 39 of the locking plate 35 are engaged with the tooth row 36, thereby realizing the limitation of the first support plate 15. At this time, the first support plate 15 is attached and connected to the floor beam 5 through the connecting cushion plate 21. The force on the floor beam 5 is transmitted to the arch support mechanism 41 through multiple first support plates 15. Due to the curved surface shape of the arch support mechanism 41, the concentrated load is dispersed into the line load along the arch ring, and the force flow is transmitted through the mutual extrusion between components, making the force more uniform. The vertical load is decomposed into vertical force and horizontal thrust, both of which are transmitted to the load-bearing wall 3, which can reduce the bending moment and shear force at the arch crown and enhance the overall stability; Step 4: When the load-bearing wall 3 needs to be strengthened, install an inclination sensor 14 on the front side of the load-bearing wall 3, symmetrically install arch support mechanisms 41 at the front and rear below the load-bearing wall 3, detect the steel bar structure inside the load-bearing wall 3, and avoid installing positioning bolts through the internal steel bars. The positioning bolts pass through both sides of the load-bearing wall 3 and install positioning plates 10. The positioning plate 10 on one side is fixedly installed with a reinforcement mechanism positioning seat 8, the positioning plate 10 on the other side is fixedly installed with an upper fixed seat 11 of the resistance type reinforcement mechanism, the ground 1 is fixedly installed with a lower fixed seat 13 of the resistance type reinforcement mechanism, and a resistance type reinforcement mechanism 12 is installed between the lower fixed seat 13 of the resistance type reinforcement mechanism and the upper fixed seat 11 of the resistance type reinforcement mechanism. An arch support mechanism 41 is installed between the two reinforcement mechanism positioning seats 8, and the arch support mechanism 41 is connected to the reinforcement mechanism positioning seat 8 through a fixed end 9. The angle between the reinforcement mechanism positioning seat 8 and the fixed end 9 can change with the change of stress; Step Five: Connect the support rod 20 through the clamping mechanism 19 at the front side above the load-bearing plate 18 of the arch support mechanism 41 at the front side, and connect the support rod 20 through the clamping mechanism 19 at the rear side above the load-bearing plate 18 of the arch support mechanism 41 at the rear side. Pass the first supporting plate 15 through the first supporting plate groove 37 of the support rod and the second supporting plate groove 38 of the locking plate, and engage the limiting teeth 39 of the locking plate 35 with the tooth row 36, so as to realize the limitation of the first supporting plate 15. At this time, the first supporting plate 15 and the second supporting plate 16 are attached and connected to the load-bearing wall 3 through the connecting cushion plate 21, and the force of the load-bearing wall 3 is transmitted to the arch support mechanism 41 through multiple first supporting plates 15, thereby providing stable support for the load-bearing wall 3; Step Six: When the load-bearing wall 3 is subjected to the horizontal force of the arch support mechanism 41, the resistance type reinforcement mechanism 12 installed on the side of the load-bearing wall 3 away from the arch support mechanism 41 cancels each other out through the horizontal thrust of the resistance type reinforcement mechanism 12, improves the stability of the load-bearing wall 3, enhances the seismic resistance of the load-bearing wall 3, optimizes the reinforcement structure system, can repair the existing damage of the building, delays the aging of materials, and enables the building to adapt to functional changes.
