Description

Technical Field

[0001] The present invention relates to the field of building construction, and in particular to a device and method for repairing and reinforcing a concrete structure building. Background Art

[0002] In the reinforcement of concrete structures, the implanted steel bars may be at a certain angle to the concrete structure as needed. This reinforcement method is called oblique embedding of steel bars, which means that the steel bars are implanted into the concrete at a certain angle to improve the overall strength and stability of the building. Therefore, the holes to be drilled must have a corresponding angle with the concrete structure. However, when drilling holes through manually controlled drilling rigs, it is difficult to ensure that the drilled holes meet the needs, resulting in the need to repair the damaged concrete structure, thereby increasing construction costs.

[0003] For example, the Chinese invention patent (application number: CN115229994B) discloses a "concrete structure building repair and reinforcement construction device and method". Its specification discloses that some concrete structures need to implant steel bars inside the original concrete structure during the later repair and reinforcement process to use the steel bars to enhance the connection strength between the new and old concretes. Before implanting the steel bars, a drill is required to drill holes in the original concrete structure. Although the drill bit can bring out most of the debris in the hole when drilling, there will still be a small amount of fine debris left in the hole. The remaining debris needs to be blown out with an air pipe later. This undoubtedly adds an extra construction process, especially for some concrete structure reinforcement projects that require a large number of steel bars to be implanted, which will seriously affect the construction efficiency; and the debris generated by drilling will be scattered on the ground or float in the air, thereby causing environmental pollution. Many concrete structure reinforcement projects are carried out after the decoration is completed or during the decoration process, which can easily cause the decoration to be contaminated, and the later cleaning is very troublesome and increases the construction cost. The above patents can prove the existing defects.

[0004] Therefore, we have made improvements to this and proposed a concrete structure building repair and reinforcement construction device and method. Summary of the invention

[0024] Beneficial effects of the present invention:

[0025] In the scheme of this application:

[0026] 1. In order to solve the problem that it is difficult to ensure that the required drilling hole matches the inclination angle of the concrete structure by manually controlling the drilling rig, the present application uses a fixed assembly to drive the gear plate to rotate by using the drill bit, thereby driving the strong magnetic ring to drive the moving rod to rotate and displace inside the sliding rod, and then form a snap connection with the spiral protrusions set inside the support rod, so that multiple support rods are fixed inside the sliding rod, and the inclination angle of the drill bit is fixed while the abutment plate and the concrete structure are kept in contact, so as to achieve drilling of holes and grooves that meet the requirements;

[0027] 2.

At the same time, the inside of the drill hole can be cleaned through the blowing hole opened at the end of the drill bit. The axial flow roller is used to drive the first auger to rotate, and the dust and debris collected in the assembly cavity are sent to the dust collection box, thereby collecting the dust and debris generated by the drilling and preventing environmental pollution.

[0028] 3. The protective component that is set up can use the sliding ring to move back and forth on the outer wall of the drill bit, and can abut against multiple Z-shaped rings at the same time, so as to squeeze and crush larger debris to prevent larger debris from clogging the dust guide hole. At the same time, it can block particularly large debris to prevent particularly large debris from entering and not being crushed in time, affecting the normal rotation of the drill bit driven by the motor and increasing the load.

[0051] The concrete structure building repair and reinforcement construction device provided by the present invention is to solve the problem that when the concrete structure is embedded with steel bars at an angle, the drilled holes need to have a corresponding angle with the concrete structure. However, it is difficult to ensure that the drilled holes meet the requirements when drilling with a manually controlled drill rig, resulting in the need to repair the damaged concrete structure, thereby increasing the construction cost. The present application sets a fixing component 2 to enable the support rod 204 to move toward the inside of the slide rod 201, and the abutment plate 207 and the ball protrusion 205 fixedly installed at the end of the support rod 204 are of a snap-fit ​​design, so that the abutment plate 207 can be tilted arbitrarily at the ends of multiple slide rods 201, and the angle between the drill bit 104 and the concrete structure is manually controlled, and the strong magnetic ring 2 is driven by the driving component 5. 03 rotates, through the strong magnetic attraction between the strong magnetic ring 203 and the moving rod 202, the rotation of the strong magnetic ring 203 changes the direction of the magnetic force, thereby driving the moving rod 202 to rotate inside the sliding rod 201.

One end of the plurality of support rods 204 is fixedly mounted with a ball protrusion 205, and the other end of the plurality of support rods 204 is fixedly mounted with a magnetic flange 213 and is located inside the slide rod 201. The magnetic flange 213 and the end of the slide rod 201 are designed for magnetic attraction. The outer walls of the plurality of ball protrusions 205 are clamped with abutment plates 207. The outer walls of the plurality of slide rods 201 are rotatably mounted with strong magnetic collars 203 and are located inside the housing 1. The strong magnetic collars 203 and the moving rod 202 are designed for strong magnetic attraction.

[0057] A driving assembly 5 for driving the fixing assembly 2 to work is arranged inside the housing 1;

[0059] The interior of the support rod 204, the ball protrusion 205 and the abutment plate 207 are all hollow in design and connected. A piston plate 208 is piston-slidably installed inside the support rod 204. A first return spring 206 is fixedly installed between the outer wall of the piston plate 208 and the inner wall of the ball protrusion 205. The outer wall array of the abutment plate 207 is provided with a plurality of hole grooves 209 and is connected to the interior. Conical blocks 210 are slidably installed in the plurality of hole grooves 209. A tension spring 211 is fixedly installed between the outer wall of the conical block 210 and the inner wall of the hole groove 209.

[0060] In order to solve the problem that when the reinforcement is obliquely inserted into the concrete structure, the hole groove to be drilled must have a corresponding angle with the concrete structure, but it is difficult to ensure that the drilled hole groove meets the requirements when drilling with a manually controlled drill rig, resulting in damage to the concrete structure and the need to repair it, thereby increasing the construction cost, the present application sets a fixing component 2 to enable the support rod 204 to move toward the inside of the slide rod 201, and the abutment plate 207 and the ball protrusion 205 fixedly installed at the end of the support rod 204 are of a snap-fit ​​design, so that the abutment plate 207 can be arbitrarily tilted at the ends of multiple slide rods 201, and the angle between the drill bit 104 and the concrete structure is manually controlled, and the strong magnetic ring 203 is driven to rotate by the driving component 5. The ring 203 and the moving rod 202 are strongly magnetically attracted, and the rotation of the strong magnetic ring 203 changes the direction of the magnetic force, thereby driving the moving rod 202 to rotate inside the slide rod 201. Since the moving rod 202 and the inside of the slide rod 201 are designed to be threaded, the moving rod 202 is displaced to one side of the support rod 204, and is clamped with the spiral protrusion 214 set inside the moving rod 202, so that multiple support rods 204 are fixed, and then the abutment plate 207 is fitted with the concrete structure and the angle with the drill bit 104 is fixed.

[0075] In order to solve the problem of large amounts of dust and debris generated during the drilling process polluting the environment, the present application sets a cleaning component 4 to use a servo motor 501 to drive the drill bit 104 to perform drilling, and at the same time drives the axial flow roller 413 to rotate, thereby driving the multiple axial flow blades 401 set inside the axial flow roller 413 to rotate, and seals one side of the drill bit 104 through the bellows 403, and the multiple dust guide holes 402 arranged in an array on the gear plate 502 can suck the dust and debris generated by the drilling of the drill bit 104 into the assembly cavity 105, and the multiple air guide holes 411 and the drill bit 104 opened on the outer wall of the drill bit 104 in the assembly cavity 105. The multiple blowing holes 412 opened at the end can deliver the circumferential wind generated by the axial flow blades 401 to the end of the drill bit 104, blow and wash the inside of the drill hole, and improve the cleanliness of the inside of the drill hole. At the same time, under the rotation of the drill bit 104, the meshing design of the fixed tooth surface 408 and the small gear ring 409 set in the shell 1 can drive the second auger 410 rotatably installed inside the air guide hole 411 to rotate, so that the dust and debris inside the air guide hole 411 can be blocked and output to the assembly chamber 105, preventing the dust and debris from entering the drill bit 104 and entering the inside of the drill hole again through the blowing holes 412, further improving the cleanliness.

[0076] Under the rotation of the axial flow roller 413, the meshing design of the face gear 405 and the large gear ring 404 can drive the first auger 406 to rotate, so that the dust and debris collected in the assembly cavity 105 can be transported to the bottom of the second grip 102, and then enter the dust box 414. Through the semi-arc card slot 416 and the vertical slot 417 opened in the dust cover 407, the two card blocks 415 symmetrically installed on the outer wall of the dust box 414 can make the dust cover 407 form a card connection with the dust box 414. At the same time, through the vertical slot 417, when pressure is applied to the dust box 414, it can move upward, indicating that the dust and debris collected inside is not full. When the dust box 414 cannot move upward when pressure is applied, it is necessary to disassemble the dust box 414 and process the dust and debris collected inside. Before 02 enters the assembly cavity 105, the protective component 3 uses the reciprocating screw groove 301 opened on the outer wall of the drill bit 104 through the sliding ring 302 and the reciprocating screw groove 301, so that the sliding ring 302 can be driven to move back and forth on the outer wall of the drill bit 104, and multiple Z-shaped rings 303 are set, and the second reset spring 304 is used to make multiple Z-shaped rings 303 fixedly connected in sequence from small to large. When the sliding ring 302 moves toward the gear plate 502, the multiple Z-shaped rings 303 and the sliding ring 302 can abut against each other to form an integral disc, so that larger debris can be squeezed and crushed to prevent larger debris from clogging the dust guide hole 402. At the same time, when multiple Z-shaped rings 303 are arranged in sequence, it can prevent particularly large debris from entering and not being crushed in time, affecting the normal rotation of the drill bit 104 driven by the servo motor 501, and increasing the load of the servo motor 501.

[0077] The use process of the concrete structure building repair and reinforcement construction device and method provided by the present invention is as follows:

[0078] First, the drill bit 104 is manually aligned with the drilling position, and the inclination angle of the drill bit 104 and the concrete structure is adjusted to ensure that the abutment plate 207 is in contact with the concrete structure, so as to press the motor switch 103 to start the servo motor 501 to drive the drill bit 104 to rotate, thereby driving the gear plate 502 to rotate, and the gear plate 502 is engaged with the tooth groove 503 provided on the outer wall of the strong magnetic ring 203, thereby driving and then driving the strong magnetic ring 203 to rotate, and utilizing the magnetic attraction of the strong magnetic ring 203 and the moving rod 202 and the threaded connection design of the moving rod 202 and the inner part of the sliding rod 201, so as to drive the moving rod 202 to move to one side of the support rod 204, and under the rotation displacement of the moving rod 202, it will form a card connection with the spiral protrusion 214 provided inside the support rod 204, so that multiple support rods 204 can be connected. The support rod 204 is fixed inside the sliding rod 201, so that the angle of the abutment plate 207 is fixed, so that the angle between the drill bit 104 and the concrete structure can be fixed, so as to ensure that the drilled hole groove meets the requirements. When the moving rod 202 is fixed to the support rod 204, the moving rod 202 can form an abutment with the piston plate 208 installed in a piston-like sliding manner inside the support rod 204, and can drive the piston plate 208 to move, so that the internal pressure of the abutment plate 207 can be increased, so that the conical block 210 slidably installed in the multiple hole grooves 209 opened on the outer wall of the abutment plate 207 can be displaced outwards and form an abutment with the concrete structure, so that the contact between the abutment plate 207 and the concrete structure can be stable, and the drill bit 104 and the drilling position can be prevented from being offset due to vibration during the drilling process.

[0079] The servo motor 501 drives the drill bit 104 to drill holes, and at the same time drives the axial flow roller 413 to rotate, thereby driving the multiple axial flow blades 401 arranged inside the axial flow roller 413 to rotate, and the bellows 403 seals one side of the drill bit 104, and the multiple dust guide holes 402 arranged in an array on the gear plate 502 can suck the dust and debris generated by the drill bit 104 drilling into the assembly chamber 105, and the multiple air guide holes 411 arranged on the outer wall of the drill bit 104 in the assembly chamber 105 and the multiple blowing holes 412 arranged at the end of the drill bit 104 can suck the axial flow blades The circumferential wind generated by 401 is delivered to the end of the drill bit 104 to purge the inside of the drill hole, thereby improving the cleanliness of the inside of the drill hole. At the same time, under the rotation of the drill bit 104, the meshing design of the fixed tooth surface 408 and the small tooth ring 409 provided in the housing 1 can drive the second auger 410 rotatably installed inside the air guide hole 411 to rotate, thereby blocking the dust and debris inside the air guide hole 411 and outputting it into the assembly chamber 105, preventing the dust and debris from entering the drill bit 104 and entering the inside of the drill hole again through the blowing hole 412, thereby further improving the cleanliness.

[0080] Under the rotation of the axial flow roller 413, the meshing design of the face gear 405 and the large gear ring 404 can drive the first auger 406 to rotate, so that the dust and debris collected in the assembly cavity 105 can be transported to the bottom of the second grip 102, and then enter the dust box 414. Through the semi-arc card slot 416 and the vertical slot 417 opened in the dust cover 407, the two card blocks 415 symmetrically installed on the outer wall of the dust box 414 can make the dust cover 407 form a card connection with the dust box 414. At the same time, through the vertical slot 417, when pressure is applied to the dust box 414, it can move upward, indicating that the dust and debris collected inside is not full. When the dust box 414 cannot move upward when pressure is applied, it is necessary to disassemble the dust box 414 and process the dust and debris collected inside. Before 02 enters the assembly cavity 105, the protective component 3 uses the reciprocating screw groove 301 opened on the outer wall of the drill bit 104 through the sliding ring 302 and the reciprocating screw groove 301, so that the sliding ring 302 can be driven to move back and forth on the outer wall of the drill bit 104, and multiple Z-shaped rings 303 are set, and the second reset spring 304 is used to make multiple Z-shaped rings 303 fixedly connected in sequence from small to large. When the sliding ring 302 moves toward the gear plate 502, the multiple Z-shaped rings 303 and the sliding ring 302 can abut against each other to form an integral disc, so that larger debris can be squeezed and crushed to prevent larger debris from clogging the dust guide hole 402. At the same time, when multiple Z-shaped rings 303 are arranged in sequence, it can prevent particularly large debris from entering and not being crushed in time, affecting the normal rotation of the drill bit 104 driven by the servo motor 501, and increasing the load of the servo motor 501.
