Description

Technical Field

[0001] The present invention relates to the technical field of wall reinforcement, and specifically to a building wall reinforcement device and a reinforcement method thereof. Background Technique

[0002] In a brick-concrete structure, the brick wall bears the load-bearing function, playing a role in support and earthquake resistance. However, over time and with the aging of the building, the brick wall may crack, deform, or have insufficient load-bearing capacity. To enhance the structural stability and load-bearing capacity of the building, it is necessary to reinforce and transform the wall. In the prior art for the reinforcement and transformation of brick-concrete structure walls, the commonly used method is to change the wall into a beam, transferring the load originally borne by the wall to the beam, thereby improving the load-bearing capacity of the wall; the wall-to-beam transformation can be achieved by adding a reinforced concrete beam or a steel beam above the wall. After determining the position of the cross beam, it is necessary to carry out demolition work on the wall surface. Before demolition, it is necessary to use a temporary support device to replace the support function of the original wall. The existing support device is generally a support rod, and multiple groups of support rods are arranged between the ground and the roof to complete the temporary support function.

[0003] However, when the existing building wall reinforcement device and its reinforcement method are in use, multiple groups of support rods are not convenient for synchronous support, and it is not convenient to adaptively adjust the support width according to the width of the wall, affecting the support efficiency and effect; there may be protrusions on the surface of the roof, making it impossible for the support to fit tightly with the roof, resulting in gaps or air pockets. This will reduce the effective contact area between the support and the roof, lower the load-bearing capacity of the support system, and prevent the full play of the support role, affecting the support effect; the surface of the roof is relatively smooth, and when the support rod is supporting, it is easy to slide on the roof due to external collisions, which will also affect the support effect.

[0004] Therefore, we propose a building wall reinforcement device and a reinforcement method thereof. Summary of the Invention

[0015] Preferably, a method for strengthening a building wall uses a building wall strengthening device as described above, and includes the following steps:

[0016] S1: When wall-to-beam modification is required, strengthening devices are arranged on both sides of the wall to support the roof. When supporting, first start the motor. The rotation of the motor drives the rotation of the wire winding wheel, so that the pulling rope can be wound up. At this time, the third moving block can be pulled to move towards the fixed block. At the same time, the first spring is compressed, and the first moving block is driven to move synchronously through the first guide rod. At the same time, when the first moving block moves, the second scraper can be driven to move synchronously along the side wall of the first scraper through the limiting plate and the connecting plate. When the first ball contacts the walls on both sides, stop the motor to facilitate adjusting the width of the support according to the width of the wall, which is not only more convenient and fast to use, but also has a better supporting effect;

[0017] S2: When the second scraper moves, the second moving plate can be driven to move along the side wall of the first moving plate through the guide rail and the slider, so that the ranges of the first pointed cone and the second pointed cone can also be applicable to the width of the wall;

[0018] S3: Drive the second piston to move downward through the second lifting module. At this time, the hydraulic oil in the hydraulic oil cylinder can be extruded, so that the hydraulic oil can enter each fixed pipe through the third connecting pipe, the second connecting pipe and the first connecting pipe, and under the action of the hydraulic pressure, the first piston can be pushed to move upward. When the first piston moves upward, the lifting plate can be driven to move upward through the support pipe and the moving rod, so that the first U-shaped plate and the first support plate are driven to move upward through the pressure control mechanism, and then the first scraper and the second scraper are driven to move upward through the second moving mechanism;

[0019] S4: When the second ball contacts the top of the roof, drive the first moving plate to move upward through the first lifting module. At the same time, drive the second moving plate and the second pointed cone to move upward through the guide rail and the first sleeve rod. At this time, the first pointed cone and the second pointed cone can abut against the roof. When the lifting plate continues to move upward, the third spring is gradually compressed. At this time, the first U-shaped plate and the first support plate can continue to move upward, and the distance between the third support plate and the fourth moving block gradually becomes smaller. When the first support plate continues to move upward, it can drive the triangular block to move synchronously through the L-shaped block, so that the upper inclined surface can abut against the side wall of the fifth moving block, thereby driving the first scraping plate and the second scraping plate to move synchronously through the second guide rod. At this time, the first pointed cone and the second pointed cone can scrape the roof to make it rough, increasing its friction force and making the support more stable and reliable. When the triangular block passes over the fifth moving block, the first scraping plate and the second scraping plate can move back under the action of the return spring. At this time, drive the first moving plate and the second moving plate to move downward through the first lifting module, and make the first pointed cone and the second pointed cone separate from the roof;

[0020] S5: After the first pointed cone and the second pointed cone finish scraping the roof, the first bristles and the second bristles can clean the roof, and the third bristles can clean the tops of the first support plate and the second support plate. At the same time, the first scraping plate and the second scraping plate can scrape and clean the protrusions on the roof, ensuring the effect of the contact surface between the first support plate and the second support plate and the roof, thereby improving the support effect;

[0021] S6: After the triangular block passes over the fifth moving block, when the first support plate moves upward and abuts against the roof, the second support plate also abuts against the roof. When the lifting plate continues to move upward, the second spring is gradually compressed. At this time, the distance change between the lifting plate and the first U-shaped plate can be detected by the distance sensor, so as to determine the compression amount of the second spring, and further determine the extrusion force between the first support plate and the slot and the roof, making the support effect better. And when carrying out the support, under the action of the hydraulic pressure, it can push a plurality of moving rods to move upward synchronously, with better synchronism and making the support effect better;

[0022] S7: After the support reinforcement is completed, demolish the part of the wall that needs to be renovated, change it into the form of a beam, and pour a concrete beam on site.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] The present invention is provided with a scratching mechanism, a first moving mechanism, a cleaning mechanism, etc., which facilitate adjusting the width of the support according to the width of the wall and facilitating synchronous support.

The side wall of the first connecting tube 911 is fixedly connected with a second connecting tube 912. A third connecting tube 913 is fixedly connected between the hydraulic oil cylinder 907 and the second connecting tube 912. By driving the second piston 910 to move downward through the second lifting module 909, at this time, the hydraulic oil in the hydraulic oil cylinder 907 can be squeezed, so that the hydraulic oil can enter each fixed tube 901 through the third connecting tube 913, the second connecting tube 912 and the first connecting tube 911, and under the action of the hydraulic pressure, the first piston 902 can be pushed upward. When the first piston 902 moves upward, the lifting plate 10 can be driven to move upward through the support tube 903 and the moving rod 904.

[0045] A method for strengthening a building wall uses a building wall strengthening device as described above and includes the following steps:

[0046] S1: When wall modification to beam is required, strengthening devices are arranged on both sides of the wall to support the roof. During the support, first start the motor 805. The rotation of the motor 805 drives the rotation of the wire winding wheel 806, thereby enabling the draw rope 807 to be wound up. At this time, the third moving block 802 can be pulled to move towards the fixed block 804. At the same time, the first spring 803 is compressed, and the first moving block 15 is driven to move synchronously through the first guide rod 801. Meanwhile, when the first moving block 15 moves, the second scraper 19 can be driven to move synchronously along the side wall of the first scraper 18 through the limiting plate 503 and the connecting plate 502. When the first ball 16 contacts the walls on both sides, stop the motor 805, which is convenient for adjusting the support width according to the width of the wall, making it not only more convenient and fast to use, but also having a better support effect;

[0047] S2: When the second scraper 19 moves, the second moving plate 205 can be driven to move along the side wall of the first moving plate 202 through the guide rail 207 and the slider 208, so that the ranges of the first pointed cone 204 and the second pointed cone 206 can also be adapted to the width of the wall;

[0048] S3: Drive the second piston 910 to move downward through the second lifting module 909. At this time, the hydraulic oil in the hydraulic oil cylinder 907 can be extruded, so that the hydraulic oil can enter each fixed pipe 901 through the third connecting pipe 913, the second connecting pipe 912 and the first connecting pipe 911, and can push the first piston 902 to move upward under the action of hydraulic pressure. When the first piston 902 moves upward, it can drive the lifting plate 10 to move upward through the support pipe 903 and the moving rod 904, thereby driving the first U-shaped plate 11 and the first support plate 12 to move upward through the pressure control mechanism, and then driving the first scraping plate 18 and the second scraping plate 19 to move upward through the second moving mechanism;

[0049] S4: When the second ball 403 contacts the top of the roof, drive the first moving plate 202 to move upward through the first lifting module 201. At the same time, drive the second moving plate 205 and the second sharp cone 206 to move upward through the guide rail 207 and the first sleeve rod 210. At this time, the first sharp cone 204 and the second sharp cone 206 can abut against the roof. When the lifting plate 10 continues to move upward, the third spring 703 is gradually compressed. At this time, the first U-shaped plate 11 and the first support plate 12 can continue to move upward, and the distance between the third support plate 701 and the fourth moving block 17 gradually becomes smaller. When the first support plate 12 continues to move upward, it can drive the triangular block 708 to move synchronously through the L-shaped block 707, so that the upper inclined surface 709 can abut against the side wall of the fifth moving block 706, thereby driving the first scraping plate 18 and the second scraping plate 19 to move synchronously through the second guide rod 704. At this time, the first sharp cone 204 and the second sharp cone 206 can scrape the roof to make it rough and increase its friction, making the support more stable and reliable. When the triangular block 708 passes over the fifth moving block 706, the first scraping plate 18 and the second scraping plate 19 can move back under the action of the return spring 705. At this time, drive the first moving plate 202 and the second moving plate 205 to move downward through the first lifting module 201, and make the first sharp cone 204 and the second sharp cone 206 disengage from the roof;

[0050] S5: After the first sharp cone 204 and the second sharp cone 206 finish scraping the roof, the first brush hair 302 and the second brush hair 303 can clean the roof, and the third brush hair 304 can clean the tops of the first support plate 12 and the second support plate 14. At the same time, the first scraping plate 18 and the second scraping plate 19 can scrape and clean the protrusions on the roof to ensure the effect of the contact surface between the first support plate 12 and the second support plate 14 and the roof, thereby improving the support effect;

[0051] S6: After the triangular block 708 passes over the fifth moving block 706, when the first support plate 12 moves upward and abuts against the roof, the second support plate 14 also abuts against the roof. When the lifting plate 10 continues to move upward, the second spring 603 is gradually compressed. At this time, the distance sensor 604 can detect the distance change between the lifting plate 10 and the first U-shaped plate 11, so as to determine the compression amount of the second spring 603, and further determine the extrusion force between the first support plate 12 and the slot 13 and the roof, making the support effect better. Moreover, when performing the support, under the action of the hydraulic pressure, multiple moving rods 904 can be pushed to move upward synchronously, with better synchronism and a better support effect.

[0052] S7: After the support reinforcement is completed, the part of the wall to be renovated is demolished and changed into the form of a beam, and a concrete beam is cast on site.
