Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1 - Figure 7 , the utility model provides a technical solution:

[0027] Example 1:

[0028] A wall crack repair and reinforcement steel structure includes a wall 1, a reinforcement steel structure 2 is provided on one side of the wall 1, connecting steel plates 3 are fixedly connected to both sides of the reinforcement steel structure 2, two steel sleeves 4 are sleeved on the surface of the connecting steel plates 3, and a positioning frame 5 is fixedly connected to the sides of the two steel sleeves 4 facing away from each other, a high-strength screw 6 is threadedly connected to one side of the positioning frame 5, a threaded hole 7 for use with the high-strength screw 6 is opened on one side of the positioning frame 5, one end of the high-strength screw 6 passes through the interior of the wall 1, a width adjustment mechanism is provided inside the reinforcement steel structure 2, and a height adjustment mechanism is provided on one side of the steel sleeve 4;

[0029] The width adjustment mechanism includes a twisting rod 8 arranged on one side of the reinforced steel structure 2, one end of the twisting rod 8 passes through the interior of the reinforced steel structure 2 and is fixedly connected to the first bevel gear 9, both sides of the first bevel gear 9 are meshed with the second bevel gear 10, and the two second bevel gears 10 are fixedly connected to the sides away from each other with a screw rod 11, and the surface of the screw rod 11 is transmission-connected to the telescopic block 12, one end of the telescopic block 12 passes through one side of the reinforced steel structure 2 and is fixedly connected to one side of the connecting steel plate 3.

[0030] In this embodiment, it is taken into account that the existing reinforced steel structure 2 is very limited in use and cannot adjust the width of the reinforced steel structure 2 according to the width of the crack in the wall 1, which will affect the stability of the subsequent reinforcement. Therefore, by setting a width adjustment mechanism, it is possible to observe the width of the crack and then rotate the twisting block 23. The twisting block 23 drives the twisting rod 8 and the bevel gear to rotate around the first bearing, and the first bevel gear 9 drives the second bevel gear 10 and the screw rod 11 to rotate around the second bearing. When the screw rod 11 rotates, it transmits the telescopic block 12, so that the two telescopic blocks 12 move to the side away from each other along the sliding block 21 and the sliding groove 22, and at the same time drives the connecting steel plate 3, the steel sleeve 4 and the positioning frame 5 to move. After reaching the appropriate position, the positioning frame 5 is fixed to the wall 1 by the high-strength screws 6, and the wall 1 can be reinforced, thereby improving the stability of the reinforcement;

[0031] The invention solves the problem that the existing reinforcement steel structure 2 is very limited in use and the width of the reinforcement steel structure 2 cannot be adjusted according to the width of the crack in the wall 1, which will affect the stability of subsequent reinforcement.

[0032] One side of the first bevel gear 9 is rotatably connected to the inner wall of the reinforced steel structure 2 through a first bearing. The inner wall of the reinforced steel structure 2 is fixedly connected to two support frames 20. The inner wall of the support frame 20 is rotatably connected to the surface of the screw rod 11 through a second bearing.

[0033] In this embodiment, by providing the first bearing, the support frame 20 and the second bearing, the first bevel gear 9 and the second bevel gear 10 can be supported so that they always remain in a meshing state, and the smoothness of their rotation process can also be improved.

[0034] The top and bottom of the telescopic block 12 are fixedly connected to the sliding block 21 , and the inner wall of the reinforced steel structure 2 is provided with a sliding groove 22 used in conjunction with the sliding block 21 .

[0035] In this embodiment, by providing the sliding block 21 and the sliding groove 22, when the screw rod 11 rotates to transmit the telescopic block 12, the telescopic block 12 is restricted to move only along the track of the sliding block 21 and the sliding groove 22, while improving its stability during movement.

[0036] One end of the twisting rod 8 is fixedly connected to a twisting block 23 , and four twisting grooves 24 are formed on the surface of the twisting block 23 .

[0037] In this embodiment, the twisting block 23 and the twisting groove 24 are provided to provide a gripping point for the user, so that the user can easily rotate the twisting block 23 and the first bevel gear 9 .

[0038] Example 2:

[0039] On the basis of Example 1, this embodiment takes into account that the height of the crack in the wall 1 may also be different. If the distance between the high-strength screws 6 on the upper and lower positioning frames 5 is not matched, it will also affect the stability of the reinforcement. The height adjustment mechanism in this application includes a shell 13 fixedly connected to one side of the steel sleeve 4, and a moving block 14 is provided inside the shell 13. One side of the moving block 14 is fixedly connected to a positioning rod 15, and one end of the positioning rod 15 passes through the interior of the steel sleeve 4. A positioning hole 16 for use with the positioning rod 15 is opened on one side of the connecting steel plate 3. The end of the moving block 14 away from the positioning rod 15 is fixedly connected to a traction rod 17, and one end of the traction rod 17 passes through one side of the shell 13 and is fixedly connected to a traction block 18.

[0040] In this embodiment, it is taken into account that the height of the cracks in the wall 1 may also be different. If the distance between the high-strength screws 6 on the upper and lower positioning frames 5 is not matched, the stability of the reinforcement will be affected. Therefore, by providing a height adjustment mechanism, the traction block 18 can be pulled, and the traction block 18 will drive the traction rod 17, the moving block 14 and the positioning rod 15 to move, so that the positioning rod 15 leaves the inside of the positioning hole 16, and the restriction of the steel sleeve 4, the positioning frame 5 and the high-strength screw 6 is released. After that, the height of the steel plate 3 can be adjusted along the trajectory of the connection. After reaching the appropriate position, the traction block 18 is released, and the elastic force generated by the spring 19 will drive the moving block 14 and the positioning rod 15 to move, so that the positioning rod 15 enters the corresponding positioning hole 16, and the distance between the upper and lower high-strength screws 6 is adjusted.

[0041] The problem is solved that the height of the crack in the wall 1 may also be different. If the distance between the high-strength screws 6 on the upper and lower positioning frames 5 is not suitable, the stability of the reinforcement will also be affected.

[0042] A spring 19 is sleeved on the surface of the traction rod 17 . One end of the spring 19 is fixedly connected to one side of the moving block 14 , and the other end of the spring 19 is fixedly connected to the inner wall of the housing 13 .

[0043] In this embodiment, by providing the spring 19 , when the traction block 18 is released, the elastic force generated by the spring 19 can drive the moving block 14 and the positioning rod 15 to move, thereby playing a role of resetting.

[0044] There are a number of positioning holes 16 , which are evenly distributed on one side of the connecting steel plate 3 .

[0045] In this embodiment, by providing a plurality of positioning holes 16 , after the height of the steel sleeve 4 is adjusted, the positioning rod 15 can enter the corresponding positioning hole 16 to complete the rapid positioning of the steel sleeve 4 .

[0046] Working principle: After observing the width of the crack, the user rotates the twisting block 23, which drives the twisting rod 8 and the bevel gear to rotate around the first bearing. The first bevel gear 9 drives the second bevel gear 10 and the screw rod 11 to rotate around the second bearing. When the screw rod 11 rotates, it drives the telescopic block 12, so that the two telescopic blocks 12 move away from each other along the sliding block 21 and the sliding groove 22, and at the same time drives the connecting steel plate 3, the steel sleeve 4 and the positioning frame 5 to move. After reaching the appropriate position, the positioning frame 5 is fixed to the wall 1 by the high-strength screws 6, so that the wall 1 can be reinforced, thereby improving the stability of the reinforcement.

[0047] Taking into account that the height of the crack in the wall 1 may also be different, if the distance between the high-strength screws 6 on the upper and lower positioning frames 5 is not matched, it will also affect the stability of the reinforcement. Therefore, by pulling the traction block 18, the traction block 18 will drive the traction rod 17, the moving block 14 and the positioning rod 15 to move, so that the positioning rod 15 leaves the inside of the positioning hole 16, and the restriction on the steel sleeve 4, the positioning frame 5 and the high-strength screw 6 is released. After that, the height can be adjusted along the trajectory of the connecting steel plate 3. After reaching the appropriate position, the traction block 18 is released, and the elastic force generated by the spring 19 will drive the moving block 14 and the positioning rod 15 to move, so that the positioning rod 15 enters the corresponding positioning hole 16, completing the adjustment of the distance between the upper and lower high-strength screws 6.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
