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.
[0024] Specific examples are given below.
[0025] like Figures 1 to 5As shown, a fully assembled concrete shear wall described in an embodiment of the present invention includes a base 1, a plurality of reserved steel bars 11 are fixedly connected to the top of the base 1; a shear wall body 12 is arranged on the top of the reserved steel bars 11; a plurality of slots 13 are opened at the bottom of the shear wall body 12; the slots 13 and the reserved steel bars 11 are correspondingly arranged and slidably matched; a plurality of guide rings 14 are fixedly connected to the bottom of the shear wall body 12; the guide rings 14 and the slots 13 are correspondingly arranged; a plurality of square plates 15 are fixedly connected to the side walls of the shear wall body 12; a threaded groove 16 is opened in the middle of the square plate 15; the threaded groove 16 and the slots 13 are in a communicating relationship; a plurality of bolts 17 are fixed to the side walls of the square plate 15; when working, the shear wall body 12 is first lifted by a machine and then moved above the base 1, and then the shear wall body 12 is lowered. When lowering, the shear wall body 12 will enter the slots 13 when the shear force When the wall body 12 is lowered and deviates from the position, it will contact the guide ring 14 and enter the slot 13 along the surface of the guide ring 14, so that the shear wall body 12 is automatically corrected when it deviates from the position. After the shear wall body 12 enters the slot 13, the pipe is extended to the slot 13 through the threaded groove 16 to pour mud into the slot 13 to fill the interior. After filling, the pipe is taken out and the bolt 17 is screwed into the threaded groove 16 to block the threaded groove 16 so that the mud is blocked and remains in the slot 13. By using the guide ring 14 to increase the guidance of the shear wall body 12, the accuracy of the reserved steel bar 11 entering the slot 13 can be increased. At the same time, when the shear wall body 12 is lowered, the guide ring 14 can also be used to increase the accuracy of the alignment of the reserved steel bar 11 and the slot 13. Then, the bolt 17 is used to seal the slot 13 after the pouring is completed to reduce the mud flowing out of the threaded groove 16.
[0026] like Figure 2 As shown, the inner wall of the slot 13 is fixed with a curved plate 2; the curved plate 2 is set in multiple ways on the slot 13; during operation, after the reserved steel bar 11 enters the slot 13, the end of the reserved steel bar 11 will contact the surface of the curved plate 2, thereby causing the reserved steel bar 11 to move. When the reserved steel bar 11 completely enters the slot 13, it will be fixed to the middle of the slot 13 by the curved plate 2, thereby fixing the position of the slot 13 in the middle of the slot 13 to leave space for the position of the mud. At the same time, because the surface of the curved plate 2 is porous, the mud will enter through the holes on the surface when entering, thereby reducing the impact on the mud. By using the curved plate 2, the position of the reserved steel bar 11 after entering can be limited so that the reserved steel bar 11 is in the middle of the slot 13, and at the same time, the position of the mud to be poured later is freed up, thereby reducing the position deviation of the reserved steel bar 11.
[0027] like Figure 4As shown, a damping spring 3 is fixed to the top of the slot 13; a circular plate 31 is fixed to the end of the damping spring 3; the circular plate 31 and the inside of the slot 13 are slidingly connected; during operation, when the shear wall body 12 falls, an impact force will be generated, and when the end of the reserved steel bar 11 contacts the slot 13, these impact forces will fall on the inner wall of the slot 13, and at this time, the end of the reserved steel bar 11 will contact the circular plate 31. At this time, the damping spring 3 will deform, thereby reducing the impact force, so that the reserved steel bar 11 is buffered when it contacts the circular plate 31, thereby protecting the reserved steel bar 11 and the slot 13 and reducing damage; by using the damping spring 3 for buffering, the characteristic of the damping spring 3 that it will deform by itself when subjected to force can be utilized to unload the impact force, thereby reducing the damage to the reserved steel bar 11 when it contacts the slot 13, thereby providing a protective effect for the reserved steel bar 11 and the circular plate 31.
[0028] like Figure 2 As shown, a circular groove 4 is provided on the surface of the circular plate 31; the circular groove 4 and the reserved steel bar 11 are correspondingly arranged and slidably matched; during operation, when the reserved steel bar 11 enters the slot 13 and contacts the circular plate 31, it will be guided by the arc plate 2 to enter the circular groove 4, thereby limiting the position of the reserved steel bar 11 and reducing the range of movement of the reserved steel bar 11 in the slot 13; by adding the circular groove 4, the reserved steel bar 11 can be fixed when entering the slot 13, narrowing the range of movement, reducing the position movement in the slot 13, and increasing the stability after fixation.
[0029] like Figures 1 to 5 As shown, a square ring 5 is fixed to the surface of the square plate 15; the square ring 5 and the thread groove 16 are correspondingly arranged; during operation, when the pipe needs to be inserted into the thread groove 16 for grouting, the pipe will be offset and needs to be adjusted before it can be inserted into the thread groove 16. When the pipe contacts the surface of the square ring 5, it will move along the surface of the square ring 5 and enter the thread groove 16; by adding the square ring 5, the accuracy of the pipe entering the thread groove 16 can be increased, the time for adjusting the pipe can be reduced, and the fixation of the shear wall body 12 can be accelerated.
[0030] like Figure 5 As shown, the outer wall of the square plate 15 is fixedly connected to a sponge strip 6; the sponge strip 6 and the square plate 15 are correspondingly arranged; during operation, when wet material adheres to the surface of the shear wall body 12, the water source inside it will slide onto the square plate 15, and the sponge strip 6 will absorb the water source to reduce the impact on the bolts 17. At the same time, the water source flowing out from the connection between the square plate 15 and the shear wall body 12 will also be absorbed by the sponge strip 6; by adding the sponge strip 6, the impact of the water source on the bolts 17 can be reduced, and the water in the mud can be reduced from flowing out of the thread groove 16, thereby absorbing the water source.
[0031] Working principle: First, the shear wall body 12 is lifted by a machine and then moved to the top of the base 1, and then the shear wall body 12 is lowered. When lowering, the shear wall body 12 will enter the slot 13. When the shear wall body 12 is lowered, it will contact the guide ring 14 and enter the slot 13 along the surface of the guide ring 14, so that the shear wall body 12 will automatically correct when the position is offset. After the shear wall body 12 enters the slot 13, the pipe is extended into the slot 13 through the threaded groove 16 to pour mud into the slot 13 to fill it. When the filling is completed, the pipe is taken out. After that, the bolt 17 is screwed into the thread groove 16 to block the thread groove 16 so that the mud is blocked and remains in the slot 13; when the reserved steel bar 11 enters the slot 13, the end of the reserved steel bar 11 will contact the surface of the curved plate 2, so that the reserved steel bar 11 moves. When the reserved steel bar 11 completely enters the slot 13, it will be fixed to the middle of the slot 13 by the curved plate 2, so that the position of the slot 13 is fixed in the middle of the slot 13, leaving space for the position of the mud. At the same time, because the surface of the curved plate 2 is porous, the mud will enter through the holes on the surface when entering, thereby reducing the impact on the mud When the shear wall body 12 falls, it will generate an impact force. When the end of the reserved steel bar 11 contacts the slot 13, the impact force will fall on the inner wall of the slot 13. At this time, the end of the reserved steel bar 11 will contact the circular plate 31. At this time, the damping spring 3 will deform to reduce the impact force, so that the reserved steel bar 11 can be buffered when it contacts the circular plate 31, thereby protecting the reserved steel bar 11 and the slot 13 and reducing damage; when the reserved steel bar 11 enters the slot 13 and contacts the circular plate 31, it will be guided by the arc plate 2 and enter the inside of the circular groove 4, thereby limiting the position of the reserved steel bar 11 and reducing The steel bar 11 is reserved with a range of movement inside the slot 13; when the pipe needs to be inserted into the thread groove 16 for grouting, the pipe will be offset and needs to be adjusted before it can be inserted into the thread groove 16. When the pipe contacts the surface of the square ring 5, it will move along the surface of the square ring 5 and enter the thread groove 16; when wet material adheres to the surface of the shear wall body 12, the water inside it will slide onto the square plate 15. At this time, the sponge strip 6 will absorb the water to reduce the impact on the bolt 17. At the same time, the water flowing out from the connection between the square plate 15 and the shear wall body 12 will also be absorbed by the sponge strip 6.
