[0002] In building construction, the construction technology of a fully cast-in-place exterior wall of an aluminum alloy formwork is widely used due to its advantages such as high construction efficiency and good forming quality. However, during this construction process, the positioning of exterior wall steel bars is a crucial and challenging link.

[0003] Currently, the steel bar positioning method mainly relies on manual measurement and marking. This method has many drawbacks. Manual operation is prone to problems such as uneven steel bar spacing and positioning deviation, which affect the structural performance and overall quality of the exterior wall.

[0039] Embodiment 3

[0040] As Figure 1-13As shown in the figure, on the basis of Embodiment 1, the present invention provides a technical solution: Preferably, the installation mechanism includes a first mounting plate 11. One side of the first mounting plate 11 is fixedly connected with a fixing plate 12. A first screw rod 13 is threadedly connected inside the fixing plate 12. The lower end of the first screw rod 13 is rotatably connected with a pressing block 14; a stretching mechanism, the stretching mechanism includes a worm gear 21.

A third screw rod 42 is threadedly connected inside the movable clamp. One end of the third screw rod 42 is fixedly connected with a handle 43; a driving mechanism, the driving mechanism includes a motor 51. One end of the rotating shaft of the motor 51 is fixedly connected with a worm 52. The surface of the worm 52 is engaged with the surface of the worm gear 21; an aluminum alloy template mechanism, the aluminum alloy template mechanism includes a side template 61. An end template 62 is arranged at the end of the side template 61. The clamping mechanism further includes a fixed clamp. The structure of the fixed clamp is the same as that of the movable clamp.

A second limiting screw 444 is threadedly connected inside the limiting block 443. The top of the second slider 441 is engaged with a replacement part 445. The top of the replacement part 445 is lapped with the bottom of the limiting block 443. A clamping surface enlarging plate 446 is fixedly connected to the surface of the replacement part 445. The driving mechanism further includes a shaft seat 53. The bottom of the shaft seat 53 is fixedly connected with a third slider 54.

[0041] In this embodiment, when the steel bar type does not match the radian of the clamping surface expansion plate 446, loosen the second limit screw 444, then the limit block 443 can be pushed to slide along the sliding rod 442, and separated from the top of the replacement part 445, so that the replacement part 445 can be taken out from the second slider 441 for replacement, making its adaptability stronger. Then rotate the push rod 24 to make the surface of the second bevel gear 23 mesh with the surfaces of the first bevel gear 22 and the third bevel gear 26. Then rotate the lock nut 25 to prevent the second bevel gear 23 from driving the push rod to rotate, so that when the worm gear 21 rotates, it can drive the third bevel gear 26 to rotate. Then start the upper motor 51 to make the upper worm 52 drive the worm gear in the displacement assembly 32 to rotate, thereby driving the clamping mechanism to move back and forth to adjust the position of the steel bar. After the adjustment is completed, similarly, start the lower motor 51 to make the lower worm 52 drive the worm gear 21 to rotate, and then drive the second screw 27 to rotate through the transmission of the bevel gears. By the rotation of the second screw 27, drive the first slider 28 to slide along the first slide rail 29, thereby making the clamping mechanism move outward along the axial direction of the steel bar to stretch the steel bar, avoiding the middle part of the longitudinal steel bar from sagging, and improving the structural performance and overall quality of the exterior wall.

[0042] Next, the working principle of the steel bar positioning device for the all-cast-in-place exterior wall of the aluminum alloy formwork will be specifically described.

[0043] As Figure 1-13As shown, during use, first, an aluminum alloy mold mechanism is erected at a preset position. The side formwork 61 and the end formwork 62 are assembled into a frame, and the internal space is made to conform to the specifications of the cast exterior wall. Subsequently, the unit positioning module is placed on the surface of the side formwork 61, and the fixed block 15 is brought into contact with the surface of the side formwork 61. Then, the first screw 13 is rotated to push the pressing block 14 downward until it contacts the surface of the side formwork 61, and the positioning unit is installed on the surface of the aluminum alloy formwork mechanism. According to the requirements of the vertical steel bar spacing, after multiple positioning units are installed in the same way, the assembly plate 16 is pulled to insert it into the interior of the adjacent positioning unit. Then, the first limit screw 18 is rotated so that one end of it abuts against the anti-slip pattern 17 on the surface of the assembly plate 16 to fix the position of the assembly plate 16, thereby making multiple positioning units form a whole and making their installation more firm. Subsequently, the driving mechanism equipped with a worm 52 of an appropriate length is installed on the surface of the positioning unit by bolts. During the installation process, the worm gear 21 and the worm 52 are rotated to make the worm 52 mesh with the worm gears 21 in multiple positioning units. When there is a small error between the overall length of multiple positioning units and the length of the worm 52, resulting in misalignment of the installation holes, the third limit screw 57 is loosened so that one end of it disengages from the surface of the second slide rail 55, and then the third mounting plate 56 can be pushed to drive the second slide rail 55 to slide along the interior of the third slider 54, thereby adjusting the installation hole on the surface of the third mounting plate 56 to align it with the installation hole on the surface of the positioning unit for normal installation. Subsequently, another set of driving mechanisms is installed in the same way so that the surface of the worm 52 in the other set of driving mechanisms meshes with the worm gear in the displacement assembly 32, and thus the installation of the driving mechanism is completed. Then, the steel bar is placed on one side of the fixed fixture, and the handle 43 is rotated to make the third screw 42 drive the moving fixture to slide along the second slide rail 41 and gradually approach the static fixture, so that the clamping surface expansion plate 446 tightly abuts against the surface of the steel bar to fix the steel bar. When the steel bar model does not match the curvature of the clamping surface expansion plate 446, the second limit screw 444 is loosened, and then the limit block 443 can be pushed to slide along the slide bar 442 and disengage from the top of the replacement part 445, so that the replacement part 445 can be taken out from the second slider 441 for replacement to make it more adaptable. Subsequently, the push rod 24 is rotated to make the surface of the second bevel gear 23 mesh with the surfaces of the first bevel gear 22 and the third bevel gear 26. Then, the locking nut 25 is rotated to prevent the second bevel gear 23 from rotating and driving the push rod to rotate, so that when the worm gear 21 rotates, it can drive the third bevel gear 26 to rotate. Subsequently, the upper motor 51 is started to make the upper worm 52 drive the worm gear in the displacement assembly 32 to rotate, thereby driving the clamping mechanism to move back and forth to adjust the position of the steel bar. After the adjustment is completed, similarly, the lower motor 51 is started to make the lower worm 52 drive the worm gear 21 to rotate, and then through the transmission of the bevel gears, drive the second screw 27 to rotate. By the rotation of the second screw 27, drive the first slider 28 to slide along the first slide rail 29, and thus make the clamping mechanism move outward along the axial direction of the steel bar.Tensile the steel bars to avoid the middle part of the longitudinal steel bars sagging, and improve the structural performance and overall quality of the exterior wall.

[0044] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
