[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4 The embodiments provided by this utility model are as follows:
[0023] A steel mesh binding device for building construction includes two parallel U-shaped upper plates 1, and U-shaped lower plates 2 are provided on both sides of the U-shaped upper plates 1. The two U-shaped lower plates 2 and the two U-shaped upper plates 1 are arranged in a rectangle. The U-shaped upper plates 1 and U-shaped lower plates 2 that are close to each other are connected by a connecting mechanism. Steel bar placement mechanisms are installed on the inner walls of both sides of the U-shaped upper plates 1 and U-shaped lower plates 2.
[0024] The rebar placement mechanism includes a rotating cylinder 9 with circular holes 13 at both ends. A circular rod 14 is slidably installed in the circular holes 13. A rectangular column 15 is fixedly installed at both ends of the circular rod 14. Circular grooves are opened on the inner walls of both sides of the U-shaped upper plate 1 or the U-shaped lower plate 2. A disc 18 is rotatably installed in each of the two circular grooves. The sides of the two discs 18 that are close to each other are fixedly connected to both ends of the rotating cylinder 9. A rectangular groove is opened on the sides of the two discs 18 that are close to each other. The ends of the two rectangular columns 15 that are far apart from each other extend into the two rectangular grooves and are fixedly installed with springs 16. The ends of the two springs 16 that are far apart from each other are fixedly installed on the sides of the two rectangular grooves that are far apart from each other. Multiple rows of placement components are evenly installed on the annular side of the rotating cylinder 9. The multiple rows of placement components are connected to the side of the circular rod 14.
[0025] like Figure 2 and Figure 4 As shown, the placement assembly includes multiple equally spaced placement slots 10 opened on the side of the rotating cylinder 9. Each of the multiple placement slots 10 has a clamping hole 11 on its inner wall. The multiple clamping holes 11 are connected to the round hole 13. Each of the multiple clamping holes 11 has a clamping plate 12 slidably installed in it. One end of the multiple clamping plates 12 extends into the placement slot 10, and the other end of the multiple clamping plates 12 is fixedly connected to the side of the round rod 14.
[0026] With the above structure: rotating the cylinder 9 allows different placement components to face upwards, switching between placement slots 10 with different intervals to meet the binding requirements of different rebar spacings. Then, by pulling the clamp 12, the round rod 14 can be moved. The movement of the round rod 14 moves two rectangular columns 15, which causes two springs 16 to deform. Then, the lower rebar is first placed on the multiple upward-facing placement slots 10 on the U-shaped lower plate 2, and then placed on the multiple upward-facing placement slots 10 on the U-shaped upper plate 1. Through the setting of multiple clamps 12 and springs 16, the placed rebar can be limited, making it easy to bind.
[0027] like Figure 1 As shown, the spacing between two adjacent placement slots 10 in placement components located in different columns is different. Because the spacing between placement slots 10 in different columns is different, after switching placement components between different columns, the diameters of two adjacent reinforcing bars are different after the reinforcing bars are tied in the placement slots 10, thus meeting the tying requirements for different reinforcing bar spacings.
[0028] like Figure 4 As shown, the rebar placement mechanism also includes a threaded hole on the inner wall of the circular groove, with a bolt 8 threaded into the hole. The annular side of the spring 16 has multiple slots 17, each corresponding to a different row of placement components. One end of the bolt 8 extends into one of the slots 17. By rotating the bolt 8, it enters the slot 17, thus fixing the rotating cylinder 9.
[0029] like Figure 2 As shown, the connecting mechanism includes mounting blocks 4 and mounting posts 3. Mounting blocks 4 are mounted on the side of the U-shaped lower plate 2, and mounting posts 3 are fixedly mounted on the side of the U-shaped upper plate 1. The side of the mounting blocks 4 has a groove, and one end of the mounting post 3 extends into the groove. A stud 6 is fixedly mounted on the side of the mounting post 3. A slot 5 is opened on the inner wall of the groove, and one end of the stud 6 passes through the slot 5 and is threaded with a nut 7. Rotate the four nuts 7 away from the four mounting blocks 4, and then adjust the position of the two U-shaped upper plates 1 so that the upper steel bar can contact the bottom of the lower steel bar after being placed, which is convenient for later binding. After adjustment, rotate the four nuts 7 in the opposite direction so that they abut against the sides of the four mounting blocks 4 respectively, thereby completing the fixation. Then, place the lower steel bar on the multiple upward-facing placement slots 10 on the U-shaped upper plate 1. The bottom and top inner walls of the slots 5 leave gaps with the sides of the stud 6. The advantage of this design is that it allows the stud 6 to move up and down, thereby adjusting the connection position between the lower U-shaped plate 2 and the upper U-shaped plate 1. When switching and binding reinforcing bars of different thicknesses, the upper and lower reinforcing bars can make contact.
[0030] like Figure 2 and Figure 4 As shown, the clamping plate 12 is located in the middle of the clamping hole 11. The advantage of this arrangement is that the clamping plate 12 can move within the clamping hole 11, making it convenient to clamp steel bars of different thicknesses.
[0031] Working principle:
[0032] When in use, according to the required spacing of the reinforcing bars, rotate bolt 8 to move it out of slot 17, and then rotate cylinder 9 to make different placement components face upwards, switch different spacing placement slots 10. When the required placement slot 10 is facing upwards, rotate bolt 8 in the opposite direction to make it enter slot 17, thereby completing the fixing of rotating cylinder 9. Then, place the lower reinforcing bar on the multiple upward-facing placement slots 10 on the U-shaped lower plate 2. After placement, rotate four nuts 7 to move them away from the four mounting blocks 4. Then adjust the position of the two U-shaped upper plates 1 so that the upper reinforcing bar can contact the bottom of the lower reinforcing bar after placement, which is convenient for later binding. After adjustment, rotate four nuts 7 in the opposite direction to abut against the sides of the four mounting blocks 4 respectively, thereby completing the fixing. Then place the lower reinforcing bar on the multiple upward-facing placement slots 10 on the U-shaped upper plate 1.
[0033] Before the reinforcing bars are placed in the placement slot 10, the round rod 14 can be moved by pulling the clamp 12. The movement of the round rod 14 moves two rectangular columns 15, which in turn causes two springs 16 to deform. By setting multiple clamps 12, the placed reinforcing bars can be limited, and reinforcing bars of different thicknesses can be limited. At the same time, when the placement slots 10 with different intervals are switched, the clamps 12 also switch accordingly, which facilitates the simultaneous limitation of reinforcing bars with different intervals and facilitates subsequent binding.
[0034] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
