[0041] Specifically, two support frames 1 can be arranged opposite to each other and spaced apart to support the two ends of the steel bar 16 respectively.

[0042] The support frame 1 includes a column 2, a cross beam 4, a first locking member 6, a support member 7 and a second locking member 8.

The first length scale mark 3 is distributed along the axis direction of the column 2. The relative position of each crossbeam 4 can be conveniently and accurately determined through the first length scale mark 3, avoiding repeated measurement and adjustment.

[0044] The support member 7 can slide back and forth along the axial direction of the beam 4. A second length scale mark 5 is provided on the beam 4.

[0045] The first locking member 6 enables the cross beam 4 to selectively slide or remain stationary relative to the column 2, and the second locking member 8 enables the support member 7 to selectively slide or remain stationary relative to the cross beam 4. After adjusting the positions of each cross beam 4 and the support member 7, the first locking member 6 and the second locking member 8 are used to fix the positions of the cross beam 4 and the support member 7, so as to place the steel bars 16 on the support member 7 and ensure the relative stability of each support member 7 during the binding process, thereby ensuring the stability of the position of each steel bar 16, solving the problem of the steel bar position accuracy of the steel bar skeleton in the prior art, ensuring the quality of the steel bar skeleton, reducing the labor intensity of the operator, saving labor, and greatly improving the production efficiency of the steel bar skeleton.

[0046] The steel bar skeleton assembly tool for prefabricated columns provided in this embodiment can not only improve the steel bar position accuracy of a single steel bar skeleton and complete the binding of steel bar skeletons of different specifications (such as different cross-sectional sizes), but can also be used for mass production to ensure that the steel bar position accuracy of steel bar skeletons of the same specification has a higher consistency.

[0047] In this embodiment, the columns 2 are arranged in pairs. Specifically, each support frame 1 includes a pair of columns 2. The pair of columns 2 are parallel to each other and distributed at intervals. The distribution direction of the pair of columns 2 is perpendicular to the axis of the column 2 and the distribution direction of the two support frames 1.

[0048] The cross beam 4 is arranged between a pair of columns 2, and the axis of the cross beam 4 is perpendicular to the axis of the column 2. Both ends of the cross beam 4 are connected to the columns 2, and a first locking member 6 is arranged at each end of the cross beam 4, which not only enables the cross beam 4 to slide smoothly relative to the column 2, but also ensures the position stability of the cross beam 4 after the position of the cross beam 4 is fixed.

[0049] Regarding the connection structure between the crossbeam 4 and the column 2, in the embodiment of the utility model, a first sliding hole 9 is provided on the column 2, the axis of the first sliding hole 9 is perpendicular to the axis of the column 2, and the first sliding hole 9 passes through the column 2 along its own axis. The first sliding hole 9 is a strip hole extending along the axis of the column 2.

[0050] A slide bar 10 is provided at the end of the cross beam 4, one end of the slide bar 10 is fixedly connected to the cross beam 4, and the other end passes through the first slide hole 9.

[0052] The first locking member 6 is threadedly connected to the end of the slide bar 10 away from the cross beam 4, and the first locking member 6 can abut against the column 2. By utilizing the abutment between the first locking member 6 and the column 2 and the abutment between the end of the cross beam 4 and the column 2, the cross beam 4 and the slide bar 10 can be restricted from sliding relative to the column 2, thereby achieving relative fixation between the cross beam 4 and the column 2.

[0053] The first locking member 6 may be, but is not limited to, a nut. Specifically, a butterfly nut may be selected as the first locking member 6 for easy screwing.

[0054] Regarding the connection structure between the support member 7 and the cross beam 4, in the embodiment of the utility model, a second sliding hole 11 is provided on the cross beam 4, the axis of the second sliding hole 11 is perpendicular to the axis of the cross beam 4, and the second sliding hole 11 passes through the cross beam 4 along its own axis. The second sliding hole 11 is a strip hole extending along the axis of the cross beam 4.

[0055] The support member 7 includes a connecting portion 12 and a supporting portion 17 . The supporting portion 17 is connected to the connecting portion 12 , and the supporting portion 17 is used to support the steel bar 16 .

[0056] The connecting portion 12 passes through the second sliding hole 11 , and the connecting portion 12 can slide along an extending direction of the second sliding hole 11 .

[0057] The second locking member 8 is threadedly connected to at least one end of the connecting portion 12 away from the supporting member 7 , and the second locking member 8 is used to abut against the crossbeam 4 .

[0058] The second locking member 8 may be, but is not limited to, a nut. Specifically, a butterfly nut may be selected as the second locking member 8 for easy screwing.

[0059] In this embodiment, a positioning groove 13 is formed on the supporting portion 17, the axis of the positioning groove 13 is perpendicular to the axis of the column 2 and the axis of the beam 4, and the positioning groove 13 passes through the supporting portion 17 along its own axis direction. When the steel bar 16 is placed on the supporting portion 17, the steel bar 16 is located in the positioning groove 13, and the positioning groove 13 can limit the rolling of the steel bar 16, improve the position stability of the steel bar 16, and prevent the steel bar 16 from being dislocated.

[0060] In this embodiment, the connecting portion 12 and the supporting portion 17 are configured as a rod-shaped structure, the axis of the connecting portion 12 is parallel to the axis of the column 2, the axis of the supporting portion 17 extends along a semicircular arc, and one end of the supporting portion 17 is connected to one end of the connecting portion 12. The plane where the supporting portion 17 is located is parallel to the plane formed by the crossbeam 4 and the column 2, and the supporting portion 17 can enter and exit the second sliding hole 11.

[0061] Reference Figure 5, the supporting part 17 is located below the cross beam 4, the second locking member 8 is located above the cross beam 4, and the supporting part 17 cooperates with the cross beam 4 to form a channel for the steel bar 16 to pass through. The relative position of the supporting part 17 and the cross beam 4 can be adjusted by screwing the second locking member 8, so that the height dimension of the channel formed by the supporting part 17 and the cross beam 4 can be adjusted. After the steel bar 16 is placed on the supporting part 17, the relative position of the supporting part 17 and the cross beam 4 is adjusted so that the height dimension of the formed channel is consistent with the diameter of the steel bar 16, so that the supporting part 17 presses the steel bar 16 against the cross beam 4, so that the position of the steel bar 16 remains fixed. When tying the steel bars 16, the position of each steel bar 16 is fixed, and there will be no problem of position displacement due to external force.

[0062] Generally, the diameter of the steel bar 16 is 14 to 40 mm. In this embodiment, the diameter of the semicircular arc is set to be greater than or equal to 40 mm, so that the supporting portion 17 can support, position and fix most of the steel bars 16, and has strong adaptability.

[0063] In a specific embodiment, the supporting portion 17 and the connecting portion 12 are integrally formed, and can be formed by using a rod through a bending process.

[0064] Two second locking members 8 may also be provided, and the two second locking members 8 are distributed on both sides of the cross beam 4 along the axial direction of the connecting portion 12, and the two second locking members 8 are both threadedly connected to the connecting portion 12. Through the abutment between the two second locking members 8 and the cross beam 4, the support member 7 can be restricted from sliding relative to the cross beam 4, thereby achieving relative fixation of the support member 7 and the cross beam 4.

[0065] At this time, only the second locking member 8 located on the side of the cross beam 4 away from the supporting portion 17 can be set as a butterfly nut, and the other second locking member 8 can be set as a common nut.

[0066] In the embodiment of the utility model, at least one of the upright column 2 and the cross beam 4 is provided with an armrest 14 , which can facilitate the operator to apply force to the support frame 1 when adjusting the position of the support frame 1 .

[0067] Reference Figure 4 , an armrest 14 is provided on the column 2, and a plurality of armrests 14 are provided, and the plurality of armrests 14 are distributed along the axis direction of the column 2. In the specific use process, the armrests 14 are distributed at different heights, and operators of different heights and different postures of the operators can all touch the armrests 14, which is convenient for operation and has strong adaptability.

[0068] In the embodiment of the utility model, the steel frame assembly tool for prefabricated columns also includes rails and limit blocks.

[0069] The track can be fixed horizontally on the ground, and two support frames 1 are arranged on the track, and the axis of the track is perpendicular to the axis of the crossbeam 4 and the axis of the column 2 .

[0070] At least one of the two support frames 1 can slide back and forth along the axis direction of the track, so that the distance between the two support frames 1 can be adjusted. In the specific use process, the support members 7 of the two support frames 1 support the two ends of the steel bars 16. By adjusting the distance between the two support frames 1, steel bars 16 of different lengths can be supported, and steel bar skeletons of different lengths can be tied.

[0071] Each support frame 1 corresponds to at least two limit blocks, and the two limit blocks are distributed on both sides of the support frame 1 along the axial direction of the track. The limit blocks are used to abut against the support frame 1.

[0072] The limit block is detachably arranged on the track. The limit block is fixed on the track. Through the interaction between the support frame 1 and the two limit blocks, the support frame 1 can be restricted from sliding relative to the track, thereby ensuring the stable position of the support frame 1.

[0073] Specifically, each support frame 1 includes two columns 2, and each column 2 corresponds to two limit blocks, that is, each support frame 1 corresponds to four limit blocks.

[0074] The limit block may be, but is not limited to, a magnetic box, which has a button, and the magnetic box can be adsorbed on the track or removed from the track by operating the button.

[0075] In the embodiment of the utility model, the support frame 1 further includes a base 15, which is fixedly connected to one end of the column 2 close to the track, and the base 15 slides with the track. In other words, the column 2 slides with the track through the base 15, and the contact area between the base 15 and the track is larger than that between the column 2 and the track. The stability of the support frame 1 is higher.

[0076] When using the steel frame assembly tool for prefabricated columns provided by the embodiment of the utility model to tie the steel frame of the prefabricated column, it is necessary to first understand the spacing between the steel bars 16 of the steel frame and the length of the steel bars 16, and then adjust the spacing between the two support frames 1 according to the length of the steel bars 16. After adjusting the position of the support frame 1, fix the position of the support frame 1. Then adjust the position of the crossbeam 4 on each support frame 1 according to the vertical spacing of each steel bar 16 (the spacing of each steel bar 16 along the axial direction of the column 2), and fix the position of the crossbeam 4 after adjusting the position of the crossbeam 4. Finally, adjust the position of the support member 7 on each crossbeam 4 according to the horizontal spacing of each steel bar 16 (the spacing of each steel bar 16 along the axial direction of the crossbeam 4), and after adjusting the position of the support member 7 and placing the steel bar 16, screw the second locking member 8 to fix the position of the support member 7 and the position of the steel bar 16. Finally, use stirrups and the like to tie the steel bars 16 on the steel frame assembly tool for prefabricated columns.
