Furthermore, the three cross beams 102 are evenly spaced apart, the distance between the first cross beam 102 and the third cross beam 102 is smaller than the length of the longitudinal beam 101, and the two ends of the second cross beam 102 are respectively connected to the midpoints of the two longitudinal beams 101. Finally, a square frame of the tire frame overall framework 1 is formed between the multiple longitudinal beams 101 and the multiple cross beams 102. When in use, the tire frame overall framework 1 is square in a top view.

[0031] A plurality of sliding beams 201 are arranged between the tops of the two longitudinal beams 101. The plurality of sliding beams 201 are parallel to each other and are connected perpendicularly to the longitudinal direction. The length of each sliding beam 201 is greater than the spacing between the two longitudinal beams 101, so that after each sliding beam 201 is connected to the two longitudinal beams 101, both ends of the sliding beam 201 can extend to the outside of the longitudinal beams 101. In this embodiment, three sliding beams 201 are arranged, and the three sliding beams 201 are sequentially divided into a first sliding beam 201, a second sliding beam 201 and a third sliding beam 201 along the arrangement direction. The three sliding beams 201 are all movably connected to the longitudinal beams 101.

At this time, by adjusting the sleeve connection position of the sliding sleeve 701 and the sliding beam 201 and the tightening position of the nut 105, the lateral adjustment of the sliding beam 201 can be achieved. It should be noted that the number of the sliding devices 7 is determined according to the number of the support plates 11 in the construction drawings, and the sliding sleeve 701 should be inserted into the sliding beam 201 before the base section 601 is fixedly connected to the bottom plate of the sliding beam 201 .

The two arc-shaped tracks are arranged symmetrically. The deflection fixing device 8 is sleeved on the sliding ear plate 702 of the sliding device 7 through the limiting U-shaped plate 801.

The top of the limiting U-shaped plate 801 is used to install the support plate 11, which is fixed on the top of the limiting U-shaped plate 801 by the F clamp 802, and the support plate 11 is welded with a limiting frame 9, which is used to limit the relative distance between the steel bars 4. The number of the second fine-rolled threaded steel 202 is one, and the second fine-rolled threaded steel 202 passes through the first small hole of the sliding ear plate 702 and the second small hole of the limiting U-shaped plate 801 and is then tightened with a nut 105 to achieve the connection between the limiting U-shaped plate 801 and the sliding ear plate 702. The number of the third fine-rolled threaded steel 5 is two, and the two third fine-rolled threaded steel 5 pass through the first small hole of the sliding ear plate 702 and the arc-shaped track of the limiting U-shaped plate 801, and are tightened with a nut 105 after adjusting the angle of the limiting U-shaped plate 801 relative to the sliding ear plate 702, so that the limiting U-shaped plate 801 and the support plate 11 can be adjusted in angle, and finally the sliding beam 201 can be adjusted in angle.

[0036] In the present invention, a plurality of sliding beams 201 which can slide in three directions, including longitudinal, transverse and vertical directions, are arranged on the overall frame 1 of the tire frame, and the angle of adjacent sliding beams 201 can also be adjusted by adjusting the angle of the support plate 11, thereby solving the problem that the existing steel bar 4 binding tire frames can usually only be used for the binding work of steel bar 4 sheets of specified specifications, and a variety of steel bar 4 binding tire frames are required for steel bar 4 sheets of different specifications and special-shaped steel bar 4 sheets, which is not only inconvenient to use but also increases the cost.

[0037] This embodiment also discloses a method for using a position-limiting frame and a steel bar positioning assembly frame, comprising the following steps:

[0038] According to the design drawings and the actual on-site layout correction, the shape of the support plate 11 is cut out, the relative distance between the support plates 11 and the subsequent welding angle with the steel frame 12 are calculated, and the relative distance between the limit frames 9 and the height difference after being leveled are calculated. Then, according to the relative distance between the limit frames 9 and the height difference after being leveled, it is determined whether the middle section 602 and the bottom section 603 of the extension device 6 need to be set, and the position of the sliding beam 201 on the longitudinal beam 101 is adjusted. Then, according to the relative distance between the support plates 11, the sliding device 7 and the deflection are determined. After the position of the fixing device 8 and the required number are reached, the initial tightening is performed, and then the deflection fixing device 8 is adjusted according to the subsequent welding angle between the support plate 11 and the steel frame 12 and finally tightened, and then the support plate 11 is inserted and clamped with the F clamp 802, and then the limiting slotted main board 901 and the vertical reinforcement plate 902 of the limiting frame 9 are welded, and the steel bars 4 are fed horizontally and the end plates 903 are welded and the steel bars 4 are fixed with binding wires to form steel bar 4 sheets. Finally, the F clamp 802 is loosened, the steel bar 4 sheets are hoisted to the steel frame 12 for positioning, and then the support plate 11 is directly welded.

[0039] By converting the steel bar 4 from vertical installation to horizontal installation and inserting it into the limited slot main board 901 and fixing it, the steel bar 4 mesh formed on the tire frame and the partial assembly of the steel frame 12 can be constructed simultaneously, and the subsequently formed steel bar 4 mesh can be directly lifted to the corresponding position of the steel frame 12 for welding, which can simplify the installation process, improve the installation quality and save a lot of construction time.

Then, according to the relative distance between the limiting frames (9) and the height difference after being leveled, it is determined whether the middle section (602) and the bottom section (603) of the extension device (6) need to be set, and the position of the sliding beam (201) on the longitudinal beam (101) is adjusted. Then, according to the relative distance between the support plates (11), the sliding device (7) and the deflection fixing device ( 8) and the required number are determined, and then the deflection fixing device (8) is initially tightened, and then the deflection fixing device (8) is adjusted according to the subsequent welding angle between the support plate (11) and the steel frame (12) and finally tightened, and then the support plate (11) is inserted and clamped with the F clamp (802), and then the limiting slotted main board (901) and the vertical reinforcing plate (902) of the limiting frame (9) are welded, and the steel bars (4) are fed horizontally and the end plates (903) are welded and the steel bars (4) are fixed with binding wires to form a steel bar (4) sheet body, and finally the F clamp (802) is loosened, the steel bar (4) sheet body is hoisted to the steel frame (12) for positioning, and then the support plate (11) is directly welded.
