[0028] The following will be combined Figure 1-Figure 7 The present invention is further described with reference to the accompanying drawings and examples.

[0029] This embodiment discloses a position-limiting frame and a steel bar positioning assembly frame.

[0030] Reference Figures 1 to 7 The limited skeleton and steel bar positioning assembly tire frame includes a tire frame 1 composed of a plurality of longitudinal beams 101 and a plurality of transverse beams 102, wherein the plurality of longitudinal beams 101 are parallel to each other, the plurality of transverse beams 102 are parallel to each other, the longitudinal beams 101 and the transverse beams 102 are fixedly connected perpendicularly to each other, and the length of the longitudinal beams 101 is greater than the length of the transverse beams 102. In this embodiment, there are two longitudinal beams 101 and three transverse beams 102. The three transverse beams 102 are perpendicularly connected between two mutually parallel longitudinal beams 101. The two end surfaces of each transverse beam 102 are respectively connected between two longitudinal opposite surfaces, and the top surface of the transverse beam 102 is at the same height as the top surface of the longitudinal beam 101. 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-shaped tire frame overall frame 1 is formed between the multiple longitudinal beams 101 and the multiple cross beams 102. When in use, the tire frame overall frame 1 is square-shaped when viewed from above.

[0031] Several sliding beams 201 are disposed between the tops of the two longitudinal beams 101. The sliding beams 201 are parallel to each other and connected perpendicularly to the longitudinal direction. The length of each sliding beam 201 is greater than the spacing between the two longitudinal beams 101. This allows each sliding beam 201 to be connected to the two longitudinal beams 101, with both ends of the sliding beam 201 extending outward from the longitudinal beams 101. In this embodiment, three sliding beams 201 are provided. The three sliding beams 201 are sequentially arranged along the arrangement direction to form a first sliding beam 201, a second sliding beam 201, and a third sliding beam 201. All three sliding beams 201 are movably connected to the longitudinal beams 101.

[0032] The longitudinal beam 101 is sequentially provided with multiple groups of sliding modules, jacks 3, extension devices 6, sliding devices 7, deflection fixing devices 8 and support plates 11. Each group of sliding modules, jacks 3, extension devices 6, sliding beams 201, sliding devices 7, deflection fixing devices 8 and support plates 11 are connected in sequence along the vertical direction, wherein the sliding module includes a base, a driving member arranged on the base and a slider driven by the driven member. Blocks 10 are welded on both sides of the base. The blocks 10 on both sides of the base are symmetrically clamped on both sides of the top flange of the longitudinal beam 101 to achieve lateral limitation. The slider slides along the length direction of the longitudinal beam 101 under the driving action of the driving member to achieve longitudinal movement. Furthermore, a first reaction seat 103 is provided on the top of both ends of the first crossbeam 102 and the third crossbeam 102, and a first fine-rolled threaded steel bar 104 is passed through the two first reaction seats 103 opposite to each other in the longitudinal direction and tightened with a nut 105. At the same time, the first fine-rolled threaded steel bar 104 also passes through the stop block 10 of the base of the sliding module and is tightened with a nut 105, thereby finally fixing the base of the slider module.

[0033] The jack 3 includes a fixed end and a telescopic end. The fixed end of the jack 3 is mounted on the base of the sliding module, while the movable end of the jack 3 faces vertically upward. The sliding beam 201 is height-adjustable using the jack 3. An extension device 6 is mounted on top of the telescopic section of the jack 3. The extension device 6 is divided into three sections from top to bottom: a base section 601, a middle section 602, and a bottom section 603. The extension device 6 is used to supplement the lifting capacity of the jack 3. The lifting capacity of the extension device 6 is adjusted according to the number of sections selected. The combination of the jack 3 and the extension device 6 increases the height adjustment range of the sliding beam 201 and enables vertical adjustment of the sliding beam 201. Each section of the extension device 6 is provided with two circular holes in the vertical direction. The fourth fine-rolled threaded steel bar 604 passes through the circular holes of each section of the extension device 6 and is tightened with a nut 105. The length of the fourth fine-rolled threaded steel bar 604 is selected according to the number of sections of the extension device 6. Finally, the fourth fine-rolled threaded steel bar 604 is used to realize the connection between the sections of the extension device 6.

[0034] The sliding device 7 is arranged at the top of the extension device 6. The sliding device 7 includes a sliding sleeve 701 and a sliding ear plate 702. The sliding sleeve 701 is arranged on the base section 601 of the extension device 6 and is sleeved on the sliding beam 201. The sliding ear plate 702 is arranged on the top of the sliding sleeve 701. The sliding ear plate 702 has three first small holes, two of which are symmetrically arranged. Furthermore, a second reaction seat 13 is provided at the top of each end of the sliding beam 201. Three high-quality threaded steel bars are inserted between the two opposing second reaction seats 13 on the sliding beam 201 and tightened with nuts 105. The three high-quality threaded steel bars are respectively the second high-quality threaded steel bar 202 and the third high-quality threaded steel bar 5. The three high-quality threaded steel bars pass through the three first small holes and are tightened with nuts 105. At this time, the sleeve position of the sliding sleeve 701 and the sliding beam 201 and the tightening position of the nuts 105 are adjusted. It should be noted that the number of sliding devices 7 is determined according to the number of 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 fixed to the bottom plate of the sliding beam 201.

[0035] The deflection fixture 8 is disposed on top of the sliding device 7 and includes a limiting U-shaped plate 801 and an F-clip 802. A second small hole is formed at the bottom of the limiting U-shaped plate 801. The limiting U-shaped plate 801 defines two arc-shaped tracks around the second small hole, with the two first small holes on the outer side of the sliding lug plate 702 as the radius. The two arc-shaped tracks are symmetrically arranged. The deflection fixture 8 is mounted on the sliding lug plate 702 of the sliding device 7 via the limiting U-shaped plate 801. After mounting, the second small hole of the limiting U-shaped plate 801 is aligned with the first small hole in the middle of the sliding lug plate 702, and the two arc-shaped tracks of the limiting U-shaped plate 801 are aligned with the two second small holes on the outer side of the sliding lug plate 702. The top of the limiting U-shaped plate 801 is used to install the support plate 11, which is fixed to 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 bar 202 is one, and the second fine-rolled threaded steel bar 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 bar 5 is two, and the two third fine-rolled threaded steel bars 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 angle of the limiting U-shaped plate 801 and the support plate 11 can be adjusted.

[0036] In the present invention, a number of sliding beams 201 that can slide in three directions, including longitudinal, transverse and vertical directions, are provided on the overall frame 1 of the tire frame, and the angles of adjacent sliding beams 201 can also be adjusted by adjusting the angles of the support plates 11, thereby solving the problem that the existing steel bar 4 binding tire frames can usually only be used for binding steel bar 4 sheets of specified specifications. For steel bar 4 sheets of different specifications and special-shaped steel bar 4 sheets, a variety of steel bar 4 binding tire frames are required, 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, the relative distance between the limit frames 9 and the height difference after being leveled are calculated, and then according to the relative distance between the limit frames 9 and the height difference after being leveled, it is decided 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 is adjusted to the required number, 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 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 and 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 a vertical installation to a horizontal installation and snapping it into the limited slot main board 901 and fixing it, the steel bar 4 mesh formed on the 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.

[0040] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of this application. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
