Description

Technical Field

[0001] The utility model relates to the technical field of steel cage binding, in particular to a spliced ​​steel cage positioning fixture. Background Art

[0002] The binding of cylindrical steel cages is an important part of steel reinforcement engineering, and its quality and precision are directly related to the safety and stability of the entire structure.

[0003] The binding steps:

[0004] Main reinforcement installation: Determine the number and location of the main reinforcement based on the height and diameter of the cylindrical reinforcement cage. Use a level or theodolite to level and center the main reinforcement, ensuring it is on the same horizontal plane and perpendicular to the centerline of the cylinder. Secure the main reinforcement with wire or welding to prevent shifting during the binding process.

[0005] Installation of stiffening hoops: Mark the locations of the stiffening hoops on the main bars according to the design requirements. Slide the stiffening hoops over the main bars and secure them using wire or spot welding. Ensure that the stiffening hoops are perpendicular to the main bars and that the spacing meets the design requirements.

[0006] In the above steps, in order to ensure that the spacing of the main reinforcement is equal, a positioning fixture is required. Conventional positioning fixtures are generally set inside the steel cage, and the main reinforcement is placed on the outer side of the fixture. Then the main reinforcement is connected to the reinforcing hoop with wire or welding. However, after the reinforcing hoop is welded, the fixture is difficult to remove, and finally the fixture has to be fixed together with the steel cage. Utility Model Content

[0031] See also Figure 3-4 A protrusion 9 is fixedly mounted on one end of the curved rod 7, and a groove 10 corresponding to the protrusion 9 is formed on the other end of the curved rod 7. The sides, front, and back of the groove 10 are all open. The protrusions 9 slide through each other from the front or back of the groove 10, facilitating the front-to-back assembly of the four curved rods 7. A bolt 11 is inserted into the interior of the protrusion 9, and a nut 12 is threadedly connected to the outside of the bolt 11. The four curved rods 7 are connected end to end in a circular shape through the protrusion 9, groove 10, bolt 11, and nut 12. Specifically, the four curved rods 7 can be separated by disassembling the bolts 11 and nuts 12.

[0032] See also Figure 5 A threaded hole 13 is provided at the top of the connecting frame 5, and a threaded plug 14 is connected to the internal thread of the threaded hole 13. A cross groove part 15 is fixedly installed on the top of the threaded plug 14, and a spring 16 is provided at the bottom of the threaded plug 14.

[0033] See also Figure 5 The surface of the crossbar 4 is provided with a slot corresponding to the plug 18. The end of the plug 18 that inserts into the slot is hemispherical. The connecting frame 5 is removably connected to the crossbar 4 via the threaded plug 14, spring 16, plug 18, stopper 17, and slot. Specifically, when the connecting frame 5 is mounted on the crossbar 4, the sound produced by the spring 16 pushing the plug 18 against the crossbar 4 indicates that the connecting frame 5 is correctly installed.

[0034] See also Figure 6 A steel cage 20 is installed inside the L-shaped support plate 8, and electric lifting platforms 19 are set on both sides of the bottom of the steel cage 20. When the steel cage 20 is assembled, its overall volume is large and heavy. Therefore, the electric lifting platform 19 can be used to lift the steel cage 20, which is convenient for disassembly of the positioning fixtures installed inside the steel cage 20 or at both ends of the steel cage 20.

[0035] Working principle: When in use, after the welding of the steel cage body 20 is completed, the electric lifting platform 19 is used to lift the steel cage body 20, and the positioning fixtures at both ends or the internal positioning fixtures are no longer under force. Then the cross bar 4 is pulled out from the support frame 3, and then the vertical frame 2 and the support frame 3 are pulled out from the gap between the steel cage body 20, and then the bolts 11 and nuts 12 are disassembled, and the arc rod 7 is pushed forward or backward, the protrusion 9 and the groove 10 will separate from each other, and then the four arc rods 7 will be offset and separated front and back, and then the arc rod 7 is slightly rotated to allow the L-shaped support plate 8 to be offset from the main reinforcement of the steel cage, and the four arc rods 7 can be taken out one by one, thereby achieving the purpose of disassembling and removing the positioning fixtures.

[0036] The four arc rods 7 are connected end to end through the protrusions 9, grooves 10, bolts 11 and nuts 12. At the same time, the four connecting frames 5 are also arranged neatly at equal intervals. Then the connecting frame 5 is flush with the support frame 3, and the cross bar 4 is inserted into the support frame 3. The spring 16 pushes the plug 18 to be stuck in the groove on the surface of the cross bar 4. According to the sound of the plug 18 hitting the groove, it can be judged that the installation position of the connecting frame 5 on the cross bar 4 is accurate. It can also prevent the connecting frame 5 from sliding on the cross bar 4, thereby improving the stability of the four arc rods 7 after combination.

[0037] After the four arc rods 7 are assembled with the support frame 3, the vertical frame 2 and the bottom plate 1, the main reinforcement can be placed in the L-shaped support plate 8, and then fixed with multiple annular main reinforcements using a reinforcing hoop to ensure that the steel cage 20 will not collapse during the initial binding.
