Description

Technical Field

[0001] The utility model relates to the technical field of steel cage, and particularly relates to a steel cage triangular support with limit and foldable function. Background Art

[0002] Steel cage is a kind of building material widely used in the construction of bridges, high-rise buildings, etc. During the storage, transportation and hoisting of steel cages, deformation is likely to occur. Therefore, "cross" or "triangular" inner lining supports need to be set at certain intervals in the middle of the steel cage to prevent the steel cage from deforming. In previous construction, the inner lining support generally adopted two steel bars cross-welded on the reinforcement bars or three steel bars welded into an inner lining triangle, and the inner lining supports were successively cut and removed before the steel cage was inserted into the hole or after it was inserted into the mold. Although this method can ensure that the steel cage does not deform, it not only causes a large amount of waste of steel bars, but also is time-consuming and laborious, and cannot be adjusted arbitrarily according to the diameter of the steel cage. At the same time, the inner lining support will occupy a large amount of space during the recycling process. Therefore, a steel cage triangular support with limit and foldable function is designed. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a steel cage triangular support with limit and foldable function.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A steel cage triangular support with limit and foldable function of the utility model includes joints, main rods and support rods. Adjusting sleeves and connecting seats are arranged at the ends of the main rods and support rods. Openings are arranged on one side and the bottom of the connecting seat close to the support rod. A first adjusting rod extending into its interior is movably arranged at the end of the adjusting sleeve. The three first adjusting rods are respectively arranged at the ends of the main rod and the two support rods. A second adjusting rod extending into its interior is movably arranged at the other end of the adjusting sleeve. Two groups of polygon grooves are arranged on the three adjusting sleeves in two-by-two groups and distributed up and down. First magnet blocks are arranged on the two polygon grooves at the bottom, and second magnet blocks are arranged on the two polygon grooves at the top.

[0007] In this embodiment, an angle steel is arranged at the end of the second adjusting rod, and it is connected by welding. A welding groove in a "V" shape is arranged at the end of the second adjusting rod.

[0008] In this embodiment, a circular hole for the rotation rod to penetrate is formed at the center of the back surface of the connection seat, and the side length of the connection seat is at least twice that of the cube.

[0009] In this embodiment, a connection block is movably arranged at the end of the second adjusting rod. Two symmetrically distributed connecting rods are arranged on the connection block, and two limiting holes are arranged on both the front and back sides of the adjusting sleeve.

[0010] In this embodiment, the connecting rod penetrates through the limiting hole and is slidably connected thereto. A disc-shaped limiting block is arranged at one end of the connecting rod.

[0011] In this embodiment, telescopic rods are arranged at the centers of the upper and lower ends of the first magnet block.

[0012] In this embodiment, the top block is in the shape of an "inverted trapezoid", and a clamping groove adapted to the top block is formed on one side of the clamping block.

[0013] In this embodiment, two symmetrically distributed fixing plates are fixed at the end of the rotation rod, and two symmetrically distributed connecting plates are fixed on the side surface of the connection seat. Threaded holes on the same horizontal plane are formed in both the fixing plate and the connecting plate, and limiting screws are movably arranged in the threaded holes.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] By arranging a main rod and two support rods in the present utility model, and keeping an included angle of 120° among the three of them during use, using the principle of triangular stability, and at the same time, the support rods can be fixed by limiting screws to keep stable during the support process, with uniform stress and a perfect support system, which can prevent the steel reinforcement cage from deforming during transportation; in addition, when disassembling the triangular support system, equipment such as cutting, electric welding, and gas cutting is not required. Only manual cooperation is needed to turn the first adjusting rod or the second adjusting rod to disassemble it.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a collapsible triangular support for steel reinforcement cages with limit, including a joint 1, a main rod 2 and a support rod 3. Adjusting sleeves 4 and connecting seats 5 are provided at the ends of the main rod 2 and the support rod 3. Openings are provided on one side and the bottom of the connecting seat 5 close to the support rod 3. A first adjusting rod 41 extending into its interior is movably provided at the end of the adjusting sleeve 4. The three first adjusting rods 41 are respectively arranged at the ends of the main rod 2 and the two support rods 3. A second adjusting rod 42 extending into its interior is movably provided at the other end of the adjusting sleeve 4. Two groups of polygonal grooves 401 distributed in a vertical and pairwise manner are provided on the three adjusting sleeves 4. First magnet blocks 402 are provided on the two bottom polygonal grooves 401, and second magnet blocks 406 are provided on the two top polygonal grooves 401. A rotating rod 501 is movably provided on the inner side surface of the connecting seat 5. A cube 502 is provided on the outer surface of the rotating rod 501. The cube 502 is connected to the end of the support rod 3.

[0025] Furthermore, the included angles between the joints 1 are all 120°. The main rod 2 and the two support rods 3 are seamless steel pipes. When in use, the two support rods 3 are rotated upward and the included angle between them and the main rod 2 is kept at 120°. By utilizing the stability of the triangle, the stability of the support of this triangular support for the steel reinforcement cage is improved.

[0026] It should be noted that an angle steel 43 is provided at the end of the second adjusting rod 42, which is connected by welding. A welding groove in a "V" shape is provided at the end of the second adjusting rod 42. This process effectively solves the problems such as large waste of internal support materials in cylindrical steel reinforcement cages, long process time, low construction efficiency, and high cost.

[0027] It can be understood that a circular hole for the rotating rod 501 to penetrate is provided at the center of the back surface of the connecting seat 5. The side length of the connecting seat 5 is at least twice that of the cube 502. The cube 502 can drive the support rod 3 to rotate up and down during the rotation process, facilitating the use and retraction of the support rod 3.

[0028] Please refer to Figure 2 , a connecting block 411 is movably provided at the end of the second adjusting rod 42. Two symmetrically distributed connecting rods 412 are provided on the connecting block 411. Two limiting holes 414 are provided on the front and back sides of the adjusting sleeve 4.

[0029] Furthermore, the connecting rod 412 penetrates through the limiting hole 414 and is slidably connected thereto. A circular cake-shaped limiting block 413 is provided at one end of the connecting rod 412. The connecting rod 412 can slide in the limiting hole 414, facilitating the adjustment of the length of the first adjusting rod 41 or the second adjusting rod 42, and at the same time preventing the first adjusting rod 41 or the second adjusting rod 42 from falling off the adjusting sleeve 4.

[0030] Please refer to Figure 3 , telescopic rods 403 are provided at the centers of the upper and lower ends of the first magnet block 402. A return spring 404 is movably arranged on the outer surface of the telescopic rod 403. A top block 405 is arranged at the other end of the telescopic rod 403. Both ends of the return spring 404 are respectively abutted between the first magnet block 402 and the top block 405. Clamping blocks 407 are provided at both ends of the two polygonal grooves 401 at the top.

[0031] Furthermore, the top block 405 is in the shape of an "inverted trapezoid". A clamping groove adapted to the top block 405 is opened on one side of the clamping block 407. When folding and unfolding this triangular support, rotate the two support rods 3 downward. When the second magnet block 406 approaches the first magnet block 402, the top block 405 is clamped into the clamping groove opened on the clamping block 407, so as to prevent the support rod 3 from rotating and make the recycling more convenient.

[0032] Please refer to Figure 4 , two symmetrically distributed fixing plates 503 are fixed at the end of the rotating rod 501. Two symmetrically distributed connecting plates 504 are fixed on the side surface of the connecting seat 5. Threaded holes 505 are opened on the fixing plates 503 and the connecting plates 504 in the same horizontal plane. A limit screw 506 is movably arranged in the threaded hole 505.

[0033] Specifically, the working principle of this kind of foldable steel cage triangular support with limit: When in use, first adjust the first adjusting rod 41 or the second adjusting rod 42 according to the size of the steel cage to determine the lengths of the main rod 2 and the support rod 3. Then, make the angle steel 43 be clamped into the reinforcing bars of the steel cage, so that it can be kept stable during the supporting process, the force is uniform, the supporting system is perfect, and the steel cage can be prevented from deforming during transportation. When disassembling, first rotate the first adjusting rod 41 or the second adjusting rod 42 to shorten the lengths of the main rod 2 and the support rod 3, and remove the angle steel 43 from the reinforcing bars on the steel cage. Then, rotate the limit screw 506 to release the limiting effect on the support rod 3, which improves the convenience of disassembly. When folding and unfolding, rotate the support rod 3 to move it closer to the main rod 2, and make the second magnet block 406 magnetically attracted to the first magnet block 402. During this process, the clamping block 407 squeezes the top block 405 and reversely acts on the top block 405 under the action of the return spring 404, so that the top block 405 is clamped in the clamping groove opened on the clamping block 407, thereby fixing the support rod 3 and the main rod 2 together and saving the folding and unfolding space.
