Description

Technical Field

[0001] This utility model relates to the field of steel reinforcement cage forming technology, and in particular to an adjustable spacing prefabricated component for steel reinforcement cage fabrication. Background Technology

[0002] The steel reinforcement cage plays a vital role in concrete structures in resisting tension, shear, and cracking. Its processing and forming quality directly affects the uniformity of the concrete cover, the corrosion resistance of the steel reinforcement, and the overall stability of the structure.

[0003] Traditional manual binding and on-site welding methods are not only inefficient, but also prone to problems such as uneven rebar spacing and insufficient protective layer thickness due to human error, leading to durability issues such as rebar corrosion and concrete cracking. These problems can seriously affect the safety and service life of large infrastructure projects, including bridges, high-rise buildings, and water conservancy projects. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose an adjustable spacing prefabricated component for the fabrication of steel reinforcement cages, which can improve the shaping efficiency of steel reinforcement cages, is suitable for the rapid positioning of steel bars of different diameters, facilitates the fixed-point binding of binding wires, improves binding efficiency, reduces the labor intensity of workers, further enhances the forming stability of steel reinforcement cages, meets the diameter adjustment of steel reinforcement cages, and maintains equal spacing between adjacent steel bars for shrinkage adjustment.

[0006] To achieve the above objectives, this utility model proposes an adjustable-spacing precast component for the fabrication of a steel reinforcement cage, comprising a positioning tube, multiple support blocks, multiple sets of adjustable positioning components, and multiple limiting mechanisms. The multiple support blocks are movably connected to the positioning tube via the multiple sets of adjustable positioning components, and the multiple limiting mechanisms are respectively disposed on the multiple support blocks. Each adjustable positioning component includes a positioning ring, two symmetrically arranged adjusting rings, and two symmetrically arranged connecting rods. The positioning ring is disposed on the positioning tube, the two symmetrically arranged adjusting rings are disposed on the positioning tube and threadedly connected to the positioning tube, and the two symmetrically arranged connecting rods are pivotally connected between the adjusting rings and the positioning rings.

[0007] This utility model discloses an adjustable-spacing precast component for the fabrication of steel reinforcement cages. By limiting the steel bars in the support block through a limiting mechanism, the steel bars are quickly positioned, promoting the formation of the steel reinforcement cage. The adjustable positioning component allows for equal spacing adjustment of the diameter of the positioned steel bars, effectively reducing the labor intensity of workers and improving the safety and service life of the steel reinforcement cage.

[0008] In addition, the adjustable-spacing precast component for steel reinforcement cage fabrication proposed above according to this utility model may also have the following additional technical features:

[0009] Specifically, the limiting mechanism includes two symmetrically arranged locking rods, a positioning plate, and an adjusting stud. The two symmetrically arranged locking rods are movably connected to the support block and pass through the support block. The positioning rod is disposed on the two symmetrically distributed locking rods. The adjusting stud is disposed on the support block, passes through the positioning plate, and is threadedly connected to the positioning plate.

[0010] Specifically, the support block has a limit groove.

[0011] Specifically, the locking rod is arranged in an inverted U-shape and is positioned opposite to the limiting groove.

[0012] Specifically, an elastic element is provided between the two symmetrically arranged adjusting rings and the positioning ring.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The adjustable-spacing precast component for steel reinforcement cage fabrication according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0021] like Figures 1-3 As shown, the adjustable spacing prefabricated component for making steel reinforcement cages according to this utility model embodiment may include a positioning tube 1, multiple support blocks 2, multiple sets of adjustable positioning components 3 and multiple limiting mechanisms 4.

[0022] Among them, multiple support blocks 2 are movably connected to the positioning tube 1 through multiple sets of adjustable positioning components 3, and multiple limiting mechanisms 4 are respectively set on multiple support blocks 2.

[0023] It should be noted that multiple sets of adjustable positioning components 3 can simultaneously and stably support and adjust multiple support blocks 2, enabling the support blocks 2 to move radially along the positioning tube 1.

[0024] The adjustable positioning component 3 includes a positioning ring 31, two symmetrically arranged adjusting rings 32, and two symmetrically arranged connecting rods 33.

[0025] The positioning ring 31 is mounted on the positioning tube 1, and two symmetrically arranged adjusting rings 32 are mounted on the positioning tube 1 and threadedly connected to the positioning tube 1. Two symmetrically arranged connecting rods 33 are pivotally connected between the adjusting rings 32 and the positioning rings 31, respectively.

[0026] It should be noted that the outer wall of the positioning tube 1 is provided with positive and negative threads. When the positioning tube 1 is rotated, the two symmetrically arranged adjusting rings 32 move synchronously to achieve synchronous support on both sides of the support block 2 and maintain the position of the support block 2.

[0027] Specifically, in actual use, relevant personnel insert each reinforcing bar into the limiting mechanism 4 to form a stable columnar reinforcing bar skeleton, which can improve the forming efficiency of the reinforcing bar skeleton. At the same time, at the contact position between the reinforcing bar and the locking rod 41, the reinforcing bar is further bound by binding wire, which facilitates the positioning of the binding wire, improves the binding efficiency, and further enhances the forming stability of the reinforcing bar skeleton. At least two of these devices are set at both ends of the reinforcing bar skeleton. In the initial state, each support block 2 is close to the outer circumference of the positioning tube 1. When the positioning tube 1 is rotated, the two symmetrically arranged adjusting rings 32 move in opposite directions along the axial direction of the positioning tube 1. At the same time, the two symmetrically arranged connecting rods 33 rotate, pushing the support block 2 in the middle section of the positioning tube 1 and moving it radially along the positioning tube 1 to realize the diameter adjustment of the reinforcing bar skeleton.

[0028] In one embodiment of this utility model, such as Figure 3 As shown, the limiting mechanism 4 includes two symmetrically arranged locking rods 41, a positioning plate 42, and an adjusting stud 43.

[0029] Two symmetrically arranged locking rods 41 are movably connected to the support block 2 and pass through the support block 2. A positioning rod is set on the two symmetrically distributed locking rods 41. An adjusting stud 43 is set on the support block 2, passes through the positioning plate 42, and is threadedly connected to the positioning plate 42.

[0030] It should be noted that the adjusting stud 43 is rotatably connected to the bottom of the support block 2. Through the threaded connection, the positioning plate 42 is driven to move up and down for adjustment, while the two symmetrically arranged locking rods 41 slide within the support block 2 to fix the reinforcing bar.

[0031] In one embodiment of this utility model, such as Figure 3 As shown, a limit groove 21 is opened on the support block 2.

[0032] It should be noted that the limiting groove 21 is V-shaped, which can fit with the outer wall of steel bars of different diameters, thereby enhancing the limiting effect on the steel bars.

[0033] In one embodiment of this utility model, such as Figure 3 As shown, the locking rod 41 is arranged in an inverted U-shape and is positioned opposite to the limiting groove 21.

[0034] It should be noted that the bent part of the locking rod 41, together with the limiting groove 21, is fastened to the outside of the reinforcing bar, further improving the fixing effect of the reinforcing bar.

[0035] In one embodiment of this utility model, such as Figure 1 As shown, an elastic element is provided between the two symmetrically arranged adjusting rings 32 and the positioning ring 31.

[0036] It should be noted that the elastic element is a spring, which uses the axial elastic support of the spring to increase the movement stability of the adjusting ring 32, maintain the position of the adjusting ring 32, and reduce the positional movement of the adjusting ring 32 caused by other factors.

[0037] In summary, the adjustable-spacing precast component for steel reinforcement cage fabrication according to this utility model embodiment is suitable for rapid positioning of steel bars of different diameters, reduces the labor intensity of workers, meets the diameter adjustment of the steel reinforcement cage, and maintains equal spacing between adjacent steel bars for shrinkage adjustment.
