[0024] Embodiment. This embodiment aims to provide a portable and weld-free storage bracket for prestressed steel strands. Its main functions are reflected in that it can be disassembled into loose parts for placement during transportation and idle time, effectively reducing the occupied space, and being disassembled into loose parts for short-distance manual transfer at the use site, reducing the weight of each transfer.

[0025] Refer to Figure 1 and Figure 2 , including: a pair of vertical frames, a cross-shaped frame 6 and a connecting arm 7. Among them, the upper cross beam 1, the lower cross beam 2 and the vertical beam 3 are all I-beams. Each of the two vertical frames includes: an upper cross beam 1 and a lower cross beam 2. A pair of vertical beams 3 are provided between the upper cross beam 1 and the lower cross beam 2. The two vertical beams 3 are distributed left and right, and the upper and lower ends of the two vertical beams 3 are respectively in close contact with the flanges of the upper cross beam 1 and the lower cross beam 2. A pair of freely rotatable wire wheels 4 are provided between the two vertical beams 3. A circular hole 5 for the steel strand to pass through is just formed between the two wire wheels 4. A pair of cross-shaped frames 6 are also provided between the two vertical beams 3. The cross-shaped frame 6 is welded by four vertically intersecting threaded steel bars. The circular hole 5 is located in the center of the cross-shaped frame 6.

[0026] Refer to Figure 2, at both ends of the top of the two cross-shaped frames 6 pass through the wing plates of the corresponding upper cross beam 1 and are fastened by bolts. At both ends of the bottom of the two cross-shaped frames 6 pass through the wing plates of the corresponding lower cross beam 2 and are fastened by bolts. At both ends of the two sides of the two cross-shaped frames 6 pass through the wing plates of the corresponding vertical beam 3 and are fastened by bolts. At the same time, the inner wing plate of the vertical beam 3 is closely attached to the side ribbed steel of the adjacent cross-shaped beam, so as to fasten the vertical beam 3 together, and the vertical beam 3 is supported between the upper cross beam 1 and the lower cross beam 2.

[0027] A fixing frame is installed in the center of the cross-shaped frame 6. The fixing frame includes: an outer ring rib 8, an inner ring rib 9 and a connecting rib 10. The outer ring rib 8 and the inner ring rib 9 are connected into one body by multiple connecting ribs 10. One end of the connecting rib 10 is welded and butt-jointed with the outer side of the inner ring rib 9. The other end head of the connecting rib 10 is T-shaped, so that this end is welded to the side ribbed steel of the two cross-shaped frames 6 at the same time; the two wire wheels 4 forming the round hole 5 are rotatably installed in the annular opening of the inner ring rib 9 and are symmetric up and down, and the rotation direction of the wire wheel 4 is consistent with the axial direction of the connecting arm 7 to correctly guide the steel strand. Among them, positioning plates for installing the wire wheels 4 are welded up and down in the annular opening of the inner ring rib 9.

[0028] The connecting arm 7 is horizontally arranged between the two upright frames to connect the two upright frames into one body through the connecting arm 7. At least four connecting arms 7 are provided. The four connecting arms 7 are distributed corresponding to the ends of the upper cross beam 1 and the lower cross beam 2 to form a retaining wall for fixing the coiling position of the steel strand. Among them, the end of the connecting arm 7 passes through the middle of the web of the corresponding upper cross beam 1 or lower cross beam 2 and is fastened by bolts.

[0029] In this embodiment, a fixed-distance pipe 11 is sleeved outside the connecting arm 7 to limit the distance between the two brackets through the fixed-distance pipe 11, and at the same time, it is beneficial to make the connection between the two upright frames more stable.

[0030] When the bracket needs to be transferred, first separate the two upright frames, then lay down a single upright frame, and then separate the upper cross beam 1 and the lower cross beam 2 from the cross-shaped frame 6. Because there is prestress applied by the wing plates of the upper cross beam 1 and the lower cross beam 2 at the end of the vertical beam 3, it is difficult to take out the vertical beam 3. Finally, separate the vertical beam 3 from the cross-shaped frame 6 to transfer the single loose parts.

[0031] The bracket provided by this embodiment can be quickly assembled, and can be disassembled into loose parts for placement during transportation and idle time, effectively reducing the occupied space, providing enough placement space for other equipment or items, and at the same time, it can also be directly disassembled and transferred at a short distance at the use site, minimizing the weight of a single transfer as much as possible, and greatly reducing the labor intensity of workers.

[0032] It can be understood that the above description is only exemplary, and the embodiments of the present application do not limit this.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model are within the scope of protection of the pending claims of the present utility model.
