Detailed Description

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings. It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.

As shown in fig. 1, the suspension i-steel cable-stayed cable wire limiting device provided by the embodiment includes a positioning sleeve 1, a clamping piece 2, a stay bar 3, a support plate 4, a support lug 5 and a bolt 6.

The positioning sleeve 1 comprises a bottom wall 12 and top walls 13 which are bent from two ends of the bottom wall 12 and extend in the direction close to each other, so that a containing cavity 11 is formed between the bottom wall 12 and the two top walls 13. The extended ends of the two top walls 13 (i.e. the top of the positioning sleeve 1) are provided with notches 14.

The top wall 13 is provided with the support lug 5. The number of the clamping pieces 2 is two, and the two clamping pieces are arranged oppositely. The bottom of each clamping piece 2 is provided with one support plate 4, the support lugs 5 are arranged at the top of the positioning sleeve 1, the support plates 4 correspond to the support lugs 5 one by one and are hinged with each other, and the clamping pieces 2 can rotate along the hinged shafts. As shown in fig. 3, the support lugs 5 and the support plates 4 may be arranged in a plurality, such as two (pairs), in the length direction of the positioning sleeve 1.

The stay bar 3 is horizontally arranged on the outer side wall of the support plate 4. Specifically, the stay bar 3 is n-shaped, and an n-shaped opening of the stay bar is connected with the clamping piece 2. So as to be able to spread and closely attach the diagonal draw steel wire rope 8, increase the friction force (as shown in fig. 2) and prevent the positioning sleeve 1 from shifting.

The bottom (bottom wall 12) of the locating sleeve 1 is provided with a bolt 6 which extends into the accommodating cavity 11.

As shown in fig. 2 and 3, the utility model also provides an overhanging scaffold, which comprises an overhanging i-steel 7, a diagonal steel wire rope 8 and the overhanging i-steel diagonal steel wire rope limiting device.

During installation, the wing plate at the bottom of the overhanging I-beam 7 is aligned to the position of the cavity 11, the web plate is aligned to the position of the notch 14, then the positioning sleeve 1 slides into the cavity 11 from the side of the positioning sleeve 1, so that the positioning sleeve 1 slides to the proper position of the overhanging I-beam 7 (as shown in fig. 3), and then the bolt 6 at the bottom is fastened to be abutted to the bottom of the wing plate.

Then the clamping pieces 2 on the two sides of the web plate are rotated and attached to the side surface of the web plate. And the limiting plate 10 is used for limiting the inclined pull steel wire rope 8 at the inclined pull direction side of the inclined pull steel wire rope 8, and the limiting plate 10 is arranged at the bottom of the positioning sleeve 1. The limiting plate 10 is L-shaped, the vertical edge of the limiting plate is connected with the bottom wall 12, and the horizontal edge of the limiting plate extends towards the side far away from the inclined pulling direction.

After the cable-stayed steel wire rope 8 revolves from the bottom of the positioning sleeve 1 and the support rod 3, the top of the overhanging I-shaped steel 7 is fixed by a rope clamp 9 and then is anchored on a hanging ring (not shown) of an overhanging scaffold. The inclined steel wire rope 8 is positioned in the L shape of the limiting plate 10.

Once the inclined steel wire rope 8 bears the load transmitted by the overhanging I-shaped steel 7, the inclined steel wire rope 8 is pulled to tightly hold the clamping piece 2, so that friction force is generated between the clamping piece 2 and the web plate, and friction force is also generated between the inclined steel wire rope 8 and the support rod 3, therefore, the horizontal displacement of the inclined steel wire rope 8 and the overhanging I-shaped steel inclined steel wire rope limiting device due to stress is prevented.

In addition, after the construction of the cantilever scaffold is completed, the cantilever I-steel cable-stayed steel wire rope limiting device and the cantilever I-steel can be repeatedly used after being detached, and the cantilever I-steel cannot be damaged in layout due to welding.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
