[0016] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention will now be further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the relevant components of the present invention.

[0017] According to the technical solution of the present invention, without changing the essential spirit of the present invention, those skilled in the art may propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are merely illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0018] The technical solution of the present utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 and Figure 3 The figure shows an eccentric steel cable sleeve device for a cable curtain wall, comprising a prefabricated component 1, cables 2, and a steel sleeve 3. Prefabricated component 1 is made of concrete and installed at the bottom of the curtain wall. A sleeve 11 with flanges at both ends is installed within prefabricated component 1. Sleeve 11 is embedded in prefabricated component 1 during prefabrication.

[0020] A steel sleeve 3 is installed at the top of the sleeve 11. This serves as a guide for the cable 2 and features an eccentric wire hole 33. A tensioner 22 is installed at the bottom of the sleeve 11 to tighten the cable 2. The lower end of the cable 2 is connected to the tensioner 22, while the upper end of the cable 2 passes through the wire hole 33 and extends upward to connect to the top lug of the curtain wall. This completes the installation of a single vertical cable.

[0021] See also Figure 2 and Figure 3 The steel sleeve 3 includes a flange 31 and an eccentric sleeve 32. The flange 31 and the eccentric sleeve 32 are fixedly connected. The wire hole 33 is located on one side of the central axis of the flange 31 and the eccentric sleeve 32, playing an eccentric role and cooperating with the ear plate and the embedded sleeve. The flange 31 is located on the upper flange surface of the sleeve 11 and has an embedded structure. The eccentric sleeve 32 is located in the upper inner cavity of the sleeve 11 and is completely accommodated by the inner cavity of the sleeve 11.

[0022] As a preferred approach, in one embodiment, the wire hole 33 is parallel to the central axis of the flange 31 and the eccentric sleeve 32, which can better tighten the zipper 2 through the tensioner 22. A convex surface 34 is provided on the top of the flange 31. The convex surface 34 is higher than the surrounding surface at the center of the flange 31. When rain or liquid encounters the ground, the central portion or the position of the wire hole 33 is raised, allowing the liquid to flow outward, thereby protecting the wire hole 33 and preventing rust.

[0023] As a preferred manner, in one embodiment, the inner wall of the wire hole 33 is a symmetrical parabolic structure, which can reduce friction and prevent the contact surface from causing wear of the cable 2. In addition, to reduce friction, a layer of lubricant, such as butter, engine oil, etc., can be applied to the wire hole 33.

[0024] During implementation, at least one inner support plate 14 can be fixed on the outer wall of the sleeve 11, and generally two are welded and fixed. The inner support plate 14 is a circular ring structure. During prefabrication, the inner support plate 14 is located inside the prefabricated part 1. By setting the inner support plate 14, the sleeve 11 can be retained more stably inside the prefabricated part 1.

[0025] A ground layer 12 is laid on the top of the prefabricated part 1, which makes the top of the prefabricated part 1 neater and covers the steel sleeve 3. Glass 13 is installed on the side of the ground layer 12 close to the cable 2. The glass 13 can be set along the cable 2 to provide good light transmission effect for the curtain wall.

[0026] During manufacturing, the steel sleeve 3 is made of Q355B and is processed by a CNC five-axis machine tool. The cross-section of the middle wire hole 33 is processed in a parabolic shape, and the steel sleeve 3 is in contact with the vertical cable 2 in the form of a point. Grease is added during installation to reduce the friction between the steel sleeve 3 and the cable 2.

[0027] In order to solve the problem that the embedded ear plate and the embedded sleeve are not in concentric circles, the utility model designs a steel drum cable sleeve eccentric device according to the actual construction conditions on site, which can effectively solve the actual deviation of the steel structure of the main embedded parts on site, meet the prestressed tensioning of the cable body 2, and meet the use function of the cable curtain wall building.

[0028] In general, it solves the difficult working conditions of cable installation and tensioning of super-large flat cable curtain wall; meets the appearance effect of cable curtain wall architectural design, and ensures that the cable body is vertical within the visible range; solves the deviation working conditions of the top ear plate and the bottom embedded steel structure sleeve on site, and avoids rework due to the steel structure accuracy not meeting the requirements; the interior of the steel sleeve 3 adopts a parabolic structure, which can effectively protect the strength of the cable body itself, and the addition of butter technology effectively solves the installation friction problem.

[0029] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
