Embodiment 1

[0032] A steel wire rope for concrete prefabricated high-strength metal connectors, comprising steel wire strands 2 twisted into strands by multi-layer steel wires 21 and a mandrel 1, a set number of said steel wire strands 2 are twisted around the mandrel 1 into strands Spiral; the material of the mandrel 1 is a high-plasticity metal material, and the cross-section of the mandrel 1 is not less than one-seventh of the cross-section of the entire steel wire rope.

[0033] Specifically, the elongation of the high-plasticity metal material is not less than 30%, and its elastic modulus is much smaller than that of the steel wire twist, which makes the mandrel already produce a great deal of tension before the steel wire twist undergoes plastic deformation. Plastic deformation, when the mandrel produces plastic deformation, the steel wire rope in the bent part can maintain the bent state. Such a structure not only meets the strength requirements of the steel wire rope during the ho...

Embodiment 2

[0037] The use environment of concrete prefabricated parts is often outdoors, so the steel wire rope of the concrete prefabricated high-strength metal connector is also in the outdoor harsh environment for a long time, so there will be corrosion of the steel wire rope. In addition, during the hoisting process, the steel wire of the steel wire rope Wear and tear will also occur between them, which will affect the service life. For this reason, this embodiment also includes hemp core or cotton core 22 on the basis of embodiment one, and the hemp core or cotton core is twisted in each steel wire strand twist 2, so that in the steel wire rope The hemp core or cotton core 22 can absorb grease during the oiling process, and the steel wire stretching will squeeze out the grease adsorbed in the hemp core or cotton core 22 during use to protect and lubricate the steel wire.

Embodiment 3

[0039] As another embodiment of Embodiment 2, its difference from Embodiment 2 is that the hemp core or cotton core 22 is parallel to the mandrel 1 and is close to the outer peripheral surface of the mandrel 1, thus solving the problems of steel wire protection and lubrication. Basically, the twisting process of the steel wire rope can be simplified.

[0040] The production method of the steel wire rope for the concrete prefabricated high-strength metal connector of the present application comprises the following steps:

[0041] S1: Purchasing semi-finished steel wire blanks and mandrel blanks from enterprises that meet national standards.

[0042] : First, the steel wire blank and the mandrel blank are pickled respectively, dried after pickling, and then drawn separately; specifically, the dried steel wire blank and the mandrel blank are drawn by a wire drawing machine, In order to increase lubrication and reduce wear during the drawing process, wire drawing powder and sapon...

Abstract

The invention discloses a steel wire rope used for a concrete precast high-intensity metal connection element, and a production method for the steel wire rope. The steel wire rope comprises steel wiretwisted strands and a core shaft, wherein a set quantity of steel wire twisted strands is twisted into a spiral form by taking the core shaft as the center; the material of the core shaft is a high-plasticity metal material; and in addition, the area of the cross section of the core shaft is not smaller than 1 / 7 of the area of the cross section of the whole steel wire rope. In addition, the invention also discloses the production method for the steel wire rope. The high-plasticity metal material is taken as the core shaft, in addition, the area of the cross section of the core shaft is not smaller than 1 / 7 of the area of the cross section of the whole steel wire rope, and therefore, the steel wire rope can keep a bending state after the steel wire rope is bent so as to be convenient ininstallation and use.

Description

technical field [0001] The invention belongs to the technical field of steel wire ropes, and in particular relates to a steel wire rope for concrete prefabricated high-strength metal connectors and a production method thereof. Background technique [0002] During the construction process, it is often necessary to place the metal embedded parts at a predetermined position before pouring concrete according to the functional requirements of the building. After pouring concrete, it is fixed in the concrete, and the exposed part is used for connection or hoisting. It is more common in industrial buildings and workshops, where equipment needs to be installed. [0003] Existing prefabrication (embedded parts) is often fixed after the concrete is poured, and cannot be hidden, so that the part exposed to the outside of the concrete will greatly affect the appearance when it is not in use, and the exposed part It may even cause unintended harm to others. [0004] For this purpose, t...
