Description

Cable adjuster

technical field

The invention relates to the technical field of adjustment devices, in particular to a cable adjuster.

Background technique

In the past ten years, with the development of domestic sports, the demand for large-scale sports buildings has increased sharply. At the same time, due to the development of the domestic economy and the improvement of people's material living standards, more and more attention is paid to the aesthetics of buildings. Traditional architectural forms have been difficult to meet the needs of public aesthetics, so in recent years, cable-tensioned structures have been favored by more and more architects and structural engineers due to their lightness and high efficiency. The tensile structure is different from the traditional pure rigid structure. Due to the zero compression stiffness of the cable, the universality of the tensile structure is much smaller than that of the rigid structure.

In the actual construction process of buildings such as venues, curtain wall cables, roof cable nets, etc. are usually installed after the ring truss construction is completed, and then the curtain wall keel is installed. Among them, the nodes of the roof cable net are provided with cable clips for tightening the main cable strands and connecting the main cable and the curtain wall keel. When the roof cable net is tensioned, the curtain wall cables are passively tensioned, and when the force is small, they are clamped in The cable clip at the cable node relies on the friction between the cable and the cable to resist the unbalanced force, but due to the limited pressure that the cable can withstand per unit length, when the unbalanced force is large, the position of the control point of the cable clip will occur. At the same time, since the construction and installation sequence of the curtain wall keel is often located after the cable tensioning, the construction error caused by the tensioning will cause the control point of the cable clamp to be different from that of the theoretical model. There is a deviation in the theoretical point position, which leads to the problem that the lug cannot be inserted into the lug slot or the pin shaft hole cannot be inserted into the pin shaft in the connection between the cable clip and the curtain wall keel. To solve the problem of the offset of the control point of the cable clamp, a larger friction surface is often required to meet the anti-slip requirements of the cable, and the larger contact surface means a larger volume of the cable clamp, which will undoubtedly increase the production cost; , Due to the need to install glass on the outer curtain wall, there will be a large slip force between the curtain wall keel and the cable, and the conventional cable clips that rely on friction to resist the slip force cannot meet the engineering requirements and affect the aesthetics. If the curtain wall keel can digest the construction errors left over from the previous construction process during construction, it is required that the relative position of the cable clamp node can be adjusted after the cable tensioning is completed, and the internal force of the cable cannot be changed at the same time.
