More and more cable support structures are used for glass curtain walls, especially one-way cable curtain walls and single-layer cable net curtain walls, which are widely used because of their simple structure and transparency. With the development of technology, the span of the cable is getting larger and larger, and the cable diameter is getting thicker. Under different changes in temperature and wind load, the cable will stretch and relax; when the load exceeds the maximum allowable load, the cable will be broken, which greatly affects the safe use of the cable curtain wall. influences.

In the past, either only realized the anti-loosening function or only the overload function. Our company's patented product-cable anti-loosing overload protection device (patent number: ZL 2014 2 0036430.4) integrates cable anti-loosening device and cable overload protection The advantages of the device have the above two functions at the same time.

The cable anti-loosening and overload protection device, such as the cable applying 20 tons of pre-tightening force, when the internal force of the cable exceeds the design value, the neck is broken, the spring continues to work under the pressure of 25 tons, so that the curtain wall can continue to be used safely; When slack due to various reasons, the extension of the spring can keep the cable under 15 tons of pre-tightening force and continue to work, ensuring the safe use of the curtain wall. The structure can be used on the outside of the connection point between the cable and the building structure; it can also be used on the inside of the connection point between the cable and the building structure. The cable anti-loosening overload protection device can be used in combination or separately.

For the cable curtain wall made between two buildings, due to the inconsistency of the settlement of the two buildings, the two sides of the cable curtain wall tilt outward (the red cable is required in the figure), the cable tension is too tight, and the tension increases; or the cable The two sides of the curtain wall tilt inward (as shown in the green line), the supporting distance of the cable becomes smaller and slack occurs. In this case, the use of a cable anti-loosening overload protection device can solve this unpredictable problem that changes at any time.

The cable curtain wall support cable is fixed between the layers. When the gravity of a layer increases, the main structure of the layer will deform downward, causing the cable at the structure to tighten and loosen.

During the use of the building structure, the gravitational action between each layer changes differently, and structural deformation occurs, and the force state of each section of the cable will change. Therefore, the use of a cable anti-loosening overload protection device can solve this unpredictable problem that changes at any time.
