It needs to install a huge anchor body on the anchor body at the tension anchor end, and reserve a large space behind the anchor body end for tensioning and pretensioning, which has high requirements on the anchor body structure and is not easy to install
[0005] At present, there are usually no special temporary wind-resistant cable anchors on large-scale structural buildings, and it is impossible to reserve space on the components for the tension of the cables. Therefore, there is no ideal method for large-tonnage wind resistance. solve

Embodiment Construction
[0022] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0023] Such as figure 1 As shown, the adjustable cable wind cable provided by the present invention is mainly composed of a prestressed cable, a cable fixing device, a preload adjusting sleeve 11 and a connector arranged in the cable, and a reaction force set at the lower part of the cable. The tensioning device constitutes. The two ends of the cable body 7 of the prestressed cable are the upper anchor head 5 and the lower anchor head 6 respectively. . The two ends of the prestressed cable are equipped with cable fixing devices respectively. The cable fixing device is a pin-hole bolt anchor device. The two ends of the prestressed cable pass through the pin-hole bolt anchor device to form a firm connection with the building structure. The bolt-type anchoring device is mainly composed of upper ear fork 2 and lower ear fork 3, and lug plate 1 and pin shaft 4 respecti...

The invention provides an adjustable cable wind cable for large-scale structure buildings against wind and its installation method. The cable wind cable at least includes a prestressed cable and a cable fixing device. They are the upper anchor head and the lower anchor head respectively. The two ends of the prestressed cable are equipped with cable fixing devices respectively. , The lower part of the cable is equipped with a counter force tensioning device. The cable wind cable can be installed by fixing both ends and tensioning the middle. It has the advantages of large force, high strength and low elasticity, and can meet the wind resistance requirements of large tonnage and low deformation.
Description
technical field [0001] The invention relates to an adjustable wind cable used for wind resistance of a large-scale structure building and an installation method thereof, belonging to the technical field of fixed buildings. Background technique [0002] During the construction process of large buildings such as bridges, the structural force is different from the operating state. The structure is high in height, large in size, and subject to strong wind load. It is often necessary to install cable wind cables to ensure the stability and safety of the structure. According to the magnitude of the wind load on the component, the wind-resistant steel wire rope or steel strand is conventionally used as the wind-resistant steel cable. These two methods have the following disadvantages: [0003] First, the wind-resistant steel cable is less stressed, and it is conventional to perform temporary wind-resistant stabilization for small components. And it adopts chain hoist or winch to c...
