Description
Technical Field
The utility model belongs to the technical field of building engineering, especially, relate to a cable clamp and two-way quadrature cable net.
Background
The cable net structure is a main structure of a roof and is a net-shaped flexible steel structure consisting of two-way steel cables (wind cables and bearing cables). The bidirectional is two directions, taking a bidirectional orthogonal cable net as an example, the bidirectional is that the cables in the two directions are orthogonal to each other; besides the bidirectional orthogonal cable net, the cable net also has a parallel double-cable system, namely two cables which are parallel to each other are arranged at the same axial position. When the double-cable system works, the wind-catching cables are arranged on the upper surface, the wind-catching cables exert force downwards after prestress is exerted, the bearing cables are arranged under the lower surface, the bearing cables exert force upwards after the prestress is exerted, the upward and downward actions enable the cable net to be balanced in situ, when the cable net structure bears downward load, the bearing cables play a main role in resisting downward deformation, and when the cable net structure bears upward load such as wind suction, the wind-resisting cables play a main role in resisting upward deformation. The two-way steel cable has opposite curvature, and the steel cable is a one-way stressed component only bearing tension and can play a role in supporting the structure only when tension is applied; the cable is fixed to a peripheral rigid or flexible support member for receiving the action of the cable tension.
In order to avoid the problem that main cable strands in a cable net structure slide when being contracted and deformed, the main cable strands are often clamped by cable clamps in the construction process, the conventional cable clamps are mostly composed of two cast steel semicircular components, and during installation, each pair of semicircular cable clamps are firstly installed on the main cable and then are butted by high-strength bolts to form a cable clamp node. The cable clamp is suitable for semi-parallel steel wire bundle inhaul cables or high-vanadium cables (a cable body is formed by spirally twisting at least two layers of steel wires around a central round steel wire, a combined strand or a parallel twisted strand, and the surfaces of the steel wires are provided with zinc-aluminum-5% rare earth alloy coating, so that the cable clamp has good corrosion resistance, and the high-vanadium cables are increasingly selected to replace the original semi-parallel steel wire bundle inhaul cables in the buildings at home and abroad at present).
However, with the improvement of the requirement of people on the performance of the cable net structure, some building roofs such as gymnasium roofs can adopt a high-vanadium closed cable to manufacture the cable net structure, and different from the high-vanadium cable, the periphery of a steel cable of the high-vanadium closed cable adopts non-circular steel wires, such as z-shaped steel wire rings, which are buckled with each other to form a closed cable shell, and the cable shell can prevent water and air from entering the cable body to further cause corrosion inside the cable body, so that the cable net structure has better corrosion resistance; meanwhile, as the z-shaped steel wire (shown in figure 1) is adopted, the outer surface of the inhaul cable is smoother, the smooth surface enables a larger contact area to be formed between the closed cable net structure and the cable clamp, and when the inhaul cable bears the same sliding force, the closed inhaul cable clamp needs a smaller clamping area because the closed inhaul cable clamp can bear larger uniformly distributed pressure; in addition, because the site is paved with the guy cable during the site construction, and the heavy equipment such as a crane is inconvenient to move, the structure of the existing cable clamp needs to be optimized in order to facilitate the workers to move and install the cable clamp, so as to facilitate the site construction. In addition, some buildings need to design a double-layer roof system, namely, a suspended ceiling is arranged under a conventional building roof, or an owner needs to provide a requirement that an uncertain hanging object needs to be added under a roof in a use stage, so that a cable clamp capable of meeting a novel roof system needs to be provided urgently.
