Problems solved by technology

Among them, the planar network frame and cylindrical reticulated shell are rigid structures, which have obvious disadvantages in terms of self-weight and steel consumption compared with flexible structures, and the workload of component manufacturing is large, the construction period is long, and the cost of temporary measures is high; while ordinary The cable net structure also has high requirements for the tensioning of the cable pretension. The construction of tensioning requires a lot of manpower and equipment resources, and it also needs to be completed by a professional construction team.
In addition, due to the light weight of the flexible cable structure, the ordinary cable net structure is more sensitive to the wind load, and the structural design is more difficult than the rigid structure.

Embodiment Construction

[0019] Attached below Figure 1~6 , to describe the implementation of the present invention in detail.

[0020] Such as figure 1 , 2 As shown, a self-balancing cable-net structure capable of relieving wind loads includes the following components:

[0021] 1——steel arch in the middle;

[0022] 2——end steel arch;

[0023] 3——longitudinal ground beam;

[0024] 4——horizontal ground beam;

[0025] 5 - load-bearing cable;

[0026] 6——stabilizing cable;

[0027] 7 - counterweight;

[0028] Such as figure 1 , 2 , 3, a self-balancing cable net structure that can moderate wind loads consists of a central steel arch 1, an end steel arch 2, a longitudinal ground beam 3, a transverse ground beam 4, load-bearing cables 5, stabilizing cables 6 and counterweights 7 composition. The middle steel arch 1 is set in the middle of the structure longitudinally, and can be set in single or multiple lanes according to the actual structure length; the end steel arch 2 is installed obliquely...

Abstract

The invention discloses a self-balancing cable net structure capable of moderating the wind load, and belongs to the technical field of structural engineering. The self-balancing cable net structure comprises a middle part steel arch, an end part steel arch, a longitudinal grade beam, a transverse grade beam, a bearing cable, a stabilizing cable and balance weights. The middle part steel arch is arranged in the middle of the longitudinal direction of the structure, and can be arranged by selecting a single arch or a plurality of arches according to the length of the practical structure; the end part steel arch is obliquely arranged at the end of the structure; the longitudinal grade beam is arranged under arch feet of the end part steel arch and the middle part steel arch in the longitudinal direction of the structure, and serves as an anchoring point of the arch feet of the end part steel arch and the middle part steel arch; the transverse grade beam is transversally connected to the position between the arch feet of the end part steel arch and the middle part steel arch, and achieves the effect of balancing thrust of the arch feet; the bearing cable is arranged in the longitudinal direction of the structure in a length through mode; the stabilizing cable is transversally arranged along the structure, and the end of the stabilizing cable is anchored into the longitudinal grade beam, and connected with the bearing cable to form a hyperbolic paraboloid cable net to bear the wind load; and the balance weights are hung at the two ends of the bearing cable, and hidden below the ground surface. The structure is a novel structural system being efficient and economic.

Description

technical field [0001] The invention relates to a self-balancing cable net structure capable of alleviating wind load, and belongs to the technical field of structural engineering. Background technique [0002] In recent years, due to the development of my country's electric power industry and environmental protection requirements, the traditional coal bulk storage method has been replaced by closed storage, and dry coal sheds have been extensively constructed, and the span is getting larger and larger. At present, the common structural forms of dry coal sheds mainly include planar grids, cylindrical reticulated shells, and common cable-net structures. Among them, the planar network frame and cylindrical reticulated shell are rigid structures, which have obvious disadvantages in self-weight and steel consumption compared with flexible structures, and the workload of component manufacturing is large, the construction period is long, and the cost of temporary measures is high;...
