Abstract

The utility model relates to a cable arch structure, in particular to a novel grounded cable arch structure, which belongs to the field of steel structures. The novel grounded cable arch structure comprises a steel arch, wherein connecting rod groups are uniformly arranged on the lower part of the steel arch, one connecting rod group comprises two connecting rods, the connecting rod groups are supported and fixed through connecting nodes, the connecting nodes are connected in series through a stay rope, and both ends of the stay rope and both ends of the steel arch are tensed. The novel grounded cable arch structure is simple in structure, the supporting property is improved, and safety is improved.

Description

A kind of novel rope arch structure that lands
Technical field
The utility model relates to a kind of rope arch structure, relates in particular to a kind of novel rope arch structure that lands, and belongs to field of steel structure.
Background technology
The steel arch structure of prior art has the good mechanical performance at present; In large span such as bridge, stadiums, exhibitions and transport hub and super-span building, obtained extensive use, its primary structure form has real abdomen formula steel arch, lattice steel arch and rope arch structure three major types.Because real abdomen formula steel arch itself is born moment of flexure, axle power; Its load-carrying efficiency is not high; Generally be applied to the medium and small span structure, but, in longspan structure, also obtained certain application because it has lightly lucid and lively, the succinct penetrating building visual effect and the advantage of indoor free height.Compare with real abdomen formula steel arch, the lattice steel encircles the axle power that moment of flexure is converted into chord member, has bigger structural bearing efficient.And the rope arch structure can effectively improve the integral rigidity and the stability bearing capacity of arch structure through reasonable Arrangement, reduces the whole steel using amount of arch structure.Therefore, for large span and super-span structure, the rope arch structure is even more ideal form of structure.But the rope arch structure is complicated, and trouble is installed, and support strength is low.
The utility model content
The utility model mainly is to solve the deficiency that exists in the prior art, provides a kind of simple in structure, and the good novel rope arch structure that lands of support performance.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of novel rope arch structure that lands; Comprise steel arch, it is one group connection rod set that the bottom of described steel arch evenly is provided with two connecting rods, and described connection rod set is through connected node phase support fixation; Be connected in series mutually through drag-line between described connected node, strain with the two ends of steel arch mutually at the two ends of described drag-line.
Simple in structure, the drag-line support strength is high.
As preferably, described connection rod set and steel arch triangularity cross section.
The utility model provides a kind of novel rope arch structure that lands, and is simple in structure, improves support performance, improves safety.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment 1: as shown in Figure 1; A kind of novel rope arch structure that lands comprises steel arch 1, and it is one group connection rod set that the bottom of described steel arch 1 evenly is provided with two connecting rods 2; Described connection rod set is through connected node 3 phase support fixation; 3 of described connected nodes pass through drag-line 4 and are connected in series mutually, and strain with the two ends of steel arch 1 mutually at the two ends of described drag-line 4, and described connection rod set and steel encircle 1 formation triangular-section.

Claims (2)

1. novel rope arch structure that lands; It is characterized in that: comprise steel arch (1); It is one group connection rod set that the bottom of described steel arch (1) evenly is provided with two connecting rods (2); Described connection rod set is connected in series through drag-line (4) between described connected node (3) through connected node (3) phase support fixation mutually, and strain with the two ends of steel arch (1) mutually at the two ends of described drag-line (4).
