Abstract

The invention discloses a closed steel structure of a double-cable-coil spoke arch coal shed. The closed steel structure comprises spoke arch closed steel, a longitudinal coupling beam and an arch reticulated shell, the spoke arch closed steel comprises a steel arch, at least seven prestressed inhaul cables and two cable coils (a) and (b) which are symmetrically arranged on the same horizontal plane along the central axis of the steel arch, the cable coil (a) and the cable coil (b) are connected through the prestressed inhaul cables, and the cable discs (a) and (b) are respectively connected with the steel arch through at least three prestressed cables; and the two closest prestressed inhaul cables of the steel arch and the cable discs (a) and (b) are arranged in a crossed mode, and the two closest prestressed inhaul cables and the second adjacent prestressed inhaul cable on the other cable disc are connected to the same point of the steel arch. According to the closed steel structure of the double-cable-coil spoke arch coal shed, on one hand, the rigidity and the bearing capacity of the steel arch can be greatly improved, and the sensitivity of the steel arch to geometric initial defects is reduced; and on the other hand, the double-cable-disc design can enlarge the indoor space, the requirement of the technology for indoor clearance is easily met, and the structure is more suitable for a large-span coal shed.

Description

technical field

[0001] The invention belongs to the technical field of structural engineering, and in particular relates to a closed steel structure of a double cable tray spoke arch coal shed. Background technique

[0002] With the development of my country's electric power, coal and other industries, as well as the improvement of environmental protection requirements, large-capacity and closed coal sheds have been promoted. Arched steel structures are widely used in closed coal sheds, but their application in long-span spaces is limited due to their sensitivity to initial defects and limited stable bearing capacity. In order to expand the span of the steel arch and improve its stable bearing capacity, the use of spoke steel arches is one of the preferred options. However, because the closed coal shed structure requires high clearance, the single-cable spoke arch limits its space utilization.

[0003] In view of the above problems, it is necessary to design a new type of ...
