Background
In a large span roof structure system of a suspension cable structure, a cable stayed structure, etc., which uses tension members to bear external load, a cable as a tension member is connected to the upper end of a mast or anchored to a foundation, and horizontal force and upward vertical force are generated at the upper end of the mast or at the foundation.
In the construction engineering, a roof structure such as a truss, a net rack or a net shell and the like can be combined with a steel rope to form a roof structure hung by a suspension rope, as shown in fig. 1. The internal force of the suspension cable of fig. 1 is balanced by the mast and the back cable, and the horizontal component of the internal force of the suspension cable is transferred to the foundation by the back cable. In order to balance the inward horizontal force exerted by the suspension cable on the mast, one or more outwardly pulled back cables are typically provided at the upper end of the mast to balance the inward horizontal force exerted by the mast. However, the back cable foundation is high in cost due to the pulling force and horizontal force of the back cable foundation, and the engineering cost is increased, and on the other hand, the additional space is occupied due to the addition of the back cable.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention aims to provide a horizontal force self-balancing suspension cable hanging roof structure, which realizes balance through the interaction of forces among all parts in the structure.
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
As shown in fig. 2-3, the present embodiment provides a horizontal force self-balancing suspension cable suspended roof structure, which comprises a roof 1, a frame beam 4, frame columns, a plurality of pairs of masts 2, suspension cables 8, a suspension rod 9, diagonal braces 3 and inter-column supports 7, wherein the frame columns comprise frame corner columns 5 with upper ends fixed at corners of the roof 1 and frame side columns 6 with upper ends fixed at edges of the roof 1. Wherein the frame-supporting structure consisting of the frame beams 4, the frame corner posts 5, the frame side posts 6 and the inter-post supports 7 is used as a lower structure.
The frame beam 4 is fixedly connected with the roof 1, the upper ends of the support columns are fixedly connected with the edge of the roof 1, the frame columns are used for supporting the roof 1, the lower end of each mast 2 is hinged with the upper end of one frame corner column, the upper ends of each pair of masts 2 are connected through a suspension rope 8, the upper ends of suspension rods 9 are fixed on the suspension ropes 8, the lower ends of the suspension rods 9 are fixedly connected with the roof 1, one ends of the diagonal braces 3 are fixedly connected with the frame beam 4, the other ends of the diagonal braces 3 are fixedly connected with the upper ends of the masts 2, and the inter-column supports 7 are used for connecting two adjacent frame side columns.
