A cable-suspended roof structure with self-balancing horizontal force

Abstract

The present invention discloses a cable-suspended roof structure with self-balancing horizontal force, which includes a roof, frame beams, multiple frame columns, multiple pairs of masts, cables, suspender bars, diagonal bracing bars and inter-column bracings. Compared with the prior art, in the present invention, the lower end of the diagonal bracing bar is connected to the frame beam, and the upper end of the diagonal bracing bar is connected to the upper end of the mast. Thus, the horizontal component force exerted by the cable on the upper end of the mast is transmitted to the lower structure through the diagonal bracing bar, and self-balanced by the lower structure members, forming a cable-suspended roof structure with self-balancing horizontal force. In this way, there is no need to separately provide an additional structure and its foundation for balancing the horizontal force of the cable externally, reducing the cost and saving space.

Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and particularly to a suspension cable-hung roof structure with self-balanced horizontal forces. Background Art

[0002] In long-span roof structure systems such as suspension cable structures and cable-stayed structures that use tension members to bear external loads, the steel cables as tension members are connected to the upper end of the mast or anchored to the foundation, generating horizontal forces and upward vertical forces at the upper end of the mast or the foundation.

[0003] In construction engineering, roof structures such as trusses, space grids or latticed shells can be combined with steel cables to form a suspension cable-hung roof structure, as shown in Figure 1 shown. Figure 1 The internal force of the suspension cable is balanced by the mast and the back cable, and the horizontal component of the internal force of the suspension cable is transmitted to the foundation by the back cable. In order to balance the inward horizontal force exerted by the suspension cable on the mast, usually one or more outwardly pulled back cables are provided at the upper end of the mast to balance the inward horizontal force received by the mast. However, due to the uplift force and horizontal force on the back cable foundation, the cost of the back cable foundation is high, increasing the project cost; on the other hand, due to the addition of the back cable, extra space is occupied.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] The object of the present invention is to provide a suspension cable hanging roof structure with self-balanced horizontal force, which realizes balance through the interaction of forces among various components inside the structure.

[0026] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] As Figure 2-3 shown, this embodiment provides a suspension cable hanging roof structure with self-balanced horizontal force, which includes a roof 1, a frame beam 4, frame columns, multiple pairs of masts 2, suspension cables 8, suspender bars 9, diagonal bracing bars 3 and inter-column bracings 7. The frame columns include frame corner columns 5 with their upper ends fixed to the corners of the roof 1 and frame side columns 6 with their upper ends fixed to the sides of the roof 1. Among them, the frame-bracing structure composed of the frame beam 4, frame corner columns 5, frame side columns 6 and inter-column bracings 7 serves as the lower structure.

[0028] The frame beam 4 is fixedly connected to the roof 1; the upper ends of the supporting columns are fixedly connected to the edges of the roof 1, and the frame columns are used to support the roof 1; the lower end of each mast 2 is hinged to the upper end of a frame corner column; the upper ends of each pair of masts 2 are connected by a suspension cable 8; the upper end of the suspender bar 9 is fixed to the suspension cable 8, and the lower end of the suspender bar 9 is fixedly connected to the roof 1; one end of the diagonal bracing bar 3 is fixedly connected to the frame beam 4, and the other end of the diagonal bracing bar 3 is fixedly connected to the upper end of the mast 2; the inter-column bracing 7 is used to connect two adjacent frame side columns. In this embodiment, the masts 2 and diagonal bracing bars 3 are preferably spindle-shaped lattice columns or spindle-shaped solid-web columns.

[0029] During use, the edges of the roof 1 are supported by the frame columns, and the middle part of the roof 1 is lifted by the suspender bars 9 to reduce the designed span of the roof 1. The suspension cable 8 will exert an inward horizontal component force on the mast 2, and this horizontal component force is offset by the horizontal component force of the supporting force of the diagonal bracing bar 3 on the mast 2, so as to transfer the horizontal force generated by the suspension cable 8 to the lower structure, and the horizontal force forms a self-balanced state inside the lower structure. The inter-column bracing 7 can improve the structural stability, lateral stiffness and facilitate the force transfer.

[0030] It should be noted that the shape of the roof 1 can be a circular grid, a square grid, a regular polygon grid, etc., and those skilled in the art can select according to actual needs. In this embodiment, the roof 1 is preferably a square grid structure. The frame columns include frame side columns 6 and four frame corner columns 5. The four frame corner columns 5 are respectively fixed at the four corners of the roof 1. The lower ends of the four masts 2 are respectively hinged to the upper ends of the four frame corner columns 5, and the side columns 6 are fixed on the four frame beams 4 of the roof 1.
