Description

A double-layer cable structure system combining square and rib-ring grids

technical field

The utility model relates to the technical field of building structures, in particular to a double-layer cable structure system combining square-shaped and rib-ring grids.

Background technique

The prestressed cable structure is composed of flexible cables only in tension and rigid members under tension and compression. It is a large-span structural system with strong spanning ability and good mechanical performance. Because the cable is made of high-strength materials and is in tension during the structural bearing process, there is no problem of component stability and high stress efficiency, so its cross-sectional size is much smaller than that of concrete components and steel components, which can create a light and transparent building. Effect.

Currently, the structures of stadiums such as track and field fields and professional football fields are composed of a stand structure 101, a roof structure 102 and a roof support structure 103 surrounding the central field, as shown in FIG. 1 . The main function of the roof structure 102 is to shade the stands and hang the horse path, lighting and sound equipment, etc. Since the interior of the stadium needs to create a column-free space, and the space above the middle of the stadium is generally open-air, the roof is usually arranged around the field, covering only the stand area, and is constructed by a large-span structure with a large central opening. The shape of the central opening is generally the same as that of the surrounding stands. The inner edge shape matches.

Due to its significant advantages in mechanical performance and architectural effect, prestressed cable structures have been widely used in stadium roof structures. Roof cable structures typically consist of a ring cable 201 near the central opening and a spanwise cable system between the ring cable 201 and the outer boundary 202 . According to the needs of building modeling, the spanwise cable system can adopt the square grid cable net 203, or can adopt the radial cable system 204, as shown in Fig. 2a and Fig. 2b. For the double-layer cable structure, the upper and lower layers can both use the square mesh cable net 203, or both use the radial cable system 204, or the upper layer can use the square mesh cable net 203, and the lower layer can use the radial cable system 204 , or vice versa, as shown in Figure 3a, Figure 3b, Figure 3c, Figure 3d.

When the spanwise cable system between the ring cable and the outer boundary is a square grid, due to the inevitable component force in the spanwise cable system in the tangential direction of the ring cable, there will be a A large unbalanced force is generated at the clip node, which leads to an increase in the volume of the cable clip, and even requires a special balance cable to resist the unbalanced force at the cable clip, which brings difficulties to the structural design and construction, and increases the project cost. In addition, in order to meet the building requirements, additional steel structure canopies 205 may also be arranged inside the area enclosed by the ring cable, as shown in FIG. 4 . This kind of structural arrangement will cause the structure and stress of the connection between the cable structure and the steel structure canopy 205 to be complicated, and it is necessary to install the steel structure canopy 205 separately after the cable structure is tensioned. long and high risk.
