Problems solved by technology

Still taking the 150m×150m roof as an example, the conventional “pseudo-beam space tube truss structure” is adopted, which occupies more than 135,000 to 146,000 cubic meters of building volume, and increases the cost of enclosure materials, which is not conducive to “energy saving and emission reduction”

Embodiment 1

[0028] Example 1. Such as figure 1 , 2 As shown, the grid 1 is formed by a number of x-direction space pipe trusses 2 arranged along the x direction and several y-direction space pipe trusses 3 arranged along the y direction; There are two x-directed prestressed spatial tube trusses 4 along the x direction, and there are two y-directed prestressed spatial tube trusses 5 along the y direction. The two x-directed prestressed spatial tube trusses 4 and the two y-directed prestressed spatial tube The trusses 5 are orthogonal to each other; the prestressed steel cable 6 is arranged on the x-direction prestressed space pipe truss 4 and the y-direction prestressed space pipe truss 5, and the x-direction prestressed space pipe truss 4 and the y-direction prestressed space pipe truss 5. The intersection point of the lower chord is provided with a cable steering support frame 7. There are two support nodes 8 at both ends of the upper chord of each x-direction prestressed space pi...

Abstract

The invention discloses a stayed prestressed orthogonal space tube truss steel grid structure and a manufacturing method thereof. A grid (1) of the structure is formed by mutually orthogonally connecting x directional space tube trusses (2) arranged in the x direction and y directional space tube trusses (3) arranged in the y direction; x directional prestressed space tube trusses (4) are arranged at about 1 / 3 positions of two sides of the grid (1) in the x direction, and y directional prestressed space tube trusses (5) are arranged in the y direction; and prestressed steel cables (6) and steel cable steering support frames (7) are arranged on the x directional prestressed space tube trusses (4) and the y directional prestressed space tube trusses (5). The structure is in a novel steel grid roof structure form, and is applied to a super-large span (L is more than or equal to 120m and less than or equal to 180m), the plane dimension of which is close to square; under the condition of ensuring deformation and strength, the consumption of steel can be lowest, and the manufacturing cost of engineering is reduced; and the structure is a safe, reasonable, advanced and economic novel structure system.

Description

technical field [0001] The invention relates to a prestressed orthogonal space pipe truss steel grid roof structure, in particular to a super-large-span (120m≦L≦180m) underbracing prestressed orthogonal space pipe truss steel mesh structure and its manufacturing method. It belongs to the technical field of building structures. Background technique [0002] The quasi-beam space tube truss structure was introduced from abroad at the end of the last century. Its characteristics are: the structure is a shuttle space tube truss, that is, two steel pipes on the upper chord and one steel pipe on the lower chord are connected by four oblique web bars to form an inverted triangle section. Space tube truss, the upper chord is bent downwards, and the lower chord is bent upwards to form a shuttle; the grid of the structure is large, and the diameter of the steel pipe is large (compared to the flat grid); there are no steel balls at the intersection of the bars, and the secondary The pi...
