specific Embodiment approach 1

[0020] Specific implementation mode one: as Figure 1-8 As shown, the concrete-filled steel tube arched space grid structure of this embodiment includes multiple arched trusses 7 and multiple connecting rods 4, and each arched truss 7 includes an upper chord 1, two lower chords 2 and several webs 3. The upper chord 1 and the two lower chords 2 form an arched truss with a triangular cross-section through several webs 3, and webs 3 are arranged between the upper chord 1 and the lower chord 2, and multiple arched trusses 7 and multiple The root connecting rods 4 are connected to form a spatial grid structure, and the arched truss 7 also includes supports 5, and the two ends of the arched truss 7 are respectively provided with supports 5, and the supports 5 are connected to the foundation.

[0021] The upper chord 1, the lower chord 2 or the web 3 of the arched space grid structure can be poured with concrete in whole or in part.

[0022] The arched spatial grid structure include...

specific Embodiment approach 2

[0024] Specific implementation mode two: as Figure 1-8 As shown, the upper and lower chords of the arched spatial grid structure of steel pipe concrete in this embodiment are continuous arc or broken line, and the upper chord 1 and the lower chord 2 are continuous arc steel pipes or discontinuous straight steel pipes to form folded lines. Linear steel pipe, web bar 3 and connecting rod 4 are straight steel pipes. With such a design, the upper chord 1 and the lower chord 2 can withstand axial pressure. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0025] Specific implementation mode three: as Figure 6 As shown, the space between the adjacent arched trusses 7 and the plurality of connecting rods 4 of the arched spatial grid structure in this embodiment is in the form of an evacuated grid. Such a design can further reduce the amount of steel used. Other compositions and connections are the same as those in Embodiment 1 or 2.

Abstract

The invention provides a CFST (concrete filled steel tube) arched space grid structure, relates to an arched space grid structure and solves the problems of high steel consumption and high cost due to the fact that a conventional large-span steel structure generally adopts a grid structure or a truss structure. Each arched truss (7) comprises an upper chord (1), two lower chords (2) and a plurality of web members (3), wherein the upper chord (1) and the two lower chords (2) constitute the arched truss with a triangular cross section through the plurality of web members (3), and the web members (3) are distributed between the upper chord (1) and the lower chords (2); the multiple arched trusses (7) and multiple connecting rods (4) are connected to form the space grid structure; each arched truss (7) further comprises support seats (5), and the support seats (5) are arranged at two ends of the arched truss (7) respectively and connected with a foundation. The CFST arched space grid structure is applied to a large-span space structure.

Description

technical field [0001] The invention relates to a steel tube concrete arch space grid structure, which belongs to the field of civil engineering building structures. Background technique [0002] With the development of the economy and the improvement of people's living standards, the requirements for the environment are getting higher and higher, and the demand for large-span space structures is increasing. [0003] Existing long-span steel structures generally adopt structures such as grids and trusses, and their main disadvantages are large steel consumption and high cost; the use of existing long-span steel structures cannot reduce the amount of steel used, and the amount of steel used and its strength are Proportional to reduce the amount of steel used strength can not meet the standard. [0004] To sum up, the existing long-span steel structures generally adopt grid and truss structures, which have the problems of large steel consumption and high cost. Contents of t...
