Abstract
The invention discloses a super-large span cylindrical combined bar system large grid structure, which comprises a main structure and a substructure which is arranged inside the main structure, and is characterized in that the main structure is a large grid structure which consists of lattice type members, and the grid dimension is between 10 and 30 meters; and the substructure is a common double-layer flat-plate grid rack and is embedded into a large grid in a mode of four-corner supporting to form a structural form of making a small grid sleeved into the large grid. The super-large span cylindrical combined bar system large grid structure can effectively overcome the defect of destabilization of compression bars, greatly improve the overall rigidity and the stability of the structure, avoid destabilization of the compression bars, save the steel consumption, and reduce the manufacturing cost of engineering. Moreover, both combined bars and the flat-plate grid rack substructure can be manufactured and processed in a factory into basic components with small number, conveyed and assembled on the spot into an overall structure, so that the field assembly workload is greatly reduced and the construction period is shortened. The super-large span cylindrical combined bar system large grid structure is suitable for a spatial reticulated shell roof structure with a super-large span of more than 200 meters.
Description
Technical field
The present invention relates to builing industry space structures field, specifically a kind of cylindrical surface compound rods giant grid structure of super-span.
Background technology
In buildings such as stadiums, conference and exhibition center, cinema, megastore, factory garage, all be that a kind of top is the large span space steel work, the bottom is the construction work of reinforced concrete structure.Using more a kind of form of structure in the large-span space structure at present is double-deck cylindrical latticed shell structure.Along with the development long-span space of society will develop to super-span.And this double-deck cylindrical latticed shell structure some unavoidable problem can occur along with the further increase of span, and when adopting 5m with interior normal length rod member, structure can easily cause whole unstability because of thick striding than too little; And rod member easily causes strut buckling when long because of internal force is excessive, and the steel using amount increase that causes therefrom etc.There is document analysis to show, it is also not obvious to the effect that improves the structural entity service behaviour to increase the number of plies, the more important thing is that it is infeasible adopting multilayer form to increase structural span with the restriction that breaks through internal force, rod member and node are sharply increased, and node too much makes the processing structure complicated more because of the rod member that connects.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of cylindrical surface compound rods giant grid structure of super-span is provided.To realize effectively breaking through the big internal force of rod member and pressure bar stabilization and structural entity stable restriction, can reduce steel using amount again, reduce construction costs.
Technical scheme of the present invention is: comprise agent structure and the minor structure two-stage that is arranged in the agent structure, it is characterized in that, described agent structure is a kind of macrolattice structure of being made up of latticed members, its size of mesh opening is 10～30m, described minor structure is common double-deck flat plate framed structure, minor structure is embedded in the macrolattice in the mode of four angle point supportings, forms the form of structure that a kind of macrolattice overlaps little grid.
The described macrolattice structure of being made up of latticed members is to be hinged and connected by large-sized welded hollow spherical joints by the lattice compound rod to form.
Two longitudinal edges of described macrolattice structure are provided with bearing.
Described lattice compound rod is the uniform section straight-bar, its two end is the pyramid bodily form, there is the long support that constitutes of being responsible for of 3-4 root the outside of interlude, internal stent is provided with several and long is responsible for vertical equilateral triangle or square tabula, be provided with between every adjacent two tabulas and tabula between the inclination angle be the diagonal web members of 45 ~ 55 degree.
Described equilateral triangle tabula is to constitute the equilateral triangle framework by three isometric round steel pipe, and the equilateral triangle framework is connected with long person in charge by direct junction node.
Described square tabula constitutes the square framework by four isometric round steel pipe, and the square framework is connected with long person in charge by direct junction node.
Be equipped with support bar in the described square framework, to prevent cross section generator dynamic deformation.
Described diagonal web member is a round steel pipe, the end through be machined into pass through face mutually after, directly be welded in long person in charge on the tube wall.
The form of structure that this macrolattice of the present invention overlaps little grid, can overcome the problem of strut buckling effectively, the integral rigidity that can increase substantially structure with stability, avoid strut buckling, to prop up tube end through be machined into pass through face mutually after, directly be welded in and be responsible on the tube wall, can avoid adopting any connector, save steel using amount, reduce construction costs; In addition, combined member bar and flat plate framed structure minor structure all can process at produce in factory and be the quantity basic element of character seldom, are transported to assembled on site then and form overall structure, will significantly reduce the on-site installation work amount, shorten the construction period.Applicable to the super-span space net shell roof structure more than the 200m.
