Abstract
The utility model relates to an extensible double-layer latticed shell structure which comprises an upper double-layer latticed shell structure, lattice type columns and lower independent bases. The lattice type columns are connected with both ends of the upper double-layer latticed shell structure through bolts. The lower independent bases are connected with the bottoms of the lattice type columns. Detachable rod units are arranged in the middle of the upper double-layer latticed shell structure. A detachable column base joint construction is arranged between the lower independent bases and the lattice type columns. By means of the extensible double-layer latticed shell structure, span extension can be achieved by dismantling of some rod parts and by one-side translation based on changes of building functions.

Technical field
The utility model relates to a kind of double-layer latticed shell structure of expanding, and belongs to building structure field.
Background technology
The curved space structural system that latticed shell structure system is formed by connecting by node by beam element, the advantages such as this system is good due to its reasonable stress, Stability Analysis of Structures row, easy construction now have been widely used in all types of industries and civilian construction.Along with the development of industrialization of construction industry technical level, space truss structure often adopts the job practices of prefabrication, job site assembly unit, and when member after assembly unit is completed at the scene, structure becomes forever, fixing building.
The development of modern technologies is maked rapid progress, when latticed shell structure application and industrial construction or some public building, when the technological level of industrial construction or the function of architecture change, existing building and structure may occur and can not satisfy that technical level requires or the needs of public activity.For present cylindrical reticulated shell structure, when building function changes, can't realize expansion to existing structure, to build separately after must removing, this will cause the great wasting of resources.
The utility model content
Can't realize extendible present situation for overcoming the existing space network, the utility model has proposed a kind of Two-layer Cylinder Lattice Shell and installation and removal extended method thereof expanded based on the loading characteristic of latticed shell structure.This structure can realize under the condition of not removing existing structure, special node was set at the bottom of latticed shell structure top and post by the construction initial stage, when building function changes, can be by after removing the part rod member, utilize pulling equipment with the structure translation, and by setting up expanding element, the span of change structure and local height.
The technical solution of the utility model is as follows:
A kind of double-layer latticed shell structure of expanding, comprise upper part of double latticed shell structure, lattice post and single footing, bottom, described lattice post is connected with upper part of double latticed shell structure bolts at two ends, be used for to support the upper part of double latticed shell structure, and single footing, described bottom is connected with the lattice column bottom; Be provided with dismountable bar unit in the middle of described upper part of double latticed shell structure, be provided with dismountable foot joint structure between single footing, bottom and lattice post.
Described dismountable bar unit comprises web member, chord member, cast steel node and outer sleeve, outer sleeve one end is connected with cast steel node, the outer sleeve other end and chord member, web member are fixed by screwed connection, and the web member of dismountable bar unit, chord member are connected with other rod member, the node at upper part of double latticed shell structure two ends respectively.
Described dismountable foot joint structure comprises bolt, bearing steel plate, cushion block, plain concrete filler, built-in fitting, described bearing steel plate is connected with the lattice column bottom, built-in fitting is connected with the single footing, bottom, be provided with cross plain concrete filler between bearing steel plate and built-in fitting, four, cross plain concrete filler interior angle zone is provided with cushion block, and screw bolt passes bearing steel plate, cushion block, built-in fitting and single footing, bottom are fixed.
Beneficial effect
The utlity model has following beneficial effect:
1. effectively utilized the loading characteristic of double-layer latticed shell structure, double-layer latticed shell structure has the feature of stressed large, the stressed less of edge chord member of span centre chord member, and this provides technical foundation for expansion.After structure extension, the original structure span centre moves to the edge, can satisfy the force request of the rear structure of expansion.For the extension member of span centre extended area, but otherwise designed adopts the relatively large member in cross section, can effectively guarantee to expand the safety and stablization of rear structure.
2. the main truss of latticed shell structure of the present utility model is comprised of upper part of double latticed shell structure, lattice post, single footing, bottom, and net shell and lattice post are bolted, and the lattice post is connected with the single footing.Compare with traditional Double-level Reticulated Shell, can expand Double-level Reticulated Shell by adopted the foot joint structure of easy-to-dismount bar unit and slip at net shell top, realized the extensibility of structure, fill corresponding chord member and web member at extended area after expansion.
3. can expand the load-carrying members that double-layer latticed shell structure can be applicable to middle-size and small-size hangar, stadiums, warehouse, Exhibition Architecture, with respect to the longspan structure that can not expand, the utility model has stronger compliance, economizes on resources and the time, raise the efficiency, very important realistic meaning is arranged.
