Between each oblique fulcrum bar supporting base end portion and column, be provided with two ends respectively with the fixing lacing wire of winding up of oblique fulcrum bar supporting base end portion, column.Each oblique fulcrum bar and the lacing wire of winding up constitute an A-frame, and the lacing wire of winding up increases the support strength of oblique fulcrum bar on the one hand, makes floor plate become polygon support by multi-point support on the other hand, further increases and improved the support effect to each floor panel.
Column, oblique fulcrum bar can form or cast-in-place moulding with the steel concrete system of giving; Also can adopt steel work, as steel pipe; Also can adopt encased structures, promptly at hollow pouring concrete within steel pipe.When column, oblique fulcrum bar are concrete precast element or cast-in-place moulding, between oblique fulcrum bar and column, being connected and fixed between lacing wire and column and oblique fulcrum bar end of winding up, can adopt that the mode of built-in connection realizes mutual being connected and fixed in concrete; When being steel work or encased structures, adopt on column welding fixing.The sectional dimension and the material of column are selected for use according to structural calculation; Along with the variation of post distance, the sectional dimension of oblique fulcrum bar and all change with the design parameterss such as angle of column.But purpose of the present invention only is to provide the main structure body formation and the structure partly of this building umbrella-shaped structure, particularly this building structure.The quantity of oblique fulcrum bar can be selected four, six, eight, ten as required for use.
Column is made assembling,, upwards assembles gradually according to construction speed as an assembly unit with each floor height.When column adopted concrete precast element, the end of each assembly unit was provided with grafting key, the groove of realizing assembling mutually, makes between each column assembly unit and assembles better, connects.Column adopts steel work, encased structures, can directly weld fixing between each assembly unit of column.
The oblique fulcrum bar that the present invention is positioned at the stair opening part on building edge, the floor plate omits according to the floor plate shape, thereby forms the part variation of oblique fulcrum bar structure.
Be cast with or be shaped in advance the dark beam that floor plate is divided into grid on the floor plate, oblique fulcrum bar is supported under the dark beam on the floor plate.Dark beam action is the rigidity that further increases floor plate; Can reduce simultaneously the dark beam of the floor plate thickness of part in addition, thereby reduce the material usage of floor plate.
Umbrella building structure of the present invention has been saved material usage because the power transmission route is short and saved a large amount of primary and secondary beams, and under equal conditions its rolled steel dosage is saved approximately 50% than reinforced concrete frame structure, and concrete amount saves about 30%.As a kind of technique effect, this umbrella pillar construction has been started a kind of new job practices---three-dimensional job practices, promptly upwards building column and oblique fulcrum bar concrete the time, the floor plate of constructing simultaneously, above each layer of also can constructing simultaneously, form three-dimensional construction, cross-operation, help accelerating construction progress.The shared height space of oblique fulcrum bar can be hung various pipelines, just need not fit up and can form graceful moulding.This umbrella building structure can obtain the more form of structure of huge pillar net.
