Description
Technical field
The invention belongs to the technical field of Structural Engineering, be related to a kind of New Thin-walled steel core concrete column with ribbing construction and
Production method.
Background technology
The vertical supporting member that steel core concrete column refers to the fill concrete in steel pipe and formed, using steel pipe to core
Compression concrete in area's applies sidewise restraint, is at the stress state of three dimension stress, delay its longitudinal microcrack generation and
Development improves its compression strength and compression deformation ability, therefore has the characteristics of large carrying capacity, plasticity and good anti-seismic performance.
But conventional steel concrete column section is mostly circle, and the column of circular cross-section and the beam connection of rectangular section are more complicated, and in beam column
Steel pipe needs to penetrate through at connecting node, and which increases the difficulty of construction at bean column node.In addition the steel pipe continuously penetrated through also makes
Obtaining vibrating for steel duct concrete becomes difficult, so as to influence construction quality.Steel core concrete column also exists in actual use
The problems such as steel using amount is larger, and steel pipe needs to carry out anti-corrosion fire prevention maintenance.
For problem present in above-mentioned existing engineering, the present invention proposes a kind of New Thin-walled steel core concrete column with ribbing
Construction and production method, including the lattice steel pipe skeleton that the batten plate by cold-pressing quality steel and with hanging hole is welded to form, hung on batten plate
The precast slab and cylinder inner concrete put.The Novel steel pipe concrete pole remains the excellent of conventional steel concrete column
Point, by lattice rectangular steel pipe skeleton to core concrete generate cuff effect of contraction, make core concrete be in three-dimensional by
The characteristics of pressure condition makes it have intensity height, and plasticity is good；In addition the steel duct ribbed stiffener formed by bending steel plate can be carried effectively
The vertical rigidity and bearing capacity of Gao Zhu, and increase the adhesive property of steel pipe and inner concrete.Simultaneously because novel steel tube coagulation
The cross section of earth pillar is rectangle, and there are certain spacing between batten plate on facade, this just effectively solves the company of bean column node
Problem is connect, but also the enhanced convenience of vibrating of inner concrete.Precast slab (PC plate) with buckle, which is placed in, to be sewed
It on plate, is formed and closed in rectangular steel pipe skeleton surrounding, such PC plate can have both been served as when rectangular steel pipe inner concrete pours
Exterior sheathing, moreover it is possible to fire prevention and the Anticorrosion of steel construction are effectively solved as protective layer.New Thin-walled proposed by the present invention is with ribbing
Steel core concrete column is constructed and made simply, is suitable for being factory produced, is met the demand of building industrialization.
The content of the invention
In order to solve the problems in the prior art, the purpose of the present invention is to provide a kind of New Thin-walled steel core concrete column with ribbing
Construction and production method.
The present invention is achieved through the following technical solutions：
Equal leg angle with ribbing is bent to form with 4 pieces of cold-pressing quality steels processes three times and steel batten plate welds and to form cross section zonula occludens
The rectangular steel pipe skeleton of rib；Precast slab (PC plate) with buckle is placed on batten plate, in rectangular steel pipe skeleton four
Week forms closing；Casting concrete in spatial domain is segmented into steel pipe skeleton, forms rectangular steel-tube concrete column with ribbing；Steel pipe skeleton
Apply sidewise restraint to core space concrete, while ribbed stiffener can increase the vertical rigidity and bearing capacity of steel pipe, steel pipe and inside
Concrete forms vertical bearing system together.
The rectangular steel pipe skeleton with ribbing is bent to form equal leg angle with ribbing three times by being passed through with 4 blocks of clod wash steel plates
It is welded with steel batten plate.Steel pipe skeleton forms closed system on cross section, and the equal leg angle length of side is 90mm, thickness 6mm,
Batten plate is formed using the steel plate cutting of 6mm thickness and is opened Pear-Shaped hole.Along 4 pieces of angle steel longitudinal directions one of batten plate, shape are welded every 1 meter
Rectangular lattice steel pipe skeleton.
The prefabricated PC plate length is 1m, and thickness 30mm, it is empty for being hung on batten plate Pear-Shaped that inner surface leaves bayonet
It is interior, together with rectangular steel pipe skeleton there is resistance to pressure measurement template, while play and to form concrete cover on the outside of steel pipe
Effect.
New Thin-walled steel core concrete column with ribbing, when steel pipe skeleton with ribbing is hung with peripheral PC plate and fixes completion
Afterwards, the spatial domain in rectangular steel pipe is filled up with pump concrete and vibration compacting, maintenance waits intensity to reach requirement, nothing
Need striking job.
It is an advantage of the invention that：Lattice rectangular steel pipe to core concrete apply sidewise restraint, be at three-dimensional by
The stress state of pressure, the setting of internal ribbed stiffener can improve the rigidity and bearing capacity of column, while increase steel pipe and inner concrete
Cohesive force so that pillar have large carrying capacity, plasticity and good anti-seismic performance the characteristics of.By bending steel plate and welding shape
Into steel core concrete column with ribbing, the processing cost and process of the welding of pipe stiffener rib are eliminated.This external enwergy pillar cross-section is
Rectangle, there are certain spacing between batten plate on facade so that the connection of bean column node is relatively simple.Lattice rectangle steel cannon born
Frame plug-in prefabricated PC plate with steel pipe together as the template of resistance to pressure measurement, thus during placing concrete, can save formwork, form removal
Work and material, and it is suitable for advanced pumping grouted-aggregate concrete technique.Lattice rectangular steel pipe cost of manufacture with ribbing is compared with framework of steel reinforcement
It is lower and convenient for placing concrete, more applicable factory industryization processing.Lattice rectangular steel pipe skeleton with ribbing is again in itself stiffness
Load-bearing skeleton, in the construction stage, it can play stiff skeleton, and welding job amount is few, lifting more than normal section steel skeleton
Lighter weight so as to simplify installation technology, improves work efficiency.
