Steel core concrete column-arch without beam connecting node.
Background technique
The plate-column structure being made of arch without beam and steel core concrete column is due to building use space with floor free height
The advantages that big, is more and more widely used in building structure.But under geological process, slab column connection node is easy hair
Raw punching failure, thus caused floor damages more difficult reparation；If node punching failure is serious, or even can cause overall structure
Collapse.
Summary of the invention
Present invention aims at aiming at the shortcomings in the prior art, propose a kind of concrete filled steel tube that low damage is easily repaired
Column-arch without beam connecting node.
In order to solve the above technical problems, technical scheme is as follows:
A kind of steel core concrete column-arch without beam connecting node, the reinforced concrete floor being connected with steel core concrete column
Partial region replaced with steel-casting, the width in the region is 4-6 times of steel core concrete column width；
The steel-casting is made of center steel pipe and orthogonal steel plate grid；The orthogonal centrally disposed steel pipe of steel plate grid
Four lateral positions, and the steel plate section being connected in orthogonal steel plate grid with center steel pipe side sets respectively in top and bottom
It is equipped with arc groove, is formed and weakens section；
The center steel pipe and column steel pipe pass through flanged joint；Casting concrete forms the concrete filled steel tube in column steel pipe
Column is provided with circular hole on the outermost steel plate of the orthogonal steel plate grid, and the reinforcing bar of periphery floor passes through circular hole, and passes through bolt anchor
Gu on the steel plate.
The present invention also provides steel core concrete column as described above-arch without beam connecting node construction methods, including
Following steps:
1) it according to slab thickness, pillar sectional dimension, designs steel-casting and makes corresponding casting die；
2) the integral cast steel-casting on mold；
3) welded flange on the center steel pipe of steel-casting；
4) according to the position of floor bar, determine that orthogonal steel plate grid outermost steel plate corresponds to position and the completion of circular hole
Drilling；
5) floor slab formerecting, while steel-casting being positioned；
6) reinforcing bar of floor is passed through into orthogonal steel plate grid outermost steel plate and is anchored by bolt；
7) center steel pipe and column steel pipe are passed through into flanged joint；
8) build floor and pillar concrete are poured.After concrete strength reaches requirement, steel deck-plate is covered on steel-casting.
The present invention has the following advantages that compared with the existing technology and protrudes effect:
Low steel core concrete column-arch without beam connecting node the outstanding feature easily repaired of damaging proposed by the present invention is pair
The steel plate section section being connected in steel-casting with center steel pipe is weakened, to guarantee under geological process, structure yields are only sent out
Life is in the weakening section, other regions of floor can be from destroying, and structure be easy to repair.Present invention enhances steel core concrete columns-
The Punching Shear destructive characteristics of arch without beam connecting node, have broad application prospects in tier building.

Specific implementation method
Below in conjunction with attached drawing, specific implementation method of the invention is further described.
With reference to Fig. 1-Fig. 6, a kind of reinforced column-arch without beam connecting node that low damage is easily repaired is connected with column 2
The partial region of reinforced concrete floor 1 replaced with steel-casting, the width in the region is 4-6 times of 2 width of column, such as Fig. 1, is schemed
2.The steel-casting is made of center steel pipe 6 and orthogonal steel plate grid 7, such as Fig. 3, Fig. 4.The orthogonal steel plate grid 7 is arranged in
Four lateral positions of heart steel pipe 6, and the steel plate section being connected in orthogonal steel plate grid 7 with 6 side of center steel pipe, in upper end under
End is respectively arranged with arc groove, is formed and weakens section 9；It can guarantee that surrender only occurs in the weakening section 9, floor 1 in this way
Other regions can be from destroying, and structure is easy to repair, such as Fig. 5.
The center steel pipe 6 of steel-casting is connect with column steel pipe by flange 4；Casting concrete forms steel tube concrete in steel pipe 6
Earth pillar 2 guarantees that the shearing of floor 1 and moment of flexure can be reliably delivered to pillar 2.The outermost steel of the orthogonal steel plate grid 7
Circular hole is provided on plate 8, the reinforcing bar 5 of periphery floor passes through circular hole, and on the steel plate by the anchoring of bolt 10, such as Fig. 6.
Construction method of the invention the following steps are included:
