Abstract
The utility model discloses a steel column base node with a layer, which is used for the top layer reconstruction of the existing building concrete structure, comprising a rectangular steel tube column, a steel tube column outer wrapping column base and micro-expansion self-compacting concrete, wherein the rectangular steel tube column is anchored with an anchor bolt after chiseling the original structure column and is consolidated with the original reinforced concrete column into a whole by recharging high-strength grouting material or fine stone concrete which is higher than the original concrete by a label; pouring reinforced concrete outer-wrapped column feet at the bottoms of the steel tube stand columns; the longitudinal steel bars of the outer-wrapped column feet are connected with the single side of the longitudinal steel bars of the original reinforced concrete column in a welding way; the outer wrapping column base is reliably connected with the upright column through studs uniformly welded on the outer wall of the periphery of the upright column; c40 micro-expansion self-compacting concrete is poured into the rectangular steel tube upright. The utility model discloses add layer steel column base node is applicable to existing building and directly increases the steel construction at original structure capital portion and adds the transformation engineering on layer, and the expanded existing building of being applied to adds the layer transformation engineering.
Description
Technical field
The utility model is related to the add-story reconstruction fields of existing building, and in particular to a kind of steel column foot node.
Background technology
With the progressively development of reconstruction of existing building engineering, steel adding storey transformation is small from heavy and light, geological process by it
The advantages that be just progressively extended to a kind of form of concrete building add-story reconstruction, domestic application is not also nothing very extensively at present
By be design calculate analysis or site operation in terms of it is all perfect not enough.After all, two kinds of different structural systems are integrated into one
The problems such as body, new and old structure is mutated in junction there are rigidity and quality, and original structure column capital region reinforcing bar is densely distributed,
There are plate muscle, beam muscle and column main reinforcement to receive head, the also anchoring to newly-increased steel column foot adds difficulty.
Utility model content
The purpose of this utility model is to provide a kind of convenient for constructing and can ensure work of the suspension column under complex stress
The suspension column structure of ability and adding storey structure globality.
To achieve the above object, the utility model adopts the following technical solution：
One kind plus layer steel column foot node including original reinforced column and add layer steel column, the reinforced column
Capital 50cm height inner concrete cut, the ground anchor bolt of the steel column is arranged at the reinforced column capital, and
It is one by the pea gravel concreten of recharge high-strength grout or a label higher than former concrete and original reinforced column consolidation
Body, the heel slab of the steel column are connected fixation by ground anchor bolt with the reinforced column；It is also poured in the steel column bottom
Armored concrete outsourcing suspension column, the longitudinal reinforcement of the outsourcing suspension column and the longitudinal reinforcement of the armored concrete column top are built
Single-sided welding；The steel column be rectangular steel pipe, inside be perfused with C40 concrete, be welded with T-shaped bolt in the outer wall of rectangular steel pipe
Nail.
The outsourcing suspension column height is 2100mm, the longitudinal reinforcement of the outsourcing suspension column and the armored concrete column top
Longitudinal reinforcement weld length be not less than 10d.
The beneficial effects of the utility model：
（1）It is densely distributed that the utility model has properly settled original structure column capital region reinforcing bar, have plate muscle, beam muscle and
Column main reinforcement receives head, and difficulty greatly this problem is implanted into after ground anchor bolt and reinforcing bar, construction quality is improved, reduces to original knot
The extent of the destruction of structure column.
（2）The utility model ensure that the entirety of original reinforced column and newly-increased steel column by setting outsourcing suspension column
Property.
Description of the drawings
By the detailed description made in conjunction with the following drawings, the above-mentioned and/or otherwise advantage of the utility model will
It becoming more apparent upon and is easier to understand, these attached drawings are simply schematical, are not intended to limit the utility model, wherein：
Fig. 1 is the utility model foot joint structure diagram.
Fig. 2 is that the utility model existing building original structure column picks chisel floor map.
Fig. 3 is that the utility model existing building original structure column picks chisel elevational schematic view.
In figure, 1- reinforced columns, 2- steel columns, 3- outsourcings suspension column, 4- raw steel Concrete Beam Reinforced, 11- armored concrete

Specific embodiment
One kind plus layer steel column foot node including original reinforced column 1 and add layer steel column 2, the armored concrete
The capital 50cm height inner concrete of column is cut, and the ground anchor bolt 21 of the steel column is arranged at the reinforced column column
Top, and the pea gravel concreten for passing through recharge high-strength grout or a label higher than former concrete is consolidated with original reinforced column
It is integrated, the heel slab 22 of the steel column is connected fixation by ground anchor bolt 21 with the reinforced column；In the steel column
Bottom has also poured armored concrete outsourcing suspension column 3, longitudinal reinforcement 31 and the reinforced column of the outsourcing suspension column
11 single-sided welding of longitudinal reinforcement；The steel column be rectangular steel pipe, inside be perfused with C40 concrete；In outsourcing suspension column height model
In enclosing, the outer wall of rectangular steel pipe is welded with T-shaped peg 23.
The outsourcing suspension column height is 2100mm, the longitudinal reinforcement of the outsourcing suspension column and the armored concrete column top
Longitudinal reinforcement weld length be not less than 10d.
The foregoing is merely the specific real modes of the utility model, are not intended to limit the utility model, every in this reality
With new spirit and any modification, equivalent substitution, improvement and etc. within principle, done, the utility model should be included in
Within protection domain.
