Abstract
The invention relates to a rigid connection joint of a steel tube concrete pile and a steel beam in a steel tube concrete structure system. The steel tube concrete pile intersects with the steel beam; the steel beam extends inwards the steel tube concrete pile; end parts of upper and and lower flange plate extension sections of the steel beam inside the steel tube concrete pile are respectively connected with end plates; upper and lower reinforcing rings are coaxially arranged inside the steel tube concrete pile and are respectively connected with an upper flange plate extension section and a lower flange plate extension section at a plane; and peripheries of an upper reinforcing ring and a lower reinforcing ring are connected with an inner wall of the steel tube concrete pile at the plane. With the adoption of the rigid connection joint, the joint is stressed more reasonably, safely and reliably; construction becomes more convenient; quality is ensured more easily; and an economic performance is improved significantly.
Description
Technical field
The present invention relates to the civil structure engineering field, espespecially in the encased structures system, when arranging steel core concrete column, be rigidly connected a kind of joint form of employing of steel core concrete column and girder steel.
Background technology
Encased structures has that bearing capacity is high, anti-seismic performance good, the advantages such as easy construction, can adapt to the modern project structure to the needs of striding greatly, towering, heavy duty develops and bear mal-condition, the industrial requirement that meets the Modern Construction technology, thereby in highrise building, be widely applied over past ten years, develop very rapid.
In encased structures, the diameter of steel core concrete column hour, being rigidly connected between girder steel and the steel core concrete column can adopt outer annular-stiffer to be connected, outer annular-stiffer is the full ring around the sealing of steel core concrete column; When the diameter of steel core concrete column was larger, being rigidly connected between girder steel and the steel core concrete column can adopt interior reinforcing ring to be connected.
According to existing documents and materials, in the larger diameter steel core concrete column, adopting during the reinforcing ring connected mode, owing to the plate of reinforcing ring is wide must be more than or equal to 0.25 times of concrete filled steel tube column diameter, the steel using amount of node region is larger, economic performance is not good; Simultaneously, when interior reinforcing ring width is larger, the pouring quality of steel pipe column inner concrete will be affected.
Summary of the invention
In order to overcome the weak point of above-mentioned joint form, main purpose of the present invention aims to provide the form of architecture joints of a kind of reasonable stress, construction facility, safety economy.
For solving the problems of the technologies described above, the basic scheme that the present invention adopts is as follows:
The rigid connection node of a kind of steel core concrete column and girder steel, comprise that steel core concrete column and girder steel intersect, described girder steel extends in described steel core concrete column, the end of the up and down frange plate extension of described girder steel in described steel core concrete column is connected with end plate respectively, reinforcing ring is coaxial up and down is positioned at described steel core concrete column, be connected with bottom wing listrium extension with the top flange plate extension respectively and be connected, the periphery of described upper reinforcing ring and lower reinforcing ring planar is connected with the inwall of described steel core concrete column.
Technique scheme is optimized for existing steel pipe column-girder connection, and described interior reinforcing ring has adopted segmented mode, adopts than heavy-gauge sheeting at the stressed position that needs, and adopts structure thickness sheet material at stressed less important position; The reinforcing ring width can be broken through in the prior art the restriction of ring flat-plate width, and width can be less than 0.25 times of concrete filled steel tube column diameter.The width meeting that reinforcing ring is less and is conducive to the control of construction quality so that concrete pouring construction can more successfully carry out.
Extension, the edge of a wing in the technique scheme is definite according to the requirement of the weak member of strong node, and its width and thickness require according to structure and design conditions are determined.
End plate size in the technique scheme can be definite according to the loading characteristic adjustment of post-girder connection, and end plate size (width, height and thickness) needs to satisfy the requirement to girder steel end rigid constraint.
Based on above-mentioned basic scheme, can look the connection between steel core concrete column and the girder steel, between upper reinforcing ring and lower reinforcing ring, vertical stiffening rib is set, a side of described vertical stiffening rib is connected with the inwall of described steel core concrete column.Certainly, also can not arrange vertical stiffening rib.
The present invention is particularly useful in Large-diameter Steel pipe concrete column-girder connection, has adopted reinforcing ring and the end plate joint form that is connected, and has both saved and has used material, can satisfy again the stressed demand of node.End plate can satisfy the Condition of Strong Constraint to described girder steel when less specification condition, under filling concrete dense reality condition.
The present invention is directed to larger diameter steel core concrete column-girder connection and carried out structural analysis and structural test, this make so that joints is more reasonable, safe, reliable, construct more convenient and easily ensure the quality of products, economic performance has obvious lifting.
Description of drawings
Fig. 1 is construction plan view of the present invention.
Fig. 2 is the A-A sectional drawing among Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the making of the embodiment of the invention and assembly unit step are as follows:
1. adopt the sheet material roll bending and splice welding, form the steel core concrete column 1 that meets design requirement.
2. in steel core concrete column 1, the upper reinforcing ring 3a that welding has positioned and lower reinforcing ring 3b, top flange plate extension 4a and bottom wing listrium extension 4b reach the up and down stiffening rib 6 between the reinforcing ring; Simultaneously, in the outer splice sections corresponding according to designing requirement welding and girder steel 2 of steel core concrete column 1.
3. in node of the present invention, welded end plate 5, as shown in the figure, end plate 5 lays respectively at the end of top flange plate extension 4a and bottom wing listrium extension 4b.
4. after finishing the detection of construction quality and acceptance(check) relevant with steel work, carry out the concreting in the steel core concrete column 1.If when in the Large-diameter Steel pipe concrete column, being furnished with in addition the reinforcing bar stem stem, should carrying out first the lifting of reinforcing bar stem stem, and after the acceptance(check) of reinforcing bar stem stem, carry out again concrete construction.
The above scheme that the embodiment of the invention is provided is introduced in detail, and for one of ordinary skill in the art, the thought according to the embodiment of the invention all will change in specific embodiments and applications.In sum, this description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
