Description of the drawings
Fig. 1 be preferred embodiment a kind of build-in in basement Steel Frame Column build-in node structural representation
Figure.
Specific embodiment
The specific embodiment of the present invention is described in further detail below.
As shown in figure 1, according to the requirement of architectural design, Steel Frame Column 10 is arranged on basement（It is not shown）Outward, basement
Including top board Vierendeel girder 12, profile steel concrete column 14 is provided with the room of underground, profile steel concrete column 14 includes steel column 16 and arranges
Concrete layer 18 outside steel column 16；The cross section of Steel Frame Column 10 and steel column 16 is square or circle, Steel Frame Column 10
The diameter with diameter greater than steel column 16.
The present invention provides a kind of build-in in the build-in node of the Steel Frame Column 10 of basement, and it includes that is embedded in a top board framework
Connecting portion 20 in beam 12, Steel Frame Column 10 connects steel column 16 by connecting portion 20.Steel Frame Column 10, connecting portion 20 and steel column 16
Steel are, are fixedly connected by way of welding.
Connecting portion 20 is identical for the cross section shape of frustum structure, the bottom surface of connecting portion 20 1 and Steel Frame Column 10 and overlaps, even
Another bottom surface of socket part 20 is identical with the cross section shape of steel column 16 and overlaps.
Connecting portion 20 meets code requirement：The side grade of connecting portion 20 is less than or equal to 1：6；The thickness of concrete layer 18 is big
In equal to 300mm；The height of connecting portion 20 is identical with the thickness of top board Vierendeel girder 12.
Two bottom surfaces of connecting portion 20 are provided with diaphragm plate 22, and the plug hole of insertion is provided with diaphragm plate 22（Do not scheme
Show）.
Ungauged regions pea gravel concreten 24 is cast with Steel Frame Column 10.
Several pegs 26 are provided with the lateral wall of connecting portion 20 and steel column 16, for strengthening they and concrete layer
18 bond strength.
So that the cross section of Steel Frame Column 10 and steel column 16 is square as an example, the build-in of the present invention is in the steel framework of basement
The specific implementation method step of the build-in node of trestle 10 is as follows（Following labelling a, b, c are formula operation symbol, not accompanying drawing
Labelling）：
1, determine that the unification sectional dimension of profile steel concrete column 14 is (a × a) according to block mold result of calculation and building demand
Mm2, thus according to《Reinforced concrete composite structure technical regulation》（JGJ138-2001）The section length of side of steel column 16 is b=a- to the maximum
300 mm, sectional dimension is (b × b) m2
2, extract and consider that concrete of basement beam balances the capital internal force in the block mold after a part of internal force, according in this
Power is optimized design to the section of profile steel concrete column 14, determines reinforcing bar panel thickness.
3, according to the size of top Steel Frame Column 10（c×c）Determine that node does with the difference of the size of bottom steel column 16 (b × b)
Method, because steel structure variable-section has gradient i≤1:6 requirement, therefore as (c-b)=100mm, connecting portion 20 needs 600mm
Height, i.e., now need high 600 mm of top board Vierendeel girder 12, and by above-mentioned rule, the rest may be inferred.
4, determine adjust entire mathematical model after the section of steel column 16 and top board Vierendeel girder 12 as stated above, to structure entirety
Index is investigated, it is ensured that result safety.
A kind of above example only present invention embodiment therein, its description is more concrete and detailed, but can not
Therefore it is interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art,
Without departing from the inventive concept of the premise, some deformations and improvement can also be made, these belong to the protection model of the present invention
Enclose.Therefore, the protection domain of patent of the present invention should be defined by claims.
