Specific embodiment
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and cooperate attached drawing
Detailed description are as follows:
If attached drawing 1 is to shown in Fig. 5, a kind of the double steel plate compound shear wall and composite floor connecting node of H profile steel connection are wrapped
Include double steel plate shear wall 1, composite floor 2 and inequilateral H profile steel beam 3.
The composite floor 2 includes reinforcing bar and steel construction main body 5 in floor, reinforcing bar and steel construction main body 5 in the floor
Including upper reinforcement, lower rebar and steel bar girder, or, including upper reinforcement, lower rebar, the thin steel of steel bar girder and bottom
Plate or, including the profiled sheet of upper reinforcement, lower rebar and bottom different-thickness, and can configure structure according to different requirements
Make reinforcing bar.In the present embodiment, the composite floor 2 is detachable reinforcing steel truss floor support plate.
The double steel plate compound shear wall 1 interrupted with the junction of the composite floor 2 be divided into upper layer shear wall and under
Story shear wall, the upper layer shear wall and lower layer's shear wall include two blocks of opposite steel plates 6, two blocks of steel plates 6 it
Between form concrete pouring cavity.
The inequilateral H profile steel beam 3 includes the lower flange of web, the top flange and lengthening that shorten.The upper layer shear wall
The inequilateral H profile steel beam 3 is fixedly connected on by welding manner respectively with two blocks of steel plates 6 of lower layer's shear wall
On the outer surface of top flange and lower flange.The upper reinforcement of the composite floor 2 is continuous in the inequilateral H profile steel Liang3Chu,
And pass through the web of the inequilateral H profile steel beam 3.The lower rebar or bottom sheet metal or profiled sheet of the composite floor 2
It is interrupted in the inequilateral H profile steel Liang3Chu, the thin steel of the lower rebar or bottom positioned at 3 two sides of inequilateral H profile steel beam
Plate or profiled sheet lead to respectively on the inner surface for the lower flange that welding manner is fixedly connected on the inequilateral H profile steel beam 3.Institute
The lower flange two sides for stating inequilateral H profile steel beam 3 are arranged at intervals with for preventing the composite floor 2 from generating horizontal direction sliding
Shearing bolt 4.
Node steel construction main body of the invention can be prefabricated in the factory, and on-site consolidation is completed, as shown in Figure 2.First by two
Steel plate 6 described in block is connect with inequilateral H profile steel beam 3 by fillet weld, after in 3 positioned internal shearing bolt 4 of inequilateral H profile steel beam
And the lower rebar (or bottom sheet metal or profiled sheet) of composite floor 2, and by shearing bolt 4 and lower rebar (or bottom
Sheet metal or profiled sheet) it is welded with 3 lower flange inner surface of inequilateral H profile steel beam；The upper reinforcement of composite floor 2 has needed simultaneously
Web is passed through entirely.Wherein, double steel plate compound shear wall 1 selects thinner thickness person (< 200mm), more meets current assembled steel knot
The development trend of structure house.The lower rebar of reinforcing bar and steel construction main body 5 in floor, bottom sheet metal, profiled sheet edge
Spacing between the web of inequilateral H profile steel beam 3 cannot be less than 20mm, and cannot be less than the lower flange of inequilateral H profile steel beam 3
50mm in overhanging marginal, best performance are that edge and web spacing cannot be less than 20mm, and must not exceed double steel apart from section
6 outer edge of steel plate of board group combination shearing wall 1.The top flange length of inequilateral H profile steel beam 3 is according to the double steel plate compound shear wall
1 thickness determines, and suitable weld size is reserved on both sides, generally takes top flange length=double steel plate compound shear wall 1
Thickness+20mm.Support composite floor 2 is played the role of in lower flange, and the length is top flange length+2l1, 120mm > l1>=50mm,
Wherein, l1To choose length outside, as exceed the length of double steel plate compound shear wall 1；Top flange length is shorter to be examined for site welding
Consider.The height of web is determined by composite floor 2 height itself, is 5 height of reinforcing bar and steel construction main body in the floor of composite floor 2
+l2, 20mm >=l2>=10mm, wherein l2For newly-increased height.The edge of a wing of inequilateral H profile steel beam 3 and web thickness meet width-thickness ratio
And the requirement of ratio of height to thickness.Spaced apart transverse stiffener can be added in web two sides in inequilateral H profile steel beam 3, need to meet
Extension, thickness and rigidity requirement.
Double steel plate compound shear wall in practical projects, is first installed and is poured by node of the invention, guarantees that structure is whole
Stability.Unify installation laying afterwards and pours composite floor.
The present invention handles H profile steel beam using unequal-sided mode, and lower flange, which lengthens, is used for support floor, and top flange shortens
Internal structure is facilitated to weld.Simultaneously by adjust web height and setting transverse stiffener, be suitable for different height, span,
The composite floor 2 of width.Floor upper reinforcement passes through the web of inequilateral H profile steel beam 3, and lower rebar or sheet metal are welded on not
The lower flange inner surface of equilateral H profile steel beam 3, guarantees nodes domains entirety stress, and mode of transfer force is clear.In engineering, in floor
Reinforcing bar and steel construction main body 5, inequilateral H profile steel beam 3, double steel plate 6 can be prefabricated, assembled in situ, wherein can in composite floor 2
Freely bind distribution bar at the construction field (site), after according to sequence of construction unify casting concrete；Guarantee connection stiffness, reduces construction
Difficulty meets the trend of assembling type steel structure building.
Although the preferred embodiment of the present invention is described above in conjunction with attached drawing, the invention is not limited to upper
The specific embodiment stated, the above mentioned embodiment is only schematical, be not it is restrictive, this field it is common
