Description
Technical field
The present invention relates to building engineering field, node is transformed in specifically a kind of floor of steel structure.
Background technology
Now with the requirement of urban renewal development, the quantity of existing building strengthening reconstruction project increases year by year in China,
And the case where being frequently encountered reconstruction of floor slab, for the engineering containing steel construction, tradition of the new and old floor at steel beam bearing
Way is to reject a part of concrete so that newly-increased concrete floor can ride on girder steel.Though this way is possible in theory,
But cumbersome and quality of constructing in practical operation is not easy to ensure, often also needs to remove the peg on original girder steel so that new steel is held
Plate can be laid with, while also need to complement peg again, and difficulty of construction is larger.
To solve the above problems, needing to design a kind of floor of steel structure transformation node, solves difficulty of construction greatly and quality can
By the problem of property difference.The design requirement that node is transformed in floor of steel structure is that way is simple and direct, power transmission is clear, safe and reliable, is suitable for
The steel construction improvement project of various scales.
Invention content
The present invention is exactly to solve the above-mentioned problems, to provide a kind of floor of steel structure transformation node.
The present invention is implemented according to following technical scheme.
A kind of floor of steel structure transformation node, the floor of steel structure includes original floor, and original floor edge is equipped with steel
Beam is connected and fixed between original floor and girder steel by peg；Girder steel is H profile steel, and upper lower flange is each parallel to original building
Plate；Girder steel top flange edge is welded with the support plate for being parallel to original floor；On the support plate and girder steel lower flange and
Multigroup support plate ribbed stiffener is welded between web；Steel beam web plate other side position corresponding with support plate ribbed stiffener is welded with
Girder steel ribbed stiffener；Multiple newly-increased pegs are welded on form bracing plate, newly-increased floor is fastened on by peg and support plate
Together.
Further, the newly-increased floor is normal concrete floor, composite deck slabs or reinforcing bar purlin
Frame plate floor.
Further, the support plate is welded on the outside of girder steel top flange, and support plate is the steel plate not less than 8mm.
Further, the support plate ribbed stiffener and girder steel ribbed stiffener are each perpendicular to web and lower flange.
The present invention achieves following advantageous effect.
The present invention solves the problems, such as that general floor of steel structure rebuilding construction difficulty is ropy greatly, can avoid removing original
Part concrete on girder steel and peg can ensure that being reliably connected for original floor and girder steel be not disturbed, while avoid tearing open
Except work causes original girder steel different degrees of injury.This floor of steel structure transformation node way is simple and direct, can ensure to increase newly
The secure support of floor, while the setting of newly-increased peg can also ensure the horizontal power transmission of floor, this node construction convenience, power transmission
It is clear, safe and reliable, it is suitable for the structural steelwork of various scales.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention；
Fig. 2 is the left view of the present invention.
Wherein, 1. original floor；2. newly-increased floor；3. girder steel；301. top flange；302. lower flange；303. web；4. steel
Beam ribbed stiffener；5. support plate ribbed stiffener；6. support plate；7. peg.
Specific implementation mode
Referring to the drawings and embodiment carries out further technology explanation to the present invention.
As shown in Fig. 1~2, a kind of floor of steel structure transformation node, the floor of steel structure includes original floor 1, original
1 edge of floor is equipped with girder steel 3, is connected and fixed by peg 7 between original floor 1 and girder steel 3；Girder steel 3 is H profile steel, on
Lower flange is each parallel to original floor 1；3 top flange of the girder steel, 301 edge is welded with the support plate 6 for being parallel to original floor 1；
Multigroup support plate ribbed stiffener 5 is welded in the support plate 6 and girder steel 3 between lower flange and web 303；3 web 303 of girder steel is another
Side position corresponding with support plate ribbed stiffener 5 is welded with girder steel ribbed stiffener 4；It is welded on form bracing plate 6 multiple newly-increased
Peg 7, newly-increased floor 2 are connected and fixed by peg 7 and support plate 6.
The newly-increased floor 2 is normal concrete floor, composite deck slabs or steel bar girder slab-type apartment building plate.
The support plate 6 is from 3 top flange of girder steel, 301 outside welding, and support plate is the steel plate not less than 8mm.
The support plate ribbed stiffener 5 and girder steel ribbed stiffener 4 are each perpendicular to web 303 and lower flange 302.
The principle of the present invention and application method are：
The node is by girder steel 3, newly-increased floor 2, support plate 6, support plate ribbed stiffener 5, girder steel ribbed stiffener 4, peg 7 and original building
Plate 1 is constituted.It is mainly used for floor of steel structure improvement project.
When construction, first, by the side of the top flange of girder steel 3 301 welding form bracing plate 6, form bracing plate 6 with
Support plate ribbed stiffener 5 is welded on girder steel 3 between lower flange and web 303, corresponding to 5 position of support plate ribbed stiffener in the girder steel other side welds
Girder steel ribbed stiffener 4 is connect, then formwork pours floorslab concrete to weld stud 7 on form bracing plate 6, when floor is profiled sheet
When concrete combined floor or steel bar girder slab-type apartment building plate, first laying profiled sheet or steel bar girder plate, weld stud 7 is then again
Pour floorslab concrete.
The specification and spacing of support plate ribbed stiffener 5, girder steel ribbed stiffener 4, are determined on a case-by-case basis, its role is to enhance to hold
Power and stability are carried, such as newly-increased load of floor is larger, the support plate that thickness can be used larger, while increasing and being propped up in unit length
The quantity of fagging ribbed stiffener.
