Description

A kind of floor of steel structure transformation node
Technical field
The utility model relates to building engineering field, node is transformed in specifically a kind of floor of steel structure.
Background technique
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 guarantee, 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 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, difficulty of construction is big and quality can for solution 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.
Utility model content
The utility model is exactly to solve the above-mentioned problems, to provide a kind of floor of steel structure transformation node.
The utility model 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 Multiple groups 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 is each perpendicular to web and lower flange, and with support plate and girder steel up and down The edge of a wing, web welding.
Further, the girder steel ribbed stiffener is each perpendicular to web and lower flange, and corresponding with support plate ribbed stiffener.
The utility model achieves following beneficial effect.
The utility model solves the problems, such as that general floor of steel structure rebuilding construction difficulty is ropy greatly, can be avoided dismounting Part concrete and peg on original girder steel can guarantee that being reliably connected for original floor and girder steel be not disturbed, keep away simultaneously Free removal work causes different degrees of injury to original girder steel.This floor of steel structure transformation node way is simple and direct, can guarantee The secure support of newly-increased floor, while the setting of newly-increased peg can also guarantee the horizontal power transmission of floor, this node construction facilitates, Power transmission is clear, safe and reliable, the structural steelwork suitable for various scales.
Detailed description of the invention

Fig. 2 is the left view of the utility model.
Wherein, 1. original floor;2. newly-increased floor;3. girder steel;301. top flange;302. lower flange;303. web;4. Girder steel ribbed stiffener;5. support plate ribbed stiffener;6. support plate;7. peg.
Specific embodiment
Referring to the drawings and embodiment carries out further technology explanation to the utility model.
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 between original floor 1 and girder steel 3 by peg 7;Girder steel 3 is H profile steel, on Lower flange is each parallel to original floor 1;3 top flange of girder steel, 301 edge is welded with the support plate for being parallel to original floor 1 6;Multiple groups 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 new Increase peg 7, newly-increased floor 2 is connected and fixed by peg 7 with 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 welded on the outside of 3 top flange 301 of girder steel, and support plate is the steel plate not less than 8mm.
The support plate ribbed stiffener 5 is each perpendicular to web 303 and lower flange 302, and with support plate 6 and girder steel 3 up and down The edge of a wing 301,302, the welding of web 303.
The girder steel ribbed stiffener 4 is each perpendicular to web 303 and lower flange 302, and corresponding with support plate ribbed stiffener 5.
The principles of the present invention and application method are as follows:
The node 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 floor 1 is constituted.It is mainly used for floor of steel structure improvement project.
When construction, firstly, by beside the top flange of girder steel 3 301 weld 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 303,5 position of support plate ribbed stiffener is corresponded in the girder steel other side and 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, depending on the circumstances, its role is to enhance to hold Power and stability are carried, such as newly-increased load of floor is larger, the biggish support plate of thickness can be used, while increasing and propping up in unit length The quantity of fagging ribbed stiffener.
