Description
Technical field：
It the utility model is related to floor of steel structure and bag girder connection interconnection technique field, more particularly to a kind of floor and girder steel
Attachment structure.
Background technology：
In steel house, the connected mode of generally use gib headed bolt between floor and girder steel, which scene needs
Drill, penetrate gib headed bolt and welded with girder steel, but scene drilling is it is difficult to ensure that the precision of hole site, often occurs partially
Difference, cause reaming again, the local stress increase of plate, potential safety hazard be present.
The fire prevention and sound insulation of other girder steel are also always an important factor for obstruction steel house develops, in the prior art steel
Beam is to reach fireproof effect by wrapping up fire proofing material, but is generally only wrapped up at the web of girder steel, therefore girder steel
Upper lower wing plate easily surrender in a fire, cause floor fall or wallboard fracture cause casualties.
The content of the invention：
The utility model provides the attachment structure of a kind of floor and girder steel, to solve floor in the prior art and girder steel
Connected mode flameproof effect is poor, and floor local stress is big, the problem of potential safety hazard be present.
The utility model provides a kind of attachment structure of floor and girder steel, including：Girder steel, floor, wallboard, L-type fire-proof plate
And angle steel；Girder steel includes upper flange, middle wing plate, lower wing plate, epiplastron and bottom web；Girder steel is section in " king " word shape
Strip steel, it is fixedly connected by epiplastron between upper flange and middle wing plate, is consolidated between middle wing plate and lower wing plate by bottom web
Fixed connection；Neck is surrounded between upper flange, epiplastron and middle wing plate, floor is caught in neck and is fixedly connected with girder steel；Girder steel
Lower wing plate bottom fix wallboard, girder steel both sides respectively parcel one piece of L-type fire-proof plate, one end abutment floor plate of L-type fire-proof plate
Face, another end abutment wallboard plate face, middle wing plate and lower wing plate are all fixedly connected by angle steel with L-type fire-proof plate.
Preferably, middle wing plate and lower wing plate it is relative side welding angle steel a wall, L-type is prevented fires by self threading pin
Plate is fixed on another wall of angle steel.
Preferably, floor uses autoclaved lightweight aerated concrete ALC plates.
Preferably, L-type fire-proof plate is the L-type cement foam board of primary concreting shaping.
Preferably, angle steel is L-type galvanized steel.
The utility model beneficial effect includes：By transforming steel beam structure, the connection that drilled at floor is avoided, more firmly
Reliably, L-type cement foam board has excellent fire prevention tolerant noise-insulating warm-keeping effect, overall to wrap up girder steel, and outside is decorated, L-type water
Mud foamed board can be used as decorative layer and serve as fire prevention again, play a part of so that girder steel and extraneous air completely cut off, when fire occurs,
Cement foam board forms isolation strip, avoids girder steel because fire is surrendered, and not only seam quantity is few for L-type integral installation, fire prevention
Excellent performance, and easy construction, reduce the waste of other fire proofing materials, reduce difficulty of construction and cost.L-type cement foam board
Gap between floor and wallboard is all filled using fire prevention clay, increases the fire resistance period of girder steel so that using the connection
The house of structure is more solid and reliable.
Brief description of the drawings：
Accompanying drawing 1 be a width better embodiment floor and girder steel attachment structure cross section structure schematic diagram.
Embodiment：
In consideration of it, the utility model provides a kind of attachment structure of floor and girder steel, below in conjunction with Figure of description pair
Preferred embodiment of the present utility model illustrates.
As shown in fig.1, the attachment structure of a kind of floor and girder steel, including：Girder steel, floor 2, wallboard 3, L-type fire-proof plate 4
And angle steel 5；Girder steel includes upper flange 101, middle wing plate 102, lower wing plate 103, epiplastron 104 and bottom web 105；Girder steel is to cut
Face is in the strip steel of " king " word shape, is fixedly connected between upper flange 101 and middle wing plate 102 by epiplastron 104, middle wing plate
It is fixedly connected between 102 and lower wing plate 103 by bottom web 105；Between upper flange 101, epiplastron 104 and middle wing plate 102
Neck is surrounded, floor 2 is caught in neck to be fixedly connected with girder steel；Wallboard 3, girder steel both sides are fixed in the bottom of lower wing plate 103 of girder steel
Respectively one piece of L-type fire-proof plate 4 of parcel, 4 one plate faces of end abutment floor 2 of L-type fire-proof plate, another plate face of end abutment wallboard 3,
Middle wing plate 102 and lower wing plate 103 are all fixedly connected by angle steel 5 with L-type fire-proof plate 4.
Wherein, a wall of the relative side welding angle steel 5 of middle wing plate 102 and lower wing plate 103, by self threading pin 6 by L
Type fire-proof plate 4 is fixed on another wall of angle steel 5.Floor 2 is using autoclaved lightweight aerated concrete (Autoclaved
Lightweight Concrete, ALC) plate.L-type fire-proof plate 4 is the L-type cement foam board of primary concreting shaping.Angle steel 5 is
L-type galvanized steel.
During construction, first L-type galvanized steel is uniformly distributed on the middle wing plate 102 and lower wing plate 103 for being welded on steel I-beam, so
Epiplastron 104 will be welded on steel I-beam afterwards, ALC plates are laid on and are welded with the girder steel of epiplastron 104, then by upper flange
101 form neck with the welding of epiplastron 104, and floor 2 is fixed on girder steel.L-type cement foam board self threading pin 6 is fixed again
On L-type galvanized steel, the outside of L-type cement foam board carries out decoration processing, and the lower wing plate 103 of girder steel is bonded in the upper end of wallboard 3
Portion；Gap caused by other connections, as floor 2 and girder steel neck at, junction of the L-type cement foam board with floor 2, L-type
The junction of cement foam board and wallboard 3, all filled using fire prevention clay 7, to greatest extent completely cut off girder steel and extraneous air.
