Description
Technical field
The present invention relates to a kind of construction techniques, is to be related to a kind of assembling type steel structure girder steel overlapping building specifically
Plate connection method.
Background technology
In assembling type steel structure engineering, superimposed sheet is typically mounted at the top flange of girder steel.Because girder steel is all in floor
Below, in use, girder steel needs brush Fireproof antirust coating；In order that seen with process Sino-U.S., it is necessary in girder steel lower flange
Hang one layer of top；The building of same function, in order to meet the requirement of clear height in specification, the floor height of steel building is typically all than other
Structure type is high；Need to configure truss bars in laminated floor slab；So as to cause steel building cost higher.
The content of the invention
For above-mentioned deficiency of the prior art, the present invention provides a kind of reduction construction cost, improves efficiency of construction, ensures
The assembling type steel structure girder steel laminated floor slab connection method of construction quality.
The technical solution used in the present invention is：
A kind of assembling type steel structure girder steel laminated floor slab connection method,
Laminated floor slab time girder steel lower flange is prefabricated in laminated floor slab, and lower flange meets that fire prevention will away from the following edge thickness of superimposed sheet
Ask；
The connecting node position concrete of time girder steel and the main girder steel of structure reserves the connection gap of installation in superimposed sheet；
Superimposed sheet is being tapped to the pre- retained tongue and groove in the main girder steel position of structure；
The main girder steel top flange width of structure is less than lower flange width；
Superimposed sheet is arranged on the lower flange of the main girder steel of structure；Crouched under superimposed sheet to the main girder steel lower flange of structure；Superimposed sheet edge
Reserve gap in the main girder steel direction of structure；
After component installs, in structure main girder steel lower flange direction formwork, casting concrete, concrete grout flows into along gap
Girder steel lower flange；
Superimposed sheet last layer has been poured, and after ground surface finishing layer has been constructed, girder steel has all been rolled in floor.
It is 1000mm, spacing 500mm, gap width 50mm that the superimposed sheet reserves gap length along main body girder steel direction.
The superimposed sheet is tapped to the pre- retained tongue and groove in the main girder steel position of structure, and superimposed sheet is tapped to lower flange of girder edge 20mm.
The secondary girder steel is prefabricated in laminated floor slab.
The connecting node position concrete of time girder steel and the main girder steel of structure reserves the connection gap of installation in the superimposed sheet.
The beneficial effect of the present invention compared with the prior art：
Assembling type steel structure girder steel laminated floor slab connection method of the present invention, avoid girder steel exposure in atmosphere, avoid girder steel and exist
Brush antirust fireproof paint during use, furred ceiling expense is reduced, saves truss bars, reduce the height of floor, reduce construction cost,
Efficiency of construction is improved, ensures construction quality.

Embodiment
Referring to the drawings and embodiment the present invention will be described in detail：
Knowable to accompanying drawing 1-4, a kind of assembling type steel structure girder steel laminated floor slab connection method.
The secondary lower flange of girder steel 2 is prefabricated in laminated floor slab 1, and lower flange meets fire protection requirement away from the following edge thickness of superimposed sheet；
It can be fallen vertically during in order to facilitate installation superimposed sheet 1, the connecting node position of the secondary girder steel 2 in superimposed sheet 1 and main girder steel 5
Concrete reserves connection gap 3；
The pre- retained tongue and groove 4 in the main position of girder steel 5 is tapped at the edge of superimposed sheet 1；
The main top flange width of girder steel 5 is less than lower flange width；
Superimposed sheet 1 is arranged on the lower flange of main girder steel 5
Crouched under superimposed sheet 1 to the main lower flange of girder steel 5；
Superimposed sheet 1 reserves gap 7 along main body girder steel direction；
Gap 9 is left between superimposed sheet.
After superimposed sheet 1 installs, in the main lower flange direction formwork of girder steel 1, casting concrete, concrete grout is along gap
Flow into girder steel lower flange；
Superimposed sheet last layer 8 has been poured, and after ground surface finishing layer has been constructed, girder steel has all been rolled in floor.
It is 1000mm, spacing 500mm, gap width 50mm that the superimposed sheet reserves gap length along main body girder steel direction.
