Description
【Technical field】
The present invention relates to a kind of floor, and in particular to a kind of special full precast floor slab of assembling type steel structure, belongs to assembled
Technical field of buildings.
【Background technology】
Under the pushing of national policy, assembling type steel structure building has turned into the trend of development, and current domestic steel construction is certainly
Body structure system relative maturity, but it is relative with the three plate body system enclosing Techniques that steel construction matches backward.
As one of three plate body systems floor system, the way of existing floor of steel structure mainly has following several：1st, it is traditional
Live branch module and cast-in-situ, not only there are substantial amounts of scaffold support, formwork, live reinforcing bar colligation operation and the wet work of on-site concrete
Industry, and need to wait next layer to conserve, can just pour last layer, arduously take a lot of work and influence construction speed；2nd, profiled sheet
Concrete combined floor, high with 51~76mm ribs, rough superstructure resident family is difficult to receive, can only be by furred ceiling at
Reason, while bottom steel plate participates in stress, it is impossible to remove, its fire retardant anticorrosion problem is difficult to solve, Er Qiexian as permanent formwork
Field reinforcing bar colligation workload is still larger, is unsatisfactory for " prefabricated construction " construction requirement；3rd, steel bar truss floor support plate, in steel construction
When being applied in residential housing, because superstructure ceiling is plastered rendering processing, steel plate bed die need to be removed, former bed die and truss erect
Muscle spot welding when being connected to dismounting can only outer power destroy, laborious work consuming in demolishing process, in the costly situation of current manual
Under, dismounting cost is higher, and bed die can not recycle, and also increase certain cost；4th, reinforced concrete slab mostly should
For assembly concrete engineering, and a large amount of live reinforcing bar colligations and wet trade are thrown away, simultaneously because it does with steel structure connection
Method does not have good solution, limits its application and development in structural steelwork.
Therefore, it is in order to solve the above technical problems, special complete prefabricated it is necessory to provide a kind of assembling type steel structure of innovation
Floor, to overcome the defect of the prior art.
【The content of the invention】
To solve the above problems, it is an object of the invention to provide one kind to exempt from formwork supporting plate, exempt to tear the assembled steel knot of bed die open
The special full precast floor slab of structure, it is consolidated with steel structure connection, and situ wet operation is less, and can realize that batch production is prefabricated, live steel
Muscle colligation amount is less.
To achieve the above object, the technical scheme taken of the present invention is：A kind of special full precast floor slab of assembling type steel structure,
It is arranged on girder steel, and it includes steel bar girder, gluten, bottom muscle, built-in fitting and concrete layer；Wherein, the reinforcing bar
Truss includes wind up reinforcing bar, lower edge reinforcing bar and bearing rod；It is described wind up reinforcing bar and lower edge reinforcing bar it is arranged in parallel, and in etc.
Lumbar triangle shape is arranged；And reinforcing bar and the lower edge reinforcing bar of winding up welds with bearing rod upper and lower side respectively；The bearing rod is between waiting
Away from arrangement；Together with the gluten and the reinforcing bar colligation of winding up of steel bar girder, and and the reinforcing bar that winds up it is perpendicular；The bottom muscle and steel
The lower edge reinforcing bar colligation of muscle truss is together, and perpendicular with lower edge reinforcing bar；The steel bar girder, gluten, bottom muscle, built-in fitting point
It is not embedded in advance in concrete layer；The built-in fitting is connected with girder steel.
The special full precast floor slab of assembling type steel structure of the present invention is further arranged to：The built-in fitting includes embedded iron parts
And anchor rib；The embedded iron parts are connected on girder steel；The anchor rib part is embedded in concrete layer, and its top is outer
Stretch out concrete layer.
The special full precast floor slab of assembling type steel structure of the present invention is further arranged to：The embedded iron parts and girder steel use
It is welded to connect or bolt connection.
The special full precast floor slab of assembling type steel structure of the present invention is further arranged to：The bearing rod is in inverted v-shaped.
The special full precast floor slab of assembling type steel structure of the present invention is further arranged to：The assembling type steel structure is special complete pre-
The lap of splice of floor and girder steel processed is preferably 50~100mm.
The special full precast floor slab of assembling type steel structure of the present invention is also configured to：The crotch angle A of the anchor rib is 90 °
Or 135 °, curved rear straight section length should take 12d and 5d respectively, and crotch internal diameter should take 4d.
Compared with prior art, the present invention has the advantages that：
1. not having to formwork supporting plate, shorten the construction period；
2. without dismounting bed die, shorten the duration, reduce cost of labor, reduce Master Cost；
3. connection is reliable, structural integrity is stronger；
4. not having to colligation bottom muscle, field operation is reduced, construction quality can better control over, and shorten the duration；
5. pre-buried line box and spool, reducing field operation, construction quality can better control over, and shorten the duration；
6. floor overwhelming majority prefabrication is good, scene only pours seam post-cast strip, reduces a large amount of wet trades in scene, both
Quality is ensure that, shortens the duration again.
