【Technical field】
The utility model is related to a kind of floors, and in particular to a kind of special full precast floor slab of assembling type steel structure belongs to dress
With formula technical field of buildings.
【Background technology】
Under the pushing of national policy, assembling type steel structure builds the trend for having become development, and current country's steel construction is certainly
Body structure system relative maturity, but it is opposite 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 is mainly the following：1, traditional
Live branch module and cast-in-situ not only has a large amount of scaffold support, formwork, live reinforcing bar binding operation and the wet work of on-site concrete
Industry, and need to wait for next layer to conserve, last layer can be just poured, arduously takes a lot of work and influences construction speed；2, 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, cannot remove, fire retardant anticorrosion problem is difficult to solve, Er Qiexian as permanent formwork
Field reinforcing bar binding workload is still larger, is unsatisfactory for " prefabricated construction " construction requirement；3, steel bar truss floor support plate, in steel construction
In application, since superstructure ceiling does plastering painting processing in residential housing, steel plate bed die need to be removed, former bed die is erected with truss
Muscle spot welding can only destroy when being connected to dismounting by external force, laborious work consuming in demolishing process, in the costly situation of current manual
Under, dismounting cost is higher, and bed die cannot recycle, and also increase certain cost；4, reinforced concrete slab is answered mostly
For assembly concrete engineering, and a large amount of live reinforcing bar bindings and wet construction 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, in order to solve the above technical problems, it is special complete prefabricated it is necessory to provide a kind of assembling type steel structure of innovation
Floor, to overcome the defect in the prior art.

Using being welded to connect or be bolted.
The special full precast floor slab of assembling type steel structure of the utility model is further arranged to：The bearing rod is in the word of falling V
Shape.
The special full precast floor slab of assembling type steel structure of the utility model is further arranged to：The assembling type steel structure is special
The lap of splice of full precast floor slab and girder steel is preferably 50~100mm.
The special full precast floor slab of assembling type steel structure of the utility model is also configured to：The crotch angle A of the anchor rib
It it is 90 ° or 135 °, curved rear straight section length should take 12d and 5d, crotch internal diameter that should take 4d respectively.
Compared with prior art, the utility model has the advantages that：
1. not having to formwork supporting plate, shorten the construction period；
2. without dismounting bed die, shorten the construction period, reduce cost of labor, reduces Master Cost；
3. connection is reliable, structural integrity is stronger；
4. without binding bottom muscle, field operation is reduced, construction quality can be controlled preferably, be shortened the construction period；
5. pre-buried wire box and spool, reduce field operation, construction quality can be controlled preferably, be shortened the construction period；
6. floor overwhelming majority prefabrication is good, scene only pours seam post-cast strip, reduces a large amount of wet constructions in scene, both
It ensure that quality, and shorten the duration.
