Description
Technical field
The utility model belongs to technical field of buildings, is specifically related to the embedded composite floor system of a kind of web.
Technical background
In existing profiled sheet and the design of cast-in-situ concrete composite floor, the operating platform when permanent template when mostly being profiled sheet and conduct construction as construction.Profiled sheet has been accelerated construction speed as permanent formwork, though brought convenience to construction like this, profiled sheet is only considered structure function when construction, and in but not too big effect of operational phase, this has caused the waste of profiled sheet.
In existing steel and the concrete combination beam, adopt shear connector to realize girder steel and concrete slab compound action more.The main effect of shearing connecting piece is the longitudinal shear on opposing concrete slab and the girder steel superposed surfaces; Resist concrete slab simultaneously in addition and have the power that starts of separating the balance of power, make concrete slab become as a whole co-operation with girder steel with girder steel.Yet no matter be which kind of shears the shearing connecting pieces such as compound beam consumption peg that connect, and generation welding expense correspondingly, and the top flange of girder steel is in pressure zone under the effect of positive bending moment, the pressure zone of multidigit under the positive bending moment effect in compound beam cross section, and in fact the compression capability of concrete slab has enough been resisted the positive bending moment effect.This has also caused the waste of girder steel top flange steel plate.
At this present situation, be necessary to find out and a kind ofly can save shearing connecting piece and welding expense correspondingly, the composite floor system method for designing that can save the girder steel top flange again, to the design of existing many high-rise steel structure floor framing do one abundant and improve.
Summary of the invention
The purpose of this utility model is to provide a kind of embedded composite floor system of web of economical rationality.
The embedded composite floor system of the web that the utility model proposes, form by concrete slab 1, longitudinal stress reinforcing bar 2, girder steel, connector 5, transversely distributed steelbar 6, wherein, be provided with longitudinal stress reinforcing bar 2 and transversely distributed steelbar 6 in the concrete slab 1, girder steel is inverted T-shaped, is made up of bottom flange 3 and web 4, web 4 one ends connect bottom flange 3, other end fluting forms groove nail shear connector 5, and longitudinal stress reinforcing bar 2 passes notch, and is positioned at the two ends of notch bottom; Or web 4 other end perforates 8, the longitudinal stress reinforcing bar passes this perforate 8, and is positioned at 8 bottoms, hole.
The embedded compound beam of web that is used for secondary beam in the utility model, being connected to of itself and girder is hinged.
In the utility model, to the web embedded compound beam of slotting, the longitudinal stress reinforcing bar passes notch, and is positioned at the two ends of notch bottom; To the embedded compound beam of web perforate,, the longitudinal stress reinforcing bar passes this perforate, and is positioned at the bottom, hole.
The embedded composite floor system of the web that the utility model proposes, its preparation method have two kinds:
One, as shown in Figure 1, the slot making of embedded composite floor system of web, its making step is;
1) pushes down the depth of section of T steel beam, make a high web i section steel beam as shown in Figure 2, cut into required form, form two inverted T-shaped girder steels along web middle part line of cut 7.
2) as shown in Figure 1, by structure construction drawing requirement location, consider the degree of depth that web embeds to the inverted T-shaped girder steel.
3) be that steel bar stress is worn at two ends, notch bottom in the space of groove nail, fluid concrete forms composite floor system then.
Two making as the embedded compound beam of web perforate of Fig. 3, its making step is;
1) in web 4 top perforates, the web 4 and the edge of a wing 3 are welded together to form the inverted T-shaped cross section.
2) wear the concrete slab steel bar stress in the bottom, aperture, fluid concrete forms compound beam then.
In the utility model, form shear connector by the web tooth punching groove of inverted T-shaped girder steel or perforate and resist the straight skidding of compound beam and vertically start.
In the utility model, the shear connector that is formed by web fluting or perforate has higher shear-carrying capacity, is easy to realize that the complete shearing resistance of compound beam connects.
In the utility model, the freely-supported form is adopted at the embedded compound beam of the web two ends that are used for secondary beam.
The embedded composite floor system of web in the utility model is compared the top flange of having saved girder steel with common composite floor system, compares the saving steel with the common composite floor system of identical span and same bearer ability and can reach 20%～30%.
The composite floor system system that adopts the embedded composite floor system of web in the utility model to form is compared with the common composite floor system system that adopts peg, has saved peg and corresponding welding expense, can save 6～10 of pegs for every square metre.
The embedded composite floor system of web in the utility model can be used for the multi-rise building superstructure.Also can be used for the freely-supported platform that bridge construction and other structure are used to bear transverse load.
