Description
Technical field
The present invention relates to a kind of floor framing system prefabricated components, particularly relate to a kind of full Prefabricated Concrete building for building
Plate.
Background technology
The floor system of existing prefabricated buildings structure can be divided into cast-in-place concrete building roof, profiled sheet to combine building
Lid, steel bar girder composite floor system, concrete folding panel ceiling for storied building, its shortcoming is that Contraction in Site amount is big (a large amount of
Use template, reinforcing bar, scaffold etc.), on-the-spot operator is many, and speed of application is slow, produces bigger ring
Environment pollution, costly, energy-conserving and environment-protective index is relatively low in security protection.
The multi-porous precast slab in the past used, collapses owing to it easily comes off under the horizontal force of earthquake, wind etc.,
It is prohibited from using.
Fabricated construction floor system, in addition to meeting stress and structural integrity, still should ensure that in horizontal loads
Under do not collapse, the requirement that field operation amount is few.
Summary of the invention
In consideration of it, the technical problem to be solved is: provide a kind of full Prefabricated Concrete floor for building, energy
Preferably solve problem present in package assembly, make Contraction in Site workload minimize.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that
Precast floor slab is disposably at factory's moulding by casting, and upper and lower surface is smooth, by configuration reinforcement 1 and stretch into beam
In (exceeding beam centrage), reinforcing bar 3 stretch in U-shaped beam and under bend into anchoring in U-shaped beam, pour U-shaped beam
After the concrete of post-cast strip, form an entirety.Certain length is stretched out outside plate width in the every side of reinforcing bar 2,4 muscle,
Arranging last-cost joint or being shelved on the U-shaped beam parallel with length direction between plate width, pours last-cost joint coagulation
Form an entirety after soil, be jointly forced into floor system.
Full precoated plate completes at factory's once-cast, the smooth formation in top and bottom structure stress plate.
Reinforcing bar 3 stretch in U-shaped beam and under bend in U-shaped beam, be anchored in the rear pouring concrete of U-shaped beam, protect
Card floor does not fall off under level vertical load effect effect and collapses.
Reinforcing bar 3 stretch in U-shaped beam and under bend in U-shaped beam, be anchored in the rear pouring concrete of U-shaped beam, make
Precast floor slab can undertake the plate face built in operational phase generation and bear square.
Floor, after pouring U-shaped sill bolt, plate seam width after-pouring concrete, forms integral floor system, transmission
Architectural vertical and lateral load.
Reinforcing bar 3 stretch in U-shaped beam and under bend into anchoring in U-shaped beam, for strengthening the horizontal steel that anchoring property is arranged
Muscle 6.
The Ban Di support zone local reduction thickness of slab of precoated plate, it is ensured that absolute altitude at the bottom of U steel beam flange plate and precoated plate
At the bottom of plate, absolute altitude is consistent.
The connection of precoated plate and steel plate shear force wall, it is ensured that can effectively transmit between precoated plate and shear wall vertical force and
Horizontal shear.
Pipeline for building is directly embedded in precoated plate, completes in factory, forms Highgrade integration product,
Reduce the work at scene to greatest extent.
For the position that pipeline is the most intensive, use the precoated plate of half thickness, after pipeline lay completes, in advance
Making sheet face pours the floor (overlapping layers) of other half thickness, and remaining structure is consistent with full precoated plate.
The beneficial effects of the present invention is:
1, by rational anchor Design, it is ensured that precoated plate and structural framework entirety stress, can resist vertically with
Horizontal load action, safe and reliable.
2, concentrate on the prefabrication plate stage and complete by reasonably designing the pipeline that can would be required to be embedded in plate,
Highly integrated.
3, work on the spot amount is down to floor level, it is ensured that installation rate and be greatly shortened the completion of works time.

Detailed description of the invention
Describe the preferred embodiments of the present invention below in conjunction with the accompanying drawings in detail.
Refer to Fig. 1-4, present invention is disclosed a kind of full Prefabricated Concrete floor for building.
Preferably, full Prefabricated Concrete floor installation process includes:
A., steel structure column and U-shaped girder steel 102 (including beams of concrete) are installed.
B., full Prefabricated Concrete floor 101 is installed on U-shaped girder steel 102.
When C. having steel plate shear force wall, by the shaped steel 106 that is embedded in full Prefabricated Concrete floor 101 (such as channel-section steel, angle
Steel etc.) it is shelved on angle steel 107, it is welded and fixed with steel plate shear force wall 105 simultaneously, reinforcing bar 3 is cut with steel plate
Power wall 105 is welded and fixed.
D. pouring concrete 103 after pouring between sill bolt concrete, plate seam.
The most in Figure 5, when there is floor on the right, construct as the left side.
