Description
Technical field：
The invention belongs to house all-in-one technical fields, are related to building prefabricated components, and in particular to a kind of close rib of truss-like
Hollow superposed floor.
Background technology：
As the developing direction of Future Residential Housing, prefabricated concrete structure is to carry out the main of building industrialization energetically
Trend.For floor framing as structural bearing component, main function is that the vertical load of flooring is passed to beam column, therefore in structure
There is important connection, stress effect, and with larger construction volume in entirety, therefore realize the reasonable assembling of superstructure to knot
Structure stress and construction have important meaning.
At present common superposed floor there are some it is universal the problem of：First is single load bearing superstructure, can not be realized larger
Two-way span.Second, Prefabricated stacking floor thickness is thin, rigidity is small, and damaged, phenomenon of rupture easily occurs in way in transport, lifting,
Some superposed floors is avoid this problem, the pre-buried triangular reinforced bar truss in precast floor slab, but it is as girt strip reinforcing steel bar bear
Poor performance.Third, the overlapping layers poured on precast floor slab is mostly solid, from great, strongly limits span.
For this purpose, the present invention proposes a kind of hollow superposed floor of close rib of rectangle truss-like, it is firm with bidirectional stress, precast floor slab
Degree is big, rectangle steel bar girder accepts the advantages that reasonable, dead weight is small, rigidity is big as girt strip reinforcing bar, solves problem above together.

In plate, conventional beam muscle 9 is bound, 7 concrete of bottom plate is poured, the precast floor slab 1 is made after maintenance.
(2) several blocks of precast floor slabs 1 are lifted and supports the precast floor slab at 6 both ends of rectangle steel bar girder, made
Make template at piece 5, bind the connection reinforcing bar that each 1 side of precast floor slab is stretched out, the rectangle reinforcing bar purlin of welding adjacent floor deck docking
Frame 6 and conventional beam muscle 9 reserve the position placement foamed concrete block 4 of the first girt strip 2, the second girt strip 8, in foamed concrete block 4
Top binds 3 two-way concrete slab of top plate, and the connection reinforcing bar of precast floor slab side is anchored into surrounding precast beam or surrounding precast beam wall,
Pour piece 5,3 concrete of the first girt strip 2, the second girt strip 8 and top plate so that different precast floor slabs 1 form entirety, are overlapped into institute
State the hollow superposed floor of the close rib of truss-like.
Equipped with two-way long slab muscle in the precast floor slab 1, and stretch out 1 side a distance of precast floor slab.
The lower surface of the precast floor slab 1 is smooth, and upper surface and side are crude face.
The precast floor slab 1 is placed in checkerboard.
The rectangle steel bar girder 6 and conventional beam muscle 9 stretch out a distance outside 1 side of precast floor slab.
The rectangle steel bar girder 6 forms close rib with the conventional 9 two-way equidistant placement of beam muscle.
The hollow superposed floor of the close rib of the truss-like, it is characterised in that two-way slab muscle is configured in the top plate 3.
The foamed concrete block 4 is used as the bed die of first girt strip 2, the side form of the second girt strip 8 and top plate 3, institute
Foamed concrete block 4 is stated as floor thermal insulation material.
The present invention has following technical characterstic：
The hollow superposed floor construction method of the close rib of truss-like in the present invention is simple and practicable；Superstructure in the present invention it is two-way by
Power, and arrange waffle beam, it can be achieved that large span in superstructure；The rectangle steel bar girder and conventional beam muscle considerably increase prefabricated building
The rigidity of plate increases the safety of component in transport, lifting, and the compression as girt strip in superstructure and tension indulge muscle again after overlapping
And stirrup, and vertical muscle stretches out the outer a distance of precast floor slab, forms reserved steel bar, connection and superstructure and other structures between floor
Part is welded to each other, and assembled with cast-in-place concrete mode when connecting；The superstructure be hollow-core construction, hollow position filling-foam concrete
Block participates in stress and as thermal insulation material, substantially reduces dead load；Superstructure bottom is smooth, can exempt finishing furred ceiling, and all
Floor pipeline and drainage elbow can be embedded in superstructure in advance, increase interior net storey height and beauty；Novel superstructure is assembled flexibly, each prefabricated
Floor junction template consumption is few, and precast floor slab form is few, easy for construction, economical and practical.
