Abstract

The invention relates to a dual-way steel-laminated slab concrete composite floor, belonging to a new large span floor structure, comprising a cross steel beam, a prefabricated slab and a later pouring concrete layer, wherein the cross steel beam is an I shaped cross section or box section steel beam; the prefabricated slab, a common reinforced concrete slab or a prestressed concrete slab, is held on the cross steel beam and covered on the grids between the steel beams; the later pouring concrete layer is concrete poured on the prefabricated slab and the steel beam. The invention has the advantages of low structure height, high bearing capacity, stiffness, bilateral support effect, saved forming procedure and formwork, reduced the wet work amounts of site concrete, favorableness to the three-dimensional construction, and shortened construction period.

Description

Bidirectional steel-stacked plate concrete composite building roof
Technical field
The present invention relates to a kind of novel building cover structure (15m≤span L≤70m), belong to the Structural Engineering field of striding greatly.
Background technology
In building structure, when the superstructure span is big, can adopt two-way concrete slab concrete girt strip type superstructure or steel concrete intersecting parallels superstructure.But, when the planar dimension of building and post apart from enlarging markedly or indoor when not allowing to establish the vertical support member, these traditional concrete floor structural forms can't satisfy the requirement of large-span structure development on supporting capacity, anti-seismic performance, speed of application.The steel work superstructure has the intensity height, from the characteristics of heavy and light, if but the girder steel in the superstructure is pressed bidirectional stress when design, the performance boost that its two-way power transmission brought is not enough to surpass or offsets the girder steel node increases the cost rising that is caused, thereby does not possess the economic technology advantage.
Summary of the invention
The object of the present invention is to provide that a kind of bearing capacity is big, easy construction, two-way supporting steel-concrete composite floor system structure that structure height is low.
Technical scheme of the present invention is as follows:
A kind of bidirectional steel-stacked plate concrete composite building roof is characterized in that: be made up of intersection girder steel 1, precast plate 3 and last layer concrete 4, and by shear connector 2 described each several part be combined into integral body; Described intersection girder steel 1 adopts i section steel beam or box steel beam, is positioned at the lower floor of superstructure; Described precast plate 3 is supported on the top flange of intersection girder steel and covers the district's lattice that intersect between girder steel; Described last layer concrete 4 is for building in the concrete of precast plate and girder steel top.
Precast plate of the present invention is ordinary reinforced concrete plate or prestressed concrete plate.In described last layer concrete, dispose reinforcing bar.
The present invention has the following advantages with respect to prior art and the high-lighting effect:
Compare with steel concrete girt strip type superstructure, steel concrete intersecting parallels superstructure, bidirectional steel-stacked plate concrete composite building roof can be saved a die process and a template, reduces on-site concrete wet trade amount, is convenient to three-dimensional construction, shortens the construction period.Compare with traditional unidirectional supporting steel-concrete composite beam superstructure, can reduce structure height greatly, improve structural bearing capacity and rigidity.
Description of drawings
Fig. 1 is the schematic perspective view of intersection girder steel among the present invention.
Fig. 2 installs schematic perspective view behind the precast plate for construction stage of the present invention.
Fig. 3 builds the concrete schematic perspective view of last layer in the embodiment of the present invention.
Among the figure: 1-intersects girder steel; The 2-shear connector; The 3-precast plate; 4-last layer concrete.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
Bidirectional steel-stacked plate concrete composite building roof provided by the invention is made up of intersection girder steel 1, precast plate 3 and last layer concrete 4 three parts, and by shear connector 2 each several part is combined into whole co-operation.The girder steel 1 that intersects can be i section steel beam or box steel beam, is positioned at the lower floor of superstructure; The connected mode of intersection girder steel can adopt bolt to connect or welding manner, and girder steel quantity, sectional dimension and girder steel spacing are determined according to instructions for use.Shear connector 2 can be forms such as peg, channel-section steel, is with girder steel and the concrete slab cooperative parts that link together.Precast plate 3 upper surfaces and side should be matsurface, with the combination degree of raising with last layer concrete 4; Precast plate 3 is supported on the top flange of intersection girder steel and covers the district's lattice that intersect between girder steel, and lap length is not less than 5cm; Precast plate 3 can be ordinary reinforced concrete plate or prestressed concrete slabs; The thickness of precast plate 3 should determine according to the spacing of girder steel, when thin or precast plate span satisfies deformation requirements in the work progress more greatly and not when precast plate 3, should 3 times temporary support be set at precast plate in the construction.Last layer concrete 4 is for building in the concrete of precast plate and girder steel top; Build last layer concrete 4 and should guarantee the concrete density in notch place.For prevent to shrink, thermal cracking and from the stressed angle of floor, last layer concrete 4 planted agents dispose the reinforcing bar of some.
Working procedure of the present invention is:
(1) makes girder steel and welding shear connector 2 in factory process;
(2) the on-the-spot intersection girder steel 1 of installing;
(3) after intersection girder steel 1 installation in position, precast plate 3 is installed on girder steel;
(4) install after the precast plate 3 colligation last layer reinforcing bar and build last layer concrete 4.
