ysteel concrete orthogonal-diagonal lattice space lattice box structure of the long narrow shape plane of > 1.5 and preparation method thereof, belongs to building structure technology field.
Background technology
On May 22nd, 2014, Ministry of Land and Resources issues " The Ministry of Land and Resources of the People's Republic of China, MOLR makes " namely " Energy-efficient routing soil regulation " (No. 61), to large span (L
y=18m-30m) public and industrial construction, do not remake single span individual layer and multispan individual layer, and single span multilayer and multispan multilayer will be made, adopt traditional reinforced concrete frame structure, not only " Seismic Design of Building code " (GB50011-2010) has clear stipulaties, this is steel concrete conventional frame structure " maybe should should not to make single span multilayer ", keeps away unavoidable defect.
Example: when building is single span multilayer (4 layers), its long limit L
x=54m, minor face span L
y=27m, i.e. L
x/ L
ywhen=2, Zhou Bianzhu net is 9m, and now the every one deck in span direction only has 4 posts, 3 beams, and the anti-side rigidity of frame construction far from meets " seismic design provision in building code " (GB50011-2010) requirement; Adopt the superstructure of orthogonal spatial box structure, superstructure also can be caused along span direction more than 80% load, and transmit the minimum generation making structure stress non-uniform phenomenon along long to load.
Summary of the invention
The problem to be solved in the present invention is for above deficiency, provides a kind of steel concrete orthogonal-diagonal lattice space lattice box structure, after adopting this grid box structure, realizes following object:
1, anti-side rigidity is improved: crossbeam and post are rigidly connected, at identical horizontal force
punder effect, its anti-side rigidity improves 4 times; After gridding, periphery grid type framework is in the constant situation in cross section, and its anti-side rigidity improves 90 times.
2, save construction costs: reduce 25%-30% than large-span frame structure material, the hollow sandwich board concrete of superstructure and steel reduce more than 25%-30% or higher.
3, structure stress is even, can not form orthogonal spatial box structure superstructure along span direction more than 80% load, and occurs along long to the minimum structure stress non-uniform phenomenon that makes of load transmission.
4, a kind of preparation method of steel concrete orthogonal-diagonal lattice space lattice box structure is provided.
For solving above technical problem, the present invention is by the following technical solutions: steel concrete orthogonal-diagonal lattice space lattice box structure, is characterized in that: upper and lower string and its periphery steel concrete grid type frame column at the laced beam two ends of building superstructure are rigidly connected.
A kind of prioritization scheme, building superstructure periphery is isosceles triangle grid, and centre peripherally 45 ° of angles is square grid on an empty stomach; Periphery isosceles triangle right-angle side size a and the long a of isosceles triangle hypotenuse

Further, orthogonal-diagonal lattice space lattice box structure, is applicable to the long limit (L of superstructure
x) and minor face (L
yi.e. span) ratio L
x/ L
ythe long narrow shape plane of > 1.5, hollow floor system thickness h=(L
y/ 25 ~ L
y/ 30), it winds up and considers that concrete slab six times of thickness (6 δ) is worked, namely wind up as T section, lower edge is still square-section, upper and lower string and the grid type frame column at these orthogonal-diagonal lattice laced beam two ends are rigidly connected, and this is the construction measure guaranteeing to be formed space lattice box structure entirety.
Further, Liangqi top chord section is T-shaped on an empty stomach, and its lower edge cross section is rectangle, its shear connector clear height h

0/ B≤1.
Further, the cross section of shear connector is cross.
Based on the above steel concrete orthogonal-diagonal lattice space lattice box structure, the preparation method of this steel concrete orthogonal-diagonal lattice space lattice box structure comprises the following steps:
1) first to construct one deck periphery steel concrete grid type frame column;
2) to construct one deck Rc Open-web Sandwich Plates superstructure, by the laced beam of one deck building superstructure and its
Periphery steel concrete grid type frame column is rigidly connected.
Further, the construction of two layers of periphery steel concrete grid type frame column is carried out;
To construct two layers of Rc Open-web Sandwich Plates superstructure, the laced beam of two layers of building superstructure and its periphery steel concrete grid type frame column are rigidly connected.
Further, the periphery steel concrete grid type frame column of other floors, the construction of Rc Open-web Sandwich Plates superstructure and connection is carried out;
By maintenance, form steel concrete orthogonal-diagonal lattice space lattice box structure.
The present invention adopts above technical scheme, compared with prior art, has the following advantages:
(1) structure stress is even, can not form orthogonal spatial box structure superstructure along span direction more than 80% load, and occurs along long to the minimum structure stress non-uniform phenomenon that makes of load transmission.
