Specific embodiment
Here is that the present invention is further described in conjunction with the accompanying drawings and embodiments.
Embodiment one
With reference to Fig. 1 and Fig. 4, the bolumn cap radiation novel floor system of cross coupling including multiple bolumn caps 1, radiates beam and sketch plate
2.The economic span of the utility model floor system is 8-12 meters, when span is 8-10 meters, can set oblique friendship in middle region panel
Pitch beam.
Bolumn cap 1 is separately mounted to the top of column 3, and radiates beam as diagonal cross beam 5, and diagonal cross beam 5 is mounted on column
The periphery of cap 1, wherein bolumn cap 1 can be rectangle, circle or polygon.Multiple bolumn caps 1 divide to be arranged for transversely arranged bolumn cap and longitudinal direction
Colonnade cap, transversely arranged bolumn cap and longitudinal arrangement bolumn cap are uniformly distributed, and every four bolumn caps 1 form the Installation of beam slab of square structure
Gap 4, the both ends of diagonal cross beam 5 are connected on the diagonal in the Installation of beam slab gap 4 that every four bolumn caps 1 are formed, different
Shape plate 2 is mounted in Installation of beam slab gap 4, and is not connect with adjacent two bolumn cap 1 and diagonal cross beam 5, and entire floor system leads to
Diagonal cross beam 5 is crossed to connect to form fenestral fabric with bolumn cap 1.The economic size dimension of bolumn cap 1 is about 0.4-0.5 times of column across ruler
It is very little, the span of beam is substantially reduced in this way, reduces deck-molding, and considerably reduce the arrangement of reinforcement of beam.Pass through setting for diagonal cross beam 5
It puts, the perimeter of sketch plate 2 is longer, span smaller, realizes that diagonal cross beam 5 to floor area lattice classifying rationally, considerably reduces
The quantity of reinforcement and cost of floor.
In addition, the tie point of diagonal cross beam 5 and bolumn cap 1 forms plastic hinge 6, floor system of the present invention with it is other existing each
Kind floor system is compared, it is easier to have the plastic hinge 6 conducive to energy dissipation in beam-ends, it is strong both to have realized current specifications in this way
The shockproof requirements of the weak beam of column, and with good anti-seismic performance.Floor system of the present invention is suitable for megastore, garage parking, does
Public building, multi storied industrial factory building, library, the large spans public buildings such as building and underground garage, civil air defense constructions and installations of storing in a warehouse.
Embodiment two
With reference to Fig. 3, the bolumn cap radiation novel floor system of cross coupling including multiple bolumn caps 1, radiates beam and sketch plate 2.Other
It is identical with embodiment one, the difference lies in：The economic span of the utility model floor system is 8-12 meters, when span is 10-12 meters
When, in addition in middle region panel, that is, Installation of beam slab gap 4 diagonal cross beam can be set, while also set up positive cross coupling 7.
Wherein, positive cross coupling 7 is connected between adjacent two bolumn cap 1, and the both ends of positive cross coupling 7 respectively with bolumn cap 1
Midpoint connection, beam-ends is made easily to be formed in this way conducive to energy dissipation plastic hinge 6, and quantity is other existing floor systems
2 times because setting diagonal cross beam 5 and positive cross coupling 7 simultaneously, realize the shockproof requirements of strong column and weak beam.The utility model building
Cover system improves the anti-seismic performance of structure, especially collapse resistant capacity.
Experimental example：
Example 1：With reference to Fig. 1, the novel superstructure body of cross coupling is radiated using bolumn cap by Underground Garage Pillar Net size 8.4mX8.4m
It is that tablet bolumn cap, size 3.5mX3.5m, thickness 500mm, the sectional dimension of diagonal cross beam are set on column
250mmX500mm (contains plate thickness), and plate thickness 250mm (is illustrated) see Fig. 1.
Example 2：Underground Garage Pillar Net size 8.4mX8.4m, with reference to Fig. 2, using beam-and-slab floor system (with other existing buildings
Cover system steel using amount and concrete amount are suitable), the sectional dimension 400mmX800mm (containing plate thickness) of beam, plate thickness 350mm are calculated
Span (illustrates) for 8.4m see Fig. 2.
Amount of reinforcement contrast table：
Note：Design load using conventional top plate of underground parking garage is about 40kN/ ㎡.
Concrete amount contrast table：
So as seen from the above table：
(1) project cost is greatly reduced.Pass through the Underground Garage Floor System theory analysis to commonly using column net 8.4mX8.4m
And FEM calculation, degree of safety is identical, under clear height same case, floor system of the present invention and other various existing floor systems
It compares, reinforcing bar amount averagely saves more than 50%, and amount of concrete averagely saves more than 20%, and structural cost saves more than 35%.
(2) due to reducing depth of beam, in the case where clear height is identical, the utility model floor system is than beam-and-slab floor system
Floor height reduces about 300mm-400mm, and cost reduces more than 10%.
(3) there is good anti-seismic performance.Beam-ends is easily formed with the plastic hinge conducive to energy dissipation, and quantity is other
1~2 times (while setting oblique and positive cross coupling) of existing floor system realizes the shockproof requirements of strong column and weak beam.This is new
Type floor system improves the anti-seismic performance of structure, especially top collapse resistant capacity.
The economic span of the present invention is 8-12 meters, when span is 8-10 meters, can set diagonal cross in middle region panel
Beam 5；When span is 10-12 meters, while diagonal cross beam 5 and positive cross coupling 7 are set.By setting bolumn cap on column 3
1, the span of beam is reduced, Installation of beam slab gap 4 is divided into the longer sketch plate of perimeter by the setting for radiating beam, is greatly lowered
The quantity of reinforcement and cost of superstructure.
The present invention is not limited to above-mentioned embodiment, in the knowledge having in those skilled in the art, may be used also
To be made a variety of changes under the premise of present inventive concept is not departed from, the content after variation still falls within protection scope of the present invention.
