Abstract
The utility model relates to a cantilever beam component with high load-bearing capacity. A steel truss is arranged in a reinforced concrete column; the steel truss comprises upper and lower chord members which are parallel to each other; a vertical web member and a crossed inclined web member are arranged between the upper and the lower chord members. The cantilever beam with an inner steel truss is adopted for remarkably improving the load bearing capacity of the beam, is large in rigidity and small in deformation, so that the beam height is effectively reduced and the overhanging distance of the beam is increased. Meanwhile, the cantilever beam with the steel truss has excellent seismic resistance and good structural ductility, and can be used for sufficiently bringing the advantages of the steel structure into play.
Description
Technical field
The utility model relates to a kind of Cantilever Beams member, belongs to the building structure technology field.
Background technology
Raising along with socioeconomic development and people's living standard, people are also more and more higher to the attractive in appearance and functional requirement of building, various planes and facade irregular high-rise buildings are also enriching the construction in city more and more, it is more extensive that large cantilevered structure is used, this with regard to require the structural engineer to overall structure system and each substantially the mechanical relationship between minute system thorough understanding is arranged, use new material and structure, cooperate the architect, design gratifying building.Adopt the ordinary reinforced concrete Cantilever Beams, depth of section directly need to calculate gained by strength and stiffness.But the method often is subject to elevation of building restriction, and the Cantilever Beams height has certain limitation, just can adopt when only all not too large for encorbelment span and load, and limitation is larger.
One of form of structure of steel reinforced concrete (SRC) structure structure Shi Changyong, it is a kind of principal mode of steel-concrete combined structure, its supporting capacity can be higher than the supporting capacity of reinforced concrete member of same profile more than 1 times, can reduce the sectional area of member, increase usable floor area and the space of building structure, produce preferably economic benefit.Because much more more and more its supporting capacity is high, rigidity reaches greatly the advantages such as anti-seismic performance is good, be applied to highrise building and the super highrise building of large-span structure.But the structural steel amount is large, and reinforcing bar and concrete binding power are relatively poor, needs to increase special crab-bolt and improves reinforcing bar and concrete adhesive property.A kind of inside that the present invention just is being based on above technical background proposition is the new structure of the Cantilever Beams member of steel truss.
Summary of the invention
The purpose of this utility model provides a kind of high-bearing Cantilever Beams member, and this element bearing capacity is high, rigidity is large, distortion is little, and cost is low, can effectively reduce deck-molding, increases the distance of encorbelmenting of beam.
The technical scheme that the utility model is taked is:
A kind of high-bearing Cantilever Beams member is provided with steel truss in reinforced concrete post, steel truss comprises the upper and lower chord member that is parallel to each other, and is provided with the diagonal web member of perpendicular web member and intersection between the upper and lower chord member.
The diagonal web member alternative arrangement of described perpendicular web member, intersection arranges.
Perpendicular web member and diagonal web member are welded on upper chord and the lower chord.
Steel truss can be used round steel pipe, H shaped steel, angle steel etc.
Effect of the present utility model is:
1, adopt inside to significantly improve Load-bearing capacity of beam for the Cantilever Beams of steel truss, its rigidity is large, distortion is little, effectively reduces deck-molding, has increased the distance of encorbelmenting of beam.
2, the Cantilever Beams of steel truss has good anti-seismic performance, and good structure ductility is given full play to the advantage of steel work.
3, the Cantilever Beams of steel truss can be adjusted flexibly according to the depth of section of beam the height of steel truss in the beam, has greatly reduced rolled steel dosage, saves cost.
Description of drawings
Fig. 1 is the utility model embodiment 1 Cantilever Beams form schematic diagram;
Fig. 2 is the A-A sectional view among Fig. 1;
Wherein, 1. upper chord, 2. lower chord, 3. perpendicular web member, 4. diagonal web member, 5. concrete, 6. concrete reinforcement, 7. concrete lacing wire.
The specific embodiment
Below in conjunction with accompanying drawing this practical patent is elaborated:
Embodiment 1
Contrast Fig. 1, a kind of high-bearing Cantilever Beams member is provided with steel truss in reinforced concrete post, and steel truss comprises upper 1, the lower chord 2 that is parallel to each other, the diagonal web member 4 that is provided with perpendicular web member 3 between the upper and lower chord member and intersects.
Described perpendicular web member 3, the diagonal web member 4 alternative arrangement settings that intersect.
Perpendicular web member 3 and diagonal web member 4 are welded on upper chord 1 and the lower chord 2.
Steel truss can be round steel pipe, H shaped steel, angle steel uniform section form.The steel truss of Cantilever Beams stretches into styletable length and is 0.9 times of this direction column section width.
