Description
Technical field
The present invention relates to a kind of cross-shaped steel component.
Background technology
Steel construction industrialization degree is high, and stress performance is good, applies more and more extensive in building structure.Shear wall bearing capacity
Height, anti-side rigidity is big, is the main lateral resisting structure component of high-level structure.
The combined member cross sections such as steel core concrete column are generally square or circular, give full play to the binding effect of steel pipe.
Steel concrete compound shear wall has the performance advantage of shear wall, has again making and the installation advantage of steel construction；Steel-coagulation
The ratio on the long and short limit in the cross section of local soil type's combination shearing wall is more than 1, and the binding effect of steel reduces, and typically can incite somebody to action by arranging dividing plate
Component separates, and forms steel pipe bundle；Owing to dividing plate is difficult to connect at interlayer, so its stress performance cannot give full play to.Application
Number it is that 201410018360.4 patents disclose a kind of cross-shaped steel pipe bundle combinations structure, the factory steel pipe bundle made and building site
Cast in situs concrete composition in steel pipe bundle, the dividing plate of steel pipe bundle connects the edge of a wing, and welding capacity is big, and steel quantity consumption is high；Carrier ring
Between be difficult to solder to, stress performance cannot give full play to；And concrete cast in situs, the amount of pouring is big, reduces prefabricated rate；Pour
After concrete, concrete separating is opened by dividing plate, is unfavorable for globality.
Summary of the invention
In order to solve, existing steel beam column steel using amount is big, welding job amount concrete globality that is big and that pour in it is poor
Deficiency, the present invention provides a kind of cross-shaped steel component.
The technical scheme is that described cross-shaped steel component includes that outline is cross steel part and connector,
Described connector is connected on the steel plate of steel part long limit, and offside connector overlaps.Described connector is made up of rod iron；Or
Described connector is made up of deformed bar；Or described connector is made up of strip steel plate etc..Described connector is U-shaped, two limbs
It is connected on steel part, or connector is other shapes.Two limb lateral arrangement of described U-shaped connector, or the connection of described U-shaped
Two limbs of part are longitudinally arranged.
The connector overlapping regions of described cross-shaped steel component is inserted into longitudinal reinforcement, constitutes skeleton with connector, improves
The connector drawknot ability to steel plate, facilitates interlayer to connect.
Described cross-shaped steel component includes that cross steel part and connector, described steel part long limit steel plate are arranged and longitudinally puts more energy into
Rib, described connector is connected on longitudinal stiffener, and offside connector overlaps.
Described cross-shaped steel component includes that outline is cross steel part and connector, and described steel part connected piece is divided into
More than one region, has poured concrete (need to arrange template during casting concrete in steel part) in subregion.Concrete can
Pour at the scene；Or pour at concrete plant, make prefabricated component together with steel beam column；Or the concrete in subregion
Pouring in factory, make prefabricated component together with steel beam column, remainder pours at the scene.The concrete that factory pours improves steel
The rigidity of component long limit steel plate, steel plate deformed when preventing transport, lifting, poured in place concrete, and improve steel beam column
Bearing capacity, it is ensured that working security.
When factory's casting concrete, described connector is not cast in concrete, the steel precast concrete of formation
After molectron transports scene, then pour into concrete, the globality of pouring concrete after raising, and be conveniently inserted at connector
Vertical muscle, it is achieved interlayer stress is continuous.
A kind of manufacture method of steel beam column of the present invention is, first makes steel part long limit steel plate, is welded to connect on the steel plate of long limit
Then two long limit steel plates are made connector overlap, weld at steel plate two ends, long limit by part (or welding longitudinal stiffener) relatively
Steel plate.
The present invention compared with prior art has the advantage that.
(1) welding job amount and the steel using amount of steel beam column are reduced.In prior art, the dividing plate of cross-shaped steel component is steel
Plate, welding job amount is big, and steel using amount is high；The connectors such as present invention steel pole replace part or all of steel plate dividing plate, reduce welding
Workload and steel using amount.
(2) behavior of members under loading is improved.In prior art, in steel beam column, casting concrete forms steel-concrete combination
Component；Steel beam column dividing plate interlayer cannot be welded to connect, and clapboard stress is difficult to continuously, and dividing plate only plays connection, the long limit of steel part of putting more energy into
The effect of steel plate, it is impossible to play dividing plate steel performance；The connectors such as present invention steel pole connect steel part long limit steel plate, and interlayer passes through
It is continuous that vertical muscle is set, improves component performance.
(3) binding ability of concrete and steel beam column is improved.In prior art, in steel beam column, casting concrete is formed
Steel-concrete combined member, concrete separating is opened by steel plate dividing plate, reduces the globality of concrete；With connectors such as steel poles
Replacing steel plate dividing plate, the concrete in steel beam column is overall, significantly improves the binding ability of concrete globality and steel beam column.
(4) rigidity and the bearing capacity of steel beam column are improved.By arranging longitudinal stiffener, significantly improve the carrying of steel beam column
Power；And ribbed stiffener improves the rigidity of steel beam column long limit steel plate, prevent the steel plate when casting concrete from bloating.
(5) restriction ability to concrete is ensured.Connector connects long limit steel plate, retrains its interior concrete together；Close
Under reason design, connector can be close to steel diaphragm to the binding effect of concrete.
(6) stability of steel plate is ensured.Connector one end is anchored in concrete, other end drawknot steel plate, it is ensured that steel plate
Stability；Offside connector overlaps, and further increases the stability of steel plate；And easy to make, offside steel plate is respectively
Welded connections, then connector overlap joint is got up, it is to avoid connector two ends are respectively welded on offside steel plate by prior art
The trouble brought.
(7) in component, concrete obligatory point is formed.Offside U-shaped connector overlaps, the coagulation in the range of overlap joint
Soil connected piece constraint is got up, and when the spacing of connector is less, will form concrete obligatory point in component, has good
Performance；And strengthen connector anchoring property in concrete, indirectly add and steel plate is socketed power.
(8) construction industry level is improved.The part concrete of component of the present invention has poured in factory, it is to avoid existing
There is the deficiency that technology concrete pours at building-site, improve construction industry level.
Cross-shaped steel component of the present invention can be used for vertical supporting member, also can be used for other structural elements.
