The connecting pieces are connected with steel plates on the long edges of the steel piece. The connecting pieces are in a U shape. The U-shaped connecting pieces on the opposite sides are in lap joint. By means of the L-shaped steel member, the structural stress performance and the industrial level are improved.
Description
Technical field
The present invention relates to a kind of L-type steel beam column.
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 disclose a kind of L shaped steel tube bank combinative structure for 201410017711.X patent, factory the steel pipe bundle made and building site are existing
Field pours the concrete composition in steel pipe bundle, and the dividing plate of steel pipe bundle connects the edge of a wing, and welding capacity is big, and steel quantity consumption is high；Dividing plate interlayer
Being 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 mixed
After solidifying soil, 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 L-type steel beam column.
The technical scheme is that steel part and U-shaped connector that described L-type steel beam column includes that outline is L-type, described
Connector is connected on the steel plate of steel part long limit, and offside U-shaped connector overlaps.Connector along steel part longitudinally with between certain
Away from layout；Described connector is made up of rod iron；Or described connector is made up of deformed bar.Or described connector is by strip
Steel plates etc. are made.
L-type steel beam column includes steel part and the U-shaped connector that outline is L-type, and described connector is in L-type steel part corner two
Side, can form a region in corner, and adjacent both sides, this region are steel plate, and the most adjacent both sides are U-shaped connector.
Described L-type steel beam column includes steel part and the U-shaped connector that outline is L-type, and it is long that described connector is connected to steel part
On the steel plate of limit, offside U-shaped connector overlaps；Described U-shaped connector overlapping regions is inserted into longitudinal reinforcement, with connector
Constitute skeleton, improve the connector drawknot ability to steel plate, facilitate interlayer to connect.
Described L-type steel beam column includes steel part and U-shaped connector, and described connector is connected on the steel plate of steel part long limit, offside U
Shape connector overlaps；Described steel part connected piece is divided into more than one region, has poured concrete and (water in subregion
Template need to be set when building concrete in steel part).Concrete can pour at the scene；Or pour in factory, together with steel beam column
Make prefabricated component；Or the concrete in subregion pours in factory, making prefabricated component together with steel beam column, remainder exists
Pouring at the scene, the concrete that factory pours improves the rigidity of steel beam column long limit steel plate, prevents transport, lifting, cast in situs
Steel plate deformed during concrete, and improve the bearing capacity of steel beam column, it is ensured that working security.
When factory's casting concrete, described U-shaped connector is not cast in concrete, the steel concrete group of formation
After component transports scene, then pour into concrete, the globality of pouring concrete after raising, and convenient in U-shaped connector interpolation
Enter 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, thereon welding U-shaped connector,
Then relatively make U-shaped connector overlap long limit steel plate, form steel part at steel plate two ends, long limit welding steel.
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 L-type steel beam column is steel plate, weldering
Connecing workload big, steel using amount is high；The connectors such as present invention steel pole replace part or all of steel plate dividing plate, reduce welding job amount
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 cannot be welded to connect at interlayer, and clapboard stress is difficult to continuously, and it is long that dividing plate only plays connection, steel part of putting more energy into
The effect of limit 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 leads to
Cross and vertical muscle is set continuously, improve 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) restriction ability to concrete is ensured.Connector connects long limit steel plate, confined concrete together；Appropriate design
Under, connector can be close to steel diaphragm to the binding effect of concrete.
(5) 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 problems such as the making brought is complicated.
(6) 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.
(7) 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.
L-type steel beam column of the present invention can be used for vertical supporting member, also can be used for other structural elements.
