Description

In-line steel-concrete combined structure component

Technical field

The present invention relates to a kind of in-line steel-concrete combined structure component.

Background technology

Steel concrete combinative structure component has the advantage of xoncrete structure and steel construction, applies more and more extensive in building structure.Shear wall bearing capacity is high, and 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;The ratio on the long and short limit in the cross section of steel-concrete compound shear wall is more than 1, and the binding effect of steel reduces, and generally can pass through to arrange dividing plate and be separated by component, form steel pipe bundle;Owing to dividing plate is difficult to connect at interlayer, its stress performance cannot give full play to.Application number a kind of steel concrete compound shear wall that has been 201410017182.3 patent disclosure, the concrete that the steel pipe bundle of the linearity made by factory and building-site are built in steel pipe bundle forms, being difficult to solder between the dividing plate flaggy of steel pipe bundle, stress performance cannot give full play to;Concrete cast in situs, the amount of building is big, reduces prefabricated rate.

Summary of the invention

The shortcoming big in order to solve existing steel concrete combinative structure component cast-in-place concrete amount, improves stress performance, improves building industrialization level, and the present invention provides a kind of in-line steel concrete combinative structure component.

The technical scheme is that.

A kind of in-line steel concrete combinative structure component, including steel beam column and concrete, described steel beam column includes box-shaped steel part and dividing plate, and box-shaped steel part is divided into more than one cavity by dividing plate, and described concreting is in cavity;Described cavity low portion space not casting concrete forms gap, and gap location box-shaped steel part sidewall reserves grout hole;After described structural elements is installed, box-shaped steel part is connected on (welding or bolt connect) understructure component, in concrete gap, injects grouting material by grout hole.In box-shaped steel part, casting concrete forms steel precast concrete combined member, reduces cast-in-place concrete amount;Cavity low portion region not casting concrete, facilitates box-shaped steel part to be connected with understructure, for instance, concrete will not be damaged to during welding;The reserved grout hole of box-shaped steel part sidewall and venthole, pouring into grouting material in gap, to realize levels concrete continuously.In order to increase the binding ability of concrete and steel beam column, box-shaped steel part is provided with peg.

Described in-line steel concrete combinative structure component, hole or groove on the dividing plate of described gap location.By reserving hole on dividing plate and groove, steel beam column cavity connection, convenient grouting.

Dividing plate lower end or the upper end of described in-line steel concrete combinative structure component arrange angle steel, and angle steel two limb connects (welding or bolt connect) respectively on dividing plate and box-shaped steel part.Angle steel can be hot-rolled angle steel, it is also possible to be the angle steel of Plate Welding composition;Angle steel two limb is connected on dividing plate and box-shaped steel part, it is achieved interlayer clapboard stress is continuous.In prior art, the encased steel plate of steel beam column can be connected with adjacent bed component easily, but dividing plate is difficult to connect;Being connected to by angle steel two limb on dividing plate and box-shaped steel part, the power suffered by dividing plate first passes on angle steel, then passes on box-shaped steel part, or is directly connected to by the angle steel of levels, it is achieved clapboard stress is continuous.

The present invention compared with prior art has the advantage that.

(1) building structure industrialized level is improved.The technology Shi Xian factory of existing making in-line steel concrete member makes the in-line steel beam column with cavity, building-site casting concrete in cavity is arrived in transport, namely the concrete in all cavitys is all built at the scene, and poured in place concrete amount is big, and building prefabrication rate is low.And combined member disclosed by the invention, first factory makes the in-line steel beam column with cavity, then in factory in cavity casting concrete (this operation can also other places beyond erecting bed complete), the component so formed is made up of steel and precast concrete.Visible technical solution of the present invention substantially reduces cast-in-place concrete amount, improves the prefabricated rate of building structure, improves building structure industrialized level.

(2) stress performance of horizontal joint is ensured.Grouting material is arranged at the cavity bottom of the present invention, it is ensured that the concrete seriality of horizontal joint.

(3) ensure that steel diaphragm stress is continuous.In in-line steel concrete combinative structure component, it is continuous that outside plate realizes interlayer by welding, but dividing plate is difficult to connect.Adopt the technology of the present invention, by arranging angle steel, it is achieved steel diaphragm stress is continuous.

(4) stress performance of construction stage assembly unit is improved.Described in-line steel concrete combinative structure component, as vertical applied force component, needs to bear bigger construction loads in the construction stage;Relative to existing technology, in member cavities of the present invention, fill up concrete, significantly improve stress performance, improve construction stage safety.
