Abstract

The utility model relates to a shaped steel concrete combination flat beam, shaped steel concrete combination flat beam includes I -steel, prestressed concrete cored slab, cant chisei, anchor screw rod and the cast -in -place board of concrete, and the welding has the cant chisei on the top flange, and the lower skin weld of top flange has the shear connector, and the welding has the anchor screw rod on the lower flange, and the prestressed concrete cored slab is placed on the lower flange of I -steel, during the anchor screw rod inserted the hole below the prestressed concrete cored slab, the welding had the reinforcing bar net on the top flange of I -steel, and the upper surface of prestressed concrete cored slab is the mat surface. The utility model discloses a shaped steel concrete combination flat beam can effectively improve the wholeness ability, strengthens the adhesion strength of prestressed concrete cored slab and the cast -in -place board of concrete, improves the bearing capacity.

Description

A kind of steel reinforced concrete composite flat beam
Technical field
The utility model relates to a kind of composite flat beam, particularly relates to a kind of steel reinforced concrete composite flat beam.
Background technology
In recent years, in existing building technology, composite flat beam is more and more extensive in the application of some countries as a kind of house demolition, as a kind of novel composite floor system form, girder steel is embedded in concrete floor by steel-concrete composite flat beam, utilizes the co-operation of both the adhesion stress realizations between girder steel and concrete.Adopt the house demolition of steel-concrete composite flat beam, can effectively increase building headroom on the one hand, not have secondary beam to occur in superstructure, reach the effect being similar to " arch without beam ".Meanwhile, steel-concrete composite slim floor has good mechanical property, can carry the imposed load of flooring.
Summary of the invention
In order to improve bearing capacity and the overall performance of steel-concrete composite flat beam in prior art, the utility model provides a kind of steel reinforced concrete composite flat beam.
The technical solution of the utility model is: a kind of steel reinforced concrete composite flat beam, described steel reinforced concrete composite flat beam comprises i iron, prefabricated concrete hollow slab, peg, anchorage screw and concrete cast-in-place slab, the width of the top flange of i iron is 20-30 centimetre, the width of bottom flange is 40-60 centimetre, the upper surface of top flange is welded with peg, the soffit of top flange is welded with shear connector, described shear connector tilts to the web of i iron, the soffit of shear connector and top flange is miter angle, bottom flange upper surface is welded with anchorage screw, prefabricated concrete hollow slab is placed on the bottom flange of i iron, prefabricated concrete hollow slab end contacts with the web of i iron, described anchorage screw inserts in the hole below prefabricated concrete hollow slab, prefabricated concrete hollow slab top is concrete cast-in-place slab, the top flange of i iron is welded with steel mesh reinforcement, described steel mesh reinforcement and peg are cast in concrete cast-in-place slab, the end of prefabricated concrete hollow slab is step-like, end thickness is less than the thickness of prefabricated concrete hollow slab, the upper surface of prefabricated concrete hollow slab is matsurface.
The beneficial effects of the utility model: top flange is welded with peg and steel mesh reinforcement, effectively can strengthen the adhesion strength of i iron and concrete cast-in-place slab, improve the overall performance of steel reinforced concrete composite flat beam, the end of prefabricated concrete hollow slab is stepped, convenient construction, upper surface is matsurface, can strengthen the adhesion strength of prefabricated concrete hollow slab and concrete cast-in-place slab, improves the overall performance of steel reinforced concrete composite flat beam.During construction, prefabricated concrete hollow slab can use as the template of top concrete cast-in-place slab, greatly simplifies construction, reduces construction cost.The soffit of top flange is welded with shear connector, and described shear connector tilts to the web of i iron, and the soffit of shear connector and top flange is miter angle, and make the globality of i iron and concrete cast-in-place slab better, adhesion strength is higher.Bottom flange upper surface is welded with anchorage screw, described anchorage screw inserts in the hole below prefabricated concrete hollow slab, effectively can fix prefabricated concrete hollow slab, avoid in work progress, because mechanical shock or people make prefabricated concrete hollow slab displacement for trampling, affect construction quality.The end of prefabricated concrete hollow slab is step-like, end thickness is less than the thickness of prefabricated concrete hollow slab, like this, the concrete cast-in-place slab of rear cast is in the formation expansion section, position near web, concrete cast-in-place slab after the solidifying end step-like with prefabricated concrete hollow slab is engaged mutually, the bearing capacity of the flat beam of enhanced type steel Combined concrete and overall performance.
