Abstract
The utility model relates to a steel truss steel skeleton concrete beam, a steel truss steel skeleton is composed of a vertical rod, an edge rod and a slant rod, wherein the vertical rod and the edge rod are combined into a rectangular structure, and the slant rod is obliquely welded between an upper edge rod, a lower edge rod and the vertical rod. The height of a steel truss can be adjusted according to the height of the beam cross section through adopting the steel truss steel skeleton concrete beam. A T-shaped section steel or a slot-shaped section steel can be installed on the upper edge and the lower edge of the beam, and the section steel strength can be fully played. The cementing power performance of the steel truss steel skeleton concrete beam and the concrete is effectively improved. The load of the construction phase can be loaded through using the steel truss, a template is hung on the steel truss, a support is saved, and the construction cost is saved.
Description
One, technical field
The utility model relates to construction work, bridge engineering girder construction, specifically a kind of steel truss steel framed concrete beam.
Two, background technology
Steel reinforced concrete structure (Steel Reinforced Concrete Structure) is called for short the SRC structure, is a kind of new model of steel and concrete combined structure, promptly disposes the combined structure system of shaped steel at ordinary reinforced concrete structure.It is skeleton with the steel work, and the encased steel reinforced concrete, makes the inside reinforcing bar of SRC member and external wrapping concrete form integral body, stressed jointly, and its stress performance is better than the simple superposition of reinforcing bar and two kinds of structures of steel concrete.Steel reinforced concrete structure has intensity height, big and good ductility and the energy-dissipating property of rigidity, and the structure of being made up of the steel reinforced concrete member has good seismic resistance.
Compare with steel work, the encased steel reinforced concrete part of steel reinforced concrete member can effectively prevent the cripling of reinforcing bar member, and can improve the integral rigidity of durability of structures, refractoriness and steel member, significantly improve reinforcing bar plane torsion flexural property, the intensity of steel is given full play to, and had bigger rigidity and damping than pure steel structure.Adopt the general comparable pure steel structure of steel reinforced concrete structure to save steel more than 50%, in addition, concrete is best topping to reinforcing bar, no matter be that fire prevention, anticorrosion and antirust aspect are all obvious superior than steel work.
Present steel framed concrete beam, reinforcing bar is mainly joined real abdomen formula shaped steel, based on I-shaped shaped steel.Real abdomen formula shaped steel steel reinforced concrete structure also comes with some shortcomings except that the above advantage, and mainly contain: 1) owing to the restriction of the I-shaped shaped steel height of real abdomen formula, incompatibility is used for the higher longspan structure in cross section; 2) real abdomen formula shaped steel intensity is not fully utilized; 3) real abdomen formula shaped steel is compared with ordinary reinforced concrete structure with concrete binding power performance certain weakening; 4) real abdomen formula shaped steel is symmetrical section, is unfavorable for reducing the shaped steel steel using amount at pressure zone, gives full play to concrete resistance to compression effect.
Three, summary of the invention
The purpose of this utility model provides a kind of longspan structure that is applicable to that the cross section is higher, can not be subjected to the steel truss steel framed concrete beam of I-shaped shaped steel height restriction according to beam section Height Adjustment steel truss height.
The utility model achieves the above object with following technical proposals: a kind of steel truss steel framed concrete beam is provided, and its steel truss reinforcing bar is to be made of montant, edge bar, brace.Wherein, montant and edge bar are formed rectangular configuration, and brace is oblique to be welded between upper limb bar, lower edge bar and the montant, stirrup and construct longitudinal reinforcement and to join real abdomen formula shaped steel steel framed concrete beam identical.
Described steel truss steel framed concrete beam can be made square-section or T section beam.
Shaped steel in the described steel truss reinforcing bar can be tee bar, angle steel, channel-section steel.
Outstanding advantage of the present utility model is:
1, adopts the steel truss steel framed concrete beam, tee bar or flute profile shaped steel are configured in the last lower edge of beam, can not be subjected to I-shaped shaped steel height restriction, give full play to shaped steel intensity according to beam section Height Adjustment steel truss height.
2, effectively improve steel truss steel framed concrete beam and concrete binding power performance.
3, can be according to structure needs appropriate design pressure zone shaped steel steel using amount.
4, because steel truss itself has certain bearing capacity, can utilize steel truss to bear the load of construction stage, and template is suspended on the steel truss, save support, save construction cost, be a kind of technological innovation to the bridge construction that is not easy to establish support.
