Abstract
本发明公开了一种内置空间桁架钢骨的混凝土梁，其空间桁架钢骨是由纵向两排或者两排以上的平面桁架以及加设在它们之间的横向连接件组成的整体。纵向的平面桁架是由上下缘杆、竖杆、斜杆组成，横向连接件是由横杆、斜杆组成。在这种混凝土梁中，空间桁架钢骨与混凝土形成整体而共同承担荷载，其受力性能优于空间桁架钢骨和混凝土梁两种结构的简单叠加。由于该空间桁架钢骨可以单独受力，因此还可以用其承担施工时的荷载。
The invention discloses a concrete beam with a built-in space truss steel frame. The space truss steel frame is a whole composed of two or more rows of plane trusses in the longitudinal direction and transverse connecting pieces added between them. The longitudinal planar truss is composed of upper and lower edge bars, vertical bars, and oblique bars, and the horizontal connector is composed of horizontal bars and oblique bars. In this kind of concrete beam, the space truss steel frame and the concrete form a whole to bear the load together, and its mechanical performance is better than the simple superposition of the two structures of the space truss steel frame and the concrete beam. Since the steel frame of the space truss can bear force alone, it can also be used to bear the load during construction.
Description
Technical field
The present invention relates to the concrete beam of a kind of beam, particularly a kind of built-in space truss steel skeleton.
Background technology
Traditional reinforced concrete beam mainly is to bear the pulling force concrete by reinforcing bar to bear pressure and bear load jointly, but behind concrete cracking, the cross section reduces, and the stress performance in cross section obviously changes, and is very big to the influence of structure.If the reinforcing bar of concrete beam the inside can be own to a structure, even concrete cracking is just smaller to the whole stressed influence of reinforced concrete beam.Steel reinforced concrete is exactly an example.
Steel reinforced concrete structure is called for short the SRC structure, is a kind of new situations of firm 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 external wrapping 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.
Summary of the invention
The object of the present invention is to provide a kind of concrete beam of novel, built-in space truss steel skeleton with good stress performance.
The objective of the invention is to be achieved through the following technical solutions: at first by vertical edge bar, montant and brace constitute plane frame, wherein form rectangular configuration by montant and last lower edge bar, and brace adds on the diagonal that is located at rectangular configuration, forms stable triangle; The brace of horizontal cross bar and intersection is set between plane frame again, adding the transverse connection that is located between the plane frame should be every a determining deviation setting, and be located on the node of montant, make it two or more plane frame is connected, form the overall space truss; Last fluid concrete has just constituted the steel framed concrete beam of this kind built-in space truss.Rod member in the built-in Steel Space Truss steel reinforced concrete can be a plain bars, angle steel, channel-section steel.
The built-in space truss steel skeleton concrete beam has following advantage:
1. space truss is set in beam, space truss and concrete co-operation, its bearing capacity is much larger than the simple superposition of space truss and bearing capacity of concrete-filled.
2. because built-in space truss, changed the force-bearing situation of beam, stressed bending resistance, shearing resistance by common beam be main change into bending resistance is arranged, shearing resistance, the cooperative complex of resistance to compression, improved the integral rigidity of beam and the coordination ability of distortion, help structural seismic.
3. owing to can be used as an independent structure, can bear load in construction, save support, save cost with it at beam volume inside truss itself.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described:
With reference to Fig. 1～Fig. 3, the concrete beam of built-in space truss steel skeleton of the present invention, its Steel Space Truss reinforcing bar is made up of upper limb bar 1, lower edge bar 2, montant 3, vertical brace 4, horizontal brace 5, horizontal cross bar 6.Wherein form rectangular configuration, vertical brace 4 is added be located between edge bar and the montant again, make rectangle become stable triangle, just constituted the plane frame in the space truss of the present invention by upper limb bar 1, lower edge bar 2, montant 3.Between two plane frames, transverse connection is set again, comprise horizontal cross bar 6 and the brace 5 that intersects, transverse connection should be every a determining deviation setting, and it connects into an overall structure with two plane frames, i.e. the space truss of this kind built-in space truss steel skeleton concrete beam.Last fluid concrete 7 has just formed the concrete beam of this kind built-in space truss steel skeleton.
