Description
Technical field
The present invention relates to a kind of strong constraint concrete core cylinder that the dark beam of bright post is set, belong to field of civil engineering, be mainly used in construction work.
Background technology
The in recent years develop rapidly of China's economy and society impels highrise building to build in a large number, and its scale constantly enlarges, highly constantly increases, and structural system is also more and more diversified.The concrete core cylinder is widely used in becoming the main body of structure lateral resisting rigidity in all kinds of tall building structures systems because self rigidity is large.Therefore the performance of Core Walls Structure is directly connected to integrally-built performance.For the highrise building that shockproof requirements is arranged, Core Walls Structure then becomes the first line of defence and the key member of providing fortification against earthquakes.Yet common concrete core cylinder Shortcomings on anti-seismic performance, show as, Core Walls Structure bears greatly the most of horizontal earthquake action of structure because of rigidity when, the brittleness of concrete material itself makes its easily very fast failure, cause its horizontal bearing capacity to descend rapidly, deformation performance is poor, thereby affects the quake-resistant safety of Core Walls Structure and even total.For this situation, the present invention intends the concrete core cylinder is arranged the bright post of concrete frame and the secretly measure of beam by employing, forms the strong constraint Core Walls Structure, the horizontal bearing capacity of Effective Raise cylindrical shell, distortion and energy dissipation capacity, particularly improve its later stage performance, in order to antidetonation.
Summary of the invention
The object of the present invention is to provide the good dark beam strong constraint of the bright post concrete core cylinder of a kind of anti-seismic performance.
The present invention adopts following technical scheme:
A kind of strong constraint concrete core cylinder that the dark beam of bright post is set that the present invention proposes, it comprises the dark beam in concrete wall, concrete frame column and the concrete wall; Configuration level distribution reinforcement and vertical distribution reinforcement in the described concrete wall; Concrete frame column is arranged at the concrete wall intersection of the both direction in Core Walls Structure bight, the horizontal section size of concrete frame column along on the thickness direction of adjacent each concrete wall respectively greater than thickness of wall body, formation protrudes from the bright post of rectangle or L shaped cross section of metope, dispose vertical muscle and stirrup in the concrete frame column, the horizontal distribution reinforcing bar in the concrete wall extend into anchoring in the concrete frame column; Inherent each the story height place of concrete wall arranges dark beam, and the width of dark beam is identical with the concrete wall body thickness; Dark beam extends along the horizontal length direction of concrete wall in the longitudinal direction, finally links to each other with the concrete frame column at two ends respectively.Be provided with the body of wall of door and window hole for the floor place, dark depth of beam is got the height of wall hole coupling beam.Dark top surface of the beam and bottom surface dispose elongated vertical muscle and stretch into and carry out anchoring in the frame columns, along described dark beam total length configuration stirrup.Dark beam formation in concrete frame column and the concrete wall and concrete wall are built the space constraint framework into integral body.
The steel column that connects along the cylindrical shell short transverse is set in the described concrete frame column and in the wall hole edge member, the position of the cross section near middle of dark beam arranges the girder steel that connects along the beam length direction in the described concrete wall, adopt between girder steel and the steel column to be rigidly connected, form the Steel Space skeleton of concrete barrel inside.
Described girder steel and steel column adopt rolling section steel member or welded section steel member.
Compare with the ordinary reinforced concrete Core Walls Structure, the present invention has the following advantages:
In normal operational phase, cylindrical shell rigidity is large, is out of shape little; Do the time spent at violent earthquake, because the effect of contraction of the space frame that frame columns and dark beam form reaches the direct reinforcement to the cylindrical shell bight, cylindrical shell Its ultimate bearing capacity and deformability are improved, destroy and postpone, particularly effectively improve its later stage performance, avoid the too early conquassation of cylinder body bottom concrete, make the energy consume mechanism at coupling beam beam-ends plastic hinge and other positions be able to more fully realize.When inner barrel is provided with the Steel Space skeleton that girder steel and steel column form, steel frame can with the concrete acting in conjunction that begins to enter failure stage, make the cylindrical shell self as the system key member form later stage drag system.Therefore, the strong constraint concrete core cylinder that the dark beam of bright post is set that the present invention proposes can be obtained positive effect for the anti-seismic performance aspect that improves the concrete core cylinder, and greatly improves the quake-resistant safety of structural system.
