Description
Technical field
The present invention relates to a kind of confined concrete Core Walls Structure that the split type coupling beam of level is set, belong to field of civil engineering, be mainly used in construction work.
Background technology
The concrete core cylinder is widely used in all kinds of tall building structures systems because self rigidity is large, becomes main body and the key member of structure lateral resisting rigidity.The performance of Core Walls Structure is directly connected to integrally-built performance.Yet common concrete core cylinder Shortcomings on anti-seismic performance, show as, Core Walls Structure greatly at first bears the most of horizontal earthquake action of structure because of rigidity when, the brittleness of concrete material itself makes again its easily very fast failure, it is very fast to cause its horizontal bearing capacity to descend, deformation performance is poor, thereby affects the quake-resistant safety of Core Walls Structure and even total.On the other hand, when Core Walls Structure has the functions such as elevator shaft concurrently, because door and window hole is arranged, become the Core Walls Structure that punches, body of wall is made of coupling beams between openings and wall limb.When width of cave entrance hour, coupling beam often becomes the little strong coupling beam of span-depth radio, and the shear failure of fragility occurs under horizontal earthquake action easily, can not realize coupling beam bending energy-wasting mechanism, and causes the disconnection that links between the wall limb, and is unfavorable to antidetonation.For above-mentioned situation, the present invention's employing arranges the measure reinforcement of the bright post of concrete frame and dark beam to the constraint of cylindrical shell wall limb, improve its horizontal bearing capacity and deformability, the strong coupling beam that span-depth radio is little replaces with the split type coupling beam of some levels simultaneously, become weak coupling beam, avoid shear failure, guarantee its performance power consumption effect, to improve the anti-seismic performance of the above-mentioned concrete core cylinder that punches.
Summary of the invention
The object of the present invention is to provide the confined concrete Core Walls Structure of the good split type coupling beam of the level that arranges of a kind of anti-seismic performance.
The present invention adopts following technical scheme:
The confined concrete Core Walls Structure of the split type coupling beam of the level that arranges that the present invention proposes, it comprises the dark beam in concrete wall limb, the split type coupling beam of level, concrete frame column and the concrete wall limb.Described concrete wall limb configuration level distribution reinforcement and vertical distribution reinforcement.The split type coupling beam of level is arranged at the top of concrete core cylinder door and window hole, is cast in the concrete wall limb of both sides, hole; The split type coupling beam of described level is comprised of upper straton coupling beam, lower straton coupling beam and the horizontal blanking layer that connects fully between upper and lower straton coupling beam, the deck-siding of upper straton coupling beam and lower straton coupling beam is all identical with thickness of wall body, be furnished with vertical muscle and stirrup, formed by concreting, vertical muscle is anchored in the concrete wall limb.Concrete frame column is arranged at the concrete wall intersection of the both direction in each bight of Core Walls Structure, the horizontal section size of frame columns along on the thickness direction of adjacent each concrete wall respectively greater than wall thickness, formation protrudes from the bright post of rectangle or L shaped cross section of metope, dispose vertical muscle and stirrup in the post, wall limb horizontal distribution reinforcing bar stretches into anchoring in the frame columns; Each story height place arranges dark beam in the concrete wall limb, and the width of dark beam is identical with concrete wall limb thickness; Dark beam extends along the horizontal length direction of wall limb in the longitudinal direction, finally links to each other with the wall hole edge member with frame columns respectively at two ends.The two ends of the vertical muscle of dark top surface of the beam and bottom surface are stretched into respectively in frame columns and wall hole edge member or the split type coupling beam of level and are carried out anchoring, along described dark beam total length configuration stirrup.
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 the dark beam in the described concrete wall limb arranges the girder steel that connects along the beam length direction, adopts between girder steel and the steel column to be rigidly connected.
Described girder steel and steel column adopt rolling section steel member or welded section steel member.
Horizontal blanking layer in the split type coupling beam of described level also can replace with horizontal separation layer, the structural form of horizontal separation layer is: adopt the lightweight low-intensity material, comprise gas concrete, foam concrete or polyphenyl plate, completely be laid between the soffit of the upper surface of lower straton coupling beam and upper straton coupling beam, upper straton coupling beam, lower straton coupling beam are separated.
Compare with the ordinary reinforced concrete Core Walls Structure, the present invention has the following advantages:
Do the time spent at violent earthquake, because frame columns and dark beam can improve Its ultimate bearing capacity and the deformability of wall limb, and avoid the concrete too early conquassation of cylinder body bottom to the effect of contraction of wall limb and to the direct reinforcement in cylindrical shell bight; And the setting of the split type coupling beam of level has replaced the little strong coupling beam of span-depth radio, can effectively improve the stress performance of coupling beam, makes cylindrical shell satisfy the designing requirement of " strong shear capacity and weak bending capacity, the weak beam of strong wall "; Its structure is comparatively simple simultaneously, convenient construction.Therefore, the confined concrete Core Walls Structure of the split type coupling beam of the level that arranges that proposes of the present invention be one be conducive to improve punch concrete barrel anti-seismic performance and be convenient to the technology that engineering is used.
