Description
Technical field
The present invention relates to a kind of reinforced concrete frame structure, particularly a kind of frame structure of floor slab locally provided with seams.
Background technology
《Seismic design provision in building code》(GB 50011-2010) be to reinforced concrete frame structure by " strong column and weak beam,
Strong shear capacity and weak bending capacity, strong node anchor by force weak component ", to ensure that structure has preferable ductility, make structure reach " no damage in small earthquake, in
Shake can repair, no collapsing with strong earthquake " shockproof requirements.Current frame structure employs the increase of styletable moment of flexure to realize " strong column and weak beam "
Coefficient, in order to realize that " strong shear capacity and weak bending capacity " employs shearing enhancement coefficient, so that frame structure plastic hinge under big shake effect occurs
In framework beam-ends, form beam hinge surrender mechanism, but many earthquakes especially Chinese Wenchuan earthquake shows, many frame structures although
Aseismic Design is carried out according to mentioned above principle, still there is more styletable to occur in that plastic hinge, form the failure mechanism of " the weak post of brutal ",
Many frame structures even collapse therefrom, more the reason for there is this phenomenon, but wherein more important are a bit：Frame
Setting a roof beam in place the work that muscle take part in framework beam-ends of indulge in the cast-in-situ floor and floor of side, the actual bending resistance for increasing framework beam-ends is carried
Power, makes the actual anti-bending bearing capacity of framework beam-ends higher than framework styletable, and forms the structural system of " the weak post of brutal ", and making should
Vierendeel girder end occur plastic hinge be transferred in frame column, or even form post hinge surrender mechanism and recurring structure integrally falls
Collapse.It can be seen that, contribution of the cast-in-situ floor to framework beam-ends anti-bending bearing capacity is eliminated, frame structure is formed beam hinge surrender mechanism
One important measures.
In existing disclosed patent document, application number 2010101640030 is entitled《Reinforced concrete frame node》's
Chinese invention patent application, discloses a kind of reinforced concrete frame node structure, and the structure is in reinforced column and steel
Concrete floor around the intersection point of Concrete Beam Reinforced is provided with angle of release seam, and the knot of strong column and weak beam is realized to a certain extent
Structure, but it is still present following shortcoming：Can be seen that its angle seam opened from the patent specification accompanying drawing is triangle, root
Understand that to obtain the effect of strong column and weak beam, the preferred range of angle seam length is 500 mm or 1.5h according to the knowledge of this areabOr
2hb, hbIt is framework deck-molding.The area minimum of so this triangle angle seam needs 0.125m2, could realize that preferably strong post is weak
The effect of beam, equivalent to upstairs with downstairs between form a larger logical hole, this structure wastes the usable floor area of house,
Connected upstairs with use space downstairs, resident family be unsatisfied with, construction unit is also unsatisfied with, therefore is in practice infeasible
's.Many elevation of building requirements set door and window near post side, and post side floor sets cavity, will can not meet building to door and window
Setting needs, therefore considers also infeasible from elevation of building.
The content of the invention
The technical problem to be solved in the present invention is：The antidetonation that providing one kind can both meet " strong column and weak beam, strong shear capacity and weak bending capacity " is wanted
Ask, improve the frame structure of steel frame ductility and the floor slab locally provided with seams of power consumption, and do not change the use requirement of current building, and gram
Take the above-mentioned part of Shortcomings in the prior art.
Solving the technical scheme of above-mentioned technical problem is：A kind of framework of floor slab locally provided with seams, including frame column, Vierendeel girder
And floor, the described end of frame girder both sides with frame column junction are provided through the straight joint of slab thickness, and described is logical
Seam includes connecting with longitudinal L-shaped straight joint of frame column junction floor and through transverse frame beam and frame column through longitudinal framing beam
The transversally L-shaped straight joint of place's floor is connect, longitudinal L-shaped straight joint and transversally L-shaped straight joint are mutually communicated, the described floor model for being provided with straight joint
The vertical muscle for enclosing is unpack format with framework beam-ends.
The generous D of described straight joint is 0.5-2mm.
The length L that described longitudinal L-shaped straight joint and transversally L-shaped straight joint are located at Vierendeel girder side is 500 mm or 1.5hbOr 2hb,
hbIt is framework deck-molding.
Described being provided between the two frame girders of straight joint is provided with small secondary beam, and described small secondary beam is connected to floor and leads to
On Vierendeel girder outside seam scope.
Because the framework for using said structure, the floor slab locally provided with seams of the present invention has the advantages that：
The present invention sets the straight joint through thickness of slab, and set seam model in the both sides floor of each framework beam-ends plastic hinge scope
Enclose the vertical muscle of floor not anchor into Vierendeel girder, and separated with framework beam-ends, so as to eliminate framework beam-ends both sides floor to Vierendeel girder
The contribution of anti-bending bearing capacity is held, framework plastic hinge is appeared in beam-ends, form beam hinge surrender mechanism, realize " strong column and weak beam, cutting by force
It is weak curved " design requirement, improve Seismic Behavior of Frame Structure.Floor sets seam in framework beam-ends, is set outside seam scope in floor, can set
Put small secondary beam and be used to encorbelment and set seam scope floor, setting seam scope floor to this by the requirement arrangement of reinforcement of cantilever slab, and can meet corresponding
Rigidity requirement.
Because floor sets seam in framework beam-ends, and vertical muscle of floor is not anchored into Vierendeel girder at this, thus framework beam-ends two
The floor of side and its vertical muscle are not involved in the work of framework beam-ends, eliminate framework beam-ends floor and its vertical muscle to framework beam-ends bending resistance
The contribution of bearing capacity, so as to the shockproof requirements of " strong column and weak beam, strong shear capacity and weak bending capacity " can be realized, improves steel frame ductility with power consumption.It can be seen that,
Floor slab locally provided with seams framework of the present invention can improve the shock resistance of structure.
Reality work progress of the invention is simple, is not take up usable floor area, and the normal of space is used under upstairs house is not influenceed.Applying
During work, it is possible to use certain thin material such as fireproof felt is attached to Vierendeel girder both sides, then placing concrete forms floor, you can
Form the structure of the framework of the floor slab locally provided with seams of the present invention.Straight joint of the invention is L-shaped or inverted L-shaped, thickness 0.5-2mm, length
Degree L is 500 mm or 1.5hbOr 2hb, hbIt is framework deck-molding, can be achieved with preferable strong column and weak beam effect, the maximum area of straight joint
It is only 0.0032m2, its take usable floor area almost can be ignored.User can also simply use in finishing
After some acoustic materials block straight joint, it is possible to fitted up according to its needs, this straight joint does not interfere with space under upstairs house
Normally use.Therefore the present invention has advantage applied widely, practical.
Below, the technical characteristic in conjunction with the accompanying drawings and embodiments to the framework of the floor slab locally provided with seams of the present invention makees further
Explanation.
