The another kind of structure of a kind of double-deck flap steel plate shear force wall structure of the utility model; Frame column 1 connects and composes square framework with Vierendeel girder 2; The interior fill plate 3 that is connected with Vierendeel girder 2 with frame column 1 is arranged in the framework; Frame column 1 comprises the first parallel frame column 11 and second frame column 12, and interior fill plate 3 is made up of identical first flap 31 and second flap 32, and first flap 31 is connected to form by first protruding 311 and first groove 312 of space; Second flap 32 is connected to form by second protruding 321 and second groove 322 of space; It is characterized in that first protruding 311 equates and be 30 °~60 ° to angle with the post of the length direction of first groove 312 and first frame column 11, the post of second convexity, 321 and second groove 322 and second frame column 12 equates and is 30 °~60 ° to angle; The groove one side of first flap 31 is touched with the groove one side of second flap 32 mutually, and first groove 312 is connected through connector 6 with second groove 322.
A kind of situation of best results, first protruding 311 length direction equates to angle with the post of second frame column 12 to angle and second protruding 321 with the post of first frame column 11.
For making processing technology simpler; Process velocity is more quick; Can directly use the standard plate of shaping, said first flap 31 and second flap 32 use profiled sheet, can be to be V-arrangement, waveform, rib shape, the type of putting more energy into, hyperbolic waveform, dove-tail or the two-way type of putting more energy into; First protruding 311 and second protruding 321 is the crest of profiled sheet, and first groove 312 and second groove 322 are the trough of profiled sheet.
Described connector 6 is rivet or bolt.
Adopt the full-shape weld seam that Vierendeel girder 2 is connected with interior fill plate 3,, adopt fillet weld to add bolt 4 Vierendeel girder 2 is connected with interior fill plate 3 perhaps by means of angle steel 5; Adopt the full-shape weld seam that frame column 1 is connected with interior fill plate 3,, adopt fillet weld to add bolt 4 frame column 1 is connected with interior fill plate 3 perhaps by means of angle steel 5.
The width of said first protruding 311, first groove 312, second protruding 321 and second groove 322 equates, is convenient to processing this moment more.
The thickness of slab of said first flap 31 and second flap 32 is even, and scope is 2mm~12mm, and first groove 312 is 90 ° or acute angles arbitrarily with first protruding 311 the gradient that is connected, and preferably 30 °~60 °, especially effect is preferable 60 ° the time.
The novel theoretical foundation of this novel practical is: the domestic and international research data shows; Have the thin steel plate shear wall flexing of firm constraint can also continue bearing load later all around, main cause is, during the steel sheet flexing; Stress on the steel plate is far from reaching YIELD STRENGTH; In the steel plate plane, formed the pull strap that distributes along diagonal, rely on this pull strap to stand out against horizontal loading.And existing scholar simplifies the pull bar model that steel plate shear force wall, and the pull bar of fill plate all is tilting inner at framework along diagonal in these simulations.The utility model just is based on these theories; Profiled sheet is bidirectionally obliquely placed inner at framework along diagonal; It is vertically distributed along pull strap, so just can make profiled sheet be in a kind of favourable state of tension that receives, not only improved bearing capacity; Can also agents enhance overall stability, the outer unstability of the face that prevents.And can practice thrift steel, reduce cost, have good development prospect.
The beneficial effect of the utility model is:
It is tilting inner at framework along the framework diagonal to tamp shaped steel plate in this new steel plate shear wall; Make the vertically stressed of profiled sheet along the pull strap direction; Reduced the influence of shearing; Make profiled sheet basically near tension state, can give full play to the good advantage of steel tensile property, practiced thrift steel.And strengthened the lateral rigidity of structure, interior fill plate also is not easy to occur destabilization problems under pulling force.In addition, the direction of horizontal forces such as geological process and wind load has randomness, and therefore, the utility model is tilting inner at framework with the profiled sheet way and double-layer, has guaranteed that frame shear wall structure is reverse when stressed, also has same stress performance.
Compared with prior art; The destruction of fill plate only causes because the strength of materials is not enough in the double-deck flap steel plate shear force wall structure of the utility model; And occur in the part, the utility model seismic energy that can also well dissipate is under the general moderate shock effect; Destruction to member is less, has reduced shake back repair amount.Satisfy " middle shake can be repaiied " of antidetonation three stage design; Be equivalent to strengthen lateral rigidity; Interior fill plate is difficult for unstability, and having improved all the time, the thin steel plate shear wall flexing has not only satisfied the requirement of normal use prior to the defective of material yield; But also given full play to the intensity and the ductility of material, practiced thrift steel.In addition,, greatly improved the ability of dissipation seismic energy, also can reduce to shake back repair amount owing to had good ductility.All members of this utility model can be in factory process, the assembling in the building site then, and construction technology is simple, and is cheap, easy to utilize.
