Description
Technical field:
The utility model relates to a kind of building, bridge and other of being used for needs energy-dissipating and shock-absorbing to support small eight character type curved stick style framework under the occasion, particularly a kind of bracing frame that has the crank throw support structure of damper effect.
Technical background:
The energy-dissipating and shock-absorbing technology is usually at some position of the works of occasions such as building, locate to be provided with the energy dissipating that viscoelastic damper or fluid damper are installed as support, beam bolt node, truss lower chord etc. and support, the seismic energy of the hysteresis distortion dissipation input structure that supports by this energy dissipating is realized shock-absorbing function.It is several that the energy dissipating supporting form of using always in many building frames mainly contains little Eight characters support, unidirectional diagonal brace, chevron shaped support etc. at present, and its medium and small Eight characters support and the support of unidirectional crank throw are more common in using recently.Little Eight characters energy dissipating support is arranged on the top of framework, is splay configuration, although be the effective utilization that relatively helps structure space, facts have proved that its axial deformation is little, the energy dissipating limited ability; And unidirectional crank throw energy dissipating support is provided with the crank throw support of band damper at its frame construction diagonal angle, the stratified deformation of energy structure for amplifying, desirable energy dissipating effect is arranged, but because it has taken the major part space of total, bigger to the building function effect, the layout utilization in space in the building framework is restricted, so the shortcoming on some structures of ubiquity and the performance is supported in the energy dissipating of existing building frame.
The shortcoming that the utility model exists according to above-mentioned prior art, be intended to seek to design the various support advantages of a kind of absorption, accumulate a kind of structural principle and simply have the frame support structure of the small eight character type curved stick style of good energy-dissipating and shock-absorbing effect, particularly a kind of support that is provided with viscoelastic damper or fluid damper, and can adjust indexs such as bearing height and angle by the difference requirement, increase result of use.
Technology contents:
For the purpose that realizes that foregoing invention is created, the employed crank throw support of the utility model is arranged on the top of supported framework, being the splay configuration symmetry by two same structures installs, wherein every small eight character type crank throw support is made up of three sub-support interconnections, be shaped on damper in the middle of one sub-support, the top is connected with end of frame girder by bolt, the lower end connects into the concentric structure with the end points that intersects of two sub-supports and three sub-supports respectively, the upper end of two sub-supports is connected with Vierendeel girder middle part one side, the lower end of three sub-supports is connected with the frame column middle part, and each tie point is fixed connection; Angle between the vertical line of two sub-support center lines and Vierendeel girder is 30 °~55 °, the center line of three sub-supports and the level of Vierendeel girder between angle be 15 °~40 °, the center line of one sub-support and three sub-supports is orthogonal, and this can make the crank throw support maximum in the axial amplification of damper to the lateral deformation of frame construction; Three employed material stiffnesses of sub-support can effectively be brought into play the energy-dissipating and shock-absorbing effect of damper greater than 3~6 times of damper shearing rigidities.This small eight character type crank throw support structure also can be used for the building of body of wall floor slab structure, to realize the energy-dissipating and shock-absorbing effect.
The utility model is compared with the support technology of available frame formula building, flexibility is more controlled in its damping design, and good energy dissipating ability is arranged, using under the damper situation of the same race, can improve damping effect, reduce integrally-built cost, be specially adapted to the frame supported under the big occasion of supporting power, and desirable shock-damping energy-dissipating effect is arranged.
Description of drawings:
Fig. 1 is a structural principle schematic diagram of the present utility model, owing to be symmetrical structure, only the list to the crank throw support props up label declaration.
Specific embodiments:
Enforcement of the present utility model mainly contains Vierendeel girder 1, frame column 2, set bolt 3,6,9,10 and 25, steel plate 4,11 and 24, supporting steel plate 5,8,12,17,18 and 23, damper 7, connect steel plate 14,16,19 and 21, angle steel supports 15 and 20, and two sub-supports combine the symmetrical fully installation of its another crank throw support to angle 22 with level with Vierendeel girder vertical line angle 13 and three sub-supports.Wherein being connected of each bolt is the formula that rigidly fixes and connects guaranteeing the firm of general frame, when docking without bolt between each steel plate, all adopts welding, and its damper selects for use the viscoelastic damper of commercially available routine or fluid damper all can; The support of every crank throw is made up of three sub-supports, and its three end points are fixed on the same axial line by bolt 9 and form the crank throw structure; It is a sub-support that steel plate 4, supporting steel plate 5, bolt 6, damper 7, supporting steel plate 8 constitute one, and its middle part is shaped on damper 7; Steel plate 11, supporting steel plate 12, connection steel plate 14, angle steel support 15, connection steel plate 16, supporting steel plate 17 constitute two sub-supports, and the vertical line of its center line and Vierendeel girder 1 (or vertical line) angle 13 is 30 °~55 °; Supporting steel plate 18, connection steel plate 19, angle steel support 20, connection steel plate 21, supporting steel plate 23 and steel plate 24 constitute three sub-supports, and its center line and level are 15 °~40 ° to angle; Can adjust the occurrence of angle 13 and 22 in the framework of same building thing according to the energy dissipating ability, the vertical line angle of a sub-support and Vierendeel girder can be determined simultaneously.
1: one of embodiment is used for the framework that petrol filling station's ceiling supports, form by two the utility model frame constructions, top cover weight is 10 tons, it is the straight steel column of I shape that its Vierendeel girder 1 and frame column 2 are all elected the cross section as, select viscoelastic damper for use, two sub-supports and Vierendeel girder vertical line angle in its crank throw support are 43 °, and three sub-supports and level are 31 ° to angle; Record this frame construction performance and reach the shock-damping energy-dissipating index request fully.
