Further, in the preferred embodiment shown in Fig. 1, by being symmetrical arranged up and down along the center line on metal shears cut type damper short transverse (Z-direction) between the first constraint component 61 and the second constraint component 62.
Side constraint parts 6 and 6 ' and first the edge of a wing 4 and the second interval, the edge of a wing 5 arrange.Preferably, the spacing of side constraint parts 6 and 6 ' and first between the edge of a wing 4 is 10 ~ 30mm; The spacing of side constraint parts 6 and 6 ' and second between the edge of a wing 5 is 10 ~ 30mm.As shown in Figure 1, side constraint parts 6 with the first constraint component 61 and the second constraint component 62 be not all connected with first edge of a wing 4 and second edge of a wing 5.Because side constraint parts 6 include the first constraint component 61 and the second constraint component 62 two parts, first constraint component 61 is connected with the first junction plate 1, second constraint component 62 is connected with the second junction plate 2, and the first constraint component 61 and the second constraint component 62 are not connected with first edge of a wing 4 and second edge of a wing 5, therefore, can avoid occurring as metal shears cut type damper of the prior art needs in situation central layer being offered too much circular hole or slotted hole that consumes energy, reduce the adverse effect that the performance of perforate to metal shears cut type damper causes, improve metal shears cut type damper performance and stability.
Power consumption central layer 3 opposite flank constraint component 6 and 6 ' can carry out laterally (along X-direction) yield displacement.Specifically, in metal shears cut type damper of the present utility model use procedure, when building structure is because of reasons such as earthquakes, when producing relative storey displacement, the two ends up and down of power consumption central layer 3 vertical direction (along Z-direction) will produce yield displacement along its width (along X-direction), be understandable that, because the first junction plate 1 is connected with building structure with the second junction plate 2, therefore, the central layer 3 that consumes energy is larger the closer to the part yield displacement at upper and lower two ends.In order to side constraint parts 6 and 6 ' do not participate in the tension loading process of the transverse direction of metal shears cut type damper, make its stress form and act on clearer and more definite, avoid its pulling force because of metal shears cut type damper transverse direction and premature failure, therefore, in metal shears cut type damper of the present utility model, side constraint parts 6 and 6 ' and first the edge of a wing 4 and the second interval, the edge of a wing 5 arrange, and make to adopt the mode relatively can carrying out laterally (along X-direction) yield displacement to connect between power consumption central layer 3 and side constraint parts 6 and 6 '.
Refer to Fig. 1 and Fig. 2, be positioned between the first constraint component 61 of both sides before and after power consumption central layer 3 and the first constraint component 61 ' and power consumption central layer 3 by a high-strength bolt 7 (referring to Fig. 2).First constraint component 61, first constraint component 61 ' and power consumption central layer 3 connect through the first base plate 611 of the first constraint component 61, the first base plate 611 ' of consume energy central layer 3 and the first constraint component 61 ' by high-strength bolt 7 successively.And consume energy on the center line of central layer 3 short transverse (along Z-direction) because high-strength bolt 7 is not arranged at, therefore, can there is yield displacement because of relative storey displacement in the position that on power consumption central layer 3, high-strength bolt 7 is arranged.Laterally (along X-direction) yield displacement can be carried out relative to the first constraint component 61 and 61 ' to make power consumption central layer 3, as shown in Figure 1, the link position of the high-strength bolt 7 in the first constraint component 61 and 61 ' offers the slotted hole 64 of a horizontally set, and (slotted hole 64 is greater than its height along Z-direction along the width of X-direction, can see Fig. 1), as shown in Figure 1, the link position of the high-strength bolt 7 in the first constraint component 61 and 61 ' is the first base plate 611 and 611 ' and the link position of high-strength bolt 7, the connection between power consumption central layer 3 and the first constraint component 61 and 61 ' is made to be the connection that yield displacement can be carried out in local with this.The link position of the high-strength bolt 7 on power consumption central layer 3 also can offer a circular hole (not shown).In addition, because the position yield displacement the closer to power consumption central layer 3 center is less, the width (along X-direction) that slotted hole 64 is offered can be reduced, reduce the impact that performance and the stability of power consumption central layer 3 are produced, therefore, preferably, slotted hole 64 is arranged at the position at the center closer to power consumption central layer 3.
Similarly, be positioned between the second constraint component 62 of both sides before and after power consumption central layer 3 and the second constraint component 62 ' and power consumption central layer 3 by another high-strength bolt 7.Second constraint component 62, second constraint component 62 ' and power consumption central layer 3 connect through the second base plate 621 of the second constraint component 62, the second base plate 621 ' of consume energy central layer 3 and the second constraint component 62 ' by high-strength bolt 7 successively.The link position of the high-strength bolt 7 in the second constraint component 62 and 62 ' also offers the slotted hole 64 of a horizontally set.To serve the same role, do not repeat them here.
Metal shears cut type damper of the present utility model is by using a high-strength bolt 7 to be connected respectively with two the second constraint component 62,62 ' two of the correspondence of both sides before and after it the first constraint component 61,61 ', effectively can improve the bending rigidity of side constraint parts 6 and 6 ', and play the effect of abundant clamping side constraint component 6 and 6 '.
Further, for the ease of power consumption central layer 3 relative to side constraint parts 6 and 6 ' horizontal yield displacement, metal shears cut type damper also comprises non-cohesive material 8.As shown in Figures 2 and 3, non-cohesive material 8 is arranged at side constraint parts 6 and between 6 ' and power consumption central layer 3.The friction factor of non-cohesive material 8 is less, and friction factor is preferably 0.01 ~ 0.1.Non-cohesive material 8 can be made up of materials such as high strength non-shrinkage concrete or high strength ungauged regions composite mortars.Non-cohesive material 8 is attached at the surface of power consumption central layer 3 by gluing mode.
In sum, in conjunction with the embodiment shown in above-mentioned Fig. 1 to Fig. 3, those skilled in the art understand, metal shears cut type damper of the present utility model is by being divided into two side constraint parts, and side constraint parts are connected with adjacent junction plate, and be not connected with two side wing edges, can avoid offering too much hole on power consumption central layer, thus reduce perforate to the adverse effect of damper performance, improve metal shears cut type damper performance and stability; By perforate use high-strength bolt to be connected respectively with two the second constraint component two of the correspondence of its both sides the first constraint component in the middle part of power consumption central layer, effectively can improve the bending rigidity of side constraint parts, and play the effect of fully clamping both sides side constraint parts.
Although the utility model with preferred embodiment disclose as above, but itself and be not used to limit the utility model.The utility model person of ordinary skill in the field, not departing from spirit and scope of the present utility model, when doing various changes and amendment.Therefore, the scope that protection domain of the present utility model ought define depending on claims is as the criterion.
