Abstract
The utility model relates to a shear-type lead damper, and belongs to the field of shock absorbing control of building structures. Cover plates (1) are clamped on the upper and the lower surfaces of a sliding plate (2); more than two grooves are formed on both the two contact surfaces between the cover plates (1) and the sliding plate (2), to form more than four cavities; lead blocks (3) are embedded in the cavities and have the same size as the cavities; and the upper and the lower cover plates (1) fix the sliding plate (2) and the lead blocks (3) through locking nuts (4) and locking screw rods (5). Compared with the existing shear-type lead damper which has one lead groove, the edge extrusion effect of the lead shear damper is reduced by virtue of the multiple lead grooves.
Description
Technical field:
The utility model relates to a kind of shearing type lead damper, is applicable to the damping control of building structure, belongs to damping control field.
Background technology:
Shearing type lead damper is one type and utilizes the plumbous back of shearing to produce plastic strain and a kind of control device of dissipates vibration energy.Lead shear damper has the following advantages: (1) is unrestricted application life; (2) damping force that provides is reliable; (3) responsive to change in displacement; (4) simple structure does not need to safeguard.Lead shear damper not only can be used for damping, and is the effective way that flexible structure solves vibration problem, and application prospect is very wide.
The application for a patent for invention [200810057382.6] of a kind of " shearing type lead damper " that State Intellectual Property Office has been authorized; As shown in Figure 1, this damper comprises: two cover plates 1 up and down, sliding panel 2 with shear lead 3; Lead is placed in the groove of 2 of cover plate 1 and sliding panels; Utilize the shear strain dissipation energy of lead, simplified the syndeton of lead and cover plate, but have edge extrusion effect problem.
Summary of the invention:
In order to solve the edge extrusion effect problem of shearing lead in the existing lead damper, the utility model provides a kind of multiple-grooved lead shear damper.
For realizing above-mentioned purpose, the design scheme of the utility model is following.A kind of multiple-grooved lead shear damper includes cover plate 1, sliding panel 2, shears lead 3.Cover plate 1 is buckled in the upper and lower surfaces of sliding panel 2, on two contact surfaces of cover plate 1 up and down and sliding panel 2, is equipped with plural groove, and the groove of upper and lower surfaces is relative in twos, forms the cavity more than four; Be embedded in the lead identical 3 at cavity with cavity size; The cover plate 1 of sliding panel 2 upper and lower surfaces fixes with sliding panel 2 and shearing lead 3.
The groove of each above-mentioned contact surface is more than two, has formed the cavity more than four.
The cover plate 1 of sliding panel 2 upper and lower surfaces is fixing with shearing lead 3 with tie down screw 5 and sliding panel 2 through locking nut 4.
The utility model changes a lead bath of existing shearing type lead damper into a plurality of lead baths, has reduced the edge extrusion effect of lead shear damper.

Among the figure: 1, cover plate, 2, sliding panel, 3, shear lead, 4, nut, 5, screw rod, 6, connect the hinge head, 7, band hinge end plate
The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is further specified.
A kind of as shown in Figures 2 and 3 improved lead shear damper includes up and down two cover plates 1, sliding panels 2, shears lead 3.Cover plate 1 is buckled in the upper and lower surfaces of sliding panel 2, on two contact surfaces of cover plate 1 up and down and sliding panel 2, is equipped with two grooves, and last low groove is relative in twos, forms four cavitys; Be embedded in the lead identical 3 at cavity with cavity size.Screw rod 5 is passed cover plate 1 up and down,, fix two cover plates 1 and be sandwiched in sliding panel between the cover plate 12 and shearing lead 3 up and down through locking nut 4 tie down screws 5.2 cover plates 1 weld together with band hinge end plate 7 in use, and sliding panel 2 cuts with scissors 6 and welds with being connected, and is as shown in Figure 4.
The groove of above-mentioned contact surface can and abovely be not limited only to two for two.
