Description
Technical field:
The utility model relates to a kind of folded type lead damper, is applicable to the shockproof control of building structure, belongs to shockproof control field.
Background technology:
The application for a patent for invention [200810057382.6] of the one " shearing type lead damper " that State Intellectual Property Office has been authorized, as shown in Figure 1, this damper comprises: upper and lower two cover plates 1, sliding panel 2 and shearing lead 3, lead is placed in the groove between cover plate 1 and sliding panel 2, after utilizing lead to shear, produces plastic strain and dissipate vibrational energy.Lead shear damper has that hysteresis is full, stable performance, simple structure, the advantage such as easy to process, not only can be used for damping, and be the effective way that flexible structure solves vibration problem, application prospect is very wide.
But traditional lead shear damper stroke is less, cannot meet the demand of engineering.For solving the problem of lead shear damper stroke deficiency, the utility application " Long Distances lead shear damper " [201120010275.5] that State Intellectual Property Office has been authorized and " Long Distances plate-type lead shear damper " [201120262875.0] add the stroke of traditional lead shear damper, provide a kind of Long Distances lead shear damper.But existing soft metal damper is due to the size restrictions of damping material, and cause damper to go out fluctuation very large, when displacement is larger, damping is exerted oneself and diminished on the contrary, cannot meet actual requirement of engineering.
Utility model content:
For improving the energy dissipation capacity of existing Long Distances lead shear damper, the utility model provides a kind of folded type lead damper.
For achieving the above object, design scheme of the present utility model is as follows.Folded type lead damper, includes cover plate 1, sliding panel 2, shears lead 3, intermediate plate 6; Sliding panel 2 is buckled in the upper and lower surface of intermediate plate 6, and intermediate plate 6 with two contact surfaces of sliding panel 2 are equipped with rectangular recess, and the groove of contact surface upper and lower surface is relative between two, forms two rectangular cavities; Upper and lower cover plates 1 is buckled in the surface of sliding panel 2, and upper and lower cover plates 1 with two contact surfaces of sliding panel 2 are equipped with rectangular recess, and the groove of contact surface upper and lower surface is relative between two, forms two rectangular cavities; The shearing lead 3 identical with cavity size is embedded at cavity.
Upper and lower cover plates 1 is passed through locking nut 4 and tie down screw 5 and intermediate plate 6, sliding panel 2 and shears lead 3 to fix.
Described shearing lead 3 adopts machine lead.
Benefit of the present utility model and effect are existing shearing type lead damper to carry out superimposed, by carrying out the mode of layering to damping material, increase the shearing area of lead, avoid the damping when displacement is larger to exert oneself inequality, improve the energy-dissipating and shock-absorbing ability of lead damper.

Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Folded type lead damper as shown in Figures 2 and 3, includes cover plate 1, sliding panel 2, shears lead 3, intermediate plate 6; Sliding panel 2 is buckled in the upper and lower surface of intermediate plate 6, and intermediate plate 6 with two contact surfaces of sliding panel 2 are equipped with rectangular recess, and the groove of contact surface upper and lower surface is relative between two, forms two rectangular cavities; Upper and lower cover plates 1 is buckled in the surface of sliding panel 2, and upper and lower cover plates 1 with two contact surfaces of sliding panel 2 are equipped with rectangular recess, and the groove of contact surface upper and lower surface is relative between two, forms two rectangular cavities; The shearing lead 3 identical with cavity size is embedded at cavity.By screw rod 5 through upper and lower cover plates 1 and intermediate plate 6, by locking nut 4 and tie down screw 5, fix two cover plates 1, intermediate plate 6, sliding panel 2 and shear lead 3.In use, upper and lower cover plates 1, intermediate plate 6 cut with scissorss end plate 7 with band and weld together, and sliding panel 2 cuts with scissors end plate 7 and welds with being with simultaneously, as shown in Figure 4.
Described shearing lead 3 adopts machine lead.
