Abstract
The utility model relates to a bridge damping device, in particular to an embedded damping sheet for a concrete bridge. According to the embedded damping sheet for the concrete bridge, a steel spring spirally penetrates through an upper steel bone beam and a lower steel bone beam; the upper steel bone beam is fixed to an upper bracket steel plate through fixing bolts; the lower steel bone beam is fixed to a lower bracket steel plate through fixing bolts; a beam bottom embedded steel plate is meshed with the upper bracket steel plate through an anchor rod; a cushion supporting steel plate is meshed with the lower bracket steel plate through an anchor rod. A detachable spiral steel spring between fixed parts is utilized, a constructor can fix the fixed parts to upper and lower working surfaces of the bridge through screws, and the installation is simple. In addition, the constructor can select springs in different specifications and damping devices in different numbers according to the sizes of bridges and actual conditions flexibly and conveniently. The bridge damping device is low in cost, obvious in effect and long in service life.
Description
Technical field
The utility model relates to a kind of bridge aseismic devices, specifically a kind of concrete bridge pre-buried type vibration damping sheet.
Background technology
Nearly decades, there is the king-sized earthquake of a lot of destructivenesses (as China Tangshan, Wenchuan earthquake) in the whole world, the common feature of all previous earthquake disaster is: because road and bridge engineering are seriously damaged, cut off earthquake region traffic lifeline, cause the great difficulty of disaster relief work, bring huge life and economic loss.All previous violent earthquake has shown the serious consequence that bridge engineering destroys again and again, has also shown again and again the importance of bridge earthquake resistance research.According to the vertical plinth academician introduction of one of this project leader model, after Tangshan Earthquake in 1976, his teacher, Lee state of Tongji University person of outstanding talent academician have at that time arranged a problem to him: research bridge earthquake resistance technology.I had never expected, 30 years have been spent in this subject study.Since the seventies in last century, bridge earthquake resistance seminar of Tongji University takes the lead in carrying out at home bridge earthquake, Bridge Earthquake Resistance Design theoretical research, has set up China's Loads of Long-span Bridges and the antiseismic theory of beam bridge Space Nonlinear and computational methods, the complicated Grade Separation Project Struture Earthquake Resistant Theory in city and method, the nineties in 20th century, in conjunction with the construction of a collection of national Important Project such as Nanpu Bridge, Yangpu Bridge, two levels of having set up are set up defences, Longspan Bridge Seismic Design Method and the technology of two-stage design, enter after 21 century, at the western science and technology item of Ministry of Communications " the Large Span Bridges Aseismic Design Theory based on lifetime and performance ", " west area highway bridge tensility shock-resistant mechanism and high pier Seismic Design Method, glissando research " etc. subsidy under, in conjunction with the Large scale construction of China's Longspan Bridge and high pier bridge, project team is at Longspan Bridge (cable stayed bridge, suspension bridge, arch bridge) and high pier bridge earthquake resistance and cushion technique aspect carry out innovation research, solved China greatly across, high pier bridge earthquake resistance and damping key technology, for great rivers are crossed over by China, the construction of the high pier bridge of bridge with super-large span and mountain area in straits, bay etc. provides anti-seismic technology support.Usual means are, between bridge pier and bridge, damper has been installed now at present.
And the general hydraulic shock absorber longitudinally arranging that adopts of existing bridge shock absorber, the installation complexity of this damper, needs special power source, and use cost is high, and can only the longitudinal concussion of damping, and therefore actual practicality is not strong.
Summary of the invention
The purpose of this utility model is to provide concrete bridge pre-buried type vibration damping sheet, thus realize easy for installation, damping effect is good, and can bear the load of multiple directions.
To achieve the above object, the utility model adopts following technical scheme: concrete bridge pre-buried type vibration damping sheet, its structure mainly comprises: pre-embedded steel slab, upper bracket steel plate, set bolt, undersetting steel plate, pinner supporting steel plate at the bottom of upper steel frame beam, lower steel frame beam, steel spring, anchor pole, sleeve, beam, and described steel spring is spiral in upper steel frame beam, lower steel frame beam; Described upper steel frame beam is fixed on upper bracket steel plate by set bolt; Described lower steel frame beam is fixed on undersetting steel plate by set bolt;
At the bottom of described beam, pre-embedded steel slab passes through the interlock of anchor pole phase with upper bracket steel plate;
Described pinner supporting steel plate passes through the interlock of anchor pole phase with undersetting steel plate.
Above-mentioned anchor pole is screwed with sleeve.
The beneficial effects of the utility model: utilize spiral steel spring removably between fixed part, constructor can be fixed to fixed part the scope of operation up and down of bridge by screw, install simple.In addition constructor can select the spring of different size and the damping device of varying number according to the size of bridge and actual conditions, flexible.This bridge aseismic devices is with low cost, successful, long service life.And this damping device can be resisted the concussion of multiple direction.
Brief description of the drawings

Fig. 2 is the structural representation of the utility model concrete bridge pre-buried type vibration damping sheet section.
The upper steel frame beam of 1-in figure, steel frame beam under 2-, 3-steel spring, 4-anchor pole, 5-sleeve, pre-embedded steel slab at the bottom of 6-beam, 7-upper bracket steel plate, 8-set bolt, 9-undersetting steel plate, 10-pinner supporting steel plate.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, detailed description of the invention of the present utility model is made a detailed explanation.
Embodiment: concrete bridge pre-buried type vibration damping sheet, its structure mainly comprises: pre-embedded steel slab 6, upper bracket steel plate 7, set bolt 8, undersetting steel plate 9, pinner supporting steel plate 10 at the bottom of upper steel frame beam 1, lower steel frame beam 2, steel spring 3, anchor pole 4, sleeve 5, beam, and described steel spring 3 is spiral in upper steel frame beam 1, lower steel frame beam 2; Described upper steel frame beam 1 is fixed on upper bracket steel plate 7 by set bolt 8; Described lower steel frame beam 2 is fixed on undersetting steel plate 9 by set bolt 8;
At the bottom of described beam, pre-embedded steel slab 6 passes through anchor pole 4 phase interlocks with upper bracket steel plate 7;
Described pinner supporting steel plate 10 passes through anchor pole 4 phase interlocks with undersetting steel plate 9.
Described anchor pole 4 is screwed with sleeve 5.
The utility model can be arranged between bridge and bridge pier by the fixing of the pre-buried and anchor pole 4 of upper bracket steel plate 7, pinner supporting steel plate 10, sleeve 5, is mainly the object in order to reach antidetonation; Because of the core component of antidetonation be one can how nyctitropic volume power spring, therefore can bear except vertical bearing capacity, can also admit the power of horizontal and irregular direction, therefore the utlity model has good applicability.
