Abstract
The utility model provides a damping anchor-box type cable beam anchoring device. The device comprises an anchor bearing plate and a bearing plate which are stacked. Anchoring vertical plates and an inserting plate surrounding a semi-enclosed area are vertically connected onto a plane of the bearing plate; an anchoring plate parallel with the bearing plate and opposite to the bearing plate in position is connected onto the anchoring vertical plates and the inserting plate; and a damping spring is mounted between the anchoring plate and the bearing plate. The damping spring is a belleville spring. A damping pad is further arranged between the anchor bearing plate and the bearing plate. The device is applied to steel cable connected buildings, such as cable-stayed bridges. Pressure of steel cables is transmitted to the device, and deformation produced among the mutually welded plates on the device is absorbed by the damping spring and/or the damping pad. By means of the device, deformation of welding positions under the action of stress is prevented.
Description
Technical field
The utility model relates to building structure field, in particular to the box cable beam anchoring device of a kind of shock-absorbing type anchor.
Background technology
In the raising along with maturation and design theory and the computational methods of the streamlined Plate of Flat Steel Box Girder technology of orthotropic plate, steel box girder stayed-cable bridge is used widely in Large Span Bridges with its unique competitiveness and adaptive capacity.Anchor structure between suspension cable and the steel case beam is a zone that local stress is large, the cable stayed bridge cable-girder anchorage zone is stressed to be concentrated, need and to be distributed to girder section from the huge Suo Li that the suspension cable transmission comes, become the significant points of control design, be directly connected to construction stage and the safety that becomes bridge whole bridge operation stage.The linear flow of should as far as possible exerting all one's strength during design is smooth, avoids occurring excessive stress concentration phenomenon.
At present, the structure of the box anchor device of anchor is used on many long span stayed-cable bridges at home because its supporting capacity is large, design experiences is relatively ripe.
The structural form of steel anchor box formula cable beam anchoring device as shown in Figure 1.Mainly by 11,1 blocks of plates 12 of two anchor risers, 13,1 bearing plates 14 of polylith stiffener and 1 anchor plate 15 form.The anchor head of suspension cable passes anchor plate 15 central circular holes and is anchored on the bearing plate 14, the immense pressure that suspension cable transmits is delivered to the position while welding of the plates such as anchor case bearing plate 14, anchor riser 11, mainly is delivered on the steel anchor box web 16 that this device welded with the form of shearing.
The suspension cable quality is little, flexibility is large, damping is low, very easily vibration-generating under extraneous environmental excitation.And anchor device is to be welded on the steel case web with the polylith plate, and under the vibratory impulse of suspension cable, there is fatigue easily in the commissure.
The utility model content
The utility model aims to provide the box cable beam anchoring device of a kind of shock-absorbing type anchor, has easily tired problem to solve above-mentioned anchor device and steel case web welding position place.
In embodiment of the present utility model, provide a kind of shock-absorbing type anchor box cable beam anchoring device, having comprised: anchor plate and bearing plate, described anchor plate and bearing plate are stacked, on described bearing plate plane, vertically be connected with the anchor riser and the plate that surround semiclosed zone; Be connected with anchor plate parallel with described bearing plate and that the position is relative at described anchor riser and described plate; Between described anchor plate and the described bearing plate damping spring is installed.
Preferably, described damping spring is disk spring.
Preferably, beam also is installed between described anchor plate and bearing plate.
Preferably, described beam by multilayer natural rubber and steel sheet inlay, bonding, sulfuration and the stepped construction that forms.
Preferably, be welded to connect between described bearing plate, anchor plate, anchor riser and the plate.
This application of installation is in the building of cable wire connection, and such as cable stayed bridge, the pressure of cable wire is delivered on the device, and under the effect of various power, the distortion of the generation between each plate that is welded to each other on the device all can be absorbed by damping spring and/or beam.Thereby cracking or the distortion etc. of the welding position that prevents this device under effect of stress.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:

Be connected with anchor plate 21 parallel with described bearing plate 14 and that the position is relative at described anchor riser and described plate;
Between described anchor plate 21 and the described bearing plate 14 damping spring 22 is installed.
Device among the embodiment is applied in the building of cable wire connection, and such as cable stayed bridge, the pressure of cable wire is delivered on the device, and under the effect of various power, the distortion of the generation between each plate that is welded to each other on the device all can be absorbed by damping spring 22.Thereby cracking or the distortion etc. of the welding position that prevents this device under effect of stress.
Preferably, described damping spring is disk spring.
Preferably, between described anchor plate 21 and bearing plate 14, beam 23 is installed also.
Preferably, described beam 23 for beam by multilayer natural rubber and steel sheet inlay, bonding, the stepped construction that forms of sulfuration.
Preferably, be welded to connect between described bearing plate, anchor plate, anchor riser and the plate.
On anchor plate 21, bearing plate 14 and beam 23, have the circular hole of and formed objects concentric with anchor plate 15, be used for holding the cable wire that passes.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
