Application number/patent No.: basic level of isolation vibration components such as 200920073177 building structure, bridge, industrial structure; Be specifically related to a kind of steel ball-spring vibration isolation seat structure; This steel ball-spring vibration isolation seat structure comprises bottom base; It is characterized in that said steel ball-spring vibration isolation seat structure also comprises upper cover plate; Described bottom base is provided with a plurality of steel balls even, that be symmetrically distributed and supports described upper cover plate, is fixedly connected with at least one group of vertically disposed damping spring between said bottom base and the upper cover plate; Advantage of the present invention is, and is simple in structure, is convenient to install; Cost is low, and it is convenient to promote; Spacing reasonable, horizontal rigidity is strong; Automatically reset, the remaining displacement in back of shaking is little; Component performance is stable, can forever use.Can widely be applied to bases such as building structure, bridge, industrial structure, with effective level of isolation vibration effect, guarantee superstructure safety so shake after normal use.And for example the mounting method of application number 200710009350 pylons assembles one section body of the tower, and the epimere body of the tower that assembles affixed good this section body of the tower and adjacent this section body of the tower; Follow those sections of movable stand elevates body of the tower through use equipment; Follow again those sections body of the tower positioning supports on the movable stand on bracing frame; Movable stand descends then, and with said method assembling, affixed certain section body of the tower successively from top to bottom, up to remaining final stage body of the tower only; Install one section body of the tower bottom, and assemble affixed this one section body of the tower and tower foundation bottom.Mounting method improvements of practicality of finding to be applicable to heavy construction as yet is technological.
Summary of the invention
The purpose of this invention is to provide a kind of main body vibration isolating suspension mounting method, this method can adapt to the shockproof requirements of heavy construction to syndeton.
Goal of the invention of the present invention realizes through following technical measures: in large span, the Zhongting roof structure installation vibration isolating suspension is set; Vibration isolating suspension bottom built-in fitting buried depth should be less than 20d, and is not less than 250mm, and built-in fitting must vertically be installed; The surface flushes with concrete surface; And must not go out concrete surface by emergence, the horizontal alignment error 1mm of built-in fitting should take reliable measure to guarantee that it is not subjected to displacement or rotates when the joist concrete vibrating.Support the buttress of vibration isolating suspension, its end face horizontal gradient error should not be greater than 5%, and after vibration isolating suspension was installed, the horizontal gradient error of its end face should not be greater than 8%.
The invention has the beneficial effects as follows: commensurate structure spare changes with the work plane condition that main body is expanded with heat and contract with cold or other reasons causes; Overcome bottom surface frictional force uneven phenomenon; Sturdy and durable; For in large span, the Zhongting roof structure installation vibration isolating suspension being set, can guarantee two high buildings independent deformation and can not receive the restriction of conjoined structure in horizontal earthquake.
The specific embodiment
Below in conjunction with the specific embodiment, further set forth the present invention.
Embodiment 1: the technical requirements for major works vibration isolating suspension mounting method comprises: in large span, the Zhongting roof structure installation vibration isolating suspension is set; Vibration isolating suspension bottom built-in fitting buried depth should be less than 20d, and is not less than 250mm, and built-in fitting must vertically be installed; The surface flushes with concrete surface; And must not go out concrete surface by emergence, the horizontal alignment error 1mm of built-in fitting should take reliable measure to guarantee that it is not subjected to displacement or rotates when the joist concrete vibrating.Support the buttress of vibration isolating suspension, its end face horizontal gradient error should not be greater than 5%, and after vibration isolating suspension was installed, the horizontal gradient error of its end face should not be greater than 8%.
In order to guarantee installation quality, require simultaneously: the plan-position at vibration isolating suspension center and the deviation of design attitude should be greater than 5mm, and the apical side height difference on the same buttress between a plurality of vibration isolation should not be greater than 5mm; The vibration isolating suspension junction plate with expose connecting bolt and should take the corrosion protection measure; At the vibration isolating suspension erection stage, the plan-position at reply buttress end face and vibration isolating suspension end face levelness, vibration isolating suspension center and absolute altitude are observed and are kept a record; At Construction stage, should take interim covering protection measure to vibration isolating suspension; At Construction stage, the vertical deformation of reply vibration isolating suspension is observed, and the throw-off distances of superstructure, vibration insulation parts and peripheric fixture is checked.
