Abstract
The invention discloses a box girder cast steel pedestal structure. The box girder cast steel pedestal structure is characterized by comprising two end pedestals symmetrically positioned at two ends and three middle pedestals positioned in the middle; the two end pedestals and the three middle pedestals can be jointed together along the length direction to form the steel pedestal structure; and the end pedestals and the middle pedestals are formed by a steel bottom plate positioned at the lowest end, a three-layer channel steel structure positioned on the steel bottom plate and a steel plate positioned at the top end. The box girder cast steel pedestal structure has the advantages of simple and compact structure and convenient construction, and can be directly laid and mounted during use instead of in-site casting, thereby saving the production time; and the box girder cast steel pedestal structure can be repeatedly moved and used, and therefore the production cost is saved.
Description
Technical field
The present invention relates to bridge engineering, especially relate to a kind of bridge box and beam and build steel pedestal structure.
Background technology
Along with development of technology, in the construction of contemporary bridge engineering, when carrying out the bridge deck construction, select to adopt the form construction of precast beam more and more, promptly earlier crossbeam is built on-site prefabricatedly, lay being transported to the construction point then.Precast beam is according to length, generally is divided into several kinds of specifications such as 20 meters, 25 meters, 30 meters, 35 meters and 40 meters, and wherein, the precast beam width is also with length incremental variations between 0.5 meter to 1 meter.Wherein, the case beam is a kind of form of structure of bridge precast beam, and its inside is hollow shape, and there is the edge of a wing both sides, top, because of similar chest is gained the name.
In the prior art, build precast beam for example during the case beam, generally be build a coupling earlier according to the size of required precast beam earlier the concrete pedestal as brace foundation, and then on the concrete pedestal, lay steel plate, be that bed die is built with the steel plate.This mode, pedestal can't move, and when the job location changes, often just need near the job location, build the concrete pedestal again, causes waste, and pedestal need be cast-in-place simultaneously, often delays the production time.
?
Summary of the invention
Deficiency to above-mentioned prior art; The technical problem that the present invention will solve is: how to provide a kind of case beam of movable type to build steel pedestal structure; Making it can directly lay installation can use, need not cast-in-place, so saved the production time; Can repeat simultaneously to move and use, save cost of production.
In order to solve the problems of the technologies described above, adopted following technical scheme among the present invention:
A kind of case beam is built steel pedestal structure; It is characterized in that; Comprise two end pedestal and three middle pedestals that are positioned at the middle part that are symmetrically located at two ends, said two end pedestals and three middle pedestals can be engaged togather along its length and form steel pedestal structure;
Wherein said end pedestal comprises that spacing parallel arranging along its length is arranged at some steel sole plate A of the bottom; Steel sole plate A exceeds the both sides of pedestal width along the both sides of pedestal width, steel sole plate A top is disposed with first floor steel work A, second layer steel work A and compound steel structure A; Be provided with three couples of 20# channel-section steel A along the pedestal length direction among the said first floor steel work A, the every couple of 20# channel-section steel A is formed by two 20# channel-section steel A of edge-on and involutory setting, and three couples of 20# channel-section steel A are arranged in the two ends and the medium position of pedestal width; The position of corresponding each steel sole plate A all is horizontally arranged with one group of 10# channel-section steel A among the said second layer steel work A; Wherein obtain by two 10# channel-section steel A of edge-on and the opposing setting of opening direction, be positioned at simultaneously on this group 10# channel-section steel A at the end position place that end pedestal and middle pedestal join and be horizontally arranged with some threaded connection hole A near every group of 10# channel-section steel A of the whole end position of steel pedestal; Be set side by side with some 5# channel-section steel A along end pedestal length direction among the said compound steel structure A, the 5# channel-section steel A open side that is positioned at both sides among the compound steel structure A outwards is provided with, and compound steel structure A top is equipped with one deck steel plate A; Wherein all leave the suspension centre space that supplies lifting among second layer steel work A above a steel sole plate A who closes on the whole end position of steel pedestal and the compound steel structure A;
