Abstract
Provided is a hydraulic pre-compression construction device for a cantilever suspension basket. A variable-cross-section prestressed concrete continuous box girder and a continuous steel member bridge are large in span and advanced in construction process so as to be widely applied to highway engineering and railroad engineering. The hydraulic pre-compression construction device for a cantilever suspension basket comprises a supporting seat (1). A box girder body (2) is arranged at the upper portion of the supporting seat, the box girder body is connected with the suspension basket (3), and the suspension basket is connected with a bottom mould (5) through a lifting rod (4). The hydraulic pre-compression construction device is applied to construction of large-span continuous box girders.
Description
Technical field
The utility model relates to a kind of suspended casting suspended basket hydraulic pressure precompressed construction equipment
Background technology
Variable cross-section prestressed concrete continuous box girder and continuous steel frame bridge are because it is large across the footpath, the ripe wide model employing in highway engineering, railway engineering of construction technology.The type bridge superstructure generally adopts Hanging Basket cantilever method construction, namely at first adopts floor stand method construction initial period, assembly unit Hanging Basket thereon then, and the block-by-block symmetry is built case beam piece spare, closes up in order at last, forms continuous system
Summary of the invention
The purpose of this utility model is to provide a kind of suspended casting suspended basket hydraulic pressure precompressed construction equipment applied widely, simple in structure.
Described purpose is achieved by the following scheme:
A kind of suspended casting suspended basket hydraulic pressure precompressed construction equipment, its composition comprises: bearing, described bearing top are equipped with box girder body, and described box girder body connects Hanging Basket, and described Hanging Basket connects bed die by suspension rod.
Described suspended casting suspended basket hydraulic pressure precompressed construction equipment, described box girder body and described suspension rod are equipped with support, described support comprises pull bar, described pull bar connects oblique fulcrum bar and depression bar, described pole connects described depression bar, and described pull bar one end connects described box girder body, and the described pull bar other end connects described suspension rod, described depression bar one end connects described box girder body, and the described depression bar other end connects described suspension rod.
Described suspended casting suspended basket hydraulic pressure precompressed construction equipment is equipped with oil pump in described box girder body, and described pull bar connects distribution beam, and described distribution beam connecting fluid force feed is pushed up, described hydraulic oil top connection bed die.
Described transport vehicle with adjustable space function, described Hanging Basket comprises lower balancing pole, the hinged left brace of described lower balancing pole, right brace and pole, described left brace, described right brace, described pole be hinged upper balancing pole all, described upper balancing pole connects suspension rod, and described lower balancing pole connects described footstock.
The beneficial effects of the utility model are:
The utility model is used for greatly across the precompressed construction of the large-tonnage suspended casting suspended basket of footpath Construction of Continuous Box Beam and can't realizes the Hanging Basket precompressed construction of preloading, and construction effect is good, speed is fast.
The Hanging Basket good balance effect that the utility model adopts, hydraulic oil pushes up the distance that can be good at adjusting between distribution beam and bed die.
