Abstract
The utility model discloses a spanning type construction system with a large-span box girder, which comprises a plurality of temporary piers, two military piers and movable die carriers. A concrete support foundation is arranged at the lower part of the temporary pier; a cushion cap and a plurality of pile foundations positioned below the cushion cap are arranged at the lower part of the military pier; the two military piers are respectively arranged in positions close to two sides of an object to be spanned; the temporary piers are symmetrically distributed on two sides of the temporary piers; and the movable die carriers are supported at the upper parts of the temporary piers or the military piers. By adopting the spanning type construction system as a supporting system for the construction of a continuous girder support, not only the limitation to the traditional door opening method by span can be prevented, but also supporting and fencing can be integrated into a whole, therefore, the complexity that two systems are required to be respectively considered originally is avoided; moreover, the adoption of a movable die carrier method as a supporting and fencing system for spanning is easy to be accepted by a spanned property right unit, and provides convenience for the examination and approval of various procedures; and the system is very beneficial to popularization and application.

The utility model relates to a kind of construction field of wide-span case beam, particularly relates to a kind of great-leap-forward construction system of wide-span case beam.
Background technology
Often run into Construction of continuous beam in present stage railway, the construction of the highway and cross over the situation of existing railway, highway, if adopt traditional door opening method construction, not only be subjected to the restriction of span, also can influence the operation of existing railway and highway, need to coordinate relevant departments' coordinated time, involve examining of some formalities, and construction speed also is subjected to the restriction of existing railway, road travel, very inconvenient.
The utility model content
The purpose of this utility model is at the problems referred to above, proposes a kind of great-leap-forward construction system of wide-span case beam.
The technical solution of the utility model is: a kind of great-leap-forward construction system of wide-span case beam, comprise several interim piers, two military piers and mobile formwork, and described interim pedestal is the concrete brace foundation; Described military pedestal is provided with cushion cap and is positioned at several pile foundations below the cushion cap, and near the dual-side setting of being crossed over thing, described interim pier is symmetrically distributed in the both sides of military pier to described two military piers respectively; Described mobile formwork is supported on interim pier or military socle.
Described mobile formwork comprises girder and the bed die truss that is fixedly installed togather in length and breadth, is provided with bed die on the bed die truss; Be provided with mobile device below described girder, this mobile device is installed in interim pier and military pier upper end.
The front end of described girder is provided with the girder nose girder of certain-length.
Described mobile device comprises pumping plant, vertical jack, displacement chassis, vertical shift mechanism, transverse-moving mechanism, hook, carriage.
The top of described interim pier and military pier is provided with the two-layer bearing beam of going up of crisscross setting, and the described bearing beam top of going up is provided with crossbeam, and described mobile formwork is installed in crossbeam top; The bottom of described interim pier and military pier is provided with the two-layer down bearing beam of crisscross setting, and described bearing beam down is positioned on the concrete brace foundation or on the cushion cap.
The beneficial effects of the utility model
Adopt the support system of great-leap-forward construction system of the present utility model, both can prevent that traditional door opening method is subjected to the restriction of span as the continuous beam rack construction; Can also support, protection is as one, saved loaded down with trivial details that original two kinds of systems consider respectively; In addition, adopt the mobile formwork method as the supporting protection system of crossing over, the property right unit of being crossed over is acceptant, is the condition of providing convenience of examining of various formalities.
