Abstract
The utility model relates to a steel girder used in a bridge construction, in particular to a mobile mold carrier self-floating lower shouldering girder used for erecting segmental girders. The self-floating lower shouldering girder is formed by connecting a steel girder (1) with coupling systems among girders (3) and lifting lugs (2), and is characterized in that the steel girder is a non-uniform cross-section sealed box steel girder. The non-uniform cross-section sealed box steel girder (1) is welded with the coupling systems among the girders (3), and both ends of the box steel girder (1) are suspended on the transverse lever of the main steel truss girder of a bridge fabrication machine by being connected with the lifting lugs (2) through pin rolls (4). The steel girder used in the bridge construction adopts the self-floating lower shouldering girder formed by welding the box steel girder with coupling systems among the girders on a water working surface, and has the advantages of simple structure, convenient assembly and disassembly as well as convenient transportation. When passing through a hole, the lower shouldering girder is lifted to the water working surface by utilizing a girder-lifting crane and hauled to the next hole in position by utilizing the self-floating of the shouldering box steel girder, thereby reducing the construction difficulty.
Description
Technical field
The utility model relates to the girder steel that uses in a kind of bridge construction, specifically a kind ofly is used for shoulder pole girder under the mobile formwork self-floating that beam sections sets up.
Background technology
The spandrel girder that is used for mobile formwork bridge fabrication machine at present mostly is horizontal sliding or suspending way, before the via hole with the outside horizontal sliding of spandrel girder or removed and be transported to next position, hole.For the mobile formwork bridge fabrication machine in the marine site construction, the mode that spandrel girder is removed just needs multiple haulage device cooperation to remove, and therefore the cost that drops into is big, and efficient is low.Therefore inventing a kind of novel steel truss girder that can conveniently transport and remove is highly profitable.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, provides shoulder pole girder under a kind of mobile formwork self-floating to satisfy the needs of rapid construction.
The technical solution of the utility model is achieved in that it is formed by connecting by bracing (3) between girder steel (1), beam and hanger (2), is characterized in that: described girder steel is the sealed box steel beam of variable cross-section; Bracing (3) is welded between sealed box steel beam of variable cross-section (1) and beam, and box steel beam (1) two ends connect hanger 2 by bearing pin (4) and hang on the cross bar of bridge fabrication machine master steel truss girder.
The utility model adopts shoulder pole girder under the self-floating that the bracing assembly welding forms between box steel beam and beam in the waters scope of operation, and it has advantage simple in structure, the dismounting convenient transportation.Utilize the bale handle loop wheel machine will descend shoulder pole girder to winch to the waters face during via hole, utilize the floating certainly of shoulder pole steel case beam, haul in placely, can reduce difficulty of construction to next hole.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model is formed by connecting by bracing (3) between girder steel (1), beam and hanger (2), it is characterized in that: described girder steel is the sealed box steel beam of variable cross-section; As shown in Figure 3, bracing (3) is welded between sealed box steel beam of variable cross-section (1) and beam, and box steel beam (1) two ends connect hanger (2) by bearing pin (4) and hang on the cross bar of bridge fabrication machine master steel truss girder.
Reassembling type hanger (2) will descend shoulder pole girder to be hung on the cross bar of main steel truss girder, and working load is evenly passed to the main truss beam.The two ends of following shoulder pole girder have the pin shaft hole that is connected with hanger, consider that bearing pin is long and heavy, are provided with the bearing pin sleeve so that bearing pin is installed at the pin shaft hole place.Establish the lifting hanger simultaneously at the two ends of shoulder pole girder to make things convenient for loop wheel machine lifting shoulder pole girder.The end face of shoulder pole girder is provided with the junction plate that is connected usefulness with the steel cushion block, and lays the 50t hydraulic jack, and unloading is used when being used for the absolute altitude adjustment of section box girder and grading tension concrete box girder prestressing tendon.Shoulder pole back both sides also are provided with junction plate, carry out bolt with operation platform, and the operation platform bottom completely hangs safety net.
Set up water surface operation area for Longspan Bridge, hanging at bridge fabrication machine needs to descend shoulder pole girder to connect during the square pier place before the shoulder pole girder vertical shift is inserted into and removed pier, owing to exist many group shoulder pole girder upper air installings to cross pier, has a big risk, cost height, construction progress delay, and it is sealed to descend shoulder pole girder to be designed to for this reason.Make full use of steel case beam at the certainly floating (F of the water surface
Floating＞G
Deadweight) principle, haul in placely to next hole, and then shoulder pole girder promote to be installed, avoided upper air installing repeatedly to cross the bridge pier hole, thereby reduced the difficulty of construction, reduced construction cost and construction period.
Claims (2)
1, shoulder pole girder under a kind of mobile formwork self-floating, it is formed by connecting by bracing (3) between girder steel (1), beam and hanger (2), it is characterized in that: described girder steel is the sealed box steel beam of variable cross-section.
2, shoulder pole girder under the mobile formwork self-floating according to claim 1, it is characterized in that: bracing (3) is welded between sealed box steel beam of variable cross-section (1) and beam, and box steel beam (1) two ends connect hanger 2 by bearing pin (4) and hang on the cross bar of bridge fabrication machine master steel truss girder.
