Abstract
The invention discloses a viaduct base. The viaduct base mainly comprises a viaduct base body, viaduct frame supports, viaduct face bases, supporting arms and a fixed linkage shaft. The two viaduct frame supports are arranged on the viaduct base body in parallel, the viaduct face bases are arranged on the viaduct frame supports respectively, a viaduct body is arranged on the two viaduct face bases, triangular fixing frames are arranged below the viaduct face bases respectively, drag steel chains are arranged above the viaduct face bases respectively, the fixed linkage shaft is arranged between the top ends of the two viaduct frame supports, the two supporting arms are arranged between the two viaduct frame supports and below the triangular fixing frames, two supporting shafts are arranged between the two supporting arms, and stand columns are arranged between the upper supporting arm and the two viaduct face bases. A viaduct frame is firm and light in weight, and therefore the great pressure of the viaduct body on the ground is reduced, the viaduct base is suitable for construction of urban viaduct roadways and vital communication line overpasses, the technology is simple, and installation is convenient.
Description
Technical field
The invention belongs to bridge field, particularly relate to a kind of viaduct pedestal.
Background technology
Crane span structure is widely used in traffic main artery, and in traffic main artery and city, linking-up road plays an important role, and bridge formation technology is also constantly more being entered, there is now a kind of crane span structure, the building being applicable to urban viaduct road and traffic main artery overpass bridge uses, and technology is simple, easy for installation.
Summary of the invention
In order to increase the practicality of prior art, the object of this invention is to provide a kind of crane span structure of the present invention firm, crane span structure weight reduces, thus alleviates the viaduct pedestal of the body of a bridge to the weight on ground.
The present invention takes following technical scheme to realize: a kind of viaduct pedestal, it mainly comprises bridge base, crane span structure bearing, bridge floor base, trailing arm and fixing shaft coupling, described crane span structure bearing settlement two, be installed in parallel on bridge base, a bridge floor base installed by every root crane span structure bearing, pontic is arranged on two bridge floor bases, all arrange below two bridge floor bases and three corner steadies are installed, all arrange above two bridge floor bases and a dilatory steel chain is installed, top between two crane span structure bearings is provided with a fixing shaft coupling, two trailing arms are installed between two crane span structure bearings and below three corner steadies, two back shafts are installed between two trailing arms, between a upper trailing arm and two bridge floor bases, column is installed.
Described bridge floor base can automatic telescopic forward or backward.
The present invention has following beneficial effect in sum: crane span structure of the present invention is firm, and crane span structure weight reduces, thus alleviates the weight of the body of a bridge to ground, and the building being applicable to urban viaduct road and traffic main artery overpass bridge uses, and technology is simple, easy for installation.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of viaduct pedestal, it mainly comprises bridge base 1, crane span structure bearing 2, bridge floor base 3, trailing arm 4 and fixing shaft coupling 6, described crane span structure bearing 2 arranges two, be installed in parallel on bridge base 1, a bridge floor base 3 installed by every root crane span structure bearing 2, pontic 7 is arranged on two bridge floor bases 3, all arrange below two bridge floor bases 3 and three corner steadies 5 are installed, the top be provided with between a dilatory steel chain 10, two crane span structure bearings 2 is all set above two bridge floor bases 3 a fixing shaft coupling 6 is installed.
Detailed description of the invention: be provided with between two crane span structure bearings 2 and below three corner steadies 5 between two trailing arms, 4, two trailing arms 4 and be provided with two back shafts 8, be provided with column 9 between a upper trailing arm 4 and two bridge floor bases 3.
Described bridge floor base 3 can automatic telescopic forward or backward.
The above is the embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in the present patent application scope change or modify, and are included in patent claim of the present invention.
