Abstract
A three/multiple truss main beam of bridge uses a transverse connector 3 to connect a edge main truss 2 and a middle main truss 2, wherein the edge main truss 1 and the middle main truss 2 are arranged with an upper bridge or horizontal connector 4, with a lower bridge or a transverse connector 5 under, the edge main truss 2 and the middle main truss 2 are formed by an upper chord member 6, a lower chord member 7 and a middle web member 8, the middle main truss 2 can be one or several sheets. And nearby two main trusses are connected by the transverse connector 3, to transmit the force between main trusses. The invention uses at least two trusses to bear together, to reduce the force on rod, reduce rod section, reduce the thickness demand and reduce the counter force of base 9. The invention can be used in continuous beam and arc bridge, or the like.
Description
Technical field
The present invention relates to the trussed construction formula girder in a kind of bridge.
Background technology
In recent decades, along with the Chinese society expanding economy, road, bridge are also in develop rapidly, and the bridge location resource is limited, so number of track-lines is on the increase, simultaneously because the busy span of bridge that requires of shipping is also increasing, cause the scale of bridge construction also more and more grander, adopt the rod member of bridge of two trusses stressed often thousands of in addition cross ten thousand tons more common, and existing industry, technical level are difficult to meet the demands in every field such as design, material, manufacturing, transportation, installations, therefore must reduce the stressed of rod member.As adopt common stressed the stressed of each rod member of truss that effectively reduce of truss more than two, make ultra-large bridge under existing industrial foundation, technological level, be achieved.
Summary of the invention
The objective of the invention is at above-mentioned present situation, aim to provide a kind of factory of being convenient to and make, be convenient to transportation, install, construction costs low three or multi-disc trussed construction formula girder more.
The implementation of the object of the invention is, three or multi-disc trussed construction formula girder more, be connected with sway bracing 3 between limit main truss 1 and the middle middle main truss 2, on limit main truss 1 and the middle main truss 2 upper deck of bridge or plane lateral bracing 4 are arranged, under lower floor's bridge floor or plane lateral bracing 5 are arranged, limit main truss 1 and middle main truss 2 are made of upper chord 6, lower chord 7 and middle web member 8, and middle main truss 2 is one or more pieces.
The present invention is made of limit main truss 1 and middle middle main truss 2, and middle main truss 2 is one or more pieces.With sway bracing 3 contact, make stressed can the transmission mutually between main truss between adjacent two main trusses.
The present invention is made of limit main truss 1 and middle middle main truss 2, and middle main truss 2 is one or more pieces.With sway bracing 3 contact, make stressed can the transmission mutually between main truss between adjacent two main trusses.Adopt the truss more than two stressed jointly, it is stressed to have effectively reduced each rod member of truss, reduces bar cross section, reduces the requirement to the main truss slab, is convenient to design, transportation, installs, and reduces construction costs; Reduce the counter-force of bearing 9, be convenient to the design and the buying of bearing.
The present invention can be used for bridges such as continuous beam, arch bridge, cable stayed bridge, suspension bridge.

The specific embodiment
With reference to Fig. 1, the present invention is made of limit main truss 1 and middle middle main truss 2, and limit main truss 1 and middle main truss 2 are made of upper chord 6, lower chord 7 and middle web member 8, and middle main truss 2 is one or more pieces.Owing to adopt the truss more than two stressed jointly, effectively reduce the stressed of each rod member of forming truss, rod member is stressed to diminish, and can reduce bar cross section, considers that the rod member stress factor is little, is convenient to design, transportation, the installation of rod member; Because middle main truss 2 is one or more pieces, the counter-force of two truss being pressed to bridge pier by bearing 9 becomes many places by two places, so can reduce the counter-force of bearing 9, is convenient to the design and the buying of bearing.
Upper deck of bridge or plane lateral bracing 4 are arranged between adjacent two main trusses, have down lower floor's bridge floor or plane lateral bracing 5 to connect, sway bracing 3, lower floor's bridge floor or plane lateral bracing 5 make stressed can the transmission mutually between main truss.Upper deck of bridge or plane lateral bracing 4 or lower floor's bridge floor or plane lateral bracing 5 employing concrete bridge deck or steel bridge face and goosenecks that driving face is arranged; The upper deck of bridge of no driving face or plane lateral bracing 4 or lower floor's bridge floor or plane lateral bracing adopt the plane lateral bracing.
With reference to Fig. 2 a, b, c, d, e, limit main truss 1 or middle main truss 2 structures are Hua Lunshi, triangle, " N " shape, " K " shape, " rice " font structure.
Claims (3)
