Embodiment Construction

[0022] Attached to the following Figure 1-2 This application will be described in further detail.

[0023] The embodiments of the present application disclose a segmented steel truss bridge and a construction method thereof.

[0024] like figure 1 As shown, a segmented steel truss bridge includes a bridge body 1, and the bridge body 1 includes a beam 2, a bottom beam 3 and a support member 5, and between the beam 2 and the bottom beam 3 along the length of the beam 2 is provided with several groups of supports Piece 5.

[0025] like figure 1 , figure 2 As shown, the support 5 includes a first connecting rod 6, a second connecting rod 7, an inclined web rod 4, a slot 8, a plug 9, a plug hole 10, a plug block 11 and a first inclined surface 12, the first The connecting rod 6 is fixedly connected to the lower surface of the beam 2 , and two first connecting rods 6 are fixedly connected to the lower surface of the beam 2 . The second connecting rod 7 is fixedly connected t...

Abstract

The present application relates to a segmented steel truss bridge, comprising a bridge body, the bridge body comprising a cross beam, a bottom beam, an inclined web rod and a support piece, the support piece includes a first connecting rod fixedly connected to the lower surface of the cross beam, and a first connecting rod fixedly connected to the bottom beam The second connecting rod on the upper surface, the slot opened on the upper surface of the second connecting rod, the insert block fixedly connected to the lower end face of the inclined web rod, the plug hole opened on the lower surface of the first connecting rod, the fixing Connect the plug-in block on the upper end face of the inclined web rod and the first inclined surface opened on the opposite sides of the two plug-in blocks, then weld the segmented beam on the ground, and then hoist the beam by a crane. Under the action of the first inclined surface, the plug-in block on the inclined web rod is inserted into the plug-in hole on the first connecting rod, and then the first connecting rod and the inclined web rod are welded together, and the whole beam can be welded together. The hoisting also facilitates the positioning and connection of the inclined web bar and the beam, and improves the work efficiency.

Description

technical field [0001] The present application relates to building structures, in particular to a segmented steel truss bridge and a construction method thereof. Background technique [0002] Steel truss girder bridge is a structural form in which a solid-web steel plate girder bridge is hollowed out according to certain rules. It consists of braking connection, bridge deck, support and bridge pier (abutment). [0003] In the manufacturing process of the existing steel truss girder bridge, the steel truss girder bridge is fabricated in sections in the workshop, and then transported to the construction site by vehicles, and then the sectioned steel truss girder bridge is welded and erected. [0004] In view of the above-mentioned related technologies, the inventor believes that during the welding process of the existing segmented steel truss bridge, the operator needs to perform the welding operation at high altitude for a long time, which increases the risk of the operator....
