Splicing construction method and splicing device for steel truss girder bridge sections
The invention relates to the technical field of steel truss girder bridges, in particular to a splicing construction method and a splicing device for steel truss girder bridge sections. The splicing construction method of the steel truss girder bridge sections comprises the following steps that a horizontal splicing jig frame and a vertical splicing jig frame are erected on a concrete T-girder bridge deck, and the horizontal splicing jig frame and the vertical splicing jig frame are parallel to the concrete T-girder bridge deck; the web members and the chord members are assembled into a truss piece frame on the horizontally-assembled jig frame; then the assembled truss piece frames are moved to the vertical assembling jig frame and fixed, a connecting piece is arranged between every two opposite truss piece frames, the two ends of each connecting piece are fixedly connected with the two corresponding truss piece frames respectively, so that the left truss piece frame and the right truss piece frame are fixedly connected through the connecting pieces, and the steel truss girder bridge section can be obtained. The horizontally-spliced jig frame and the vertically-spliced jig frame are parallel to the concrete T-beam bridge deck, so that the situation that the horizontally-spliced jig frame and the vertically-spliced jig frame are lifted to enable the height of the truss to be increased, and aerial work occurs can be avoided, and construction danger is effectively reduced.
本发明涉及钢桁架梁桥技术领域，具体涉及一种钢桁架梁桥节段的拼装施工方法及拼接装置。该钢桁架梁桥节段的拼装施工方法，包括以下步骤：在混凝土T梁桥面上搭设卧拼胎架和立拼胎架，卧拼胎架和立拼胎架与混凝土T梁桥面相平行；在卧拼胎架上，将腹杆和弦杆拼装为桁片架；随后将拼装完成的桁片架移动至立拼胎架上，并进行固定，在相对的两个桁片架之间设置连接件，连接件的两端分别与两个桁片架固定连接，以使左右桁片架通过连接件固定连接，即可得到钢桁架梁桥节段。使卧拼胎架和立拼胎架与混凝土T梁桥面相平行，从而可避免将卧拼胎架和立拼胎架抬高使桁架高度升高，出现高空作业的情况，有效的减低了施工危险性。
