Embodiment 1

[0082] The elevation support plate 9 includes a base and a top support block, and the base and the bottom of the top support block are fastened and connected by strip holes. By adjusting the height of the top support block relative to the base, the positions of the two strip holes are locked, thereby realizing the elevation support. Plate 9 height adjustment.

Embodiment 2

[0084] In the above embodiment, further: the elevation brace 9 is a support block structure; the bottom of the support block is provided with a screw, and the screw is vertically screwed to the V-shaped positioning surface of the V-shaped tire frame 8. By adjusting the elevation brace 9 The screw rod is unscrewed to adjust the alignment of the tooling positioning and supporting arch rib web 3;

[0085] That is, by adjusting the vertical height of the elevation support plate 9 relative to the surface of the V-shaped tire frame 8, a V-shaped support surface is formed.

[0086] On this basis: the two sides of the special tire frame 7, that is, the left and right symmetrical sides of the outside of the V-shaped tire frame 8, are respectively vertically provided with safety side blocks 10.

[0087] The inner side of the top of the safety side block 10 faces the horizontal direction and is provided with a horizontal tightening device 11 that can adjust the horizontal extension lengt...

Abstract

The invention provides a manufacturing method of a polygonal basket arch bridge with plug-in lug plates and a tool thereof. The manufacturing method comprises the following steps: adjusting and detecting the tool; a side lower web plate is assembled and fixed; side partition plates are assembled and fixed; a movable side lower web plate is assembled; the movable side partition plates are assembled; assembling the top plate and the bottom plate; assembling a left upper web plate and a right upper web plate; inserting type lug plates are assembled; and box type welding. The device is simple in structure, convenient to use, efficient in positioning, safe, reliable, ideal in universality and efficient in construction, reference is provided for manufacturing of similar profile steel components, and the problems that the large section line shape is difficult to control and the angle of the lug plate is difficult to control are solved; and the production efficiency is improved, certain economic benefits are obtained, and the device has extremely high practical and popularization values and is suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of manufacturing a basket arch bridge for fixed buildings, and in particular relates to a manufacturing method and tooling for a polygonal basket arch bridge with plug-in lug plates. Background technique [0002] The basket-type arch bridge is a statically determinate outside the body and ultra-statically indeterminate inside the bridge, which has the advantages of small structural height and low total cost. In recent years, the use of basket-type arch bridges in urban landscape bridges has become more and more common, the cross-section forms have become more and more diverse, and the anchorage forms using lifting lugs have become more and more widespread. [0003] (See figure 1 ) In the past, the top plate 1, bottom plate 2, and web plate 3 of the basket arch bridge section were mostly rectangular sections. However, for the polygonal basket arch bridge with plug-in lugs, the structural section of the bask...
