Embodiment Construction

[0015] Such as Figure 1 to Figure 3 The steel pipe arch shown includes a square tube transition piece, which is trumpet-shaped and has a certain radian, and arc-shaped semicircular tubes 1 with a radian are welded on both sides of the square tube transition piece, and a cross-sectional gradient is formed through the above structure. Radian oblate steel pipe arch, such as figure 2 The square tube transition piece shown includes an upper wall plate 2, a lower wall plate 3, a left web plate 4 and a right web plate 5, the upper wall plate 2 and the lower wall plate 3 are isosceles trapezoidal, the left web plate 4 and the right web plate The plate 5 is equal in width and has a certain radian. The edges of the upper wall plate 2, the lower wall plate 3, the left web plate 4 and the right web plate 5 are welded together to form a square tube, wherein the upper wall plate 2 and the lower wall plate 3 are opposite to each other. , the left web 4 and the right web 5 are opposite, be...

Abstract

The invention discloses an oblate variable-cross-section steel pipe arch and a manufacturing process thereof. The steel pipe arch comprises a trumpet-shaped square pipe transition piece with radian, wherein arc-shaped semicircular pipes are welded to the two sides of the square pipe transition piece respectively. The manufacturing process comprises the following steps that a, two webs which are equal in width and radian are manufactured, two isosceles trapezoid wall plates with the same specification are manufactured, edges close to the waists of the wall plates are welded to the arc edges ofthe webs so as to allow the wall plates and the webs to define a square pipe with the radian and a gradually-changing hole diameter, a uniform-section round steel pipe is prepared and bent to form a bent pipe with radian consistent with the radian of the webs, and then the bent pipe is cut into two semicircular pipes along the axis of the bent pipe, wherein the orthographic projection of the axisis a straight line, and the diameter of the round steel pipe is equal to the distance between the two wall plates that form the square pipe; and b, the cutting edges of the two semicircular pipes arewelded to the waist edges of the wall plates correspondingly, so the oblate variable-cross-section steel pipe arch is formed.

Description

technical field [0001] It involves bridge manufacturing, especially the steel pipe arch structure and manufacturing process of steel arch bridges. Background technique [0002] In recent years, with the rapid development of my country's economy, the manufacturing technology of steel bridges has become increasingly mature. Bridge design is not only satisfied with solving traffic problems, but bridge design aesthetics has also been placed in an important position. One of the manifestations is the widespread appearance of landscape bridges. Steel arch bridges have both good stability and good landscape. The steel arches on traditional steel arch bridges are mostly arc-shaped with equal section and single shape. Contents of the invention [0003] In order to solve the deficiencies in the prior art and provide a unique shape and good performance oblate circular cross-section steel pipe arch and its manufacturing process, the technical solution adopted in the present invention i...
