Problems solved by technology
Due to the limitation of the size of the steel coil or flat steel plate of the raw material, as well as the limitation of the steel structure specification, the arched corrugated steel plate in the slab wall can only be made of arched corrugated steel plates with smaller axial dimensions along the axial direction of the multi-piece pipe gallery. Arranged and welded. In the actual production process, before the assembly and welding, the end faces of the arch angles of the smaller arched corrugated plates have been cut into a bevel, so that the flanges of the longitudinal straight flanges of the plate wall face However, due to the error in the camber of each small arched corrugated plate, and the angle of the cutting slope of the arch angle also has errors, the accumulation of errors is formed after assembly, resulting in the welding of the longitudinal flange surface. The size of the welding gap is different, the welding is difficult, and the welding quality is difficult to guarantee. In addition, the efficiency of this board wall production method is low

Embodiment Construction
[0020] The plate wall on each side of the longitudinal side of the arched corrugated steel plate wall of the prefabricated steel structure pipe gallery is an integral component. The grain direction of the plate is perpendicular to the axis of the pipe gallery; the above-mentioned plate wall is generally 7.5 meters long in the longitudinal direction and 3.5 meters in the circumferential direction, but the size of each corrugated plate formed by the corrugating machine is 1.5 meters × 3.5 meters. , 1.5 meters is the longitudinal direction, so five small-sized corrugated plates should be assembled into a large corrugated steel plate with a longitudinal length of 7.5 meters × 3.5 meters.
[0021] This embodiment discloses a method for producing an arched corrugated steel plate wall of an assembled steel structure pipe gallery, including the following steps:
[0022] Step 1) Forming a straight corrugated steel single-piece plate 1, the wave height and wave pitch of the formed strai...

The invention discloses a production method for an assembling type steel structure pipe rack arch corrugated steel plate wall. According to the method, by means of the mode that corrugated steel plates of an assembling type steel structure pipe rack are welded first and then curved into an arch shape, the overall arch camber of the corrugated steel plates and the gradient of the two end faces of the corrugated steel plates are uniform, and thus flanges can be conveniently assembled and welded. The issues that when the flanges are welded, as the gradients of the end faces of the corrugated steel plates are not uniform, the welding seams of contact faces are different in size, and welding is difficult can be avoided.
Description
technical field [0001] The invention relates to a method for producing a steel plate for a pipe gallery, in particular to a method for producing an arched corrugated steel plate wall of an assembled steel structure pipe gallery. Background technique [0002] The applicant has been committed to the scientific research, production and application of the prefabricated underground steel structure pipe gallery, in which the upper, lower, left and right board walls of the prefabricated underground steel structure pipe gallery are corrugated steel plates with outer arches. The four edges of the corrugated steel plate are welded with flanges, and the flanges include longitudinal straight flanges and circumferential arch flanges. The axial length of each panel wall is about 6 meters to 10 meters wide, and the width is about 3.5 meters to 5 meters. Due to the limitation of the size of the steel coil or flat steel plate of the raw material, as well as the limitation of the steel struc...
