Problems solved by technology

In the prior art, when the reference line is drawn and drawn, a square or an additional ruler is often used. This method has the following disadvantages: 1. There are many tools used, two squares and a ruler, and the operation is cumbersome. There are many factors affecting the drawing accuracy; 2. It needs two people to cooperate to complete; 3. When the lead is drawn, one side is the line contact of the square, which is greatly affected by the accuracy of the web itself; 4. The thickness of the flange plate Straightness and flange plate sets have high requirements on deviation
The above shortcomings lead to the problems of low efficiency, large errors and poor economy when drawing and drawing the baseline, which can no longer meet the development requirements of the industry for cost reduction and efficiency increase

Abstract

The invention relates to a method for drawing a reference surface of a single H-type steel member. The method includes steps of (1) assembling a datum line to lead out a special drawing device; (2) drawing a web datum line of the single H-type steel member, to be specifically, drawing the web datum line on a side web of the single H-type steel member by means of the Pythagorean theorem; (3) leading out and drawing a datum line of the upper half of a wing flange of the single H-type steel member; (4) leading out and drawing a datum line on the lower half of the wing flange and the back of the web, connecting and closing all the datum lines to form the reference surface, and completing drawing of the reference surface of the single H-type steel member. The method is simple in processing and efficient in drawing, drawing accuracy is improved, drawing cost is reduced and assembly and mounting quality of the member is effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of steel component manufacture, in particular to a method for drawing a reference plane of a single H-shaped steel component. Background technique [0002] When installing steel structure components, it is necessary to measure the installation accuracy and quality of the components according to the relevant positioning references on the components. Manufacturing accuracy, reducing installation errors, also need to draw a reference line on the best key parts of the components. Generally, the drawing of the reference plane of H-shaped steel members is to determine the drawing of the reference line of the web surface on one side and determine the reference lines of other surfaces by drawing out the marking method to form a surface. In the prior art, when the reference line is drawn and drawn, a square or an additional ruler is often used. This method has the following disadvantages: 1. There are many tools used, two squ...
