A manufacturing method for a special-shaped node in multi-dimensional space

Abstract

The present invention discloses a manufacturing method for a multi-dimensional space special-shaped node. Select a circular tube, six box-shaped corbels, two circular tube inner partitions, six insertion plates, and six corbel inner partitions. Vertically insert the two circular tube inner partitions into the inner sides of the upper and lower ends of the circular tube respectively, and fix the circular tube inner partitions to the inner sides of the upper and lower ends of the circular tube by welding. Through the study of all nodes, the present invention finds that from the top view, the extension line of the connection line between the control point B and the control point C of each box-shaped ox horn passes through the standard point A. Therefore, it is proposed to use the standard point A as the reference point, first measure the height differences between the control point B and the control point C and the standard point A respectively, and then measure the projection distances between the control point B and the standard point A and between the control point C and the standard point A, so as to finally determine the specific positions of the control point B and the control point C.

Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing special-shaped steel structures, and in particular to a method for manufacturing multi-dimensional special-shaped nodes. Background Art

[0002] With the continuous maturity of technologies in the field of steel structures, people's requirements for the appearance of steel structure shapes are also getting higher and higher. For some high-level architectural designs, in terms of production technology, it is necessary to meet people's aesthetic requirements and achieve mass production, so as to speed up the construction progress and reduce the manufacturing cost. This poses a huge challenge to steel structure construction technologies.

[0003] Space grid structures can achieve arbitrary curvature shapes of buildings and are widely used. Space grid structures generally have square tube and round tube cross-sections. Due to the characteristics of multi-space, multi-angle, small volume, and high precision of the intersection nodes, the most crucial factor in ensuring their manufacturing quality is the structure of the nodes;

[0004] Currently, the nodes are formed by splicing multiple box-shaped horns together. Each box-shaped horn corresponds to a square tube, and the box-shaped horns need to be welded to the round tubes. Moreover, due to the special curved surface of the building, the angles between each box-shaped horn and the round tube are all different. This causes great trouble in producing the nodes (the welded parts of the box-shaped horns and the round tubes). In order to ensure that the angles of each box-shaped horn meet the requirements of customers, a set of corresponding jigs need to be produced for each node. Each part of the jig accurately limits the position of each point of the box-shaped horn, which makes it very convenient for workers during production. However, correspondingly, it is necessary to produce the same number of jigs with different size parameters, and each node requires a corresponding jig. This also means that after the jig is used, it can only be recycled as scrap iron. This also results in a large number of production jigs being required for producing the nodes, and a large number of jigs will be wasted, and the construction period is long and the production efficiency is low. There is a need for a production method specifically designed for special-shaped building nodes to solve the problems of low production efficiency of nodes and waste of a large number of jigs.

[0005] Therefore, we propose a method for manufacturing multi-dimensional special-shaped nodes to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a method for manufacturing multi-dimensional special-shaped nodes to solve the problem in the production of existing special-shaped steel structure nodes in the above background art that each node requires a corresponding set of jigs, resulting in a sharp increase in production costs and low production efficiency. The technical solution of the present invention addresses the technical problem of overly single existing technical solutions and provides a solution significantly different from the prior art.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A method for manufacturing a multi-dimensional space special-shaped node, comprising the following steps:

[0009] Step 1: Select a circular tube, six box-shaped corbels, two circular tube inner partitions, six insertion plates, and six corbel inner partitions;

[0010] Step 2: Vertically insert the two circular tube inner partitions into the inner sides of the upper and lower ends of the circular tube respectively, and fix the circular tube inner partitions at the inner sides of the upper and lower ends of the circular tube by welding;

[0011] Step 3: Vertically assemble the six insertion plates on the outer wall of the circular tube and perform welding;

[0012] Step 4: Assemble the six box-shaped corbels to the outside of the circular tube. The method for assembling the corbels includes the following steps:

[0013] S1: Taking the center of the circular tube inner partition as the reference point, designated as the standard point A, draw the center line of the lower plane of the box-shaped corbel. The front point of the center line is the control point B, and the rear point of the center line is the control point C;

[0014] S2: Taking the standard point A as the reference point, measure the height difference between the control point B and the standard point A, and measure the height difference between the control point C and the standard point A;

[0015] S3: Taking the standard point A as the reference point, measure the distance after the projection of the control point B and the standard point A on the ground, and then measure the distance after the projection of the control point C and the standard point A on the ground, and finally determine the positions of the control point B and the control point C relative to the standard point A in space;

[0016] S4: Select any edge angle of the box-shaped corbel, denoted as point D, mark the same point as point D1 on the drawing, and measure the distance after the projection of point D1 and the standard point A;

[0017] S5: Rotate the box-shaped corbel with the connection line between the control point B and the control point C as the axis, and make point D coincide with point D1 in the projection direction, and finally completely determine the specific position of the box-shaped corbel;

[0018] Step 5: Weld between the box-shaped corbel and the circular tube, and then weld between the box-shaped corbel and the insertion plate;

[0019] Step 6: Insert the corbel inner partition into the box-shaped corbel and then weld the two;

[0020] In a further embodiment, the points D and D1 in the S4 select the edge angles on the side of the box-shaped corbel away from the circular tube.

[0021] In a further embodiment, in the fourth step, the box-shaped bracket is spliced between two plug plates.

[0022] In a further embodiment, in S1, the standard point A is located on the extension line of the projection connection line between the control point B and the control point C.

[0023] In a further embodiment, in the second step, the inner partition of the circular tube is not in the same plane as the upper and lower end faces of the circular tube.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. By studying all the nodes of the present invention, it is found that from the top view, the extension line of the connection line between the control points B and C of each box-shaped horn passes through the standard point A. Therefore, it is proposed to use the standard point A as the reference point. First, measure the height differences between the control points B and C and the standard point A respectively, and then measure the projection distances between the control point B and the standard point A and between the control point C and the standard point A, so as to finally determine the specific positions of the two points of the control points B and C. On the basis of determining the control points B and C of the box-shaped horn, taking the connection line of these two points as the rotation axis, rotate the entire box-shaped horn, and determine the position of any edge projected with the standard point A as the center on the drawing and record it as D1. Take the edge at the same position in the actual product as D. When rotating the box-shaped horn, if the D edge in the actual product coincides with the position of the D1 edge in the projection on the drawing, the accurate position of the entire box-shaped horn is determined. In summary, the present invention determines the accurate position of the box-shaped horn in space without any jig, and does not need to position each point of the box-shaped horn, saving the time for making jigs for each node when making nodes, improving the overall processing efficiency, and not wasting any jig, saving materials and shortening the actual production time of the product.

[0026] 2. The present invention combines the design drawing to find the rule, and makes the seemingly irregular bracket angles in a planned and traceable way. Taking the center of the lower end face of the circular tube as the positioning reference, arrange the center line of the bracket cover plate to solve the positioning difficulties such as many brackets, uneven distribution, and diverse torsion angles at the intersection node. Secondly, because this manufacturing method is traceable and has high dimensional accuracy, it solves the problem that the manufacturing accuracy of the processing factory cannot meet the requirements and the components need to be modified by welding constantly at the installation site, reduces the operation risk, greatly reduces the processing time and the use of mechanical jigs, reduces the production cost, and can ensure the forming appearance size of the components.

Embodiment

[0037] Please refer to Figure 1-7 , in an embodiment of the present invention, a manufacturing method for a multi-dimensional space special-shaped node includes the following steps:

[0038] Step 1: Select a round tube, six box-shaped brackets, two inner round tube partitions, six insertion plates, and six inner bracket partitions.

[0039] Step 2: Vertically insert the two inner round tube partitions into the inner sides of the upper and lower ends of the round tube respectively, and fix the inner round tube partitions at the inner sides of the upper and lower ends of the round tube by welding.

[0040] Step 3: Vertically assemble the six insertion plates on the outer wall of the round tube and perform welding.

[0041] Step 4: Assemble the six box-shaped brackets to the outside of the round tube, and the box-shaped brackets are spliced between the two insertion plates. The assembly method of the brackets includes the following steps:

[0042] S1: Taking the center of the inner round tube partition as a reference point, designated as the standard point A, draw the center line of the lower plane of the box-shaped bracket. The front point of the center line is the control point B, and the rear point of the center line is the control point C. The standard point A is located on the extension line of the projection connection line between the control point B and the control point C.

[0043] S2: Taking the standard point A as a reference point, measure the height difference between the control point B and the standard point A, and measure the height difference between the control point C and the standard point A.

[0044] S3: Taking the standard point A as a reference point, measure the distance after the projection of the control point B and the standard point A on the ground, and then measure the distance after the projection of the control point C and the standard point A on the ground, and finally determine the spatial positions of the control point B and the control point C relative to the standard point A.

[0045] S4: Select the edge angle of the box-shaped bracket far from the round tube, denoted as point D, mark the same point as point D1 on the drawing, and measure the distance after the projection of the point D1 and the standard point A.

[0046] S5: Rotate the box-shaped bracket with the connection line between the control point B and the control point C as the axis, and make the point D coincide with the point D1 in the projection direction, and finally completely determine the specific position of the box-shaped bracket.

[0047] Step 5: Weld between the box-shaped bracket and the round tube, and then weld between the box-shaped bracket and the plug plate;

[0048] Step 6: Insert the internal partition of the bracket into the box-shaped bracket and then weld the two together.

[0049] It should be added that, due to the special-shaped curved surface building, its building shape is irregular compared with traditional buildings. Therefore, the lengths of each H-shaped steel and the specific connection angles are different, and the positions of the brackets at each node are also different. In order to ensure a perfect fit of the node positions, the sizes of each bracket are completely different.
