In the related art, the composite column 10 has the characteristics of large vertical bearing capacity and overall rigidity, good plastic deformation capacity and ductility, excellent earthquake resistance, and the like. Among them, the conventional composite post 10 is very complicated in structure and the size of the composite post 10 is large. Therefore, the sectional columns 10 are often transported to the construction site after being segmented under the limitation of transportation, which results in the site consuming a lot of manpower and equipment to dock the segmented columns 10 on site. However, when the composite column 10 is connected to the site, the difficulty of butt joint of the composite column 10 is high due to the mess of site construction, so that the quality of the weld joint of the composite column 10 is poor. When the weld quality of the composite column 10 is poor, it is difficult for the strength of the composite column 10 to meet the strength requirement. To this end, the application proposes a welding method.
The composite column 10 is generally formed by welding the multi-section column assemblies 100 to each other, and if the composite column 10 is manufactured in a factory and transported to a construction site, it is disadvantageous to transport to the construction site due to its large length and weight. Thus, modular column 10 is formed by joining multiple sections of column assembly 100 to facilitate transportation. The specific structure of the column assembly 100 in the present application will be described below. Referring to fig. 2 and 3, in some embodiments, the post assembly 100 includes an inner post 200, an outer post 300, and a rib 400. The outer column 300 has a storage chamber in which the inner column 200 is disposed, and both ends of the rib 400 are respectively connected to the inner wall of the outer column 300 and the outer wall of the inner column 200. Further, the composite column 10 includes a plurality of column assemblies 100, and the plurality of column assemblies 100 are sequentially arranged and connected in the vertical direction.
Continuing with the welding method, referring to FIG. 1, in some embodiments, a welding method is used to weld composite post 10. The welding method comprises the following steps:
s100, temporarily fixing two adjacent column assemblies 100 through a connecting plate 700;
S200, welding the inner columns 200 of the two adjacent column assemblies 100, and then welding the rib plates 400 of the two adjacent column assemblies 100.
Specifically, after two adjacent column assemblies 100 are temporarily fixed by the connection plate 700, the inner column 200 of the column assemblies 100 is welded, and then the rib 400 of the column assemblies 100 is welded. The difficulty of docking is reduced because the adjacent two column assemblies 100 can be temporarily fixed. And the welding sequence from inside to outside can be adopted, so that the quality of the welding line can be higher. Therefore, the welding method can effectively solve the problem of butt joint of the combined column 10 in the construction site, and the welding quality of the combined column 10 is higher.
In the conventional column assembly 100, the inner column 200 is not included in the structural composition. In the conventional column assembly 100, only the adjacent outer columns 300 are welded, so that the welding order of the conventional welding method is generally that the welding is performed from the outside. That is, the outer column 300 is welded. In the present application, since the column assembly 100 has the inner column 200 and the outer column 300, the working efficiency can be improved by welding from the inner column 200 first, thereby saving a certain labor cost.
Further, for the column assembly 100, the inner column 200 and the rib 400 are welded, so that the strength of the adjacent two column assemblies 100 can be improved. And welding the outer columns 300 of the adjacent two column assemblies 100 can further increase the strength of the composite column 10. Thus, in some embodiments, after the rib 400 of the two adjacent post assemblies 100 is welded again, the welding method further includes the step of welding the outer post 300 of the two adjacent post assemblies 100.
To further increase the strength of the composite post 10, it is desirable to increase the strength of the connection at the junction of two adjacent post assemblies 100. Therefore, it is necessary to weld not only the inner column 200, the rib 400, and the outer columns 300, but also the strength of the composite column 10 can be improved by welding the reinforcing plate 500 to the surfaces of the adjacent two outer columns 300. In some embodiments, after welding the outer columns 300 of the adjacent two column assemblies 100, the welding method further includes the step of welding one side of the reinforcement plate 500 to the outer surfaces of the outer columns 300 of the adjacent two column assemblies 100. Wherein, the stiffening plate 500 may be made of metal, and the thickness of the stiffening plate 500 may be between 4mm and 10 mm.
It should be noted that the above-mentioned welding method can adopt symmetrical welding, and by reducing the influence of the welding stress on the installation accuracy of the composite column 10 and the welding sequence from inside to outside, the difficult problem of the on-site butt joint process of the composite column 10 is solved, the welding quality of the welding seam is improved, the construction efficiency is greatly improved, and the construction cost is reduced.
Specifically, in order to improve the quality of the welded seam, the combined column 10 may select the pre-welding preheating temperature and the preheating mode according to the local air temperature and the steel plate thickness before welding, so as to keep the temperature after welding and cool slowly. The welding adopts multilayer multi-pass welding, and can effectively avoid cracks or other defects of welding seams caused by overlarge welding stress.
Further, in some embodiments, the welding method further includes the step of providing the rib 400 with a weld hole prior to welding the inner posts 200 of the adjacent two post assemblies 100. Specifically, a certain space can be reserved in the overselding hole of the rib plate 400, so that the welding of the inner column 200 by workers is facilitated, the work efficiency is improved, and the work difficulty is reduced.
Further, in some embodiments, the welding method further includes the step of providing a liner panel on the back side of the inner column 200 prior to welding the inner columns 200 of the adjacent two column assemblies 100. Specifically, after the liner plate is provided on the back surface of the inner column 200, the welding quality of the adjacent two inner columns 200 can be improved.
In some embodiments, the welding method further includes the step of providing a liner panel on the back of the rib 400 prior to welding the ribs 400 of the two adjacent column assemblies 100. Specifically, after the liner plate is provided on the back surface of the rib plate 400, the welding quality of the adjacent two rib plates 400 can be improved.
Further, it is explained how the connection plate 700 fixes the adjacent two column assemblies 100. Referring to fig. 2, in some embodiments, the ear plate 600 is welded to the surface of the outer column 300, and two connection plates 700 are respectively connected to two sides of the ear plate 600. Wherein the ear plates 600 can facilitate a worker to pull the column assemblies 100, and connect the ear plates 600 on the adjacent column assemblies 100 through the connection plate 700, thereby fixing the adjacent two column assemblies 100.
In some embodiments, after the rib 400 of two adjacent column assemblies 100 is welded again, the welding method further includes the step of cutting away the connection plate 700. Specifically, the ear plate 600 and the connection plate 700 function to temporarily fix the pillar assembly 100, and can be cut off after the reinforcement plate 500 of the outer pillar 300 is welded. The cutting of the ear plate 600 and the connection plate 700 may be flame cutting or mechanical cutting. The rough cut surface can be polished to be smooth after the cutting is completed, thereby improving the aesthetic degree of the composite post 10.
Referring to fig. 4, in some embodiments, the composite post 10 includes a plurality of post assemblies 100 and a plurality of stiffening plates 500. The plurality of column assemblies 100 are sequentially arranged and connected in a vertical direction, the column assemblies 100 include an inner column 200, an outer column 300, and rib plates 400, the outer column 300 has a storage chamber in which the inner column 200 is disposed, both ends of the rib plates 400 are respectively connected to an inner wall of the outer column 300 and an outer wall of the inner column 200, and one side of the reinforcing plate 500 is welded to outer surfaces of two adjacent outer columns 300. Specifically, since the inner column 200 and the outer column 300 are included in the column assembly 100, and the inner column 200 and the outer column 300 are connected by the rib 400. Meanwhile, the outer columns 300 of the adjacent two composite columns 10 are connected by the reinforcing plate 500. Thus, the combined column 10 not only can meet the stress intensity of the structure, but also reduces the wall thickness of the combined column and saves the steel consumption.
Further, referring to fig. 4, in some embodiments, the rib 400 has a plurality of ribs 400 circumferentially disposed around the center of the inner column 200. In particular, the rib 400 may reinforce the connection of the inner column 200 and the outer column 300, thereby indirectly improving the strength of the column assembly 100.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention. Furthermore, embodiments of the invention and features of the embodiments may be combined with each other without conflict.
