Construction steel vertical post node structure

Abstract

The invention provides a construction steel vertical post node structure, belonging to the field of construction structures. The structure comprises an upper vertical post and a lower vertical post which have the same cross section shape, and a plurality of connecting plates which are arranged between inner cavities of the upper vertical post and the lower vertical post, wherein the connecting plates are adhered on walls of the inner cavities of the upper vertical post and the lower vertical post for a circle, and are fixedly connected with the upper vertical post and the lower vertical post through fasteners. In the invention, the structure is screwed and fixed with the upper vertical post and the lower vertical post by an upper connecting flake, a lower connecting flake and the connecting plates, the construction steel vertical post node structure has high standard degree and good interconvertibility, is convenient to transport and assemble, and can improve the construction efficiency.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a building steel vertical column node structure. Background technique [0002] like figure 1 , figure 2 As shown, the traditional building steel vertical column joint structure is welded by two square vertical columns 1' arranged at the upper and lower positions. Before welding, the eight upper lugs 2' and the eight lower lugs 3' are respectively welded. Welded on the four sides of the outer surface of the upper and lower vertical columns 1', the eight lower lugs 3' correspond to the positions of the eight upper lugs 2' respectively, and the four strip-shaped welding substrates 4' are welded respectively. Between the inner cavity walls of the upper and lower type vertical columns 1', this is the butt welding of the upper and lower type vertical columns 1', and then each corresponding upper lug plate 2', The lower lugs 3' are respectively connected with the upper and lower e...

[0002] like figure 1 , figure 2 As shown, the traditional building steel vertical column joint structure is welded by two square vertical columns 1' arranged at the upper and lower positions. Before welding, eight upper ear plates 2' and eight lower ear plates 3' are respectively Welded on the four surfaces of the outer surface of the upper and lower vertical columns 1', the eight lower ear plates 3' correspond to the positions of the eight upper ear plates 2' respectively, and weld the four strip-shaped welding base plates 4' respectively Between the upper and lower type vertical columns 1', this is the butt welding of the upper and lower type vertical columns 1', and then each corresponding upper ear plate 2', The upper and lower ends of the lower ear plates 3' are fixedly connected with the upper and lower ends of a connecting plate 5' by bolts, and then the contact surface of a circle between the upper and lower vertical columns 1' is welded. After the welding is completed, the upper and lower The ear plates are sawed off from the upper and lower vertical columns respectively, so that the connecting plate 5' is also removed from the space between the upper and lower vertical columns 1', and finally the position between the upper and lower vertical columns 1' is corrected. On the one hand, this kind of structure requires a lot of welding to realize the connection, resulting in more thermal stress parts, reducing the performance of the material, and at the same time, the processing time is long and the cost is high; on the other hand, the structure formed by this welding method forms an overall large Components are neither conducive to transportation nor to standardized production. If a part is processed on site, the construction efficiency will be lowered, and the node structure is inconvenient to install
