[0002] In the steel pipe concrete column and H shaped steel connecting node, the strength of the connecting node is crucial to the structure. The H shaped steel connecting node refers to connecting the concrete column and the multiple H shaped steels together through the connecting piece, the connecting node needs to bear the large axial compression load from the H shaped steel, and also needs to bear the bending moment in the horizontal and vertical directions, is the multiple internal force concentration points, therefore the design and construction quality of the connecting node directly influence the safety and stability of the whole structure, the connecting form of the node is required to be higher, according to the form and the connecting mode of the connecting piece, the H shaped steel connecting node can be divided into several types such as welding connection, bolt connection and high-strength bolt connection. The most common application at present is to use bolting, and the bolting is used on the upper and lower flange plates and the web of the H shaped steel to make the node area meet the strength requirement in the horizontal and vertical directions. However, according to engineering experience, there are a large number of bolt operations in the node connecting area, which affects the installation and disassembly work of the supporting structure to some extent, and also reduces the strength of the node after long time use.

[0014] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0015] The utility model provides a kind of large-diameter steel pipe concrete column and H-shaped steel connecting joint as shown in Figures 1-2 It includes concrete column 100, and concrete column 100 is equipped with two interval settings connecting ring 110, four groups of limiting devices are equipped in two connecting rings 110, each group of limiting device includes two limiting plates 130 and two sleeves 140, one H-shaped steel 200 is connected in each group of limiting device, and the upper and lower flange plates of H-shaped steel 200 are equipped with several bolt holes two near connecting ring 110 side, two connecting rings 110 are equipped with bolt hole one 120 matched with bolt hole two.

[0016] Among them, connecting ring 110 is fixed on concrete column 100 by welding, the place where limiting plate 130 meets connecting ring 110 and concrete column 100 all adopt welding, the required strength demand in upper and lower directions of node can be met by the action of upper and lower connecting rings 110, and the use amount of bolt is reduced.

[0017] In some specific embodiments of the utility model, the two sleeves 140 of each group of limiting devices are located at the both sides of the web plate of H-shaped steel 200, and the both sides of the web plate of H-shaped steel 200 are equipped with reinforcing steel bar 210 matched with sleeve 140.
