In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

Referring to fig. 1 to 4, the round-roof angle beam-column connection corner fitting of the embodiment of the utility model includes three square tubes bent into an arc shape, and it should be noted that the square tubes in the embodiment of the utility model are bent square tubes which are processed into a predetermined shape, namely, an arc shape as shown in fig. 2, of conventional hollow square steel tubes in the prior market. The two ends of each square tube are respectively implemented as joints, which are defined as beam joints or column joints according to the members to be connected after assembly, that is, when the joints are connected as beam body members, the joints are defined as beam joints; when the joint connects the column members, the joint is defined as a column joint. In order to realize the assembly connection of three square pipes, a notch is formed in any joint position close to or near each square pipe, and the notch is used for the through nested connection of the square pipe and other two square pipes.

According to some preferred embodiments of the present utility model, as shown in fig. 2, either tube includes a central arcuate segment and straight segments disposed at opposite ends of the arcuate segment. Two notches on any square tube are respectively arranged on two straight sections of the square tube. Correspondingly, the two notches on the first square tube 1 are respectively described as follows: the notch at the upper end is described as a first notch 2 and the notch at the lower end is described as a second notch 3. The two notches in the second square tube 7 are described as follows: the notch at the upper end is described as a third notch 9 and the notch at the lower end is described as a fourth notch 8. The two notches of the third party tube 4 are described as follows: the notch at the left end is described as a fifth notch 5 and the notch at the right end is described as a sixth notch 6. The three square pipes are connected in such a way that the first notch 2 is nested with the third notch 9, the second notch 3 is nested with the fifth notch 5, and the fourth notch 8 is nested with the sixth notch 6. The arc section of the first square pipe 1 is described as a first arc section, the arc section of the second square pipe 7 is described as a second arc section, and the arc section of the third square pipe 4 is described as a third arc section.

For the bending radius of the arc-shaped section, the cross-section side length of the square tube is preferably more than or equal to 3 times. It should be noted that, the specific lengths of the arc-shaped sections and the straight sections are not particularly limited, and the above examples are only preferred, and are not meant to be limiting, and it is within the scope of the present utility model to increase or decrease the lengths of the arc-shaped sections and/or the straight sections. The notch is arranged at the same position on the straight section, that is to say, the distance between the notch and the end of the corresponding straight section or the distance between the notch and the intersection point of the corresponding straight section and the arc section is the same on any square tube. For example, any notch is opened at a distance of 20mm from the intersection point of the corresponding straight section and the corresponding arc section.

It should be noted that, as shown in fig. 2, two notches on any square tube are opened at different sides of the arc formed by the arc section. It should be noted that, the directions of placing the two vertically placed square tubes, that is, the first square tube 1 and the second square tube 7, are opposite during assembly, specifically, the placing position of the first square tube 1 is taken as a reference, and the second square tube 7 is just the upside down position of the first square tube 1. The third party tube 4 is rotated 90 degrees counterclockwise for the first square tube 1.
