In other words, the second stiffener provided in the brace joint system of a building according to another embodiment of the present invention will be described below.

6 is a perspective view showing a brace joint system of the building according to another embodiment of the present invention, Figure 7 is a schematic diagram showing the stress distribution of the brace joint system of the building according to another embodiment of the present invention.

Referring to FIG. 6, the module body 50 of the brace bonding system 100 of a building may include a module structure 52 and a second stiffener 154.

The module structure 52 is the same component as the module structure 52 in the above-mentioned embodiment, and the vertical joining plate 44 provided in the brace joint part 40 is joined up and down.

On the other hand, the module structure 52 may be provided as one of the H-shaped plate assembly structure, H-shaped steel or H beam on the cross-section that the plate is bonded. In addition, the module structure 52 includes a web 52c connecting upper and lower flanges 52a and 52b to upper and lower flanges 52a and 52b.

Meanwhile, both ends of the second stiffener 154 may be joined to the upper and lower flanges 52a and 52b, and one side may be joined to the web 52c. The second stiffener 154 may include a second vertical stiffener 154a and a second cross stiffener 154b.

One or more second vertical stiffeners 154a may be provided in the module structure 152 to transmit stresses provided to the module structure 52. That is, the second vertical stiffener 154a may be provided in the module structure 52 to connect the upper and lower flanges 52a and 52b in the vertical direction.

Accordingly, as in the above embodiment, the second vertical stiffener 154a smoothly receives the load applied from the brace member 10 of the building through the first stiffener 46 and the second vertical stiffener 154a. It acts to effectively implement stress distribution while flowing.

Meanwhile, at least one second cross stiffener 154b may be provided in the module structure 52 so as to be disposed on an extension line of the first stiffener 46 provided at the brace joint 40. In other words, the second cross stiffener 154b may be provided in the module structure 52 to be disposed on an extension line of the central axis of the building brace member 10 mounted on the brace joint 40.

In addition, the second crossing stiffener 154b may have an 'X' shape and may be disposed between the second vertical stiffeners 154a.

8 is a flowchart illustrating a construction method using a brace joint system of a building according to an embodiment of the present invention.

Referring to FIG. 8, first, the brace bonding module 30 is manufactured at a manufacturing site (S120). That is, the brace joint 40 and the module body 50 constituting the brace joint module 30 are bonded.

Thereafter, at least one building bracing member 10 is bonded to the brace bonding module 30 (S140). The building brace member 10 is bonded to the brace bonding plate 42 of the brace bonding portion 40, it can be bonded by welding.

In this embodiment, since the case in which four building bracing members 10 can be bonded to the brace bonding module 30 is described as an example, one building bracing member 10 is manufactured after the manufacture of the brace bonding module 30. It may be bonded to the brace bonding module 30.

However, the number of building brace members 10 that can be bonded to the brace bonding module 30 is not limited, and the number of building brace members 10 to be bonded at the manufacturing site is not limited to one.
